I'm selling small optotronics system which includes few modules:

modules include: 1) CEM3340 dual VCO 2) Rungler 3) wavefolder 4) OTA VCA 5)basic dual LFO

purchase in my etsy store: link

detailed documentation of each module: link

(except for the dual LFO, super basic triangle/square outputs, no external CV input)

quick little demo of the quantum defrakulator

Part 1 of my series about the “F_Series”, a bundle of modules forged after the legendary DIY modular synth “Formant” (the 1977/78 Elektor project) in Voltage Modular is online now:

From time to time I dive into electronics and try building something interestingly sounding. This time it became a drone machine based around the CD40106B Hex Inverter and a TL074CD quad op-amp. Pretty happy with the cinematic noisy landscapes that comes out of it.

I Feel like making / building a new prototype synth again - This was built in 2017 and the sounds from this was used in making the album - Sanathana & Sanhata : i - This was quite a task and my first ever build! Quite a lot learnt in the process of making and moving ahead I have some good ideas to make an all in one synth with synth voice (perhaps 4 oscillators minimum), sequencer, envelope generator, Lfo’s, Clock Dividers and Multiplication, sequential switch and a digital effects section if possible all in one! - #prototype #synth #diy #diysynth #synthesizers #synthesizer #personalised #mysynth #bananacables #analog #analogsynth #analogsynthesizer #analogsynths #music #instrument #electronic #circuit #circuitbending #electronicmusic #technology #tools #musicaltool #innovation #creative #engineering #science #passion #love #life #peace https://www.instagram.com/p/Cn_XTdNI4-h/?igshid=NGJjMDIxMWI=

fulfilment has been achievement ! pure joy! all of the chakras have been activated! and no, this is not an awkward picture ;)

well done everyone!!!

I built my first MIDI controller - a budget version of the “MIDI Fighter” 🤺 Had lots of fun learning how to make this from scratch and it has inspired me to continue exploring the world of DIY Electronics and music instrument design ✨ … #midicontroller #arduino #arduinoproject #musicinstrument #diyelectronics #electronics #diysynth https://www.instagram.com/p/CUrzIjcF4z_/?utm_medium=tumblr

been working on this sampler for the last year. finally got inspired to somewhat finish it. its made out of a wood box, axoloti core and a broken old keyboard. its 8 samplers that each have an individual rate control and master pitch and stretch knobs. plus some effects. hope to share some more stuff, and more in detail videos about the melo-8. hope you get inspired.

okey thumbnails aside, here's a tutorial THAT I SPENT WAYYY TO LONG ON. that will help you all with your toner transfer graphics.PLEASE RECOMMEND ME SOME VIDEO EDITING SOFTWARE, I think Microsoft photos almost killed me.

Triangle VGA sequencer is an unorthodox audio-video synthesiser. It consists of arduino for generating VGA signal, bunch of CMOS chips like: shift registers, frequency dividers, bilateral switches and phase locked loops. It’s noisy, unpredictable and very glitchy! It also contains envelope follower, so you can plug in an external input. There are no rules in playing the triangle – the surface is magnetic, which allows you to combine variety of patterns via placing the magnets, create feedbacks between each colour/oscillator and unstable sequences. It contains two outputs – red and green, while blue controls the overall pitch of the sequencer. It has on / of toggle switches for each colour/oscillator as well as for their frequency range and three sliders for their frequency and controls for vertical and horizontal sync and clock oscillator. It has VGA output and runs on USB mini. What you see is what you hear ! It’s brute, it’s rude. it’s contingent and crude!

soon workshop at Iklectik, London.

I´ve reached the next phase of making a DIY VCO. It´s still prototyping, but after testing the circuit on the breadboard it´s time for a mechanically more stable version on Veroboard.

I have been using few behringer products over the years. Some of them I have sold but others are still part of my setup. But since I have heard about this one, the craving is almost uncontrollable. #singersongwriter #homerecording #behringer #synth A good alternative to #diysynth ?
