The Simple LFO is a… simple LFO module for your Eurorack system.
Two waveforms available: Triangle and Square wave. Adjustable amplitude and Low/High range switch.
It’s easy to build, easy to understand and maintain. Only easy-to-find through-hole components.

Simple VCO
Following the Simple LFO module, here comes the Simple VCO.
It’s a very stripped down version of the Formant VCO, modified and adapted to the Eurorack format.
This circuit is also present in the VCO section of the DM77 Drum Module.
The Simple VCO is 1V/Oct capable. In order to reduce the number of parts, only one waveform output is available.
The result is a super simple module, easy to build, to understand and maintain.

Simple LFO 1.3
I released a new update of the Simple LFO, now in version 1.3.
The update is mostly about how the LED blinks.
Simple LFO 1.2
This is an update of the Simple LFO module.
The major improvement is the implantation of an amplitude potentiometer on the PCB.

Simple LFO: New Documentation
I’m working on improving my projects’ “documentation and build instructions”.
This is the next update:
This is an outdated version, an update is available!
Simple LFO update 1.1
New revision for the Simple LFO. It’s mostly a slight improvement of the output stage.
I added an buffering opamp on the output. Now, the output load doesn’t affect and modify anymore the signal frequency.

Simple LFO Kit
A small kit is available for purchase! Check the “shop” page.
In the Kit, you will find the following:
Resistors, 16mm potentiometer, connectors, capacitors, IC and its socket.
Currently, no faceplate available. You want one? Tell me!
I made a double front panel for 2 LFO modules. It’s available for purchase. Contact me.
This is an outdated version, an update is available!
