Making quick prototyping modules

Here’s an older-ish how-to on making quick prototyping modules, Jeff writes – “For years I have had a need to quickly create electronic circuitry for experimentation. Like most other people I have gone through all the stages. Wire-wrap, soldering point-to-point, pluggable ProtoBoards. I have tried various methods for making my PC boards. Iron-on transfer, plotting directly on PC boards, tape on boards and various forms of photo etch. Even when I had good results I still had a single purpose board. Sometimes you can modify the board for another purpose, but there had to be a better way. I had been contemplating creating modules with the old methods. Probably point-to-point wiring on perf board. But after seeing that people were having good luck with PC boards from places like www.apcircuits.com and www.olimex.com I decided to go directly to PC boards…” – Link (schematics included).
