First, love the new forum!
Second, in developing a plug-n-race solution for lane chipping, I'm wondering if placing a transmitting IR LED alongside the receiving sensor (assuming the receiving is in the track) would allow an analog car passing over (perhaps with reflective tape beneath the chassis) to trigger the CU. Anyone ever attempt that?

I'm toying with the idea of constructing an Arduino solution using hall effect sensors, but certainly magless cars may be an issue as I'm not confident without testing that a motor alone would trip a hall switch. The above may be an alternate solution for me to investigate (or not).
Thanks for any input.
