I had two bits of unused hardware knocking around – a Raspberry Pi that used to run my Go Free Range weather printer (the thermal printer broke – another story), and an old Samsung ML-1510 black and white laser printer that was pretty useless to me as you can’t get up-to-date Mac OS X drivers for it. The laser printer only cost me about £40 when new, but I hate seeing things go to waste.
I wondered if it was possible to glue them together – turn the Raspberry Pi into a print server that I could leave on all the time plugged into the laser printer. And, dear reader, it is possible. And incredibly easy. Using this guide: http://www.bartbania.com/index.php/cups-raspberry-printer/ I had it working in about 30 minutes.
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.
