I really want these to equip my MU (Silverliner IIIs, etc) cars that only operate with a single power truck, but they are also VERY expensive.
I'm kinda surprised I can't just make a small circuit with a capacitor to store power for a few bucks and 10 minutes with a soldering iron.
I tinkered with a circuit simulation program I have, and it looks like I have a winner (will have to get a screenshot some how), but i wonder if this would mess with the DCC signal, since the capacitor seems to want to release every once in a while (in fact, i needed to wire in a diode to prevent a "negative" current). Still, when i open the switch, the simulated LED stays on for a little while.
Are there maybe not capacitors available that are small enough or store enough power to run a locomotive available to the average modeler?
