The GfxHax drink shield is an Arduino shield that converts an arduino into an Open Source Breathalyzer. It come complete with a light bar to show the intoxiciation levels. There is a series of 11 lights down one side of the shield that go from green to yellow and ultimately to red. There are also player ready lights. Why are there player ready lights? Well, this is because the shield is not just a standard Breathalyzer but can be used as a party game. With the GfxHax drinkShield you also get a GPL game that lets you play with your friends and keep highscores! This software is licensed under the GPL so you can add features and will have unlimited free updates to new versions.
The drinkShield itself is licensed under the Creative Commons license and is free to modifications. The libraries and Source code are licensed under the GPL or public domain. It comes as a kit and is a really fun starter project to those just learning how to solder. This kit is specifically designed for Hackerspaces around the world. A hackerspace can host a class and afterwards celebrate by throwing a party! We offer bulk discounts on the web for classes wanting to buy kits.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
