"While the initial goal of this project was to learn about the basic workings of a SSTC before embarking on a DRSSTC, SSTC 1 performed spectacularly and can be modulated via fiber-optic in a variety of ways, from producing sword-like spiral sparks to playing music via an analog stereo input! "

"The LEDs are controlled by one ATmega328 with 15 8bit shift registors (74HC595) sitting on two PCBs in the center of the globe. The power is supplied via slip rings. The two PCBs and the mechanical part are again self-made."

"Behold, the $75 DIY sous vide heating immersion circulator! By scrapping together parts that are readily available on eBay and Amazon, I was able to build a self-contained device that heats and circulates water while maintaining a temperature accurate to 0.1 degree Celsius."

"To build this tool I’ve used two old CD-ROM writer that lays around in my garage.
The X/Y positioning system it is build using the CD-ROM motor assembly. For the engraving laser I use the CD-ROM writer laser. With this hardware the engraving area are will be almost 38mm x 38mm."

"Essentially, I wanted to be able to control a little robotic arm / turret using a PC with a serial port. I thought this was a worthwhile project because I could later adapt it to aim a webcam, Nerf toy gun, or maybe even a felt pen so it could draw pictures."

"As I started to get into multi-rotor aircraft, I came across the KKMulticopter platform as a good way to build inexpensive practice aircraft. As I looked at the design, I realized that it would be pretty easy to adapt it to a two-prop tilt-rotor design, but before I could begin coding the software for it, they released a firmware for just that! When I saw this video, I knew I was going to have to build one… and that I would use it for evil."

"Our project was to create a new type of controller for a remote controlled helicopter. This new controller is in the shape of a hand paddle that a user can move around to control the movements of the helicopter."

"A stepper motor turns the ultrasonic range finder 360 degrees and back. After each step the range finder is activated and the distance is measured. When two measurements have been made the PIC sends the data to the PC using an asynchronous interrupt transfer"

"Why? Because I can. To learn how electronics behave at cryogenic temperatures. And just curious how much juice you can squeeze out of AVR if you push hard enough This also produced some results relevant to desktop processors overclocking with liquid nitrogen cooling."
