Devlog 4:
-Think I have figured out what to do with the motor
-Searched for a new low-power BLDC motor driver board (what gives power and controls the motor, “kinda”).
Extra:
- I think I know how to prevent the electric field caused by the motor and the inconsistent power-draw from interfering with the audio components.
-Since the motor uses very low power, the fields shouldn’t be as strong as normal. And because of that, some copper-tape wrapped around the motor (with some space between) and then connected to ground should be enough to absorb the electric fields (maybe not the right term but who cares).
And to neutralize the inconsistent power-draw, I can just use some resistors (hopefully) between the motor and power-module, and then between the motor and ground.
I’ll do a bit more research to be sure. - The old motor driver I found apparently needed 8-30V. Which is quite a lot for what I’m making. So after roughly 30 min of searching I finally found the “SparkFun Brushless Motor Driver - 3-Phase (TMC6300)” on their own website. It’s ~18$ + shipping
(not that bad), but I really can’t find another one that would work for this specific use case. Searched though AliExpress but just found ones that requiered 5-30V and something else that’s slightly inappropriate (and completely unrelated) instead
Here is the module I found:
