Hi all,<br>
The question.<br>
<br>
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.<br>
Individually not too complex but string enough of them together and you can make basic projects out of them.<br>
<br>
Any idea of what they are called? Product names, vendors, data along that line.<br>
Schematics of the various modules?<br>
<br>
Given all the neat modules on places like Amazon, was wondering if this could be a product again.<br>
<br>
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.<br>
<br>
Been working on some projects.<br>
<br>
This is my second batch of Type 538 camera batteries as a work in progress.<br>

<br>
Been playing with an idea of making a power bank for a laptop I have here. <br>
It would use hot swapable power tool batteries.<br>
So far the prototype has been kinda neat.<br>
<br>
Share a thought as time permits.<br>
Thanks in advance.<br>
Mike<br>
