| The pictures above are of home made 3
color LED searchlight signals designed and built by Gordon
Sherret. The materials consist primarily of brass tubing,
0.010" sheet styrene, bi color LEDs, magnet wire and male
printed circuit board headers (used as a base to fasten the signal
mast and to provide electrical connections for the LEDs). The
signal driver circuits are a slight variation of the circuit
designed by Rich Weyand of TracTronics |
| Thank you to those who have expressed
an interest in my signals during the SuperTrains 2005 show in
Calgary, Alberta. As promised, here is the order form to purchase signals featured
at the show. |
