I've been servicing recording studios here in honolulu, since the late '80s. Also concert sound, video projection, and theatrical lighting systems. I play electric rock-blues guitar and know what guitar players want from their Marshall amps. And I do recording engineering and production, so I know what recording engineers need from their monitor amps and speakers.
I have several projects I'm currently working on. And several ideas I want to develop ito new projects. I was thinking about some of those when I came across this site. It seems so serendipitous, I just had to join and write something.
I've spent the last week or so working on PC board layouts of several voltage regulator designs I've built and used over the years. I built a replacement for a recording console power supply regulator, that has been working now for near 10 years. I couldn't find the high current regulators that the original design used, so I used a pair of 723 ICs and external pass transistors and made my own substitute. The 723 has been bery bery goot to me! I used another pair of them to make a bench supply that adjusts from 12V to 35V plus and minus are individually adjustable and the pass devices have a 20A rating. I use this to experiment with various discrete op amp designs. A modern version of the Jensen 990 is my goal.
I've also recently built my first switchmode regulator based on TIs TL494 PWM controller IC. My experience with switching regulators is limited. I never had to repair one, only replace the complete unit, so I'm having to learn about them on my own. I've collected a lot of documentation and learned about buck, boost, buck-boost, fly-back etc. But it is all "book learning" as opposed to "hands on" at this point.
I thought these regulators might interest someone. I will post the schematics and artwork here eventually, but I need to find out more about how that is done. If anyone is interested, let me know.
Aloha, RAF
Hi! I'm shocked how cool this wesite is!

editing line drawings
For editing general line drawings, the best editor I've found is "inkscape". Download it for free ( http://inkscape.org/ ).
Some people use inkscape even for sketching schematics. Other people prefer a specialized schematic editor.
Congratulations, you've already posted more images to Open Circuits than I have :-).

writing on wiki
Some of my favorite pages about writing on wiki are:
I'm dropping little snippets of information here, even though I plan to separate them out into another page someday. The "sentence to page" and the "big buckets first" essays should explain why I do this, rather than creating a fresh page now and placing 2 snippets of information into it.

To who ever edited this page earlier. You did no favors to anyone here. You did not contribute anything. You removed information that others spent time and thought composing and sharing with the community. If you did this by accident, you owe it to yourself and everyone else (not only on this wiki, but on every wiki) to learn how to use the tools properly, so you don't damage things.
If you did this knowing what you do, then you are a malicious prankster and should be banned from the site.
I prefer to give you the benefit of the doubt, so in the future, be more careful.
