This is a Dengist community in favor of Bashar al-Assad with no information that can lead to the arrest of Hillary Clinton, our fellow liberal and queen. This community is not ironic. We are Marxists-Leninists.

This community is for posts about Marxism and geopolitics (including shitposts to some extent). Serious posts can be posted here or in /c/GenZhou. Reactionary or ultra-leftist cringe posts belong in /c/shitreactionariessay or /c/shitultrassay respectively.

We have a Matrix homeserver and a Matrix space. See this thread for more information. If you believe the server may be down, check the status on status.elara.ws.

You can build your own AM radio in less then an hour with a large metallic object (car, bike, large piece of scrap metal, basketball pole), some aluminum foil, a small piece of copper, a battery, and any sort of speaker.

It’s a pretty common childhood science experiment where I am to build functional jerryrigged radio.

But you are right, building functional AM radios was and is pretty common for how cheap the components are. Plus I’m pretty sure I can still go to a store and buy a small working radio for less then 20 bucks.
