Hi Paul

Very neat & sooooper compact wiring on your DIY 'Keep-Alive' !

(yes, perhaps smaller resistors next time !)

Well worth 'doing it oneself'.

Those Million $$$ super-capacitors, from expensive RS, Digikey & Mouser etc. ...

... are just pennies, from China on eBay.

Those commercial 'Keep-Alives' must have gold-bars inside them !! :shocked:

Si.

1.5 Farads should be a great keep-alive storage, mine are only 1 Farad so you should get 50% more :brill:

Good price too.

I got all my components from an online electronics supplier here.

Still a little more than yours on eBay.

Paul

Forgot to set the DC mode off.

This is what happens when you remove power from the track.

Funny

Quite logical.

When CV29 bit2 is set,
the decoder checks the input for DC-level,
when there is no DCC signal.

As the DC input is zero,
the motor power signal is set to zero accordingly,
and stops the loco.

Have you ever added a Keep-Alive to a non-sound Bachmann Porter?
