<hr />
<div>I know rachel is attempting her own bicycle lighting project, so I am hoping that by putting notes on the wiki we can share ideas. [[User:Rigel|Rigel]]<br />
<br />
==rigel's dynamo lighting system==<br />
<br />
This will be based around the Shimano DH-3N71 Dynamo hub. It outputs 3W at 6V. I'm not sure how the voltage or current changes as speed increases, but I am under the impression that it is fairly well-regulated internally.<br />
<br />
Currently, I have it wired directly to a rectifier, whose output is a 220uF cap and a Cree XR-E LED. This produces light adequate to ride in the dark and avoid most obstacles. None of this is regulated in any way, so at low (slightly faster than walking) speeds it begins to flicker. This might be a problem for long steep climbs in the dark.<br />
<br />
What I would like, ideally, is to have the ability to draw current from a li-ion battery pack when it begins to flicker. In addition, I would like to be able to charge the batteries, and additionally a cellphone if feasible, from the dynohub when i am riding in daylight. I have not found the drag to be noticeable from one LED, but presumably if drawing more current this could become a problem.<br />
<br />
Since I am a n00b, I dont know the first thing about implementing this, but i have been led (ha!) to believe that i need the following modules:<br />
<br />
*voltage regulator<br />
*battery charging circuit<br />
*led driver circuit<br />
*5V usb output for alternative uses<br />
<br />
The cree LEDs are brightest, i'm told, when drawing 600-700mA. The voltage drop, i believe, is 3.3v per LED, and they are best wired in series to avoid thermal runaway (not sure why this happens, but it's been talked about on several forums i've seen, so i think it best to avoid it altogether) I would probably start with 2, but may use as many as 4 li-ion cells for this purpose.<br />
<br />
==Additional tasks==<br />
*reflector design - will likely try to use the reprap for this. are there software packages for this sort of thing?<br />
<br />
==questions==<br />
<br />
*What voltage regulator should i use? <br />
- for a circuit that's powered by a battery only, no voltage regulator is required, at least not in general. if one uses a battery that provides too much voltage, then some means of dropping the voltage to the load circuit is needed (this can be diodes in series to the load). <br />
in the case of a battery and load being refreshed by a charger (e.g. something connected to pedals), then it's probably a good idea to protect from over-voltage (spikes) and to protect from possible reverse currents. <br />
- if power drain is a problem and you've determined you should use a voltage regulator, look at specs for switching regulators rather than linear regulators. --[[User:Jstockford|Jstockford]] 11:17, 26 November 2008 (PST) <br />
<br />
*do i need a multiple output voltage regulator or should i step up the voltage in the battery charger module itself?<br />
<br />
*what battery-charger IC should i use? <br />
- maybe none, possibly just passive components and diodes, maybe an active circuit using transistors or op amps. --[[User:Jstockford|Jstockford]] 11:17, 26 November 2008 (PST) <br />
<br />
*what kinds of interconnects (i would like this to be modular for the working design) are waterproof (and cheap!), as i will be using this in potentially foul weather?<br />
<br />
* where is this circuit physically (might be no where at the moment, might be bits and pieces on a bike or on a shelf...). --[[User:Jstockford|Jstockford]] 11:21, 26 November 2008 (PST)</div>Jstockfordhttps://www.noisebridge.net/index.php?title=BicycleLighting&diff=2498BicycleLighting2008-11-26T19:17:30Z<p>Jstockford: /* questions */ with suggestions 20081126</p>

<hr />
<div>Workshop proposal: '''Hack your Hardware''' [[User:Jtfoote|Jtfoote]] 14:11, 7 November 2008 (PST)<br />
<br />
"No user-serviceable parts inside" -- we call bullshit on that!<br />
<br />
Bring in your hardware yearning to reach its maximum potential (or give its life for spare parts). We give you permission to take things apart, see what's inside, and improve them. Most electronics failures are caused by bad connections or simple mechanical problems: we'll show you what to look for and how to fix them. Favorite gadget busted? Don't throw it away; fix it! (Or at least autopsy it for the good of science!) <br />
<br />
Possible projects:<br />
<br />
* Add an extra iPod input jack to your clock radio or computer speakers<br />
* Add a USB hub to a desk lamp (or a bobblehead doll, or a stuffed toy, or...)<br />
* Hotrod your IR remote control to extend the range<br />
* Extract DC motors and other good stuff from that CD player found on the sidewalk<br />
* Fix that funky power jack on your old laptop so you can give it to Mom<br />
* Add another headphone jack (or FM transmitter?) to your laptop<br />
* Add a LED backlight or tasklight to a keyboard or a handheld game<br />
* Add a secondary switch or a dimmer to a power strip<br />
* A one-wire hack turns a discarded ATX PSU into a benchtop power supply <br />
* Replace the tired nicads in your electric toothbrush (or power screwdriver, or other rechargeable gizmo)<br />
* Hotrod your favorite power screwdriver with Li+ batteries<br />
* Circuit-bend that electronic toy for an even more annoying sound<br />
<br />
You will have more and better ideas. Bring them and share! (I personally will be adding a pilot light to my desoldering gun so I can tell when it's plugged in and thus burninatingly hot.)<br />
<br />
Yes this could be dangerous, and we may break things. That's how we learn.<br />

