Really, been working like a dog. Six days a week, averaging twelve plus hours a day. Definitely takes a toll. English not so good.
The Wif and I wandered about then Saturday as we ate wont to do somedays, and stopped in at Ada. Amongst my other treasures, I got a bag of candle-flicker LEDs.
This morning, which I only wire about now because I’ve been driving to work, I realized I could make a wicked wall since with them.
Note I’m trying to decide if I go discrete components for an elegant solution or run them with a Photon, for extensibility. I think I should go discrete for elegance and Science! and then whip out one with something like a Photon for (practicality?).

I’ve now had done sleep. Taking the bus today because the Wif needs the car to pick up our new kitteh.
Basically, for the discrete version:
Solar cell fills cap (probably nationalized from an old power supply), when light level goes low enough a photoresistor triggers a transistor and we start discharging through the LED. I have everything I need but the solar cell.
