More progress:

I just ordered samples of the ADS1110 from Texas Instruments. For the other missing part I contacted Carson Reynolds and he told me I could use a zener diode instead, or anything that regulates the voltage to 2.5V. So i'll figure out what's easier and cheaper and get that going.

Anyway, TI estimated shipment by Sunday so I hope by the end of next week I'll be able to start work on the GSR amplifier. For now i have everything i need for the LPT connector, and I'm starting work on 2 of them.



Any ideas for the name we're giving to this baby?

(edited: actually, TI just shipped the 4 A/D Converters just a few hours ago, and they meant i'd GET THEM by Sunday, which is way way cool. Maybe by the end of next week I could ship Placebo a completed copy of the device and see if he can come up with something)
