Re: Multi-Freq Pig Rig

I was thinking about using single pin sockets cut from a female "breakaway" header. I'd just install them in the pcb holes already provided. Here's a link to a source and picture. They're handy for a lot of hack jobs.

Great idea......

The crystals are spaced at .200", but the problem is the "individual crystal" leads are spaced at .200" apart and a dip socket spacing (one side to the other) is .300"

You might use a "wire-wrap" socket which has longer pins and bend them to fin into the .200" spacing thus adapting the crystal lead spacing to .300" allowing crystals piggy-backed (no pun intended) on a dip socket to be used.

Excellent idea about putting all crystals on one dip socket then rotate socket to swap frequencies.

While using a switch is pretty much out, has anyone given thought to adding an IC Socket and mounting the Rocks on a DIP Plug (or header)? Then it should be quick and easy to change frequency. And it they were plugged in backwards, it would not matter. Or go to a 16 pin DIP, with one side for the 7.031 Xtals and the other side for 7122, just reverse the plug to change freq. Just a thought.
