Hi to all. I'm a new user (Italian) of this web site, and I want try to build a FreeTrack sistem (3 points cap).
I find the material that I need for the operation, but I've still two questions:
1 - I try various shops for buy the SFH485P, but without success. Finally I've bought 3 normal red led (5mm). I red that I can use it, but first I've to fix it by filing their lens tips down flat for obtain a wide angle Led. Like the picture:
