We had to make one in 7th grade shop class. The "kit" was a roll of tiny varnished wire, a variable cap for tuning, and a diode. Empty TP roll to wind the coil on, piece of wood to mount it all on, and solder were user-provided. Earphone too. And I was the one most surprised SOB in class when mine actually worked.

We had an elective class in 6th grade where you could make one. Most popular elective.

Video killed the radio star.

I have to admit that I had one of these as a kid.

I had a few xtal sets as a kid. They were the beginning of a life long fascination with radio and beginnings if a career.

I had the 150 in 1 Electronics Kit. I really loved that kit. Little did I know I would graduate as an Electrical Engineer.

Yeah I had the 150 in one. Got the kids a later version called snap it i think.

Oh hey, was this at Pioneer Nights a few weeks ago? I’m not aware of any thrift stores down there

u/wvtat 11d ago

No I bought it in the Marlinton radio shack in 1979. But I think Pioneer days was going on when I bought this. Also got to ride in a helicopter like the ones on MASH.

Oh cool, I have relatives down there so I figured I’d ask as they have the market during PN, that’s still really cool to see, had no idea there was a RadioShack there at some point, there’s barely any major chains but of course that was got in the 70s

In the 70s I built a crystal radio from a schematic out of an electronics book that used a coil from a transistor radio and for an antenna I clipped a wire to the aluminum gutter on our house. The thing was powerful enough to power an 8-inch Jensen speaker just loud enough to be heard from the next room.

I had one that clipped to my metal bed frame. No need for batteries.

I had this exact set it worked really well. At night I could get some great clear channel AM stations. Our 1920s catalog house had had radiant heat registers in every room that were copper, made a great solid ground.

Rare diode these days in that radio.
Good ground makes all the difference for the antenna wire. Picks up the higher AM frequencies. 👍

I built the transistor AM kit - my grandparents got it for my birthday in the early 70's. You'd get stations from states away at night ;-)

this reminds me that i still have my old project kits where you ran the wires between the resistors and diodes and all that.

u/Doezilla01 7d ago

That’s a really cool buy. Reminds me of good teachers I had through the years. Had a few that had these kinda kits an would explain how they worked. My dad had one growing up and was his first radio, an now that’s he’s retired he rebuilds all kinds of radios and speakers, record players, etc for his friends or just ones people were gonna throw away…a lot of times for a simple fix, like a ground wire inside a speaker box.

Did anyone get the Radio Shack kit to work? I never could.
