Have you considered using a pair of relays and a timer? I've used two 5 pin relays to reverse the direction of current successfully and i reckon it wouldn't be difficult to use some sort of timer to switch the relays.
It occurs to me the alien could be from one of the universes that has already faded. . Knowing it's inevitable the same will happen in this universe unless the artifact can be used to somehow keep this universe attached to the wave? Coffee fueled btw
Well i just went by the info on the ad itself. I added a cooling fan to be safe and crossed my fingers! I got lucky with the 4 motors seeming to cancel each others electrical noise! I put the car on crates and when I put load on two wheels the other two just slowed to match and there was barely...
These are pics of the sort of motors and reduction gears I'm using
I have removed the inductors and capacitors from the ones I installed, and now I am realising what they do! What sort of things should I consider using caps and inductors?
so you can see what I have done with the relays here is a circuit diagram I did crudely with Paint.
This part at least works perfectly, just the pot wasn't useful to vary the supply.
The PWM module claims 480W at 12V, I expect to peak around 300 or so.
My existing relays are wired to deliver a variable input in forward or reverse. I tried using a pot to vary the power but i had no start up power except on full. I think this unit will deliver variable speed to the motors.