<br />
<br />
==Transit status information==<br />
<br />
I've written something that uses [http://www.bart.gov/schedules/developers/etas.aspx] together with Festival to give announcements about BART trains approaching 16th Street. I intend on setting this up with a cron job to run around the time of the scheduled last trains every night (and maybe the first train in the morning if we think people may frequently stay until around 4:00 a.m.!), using the music server once it's stable. To avoid annoying people this should probably not be configured to make regular announcements at other times. Two extensions to make this more useful: (1) if we can get or make a USB-to-buttons/switches or parallel-port-to-buttons/switches adapter, we can have a big button somewhere that causes an announcement to occur (for use when people are thinking of catching BART and want to know when it's coming). (2) If we can get a big scrolling LED sign with computer control, we can have it constantly display train status -- as well as Muni bus announcements with data from [http://www.nextbus.com/ NextBus], perhaps using a library to get it. [[User:Schoen|Schoen]] 23:30, 9 October 2008 (PDT)<br />
<br />
==RepRap==<br />
<br />
RepRaps are a kind of homemade 3D printers capable of self-replicating, as well as being used for rapid prototyping and manufacturing. There is interest in constructing a RepRap at NoiseBridge. See [[RepRap]].<br />
<br />
<br />
==Ambient Activity Mutating Space==<br />
<br />
Place properly signed microphones in part of the space. Pick up conversations, feed them to voice recognition software. Extract nouns and phrases from the results. Render the top results from searching these phrases on displays in the space, twitter them on the Noisebridge twitter stream, and do other fun things. Maybe also do gesture recognition, too. See [[Ambient Activity Mutating Space]].<br />
<br />
<br />
== Pancakes ==<br />
<br />
there's a saying to the effect that the first batch is always ruined. a similar saying says don't buy any software with a rev of 1.0. is there such a saying about wikis? should there be? what about refactoring this wiki so's to make it easier to navigate (e.g. don't have two separate "infrastructure" sections)? --[[User:Jstockford|Jstockford]] 16:38, 19 October 2008 (PDT)<br />
<br />
This falls very much into the category of Just Do It. That said, it's a fairly big job that I personally have not found time to take on. If anyone wants to collaborate on wiki reorganization I'm up for that (I like Organized). [[User:Rachel|Rachel]] 16:49, 19 October 2008 (PDT)<br />
<br />
see discussion page for collaboration. --[[User:Jstockford|Jstockford]] 21:59, 19 October 2008 (PDT)<br />
<br />
<br />
== Electronics Essentials ==<br />
<br />
seems likely that people working on electronic projects would find a variable power supply and a function generator handy along with some other basic test gear (e.g. pink noise generator, resistance bridge, LC measuring device...). many such things are available as kits. i've got one or two myself and would like to build them down there and leave them for people to use. what cautions wrt other peoples' careful use? signs or brief instruction sheets helpful? --[[User:Jstockford|Jstockford]] 16:38, 19 October 2008 (PDT) <br />
<br />
anyone want to collaborate on building kits and devices? [[OtherElectronicProjects]] --[[User:Jstockford|Jstockford]] 16:38, 19 October 2008 (PDT)<br />
<br />
I brought some random retro gear along those lines, they're on a shelf labeled as donated by Skory. If they look of use please take them and have your way with them. --[[User:elgreengeeto|elgreengeeto]]<br />
<br />
I bought a bunch of cheap but universally useful components: about 1000 resistors, 300 capacitors, diodes, wire, etc. I'm taking suggestions for other cheap but handy electronics I aught buy in bulk. [[User:dstaff|dstaff]].<br />
<br />
<br />
==Python classes==<br />
<br />
Proposed at [[Python classes]]. [[User:Schoen|Schoen]] 21:20, 26 October 2008 (PDT)<br />
<br />
<br />
==Pimping up the lights==<br />
<br />
I want to pimp up Noisebridge's lights with a digital web-controlled interface. (Don't worry, there will still be switches that just-work.) See [[Lighting]]. Once I have enough work done, I'll bring it up at a meeting. If anyone wants to help with construction or software, let me know. I think I have the electronics under control. -- [[user:Dstaff|Dstaff]]<br />
<br />
how about LED lights on a 12VDC circuit? --[[User:Jstockford|Jstockford]] 08:55, 14 November 2008 (PST)<br />
<br />
<br />
==Gastrohacking SOE==<br />
<br />
We are enough mad food hackers that we should make sure that a ''SubOrganizational Entity'' with regular [[Gastrohacking|food hacking]] meet-ups, events, workshops, cook-offs, and participation in [http://blog.khymos.org/2007/05/02/tgrwt-1-roundup-coffee-chocolate-garlic/ TGRWT] challenges.<br />
We would like to work our way through the recipes or ideas from the great scientific chefs: [http://en.wikipedia.org/wiki/Ferran_Adria Ferran Adria], [http://en.wikipedia.org/wiki/Heston_Blumenthal Heston Blumenthal] et.c. Make things like: Blue cheese / chocolate souffle and lemon tempura with licorice. Build and use a [http://www.nytimes.com/2005/08/14/magazine/14CRYOVAC.html?pagewanted=1&ei=5090&en=3d5db17005368139&ex=1281672000&partner=rssuserland&emc=rss sous vide bath] and a computer controlled automated bbq.<br />
<br />
<br />
==Wiki Watch== <br />
<br />
the wiki is getting wacky. over time it may get so crufty as to be unhelpful. this "concept" suggests some of us pay attention to our wiki to keep it useful, something like managing a garden: <br />
* some items are old and no longer useful, like weeds, they should be removed. if an audit trail or history is needed, move old stuff to an antiquities section. <br />
* there are redundancies which should be consolidated (move all the gardenias to the same bed). <br />
* it might be nice to use the discussion (talk) pages more and the article pages less so the text on the article pages reflects concensus of the discussion (and reduces the amount of words the reader must slog through). <br />
* wiki technologies offer some features that might be good to promote. an example is "categories": if you look at special pages, you'll see a categories page listed; click it and you'll see the categories, one of which is "projects". it might be nice that we're aware of the projects category and tag some articles as projects. the benefit is easier wiki navigation. the downside, of course, is that all humans, even enlightened intelligent and well-meaning humans, are at times douchebags and won't bother to read about how to do things in ways other than what the current feelings dictate. <br />
<br />
if you have feelings about watching the wiki, add your voice, please. perhaps we can get up a wikiwatch group to encourage each other to manage the mess. --[[User:Jstockford|Jstockford]] 09:13, 14 November 2008 (PST) <br />
<br />
<br />
==Getting and Giving Stuff== <br />
if we get stuff, where to put it? there are the sharing and hacking shelves, probably incoming should go on one of those two sets. <br />
<br />
it would be nice to have an outgoing shelf, a place to put stuff that we no longer want. maybe the very bottom shelf in the hacking set? other? <br />
<br />
how about trips to take stuff to ACCRC? a trip to ACCRC could be just to take stuff, just to see the place, just to spend time working as volunteers, or some combo. --[[User:Jstockford|Jstockford]] 10:35, 17 November 2008 (PST)</div>Jstockfordhttps://www.noisebridge.net/index.php?title=Trip_to_Shooting_Range&diff=2315Trip to Shooting Range2008-11-14T22:36:10Z<p>Jstockford: /* Interested Parties */</p>
<hr />
<div>There is some interest in a field trip to a shooting range to shoot guns in a Safe and Orderly manner. If you're interested, list your name below, along with any time restrictions and whether you are able to drive a carpool. The nearest range to 83C is, to the best of my knowledge, Jackson Arms in SSF.<br />
<br />
No previous knowledge or experience is required. If you always wanted to try shooting a gun, this is a good opportunity for that.<br />

