Color of Umphrey's Poster

Back in May 2015 I wrote a little program to sequence an Umphrey's light show into a cool looking image. I finally got around to picking up that old code. I sequenced the whole concert and put it together in a nifty poster.

You can get prints at and I'll add more shows there eventually. All proceeds go to the Jacqueline Rush Foundation.

With arcs (I like this one better)

Doomguy hardware monitor

This isn't my invention, I just replicated something another guy made and posted to Reddit. I had to change a bunch of code to make it work with my display. Doomguy turns bloody when temps exceed 60 degrees. Really cool addition to my gaming rig. Yes my desk is a disaster.

"Computron" AM Radio to Bluetooth Speaker

I bought this little AM radio a few years ago intending to turn it into a Bluetooth speaker. I think they are from the 1970's or 80's.

I used a super simple circuit, just a DW-CT14+ Bluetooth amp and a now discontinued SparkFun Power Cell. The batter can also be driven using this Icstation TP4056. I also 3D printed a little mount in there to keep the USB port steady.

3D Printed iPad Mini Suction Mount

I made this because my other airplane has a 1" ball built in to the dash, so I could share parts of my RAM suction mount between airplanes. This brings the iPad quite close to you in portrait orientation so it's good for IFR.

Holding Pattern Entry Quiz

I'm studying for my instrument rating. I made this tool to help me study which entries to use into holding patterns.

Battery-powered Wii sensor bar for projector screen

Just a couple of infrared LEDs, a red LED to show it's on, a battery pack and a 3d printed mount. Used a 10 ohm resistor on the infrared LEDs, so it should hold a charge for about 15 hours.
