Full power tests of motorcycle PDU

I pushed 185 watts through my custom DC relays last night. They ate up that power like a champ. Likewise, I've also been testing it in the off condition to measure its steady off power consumption. The cards burn 150 nano amps or 1.8uW when off. That's means it's about 80 mega ohms which is OUTSTANDING. This project is really moving along nicely. I have some serious burn in testing to do and then it's time to get the main board encapsulated and do some real life testing. That's going to be fun!

A Capacitive-Touch Janko Keyboard: What I Did at the 2017 Georgia Tech Moog Hackathon

Last weekend (February 10-12, 2017) I made a Janko-layout capacitive-touch keyboard for the Moog Werkstatt at the Georgia Tech Moog Hackathon. The day after (Monday the 13th), I made this short video of the keyboard being played: "Capacitive Touch Janko Keyboard for Moog Werkstatt" (Text from the video doobly doo) This is a Janko-layout touch keyboard I made at the 2017 Moog Hackathon at Georgia Tech, February 10-12. I'm playing a few classic bass and melody lines from popular and classic tunes. I only have one octave (13 notes) connected so far. The capacitive touch sensors use MPR121 capacitive-touch chips, on breakout boards from Adafruit (Moog Hackathon sponsor Sparkfun makes a similar board for the same chip). The example code from Adafruit was modified to read four boards (using the Adafruit library and making four sensor objects and initializing each to one of the four I2C addresses is remarkably easy for anyone with moderate familiarity with C++), and ...

Infinity Mirror Prototype build

For our art project for Alchemy this year, we plan to build a huge archway in the forest with a portal to hyperspace. This is no easy task, so we decided to do some small-scale prototyping so that we can look into some of the challenges of this build and play with different effects to see what looks the coolest. Our design is based around an infinity mirror, which is a cool device that is build from one regular mirror and one two-way mirror. Lights placed in the center echo between the two mirrors until they fade too low to be seen. The viewer looks through the transparent side of the two-way mirror and can see the effect move with their perspective. Kevin and Edward working with the assembled frame. That's the two-way mirror in the foreground. I had some help with the build from Kevin and Edward, who came in for the Tuesday night open house and got recruited to the project. Nathan (not pictured) also joined in to help, so we had 4 people working on it. We also ma...
