 ===== The Plan =====
-I wanted to run a medium-duration test of the electrically-complete blinker before going through all the trouble and expense of encasing it in aluminium and glass. I decided to cast the electronics in transparent resin. This would be reasonably mechanically and chemically robust, but it would degrade in sunlight over a few years, turning yellow and crumbling. This would give me a test good enough to check for any drastic short-term problems with the electronics.

 Not too bad!
-I was reasonably happy with this result. There is some white discolouration on the solar cells visible in that photo. That discolouration wasn't present when I took the panel out of the mould. It formed shortly after I put it in the sun for this test. It seems to have been formed by some combination of:
