Build an “Internet of Things” connected mini printer that will do your bidding! This is a fun weekend project that comes with a beautiful laser cut case. Once assembled, the little printer connects wirelessly to get Internet data for printing onto 2 1/4″ wide receipt paper. Based on a Raspberry Pi computer, this is a powerful mini Linux machine. We have example Python code for a few different printouts, including a daily weather forecast report, Sudoku puzzles, an image printer, and a Tweet-printer that connects Twitter’s search API and retrieve and print tweets according to your requests: you can have it print out tweets from a person, a hashtag, mentioning a word, etc! All the code is open-source and written in Python, so it’s easy to adapt and write your own custom printer software.
The project is based on Raspberry Pi, and while it’s not a very complex project soldering-wise, it does require a little simple soldering and assembly. This project is good to take on if you’ve set up a Raspberry Pi computer before and know how to run commands on your Pi.

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.
