least in part) independent of the rails. My own interest is not in
enabling KAOS power for DCC, but in rail-mounted animation.
The solution for loco control is a relatively simple, low-cost
($3.60) radio link to the loco, using an RFM12B transceiver
module (transmitter/receiver). This is not traditional RC con-
trol, even though traditional RC control could be used here at
greater cost, and using more space in the loco. This scheme is
more like a 2-way serial data link via radio. The RFM12B is con-
trolled with a small Arduino.
The combination of the RFM12B mounted on the back of a
small Arduino, nearly in the form factor of an Arduino Pro-Mini,
is available as a Moteino from Low Power Lab
This saves even more space, and comes with
its own program sketch library including working examples. As I
recommend quite often, I copied a basic example and edited it
for use in a small, 9-volt battery-operated remote control. The
example library will support 255 channel IDs, allowing many
different locos to be independently addressed.
