A story is really short: friend asked me to design a mixer/sync splitter which could fit between 2 3PO Pocket Operator cases from Dich Studios, so he can set the output level of each Operator separately. The cooperation was 100% remote and e-mail based, so it was very interesting experience for me. The plan […]
The purpose of my passive volume control build was simple – I just needed an analog regulation of headphones loudness my laptop was missing (and nothing feels better than a potentiometer knob in your hand). This project was so incredibly boring, that at first I didn’t want to write about it. However, apart from its […]
What a great click bait title! And in fact, true! Volca Modular specs in Korg’s manual are not exactly precise, but this is actually a good news. Let me explain: Korg made a great and much explaining manual, but (IMHO) for sake of easiness of understanding, some specs were simplified. Who wants to interact with […]
A friend (the one who menaged to kill few pairs of speakers with my Binaural Beat Generator) asked me if I could add an CV input to his cassette recorder, so he could use it with his modular synth. The answer was: “Yes”. The mod was preformed in a unusual “engineer way”, not the nowadays popular […]
As far as I remember, Glidophone was one of my first synth projects (May 2012), somewhere around Stylophone clone and Atari Punk Console. And as some of my early synths, it failed to generate any sound. I tried to resurrect it around 2016, but I was unable to find an error. Finally it ended in my […]
4sum is a simple, monophonic portable audio mixer with 4 inputs and 1 output with separated level controls for each channel. I designed this one for one reason: I did not have any mixer for my Monotrons and other “toys”! (Now you can get it at patch.audio). The design The best way to design something […]
Stay calm, this is simply the beginning Durning my early synth DIY days I made a lot of simplest stuff – all kind of “beginner friendly” projects. They were cool devices to make, but after an initial exciment phase, a reflection came – they make some bleep sound and thats it :/ (It think the […]
This a story about squeezing 16 kg of pure analog goodness into childs keyboard. Introduction For a long time i was thinking about modifying some small, cheap toy synth. I wanted to possess an unusual, battery-powered device with a built-in speaker, so I could play in a spare time. Initially, I wanted to make a […]
Stylophone is a portable, miniature sound synthesizer, designed around 1967 and build between 1968 and 1975. In 2006 it was put on market again, with some major modifications. Its most recognizable feature is a way of play – musician uses stylus and a metal keyboard. The similar instruments are Gakken SX150 and Dr Bohm Hobbyton. […]
MFOS Echo Rockit is an small, portable synth / effect processor. The original project can be found on www.musicfromouterspace.com and belongs to Ray Wilson. The device is somehow similar to Korg Monotron Delay, but it has more modulation options. In my construction I have added amplifier with small, but very pugnacious Visaton speaker. In small […]
Resonance mod, LFO to cutoff modulation mod, if you are into Monotron Delay modding you have probably done it or at least know it exists. I wanted to go step further (and keep Monotrons sexy size). Introducing: Monotron Delay Implant! What is implant? It is an additional mini PCB, containing opamp and some passive stuff […]
Every electronic engineer in his life have to build: a strobe light, a clock, adjustable LM317 power supply and guitar effect. I build all previous devices and only effect left to make. I decide to build SansAmp GT2 overdrive – I don’t own a guitar, but I like the hardcore style disorted bass drum sound. […]
I can barely remember when I started this project… After I build Atari Punk Console I decided to build similar 2-knob device. The idea was very blurry – small music box, powered by 9V battery, easy to use and fun. This is how it started and how it is ended. This is the story of […]
Intro Prices for this deadly device starts from 25$ (!)(*) and according to some descriptions, it’s intended for intermediate DIYers (!!). It is a popular project and, i must say, at first sight I thought it is very trashy. One chip, two potentiometers – not very finesse, but I decided to give it a chance. […]
