The Wood Track

I went with Trackmate instead of building all my electronics this time.

The light bridge and the sensors, I bought the 4 lane solution and resized it to the width I needed with only 3 LEDs

Pyramid power supply for now, 6-15V 25 Amps. Will be replaced soon by my Trackmate supply 0-30V, 20 Amps currently on loan
BK precision power supply for all accessories: 2x 0-30V, 3 Amps plus 5V/5Amps
Obviously some clean-up work to do for the wires

Trackmate interface board for sensors and relays, serial (9 pin) connector with a serial-USB adaptor into the laptop
