Really? Did they not have this in Practical Electronics also? I'm "gob-smacked" as they say. In fact, I'm just about to send an email to the original publisher of Practical Electronics asking him about this.
I'm not saying you aren't right, you understand -- and I did read Practical Wireless also .. .but I would have sworn this was in Practical Electronics -- watch this space...
great article but "Take 20" was a constructional feature of Practical Wireless, usually authored by Julian Anderson and, in later issues, David Andrews.
I'm sending you a couple of issues from the 1970s so you can indulge in our favourite passtime - electronics nostalgia :o)
The UK used to be covered in shops like this which fascinated boys like me and their fathers! Sadly, most are gone. Cambridge only has one left (apologies for the stupidly long link):
In reply to David, I too have a mountain of junk to strip for parts, here in England. Trouble is the space it takes up and the time to strip the good stuff out of the rubbish.
All I can say is lucky "Mock's" is on another continent as I'd be sure to end up with even more of a space problem.
On the subject of low component count's, I'm still impressed by "Lionel" train's "super sound of steam" gadget from the early 70's. Produces a lovely "chuff chuff" sound with only 20 or so components. Very clever.
Possibly as a result of those days I began assembling a store (read: glorified junk box, though it is pretty well organised) of electronic bits, so I don't have to order or visit a store to get components. It works 90% of the time, but boy do I have a lot of stuff. When I left Zimbabwe I got rid of a fair bit, but here in Aussie they throw away anything and everything, so I grab it and strip it and have all sorts of stuff that I can see a use for. Drives my wife nuts, but most of the time I can get down and build things whenever I feel like it. Does anyone else do this? I think I should start selling on E-bay....
We are fortunate to have Tanner Electronics here in the DFW Metroplex. It reminds me of your "Mock Electronics" store very much. If you're every in town, check it out.
