"This page outlines my project to home-brew a dedicated box for ‘tuning in’ these online stations…I wanted to make something to match the other stereo hardware I have. I also like that I can personalize every aspect of the design, and put to use some of the hardware I’ve collected over the years."

"Over a year ago I started to work on a small balancing robot. Between learning more about communication protocols and feedback loops I also had periods of schoolwork that kept me from this hobby. In the end my little robot was balancing on his own and I could send steering and throttle commands wirelessly."

"Printed circuit boards (PCBs) now encompass much more than pure digital or mixed-signal technologies, and the PCB layout designer faces many more challenges when designing sub-assemblies with high frequency RF and microwave. The RF frequency range is typically from 500 MHz to 2 GHz, and designs above 100 MHz are considered RF. The microwave frequency range is anything above 2 GHz."

"The purpose of Project 3 was to actually get the quadcopter into the air, and possibly make it autonomously hover in place. Since the copter mechanical design was mostly finished during Project 2, Project 3 consisted mostly of the quadcopter software development and some minor troubleshooting tasks with electronics. In order to control the copter, the team decided to modify AeroQuad software to meet the demands of our configuration."

"A reflow toaster oven and a simple laser cutter. Why a laser cutter? Using a reflow oven makes things easier, but we still have the problem of putting the correct amount of solder paste on the board. This can be done using a PCB stencil."

"We’ve had a couple of rain barrels for several years. At our old house they were mainly used as a source of water for our garden. At the new house, we have much more of a problem with puddles around the house, so the rain barrels are an important buffer for managing the water from large storms. So rather than keeping the rain barrels full all the time, we now want to make sure the barrels are empty before a big rain. This obviously calls for some type of automation system! "

"I really believed there would be a conflict using the PS2 controller with the RFM12 modules, since they both use SPI. But the great thing is that Bill Porter wrote the PS2X library so that the pins are changeable, aka software SPI. So the RFM12B can use hardware SPI, and the PS2 can use its software SPI bit banging."

"This project uses an RF receiver module to trigger a pulsing LED Heart when the transmitter comes within range. I made this for my fiance for Valentine’s Day this year."

"We designed and built a wireless computer pointing device with accelerometer based movement control. Our implementation allows the user to wear a set of hardware (a glove and connected armband) and control a cursor through different hand orientations and finger presses. Users can operate their computers with their hands in midair without the hassle of desks surfaces or wires."
