Marx directional lighting
A lot of Marx collectors have modeled Ho DC trains before and have fitted directional lighting to their engines on DC this is as easy 2 diodes however on AC this is not possible due to the alternating above and below 0 volts. So as I wanted to fit directional lighting to one of my engines I came up with this simple circuit.
Below is the timetable of fitting the circuit to an engine.
10:00pm Plugged in soldering iron and pulled apart engine
10:05pm Cleaned up armature while soldering iron heated up.
10:10pm Realize soldering iron is not turned on. Turn on and go make a cup of coffee.
10:15pm Soldered new wires to each end of the coil and re diverted the other wiring.
10:20pm Reassemble the engine.
11:00pm Finally get the wheels back on there must be an easier way.
11:05pm Place engine on track and apply power. Realized that not all the wiring is diverted, as engine doesn't move.
11:10pm Dismantle engine again.
11:15pm Redirect ALL the wires needed.
11:20pm Reassemble the engine.
12:00pm Finally get the wheels back on again.
12:05pm Place engine on track and apply power. Engine runs this time and light goes, unfortunately it goes all the time. Try to work out what went wrong.
12:45pm Realize there's a fatal flaw in the design and go to bed.
So as you can see I tried a design but it looks like its back to the drawing board for me.
