So this thread is kind of split into two parts, but I figured it’s better than making two threads. Anyways, let’s get down to business…
Stepper Motor Controller:
I’m looking to either purchase or [preferably] build a stepper motor controller. At this point in time, I was looking at purchasing THIS; I’ve heard great reviews, and it’s $80, a lot less than other controllers I’ve seen out there. Not too keen on the single board approach, but the lower price is worth it in my opinion. Obviously anything this price or lower will be considered. If it’s a modular approach (buying 3 drivers, then attaching them to a breakout board) then don’t worry about the breakout board; I have a schematic for an awesome one already. So anyways, in a nutshell, purchasing budget = $80 or [preferably] less.
This seems like a good time, so I’ll throw out the specs of the motor; I’m looking at two motors, but both at 6-wire Unipolar motors:
Motor 1: 6.2V, 1A/Phase, 4 Phase
Motor 2: 3.6V, 2A/Phase, 2 Phase
Anyways, on to to topic of building. I’d like for there to be detailed schematics, as I’ve built very few electronics but seems to be getting the hang of it quickly. Anyways, I’d prefer for it to have microstepping, but if we can get something that works nicely with full stepping only for nice and cheap, that will work just fine for now Again, if a breakout board is required, I’ve got that covered. Budget for building one would preferably be a tad less than buying, so let’s say <$70.
If I missed any info lemme know, and thanks for the help in advance!
Next up, I need either 1 servo controller capable of controlling 12 servos simultaneously, or 2 controllers capable of controlling 6 each. I would greatly prefer to build these over buying, but if the price is right, I’m willing to go that route. I need these to be as quick and precise as possible, while being as inexpensive as possible. I’d also prefer for them to be as small as possible! My main microcontroller for the project is an ARM Cortex M3, so I’ve got a fair bit of processing power. Lemme know what you guy’s have!
Also, if there’s anything you feel I should research to help in my understanding of either of these topics, and will help me eventually design these things myself, just list them off and I’ll gladly Google them:)
Thanks a lot,
