MIT Media Lab have developed the new and improved Knitted Keyboard II using electrically conductive, capacitive and piezoresistive fabrics and fibers.

The Knitted Keyboard II, from Irmandy Wicaksono and team, is a multi-modal, soft and stretchable e-textile musical interface. It responds to touch, including keystrokes, pressure, squeezing and pulling, and continuous proximity, such as hovering and waving. This means that you can play it in a range of ways: like a keyboard, a theremin or as something that is a mixture of the two. You can even wear it like a scarf.

MIT’s Knitted Keyboard II runs on a Teensy 4.0 and uses five MPR121 proximity/touch controllers. It uses MIDI and can therefore sound like any software instrument you have access to, making it incredibly versatile.

Check out Hackaday’s coverage of the Knitted Keyboard II or read the MIT project overview for more detail on this project.

The Audio shield is on sale for Black Friday (sale has ended), with sockets and a flash memory chip included.

 

Hardware hacker Hypothete has hooked up a Teensy 4.0 to an analog TV, to display JPG and PNG images in the NTSC video format.

The cozy hackerspace Ctrl-H in Portland runs an event twice a month called DorkbotPDX, which is where Hypothete came to show off Teensy TV, their super cool analog TV hack. The Teensy TV is made up of two parts: a Teensy 4.0 running an Arduino sketch, and a Node.js server sending data to the Teensy.

The whole project has been written up over on Hypothete’s GitHub, including wiring instructions, code and reference links if you want to dive further into the world of analog video hacking.
