[Noisebridge-discuss] Think it would be cool to start a current-hax at noisebridge.net list

 I think this would be an awesome start for people to send simple emails
about current projects that they are working on and would like to
share/discuss at the Noisebridge Hackerspace. It think it would also be a
great catalyst for collaboration on projects as well. They could be tweet
style emails such as.


To: currently-haxing at noisebridge.net

Subject:y Hacking a Raspberry pi to control three different led strips at
once.

Body: Working toward creating awesome led lighting for the HaXiTorium to
use, instead of those florescent, evil, "I am a mouse in a
laboratory.'''Feeling type.'" Tubes.

My motivation to do this is because LEDs are freaking awesome, and because
of the health dangers and risks for being under florescent tubes
constantly; they suppress meletonin... What?!?

I have already also installed one strip of led lighting and it barely
suffices for typing at a terminal, Other then that reading a book would be
rather challenging for one with not the greatest of eyes sight at night.
And the solution... More LED strips. :-P

Other then that I think it once again would be cool to have a
current-hax at noisebridge.net list (or something around that name-make it
current..?)

Feel free to reply to this email and collaborate with me about this
project. This could be a possible way for new and regularZ people to
introduce themselves and find others interested people to collaborate on
their projects; something that has been somewhat of a journey through the
NB environment lately (and quite possibily in the past).

IMHO currently-haxing at noisebridge.net >= project page on NB.WIKI.

P.S. As for all of the recent drama, I think that Noisebridge as a
hackerspace withing a Hacker Community at Large is doing a great job at
working through the issues that have recently transpired.

Cheers again.

"RAYCing around the space, while working on some led-blinking Light
Emitting Diodes to set into the space. For better illumination for the
human RAYC because these florescent lights seem to cause head aches and eye
strains that are really not good for this place. I am not ripping them
out-just adding some LEDs because the following quotes may be worth the
read. "

"The normally unnoticeable 100–120 Hz flicker from fluorescent tubes
powered by electromagnetic ballasts are associated with headaches and
eyestrain. Individuals with high flicker fusion
threshold<http://en.wikipedia.org/wiki/Flicker_fusion_threshold>are
particularly affected by electromagnetic ballasts: their EEG alpha
waves are markedly attenuated and they perform office tasks with greater
speed and decreased
accuracy.[10]<http://en.wikipedia.org/wiki/Fluorescent_lamps_and_health#cite_note-10>Ordinary
people have better reading performance using high frequency
(20 kHz – 60 kHz) electronic ballasts than electromagnetic ballasts,
although the effect was large only for the case of luminance
contrast.[11]<http://en.wikipedia.org/wiki/Fluorescent_lamps_and_health#cite_note-11>"

The vast majority of devices containing LEDs are "safe under all conditions
of normal use", and so are classified as "Class 1 LED product"/"LED Klasse
1". At present, only a few LEDs—extremely bright LEDs that also have a
tightly focused viewing angle of 8° or less—could, in theory, cause
temporary blindness, and so are classified as "Class
2".[106]<http://en.wikipedia.org/wiki/Light-emitting_diode#cite_note-106>The
Opinion of the French Agency for Food, Environmental and Occupational
Health & Safety (ANSES) of 2010, on the health issues concerning LEDs,
suggested banning public use of lamps which were in the moderate Risk Group
2, especially those with a high blue component in places frequented by
children.[107]<http://en.wikipedia.org/wiki/Light-emitting_diode#cite_note-107>In
general, laser
safety <http://en.wikipedia.org/wiki/Laser_safety> regulations—and the
"Class 1", "Class 2", etc. system—also apply to
LEDs.[108]<http://en.wikipedia.org/wiki/Light-emitting_diode#cite_note-108>

While LEDs have the advantage over fluorescent
lamps<http://en.wikipedia.org/wiki/Fluorescent_lamp>that they do not
contain
mercury <http://en.wikipedia.org/wiki/Mercury_%28element%29>, they may
contain other hazardous metals such as
lead<http://en.wikipedia.org/wiki/Lead>and
arsenic <http://en.wikipedia.org/wiki/Arsenic>. A study published in 2011
states: "According to federal standards, LEDs are not hazardous except for
low-intensity red LEDs, which leached Pb [lead] at levels exceeding
regulatory limits (186 mg/L; regulatory limit: 5). However, according to
California regulations, excessive levels of copper (up to 3892 mg/kg;
limit: 2500), lead (up to 8103 mg/kg; limit: 1000),
nickel<http://en.wikipedia.org/wiki/Nickel>(up to 4797 mg/kg; limit:
2000), or
silver <http://en.wikipedia.org/wiki/Silver> (up to 721 mg/kg; limit: 500)
render all except low-intensity yellow LEDs hazardous."[109]
