[5V] Power to the People! [Part 3]

This is a three part article

To kick-off this third and final thrilling episode in ‘The Electrification of The Herman Union’, I added the final connectors on the outside of the cigar box. Seeing as I had only four USB ports but a 6-Fuse fuse-holder, that left me two fuses to play with. So I decided to add a couple of nice Dr. Frankentstein screw-terminals, fed directly [well, through the fuses] from the main leads, so I’d have a couple of 12V outputs on my powerboard too. I found this nice wee panel off an old HiFi in one of my “Things That Might Come in Handy” boxes and mounted it on the lid of the box.

As you can see from the above piccie, we’ve still not completed the USB circuits; the 5V output is connected to the USB sockets and the 12V input is connected to one side of the fuses. So, next job was to connect jumper leads from the main 12V cable to the other side of each fuse.

And then solder these jumper leads onto the 12V main cable and, of course, give the whole thing another mighty dollop of heat glue, to stop anything coming adrift.

I also did likewise, connecting all the earths from the voltage converters, USB sockets and screw terminals to the main earth cable.

So, with all my leads soldered in place, all sockets and terminals attached and everything slathered to within an inch of its like in heat glue, this is what the inside of my power panel looked like. I did start to worry that I wouldn’t be able to get the cigar lid box closed!

With a bit of cunning Origami work on the various cables, however, I managed to get everything to fit inside the box and to close the lid. With all that gloopy chaos hidden from view, the board looked a bit more presentable.

So there you go. One SteamPunk powerboard, supplying 4 x 5V USB sockets and 2 x 12V screw terminals. Job’s most indubitably a ‘Good ‘Un’!
