	1U Raspberry Pi NAS 3of3 (cont.) Previous phost[1]

	After I realized I could repurpose the power supply, it got my
	mind working. I decided that I would need to add 2 female USB
	ports and 2 ON/OFF switches to the case. Luckily, I had those
	items in my stash of electronic components.

	Soldering is one of those things that I enjoy doing, but it takes
	me awhile, especially since I don't do it too often. I had to
	make 2 circuits, which basically looked like this:

	+5V wire from power supply -> terminal block -> ON/OFF switch ->
	USB jack > terminal block -> -5V wire from power supply

	Since I get freaked out when doing anything electrical, I did a
	5 volt USB LED light "hello world" circuit test with an external
	USB 5 volt battery charger, breadboard, and jumper clips. Good
	thing I did since I had the pinout reversed on the female USB
	jack. Here's a pic.[2]

	After that I soldered the circuit together, crimped terminal
	connectors to the wires from the power supply, and put in the
	terminal block. Then I had to drill 2 holes in the front of the
	1U case for the 2 ON/OFF switches. Here is a pic of the switches
	mounted to the case. [3]

	For sanity's sake, I did another LED "hello world" circuit test
	with the power supply, first with a battery with AC power and then
	wall power. Another pic.[4]

	Then I mounted the 2 Raspberry Pi2's and 2 WD Pi Drives. Western
	Digital used to make Raspberry Pi drives and accessories under
	their WDLABS project, which is now defunct. I picked up some drives,
	cables, and a case during their fire sale. They had a tailor-made
	cable that allowed you to connect the Pi and the drive using 1
	microUSB cable, which is mounted in the 2 USB jacks. Here is a
	pic of the case with the Pis. [5]

	For the Pis, I used openmediavault[6] for both NAS servers, which
	I have used in the past and had no problems. Here is a pic of
	the NAS booting up when attached to mains power. [7]

	After that, I tidy'd the cabling and closed her up. Obligatory
	decals were added to cover most of the unused holes from the
	switch. I also included 2 USB extension cables to each Pi for
	attaching external storage and backups without opening the case.
	Here's the front panel pic.[8]

	Here's a pic of the 1U Pi NAS mounted in my desk. [9]

	The Pi works out pretty good for now. There are other modifications
	I would like to do, but kept those for another time. Overall, I had
	fun putting this together. I probably should take more breaks,
	especially when soldering and also remove my contacts when I solder
	since I am myopic. Good thing that Raspberry Pi 2 is good enough
	for this project since it doesn't use as much power as the newer
	Pis. I should run some tests. Also, the way I put it together
	makes it easy to repurpose if/when I need to put different devices
	in the case.
