I'm happy to now know about perma computing.

up to the level of the mid 90s

So pair this with back-to-basics tech (e.g. text files)... that can serve us extremely well.

Yup. The closer I am to her friends... the stronger the compulsion. It's like magnetism.

As a dad, I have a strong compulsion to tell (bad) dad jokes. Ideally puns. All the time. I didn't used to be this way.

As a rule, the highest-paid workers at Mondragon cooperatives earn only six times more than the lowest-paid workers.

And I bet these salary-capped co-op leaders are still appropriately capable / qualified. The U.S. billionare situation is ugly.

But there is some valid concern around internet-connected PV / battery power electronics getting bricked remotely.

All good, I appreciate what you built! On desktop with Windows 11. I just tried it again and it was much easier to see the info (thru hover) than before.

Thanks, it's much easier to load info with the option you shared.

This is awesome. It'd be even more awesome if it was easier to show a power plant's info upon hover / click. ...It's currently too much of a cat-and-mouse game for me.

I've heard the EV charging has played a big role in the maturation of GaN / SiC.

A distinction was made:

the transfer switch variety switches your house between the inverter and the grid whereas the disconnect just physically disconnects the inverters output

Thanks, and I agree that a DIY-inverter designer should be able to meet grid-interconnection requirements (e.g. IEEE 1547-2018). With that said, I think case-by-base evaluation from the AHJ would be prudent without a UL listing... something that AHJs don't want to do.

I'd prefer to just put the DIY inverter behind a transfer switch (with an adequate battery bank and maybe a small propane generator)... with the grid as emergency fallback.

Why the fearmongering?

The main concern is exporting to a downed grid that line-workers are trying to restore.

Not that this is accepted by insurers or AHJs ("authorities having jurisdiction"), but one can use UL-certified components in an (open-source) _assembly_ that itself isn't UL certified. This at least supports the argument that the overall product is safe if thoughtfully designed and assembled. An example is the OpenEVSE level-2 car charger (which I had a really good experience with).

The creator of OpenClaw, for example, has come to appreciate grammatical / spelling errors in human writing (as he said in a recent Lex Fridman interview).

Loosely related: This Lex Fridman discussion with a nuclear-fusion engineer, about 1-million-amp 100-million-degree electrical systems... blew my mind: https://lexfridman.com/david-kirtley

I really like this guy's drywall-install how-to videos: https://www.youtube.com/@vancouvercarpenter

For me, there's a sharp binary: If I ask AI to "own" a coding-problem solution — with me passing back the failure responses until resolved — my mind gets numb and I learn nothing. If I insist on owning the solution — using AI in my effort to better understand the problem space — my mind is active and I get better at coding. Sometimes I'm lazy and fall into the former. But mostly, so far, the latter.

Thanks for this! ...Thanks for helping me curb my naivete a bit. I think you'd appreciate this effort at even cheaper grid-scale chemical battery storage: https://www.volts.wtf/p/can-second-life-ev-batteries-work

This is just a grift.

I'd like to understand why. Just too much complexity? Gravity storage is compelling to this layman.

I'd love to see an unbiased financial-analysis comparison: this vs. hydro vs. electrochemical.

I think the heavy investor subsidization / speculation makes this different. The high cost of early 1Tb flash drives was largely borne by buyers.

The parent comment's point is that we _should_ care because cheap frontier-model access (that many of us have quickly become hopelessly dependent on) might be temporary.

Right, $200-300/kWh is more the range for ~16kWh residential stationary energy storage systems.

Net metering is gone in most of California (for new solar). I think it's going away in general. Distributed solar supports a more stable grid for everyone (per UL 1741-SB requirements).

You can run sans grid with Enphase (with their "system controller").

Thanks so much! I do plan to open-source it. ...Once it's tightened up. Please email me if you'd like to be on a beta list. mike at bishop dot wtf

tl;dr from the bottom of the blog post:

Type-based grouping is great for tech-focused tasks, consistent naming, and large sweeping changes.

Context/process-based grouping shines for domain clarity, team ownership, debugging, and mapping business problems directly to code.

Your comment made my day, thank you :)

A framework for Excel spreadsheets, written in Excel VBA. A nine-minute demo video is here: https://www.cabin.wtf (the file is 4mb, not 4kb)

If nothing else, this shows that the Excel UX can be radically changed thru one small Excel file... so much of the object model is exposed to VBA.

We park on the other side of a city park from my daughter's school. ...The five minute walk thru the park together is a highlight of my day.
