The concept of Keep Alives or Stay Alives (SA) has taken my interest. I had looked into SAs about 12 months ago but at that time, the super caps or the ultra caps were just too big to fit in any one my locos.
At that time I did order some 1F caps but then lost interest and shelved the caps, but luckly I had found these caps so I built a quick test circuit.
Now, on Loksound v5 decoders, they have made it quite easy to connect your own home built SA. After doing some research, I took the plunge and decided to carefully solder a couple of wires to the pads and then connect these to the home built stay alive circuit that was built using the 1F caps.
With 10VAC coming out of the track, I was quite relieved to see the ciruict actually working!

Now I am waiting for smaller ultra caps to arrive so I can built a permanent circuit to fit inside this locomotive. Then will try to do the same to the others.
