Gravel screener build

I've got to slow this down. its way to fast. even with a geared motor.

what can I use as a speed control?

Reduce your voltage

That was the first thing I thought of. It runs that fast on 4.8 volts 4 AA battery's. Is there a cheap manual speed control out there. Or?

What you need is something like this. All kinds to choose from that are rated at various amperage and voltages, with or without reversing switch. Ive got a few of them and they work great and produce very little heat compared to a variable carbon pile resistor.

Looks like you made a "slinger screener"! Seriously though it looks great and when you get the speed right it will be awesome!

Where am I now?

So I lowered the voltage which lowered the speed of the drum, but it lowered the amps as well. Which does not allow the geared motor to turn a heavy load.
It tense to struggle. Now I figure I'm going to need a geared motor slower/stronger than the one I'm using now. I figure a 540 can size 37mm gear motor at about 35 to 60 rpm at the shaft. And a proven speed control to save me time and head ache(using Mario's recommendation). And a universal coupling. Then some form of way to get DC current to the electronics without using batteries. I will still have receptacle's to use batteries when no power is available.
So until I get some parts in I'm only going to be able to work on the cosmetic aspect of it. I really don't even know what its supposed to look like LOL. I need to see one in person or get some up close pics. But GOOGLE has been of great help but not enough close detail. I'm not looking to make it true to scale but it take time to get the parts from china most times. Might as well jazz it up a little.
I was fiddling around with it and made this video.
