This is still a work in progress.
I’m having some issues with the gear. It seems my printer can’t print it perfectly round or maintain consistent backlash, so the motor struggles at specific points in a rotation. Printing the big gear more slowly helped, but didn’t completely solve the problem.
It works, and you only notice it because the motor gets louder and the current goes up, but it’s still driving me crazy. For a system without any bearings, it rotates quite easily and smoothly for most of the rotation. It can definitely turn a couple of kilograms.
All you need to get it turning is a single NiMH cell and a switch, really. But I’ve added speed control with a touch sensor, a Digispark, and a 2N2222, as well as a Li-ion battery with a charging module. However, I’m going to change the charging port for the next version.
Since there are already many turntables available, I would only add instructions and more information, like the Arduino code for speed control, if there’s a demand for it (since this is actually a procrastination project I did to avoid finishing other, more ambitious projects).
Oh yeah, and it's kind of loud, but I will only use it to take pictures and videos of things, so it doesn't matter.