<hr />
<div>There is some interest in a field trip to a shooting range to shoot guns in a Safe and Orderly manner. If you're interested, list your name below, along with any time restrictions and whether you are able to drive a carpool. The nearest range to 83C is, to the best of my knowledge, Jackson Arms in SSF.<br />
<br />
No previous knowledge or experience is required. If you always wanted to try shooting a gun, this is a good opportunity for that.<br />
<br />
== Date & Time ==<br />
<br />
??? a weekend? Someone look up ranges and their hours, also whether they require a training course or not.<br />

==Transit status information==<br />
<br />
I've written something that uses [http://www.bart.gov/schedules/developers/etas.aspx] together with Festival to give announcements about BART trains approaching 16th Street. I intend on setting this up with a cron job to run around the time of the scheduled last trains every night (and maybe the first train in the morning if we think people may frequently stay until around 4:00 a.m.!), using the music server once it's stable. To avoid annoying people this should probably not be configured to make regular announcements at other times. Two extensions to make this more useful: (1) if we can get or make a USB-to-buttons/switches or parallel-port-to-buttons/switches adapter, we can have a big button somewhere that causes an announcement to occur (for use when people are thinking of catching BART and want to know when it's coming). (2) If we can get a big scrolling LED sign with computer control, we can have it constantly display train status -- as well as Muni bus announcements with data from [http://www.nextbus.com/ NextBus], perhaps using a library to get it.

<br />
==RepRap==<br />
<br />
RepRaps are a kind of homemade 3D printers capable of self-replicating, as well as being used for rapid prototyping and manufacturing. There is interest in constructing a RepRap at NoiseBridge. See [[RepRap]].<br />
<br />
<br />
==Ambient Activity Mutating Space==<br />
<br />
Place properly signed microphones in part of the space. Pick up conversations, feed them to voice recognition software. Extract nouns and phrases from the results. Render the top results from searching these phrases on displays in the space, twitter them on the Noisebridge twitter stream, and do other fun things. Maybe also do gesture recognition, too. See [[Ambient Activity Mutating Space]].<br />

there's a saying to the effect that the first batch is always ruined. a similar saying says don't buy any software with a rev of 1.0. is there such a saying about wikis? should there be? what about refactoring this wiki so's to make it easier to navigate (e.g. don't have two separate "infrastructure" sections)? --[[User:Jstockford|Jstockford]] 16:38, 19 October 2008 (PDT)<br />
<br />
This falls very much into the category of Just Do It. That said, it's a fairly big job that I personally have not found time to take on. If anyone wants to collaborate on wiki reorganization I'm up for that (I like Organized). [[User:Rachel|Rachel]] 16:49, 19 October 2008 (PDT)<br />

