Good LORD man! Speak English!Raspberry Pi. It's a little computer the size of a deck of cards. Runs on 5 volts from a USB port. You can run Linux on it, so it doesn't need a lot of memory or a big processor. You can do about anything with them, like set up a web/network server in your truck to connect a bunch of wireless cameras mounted all around the truck. Set an old tablet to automatically connect to that network when it's available, and put a web page on the web server that displays all of the cameras. $49. Well, and hours of fiddling. Dash mount for the tablet, another about $50. I'm thinking about a magnetic mount camera that I can stick on any trailer I might be towing. If it won't reach the Raspberry Pi from back there, for another $49 I can make another one into a signal booster.
Or with a little extra hardware, you could make one into a custom weather station for the house.
Or a file server to stream all of your movies from.
Or a VPN server.
Or a TV that mirrors what's on the main TV, but in the bathroom, that comes on automatically when you enter and doesn't turn back off while you sit on the pot.
Or a Digital Sound Processor that doesn't use expensive proprietary software.
Or all kinds of robot stuff.
Basically anything you can do with Linux, which is as ridiculously broad as it sounds. It has several USB ports and HDMI. You can literally plug a mouse, keyboard and monitor in it and you have a little Linux computer. Or not plug anything in and remotely connect to it over your Wi-Fi instead. Plus you can add a hardware controller board to remotely or automatically control all kinds of hardware.
I've got three of them laying around halfway configured for various projects right now.![]()
And then there are Arduino controllers, which I haven't even started with yet...
Good thing I'm old enough that I just don't care if I'm an idiot to such things.
