As a huge Korg fan I got to put together an Ensemble piece using 1978 era Korg Synths. The hero is the mighty PS3200 polyphonic synth playing homage to its big brother (and, as of 2024, soon to be re-released by Korg, the PS3300) by using the direct out of the 3200 into a MAM RS3 Resonator which recreates the famous PS3300 & 3100 modulated resonator circuit. The 3200 plays pads, base and noises.
Lead lines and extra pads via an MS20 into a VC10 Vocoder combo give a haunting breathy sound.
The SQ10 Sequencer drives the MS50 and MS20 synths for a rhythmic sequence and the MS ..read more

This is my index for all coffee related stuff.
I'm mainly interested on Coffee Lever Espresso machines.
These I think are most closely related to analog.

If you want good tasting espresso for whatever coffee drink you're making
dialing in your coffee is absolutely crucial . The aim is to get a good brew recipe.
This post's focus is mainly on the time factor.
You need to do this whenever you have a new bag of beans.
(even if you're using the same coffee from the same roaster as last time).
Getting a good coffee is a bit like getting a good golf swing.
Repeat, repeat, repeat. Try to reduce variables. get consistency.
The three parts to a recipe are:
1. Dose
2. Yield
3. Time
My simplest coffee machine is a Breville Bambino.
I think ..read more

These are my build notes for the circuit benders clone of the Roland/- Boss Dr 55 drum.
The clone is called the CB-55.
The original is a really simple and great sounding machine. It's definitely a classic.
I think where it falls short is it's limited sequencer, and that its tricky to sync to external gear.
I loved the first DR-55 I bought so much, that I purchased a second one with the intention to mod it.
But I just couldn't vandalize it .
Mods to overcome this are out there but I think its a shame to need to mod vintage gear.
These relics are getting harder to find as the ..read more

These are my build notes for the nonlinear circuits LDRama module.
tHIS eurorack 28HP light sensor module was designed upon suggestions from Alex Brunori.
The idea is to play a video (or skype or whatever is the newest thing) fullscreen on your phone and place the phone on the LDR array. The module will generate CVs in response to what is happening in your video.

I think this is a pretty neat idea.
It is designed to suit a typical 5x2 inch screen, larger screens work fine tho some info around the edges is lost. Ideally the module will sit flat, if ..read more

These are my build notes for the nonlinear circuits "stochaos" module.
It's a 8hp eurorack.
STOCHAOS...... It's a random rhythm pattern generator or sequencer which produces gates and control voltages
There are just two inputs ; IN & RST
Everything else is an output

Some notes on how to upload a hex file using AVRdude.
AVRdude is a program to upload or download to on-chip memories of Microchips AVR suit of Microcontrollers.
Ill use a

These are my build notes for the Nonlinear Circuits "Beat Freqs" module
Its eurorack format.
The BEAT FREQS has gates ... lots of gates .... use it as a chaotic gate sequencer/event generator.
Its great for driving drums
This module is based on an earlier one:
82. Beat Freq - build notes - part 1
Beat Frequency - NLC - Build notes - part 2
The original had CV inputs, pots and an XNOR output.
This new "improved" version gets 12 extra gate outputs and a lot more flashing LEDs.

These are my build notes for the Nonlinear Circuits CMOSC module
Its a eurorack format module.
CMOSC is an updated version of the
4U CMOSC (CMOS drone Oscillator).
Each module has 6 oscillators; the frequency of each
oscillator can be set with the pots. Feeding a signal to
input will decide which oscillator signal will appear at the output. If the signal is low, oscillator A is heard, if the
signal is high oscillator B is heard.
This module gets very interesting when the outputs of each oscillator pair are fed into other pairs, which are themselves controlled ..read more
