Simple high speed motor

Saturday, June 4th, 2011

This is a quick motor I made using a single phase brushless motor controller IC (AH5798-yg) a coil of wire (100 turns of 38 awg)  and a magnetic sphere (Neodymium Iron Boron, N42). Based on the sound (via my FFT app on my iphone)  it is spinning at either 74400 or 37200 rpm.

Solid state retrofit

Saturday, June 4th, 2011

For my senior design II project I designed a LED light fixture to replace the standard fluorescent ones in the campus apartments.  This is my final report.

LEDs! and some other projects

I would recommend checking out my flickr page for more of my projects (I’m a little busy right now). But I have been making some custom PCBs, playing with some interactive video, and dabbling in ultracapacitors.

Bubbles Display

Saturday, October 9th, 2010

This bubble display uses glycerine and air to produce pattens and text.  This version is 8 pixels wide.  The concept can be scaled up in a modular fashion to enable large installations (ie an entire wall in a restaurant or bar, or a free standing divider in a lobby or office).  Control is implemented using an arduino micro controller board. Future additions will include a streaming interface (to upload text and commands on the fly), and a more refined modular design.  This prototype is on display at Momentum Tulsa 2010.

This is a Peggy 2le Kit that I assembled from It is a 25×25 LED matrix that is based around an Atmel ATMEGA328  and programable through the arduino environment.  I have written some software for it as an exercise to get back into programing.  Check out the videos of the Peggy lighting up its 625 LEDs!

Everything together

Well, here are some pictures of my sr. design project. I will post documentation later.

Hondata S300 install

Parts for Hondata S300 installThis is the Hondata S300 I installed in my ECU so I could tune my car (more on that later).  The S300 is an awesome tool that enables USB tuning and adds many features to the Honda ECU.

POV 1.0

Tuesday, January 6th, 2009



This is a POV display I made in 2004.  I designed and manually encoded all of the font information as hex values for the code.  Little did I know that 4 years latter I would be doing the same thing except with Chinese characters and for OCR software.  It was some how less exciting the second time around but at least I was getting paid for it.
