And something as simple as a 3D printed box given at a hacking convention can cause a big problem in the military.

So this is... It pretty much is.

It's partially what it is.

It's a HackRF, which is just a... It does a ton of things.

Radio-related only.

Which, you know... Well, not just radio.

I guess also some other bands because it's...

going into a whole radio nerd conversation.

It's from one megahertz to six gigahertz.

And I don't know if you know how big of a range that is, but it's huge.

It's like the only device that I'm aware of that can do anything like that.

But if you look in the receive, you'll see I can look for airplanes, boats.

I can even

Access the intercoms in a CVS and Walgreens and like that thing is pretty wild.

I could, over some of the older loudspeakers at fast food restaurants, I could talk through them and listen to them, you know, in the bars, touch tunes.

Well, yeah.

So it's going to receive or transmit.

So you could either receive everything around you or transmit at a very large range.

And that is pre-programmed with some third-party firmware.

It's called the H4M or the Mayhem firmware.
