After my assembling my first iteration of the heart base, a few issues surfaced.

1. The perf board was raised above the rest of the heart base. I decided it was a much better idea to recess the perf board into the base so that the top sits flush with the rest of the base.
2. In order to test the fitment of the heart pieces, the heart base needed to have some kind of wall around the outside. So, I put a small lip around the outside for the pieces to have a place to drop in!
3. I made the slots for the underside of the pins larger to make it easier to solder to the pins.
4. Probably a few other minor tweaks that I can't remember.

Along with the heart base, I soldered an LED to the pin contacts to test the connection. In this picture you can also see the raised lip and recessed perf  board.

Exciting things are coming in the next log!!!
