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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
