Audio playback from paper tape #MachineLearning #MLmonday #ML #Music
The Resistor Network blog demonstrates a system that exploits modern computer vision and audio compression to replace complex mechanical tape transports of the past. The tape transport is made entirely from paper and cardboard (excluding some electronics, of course) and given the name QRTape.
This is a fascinating concept to me. When considering the complete history of storage media from early cylindrical engraved records through to magnetic tape it is evident that achieving high quality and reliable data storage is both challenging and expensive. When specifically considering magnetic tape, the challenges surrounding complex mechanical tape transports and sensitive electronics highlight some of the difficulties that engineers have faced in the past.
Under the QRTape system, data is encoded by a series of QR codes that are printed on a continuous strip of paper. This strip of paper is fed from one spool through a crude tape transport, past a webcam and onto a take-up spool. The paper is advanced by a small stepper motor driven by a cheap Arduino. The rest is pure software magic.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
