Good morning, great viewer Mail! ❤
Living in the UK these booklets were attached to the front of the magazines during the 70's
i kept mine in a small box which must have been lost in one of my house moves.
The information was basic but there was no RUclips or other ways to learn the basics.
These magazines were our only way of learning until i went to Tech School.
A great reminder of my early days.
Wow !! That takes me back to my early teens, i still have that very book amoungst my various electronic magazines in the garage. I think it was from Elektor magazine, possibly.
Many thanks Fran

Oh so many years ago, I did make a circuit board etched with Ferric Chloride. It actually worked, but I never did another !
I made one or two, back in the early 80's.
That Ferric Chloride was nasty stuff, it burnt trough anything metal and stained clothes
but if you wanted to make a PCB there was nothing else.
me too. didn't even have a proper pen. just used a permanent marker. and yes, i recall the circuit worked. i think it was a small audio power amp in which the output transistors got quite hot - had to manually adjust the quiescent current (BD139/140 pair) - circa 1975. another construction method i also used for RF projects was to use an unetched fibreglass pcb as a flat plane and file or scrape the copper back to make rectangular pads.
This all sounds as i remember that time,most of the projects we could't afford the parts for if you could find them, i often took old projects apart just for the components, i wasn't until the 80's that components became more easily available and the likes of RS Components still made you open an account. Happy days that learned us some very useful skills.

In the 70's I used the Radio Shack "Sharpie", and made about a half dozen ferric chloride etched boards, over a couple of years. Always in the garage, as it got messy.
I've only just STARTED and I HAVE to say that I am LOVING your new 'radio jingle' intros!
G.P.O - the General Post Office - responsible for the Royal Mail and the telephone system. P.O. relays were the standard telephone relays often available in the surplus shops when they still existed.
These or similar relay were used in step-by-step and crossbar in Australia. They had a long exposed coil (with a tape or mylar over them), and contacts on the top. Tools could adjust armature and the long reeds. Line relays with windings from battery (-50 or -48 volts depending on the naming system) and earth fed power into the line, and when the handset was picked up it "looped" the line, causing the relay to pull in, allowing activation of dialling out or call answering processes.
In the 70s someone gave me a set of six guitar pickup magnets. I made a bobbin of wood to mount them and unwound a 2000-type relay to get the wire for the pickup coil on the bobbin. I knew little of pickups and didn't use enough turns. It was only 0.5 ohms. I didn't even have a guitar amp, and it was only audible using the magnetic pickup input on my stereo. It does fine into my current Fender valve guitar amp though.
I remember that booklet - brought back some memories! Glad to see the old OA81 diode and the ‘use-everywhere’ BC109…… The other common transistor in use was the OC71 - where you could scrape the paint off the top of the cylindrical body and use it as a photosensor!
Beautiful Tomorrow , I go to local swap meet and love finding stuff, I love old books , electronics Thank you. Frank Martinez Downey California ❤❤❤
Love this kind of stuff. I can FEEL that paper when you described it. So satisfying that super thin paper
I love "Viewer Mail". I was lucky enough to be on your #7 version so I feel like I'm a tiny part of your life. Never forget, Fran, that you are loved.
Well it eventually made it -- at last.. greetings from Ireland
Again, great presentation. My dad had two miniature booklets for his pocket. Everything from electronics info, formulas, wire gauge, plumbing info, almost every bit of handy info a DIY'r to engineer would need and use on a daily basis. It was put out by General Electric in abt 1970. Thanks for the memories,
Oh, I had that. I used to get that magazine before progressing to its bigger brother, Practical Electronics.
Those pocket Electronics booklets are great and should be available today. Lots of goodies in there & common sense writing. Interesting stuff. Especially if you have old electronics (tubes),of which I do & they kick ass. Using them as my home sound theatre system. Thanks Fran & Paul.
Everday Electronics magazine in the UK gave away all sorts of things. I still use a component lead bending tool and BA hole and tapping guide! A stabilised power supply for ttl work I made from their circuit in 1974 is still in use too.
Ooh, I remember that booklet! The illustrations look so familiar to me, they could be from yesterday. The early 70s was when I started buying Everyday Electronics magazine at a little newsagents shop at the top of Kirklee Road, Glasgow on the mile walk from home to school - so it could well have been from this very issue. If I remember right Everyday Electronics was the wee brother of other mags like Practical Electronics in that it catered more for enthusiasts newly embarking on their electronics journeys. The projects were a bit less ambitious, and its didactic material was at a more elementary level - as the booklet shows.
This really brings back memories.
Very cool. Thanks so much for the walk-through!
Thanks Fran. Really beautifully described :)
That all seems very familiar and yet very distant at the same time. Thanks Fran.
thanks for the stroll down memory lane Frannie, I still have my old Radio Shack component color decoder with the 3 color-wheels. Resistor/Capacitor on one side & Inductor on the flip-side
I was 10 years old and my dad bought me a subscription to Everyday Electronics for my birthday. We had every issue from the first in 1971 until about 1978.
The projects were usually a bit too basic to be useful.
Those magazines and that booklet were binned when we cleared out my dad's house many years later.
Still got my constructors companion. Came on cover of my Everyday Electronics magazine in 1972. I was 14 and info was difficult to find. Great nostalgia looking back.
An uncle-in-law passed along his collection of Radio Shack's _Engineer's Mini-Notebooks_ by Forrest M. Mims III, sometime in the 90s. They are all early-80s issue, ~1981-1983 IIRC. Some of the part numbers Mr. Mims used are obsolescent (or downright obsolete/unobtanium), but the general concepts presented make them handy reminders. I still keep them at my desk.
I remember reading "Everyday Electronics" magazine. My Mum thought the title was funny, because electronics clearly was not an everyday thing!
Fast forward to the 2020s and electronics are an every-MINUTE thing!
Everyday Electronics projects were usually a bit simple. Practical Electronics was one step up in terms of cool projects.
I think some of those little manuals had a plastic sleeve to carry them in. Lug strips and perfboard were basics in the '70s....
LOL! I've said this before.......this 'unicorn' channel is _definitely_ worth the price of admission!! 👍❤
I think Dick Smith in Australia sold them as Tag Strip, as Jaycar does. Their Terminal Board has tags on both sides, mounted via a screw through the insulator, not via a leg. Altronics calls these Terminal Tag Strip.
Way cool! A shout out to our friends in Ireland! I need to visit Ireland, with a last name of "Flanagan", ya think? Thanks Fran.

