Did you know you can make a radio that transmits from stuff sitting in your car, home and junk?

Here is a photo of one of the oldest radio diagrams

Just think cars batteries, The coil from a car, some bare wire wrapped around a set of chair legs, couple of bottles. This is making it super simple

Shit so easy a boy scout could build one

I built a radio out of a kit I bought from Radio Shack. I mounted it inside a little cabinet. I think I still have it around here. I mounted a telegraph key on top of the cabinet and used the radio oscillator to make a tone. I used this to practice morse code.

I had the same kit, I used that to teach me Morse Code

I built a AM crystal radio just from household items and some wire and earphone to hear it

That is neat. But out of all that stuff. I only have batteries in my place

It won’t be long before we will need to know how to do that again ‼️

Hint, buy double edge razor blades, some paper clips, and a some pencils

you be able to hear radio frequency, but you won't be able to transmit. But you would be able to hear them coming

[humanearth]

needs no batteries

here is a newer version of the same thing

You should start manufacturing these then sell…pitch Musk at Twitter 😂. I’m sure this will be a big hit and install into Auto where phone holder and car brain are…

LOL! Some of us were NEVER boy scouts!

I recently downloaded an MIT pdf about how to make a synthetic aperture radar for about $200.

Awesome

Make a deathray instead and I'll be impressed.
