"The main idea behind this project was to construct a system on the Altera DE2 board that is capable of detecting the location of a sound source. We envisioned many purposes for such an instrument in gaming and other types of systems; however, to demonstrate our sound localizing capability in this project, we decided to use it for robot control."

"The Senior Year Design Project was named Vanguard by the team. He is a remote controlled surveillance robot. To avoid data communication problems we decided to use different protocols for controlling the wireless camera and the robot. The robot can be controlled through desktop or laptop computers while the video can be controlled through internet, adhoc, WAN and LAN. It is powered by two batteries. One for the circuit and one for its motors."

"Last weekend brought an interesting challenge: to create a remote-controlled, small-sized dry ice ‘fog’ dispenser for a company event. In the end it wasn’t used, but I had a lot of fun building it anyway. Here is how it was done…"

"The goal of the GRITSBot project is to make multi-agent experiments more accessible to the research community at large as well as to students of all age groups. In a further step, we intend to open up a show testbed to the general public."

"In this short article, I present a nifty technique for promiscuously sniffing such radios by (1) limiting the MAC address to 2 bytes, (2) disabling checksums, (3) setting the MAC to be the same as the preamble, and (4) sorting received noise for valid MAC addresses which may later be sniffed explicitly."

"I am very pleased to announce that I have now added support for the PS4 controller via Bluetooth. This will allow you to read all the buttons and joysticks with the same API as all the other libraries I have written for the USB Host library."

"Currently on display at Gallery iam8bit in Los Angeles, California, I present to you the ‘Backlit Apocalyptic Mega Man NES’! This is a very unique collaborative art piece. I teamed up with artists Noel McEwen and Gary Bedell to bring this one to life."

"I recently built another Bitfrore prototype so I thought I’d take the opportunity to capture the whole process from start to finish. The prototypes are completely hand built so its a process that anyone could use to develop their own electronics at home. I use the toner transfer method for etching my homemade PCBs. This process allows a very fast turn around between design and testing."

"…Here is a very simple project of controlling a small DC-motor (taken from an old personal cassette player) with ATmega8. The ATmega8 has three PWM channels, out of which two are used here. PWM waveforms are fed to MOSFET (RFD3055) H-bridge."

"There are 4 distinct modules, all connected by a 4-wire bus that provides power, ground, and two com lines. I separated the tasks into input-output pairs: audio i/o, user i/o (button and light), and radio i/o. The center module coordinates communication between the others and memory."
