Hello Howard,

Great project! i came across this from finding your transponder design thread. Now i have went through alot of it skip some pages, im no electrical engineer but i am interested in this as a low cost system for our club, we are using the Robitronics but its not very accurate and its difficult to get people to spend $45 for that transponder on top of the MyLaps RC4 they already have. We certainly cant afford a RC4 decoder.

So if i can build something affordable and hand out transponders for free or for very little charge then we can hold more races and even invite others.

1. From what i understand you have a working decoder with transponders?
2. Do you have an final plans with a list of materials? instructions?
3. Which timing software is compatible with your decoder? We use Flip Side Racing (opensource) i think that fits well with your project!

is anyone using this at a track sucessfully ?

thanks!
