Fig.1 - placed components on the board with special attention to its placement.
2. Started with ugly solder joints... and I gradually beautified it as I learned the art of filling in the pads while keeping the solder flat. I painted on flux onto the contact pads to remove the oxidation to increase the contact and adhesion of the solder.
3. Handcrafted a beautiful bracelet. Spliced some wires, brushed flux on the ends, then held the ends together in parallel and in contact as I placed the soldering iron on there. As the wire became smoldering hot, I fed it solder. I repeated this until I rejoined the 4 pieces of wire. Heatshrink was then added.
4. A new interface was created for the power supply so that it can be used for circuit boards. This was done by cutting off the original plug and soldering on a two pin connector, and then heatshrinking the end. The power supply was then tested for continuity and shorts.
