Back in the days of the first transistor radios, and the old valve sets, there was also a little unit that could be built by those that were that way inclined, it was called a crystal set. As kids we used to build these and have fun trying to think of ways to pick up other stations, as they were only good for two close range ones at the time/ am 2BL, 2FC. I would love to build one now and see what happens if anything...lol.
Can't for the life of me remember the circuit, or all the components.
A0 90 Diode
22ohm resistor
680pf capacitor
single gang tuning condenser
3in areial coil about 50 windings on a ajax can
headphones
?????.
Anyone Familiar with these little old time gadgets?
Would love to get a circuit.
Cheers Axle.

At work today we were talking about the exact same thing crystal radios when we were kids
Then it went to trucks with mechanical hand signaling device which you had to juggle with while changing gears and when you let it go it slammed down against the door
And then cars with turn indicators that were a small arm that came out of the door pillar before flashers were around
I must be getting old to remember these things there again my bike did have a big wheel at the front and a tiny one on the back
and my only toys were a piece of wood and a piece of string

Yeah,
well now that brings back some long fogotten memories! & I remember Dad had a Chev truck & the self starter (it had a crank handle as
well) was a sturdy metal button on the floor & the ignition switch was just a toggle switch on the dash. I used to have a vehicle & the headlight dimmer switch was activated with your foot via a floor button.
Dad, he is 93 now, still reckons they stopped making decent cars when they stopped fitting them with crank handles!! Thank God for progress.
You must of came from a wealthy family? I only had the piece of wood, mum used to save the string for wrapping up things. Cheers.

Hi Barry
My dad had a T model Ford, when I was a kid, it was my job to turn the Tail Lights on at the back of the vehicle, a little push pull switch,
and it had no Fuel Guage, you would have a wooden stick, to put
down the filler pipe to see how much petrol was in it.also the doors
had no glass wind up windows, just clip on clears, so when it rained
you would have to stop and put them on.
Cheers
