Hello,
Right now, I'm doing research for a specialized app to let consumers
validate products that can be used to treat insomnia. Specifically, I'm
working on a smartphone app that can act like a light detector for light in
a narrow band around 470 nanometers. This is the frequency that has been
shown to suppress melatonin secretion by the pineal gland.
There are specialty products for avoiding late night 470 nanometer light
exposure (light bulbs, screen overlays, glasses) but these are often very
overpriced, and there is no convenient way to validate them. There are also
"ordinary" products that serve the same purpose, but there is no good way
for people to accurately test them. Currently, people can use a CD or DVD
as an ad-hoc diffraction grating and look at the resulting spectrum, but
even this isn't quite good enough. I've bought a narrow bandpass filter for
470nm light, and even products that have a spectrum that "looks good" (very
little blue) can have hot-spots that leak large amounts of 470nm light, and
it doesn't take much to suppress melatonin. (As low as 0.5 lux for
prolonged exposures.)
Looking generally at spectral response curves for digital cameras, it
should be possible to "synthesize" a narrow band detector by taking the
blue channel response and subtracting the red channel value.
http://www.maxmax.com/images/Cameras/Technical/NikonD200_SpectralResponse.j…
This should effectively produce a "synthetic" instrument that has a
spectral response curve that would be the camera's blue response, minus its
red response. Even more helpful, the user should be able to view a
synthesized narrowband image of the product, to be able to spot leaks and
hot spots.
What I need: I would like help in scientifically measuring the spectral
response curve of the "synthetic instrument." I already have a (tiny) 470nm
filter from Thorlabs, and I'm already aware of Public Lab's DIY
spectroscope. I would like to use more accurate equipment, however. It is
important that I can provide accurate information about the performance of
the app and use rigorous procedures for measurement so that users know they
can rely on the instrument.
Does anyone have the expertise and access to equipment to help me out?

hey all,
do any of you know of any useful tools for facilitating a civic debate
(something like a presidential debate) online?
http://backchan.nl/ would be good for submitting q's...but backchan.nl +
google hangouts seems...not the best? any tips would be helpful.

just a reminder.

Subject: [sudo-discuss] [consensus] Nominations for Board of Directors
To: sudo-discuss <sudo-discuss(a)lists.sudoroom.org>
Or, alternatively as suggested last night, Board of Those With Little Power
and Great Responsibility (or something to that effect :)
The following is a list of those who've accepted nomination to the board,
and those who've been nominated but have yet to accept or decline:
- Accepted: Max, Jenny, Naomi, Anca, Hol, Vicky [tentative], Marc, Matt,
Luciano, Troy
- Nominated: Rhodey, Marina, Liberty [tentative accept], JC, Len, Romy,
Ryan B, Julio, Vian, Shake, Mitch, Brendan, Morten, Faust
Please reply to this thread publicly or privately if you've been nominated
but have yet to accept or decline.
*At next week's meeting, we will go through and consent on each nominee.
Those participating via the mailing list have one week to block any of the
current nominations.*
What's required of a board member?
- the risks, not many risks if you are not paid
- the only thing we have to worry about is if sudo room doesn't pay
taxes then the treasurer will be liable for taxes
- also board has responsibility to send in a document once a year to
sacramento
- not liable if sudo room goes into debt (except treasurer)

not sure if this is the right list for this, but thought it should be
forwarded. SELC as you guys know is awesome, they've helped us out at Bay
Area Community Exchange as well.
thanks!

Hi Friends,
The Sustainable Economies Law Center <http://theselc.org/> is participating
in one of those fundraising campaigns where we'll get $20,000 from
Sungevity<http://www.sungevity.org/gives-back> if
we can get enough people to vote for us. I don't love this style of
fundraising, but I'm highly motivated by this one. The $20,000 will
determine whether or not we get to keep my wonderful coworker, Caroline
Lee, at SELC. She just graduated from law school and she is brilliant. If
she stays at SELC, she'll be developing model legal structures for
cooperatively-owned and community-owned renewable energy projects. If you
can support this by voting, I'd be so grateful!
*It takes 10 seconds to vote. Click
here: http://www.sungevity.org/gives-back
<http://www.sungevity.org/gives-back>*
FYI, you need to enter your email address to vote, but if you'd rather not
be on Sungevity's email list, you can always click "unsubscribe" in any
email they send you. I read their "terms and conditions" to make sure. :o)
Thank you so much!

Hey everyone!
I would like to improve the user experience of our Wordpress and Wiki. I'm
particularly interested in the latter, and making it more intuitively
structured, poetic (in the literary discourse sense of the word (
https://en.wikipedia.org/wiki/Poetics)), and UPDATED! I'm free to work on
it either Tuesday or Wednesday, daytime, at SR. (I'd also be into working
in the evening, but only if I can get a ride in a car, as I try to
absolutely avoid biking in the dark with my laptop.)
If you're interested in joining, please respond to the list with preferred
days/times.

I'd go but I'm on the east coats. If someone attends could you report back?
