HOn30 Baldwin

So, the leads from the rails are hooked to the capacitor. It is then connected to the decoder? Sorry I am not an electronics guru. Does the capacitor emit heat?

It's more complicated. The decoder contains a current limiting charge circuit for the capacitor, which also limits the voltage.

Thanks for sharing. Any advise on making a new chassis for one of these engines. The original chassis for mine broke in 3.

Nice! Ive got one now that im trying to get running again, how do you get the shell off of the frame on these?

[NVanWendy]

@mattgin There's a screw on top, right in the middle of the saddle tank!

Great engineering! I always liked the AHM HOn30 stuff. It looked better than anything. It cool to see one running that well. What capacitor value did you use?

[stickboytlr]

Very clever, good work!

[NVanWendy]

So did you just solder the capacitor in-line with the motor feed, or is other circuitry involved? I've often wondered about the possibilities of using a cap' like this, and clearly, yours works beautifully!

A bit more complicated.. I designed my own decoder (HW and SW) which runs off 3V. The capacitor is charged to this voltage. When the loco is commanded to stop and does not see a DCC signal, it begins to crawl until it sees power again. The decoder also features EMF control. This is not a commercial product, just for fun.

Hmm. I suspected that. I'll have to talk to my local electronics store one day about the idea and see what's involved in having a little bit of stored power for a straight DC motor system.

Thanks - and that is spectacular work!

Superb. Lenz what decoder?

[md95129]

The decoder is my own design (hardware+software). It is based on a Silabs C8051F300 microcontroller.

excelente!!!!

Amazing! This is really smooth running!
