"Steno technology has existed for about a century, and has been compatible with computers for over 30 years, but until now the hardware and software necessary to write at 240 WPM has been restricted to professional stenographers. The Open Steno Project seeks to bring free software, low-cost hardware, and interactive learning tools to everyone who wants to use steno for their personal or professional pursuits."

"For the last several weeks I’ve been hacking together a small prototype of a microcontroller (ATTiny2313)-powered prime number generator. I can finally say that it is complete, functional, and elegant. The name says what it does, so I won’t waste time describing it."

"We stripped out the insides of the device and mounted in our stackable led controller boards. These two boards are designed to convert random amount of LEDs to Arduino controlled matrix. There is high side controller – 8 P-channel mosfets per board. And low side controller uses TI TLC5940 16 channel led controller."

"So I decided to give Thanksgiving the attention it deserves. As a kid, I loved making decorations for the Thanksgiving table. I thought whoever came up with the idea that your hand could be traced and transformed into a turkey was a genius…Which is how the idea struck me, and I embarked on my second e-textile project: a LED hand turkey sweater."

"Computer controlled Etch-a-Sketches are not rare things. In fact, there is at least one other such device made with the Raspberry Pi. However, I think my Etch-a-Pi design is pretty reasonable, so I’m describing how to build it here."

"F18A stands for ‘FPGA TMS9918A’ (hence the project’s title) and will be 100% hardware and pin compatible replacement for a TMS9918A VDP (video display processor)."

"This was my first attempt at making a rc bike chassis using carbon fibre was for a Thunder Tiger Electric RC motorbike. The original frame panels were scanned and then traced in Adobe Illustrator. I then modified the layout of the panels to reduce weight and then exported them for cutting on our milling machine."

"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."
