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

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.

cool stuff ray - I've used tracing paper as a diffuser and it does seem to work well.
