International Crystal made several different little modules.  Crystal oscillators, mixers, amplifiers.


 


I'd need to look through some old QST archives to find their offerings.

Hi all,
The question.

In the old, and Im talking 60's or 70's ham magazines there was a vendor that sold little modules that could be hooked up to product various items.
Individually not too complex but string enough of them together and you can make basic projects out of them.

Any idea of what they are called? Product names, vendors, data along that line.
Schematics of the various modules?

Given all the neat modules on places like Amazon, was wondering if this could be a product again.

One of my x bosses made a converter module that took an ordinary vehicle AM/FM and turned it into a multi mode AM stereo receiver with pilot detection.

Been working on some projects.

This is my second batch of Type 538 camera batteries as a work in progress.

Been playing with an idea of making a power bank for a laptop I have here. 
It would use hot swapable power tool batteries.
So far the prototype has been kinda neat.

Share a thought as time permits.
Thanks in advance.
Mike
