I can't even remember all the projects I've worked on over the years but here is a sample:
- Multi-channel Light Dimmer board for the Marion High School stage (with Tony Weber)
- String Synthesizer using analog bucket-brigade devices (based on a Popular Electronic design)
- TVT3 Television Typewriter (early terminal)
- A couple of analog and several Arduino digital Spectrum Analyzers
- Six or seven sets of speakers of various sizes and shapes
- Munny Steampunk Ipod Shuffle player with custom LED VU meters (above)
- Munny Steampunk Satellite Speakers (above) with a Large Munny Sreampunk Subwoofer
- Munny Electronic Speakers
- Several sound-responsive LED headbands, a very ugly Christmas sweater with Arduino driven LEDs and a bright LED Christmas hat
- IotHackday 2015 - Jukebox Backpack
ESD Testing MethodI'm not sure how unique this is, but I discovered a technique of non-destructively determining the most immunity sensitive areas of a PCB assembly. By using an ESD gun to 'zap' a small copper patch held close to the board, it's possible to map ESD sensitivity to the RF emissions from the patch and correlate those to specific signals on the layout.

IoT Hackday 2015Our team built a portable Jukebox that attaches to your computer bag.
The speaker enclosures were built from 2" PVC pipe in two mirrored sections to fit the backpack. 320+ Neopixel LEDs were attached with clear tape or hot glue and wired into one long string. A Particle Photon used programed to get tweets sent to @jukeboxbackpack and transmits the specific tweeted number to an Arduino Nano. The Nano would then drive an MP3 player shield to play the song corresponding to that number (held on an SD card). A separate Arduino Micro Pro ran the LED show, with a microphone attached to a small hole in the side of the speaker enclosure. A 11.7V 2600mAh Lithium ion battery was connected to two DC-DC 5V converters, one for each side of the LED light strips and the 12V audio Amp was connected directly to the battery. A separate 7.2V Lion battery was used for the Photon and Nano. The music from the MP3 player output jack was connected to the amp via a normal audio cable. |

Cube-It - Impaired Attention Measuring Device
Check out the Devpost link here. The goal is to create a device that can help measure how long someone takes to perform simple requests, along with how much 'fidgeting' they perform while doing it. The prototype contains an Adafruit Bluetooth Feather, 9-DOF sensor, battery and a matrix of switches and LEDs on each face of the cube. The mechanical design is on OnShape - just search for Cube-it. |
