Simple Raspberry Pi Mount
Here's a simple mount I made with just a base, some standoffs, and some rubber pads to hold Raspberry Pi's while I develop projects on them. It provides a stable and easy way to access the SD card as well as the power plug.
I've added a Sparkfun RS232 Shifter converter so I can use the available serial port on the Raspberry. The mount for that is actually a cut card slot from an old PC. I have also populated the reset switch which I frequently use.
