Sensebridge Meeting March 29, 2009 ==People== Eric, Skory, Mike, Peter, Matt, Rachel Denise, Bat, Ted, Nag, Nana, Nabil, Sarah, David, Mikolaj, Daniela, Mike ==Introductions== * Eric - compass vibro anklet with Skory, engineer, works on sensors * Skory - compass vibro anklet * Mike - remotely operated vehicle telemetry stuff * Peter - here to see what people are working on * Matt - wants to work on "eyes on the back of the back" * Rachel - working on vest with distance sensors in the back - to sense through touch what is behind you. Wants more help! Progress so far: thought work, testing of motors * Denise - UCSC, works on device which goes on glasses and clarifies consonant noises for Deaf people * Bat - no tech background, botanist, visiting friends here * Ted - has been working on compass belt project * Nag - from Seattle, hangs out with PNA hackbot (?) people - also working on compass belt, wants GPS input to them - two belts, one points to house, one to mountain, so can "triangulate" location. * Nana - happened to be here. Did map making. * Nabil - she's here because we're all really cool :-). Also, likes to make her brain do cool stuff. * Sarah - a rocket scientist. Designs space robots for a living. * David - made Arduino powered breathalizer - but tells you how much more to drink for desired level :-) * Mikolaj - has thing which shines light in north direction. He got this group started. * Daniela - artist. Interactive art, with sensors, especially things which sense the invisible. * Mike - starting new "science & engineering huddle on Thursdays at 7pm", basic material design things, ground loop issues, etc. Design from concept to finished product. ==Show & Tell== * Choker - show your heart beat * Ring - show noise levels / wifi levels with lights * Persistence of vision fan ** persistence of vision weed wacker *Demo of compass anklet ** troubles with 2-axis magnetometer ** signal filtering / using an accelerometer ** maybe position just below the knee? * Stepper Motor battery charger, powers light, totally silent ("science of vision flashlight"), also has field power supply *Infrared goggles - your eyes ARE sensitive to infrared, so if you block everything else your eyes will adapt (if things are really bright in IR - need to be outside) ==Batteries== * Eric will come around with group order form for sparkfun batteries later ** orders from: Eric (assortment+charger), Skory (2+charger), Rachel (2+charger), Mikolaj (2) <pre> ORDER SUMMARY: Status Product Qty Total ------------------------------------------------------------------------------------------------------------- Item in Box PRT-00731 Polymer Lithium Ion Batteries - 100mAh 2 $13.90 Item in Box PRT-00726 LiPoly Charger - Single Cell 3.7-7V Input 3 $50.85 Item in Box PRT-00339 Polymer Lithium Ion Batteries - 1100mAh 10 $107.60 Item in Box PRT-00341 Polymer Lithium Ion Batteries - 860mAh 1 $8.95 ------------------------------------------------------------------------------------------------------------- Subtotal $181.30 Shipping and Handling + $11.35 ----------------------------------------------------- Grand Total: $192.65 Skory + Rachel owe 2*10.76+16.95+11.35/4 = $41.31 Mikolaj owe 2*10.76 + 11.35/4 = $24.36 </pre> * could also use AAA batts - for convenient replacement ==Cybernetics Meetup== * 54 people have expressed interest on meeting.com for "cybernetics" * we are a subset of that, we're trying to build stuff - if you're into that, then show up. Eric will draft something and send it to meetup. ==Daniela's project== Daniela has a project - zero gee. Uses "maximis B", a graphical programming language. Building a "crystal ball", which will float, and use magnetic sensors. It will go in parabolic flights. She's in a group of 20 artists all working with sensors. The crystal ball will create sculptures in software - and those sculptures will eventually be built. Recommendation: play with ferrofluid. ==Eyes in the back of the back== * Rachel plans to cut up a T-shirt * plans to use motors/vibrators as the display * 1 dimension: just a line across your back, which responds to stuff "behind" it (need narrow sensors) * discussion of doppler radar (pound30 sensors, a few years ago), LIDAR, ultrasonic sensors, etc. ==Armature Ideas== * Umbrellas? - google maps inside your umbrella * Displays inside your shoes? ** top of foot ** things in the holes in Crocs (there are already plastic things which pop in and out) ** Stripper Boots - heels have lots of room for stuff! *** goddess project has done this - minimal websurfing?!? * Piercing to hold electronics * Off the back of glasses * Something built into a phone to help Aspbergers with facial recognition * Build something into a cast? ==Discussion on compass armature== * much discussion of the proper place to wear the vibro-compass ** corset ** anklet ** bracket ** belt * design to be resized at least a little - then quite flexible in actual location...
