“The Double Down card dealer is a fully programmable automated card dealer. It has the ability to deal a card in two directions (left or right, dealer or player, etc) while at the same time moving linearly perpendicular to those directions (card stack 1, 2, 3, etc).”

“The FabISP is an in-system programmer for AVR microcontrollers, designed for production within a FabLab. That is, it allows you to program the microcontrollers on other boards you make, using nothing but a USB cable and 6-pin IDC to 6-pin IDC cable. It’s based on the USBtiny and V-USB firmwares, which allow the ATtiny44 to perform USB communication in software.”

“A while back, I did a wireless temperature sensor project using XBee radios….So I decided to try the same project using inexpensive RF devices. I used a 434MHz transmitter ($4) and receiver ($5) from Sparkfun, and had great success with these cheap devices. I also used a simple LM34 Fahrenheit temperature sensor, two Arduinos, and a two-digit LED display to show the temperature at the receiver end.”

“This ain’t yet another ultimate, ultrafast and all-too-miniaturized USB-gadget. It is the ‘official’ USB-version of the XR232-TRNG, taking advantage from the benefits of USB, but retaining fundamental XR232-philosophy of independency, security, transparency and compatibility.”

“This project will describe how to make a simple digital voltmeter (DVM) using a PIC16F688 microcontroller. The range of this DVM is 0-20V, but you can easily increase or decrease the range of input voltage as your requirements after you understand the voltage scaling method described in this project.”

“I bought a Lego Mindstorms kit last month to mess with, I’ve got some ideas for robot localisation that I want to try out. Anyway, the kit comes with a sonar range finder but I wanted a little more accuracy and smaller detection area….A couple of companies sell after market sensors for the NXT, Mindsensors and HiTechnic but it’s much more fun to design and build your own.”

“I’ve got a pre-paid electricity meter installed at my new place in Cape Town. It outputs a 1/1kWh pulse via a LED on the front panel. I thought it would be pretty cool to read and log the power consumption of my house. It’s also an excuse to play with WiFi and other fun stuff.”
