Plates & PCB

Shot of the top plate, pcb & backplate.

Same shot with the bottom of the pcb.

Soldering

Soldering station setup and ready to solder.

47 diodes soldered.

Socketing the Microcontroller

Decided to socket the microcontroller this time in case I needed to remove it or I accidently bricked it while flashing.

Another shot of the socket.

More Soldering

USB header in place.

Shot of the Mini USB header from the back.

Now its time to solder the switches. I like to start with the edges and work my way in.

Swithes used here were cheap MX style switches that came with the Contra group buy.

The Micrcontroller

With the switches soldered in place now its time to solder the leads into the microcontroller. At the advice of this post I used the diode leads cut earlier as the leads for the microcontroller since they were small enough to fit in the socket.

A shot of the leads soldered into the microcontroller.

To accomplish this I placed a strip of electrical tape over the socket so that the solder wouldnt fuse the micrcontroller to the socket and it would be removable. Then I used one of the diode leads to poke a hole for each pin in the socket to make lining it up easier. Finally I laid the microcontroller on top and places a lead through each of the 24 pins in the micrcontroller starting with the edges to line it up and then soldered them in place, cutting the extra lengths at the end.

Connecting to the USB Header

Took apart an extra Micro USB cable I had laying around to connect the microcontroller to the USB header.

Finally using a bit of Kapton tape to keep the wires from crossing and some heat shrink tubs the USB ends were soldered to the board.

Finished

A shot of the board with the top and bottom plates connected by a set of standoffs.

One last angled shot.
