Step 13The last soldering
Finishing touches on the PCB
I remove the wires I temporarily used to hot-wire the on/off switch and the wires I temporarily used to power the PCB.
Now I solder one wire from the PCB to the on/off switch. (not the wire going to the power on the PCB, but the wire going to the IC) On the other connection on the on/off switch I just solder a wire. (it will go to the + of the battery later on)
On the GND (ground) connection on the PCB, I just solder a piece of not-isolated wire. I push this wire along the side to the other side of the PCB and around the hole for the bolt.
