Australian software engineer Sarah Spencer has taken a Raspberry Pi and an Arduino-compatible board and written some PHP and Python code to interface to hack a Brother KM950i knitting machine. The resultant set-up allows her to send an image to the machine over her network with more than two colours in any single row of knitting. Her latest project, Stargazing: A Knitted Tapestry, measures 4.6 metres (15 feet) wide and 2.8 metres (9 feet) high and was displayed at, and was funded by, recent geek festival EMF Camp .
The work had been embedded with LEDs that lit up constellations. You could request a light-up from a website which was then sent over to the tapestry. I’m not sure if this involved a Pi too, but either way it was very clever, though non-functioning when we visited.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
