I love how he put his own spin on this project — from the wooden enclosure, to the animatronic face that delivers the chilled beverage via a mouth tube (?!), to the Raspberry Pi-driven CRT video looper. Donald’s not just creative, he’s also great at documenting his builds. Here’s his photo journal of the project — take a look for lots behind-the-scenes details.
The guts of the project are a Trinket M0, coded in CircuitPython, peltier cooler, and perestaltic pump. Donald even created custom 3D printed clips to hold the pump tubes to his jigger and cup – great idea! He’s shared the Tinkercad model and details here.

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.
