Creatiive Technologist ◆ Analog Audio ◆ Producer

I design embedded systems, analog circuits, and RF electronics by day — and record music by night. Based in the Netherlands. I believe the most interesting work happens at the intersection of the technical and the expressive.

P1 - ANALOG AUDIO PROJECTS

Low Frequency Oscoillator

A LFO based on Electric Druid's STOMPLFO designed for Eurorack systems. It outputs 8 waveforms with a frequency between 0.05Hz-25Hz.

View Full Project

The LFO is built around Electric Druid's STOMPLFO and it can output 8 different waveforms, including 2 random waveforms(slope and levels). It can output these signals at frequencies between 0.05Hz and 25Hz, it has amplitude control, and offset control. It has a 3.5mm mono output and it needs a 5v supply.

This project is ongoing. In the future I will add a panel for the potentiometes and the 3.5mm output and add a eurorack compatible power supply connector board.

AS3340 VCO

An implementation of the Electric Druid's Voltage Controlled Oscillator(VCO) AS3340.

View Full Project

The frontend LNA is designed around a BGA2803 MMIC amplifier with a measured noise figure of 0.9 dB and 21 dB gain across 100 MHz–2 GHz. The PCB uses Rogers RO4003C substrate (Dk=3.55) to minimise dielectric loss at microwave frequencies, with coplanar waveguide traces impedance-matched to 50 Ω.

Modular Synthesizer VCO

Eurorack-format voltage-controlled oscillator with triangle core, waveshaper outputs (sine, saw, square, sub), hard/soft sync, and precision 1V/oct tracking using tempco resistors.

View Full Project

The oscillator core is a triangle-core design using a precision integrator built around a TL072 op-amp with a matched transistor pair (THAT340) forming the exponential converter. Tempco compensation is achieved using a 3300 ppm/°C resistor (NTCLE203E3) in the V/oct scaling network, yielding <2 cents drift over 0–50°C.

Waveshaping derives sine from triangle via a diode-ladder wavefolder, and square via Schmitt comparator with variable pulse-width modulation (±5V CV input). Hard sync resets the integrator on the rising edge of the sync input; soft sync inverts the ramp direction. Sub oscillator is a flip-flop divider for -1 oct square wave output.

The PCB is designed in KiCad 7, with a controlled-impedance audio path and star-grounded audio/power domains. The ±12V Eurorack power rail is filtered with a pi-network LC filter per rail. All potentiometers are Alps RK09 series; jacks are Thonkiconn. Panel is 14HP aluminium, laser-etched and anodised matte black.

Tracking accuracy: ≥10 octaves within ±2 cents after trimming. Total cost of BOM: ~€38. Schematic and Gerbers available on GitHub.
