"Lately, I’ve been working with different sensors as part of my day job at TI. TI happens to have recently released a booster pack for the Stellaris and Tiva launchpads that contains (among other things) an accelerometer, a gyroscope, and a magnetometer. I figured I’d use my recent experience to do something fun with sensors in my free time :)."

"The Magic 8-Ball Pumpkin was my 2012 entry in the Rosenwinkel pumpkin carving competition….My entry this year was a working Magic 8-Ball, powered by an Arduino Mega and a set of sensors to detect motion. A gyroscope and an accelerometer are used to detect when the 8-Ball has been picked up and/or shaken, while an IR receiver is used to power on or off in response to a remote control. "

"There are two CPU in our project, ATmega328 and ATmega1284. We set up the wireless communication by two Xbee chips. One of them connects with ATmega328 working as the transmitter to transmit the signal, another one is connected with ATmega1284 to be the receiver. We pick up ATmega328 to be our transmitter part because there is a microphone on it which could receive and store the voice signal from people."

"The goal of this project is to collect heartbeat information on a computer with minimal cost and minimal complexity. I accomplished this with fewer than a dozen components. It serves both as a light-based heartbeat monitor, and an electrocardiogram (ECG) to visualize electrical activity generated by heart while it contracts."

"LED Reflectometer is a device which used to measure this property. Mainly it transmits pulses of LED light into the environment, and monitors the strength of the LED light reflected back from objects nearby. This instrument can transmit different pulses and can detect the reflected signal and can show the difference between those two signals."

"In the mining rig described here an FPGA does all the hard work (SHA-256 hashing) and communicates over a serial link with a Raspberry Pi. The latter requesting new work from, and submitting proof of work done to, a Bitcoin mining pool."

"The purpose of the prototype was to demonstrate the feasibility of a small, highly maneuverable search and rescue robot. As such, the completed prototype was successful. Capabilities include a ground speed of 10 inches per second, battery life of 50 minutes, wireless range of between 50 and 150 feet, weight of 14.5 pounds and the ability to climb stairs."

"In just a few hours of hacking and experimenting, we turned this radio-controlled car into a WebSocket-controlled car. Don’t worry, no actual cars (or bunnies) were harmed in the making of this demo, as you’ll see as we walk through the hardware and software we used."
