Week 7

Not too much to report this week. Continuing from last week I finished drilling the switch board. Slight problem with a blunt drill bit that was burning the board. After replacing that, the drill did slip a bit giving me an unwanted hole in my board. Luckily it won't effect the board.
After this I continued to solder all 3 boards. The greatest difficulty was the switch board's actual switches. It was difficult to accurately line them up and solder them straight. There is some discretion between the switches. But I'm happy with the end results of all 3 boards. Visually there doesn't seem to be any problems, possibly too much soldering causing a slight blob, other than that, all connections look fine. Attached below are pictures of the results, front and back. Next week moves onto the testing of the boards.
