I was surprised by that, too. When I went looking for a way to decode them with RTL-SDR, I assumed it wouldn’t be parsing the audio but a narrowband data stream. TIL also.

I don’t want to repeat what others have already said as that’s all pretty accurate. As a rule of thumb, just look at the site sidebar for various instances and just avoid any that base themselves around any form of identity politics. Sadly, that’s a lot of them, but life is better without those kinds of attitudes in your face all the time.

I don’t have an EV yet, but I already refuse (prefuse? pre-refuse?) to use an app to charge my car which pretty much locks me out of most fast chargers.

I’ve been WFH since COVID and only drive a few times a week. When I do get an EV hopefully in the next 1-3 years, it’s probably going to basically trickle-charge from a modest PV setup. If it takes 3 days to fully charge, so be it; it’d just be sitting there anyway. Though I’ll probably wire in a 220v level 2 charger (or whatever they’re classified as) on the rare occasion I need a faster charge.

True, but I’ve had two grid-tie inverters, and both have had anti islanding protection and would not function when there is no utility power. Pretty much all grie-tie inverters have that protection.

I’m specifically referring to the interconnect agreement, though, which is where you have to jump through a bunch of hoops, fill out a bunch of forms, pay a fee, wait for the power company to come and inspect it, and get the utility provider’s blessing before you can hook in a grie-tie inverter and export even a fraction of a watt.

And you have to go through that process every time there’s a change to your system. e.g. If I start out with a 400 watt balcony solar kit, get that approved, and want to add another 400w kit, I would have to file new paperwork, pay another fee, wait for inspection, etc.

I’m all for reasonable safety measures, but the power company in my area is clearly doing all it can to pay lip service to “yes, we support balcony solar” while also making it as painful as possible for homeowners to actually implement it.

I’ve had to plan on a PV+battery+load sharing solution because my utility provider will fine the absolute crap out of you if you export any power without an interconnect agreement in place. I used to be able to stealth grid-tie with the old analog meters (I never produced more in a month than I used), but these new digital tattle-tale meters will rat you out instantly.

Metalworking. It’s not so much beyond my ability so much as it’s out of my price range to get into it. I just don’t have any of the necessary tools nor an appropriate workspace, and I’d basically have to build a workshop and start from the literal ground up.

The irony there is that there’s a link between microplastics and Parkinson’s.
