Bit rot in micro controllers? (2023 Update)

Nah, under a gallon per hour while running the furnace, fridges, freezer, and computers. It runs toasters and microwaves fine, but tends to trip if people forget and use the garbage disposal. ;)h

I bought a 1700W/2000W

Depends a lot on the load. Our outages tend to be in the winter.

Letting it run dry is usually enough.

Cheers

I went to college in Rochester, New York, in an area which was lightly-reclaimed marshland. The college campus was relatively new, and all of the cables were buried.

We could usually count on a substantial power outage in the dorms every year, when snow-melt season arrived and there was lots of standing water around. The annex holding the college computer center had the same problem (it was even closer to the water table).

I don't recall the outages being more than a half-day or so - maybe there were secondary cables to which they could switch, while they fired up the trenching machines and dug up and replaced the shorted sections.

Before you blame the processor, check for dirt accumulated on the button contacts, If the chip was wrong it likely would not work at all. Cooking and stuff like that causes all sort of vapors to solidify on mechanical contact. Simply wire a switch to test if that works? Check soldering, electrolytic caps, power supply voltage..

Why do you need to burn out a stump for cooking?

^^^^^^^^^^^^^^

Well, this was about a gas grill and there ain't never going to be no gas grill in this here yard :-)

PG&E said they'll shut us off early January for repairs. Hopefully that will make things more reliable. Electricity felt like a huge step back after moving from Europe to California. It's so unreliable here.

I have a UPS for the wood stove fans. That will only run them for

30-40mins (with a new SLA battery). I could probably roach on a big LiFePO4 battery but that would now cost north of $200 and require some hack to reduce the charge-end voltage. Main thing, it's long enough right now until I've got the generator set up, cables run and started.

When my dad from Germany was here he said "A lot of stuff in America looks so kludged and temporary" :-)

I need to burn out *stumps* for trees that I fell. It would be defeatist to hire a stump grinder to sort out that last bit of the tree I've felled! :>

Digging them up is considerably more time consuming and requires a shitload more effort! The last such effort took me several months and netted a half *ton* stump (more than two cubic yards of wood) -- removing 7T of soil to fully expose the root structure beneath.

[A neighbor claims my effort ended up in the local newspaper?]

It's about sources of energy. Cooking being one potential use.

Our "supply" is reliable. It's the distribution network on our

*street* that is showing signs of age. Likely related to folks updating services without the buried lines being "rejuvenated" to adapt to same.

When I lived in the midwest (overhead lines), it was a monthly event to find yourself in the dark! Though I suspect outages are

*very* "localized", there, as here.

I can run the fridge, furnace, freezer and stovetop with the genset. Plus most of the "electronics" when their UPSs lose capacity. I've a UPS in the garage that can act in place of the genset (5KW, 5KWHr capacity) save for the inconvenience of running wires.

But, we rarely have outages in the (two month?) heating season so the furnace rarely is a motivating factor to start the genset. And, keep the fridge closed and it will maintain its contents for a while. Ditto with the freezer. For a meal/snack, we can live without the cooktop for a few hours.

The ACBrrrr is the biggest motivation for supplemental power. And, it draws considerably more than the genset can supply. As outages are rare enough, the idea of buying a *larger* genset is foolish. Spend the money for a hotel room if the power is going to be out overnight!

Someday, I'll buy a small "room-sized" unit for those events. But, then, what to use it for when power is available??

There are advantages to overhead utilities. But, they are eyesores. I suppose there are risks associated with pad-mounted transformers (drivers crashing into them?) but haven't seen that as a common cause for "loss".

Your father would be far more amused at life south of the border (or in many {C,S}American countries). Folks with "summer properties" in Baja contend with water being *delivered* to the rooftop tank. The idea of NOT being able to luxuriate in a warm shower is terrifying to me! :< "Sponge baths" make vacationing, there, really distressing...

