Been a little while since I've posted.

Fixed up the previous post, as the wiring diagram I had posted was incorrect.  Replace it with better versions (still untested) but I believe they are now correct.

All of my 3D printed parts are now done.  I've re-printed the tower, as I wasn't happy with the red one that I done.  The final camera tower I'll be building off will be a white one, printed using Village Plastics HIPS.

The parts have continued to trickle in from around the world.  Still waiting for a few more parts before I can get started, but am getting pretty close.

I'm erring on the side of caution, and have been ordering multiple parts from various locations.  Currently have a couple sets of lasers.  One set from 3.3-5v versions from Adafruit, and another set of 3.3v lasers off ebay (same ones Bill Owens bought).  I have received the motor controller board(s).  Ordered four off e-bay and one from Aleph Objects, Inc.  I have an assortment of NEMA17 stepper motors to work with as well.

I have all the capacitors, Raspberry Pi2, variable resistors, and breadboard.

Still waiting for the power supply from Adafruit, the ULN2003A, and the LD1117.

Managed to also get my hands on a PCB layout for this circuit (even got the actual EAGLE files), so I could have the board printed.  Here's a picture of the circuit.  I'm tempted to place an order for these boards to be made, but have to order in quantities of 10.  Given that I only need one, if I can get some people interested in sharing the cost, then I'll go ahead and order a set.  Right now, I'm planning on going with an Adafruit Protoboard, but may in the end order this as it's much nicer looking.


Going to need to find some time and start assembling what I have so far.  Time is a precious commodity lately, and I haven't had much free time... doesn't keep me from thinking about the project however.  Hopefully I'll get something happening as soon as the parts arrive.  Can't wait!

  1. A smaller run alternative for PCBs. They are good quality as well, 3 for $51 USD. http://www.expresspcb.com/
    I am very interested to see this project move forward :)

  3. would you share the pcb file ? I can order a printed board from china and give one to you FOC :p
