Yay
I just tried out a new webcam lens today, and I'm happy to say it's way brighter now. I no longer need to keep the gain cranked on the highest possible setting and the sensitivity is better. Turns out the lens I was using from my 'Infrared Webcam' still had an IR filter coating on it.
Images are now like this even for light touching
It's bright enough now that fingerprint grease smudges show up enough to be detected. I'm gonna need to work on some adaptive background removal soon.

strange, on your site you posted IRC server freenode.irc.net and channel #ftir, are you sure ? cause freenode.irc.net is bitlbee IRC server and thats the IM gateway. maybe irc.freenode.net server ? strange i can't catch up you on freenode irc.
maybe better to create a mailing list? for example on google groups
Sorry, it is irc.freenode.net . I corrected the page. I'm usually around from 5:30 EST - 10:00 EST.
we also trying to play with ftir touchscreen, and a little bit stuck with hardware. i hope so that soon we will be finished with HW and join you with SW development
maybe it's good idea to create mailing list? because between us is big time difference, so discuss by emails better
if you don't mind, send me your emails to nikolajus at gmail dot com and ill create mailing list on google groups for us
We already have a private mailing list - I'll see about getting you added on. For now, you can email any questions to me at admin [at] whitenoiseaudio dot com.
Awesome image. Now the question is, would it have been good enough with the original number of LEDs ;-)
dzhibas, I've sent you an invite to the Touchlib mailing list ...
sweet i have finally got my gear together , two sheets on 3mm perspex and a A1 sheet of tracing paper , i am gonna sandwitch the paper between the perspex , for my initial tests the paper dosnt bother the ftir and is very bright with the projector , hopefully i can get time to cut the sheets up and get some pics together
cool stuff ray - I've used tracing paper as a diffuser and it does seem to work well.
