Hat design help (3d Scanner)

Mon Oct 16, 2017 11:53 am

Ok, this is going to get complicated

I'm building a FreeLSS 3d scanner and I'm struggling with the electronics. Basically, I need to design a board that can drive two 5V line lasers, and a 12V stepper (using a DRV8825 driver)

I've tried looking at the circuit boards on the freelss website, and cant get my head around them. Anyone who's better than me at this kind of stuff who can help? PCB design, was never my strong point, and since its for use at my local hack space, I'd rather make something that'll look a bit more professional if someone needs to fix it up at any point.

Obviously, this will need a 12V and 5V feed, although I'm hoping that using a 12>5v regulator means that I'll get away with only 1 power feed

any help would be much appreciated

--edit--
Forgot to mention, this is to attach to the pi, to run FreeLSS on the pi... just incase that wasnt obvious to anyone

Is there anyone at your hackspace who can help. My local one ran a few PCB design sessions and there are generally people who are very happy to share their knowledge.

quite possibly. I've not been able to get to any events at the moment, due to working funny hours (I deliver pizza, so I'm working when most people are socialising and attending fun hackspace sessions lol.

I've posted on our google groups to ask if anyone there can help me. Just thought i'd ask here too. as you guys are more familiar with the pi than the average hackspace member lol.

The freeLss scanner fits onto a protopi plate.
I would share mine but its half assembled and not had the time to work on it.

I cant say I'm supprised, its not an overly component heavy project as far as I can tell lol.

I've almost finished designing my own board to do it. But first, I've got to put it all on a bread board (once they all arrive) and test it out. IF it works, then I'm going to order a set of boards from OSHpark. We'll see.
