Zach built his own version of the game Catch Phrase : [via]
When I started playing around with embedded systems, I wanted to do something more interesting than just flashing an LED, and I spent a lot of time trying to come up with project ideas that would be useful (or at least fun) when they were done. One of the first ideas I had was to make my own version of catchphrase. Most of my extended family enjoys the game, but one problem with it is that some of the younger nephews can’t understand most of the words. I thought it would be fun to create a version that they could play, and then the project grew from there.

This is my board layout for USBasp programmer. On that programmer homepage is a lot of designs, different MCU types and package sizes of processors. But nothing that I would like. I wanted really small size but with the same features. I used the original schematics from Fischl and created new layout with some SMD parts.

This simple DC/DC step-down converter is perfect for breadboard design or replacement of 78xx stabilizers. It’s not so powerful but it can give about 350mA and even if you apply higher input voltage, it doesn’t get much hot like the 78xx ones.

Martin Hubacek took a TI Stellaris EVALBOT and interfaced it to a Nintendo Nunchuck. This lets the robot drive around using the accelerometer or the joystick. Check details and code on the link below. [via]

I have long admired the Bus Pirate, and wanted to build my own. Since I already have an FTDI USB-to-TTY cable, I thought I might replace the FTDI FT232RL subsystem on the Bus Pirate (v3b) with a header for my cable, to save on component cost and board space.
