Currently it’s buying stupid but vaguely useful things.

I spent $50 on a SDR radio that can listen to a very wide spectrum of stuff. Also got a cheap pair of GMRS radios and got hooked onto the local repeater tower for about a 50 mile radius of communication.

A friend had a gas coming from their oven on occasion so I got a sensor for about $70 to try to fix it (and did so successfully)

I have more flashlights than any one man needs, but they do come in useful.

I just got a lock pick set and a practice lock. Probably never use any vague skill I’d develop, but if it saves me calling one locksmith, one time, it’ll have paid for itself.

A good pair of binoculars is just nice to have.

Tools of any sort.

Non-stupid prepper stuff should some crazy shit go down. Water purification, solar systems, weapons.

I’d like to try one of the mesh networks, but have more pressing hobby-crap to pursue.
