Build your own electronic instruments

Submitted by on August 30, 2010 – 8:53 pm 2 Comments

In 1979, a book written by P.K. Sood called “Electronic Musical Projects” was published that contained plans and instructions for building all sorts of DIY electronic musical devices. It’s got plans for projects for all sorts of stuff such as guitar effects, filters, oscillators, metronomes and even a simple organ.

I had a copy of the book when I was younger, and built many of the projects. Welcome to 2010, and here’s the book, converted to PDF, and all for free, enjoy:

Even if you don’t feel like building any of the projects, it’s a great read and gives some great insight into how some of the circuits work. Fascinating stuff, and because the basics of analogue circuitry haven’t really changed much, it’s pretty much as relevant today as it was back then.

    Hi, I love this book and I am hoping to build some of these project over the summer.

    I am new to electronics and all though I have a good understanding of physics and audio processing, my knowledge in electronics is very limited!

    I plan to create the guitar Fuzz Box first, in searching for all of the parts online i have been able to find everything except for the capacitors.

    There does not seem to be anywhere selling the specification in the schematic,

    Is this because the parts are out dated and unavailable now? if so is there and equivalent I can use?

    or maybe I am just not naming them the right way in my searches?

    Any help would be greatly appreciated!
