Bread-board circuit construction any one?

Bread-board circuit construction any one?

Post by daveB » 10 Dec 2018 15:30

I was amused - a whole new meaning to using a bread board for circuit construction. [Note for the young - in the early days of wireless circuits were literally built onto a wooden board with all the components screwed down to the board and joined by wires. Hence "bread board" as the kitchen was the obvious source of a nice size board :) ).

I am not sure for bread-board construction techniques but i remember in my early teenage years being given a tandy 150 in 1 kit which connected the composants & wires using small springs. I remember well enjoying many hours building electonique projects with the kit and my favorate was a crystal radio, were such project boards available back then early 70's to the Saxon Cousins?

Happy Memories & good times

Yes - they were available. I don't think the one I had was from Tandy back in the 70's.

As a child, I used to have had a couple of Philips 'Electronic Engineer' kits. I remember building walkie talkies and yes, a crystal set! I can't remember the years. Maybe I was 10 or 11.

Back in the day early 70's i remember an article in a french hobbyist magazine explaining how for building a radio using limited composants & crystal au galène. I remember building the project with no succes so replaced the crystal au galène with a diode au germanium and received results. Also i have experiment build variable capacitors using cardboard & aluminium paper but of course not accurate pf comparison to manufactured types.

Happy times then for being a teenager

The Ladybird Book - Making a Transistor Radio was my introduction to construction back in 1976. No soldering involved, just trapping wires and components under brass screws on a small wooden base, but it worked and taught the 10 year old me a lot!

I've just found a five minute youtube video which shows this book page by page.

https://www.youtube.com/watch?v=t4h2GmlgpxQ

Enjoy!

Even better - it is here in pdf format:

https://www.americanradiohistory.com/Ar ... s-1972.pdf

This is a great web-site with loads of radio mags going back to the earliest days of radio - fascinating if you like history. e.g. earliest mention of building a super-het. When was the first article for building an ssb transmitter published in the amateur press?

I've come across a "construction" article for a superhet receiver in the Oct 1923 issue of "Experimental Wireless" https://www.americanradiohistory.com/Ar ... 923-10.pdf

There is also an article offering an explanation for the fading of signals and enhanced night-time reception of short-wave signals - below 600 m (500 kHz) i.e. medium wave and higher.

Plus reference elsewhere to the inability to get decent reception due to 'hash' until a certain radio transmitter goes off-air.

And in the Nov 1923 issue -an article on"side-band" telephony.
