Class : Apprenti Posts : 5 Registered on : 10/03/2009 Off line	I have recently bought 10 sfh485p leds from Seeedstudio and some 1/4W 22 ohm 5% Carbon Comp Resistors. My plan is to use USB to power the leds. So now I have it all wired up, but when I plug it in I don't see any light from the headset and the wii remote is not picking up any light source as well. I need some guidance here on how to troubleshoot this. Is there a quick and dirty setup I can use just to test if I can get one LED to light and be recognized?

Also, unrelated to your problem, but in general as well: Did you make sure to fuse your connection so you don't have the potential to fry your motherboard?

Class : Apprenti Posts : 5 Registered on : 10/03/2009 Off line	Well I consider myself fairly inexperienced. Yes, I verified the positive and negative leads before I made my connections. No I hadn't fused my USB connection. I was saving that for last after I had everything else working. For now I would be happy just to get one LED working in any power/wiring configuration.

It is on the flat side. A quick test if your led is working, use your digital camera / preview screen. A quick test if your Wii / Freetrack is working with IR-led, use a remote control, point it at your Wiimote and press a button and move it. Select one point model in Freetrack.

Class : Apprenti Posts : 5 Registered on : 10/03/2009 Off line	Thanks benmeijer testing with the digital camera worked great. I now have a working model and want to incorporate the PTC fuse in my USB cable. But I am not sure how exactly it should be connected. To me it makes sense to put it in line on the negative side. Can anyone provide some guidance?
