MFOS Noise Toaster

The best way I can describe the MFOS "NOISE TOASTER" is this... "The MFOS NOISE TOASTER squeezes more fun out of a nine volt battery than you ever thought possible". This is an excellent project for anyone interested in synth-diy or "noise" boxes.


This is for a PCB only, suitable for multiple formats.

Introduction

The best way I can describe the MFOS "NOISE TOASTER" is this... "The MFOS NOISE TOASTER squeezes more fun out of a nine volt battery than you ever thought possible". This is an excellent project for anyone interested in synth-diy or "noise" boxes. You'll come back to it again and again due to it's portability, simplicity of operation and incredibly wide range of sound possibilities. Along the way you'll also learn a new circuit trick or two for use in your own hobby builds. Get ready to have a TON of creative, imaginative sound making fun.

 

Overview

The MFOS NOISE TOASTER circuit consists of seven main components: a voltage controlled oscillator (VCO), a white noise generator, a voltage controlled low pass filter (VCF), a low frequency oscillator (LFO), a simple AR envelope generator (AREG), a simple voltage controlled amplifier (VCA), and a one watt amplifier that drives a small speaker. The unit is powered by one nine volt battery and due to the low current drain of the LM324 (Lo-Power Quad Op Amp) it gets a lot of miles out of a nine volt battery. The circuit draws about 15mA to 25mA dependent on volume level when using the internal amp. When using line out the unit draws slightly under 15mA.
