I have no experience whatsoever with heat pumps. I think they do some black magic with reversing the refrigerant flow; so there is probably a whole other set of specs and procedures for those.

Not a professional but Ive DIYed it. So the following may be oversimplified and/or not best practice.

You’ll need a gauge set so you can watch both the high and low side pressures. Your unit probably does not have ports to attach the gauges but they make some adapters that bolt on and pierce the lines. These work ok but will probably be another spot for leaks down the road.

You’ll need to figure out what refrigerant your unit has in it, there’s usually a metal placard somewhere that tells you this. This is how you’ll look up where your pressures need to be.

Finally you’ll need to source said refrigerant, which you likely cannot buy without a license or bribing someone.

The actual charging procedure I would look around on youtube for. It may vary depending on your type of unit but it’s usually pretty straightforward.

WTF are all these “Refresh of version…” updates? Am I unfresh? Do I need to bathe? (probably)

Edit: It’s like it saw my post from yesterday and said “oh you like that do you?”

It’ll eventually wear off your skin. In a few days. On other, relatively non porous surfaces, it can be removed easily once cured. Porous surfaces like wood, cloth, or carpet? Sorry, it’s here to stay.

The biggest hurdle I’ve ran into is that GPS resolution just isn’t accurate enough. If you want something that can follow a planned route without having to rely on a bunch of obstacle avoidance (which is difficult enough in itself) then you’ll have to set up some sort of local RTK in conjunction with the GPS.

Currently I’m just setting my mower up like a FPV drone that I can drive around remotely from the comfort of air conditioning. Hoping someone comes out with a good automated solution.

Same here. Red Hat 5 from the Linux for Dummies book.

A lot of the 3d printed designs are.
