Here is a prototype of some kind of Arduino Punk Console based on the sketch of Beavis Audio.

It's not finished yet.

Soon...

Co41D 2020 MIDI Theremin Sounds Pretty Sick

As the pandemic rages on, so does the desire to spend the idle hours tinkering. [knaylor1] spent the second UK lockdown making a sweet Theremin-inspired noise machine with a low parts count that looks like a ton of fun.

It works like this: either shine some light on the photocells, cover them up, or find some middle ground between the two. No matter what you do, you’re going to get cool sounds out of this thing.

The photocells behave like potentiometers that are set up in a voltage divider. An Arduino UNO takes readings in from the photocells, does some MIDI math, and sends the serial data to a program called Hairless MIDI, which in turn sends it to Ableton live.

[knaylor1] is using a plugin called TAL Noisemaker on top of that to produce the dulcet acid house tones that you can hear in the video after the break.

If you’ve never played with light-dependent resistors before, do yourself a favor and spend a little bit of that Christmas cash on a variety pack of these things. You don’t even need an Arduino to make noise, you can use them as the pots in an Atari Punk console or make farty square waves with a hex inverting oscillator chip like the CD40106. Our own [Elliot Williams] once devoted an entire column to making chiptunes.

ATPC - Synthesizer Kit - ATtiny Punk Console from krautmovies on Vimeo.

noisio.de/ This is the ATtiny Punk Console (short ATPC). It's an easy to build synthesizer-kit based on the ATtiny85 microprocessor which is one of the smallest but also powerful members of the ATMEGA family (you probably already know by Arduino). The ATPC squeezes out the most of this little beetle. The synth is equipped with 4 potentiometers with body-contacts to tweak the sound. It's powered by center negative plug or 9V battery. You can trigger events by a push-button or via the programmable sync in- or out line. On the output side you'll find a variable lowpass filter and a volume controlled buffer stage to push out true 8bit sound. Because of the parallel 3.5mm and 6.3mm jack plugs you are able to link them in line as well as to interconnect and synchronize with other gear.

Programmable Wrist Synth Pushes The Envelope

Synths are a ton of fun no matter how good or bad they sound. Really, there are no bad-sounding ones, it’s just that some are more annoying to listen than others to if you’re not the one making the beep boops. [Clem] had built a tiny LDR-based synth into a watch case a few years back and took it to many a Maker Faire, where it delighted and annoyed until it ultimately broke.

Naturally, it was time to make a new version that’s more capable. Whereas the first one was Atari-punk-console-meets-light-Theremin, this one has a bunch of inputs and can be programmed on the fly to record and play back bendable tones. It’s driven by an Arduino MKR, and the inputs are managed by an impressively squash bug-wired shift register. [Clem] used beefy switches this time in the hopes that this one will last longer. We think the slide pots are a great touch, as are the candy-colored knobs printed in PMMA.

Our favorite part is that [Clem] took advantage of the random states the microcontroller pins are in when it’s first powered on. If you don’t want to program any notes, you can use the ones generated at boot and just play around with those. Be sure to check out the build video after the break.

We’ve seen our share of synths, but few as delicious-looking as KELPIE from this year’s Hackaday Prize.