<br />
<br />
==Wiki Watch== <br />
<br />
the wiki is getting wacky. over time it may get so crufty as to be unhelpful. this "concept" suggests some of us pay attention to our wiki to keep it useful, something like managing a garden: <br />
* some items are old and no longer useful, like weeds, they should be removed. if an audit trail or history is needed, move old stuff to an antiquities section. <br />
* there are redundancies which should be consolidated (move all the gardenias to the same bed). <br />
* it might be nice to use the discussion (talk) pages more and the article pages less so the text on the article pages reflects concensus of the discussion (and reduces the amount of words the reader must slog through). <br />
* wiki technologies offer some features that might be good to promote. an example is "categories": if you look at special pages, you'll see a categories page listed; click it and you'll see the categories, one of which is "projects". it might be nice that we're aware of the projects category and tag some articles as projects. the benefit is easier wiki navigation. the downside, of course, is that all humans, even enlightened intelligent and well-meaning humans, are at times douchebags and won't bother to read about how to do things in ways other than what the current feelings dictate. <br />
<br />
if you have feelings about watching the wiki, add your voice, please. perhaps we can get up a wikiwatch group to encourage each other to manage the mess. --[[User:Jstockford|Jstockford]] 09:13, 14 November 2008 (PST)</div>Jstockfordhttps://www.noisebridge.net/index.php?title=Concepts&diff=2297Concepts2008-11-14T16:56:50Z<p>Jstockford: /* Transit status information */</p>

==Transit status information==<br />
<br />
I've written something that uses [http://www.bart.gov/schedules/developers/etas.aspx] together with Festival to give announcements about BART trains approaching 16th Street. I intend on setting this up with a cron job to run around the time of the scheduled last trains every night (and maybe the first train in the morning if we think people may frequently stay until around 4:00 a.m.!), using the music server once it's stable. To avoid annoying people this should probably not be configured to make regular announcements at other times. Two extensions to make this more useful: (1) if we can get or make a USB-to-buttons/switches or parallel-port-to-buttons/switches adapter, we can have a big button somewhere that causes an announcement to occur (for use when people are thinking of catching BART and want to know when it's coming). (2) If we can get a big scrolling LED sign with computer control, we can have it constantly display train status -- as well as Muni bus announcements with data from [http://www.nextbus.com/ NextBus], perhaps using a library to get it.

==RepRap==<br />
<br />
RepRaps are a kind of homemade 3D printers capable of self-replicating, as well as being used for rapid prototyping and manufacturing. There is interest in constructing a RepRap at NoiseBridge. See [[RepRap]].<br />
<br />
<br />
==Ambient Activity Mutating Space==<br />
<br />
Place properly signed microphones in part of the space. Pick up conversations, feed them to voice recognition software. Extract nouns and phrases from the results. Render the top results from searching these phrases on displays in the space, twitter them on the Noisebridge twitter stream, and do other fun things. Maybe also do gesture recognition, too. See [[Ambient Activity Mutating Space]].<br />

=== When? === <br />
<br />
Sunday, november 16th, 3:00PM to 4:30PM. <br />
<br />
=== Who? ===<br />
<br />
David Stafford (me! http://www.ugcs.caltech.edu/~dstaff/david.jpg) and anyone who decides to help me will be teaching the class. <br />
<br />
Anyone who already has minimal electronics experiance. If you've built even very basic circuits before, you're probably fit for this class.<br />
<br />
=== How many? ===<br />
<br />
We will have three oscilloscopes for the class. Six people can work in teams of two. If someone<br />
can lend an oscilloscope for the class, we can have 8 people. Please sign up below and write something about what you want to learn so I can better target the class. <br />
<br />
* Jacob (I'm just along for the ride, I'd like to better my understanding of triggers, etc)<br />
* [[User:Adi|adi]] (I'm a digital scope boy livin' in an analog scope world)<br />
* slot 3 [[User:jstockford|jim]] i can bring a scope <br />
* slot 4<br />
* slot 5<br />
* slot 6<br />
<br />
=== What? ===<br />
<br />
Topics to be covered include:<br />
* Basics: how a CRT scope works<br />
* Probe selection and calibration<br />
* Measuring a constant voltage<br />
* Changing voltages: triggering, AC versus DC coupling <br />
* Looking at multiple signals<br />
* Measuring complex signals: more triggering techniques. <br />
<br />
You'll work in pairs analyzing various aspects of a simple 555 oscilator circuit and an EL wire<br />
driver. The class should take between 60 and 90 minutes. I epxect 90% of the class to be hands on<br />
with little or no "lecture" time.<br />

<br />
An introduction to the Atmel AVR family of microcontrollers by [[User:Mightyohm|Jeff]] and [[User:Maltman23|Mitch]].<br />
<br />
The curriculum has not been determined, yet, but will include:<br />
* basic electronics<br />
* intro to microcontrollers<br />
* build your own AVR programmer<br />
* how to set up your computer to develop your microcontroller projects<br />
* build a bunch of simple, fun projects, each of which will teach a fundamental microcontroller concept<br />
<br />
Microcontrollers are very cheap (as little as $0.50 for the simplest ones), and very powerful! With them you can do an amazingly diverse range of projects, anywhere from turning TVs off in public places, to playing computer games, to making robots move or see, to creating beautiful (or obnoxious) music, to anything your imagination can come up with! And anyone can learn to make their own projects with them, given a little background.<br />
<br />
The Atmel AVR family microcontrollers are very easy-to-use, and easy-to-learn. There are lots of free, open-source tools available for it, and lots of open-source projects that have all documentation free for the download online. There is also a user forum called AVRfreaks.org, full of geeks all over the world, 24/7, just waiting to answer your questions about your AVR microcontroller project. For these reasons, and more, it is a very popular family of microcontrollers for the DIY (Do It Yourself) crowd, which is why we've chosen to use it for this set of classes.<br />

