Last year I bought a Canon PowerShot SX200 on ebay. I wanted to play a bit with CHDK, the Canon Hack Development Kit to make some timelapse things. Problem was, the battery would hold only up for 2 hours or so. Even worse, the camera has no power jack to attach a power supply. The solution is to buy a battery dummy that has a jack on its back. That costs like 30 euros!

nneth Finnegan has been working on thermocouple adapter called SerialCouple – [via]
The SerialCouple line of boards are simple, easy to use single-channel thermocouple adapters, meant to be an interface between a thermocouple and a computer or other embedded system. Shown in the pictures are the model one boards, which are meant to be plugged into FTDI-like USB-to-Serial adapters, but a second model based on RS-232 is in the works.

MickM built flat cable to header converter adapters : [via]
I was using some character LCD displays and realised that the cables were impossible to plug into the displays that I actually had. My PCB was single row of 16, the LCD was 2×7, no backlight. So I made an adapter for it.

Just a little circuitboard to interface I²C-chips to the parallel-port.

Gameduino connects your Arduino to a VGA monitor and speakers, so anyone who can write an Arduino sketch can create video games. It’s packed full of 8-bit game goodness: hundreds of sprites, smooth scrolling, multi-channel stereo sound.

XBee modems are one of the easiest ways to create a wireless point-to-point or mesh network. They have error correction, are configured with AT commands, come in multiple flavors and can create a wireless serial link out of the box! I wanted to make a wireless Arduino project but all the adapter boards on the market made me unhappy. So I designed what I think is an excellent low-cost adapter board.