Get a dual fuel carb, run the generator on propane/NG, no deterioration, burns cleaner, albeit with slightly less power. Store a couple of 40lbl propane tanks and you are good to go. If you run out of propane, switch to gasoline in a pinch. Yes, you can do all the monthly startup and checks but not necessary if a propane fuel is used - still a good idea to check it say 1-2 times a year, depending on circumstances. Beats 12 times a year.

I recently got a 2021 Toyota Highlander hybrid. It has a 1800W pure sine wave inverter that is connected to the very large 1.9 kWh battery. For emergency use, I have a cable from the Highlander to the gas furnace in the house. Will run the gas furnace with no problem. The neat thing about the Highlander, as well as most hybrids, is that the computer that monitors the battery when external loads are seen, it will start the engine to charge the battery, the turn it off when charged. If the Highlander has a full tank of gas, I calculated that it could run the furnace for at least a week with outside temps around 30 degrees F, given the particulars of my house insulation and high efficiency furnace. I really like diverse redundant solutions.... j

Or you could go the other way and use something like this on a Raspberry Pi:

;-) All sorts of fun with Django and React, cascading style sheets to get the perfect layouts for remote access on different mobile devices, and some interesting problems with guaranteeing safe shutdown of the Debian file system.

Exactly. A foreign air carrier, say carrying passengers from Tokyo to Honolulu and then onward to LAX is not allowed to pick up passengers in Hawaii and deposit them in Los Angeles, thus protecting the domestic HNL-LAX route from competition.

A common market does have some benefits- like cabotage and like EU SIM card/plans for visitors working all over the EU without extra charges instead of just in the country of sale.

That from someone from a country that lost a war in no small part because they built war machines that were too complex and over built so that they could not build enough of them to do the job. A country who's grasp of technology has been shown to be less than they believed on numerous occasions.

Yeah, we make technology that is temporary because ultimately, all technology is temporary. Ask the German solar industry. They can explain temporary to you.

I always wonder how easy it would be to get propane in a pinch. Gasoline will always be provided because it is needed for so many things. Propane is used by a very few for heating and even fewer for electrical generation.

Have you driven a Mercedes Benz lately? Or at any point in life?

Same here. There's hardly any US source of solar panels left. Sadly. Same in Europe.

Yes, that is a good idea. However, for me that would mean a huge learning curve. Making an analog controller is easy for me.

Because it is the least expensive :-)

Propane has become very expensive where we live. Plus then you either need to buy/keep/store bottles unless you have a specialist plumb in a tap and pipe (more $$$). Then try to find a dual fuel carburetor that fits your particular generator. AFAIR ours uses a 80ccm Yamaha-style engine.

Anyhow, I don't mind starting it once every 1-2 months. Just have to be careful schlepping it, on account of my bad lower back. I like to test important things regularly so I can be fairly sure they will work when needed. Smoke detectors, generator, CO detectors, brake lights on cars, sprinkler systems, et cetera. It's just a checklist routine.

Having a hybrid like you do would be cool. However, given that I drive less than 2000mi/year (the remainder is spent on one of my bicycles) it would not make financial sense at all to spend lots of money on a hybrid.

Some day I might get a LiFePO4 battery so it can run stuff a bit longer than a UPS can. Or plumb one of those into a UPS.

Have you driven a Lexus? That is a nice car. So is my Tesla. I don't want to hear any trash talk from Euro-trash.

So clearly no basis for trash talk from you.

JFTR I am an American. WRT to world war technology you might want to brush up on "Operation Paperclip". There was a reason for that program.

Fact is, the electric infrastructure in this here high-tech region of the US is the pits. 5-10 power outages a year is something I've only heard of from people that lived in countries like India, Pakistan or Romania.

Our last outage was ... <drum roll> ... yesterday. All it took was a little wind. Pathetic.

When a region has high rates of power outages like they do here in Puerto Rico, I figure it's on the users who don't make it a priority to push on the politicians to push on the utilities. Here it seems to be a bit cultural as they've put up with it for so long that everyone feels it is pointless to make the effort. What's your excuse?