<hr />
<div>I'm an enthusiastic user of the Python programming language, although I don't get to exercise my skills enough since I program only infrequently for work and for hobby projects. I've enjoyed teaching Python at work to people who were mostly nonprogrammers and I'd like to find more opportunities to teach, so I'd be glad to try to set up either a Python class for nonprogrammers or a Python class for non-Python programmers at Noisebridge.<br />
<br />
Two problems I've encountered when teaching coworkers are how to get (the same set of) people to attend regularly and how to get people to do homework or practice outside of class. I guess in an academic setting these problems are often handled by giving letter grades for attendance (or testing), which doesn't work well in a volunteer class setting.<br />
<br />
Is anybody interested in this? [[User:Schoen|Schoen]] 21:18, 26 October 2008 (PDT)<br />

me, i'm interested in python. can you teach me what is "pythonic"? can you help me to use any of the zillions of modules that pack the planet? --[[User:Jstockford|Jstockford]] 20:36, 28 October 2008 (PDT) <br />

<hr />
<div>Rachel's techniques for sewable circuitry: seems somehow soldering SMB parts to make them sewable. Related idea is flexible printed circuit boards. <br />
<br />
<br />
(i believe that) Meredith asked for a Theremin-like means for turning water on and off: the water source could be a bottle with a siphon hose and clamp or inverted bottle with hose and clamp; clamp could be controlled by some kind of motor, maybe stepper motor, which would be controlled by the Theremin-like circuit. <br />
<br />
<br />
Use MOSFETS instead of bipolar diodes: the voltage drop across a standard diode is about 0.7 Volts. It seems it's possible to use a MOSFET (metal oxide over semiconductor field effect transistor) as a diode in drain follower mode. The voltage drop is much less than across a standard diode. as more amperage goes through the diode, more power is wasted. also for circuits with very low voltage power sources, because there is very little voltage drop, more voltage is available for the circuit load. I'd like to build a circuit or two to test this. Applications include remote, low-power systems. <br />
http://electronicdesign.com/Articles/ArticleID/19871/19871.html <br />
<br />
check out Schottky and germanium diodes if you are concerned with forward voltage drop. <br />
The parasitic diodes in MOSFETs have large parasitic capacitances and long recovery times. <br />
<br />
"Ultimate Continuity Tester", per Electronic Design, October 2, 2008: The article claims normal continuity testers trigger through connections of as much as a few hundred Ohms, which sometimes is too crude. Sometimes what's needed is a continuity detector that will not trigger through as little as ten Ohms. The circuit described is cheap, robust, and very sensitive. I'd like to try to build this. <br />

<br />
Sounds like you care about the actual resistance, which you can easily measure with an ohmmeter. <br />
Something you could do is make a 555 audio oscillator with resistance across the test probes <br />
influencing the frequency. That would give you audible feedback of magnitude rather than a <br />
binary go/no-go test. [[User:67.101.45.157|67.101.45.157]] 19:58, 27 October 2008 (PDT)<br />

Amplifier for function generator: it's nice to have an amplifier and speaker combo around for testing. There are various ICs that are pretty good audio amps, given a power supply and a few components. <br />
<br />
You can scavenge some cheap computer speakers off the street or at Goodwill, and need not worry about frying them. <br />
<br />
Audio mixer: it'd be a fun hack to mix the outputs of function generators and other audio range signal generators. <br />
<br />
<br />
Audio cube: the idea is for eight independent audio amplifier-speaker combos in each corner of a cube with a mixer that could send signals to any combination. the control for the mixer seems tricky: a multiple pot comes to mind as does a cubic container with semi-conductive liquid with terminals in each corner of the cube and a stick with an end that presents a signal source to the liquid. There's always the CPU method of spitting bit slices to each corner amp per user-interactive controlled algorithms (the GUI or CLI user interface seems problematic in the same way as the physical interface, though the user could set things up programmatically--though this is reminiscent of punch card programming). <br />
<br />
<br />
Power test resistors: a few 100 Watt resistors of various sizes could be useful. If i find some, I'll bring them in. <br />
<br />
<br />
Multiple voltage power supply: a single device (i.e. a single 120VAC power plug) that provides various positive and negative voltages, probably most limited to less than one Amp. These are available, but in limited combinations: the hack proposed would allow any kind of extensibility.<br />
<br />
you can make a (positive DC at least) adjustable power supply like that with a wall wart and a fifty-cent LM317 <br />
<br />
and an LM 337 can provide negative DC adjustable power supply. probably both are better with a cap or two. exar makes a 4195 dual tracking +-15 VDC regulator (i like exar, they seem to have good knock-offs). <br />
<br />
<br />
Anything with 12VDC, low voltage, low power, off-the-grid.... <br />
<br />
<br />
Is it possible to make a signal generator that drives an antenna at the frequency of visible light? Here's the tho't: we hear multiple octaves, about ten or so (piano-type keyboard devices generally support several octaves, a guitar supports four or five octaves...). But we see just a little less than one octave (we see a low frequency red through orange, yellow, green, blue, upper frequency violet; below red is infrared, above violet is ultraviolet, an octave is just below red to just above violet). I think it's possible, conceivable anyway, that we can train ourselves to expand our visual perception: to recognize a little below and a little above what we're used to and possibly stretch enough to see the octave: an infrared color that is half the frequency of an ultraviolet color. Singers exercise their voices to extend their ranges both downward and upward. It may be possible. If so, for the person who achieves this, their sense of color harmony will change, for in recognizing an octave in light, they can make better sense of harmonic relations that are apparent in music (the fifth and fourth degrees of a scale, major and minor thirds and sixths, augmented and diminished chord...). But the trick is training, and for that it seems is needed an antenna that generates light and can be modulated to produce the entire visible spectrum and beyond, both above and below.<br />

