DIY AUDIO ELECTRONICS READING LIST:
This is a list of texts/resources that have been helpful to me; including direct links wherever possible and small annotations.
Handmade Electronic Music - Nicholas Collins: http://loliel.narod.ru/DIY.pdf
The bible. Extremely comprehensive and easy to comprehend treatise by a real guru. This one has a huge array of projects and will keep you busy for a very long time. Technique/topic based approach so there are a lot of concepts here that can be applied in a wide range of applications.
Circuit Bending - Reed Ghazala: http://zhagun.ru/Circuit_Bending_Build_Your_Own_Alien_Instruments.pdf
Reed Ghazala invented circuit bending and wrote a book about it. Great in depth run down of techniques to circuit bend audio electronics to make weird noises. Some schematics but mostly general principles.
CMOS COOKBOOK: http://chiclassiccomp.org/docs/content/books/Electronics/CMOS%20Cookbook%20-%20SAMS%20-%201994.pdf
A little more on the technical side. This book gives a bunch of schematics for how to achieve certain functions with CMOS Logic Chips that can be applied in synthesis/audio processing/generation (most synths Ive built have been based around this type of chip) Need some basic understanding of circuit design. Mostly useful as a reference.
Electronic Projects for Musicians - Craig Anderson: https://msu.edu/~dougl126/Electronic%20Projects%20for%20Musicians.pdf
Some good projects for pedals/audio processing. Pretty easy to follow and schematics are provided. Has a range of projects from beginner to advanced.
Hackaday Logic Noise Series: https://hackaday.com/tag/logic-noise/
This has been indispensable. Step by step, module by module, the author builds a modular synth system from scratch from cheap components. Topics covered include oscillators, sequencers, filters, drum synthesis, and a bunch of other weird stuff. This one can also keep you busy for a very long time if you let it. Assumes basically zero electronics knowledge. and there is a video series companion.
Doepfer A-100 DIY Page: http://www.doepfer.de/DIY/a100_diy.htm
Super useful reference on how to build simple parts of a larger synth system by Doepfer. Also has some electronics fundamentals written in.
LUNETTA DOCUMENT by droffset: https://docs.google.com/Doc?docid=0AZIwOP-PR9sSZDlidzgzbV8wY3RjenJqanY&hl=en
Nice intro to Lunetta Synthesis (building synths using cheap CMOS Logic ICs). Nice parts lists/project ideas.
Fun with Sea Moss: http://milkcrate.com.au/_other/sea-moss/#digitallogic
Nice little easy read on some fun easy CMOS circuits.
Lunetta Link-O-Rama: http://electro-music.com/forum/topic-42772.html
Just a ton of links on synth construction.
Experementalists Anonymous DIY Archive: http://www.experimentalistsanonymous.com/diy/index.php
SOOOOOOOOO MANY SCHEMATICS on everything you could possibly ever want to build; many are like way way way way above my head, but theres some good stuff in there.
I tend to use this a lot.
Music Thing Modular Reading List: https://musicthing.co.uk/pages/booklist.html
Many readings on this topic
Look Mum no Computer: https://www.youtube.com/channel/UCafxR2HWJRmMfSdyZXvZMTw
This guy is a real cheese ball but he's inarguably a DIY synth wunderkind and pretty entertaining at times. Also hes made some videos about really great easy useful circuits; passive filters, sequencers, drum stuff, etc etc. also check out the synth bikes.
Simon the Magpie: https://www.youtube.com/user/sliskpotta
Also a cheeseball but has some good instructional vids on circuitbending in there.
Great Scott: https://www.youtube.com/user/greatscottlab
Not explicitly sound/musical but this guy is my go to if I need a crash course in some specifici electronic topic. like if I need to know what an inductor is, ill go here and he usually has a video. Kindof just like his accent.
