# Chilled Drinkibot ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/047/916/medium800/temperature_PB020235_2k.jpg?1509684725) On a hot day, what's better than a nice cold beverage? Nothing, that's what! Here's a fun way to make made-to-order chilled drinks without using ice (which can dilute things), the Chilled Drinkibot! The Chilled Drinkibot is a thermoelectric cooler that uses a Peltier cooler, a large heat sink and fan, and a small pump to chill and then deliver your beverage to your waiting glass. It uses a Trinket M0 running CircuitPython to control things, and a temperature gauge to display your final chill value. https://youtu.be/NOPRsvilm2I ## Parts and Materials In addition to the parts listed below, you'll also need a small conductive cup, preferably copper or something silver plated, and material to mount the components. This can be a plastic project box, 3D printed PLA, laser cut acrylic, or anything you like, really! Just so long as we can keep the electronics up above the liquid, and the Peltier cooler fan elevated for airflow. ### Part: Adafruit Trinket M0 quantity: 1 for use with CircuitPython & Arduino IDE [Adafruit Trinket M0](https://www.adafruit.com/product/3500) ### Part: Peltier Thermo-Electric Cooler quantity: 1 Module+Heatsink Assembly - 12V 5A [Peltier Thermo-Electric Cooler ](https://www.adafruit.com/product/1335) ### Part: Panel Temperature Meter quantity: 1 -30 to +70 °C [Panel Temperature Meter](https://www.adafruit.com/product/576) ### Part: Peristaltic Liquid Pump quantity: 1 with Silicone Tubing [Peristaltic Liquid Pump ](https://www.adafruit.com/product/1150) ### Part: Illuminated Toggle Switch quantity: 1 with Cover - White / Clear [Illuminated Toggle Switch](https://www.adafruit.com/product/3308) ### Part: Rugged Metal Pushbutton with White LED Ring quantity: 1 16mm White Momentary [Rugged Metal Pushbutton with White LED Ring](https://www.adafruit.com/product/558) ### Part: 12V 5A switching power supply quantity: 1 12V 5A switching power supply [12V 5A switching power supply](https://www.adafruit.com/product/352) ### Part: Female DC Power adapter quantity: 1 2.1mm jack to screw terminal block [Female DC Power adapter](https://www.adafruit.com/product/368) ### Part: 5V 2.4A Switching Power Supply quantity: 1 with 20AWG MicroUSB Cable [5V 2.4A Switching Power Supply](https://www.adafruit.com/product/1995) ### Part: N-channel power MOSFET quantity: 2 30V / 60A [N-channel power MOSFET](https://www.adafruit.com/product/355) ### Part: Heat Sink Thermal Tape quantity: 1 3M 8810 - 80mm x 80mm [Heat Sink Thermal Tape](https://www.adafruit.com/product/1468) ### Part: Adafruit Perma-Proto Half-sized Breadboard PCB quantity: 1 Adafruit Perma-Proto Half-sized Breadboard PCB [Adafruit Perma-Proto Half-sized Breadboard PCB](https://www.adafruit.com/product/1609) ### Part: Black Nylon Screw and Stand-off Set – M2.5 Thread quantity: 1 Black Nylon Screw and Stand-off Set – M2.5 Thread [Black Nylon Screw and Stand-off Set – M2.5 Thread](https://www.adafruit.com/product/3299) ### Part: USB cable - A/MicroB - 3ft quantity: 1 USB cable - A/MicroB - 3ft [USB cable - A/MicroB - 3ft](https://www.adafruit.com/product/592) ### Part: 1N4001 Diode quantity: 1 10 pack [1N4001 Diode](https://www.adafruit.com/product/755) ### Part: Adafruit Parts Pal quantity: 1 Adafruit Parts Pal [Adafruit Parts Pal](https://www.adafruit.com/product/2975) Primary: You can watch the live build in these two episodes of John Park's Workshop Live. https://youtu.be/zn5ZdfYp7nM https://youtu.be/0U283AQ7qFQ - [Next Page](https://learn.adafruit.com/chilled-drinkibot/build-the-circuit.md) ## Featured Products ### Adafruit Trinket M0 - for use with CircuitPython & Arduino IDE [Adafruit Trinket M0 - for use with CircuitPython & Arduino IDE](https://www.adafruit.com/product/3500) The Adafruit Trinket M0 may be small, but do not be fooled by its size!
