Step 3Sanding down the circuit

Sanding down the circuit

As stated, the circuit was too big for the case, so I needed to reshape it a little. I figured I could do the following:
- Sand down the edges to remove excess
- Add on a few link wires so I could cut off the end of the circuit
- Move the awkwardly positioned headphone socket

To start, I sanded down the easy bits just about as much as I could. Saved at least two milimetres. I then basically cut away all of the circuit that supported the USB port so I could push it through further and save more space. Eventually I got one end to fit in.

It's pretty hard to get any pictures of my messy link wire(s), but I managed to cut quite a bit off there too. And desoldering a surface-mount mini headphone socket... that wasn't nearly as easy as I'd expected. It eventually came off, with a lot of poking, driling, prying and sucking up solder.
