I have rebuilt my MySQL server system using a Pi version 2 and a new external hard drive. I did this one in a Linksys router case. These cases are really easy to work with and not hard to come by.
I skipped the USB hub on this build. There isn’t enough room and I found an easier way. Power is spliced directly into a usb cable from a connector on the rear of the case. I found that this would not backfeed the Pi like I expected. (This does work on some of my older Pi systems.) To overcome this, I added a wire feeding 5V into GPIO pin #2.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
