I spent waaaaay too much time on this project but I'm very happy with the result.

Our story begins at a Maryland hamfest in the late winter of 2016. I was attracted to an unlit alphanumeric sign. I had been looking for something alphanumeric-y to display pithy quotes, or maybe the weather, stock quotes, etc. This was priced at a solid $5 with a guarentee from the vendor that, "It worked once, I guess." Sold!

 The Radio Shack Micronta 22-124 12V, 2.5A power supply is a relatively common find at the hamfests. This power supply is usually available in the either the working, kinda-working, and broke. I bought the mostly-broke with crappy capacitors version (25 VDC output vs. the specified 13.8 VDC, with lots of ripple). The outside was a little rugged but I didn't mind that as I planned a thorough cleaning and repainting. The figures show the front and back of the as bought-unit. I paid $3.00.
