Power cycling a whole museum of computers with Feather #ESP32 @JeffersGlass @Hackaday

Flicking a circuit breaker to power cycle hundreds of desktop computers inside interactive museum exhibits is hardly ideal. Computers tend to get cranky when improperly shutdown, and there’s a high risk of data loss.

Financial concerns ruled out commercial computer management solutions, and manually shutting down each exhibit at the end of the day is not practical. Tasked with finding a solution, Jeff Glass mixed off-the-shelf UPS (uninterruptible power supply) hardware, an Adafruit FeatherWing and some CircuitPython to get computers shut down and restarted properly.

To get the computers to wake from power loss, Adafruit ESP32-S2 Feather microcontrollers send “Wake on LAN” Ethernet packets via an Ethernet FeatherWing.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Thanks for the shout-out Anne! Since this attracted lots of “what if you” comments over on Hackaday, I’ve added an addendum to the original post addressing some of the additional ideas presented. It’s at the bottom of the original post.

    Cheers,
