FreeTrack Forum

FYI, I had a few more issues and managed to figure them out myself. Just wanted to post in case anyone stumbles across this in the future.

I found when I was turning my head I would lose tracking and I noticed there were numerous little red crosses over the LED. I changed the min diameter to 6 and now it does not recognise all those other dots that were screwing with the tracking.

I also actually measured my device and input the measurements. As my device was non-standard size this made a huge difference.

Thank you very much for making a great program and thanks again to those who helped me. I have just finished playing company of heroes single player campaign hands-free with this plus a voice recognition program called Tazti.

You're welcome.

This is a real challenge, good job!

I'm in a very similar situation so I'll just add on here.

I'm starting out with the same LED's as the OP for a USB build.

Want to add a PTC for MB protection and this is the closest one I can find available to me:

Is that adaquate? Also following the maths above with it's resistance being about 7.5ohms I need another 20ohms worth in my resistor (aprox.) and while I have several 1/4w 5% carbon film resistors lying around the house from projects on musical equipment I don't have anything quite that high. Is it okay to stack several smaller resistors in series (likes two 8.2ohm and a 3.3ohm) to get in the right ballpark or will that cause other problems?

Thanks in advance.

Edit: 10 days no reply? I don't like to double post but should I maybe start a new thread?
