those solderless prototype boards. I wanted everything on 0.1 in. centers
for easy soldering.

It was originally in the cardboard Samsung cellphone box at the left. Bert
suggested it might not survive shipping to Florida, so I moved it to the
plastic box with a clear cover. In addition to being sturdier, it lets you
see the blinking LEDs. while it is operating.

Thanks again to Bert for his kind testing assistance.
