Step 2Soldering
I built this on perfboard in a Radio Shack project box.
My usual technique for through-hole perf-board soldering is to use wire-wrap to make the connections, then to solder the wire-wrapped connections. The thick black wire wrapping around the board is the antenna.
The first picture shows the back of the board, where the connections are made. The second shows the front of the board, inserted into the box with the connections to the off-board devices (switches, LED, and binding posts) made.
