I just built a very wonky prototype of a bracelet sensor system. Well, I put together the electronics and the code -- four other people did the rest.

The idea is that it will take biometric responses (pulse, moisture on skin) to light up the bracelet at certain colors and speeds. It would be meant for children on the autism spectrum and their parents: the parent can see the response and get a better idea how the child is reacting; the child can learn to associate the favorite colors to a parent's emotional state.

We won a competition on Sunday. Now we have to make the prototype a little less cargo-cult in time for Wearable Tech LA on July 17th.

I'm a little stressed -- I didn't think we would win. We hit the right chords with the judges, one of whom was from Intel and another from a VC angel firm. Now we have to get this thing to survive a more scrutinizing panel.

...but it's been a rush! I am coding in C and getting responses!

I had a pie-in-the-sky idea to make a prototype by the end of the year unrelated to this: it would take phono line (millivoltage, pre-RIAA leveling) as input and put MP3, AAC, OGG or flac on an SD card. Now I have a lot less fear of not figuring out the ADC part.
