Technical Hints
These pages are meant as an presentation of the S-DIY i do. They reflect my current and certainly limited technical understanding of these things.

A WORD ABOUT THE PCB LAYOUTS: The layouts i made work for me, they are not perfect though. Sometimes i might have made some mistakes. So if you have some findings don't hesitate to contact me.
The most layouts show footprints for cliff sockets in order to mount these PCBs to the front panels. they are not placed according the 0.8 inch grid, the spacing follows the metric system: 20mm spacing. Consider this before making panels.

A WORD ABOUT BUILDING OTHER PEOPLE CIRCUITS: I think it's a good practice to breadboard any of the circuits i find in the world wide web before i do a PCB or a frontpanel. Nobody is perfect. Everyone makes mistakes. I do, you do and others do.
