ZeroLiPo: Pi push-button battery power control

The ZeroLiPo is a Lithium-ion Polymer battery power manager for the Raspberry Pi from Pimoroni.

It does not handle battery charging, it simply converts the LiPo 3.7Volts to 5Volts, and provides a low voltage alarm.

Although I've had one of these for ages, I've only just considered using it, possibly for my Bat Call Logger.

Pi Unicorn Hat: as a photographic strobe light

This Hat sits on a Raspberry Pi and contains 64 LEDs in an 8 x 8 grid format.

The documentation says that the LEDs are very bright "...bright enough to cause eye pain... possibly retina damage..." ...so I wondered if they had a use in photography.

This post details some experimentation, some Python code, and a few photos.