<div>Rachel's techniques for sewable circuitry: seems somehow soldering SMB parts to make them sewable. Related idea is flexible printed circuit boards. <br />
<br />
<br />
(i believe that) Meredith asked for a Theremin-like means for turning water on and off: the water source could be a bottle with a siphon hose and clamp or inverted bottle with hose and clamp; clamp could be controlled by some kind of motor, maybe stepper motor, which would be controlled by the Theremin-like circuit. <br />
<br />
<br />
Use MOSFETS instead of bipolar diodes: the voltage drop across a standard diode is about 0.7 Volts. It seems it's possible to use a MOSFET (metal oxide over semiconductor field effect transistor) as a diode in drain follower mode. The voltage drop is much less than across a standard diode. as more amperage goes through the diode, more power is wasted. also for circuits with very low voltage power sources, because there is very little voltage drop, more voltage is available for the circuit load. I'd like to build a circuit or two to test this. Applications include remote, low-power systems. <br />

"Ultimate Continuity Tester", per Electronic Design, October 2, 2008: The article claims normal continuity testers trigger through connections of as much as a few hundred Ohms, which sometimes is too crude. Sometimes what's needed is a continuity detector that will not trigger through as little as ten Ohms. The circuit described is cheap, robust, and very sensitive. I'd like to try to build this. <br />

<br />
<br />
Workshop electrical upgrade is now done. <br />
<br />
<br />
More to do: <br />
<br />
THE LOFT: how to improve the electricity for the upstairs ("loft"?). <br />
* how to get pipe up there: across ceiling and wall surfaces is best, minimize punching holes and trying to fish within walls. <br />
* there may be an accessible branch point (at the j-box in the toilet room or in the subpanel itself) where it's possible to break the connection to the upstairs #14 receptacles, presenting the job of getting wires from the subpanel to that point. <br />
* the loft has two circuits, #14 and #15. what power is required? issues are heavy loads and noisy loads. motors are both heavy (draw a lot of amps) and noisy (spikes and lows as motor turns off and on); heaters (hair dryers, hot plates...) are only heavy; some electronic devices can be noisy (return high-frequency waveforms into the line, often on the neutral return). <br />
SO WHAT IS THE EXPECTED USE IN THE LOFT? <br />
<br />
:The loft will have two large electric users -- soldering irons, and rackmount computers. I would expect a max of 5 200W soldering irons in use (call it 10 Amps), and a max of 10 machines at 200w each, or about 17 A. (Some of the machines will draw more but most will draw less.) We should verify the specs on the large UPS that's upstairs. There will also be misc users like lab gear, maybe another 5A to be generous. [[User:Adi|Adi]] 11:45, 7 October 2008 (PDT)<br />
:NOTE: solder irons for electronics are 25W or 35W, so 5 of them on at once is about 2 A (rounded up). [[User:maltman23|Mitch Altman]] 11:55, 7 October 2008 (PDT) <br />
:this is my experience also. there are soldering guns and irons of 100W, but for electronic work they have only occasional use. --[[User:Jstockford|Jstockford]] 12:11, 7 October 2008 (PDT) <br />
:if soldering is done upstairs, good chance people will be screwing around with electronic circuits, which presents the chance of inadvertent short circuits. probably good for electronicists to plug into fused receptacles, which could be little gizmos that plug into wall receptacles and present fused receptacles on the working side. i'd guess 5A would be plenty for most projects (including scopes, meters, soldering stations, circuits under test...). --[[User:Jstockford|Jstockford]] 12:11, 7 October 2008 (PDT) <br />
:a dedicated 20A circuit is needed for the computer equipment. most 1U boxes suck 1A. it will be helpful to know <br />
* the specs for the rack itself (how many units), four-post or two-post, shelves etc available? <br />
and for <br />
** each machine (1U or 2U or what, and amperage for each). <br />
so how to run the dedicated circuit? --[[User:Jstockford|Jstockford]] 12:28, 7 October 2008 (PDT) <br />
<br />
<br />
OTHER: there are other possible useful projects: <br />
<br />
* shannon clark in email raised a good point: task lighting for workstations. this applies not only to the electronic workstations in the loft but all workstations (in the fishbowl, chemistry, darkroom, computer stations...). a NOTE above suggests not letting a circuit power both lights and receptacles. as long as some light is lit when a breaker trips, safety concerns are okay. more receptacles can come from power strips or from adapters that plug into a duplex and present six receptacles. task lights should be considered in figuring circuit loads. --[[User:Jstockford|Jstockford]] 12:37, 7 October 2008 (PDT) <br />
<br />
* isolated AC 110: get an isolation (1:1) transformer and put a receptacle on its secondary or get two identical step(down | up) transformers, hook one primary to AC, connect secondaries, hook a receptacle to the other primary winding. <br />
:BENEFIT: isolated ground, reduced problems with noise and electrical shock hazard. <br />
<br />
* UPS: probably good to have transformer isolation, but at any rate, make a circuit that charges a battery that can kick in to power an AC 110 emergency circuit, features can include some electronic notification of switchover and a warning of battery-too-low condition, even logging. more Amperage (i.e. more Watts) requires more money, lots more. --[[User:Jstockford|Jstockford]] 12:11, 7 October 2008 (PDT) <br />
<br />
* complementary 12 VDC or other DC power system. could use uncomplicated battery backup to provide emergency power (lights, laptops). (there are 24VDC, 48VDC... (i like +12VDC with -12VDC dual tracking, but that's probably an audio-only approach).<br />
<br />
* it might be nice to put some kind of spike/noise suppression on certain circuits, both to protect their devices from the clatter of other circuits as well as to prevent their clatter from bleeding out to other circuits. --[[User:Jstockford|Jstockford]] 12:28, 7 October 2008 (PDT)</div>Jstockfordhttps://www.noisebridge.net/index.php?title=OtherElectronicProjects&diff=1900OtherElectronicProjects2008-10-26T17:01:01Z<p>Jstockford: one nother idea (meredith) and slight rewrites to some of the originals.</p>

