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.

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.

Exposure Unit

Just need to put in the glass 

Here is the exposure unit that I made in 2007 with my friend May Yang.  (thanks for the Pics May!) Can you say pretty blue light? It has 10 actinic (420 nm) fluorescent bulbs totaling 400W! Made for exposing silkscreens, but other uses too.

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.

Bike LED tail light



This is an LED bike tail light that I made in 2004.

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.

Plate Chair 1.0

Plate Chair rendering



I designed this chair to use one of the simplest forms of a raw material; a plate.  By making a careful series of cuts in the plate and then doing a series of bending operations you get a chair! Best of all no scrap material is generated.

RGB Box Lamp 1.0

Monday, January 5th, 2009




I made this lamp in 2004.  The balsa and tissue construction worked very well.  The simple linear potentiometer RGB brightness control left something to be desired.

ModuLamp 1.0

ModuLamp 1.0



 This is a lamp I put together one day in early 2004.  It uses a CCFL lamp and some vellum to make a functional and cool looking light source.  It is a visual representation of sound waves.
