Howdy! I am not going to deliver a bunch of home page BS, this site is where i track some of the stuff I am working on, if it's useful to you as well, well, there you go. ABOUT THE CIRCUITS: Unless noted, audio circuits require +/- 15V DC and output something like -5 to 5V P/P. The legal disclaimer crap that my brother says I need to say here This site assumes you are a competitent tech and are cautious when working on electronics; seriously, the tube amp data here is extremely dangerous and should not be screwed around with unless you really know what you are doing. ABOUT THE MUSIC Everything you hear was recorded/arranged/performed by me due to my antisocial nature. I am old school, and use minimal computer fixes, autotuning, quantizing, and other egregious digital recording tricks.
About the gear pages:
The schematics, board layouts, designs etc. are my own unless otherwise noted. I try to give credit where it's due; please do the same if you use some of my creations in what you post and/or sell. Some of the PCBs here are untested, I try to note that as well as we go. For untested PCBs, you may have to kludge things to get them to work (I have to...).
For anyone building what's here I'm glad to answer questions (see contact tab, or better, send me a PM via the "cslammy" user on the electro music forum) and I'll try to help. I will assume you have basic tools (cutters, soldering iron) gear (scope, DVM, audio function generator, bench power) and some knowlege of audio electronics. If this is your first attempt at building audio things, you probably shouldn't start here--my "gear" pages assume you have a decent working knowledge of DIY audio already. You'll be better off buying things from say MFOS or Modular Addict where you can get real kits, which these aren't. That said if you find a board interesting contact me, I may have some spares and will be willing to swap for whatever you're working on; I also need help testing PCBs from time to time. Thanks.
Added an Arduino Section to the Gear pages. An analog mind in a digital world?
To track things I'm working on vs. finished stuff here, I started an Audio DIY blog.
Added a non-inverting mini op amp PCB to my growing list of gain circuits.
Added +/-10V Precision Voltage Reference
Updated and augmented the op amp gain page.
Vactrol VCF Rev3 New PCB layout and wiring diagram--tests working.
Clapton covers, Finally--some more MP3s. I play all the parts. Happy birthday Super D!
Dual LFO, op amp based, using TLO84's. Tests working.
Tests working!! Korg Ringmod, a simple design that sounds a lot better than I thought it would. i have fabbed a board, stuffed it, wired it, put it into my old modular, and it worked first time!
I scanned my old documentation to PDF from my 2002 ASM-1 VCO build. Working on laying out the board again with some improvements but after 15 years the 3 boards I built with custom PCB's still work great!
