I’ve been dreaming of building my own electronics since I was a kid. I spent so many afternoons at Radio Shack, and even tried my hand at the occasional kit, with limited success. Every few years in adulthood, I’ve given it another try, observing a steady downward trend in difficulty.

I’m telling you: we’re at a special moment here. The labor savings of open source, the composability, the fun: all of it has come to hardware. You can build things that solve real problems for yourself. I first imagined my heat pump devices over a year ago, and I have been frustrated they didn’t exist every day since.

Now my dreams are real, and the largest energy consumer in the house can be automated and remotely controlled.

That’s amazing.

As soon as I gain employment again, the very first thing I’m buying is a 3D printer, and I’m gonna start building stuff.

I don’t quite know what yet.

But I’ll find something.
