"This project is an attempt to recreate the classic game in a digital format. To spice things up a bit, instead of using the regular 2 player setup it uses an inbuilt AI mechanism to compete against the player."

"Every haunted well needs a trained demon-summoning witch. Our haunted well has just the thing. A witch standing nearby, outfitted with the latest electronics. She’s sporting a uMP3 MP3 playing card, plus a Scary-Terry audio servo driver tied to her skull-head. And of course she’s also customized with a pair of (diffused) green LED eyes that will also flash as she speaks."

"The Robotic Pet is an automated robot that can mimic common pets behaviours, like entertaining with a ball autonomously and interacting with human gesture freely. As the final project of EE 125 Introduction to Robotics class, the robotic pet is built on the UC Berkeley TETRIX robot platform."

"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."

"The modular robot or toy platform is essentially built off of a chassis that enables the user to add any number of 3D printed toy housings to it ranging from the aforementioned bulldozer, tank, digger toy or anything else that a user wants to program it as using the code that was generously provided by hobbyman."

" It would be great if I could print out the time and ranking directly, so if there is no PC, the system can be small and tiny. So here is my next project and tutorial: Printing with the Freedom board!"

"In this tutorial I will be detailing how to generate analogue voltages using a Raspberry Pi and an external Digital to Analogue Converter (DAC) to control the brightness of an LED. Although the Raspberry Pi can interface with various low-level hardware using it’s GPIO lines, SPI, I2C and serial UART interface, it does not have an DAC interface for generating analogue voltage levels. Instead the user must use an external DAC device controlled by one of the available low-level hardware interfaces, such as SPI and I2C."

"At the highest level, the design of our project centers around an acquisition circuit, data processing in two MCUs, and the output on a TV screen. The first part of the stethoscope is the acquisition unit, which consists of an actual stethoscope mated with a microphone, and an amplifier circuit. The microphone captures the audible signal from the body that is acoustically amplified by the stethoscope."

"I will not go into details on how to control humidity. Instead I’ll describe what motivated me to design and create my own temperature and humidity sensor which reports its readings every minute to a central Linux server."

"I built this Arduino radar project, where I control the brightness of an LED with my breath. In this tutorial, I will show you exactly how to do it. It was an experiment to get the XeThru radar to work with Arduino. I plan to expand on this later, and build more useful applications. And I will share with you how to connect the hardware, and how to create the Arduino code."
