Endless Endless Eight

It's time to launch OpenSCAD to make a dish for my spaghetti.

The main LCD of EEE is just 0.96' and it's a bit tiny to see from 1~2 meters away.
So I decided to use a trick for enlarging the display visually; a Fresnel lens.

This CRT-like shape is actuallyoriginated from the dimension of the lens I've bought.

Let's see this trick works as expected or not.

The schematic and KiCad files are available under https://github.com/likeablob/endless-endless-eight/tree/main/kicad.

Still in stability testing by leaving the breadboard circuit by the window.

It was a bit cloudy day but from the log, the device successfully has completed 6 episodes (24 min each * 6 = 144 minutes) of EE. Also based on the battery voltage observed, the battery has been charged in total eventually.
