Machining Brass & More Electronics - 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 that later...)  One of the things that I have been working on for another class is machining a power cylinder for a Sterling engine.  I changed the design to include machined letters.

I have also been playing around with a number of electronics things.  I bought an Open Bench Logic Sniffer which is very cool but comes without a case.   I found a design for one on Thingiverse but wanted to have cutouts for the optional headers so I modified it (here).

 

I also bought a Freeduino which is a very nice little thru-hole Arduino clone kit.  It was very easy to assemble.

I wanted a case for it as well so I designed and printed one.

This case will also be one of my examples at the OpenSCAD workshop I am teaching at Metrix Create: Space on Sunday, March 27 from 2-4pm.

RepRap Mendel, Metrix Create: Space, & Engineering Discovery Days

It has been a little while since I last posted.  I have been busily working on getting the Solheim Rapid Prototyping Laboratory RepRap Mendel completed for the UW Engineering Discovery Days.  We got it working after several problems with our electronics and a lot of help from the people over at Metrix Create: Space.  Be sure to check out the pictures (here) of us working on it down there.

Here are some additional pictures of the Mendel and the first prints that we were able to get from it.

Now we are going to work on improving the print quality, repairing the electronics better and starting construction of a few more bots...
