Honestly more impressive to me that they were able to figure out how to cram 3 usb connectors and accompanying breakout boards into a product just to get the 5v from the first one.

At least we don't see 2 full length USB cables like some other projects. :P

Actually nvm looks like the original PCB isn’t even still there 😂

u/The-Devil-Itself 2d ago

Actually , there was no pcb in it , it was just a detached cable mic for some kind of magnetofon

What does works with basically everything mean? Can it start my car?

Possibly a PA system or tape recorder.

Dynamic made CB radios with microphones (or just placed their name on it?) It looks like some of those I used in the 80-90's but I'm not seeing a (push to talk) button so this 🤷

Why does it have 3 usb connectors

8

u/The-Devil-Itself 3d ago

Because i didn't want to desolder the usb c connector from the sound chip, it was way less troublesome

Flux will over time breaks down into salts which are conductive. Just a heads-up

u/peeriemcleary 2d ago

In the old days this was a thing and mostly occurred with long or repeated exposure to high humidity. Modern electronics solder flux is very stable and doesn't contain added acids. That's why they call it "No clean". However if it's a non descript chinesium solder, it may not be meant for normal electronics but for a specialised purpose (like soldering stainless steel or aluminium) and have aggressive flux additives.

Yeah I use good quality no clean flux but this looks a bit fishy.

u/peeriemcleary 1d ago

True. It's quite brown and there's a lot of it

u/The-Devil-Itself 1d ago

It's actually solder resin

Kinda looks 1950s but could been wiser to have a xlr out for range and noise also you could also shield it to avoid rf leaking in the sound

u/The-Devil-Itself 2d ago

I'm gonna put a preamp in it, and some shielding too , i just wanted to finish the basic stuff i wanted to make , this project has been in the drawer for 2 years, with many other

u/avrguy004 1d ago

I have some ssl4000g preamp card schematic if needed avaiable just it runs on +-18v and +-17v and up to 66db gain according to the schematic

u/saltyboi6704 3d ago

It's a shame you weren't able to line up the port with the grommet...

Please make the on off switch actually work