Rachel's techniques for sewable circuitry: seems somehow soldering SMB parts to make them sewable. Related idea is flexible printed circuit boards. <br />
<br />
<br />
Use MOSFETS instead of bipolar diodes: the voltage drop across a standard diode is about 0.7 Volts. It seems it's possible to use a MOSFET (metal oxide over semiconductor field effect transistor) as a diode in drain follower mode. The voltage drop is much less than across a standard diode. as more amperage goes through the diode, more power is wasted. also for circuits with very low voltage power sources, because there is very little voltage drop, more voltage is available for the circuit load. I'd like to build a circuit or two to test this. Applications include remote, low-power systems. <br />

<br />
"Ultimate Continuity Tester", per Electronic Design, October 2, 2008: The article claims normal continuity testers trigger through connections of as much as a few hundred Ohms, which sometimes is too crude. Sometimes what's needed is a continuity detector that will not trigger through as little as ten Ohms. The circuit described is cheap, robust, and very sensitive. I'd like to try to build this. <br />
http://electronicdesign.com/Articles/Index.cfm?AD=1&ArticleID=19768&bypass=1 <br />
<br />
<br />
Amplifier for function generator: it's nice to have an amplifier and speaker combo around for testing. There are various ICs that are pretty good audio amps, given a power supply and a few components. <br />
<br />
<br />
Audio mixer: it'd be a fun hack to mix the outputs of function generators and other audio range gizmos. <br />
<br />
<br />
Audio cube: the idea is eight independent audio amplifier-speaker combos in each corner of a cube with a mixer that could send signals to any combination. the control for the mixer seems tricky: a multiple pot comes to mind as does a cubic container with semi-conductive liquid with terminals in each corner of the cube and a stick with an end that presents a signal source to the liquid. There's always the CPU method of spitting bit slices to each corner amp per user-interactive controlled algorithms (the GUI or CLI user interface seems problematic). <br />
<br />
<br />
Power test resistors: a few 100 Watt resistors of various sizes could be useful. <br />
<br />
<br />
Multiple voltage power supply: a single device (i.e. a single 120VAC power plug) that provides various positive and negative voltages, probably most limited to less than 1 Amp.</div>Jstockfordhttps://www.noisebridge.net/index.php?title=OtherElectronicProjects&diff=1893OtherElectronicProjects2008-10-26T02:21:17Z<p>Jstockford: a few electronic project ideas.</p>

==e-ink display==<br />
<br />
Get our hands on as many October '08 Esquire e-ink magazine [http://blog.makezine.com/archive/2008/09/esquire_eink_cover_hackin.html covers] as possible and rewire them into tiles of one big low-power display. (PY's idea originally. [[User:Elgreengeeto | -elgreengeeto ]]). Or, alternatively, just try to get some e-ink bulk from China and make an even cooler low-power display.<br />
<br />
<br />
==Transit status information==<br />
<br />
I've written something that uses [http://www.bart.gov/schedules/developers/etas.aspx] together with Festival to give announcements about BART trains approaching 16th Street. I intend on setting this up with a cron job to run around the time of the scheduled last trains every night (and maybe the first train in the morning if we think people may frequently stay until around 4:00 a.m.!), using the music server once it's stable. To avoid annoying people this should probably not be configured to make regular announcements at other times. Two extensions to make this more useful: (1) if we can get or make a USB-to-buttons/switches or parallel-port-to-buttons/switches adapter, we can have a big button somewhere that causes an announcement to occur (for use when people are thinking of catching BART and want to know when it's coming). (2) If we can get a big scrolling LED sign with computer control, we can have it constantly display train status -- as well as Muni bus announcements with data from [http://www.nextbus.com/ NextBus], perhaps using a library to get it.

