To use the CMU machine shop full time, I had to take a small course on machining. The class was straight forward, and I knew about 75% of what was taught. I did learn a lot though and picked up some new tricks. We learned the main concepts through two small projects, a pencil holder and a plumb-bob, performing the cutting operations ourselves. Once the skill was demonstrated, we moved on, so most people didn’t finish the projects. However, I spent a little time after class putting the finishing touches on the parts. I’ve machined a million parts for previous jobs but never had the opportunity to display them. While these two parts are pretty basic and not a good indicator of my skill level, I thought it would be fun to “do it right”.
A quick post to document my failures and final success.
I’ve been using PDANet on my Windows 7 machine to USB-tether my Nexus S 4g (on Sprint) running Android 2 (then 4) for a year now and its been great. I was 100% pleased with the setup. Unfortunately I just got sick of Windows 7 and decided to switch to Ubuntu 12.04. I’d heard good things and was back on the linux bandwagon.

Design and build a machine that fires Nerf foam balls and hits static and moving targets with great accuracy and speed.
Four engineers joined forces to accept the challenge.

I have a lot of USB devices which I’m continually plugging/unplugging from my Windows 7 machine. I wanted some custom icons to appear on the desktop when specific devices are plugged in. I hacked together a solution from several other people’s solutions around the web to put together a (hopefully) complete how-to:
The year lasted longer than I expected. I was planning on not riding from September til now. Well gladly, that didn’t happen. Here’s a quick blast of what happened since August.
At the track, I finished very well at the third Pro Series Race. I technically finished the ominum in 6th place. However, the results don’t show how the rain screwed me out of 5th place. I had won entrance into the sprint final, where last place was still guaranteed one point. That would have bumped me into 5th place. Well five minutes before the race started, the rain came in and soaked my chances. Anyways, I stuck it to Marty later in the year!
Work obligations kept me from coming down most of the rest of the season. The one opportunity I had to make it down, I continued my Chariot race winning streak. I ended the year in 15th place overall out of 80+ racers. The highlight of the year was winning Team of the Year with Faster Mustache.
