I’m just re-furbishing a model jeep, can’t remember what it’s called, it was a popular build constructed from a sheet of 8×4 ply and powered by a windscreen wiper motor.
My Dad built this one for my kids, but he made a number of “upgrades”. One is that the drive is a Sinclair C5 motor driving one rear wheel via a commercial reduction box + chain.
Full speed is about walking speed and at the minute power is switched to the motor by a micro switch under the “accelerator”. (Hi current relay near the motor).
I did think about adding a speed controller so that the power is applied in a more controlled way, but given the low top speed it seems overkill.
Is there some simple electronics available that would simply ramp up the power when the accelerator is pressed, as I see no need for manual speed control?
TIA
