Hey friends, we’re back again with more stories to tell. Today we’re going to discuss the PF3000‘s insides, which isn’t

Build a multi-tone DJ board using a Raspberry Pi Pico, a few inexpensive components, and drag and drop files! This lesson will show you how to use a Raspberry Pi Pico configured to run CircuitPython, along with a low-cost Adafruit Cowbell (to hold gigabytes of sound & provide a STEMMA-QT port), plus an MPR121 12 pad capacitive touch sensor to create a DJ-style board that will play sounds when a finger is held on a touch point. A great classroom example, fun and funky build, with everything you need at the repo: https://github.com/gallaugher/pico_12_pad_dj_board If you don't have a pico configured for CircuitPython, you can find a tutorial on how to set this up at: https://bit.ly/pico-school Part of Prof. John Gallaugher's university course: Physical Computing: Art, Robotics, and Tech for Good. EVERYONE (including teachers) are welcome to use this with their own courses. Just PLEASE let me know so that I can tell if I'm having an impact.

Mjolnir, also known as Thor’s hammer, is a discerning thing, at least if you believe the modern Marvel canon. [alemanjir] decided to build a semi-functional replica that makes judgement calls of its own, though they’re perhaps a little less thought-out than the storied hammer of legend. The build consists of a 3D-printed hammer prop, inside of which is a Raspberry Pi Pico microcontroller running the show. It’s hooked up to a MPR121 touch sensor that detects when someone grips the handle of the hammer. At this point, the Pico makes a pseudorandom “worthiness check” as to whether the holder is righteous enough to wield the hammer. If they are pure of heart, it unlocks a magnet which frees the hammer from whatever metallic surface it might be stuck to. [alemanjir] also included a little additional functionality, with the hammer playing various sounds when swung thanks to a speaker and a ADXL345 accelerometer secreted inside. One wonders whether the electromagnet inside is strong enough to hold out against an unworthy person lifting it from the ground. While it’s perhaps not as powerful or as decisive as the mythical object, it’s nonetheless a fun learning project that likely taught [alemanja] some useful basics of embedded development. We’ve featured some terrifying takes of the Mjolnir prop before, too, like this shockingly high voltage version. Video after the break.

Upgrade from a simple mallet to this soft touch Xylophone. Duruo on Instructables created this Capacitive Touch Xylophone using a Raspberry Pi Pico, a Adafruit 12-Key Capacitive Touch Sensor Breakout – MPR121 and a bunch of solenoids. This is an adaptation of Adafruit’s Robotic Xylophone When you touch the conductive fabric on the touchpads, the […]

Does anyone remember me tweeting about to have made some “python to nodejs subprocess” tricks? Well it did work but two processes on one i2c-bus is nothing linux likes too much. So here we go: A...
