[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.

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

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

tightly focused viewing angle of 8° or less—could, in theory, cause
temporary blindness, and so are classified as "Class

states: "According to federal standards, LEDs are not hazardous except for
