Projects

An 8 bit Flash Analog-to-Digital converter I designed (And designed the masks!) for school (MSEE @ RIT). The documentation can be read by clicking here.

Paper I wrote for a class at RIT, basically a survey in low-voltage CMOS design. A good introductory read - click here.

I wanted to be able to fall asleep listening to my stereo playing the radio, but I did not have a sleep timer fuction on my receiver, so I built this device to add sleep timer functionality to the stereo. The timer can be configured to run in two ranges: 99..1 seconds or 99..1 minutes.

This digital thermometer remembers the 12-hours high and low temperatures. This design uses a PIC microcontroller with a built in A/D converter. All the parts are tolerant to temperatures from -40 to 100 degrees Fahrenheit, so you can keep the device outside.

I built a cheap laser pattern generator from stuff I found lying around my house and a few store bought items, I think I spent <$10. Here I am including the plans for the circuit and pictures of the finished project. Once upon a time I also took pictures of the patterns using a digital camera, but the shutter speed was too fast, so only part of the pattern was viewable.
