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!
3D printing to the rescue!
This is exactly what makes home 3D printers so wonderful. Why spend $40 for an adapter, when you can make one for just a few dollars. Make sure to read the full article, as he has lots of great information and pictures.
