Raspi/Arduino Drive sled

thingiverse

Still a work in progress. I still need to print one of these and double-check all the dimensions and locations of the four screw holes. Wanted a way to utilize an empty drive bay to hold an Arduino or RasPi (or both) computer. Had the idea to use smaller computers to interface with the real world, automate downloads from the internet, or execute mass actions while saving power by not running the desktop computer all the time. But wanted to use the keyboard and display of the bigger computer along with some software to easily configure the smaller computers. A small LCD display, a few LEDs, and a switch or rotary switch or two will serve as the interface for the small computer. I also want the small computer to be able to turn on the main computer at set times. Wondering if I can use trickle charge for Wake On LAN power to run the add-on computers even if the desktop appears powered off. Adding in a small Lion battery with a charge circuit will ensure this small computer can power itself for a while even if wall power is lost. How I Designed This OpenSCAD. Created a large block by measuring a drive tray I had for a removable hard drive using digital calipers. Also measured the location of mounting holes from this drive tray. Then, used a difference command to remove screw holes and places for the LCD, LED, and switches on the front panel. Made a hex pattern and differed that from the floor of the sled. Left To Do Make a hole in the back for power and USB connections. Add mounts for Arduino Mini Pro, RasPi 2, and Pi Zero. Add mounts for fans? Add a top that is like the bottom?
