Way better to use your old junk. I like that youre make your own home battery, ive considered it. I have solar installed and would love to not consume grid power at night. I'm thinking of installing a bank of lead acid batteries under my ground mount solar that would dump power into my home at night.
Thank you for putting into words what ive subconsciously been thinking for years. Every search result prioritizes videos at the top and I'm still annoyed every time. Or even worst I have to hunt through a 10 minute video for the 30 seconds of info I needed. Stoohhhhpppp internet of new! Make it good again!
So, I design battery packs for a living. 115F ambient operating conditions are doable assuming you dont add solar loading. Can you paint your enclosures white? Or cover them? A high quality 18650 will operate fine up to 50C especially with a very light load and a low charging current. Do you have more details on your setup, chipset and average load?
Other elephant in the room is how healthy is the dad? A super motivated, athletic and engaged older dad is still better than an uninterested, over weight, young dad.
I used it many years ago, perhaps 10, and started using it again because it allows me to rename PWAs. I have four instances of Frigate running for various locations and now i can edit their name based on location.
I noticed the last modified date on some of my mp3s recently and realized almost all of them are old enough to drink and some are nearly 30 years old :(
Most electric vehicle motors (or any motor, wind farms, cordless drills, etc), speakers, and medical MRI machines need them and lots of them. Kind of important and America has been asleep at the wheel on this topic for decades.
That is not correct, you won't get a random lower voltage. You are correct that thw PD supply needs to support the voltage but PD always starts with 5V for backwards comparability then digitally its negotiates the PD voltage it wants, if it asks for 12v and its not available it with just stay at 5V. It won't spit out the closest value unless the device asks for it. Its a very strict and wonderful standard.
It all depends on how efficient your heat pump is and how efficient your gas boiler is. Gas is not always most efficient. In my house, down to about 40F my heat pumps are more efficient in terms of monthly bill. Below 40 gas is cheaper. I have a 95% efficient tankless boiler and SEER 20 mild temp heat pumps. Your millage may vary, if you had a 80% efficient boiler heat pumps are going to be way better.
I thought it was a joke until someone at my company gave a company wide presentation on how to use AI to accelerate coding and st several points flat out ADMITTED he didn't know what the hell it was doing but you just need to 'baby sit' it and you get useful scripts out of it. I'm a hardware engineer and I wanted to scream at him.
Check the power supply too. Those mini PCs just use a cheap laptop power brick and sometimes they can't sustain their full output anymore. I had one server constantly crash and once I swapped the power brick I never had a problem again.
