Hi Stan,
The new MP3 players arrived early. I hooked them up per your instructions and every thing works as you said except the 1uf cap does not eliminate the pop when my player starts up. Will a larger value cap help??
As to posting pics, my friend is on vacation, and we need to come up with the optimum height for the sensors (depends on different rolling stock configurations so as to always get a reflection--even with a built-in delay) before he designs an enclosure. He does have a completed crossing gate, and I will post pics and a vid when he returns.
