Hey all… so I’m working with two other students on a project we call TouchABLE.
I’m attaching pics of my IR illuminator boards (we milled them out on a PCB mill). There is an RJ45 connector on them so the can be removed easily / changed around at will… there is also a hard wired connection. We decided to put one resister per LED as if one goes we don’t want a chain to go, nor do we want to supply over current to the others on that chain either.
As the title says the setup is a DI type, and we have only done tests on this size cabinet so far without the box, which is what we are doing now.
We haven’t faced it yet, but should have that done by tomorrow. Looking at the box, the glass sits out about 1/2” from the face of the box so it looks like its floating.
Parts list:
Projector: BenQ MP771 (amazing distance!)
Camera: Fire-i BW
Lens: 2.1mm (Wide) w/no ir filter (obviously)
LED: Osram SFH485 (would like to try the gold dragons tho)
RES: CFR-50JB-39R Yageo from digikey.com
Glass: VIKA GLASHOLM ~ Tempered coffee table glass from Ikea (150mm x 80mm)
Total cost including lumber so far: $1,969.01
Suggestions / comments welcome!
Keep up the good work!
