I want to make a dining room table that is reminiscent of a wire frame model (think a computer graphics mesh). I decided to start small and make this side table. From this small version I learned that I should use copper clad welding rod instead of stainless (because even though they make stainless solder and flux, it is not as strong or easy to use as normal solder). Also the table used way more welding rod than I thought. So for a full size dining room table I will probably need 20-40 lbs of welding rod. I also plan to put a frosted glass top on it.

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.

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.

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.

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.
