Electronics setbacks, an 11th Prusa, & an OpenSCAD Workshop

It has been a while since my last post.  I have been rather busy this quarter with my senior capstone project (Stay tuned for more on that later...)

I recently had a minor setback with my printer when something happened to my motherboard.  I am not sure exactly what occurred but it became unresponsive and I could not re-flash it.  I was not sure what to do except either replace the board or at least the Atmega644p.  I was saved by Mark Ganter at Open3DP who had some spare Gen3 boards that needed TLC.  I was able to find one that was in better shape than mine and get printing again.  I still bought a new Atmega644p chip and plan to try repairing my original board.  As much for the learning experience as anything else (I also hate to throw away something that could be fixed.)
The picture is not too exciting as it is just a working motherboard..
I have now printed another complete Prusa (available on eMAKERshop) using the replacement board (the first picture is of this set).

I am teaching an OpenSCAD workshop at Metrix Create: Space on Sunday, March 27 from 2-4pm.
