"I was poking around in the JeeLabs RF12 library recently and noticed that it now supports the ATtiny microcontrollers – it’s what the new JeeNode Micro uses, which got me thinking about even smaller, simpler wireless temperature sensor modules again."

"This paper presents the design, implementation, and evaluation of the RFID Guardian, the first-ever unified platform for RFID security and privacy administration. The RFID Guardian resembles an ‘RFID firewall,’ that monitors and controls access to RFID tags by combining a standard-issue RFID reader with unique RFID tag emulation capabilities."

"I thought up the idea that it would be really cool to control a remote control car controlled by the parallel port. I did some research and Mike Beauchamp did just that and to top it off it’s controllable over the internet."

"The challenge here was to integrate different technologies in a working project. In particular I wanted to use the iPhone to send/receive data to/from an Arduino, build a remotely controlled robot using a WiFi network and hook up a data logger station capturing the different sensor data."

"Here’s a cheap way to build your own fully customisable infrared PC remote control. If you already have a suitable infrared remote control going spare you can build one of these for under £4, it will allow you to use most infrared remote controls to issue keyboard commands on your PC."

"All of the hardware and software is open (in the GPL sense), including parts lists, circuit board and chassis designs, and software. With a stated goal to produce sub-€100 robots, I’d really like to see this take off. Combined with a wireless power surface, a micro-robot in perpetual motion would make a great desk ornament!"

"For our final project, we re-engineered a remote control car to autonomously navigate through a track by detecting lanes and centering itself between them as well as detect objects in front of it and avoid collision. The RC car detects lanes through image input from a low-resolution camera mounted at its front. Using an IR distance sensor, the car determines when to stop accelerating once a certain distance between a forward object has been breached."

"FPV is one of my ultimate goals flying a quadcopter. The quadcopter FPV videos are just so amazing! You need at least a video receiver, transmitter and a camera for the FPV system, and it could get quite expensive."

"To the RC car I removed all the electronics except the motors and i installed 6 new AA 1,2V rechargeable NiMh 1900mAh batteries. I designed new electronics based on Arduino with a HC-05 Bluetooth module and two h-bridge ic’s. The SN754410 for steering motor and the L298N for forward/backward motor. For both ic’s i connected parallel the channels, 1 with 4 and 2 with 3."

"The ultrasonic haptic vision system enables a person to navigate hallways and around large objects without sight, through the use of an ultrasonic rangefinder that haptically interfaces with the user via tiny vibrating motors mounted on the user’s head."