<br />
==T-shirt printer==<br />
<br />
I'm still looking into the best way to do it, but some sort of t-shirt printer would be fun and useful. Seems that direct to cloth ink-jet techniques don't look as good as silk screening, but old-fashioned silk-screen is hella old-fashioned. Maybe some way to achieve silk screening results but with only limited human-interference? I'm thinking that proceeds from über-fashionable Noisebridge t-shirt sales would eventually off-set costs of this project. [[User:elgreengeeto|elgreengeeto]] 16:32, 10 October 2008 (PDT)<br />
<br />
<br />
==RepRap==<br />
<br />
RepRaps are a kind of homemade 3D printers capable of self-replicating, as well as being used for rapid prototyping and manufacturing. There is interest in constructing a RepRap at NoiseBridge. See [[RepRap]].<br />
<br />
<br />
==Ambient Activity Mutating Space==<br />
<br />
Place properly signed microphones in part of the space. Pick up conversations, feed them to voice recognition software. Extract nouns and phrases from the results. Render the top results from searching these phrases on displays in the space, twitter them on the Noisebridge twitter stream, and do other fun things. Maybe also do gesture recognition, too. See [[Ambient Activity Mutating Space]].<br />
<br />
<br />
== Pancakes ==<br />
<br />
there's a saying to the effect that the first batch is always ruined. a similar saying says don't buy any software with a rev of 1.0. is there such a saying about wikis? should there be? what about refactoring this wiki so's to make it easier to navigate (e.g. don't have two separate "infrastructure" sections)? --[[User:Jstockford|Jstockford]] 16:38, 19 October 2008 (PDT)<br />
<br />
This falls very much into the category of Just Do It. That said, it's a fairly big job that I personally have not found time to take on. If anyone wants to collaborate on wiki reorganization I'm up for that (I like Organized). [[User:Rachel|Rachel]] 16:49, 19 October 2008 (PDT)<br />

<br />
== Electronics Essentials ==<br />
<br />
seems likely that people working on electronic projects would find a variable power supply and a function generator handy along with some other basic test gear (e.g. pink noise generator, resistance bridge, LC measuring device...). many such things are available as kits. i've got one or two myself and would like to build them down there and leave them for people to use. what cautions wrt other peoples' careful use? signs or brief instruction sheets helpful? --[[User:Jstockford|Jstockford]] 16:38, 19 October 2008 (PDT) <br />

RepRaps are a kind of homemade 3D printers capable of self-replicating, as well as being used for rapid prototyping and manufacturing. There is interest in constructing a RepRap at NoiseBridge. See [[RepRap]].<br />

==Ambient Activity Mutating Space==<br />
<br />
Place properly signed microphones in part of the space. Pick up conversations, feed them to voice recognition software. Extract nouns and phrases from the results. Render the top results from searching these phrases on displays in the space, twitter them on the Noisebridge twitter stream, and do other fun things. Maybe also do gesture recognition, too. See [[Ambient Activity Mutating Space]].<br />

there's a saying to the effect that the first batch is always ruined. a similar saying says don't buy any software with a rev of 1.0. is there such a saying about wikis? should there be? what about refactoring this wiki so's to make it easier to navigate (e.g. don't have two separate "infrastructure" sections)? --[[User:Jstockford|Jstockford]] 16:38, 19 October 2008 (PDT)<br />
<br />
This falls very much into the category of Just Do It. That said, it's a fairly big job that I personally have not found time to take on. If anyone wants to collaborate on wiki reorganization I'm up for that (I like Organized). [[User:Rachel|Rachel]] 16:49, 19 October 2008 (PDT)<br />

== Electronics Essentials ==<br />
<br />
seems likely that people working on electronic projects would find a variable power supply and a function generator handy along with some other basic test gear (e.g. pink noise generator, resistance bridge, LC measuring device...). many such things are available as kits. i've got one or two myself and would like to build them down there and leave them for people to use. what cautions wrt other peoples' careful use? signs or brief instruction sheets helpful? --[[User:Jstockford|Jstockford]] 16:38, 19 October 2008 (PDT) <br />

<br />
==e-ink display==<br />
<br />
Get our hands on as many October '08 Esquire e-ink magazine [http://blog.makezine.com/archive/2008/09/esquire_eink_cover_hackin.html covers] as possible and rewire them into tiles of one big low-power display. (PY's idea originally. [[User:Elgreengeeto | -elgreengeeto ]]). Or, alternatively, just try to get some e-ink bulk from China and make an even cooler low-power display.<br />
<br />
<br />
==Transit status information==<br />
<br />
I've written something that uses [http://www.bart.gov/schedules/developers/etas.aspx] together with Festival to give announcements about BART trains approaching 16th Street. I intend on setting this up with a cron job to run around the time of the scheduled last trains every night (and maybe the first train in the morning if we think people may frequently stay until around 4:00 a.m.!), using the music server once it's stable. To avoid annoying people this should probably not be configured to make regular announcements at other times. Two extensions to make this more useful: (1) if we can get or make a USB-to-buttons/switches or parallel-port-to-buttons/switches adapter, we can have a big button somewhere that causes an announcement to occur (for use when people are thinking of catching BART and want to know when it's coming). (2) If we can get a big scrolling LED sign with computer control, we can have it constantly display train status -- as well as Muni bus announcements with data from [http://www.nextbus.com/ NextBus], perhaps using a library to get it.

==T-shirt printer==<br />
<br />
I'm still looking into the best way to do it, but some sort of t-shirt printer would be fun and useful. Seems that direct to cloth ink-jet techniques don't look as good as silk screening, but old-fashioned silk-screen is hella old-fashioned. Maybe some way to achieve silk screening results but with only limited human-interference? I'm thinking that proceeds from über-fashionable Noisebridge t-shirt sales would eventually off-set costs of this project. [[User:elgreengeeto|elgreengeeto]] 16:32, 10 October 2008 (PDT)<br />
