Step 7: Wire the tags on the mini USB socket
This will take a steady hand and plenty of patience.
If you have a magnifying light, you might want to use it. Begin by applying solder to the wire and the socket individually, then put them together and touch them with the iron to briefly remelt the solder.
Holding the iron on for too long will melt the socket.
Once the wires are soldered in place, strengthen the joint by applying a little epoxy resin to the back of the socket.