Nice little booklet... and all captions in lovely Gill Sans Bold! Monotype series 275, complimenting the regular variant of 262. My favorite typeface ever since I started with the Monotype technology, despite its problematic creator.
Being a tube amp maker myself, I always wrap one wire around the other before soldering - this has been the Keritech way since 2000s. And I love stripboards / tagboards; sometimes I made my own, a trick learned from Black Dog Amplification.
Dare I ask about the "problematic" creator of Monotype?
@@goodun2974 not Monotype, but Gill Sans. Eric Gill, turned out to be a child molester who abused his daughters.
Tagboards like the one showed in figure 5 at 6:20 were often used in old Vox guitar amps, and although I haven't worked on one of those myself, people who do despise the tag boards because they are a little bit too narrow and the crimping of the terminals to the phenolic board is a bit weak, so the terminals have a tendency to work loose when you unsolder and replace old parts. Turret boards or eyelet boards for the win! PS, don't overlap component leads before soldering; a 3/4 wrap with the cut end protruding slightly, where you can easily grab the end of the lead and bend it straight for removing components from a terminal during servicing, is greatly preferred.
@@goodun2974 Google "Eric Gill" - a talented artist but a sexual abuser. :-(
A lot of these were freebies used as promotional. You'd order them with your company's contact info on the back to give out in lieu of a business card. I have some from Cascade Machinery (here in Seattle) that fit in my Fluke case and have everything you need. I went by to see if I could buy some and they gave me a box of them because they no longer gave them out.
Very cool
l still have the original editions of all my Everyday Electronics including that booklet and many others they gave away...great little magazine sadly no longer published here in the UK
'Tropical fish' capacitors
There's actually a company and website titled "tropical fish vintage" which mostly specializes in repairing Organ amplifiers but also has some really good tutorials on guitar amp repair and circuit theory.
FWIW: I have two or three Aviation-related _reference books,_ somewhat similar to this one.
They reference materials, hardware/fasteners, basic systems, etc.
The oldest was printed around 1980 when I purchased it, although the original version of it was first published years earlier. The others I have are from the latter 1980s or 1990s.
Great video, Fran...👍
how about a Radio Shack pocket dial calculator? Got one of those lying around?
This reminds me of the Mini Engineering Books that Forest Mimms used to write. BTW, Ive got a small binder that has many of the data sheets and project ideas for many of the component packs that Radio Shack sold back in the 70s and 80s :)
cool cool cool
Good old tropical fish, some still think they sound better
Do you spell solder different in the states?
Apparently they spell it SAWWDA
I made lots of circuit boards using Ferric Chloride , once you got the knack, timing and temperature right had a lot of success. And when the copper was nice and clean took SOLDER really well.😏👍🇬🇧
Sorry but there's no such material as SODDER or however you pronounce it. It's SOLDER - Break 'solder' down into sounds: [SOL] + [DUH] .😠🇬🇧
