did not go to Caltech intending to be an electrical engineer. But when I discovered that the proper arrangement of wires and components would make lights and sounds when I pressed buttons, I was hooked. These are some of the projects that I have made since then, roughly in chronological order.

f you are looking for complex, well-documented embedded systems, check out Dax and the Coke Machine. If you are looking for "Gee whiz, that's a cool gadget", check out, well, pretty much everything else, especially near the end.

Digital Audio Recorder: My first exposure to digital electronics. Okay, so everyone else in the class did the same project, but did theirs have an oscilloscope, four-function calculator, and a hangman game?

PowerPuncher: All the doors in the Caltech dorms have the same sort of combo locks on them. So why not build something to crack the locks?

Spiffy Dual Locator: No one ever cared where I or my roommate was. But if they did, they could look at this cool gadget that was mounted on our door.

Turbo-2D GrafixxZapper 9000: My first large-scale VLSI design was this graphics processor designed to drive an LED matrix.

LED Matrix: And then I built an LED matrix. Imagine that.

Wireless Headphones: My first real analog design. An infrared audio transmitter/receiver set.

PICboard: A generic controller board for robotic work. Also my first PCB design.

Air Guitar: A wireless musical instrument. Move your arms around and bend your fingers, and kick out some tunes. One of my coolest projects.

Ditch Day stack: Ditch Day is Tomorrow most of the time, but when it was Today, our room had somehow turned into an alien spacecraft. And alien spacecrafts need alien control consoles.

Coke Machine: The Lloyd House Coke machine was already legendary. But I wanted to make it legendarier. One of my best projects, and certainly the best documented.

DAX: The Dual-AXis rotation sensor. Spin it around, and it'll tell you exactly how many degrees it was spun. Like a record, baby. Right round, round round. Technical report and source code available.

Air Conditioner Project: Have you ever wished you could turn on your air conditioner remotely with a phone call? When you are with an EE, be careful what you wish for. Another very cool project, and not just in the literal sense.

Mailbox Project: Also known as the "Jaideep Project" for esoteric reasons, this is a good example of using the power of electronics to promote laziness.
