This seems like a stretch, but what would it take to make a wireless mouse useable as a transmitter and receiver for an engine?
Seems like there’s enough functions on one that it would be sufficient:
Left mouse button - forward
Right mouse button - reverse
Scroll wheel - speed
Not knowing what voltage or type of signal is coming out of the tiny receiver I would guess some kind of circuitry would be needed for it to plug into to convert the button presses into actions.
Wireless mouses can be found for $9.
Just a thought, probably missing a simple reason why it can’t be done.

The simple USB receiver needs some amount of driver software in the background- something e.g. an Arduino cannot handle easily, but a RaSPi can do it, in fact it is all in the Linux that runs it.

Ahhh...a mouse running a train! A novel idea for sure. It should work, see if it can be done.

Woodie

I'll have to check out the Raspberry Pi3, my memory on electronics theory and how stuff works has faded since 1980...I guess Goggle will be my friend!

If memory serves me correctly the chip used in the mouse is close to what David uses in his Deltang Receivers & Transmitters.

I guess I need to figure out how to get from the chip (receiver) to the motor!:old dude:

Sounds like you'll need an H-bridge motor drive chip.

Actually it is a little more than that, but not that much. Just a µC to handle the incoming serial USB data and the RF management, make pwm and digital outputs of it, all in all something like a DT RX:bg:

This chip is used in some wireless mice: http://www.cypress.com/documentation/datasheets/cyrf6936-wirelessusbtm-lp-24-ghz-radio-soc
