Class : Apprenti Posts : 3 Registered on : 10/09/2008 Off line	Hi I plan to build a 3 LED (SFH485P) clip setup, with the Microsoft VX1000 webcam, that is powered by an USB port (yes, I'm aware of the danger to damage the mainboard). I'm getting help from a Professional when building the circuit, so don't worry. I would like to work with an unmodified webcam, that I can still use the cam for other purposes, without having to re-attach the IR-filter. So I will try to power the LED's with 50 mA each, in a serial circuit. This is what the Wizard said: http://img370.imageshack.us/my.php?image=sfh485pjpgxk5.jpg Is this correct so far? I now need to know what ressistance to use? 10Ohm 0.25Watt (1/4Watt)? And for safety a PTC Fuse with a 0.2A current cutoff? Am I right so far? Thank you for your assistance.
