13700 Dual VCLFO - Voltage Controlled LFO - DIY Modular in a Week 4.2

Day 4: LFOs (Low Frequency Oscillators) Part 2: 13700 Dual Voltage Controlled LFO (VCLFO) Difficulty: Hard Price: ~15$ MiaW playlist: https://www.youtube.com/playlist?list=PLyE56WXw0_5Q5QGMEXWmskuhojKyRdA3T PATREON LINK If you wish to support my work more than just a thumbs up :) https://www.patreon.com/SourceryOne This module turned out to be a beast to build and needed a bit of added circuitry to get the functionality I wanted. So three circuits are put together to make up this module. I use part of Electronic for Music's VCLFO 5A. Add a Scaler and offset circuit I found on electro-music.com and finally I add the LED circuit from David Hailliants LFO from the previous episode. Together A very fun and expressful module is made. There might be some parts that could have been omitted when putting them all together, but I really like how it turned out. Follow along in how to build it and make sure to check out the video with loads of example patches made with this module: Unfortunately I havent a full schematics at the time of publishing this video. I am working on getting one done, but below are links to all three of the schematics used to make this one. It is explained in the video how I connnect these three together...
