The next module is on the breadboard. I’m fiddling with these SMD audio transformers for a ring modulator. Looks good so far! #eurorack #synthdiy #synth #analog #ringmodulator

ChatGPT making things up about the article:
This article from Guitar World highlights some of the many different ways extreme metal guitarists have utilized ring modulators. It discusses a range of classic riffs, as well as some rarer tours de forces, from seminal extreme metal bands such as Meshuggah, Municipal Waste, and Slayer. The article goes on to discuss the unique sound and textures these effects can achieve on the guitar, as well as the skill and creativity needed to use them well.

@arturo182 I've done several music machines this year, but some were started last year. One that I did in January 2022 was a swell ring modulator pedal. Inputs can also be VCO outputs.

It's called the Purple Ring as it uses purple LEDs (and painted case)

I saw someone who has just built the #RingModulator kit from #tnmoc

What kind of power supply does that need?

Sound and Light Play off Acrylic and Wire in This Engaging Circuit Sculpture

It's no secret that we really like circuit sculptures around here, and we never tire of seeing what creative ways people come up with to celebrate the components used to make a project, rather than locking them away in an enclosure. And a circuit sculpture that incorporates sound and light in its design is always a real treat to discover.

Called "cwymriad" by its designer, [Eirik Brandal], this sound sculpture incorporates all kinds of beautiful elements. The framework is made from thick pieces of acrylic, set at interesting angles to each other and in contrasting colors. The sound-generating circuit, which uses square wave outputs from an ESP32 to provide carrier and modulation signals for a dual ring modulator, is built on a framework of tinned wires. The sounds the sculpture makes have a lovely resonance to them, like random bells and chimes that fade and mix together. There's also a matrix of white LEDs that form a sort of digital oscilloscope that displays shifting waveforms in time with the music.

While we like the way this looks and sounds, the real bonus here is the details of construction in the video below. [Eirik]'s careful craftsmanship working with multiple materials is evident throughout; we were especially impressed by the work needed to drill holes for the LED matrix, any one of which slightly out of place would have been painfully obvious in the finished product.

This is far from [Eirik]'s first appearance on these pages. His vacuum tube and silicon "ioalieia" was featured just a few weeks back, and "ddrysfeöd" used the acrylic parts as light pipes in a lovely way.

A CMOS Ring Modulator Pedal

Earlier this year, we featured an unusual radio receiver that took the very traditional superhetrodyne design and implemented it in an unexpected fashion without any inductors, using instead a combination of 74HC logic chips and op-amps. Its designer [acidbourbon] remarks that the circuit bears a striking resemblance to a ring modulator,so has taken it down that path by producing a 74HC based ring modulator guitar pedal.

In both circuits, a 74HC4046 phase-locked loop chip serves as an oscillator, driving a 74HC4051 analogue switch chip that performs the mixer task. The extra-op-amp filter and demodulator circuitry from the radio is omitted, and the oscillator frequency moved down to the audio range. The result can be heard in the video, and we probably agree with him that it's not quite the same as a classic ring modulator. This lies in the type of mixer, the diodes used in a traditional circuit have a forward voltage to overcome before they start or end conducting, while the CMOS switch chip does so immediately on command.

The 4000 series CMOS and their descendants are a fascinating family with many unexpected properties that our colleague Elliot Williams has gone into detail with for his Logic Noise series. Meanwhile take a look at our coverage of the original radio.
