Dimmers will typically use a triac which cuts up the sinusoidal waveform. It doesnt actually lower the amplitude per se, but it limits the fraction of the time the waveform is on. Kinda like this. This means that a lot of the time the led isnt gettingas much or any power. The average power will be lower, and if the LED driving circuitry isnt designed to compensate for this, the LED will flicker.

Clarification on triacs: they get turned on a certain fraction of the way into the cycle. Triacs will stay on until the voltage across them is 0. Conveniently the zero-crossing of the AC wave (when the wall voltage crosses zero to start foing negative or from negative to positive) does just that.

Which also drops from 30% to 25% after $10M and to 20% after $50M, giving a grand total of:

Why dont you go tell [the] paralyzed to just get up and pick something up off the shelf. Its so easy, isnt it? They just made their mind up to be dead weight and have people take care of them.

Just because you dont suffer from something or cant physically see it doesnt mean its not real, and just because you are capable of something doesnt mean everyone is, even if they WANT to be capable of it.

A car output is going to be ~12-14Vdc and the solar panel at 24V. You do not want to connect those two together. Ideally you have some kind of switch that connects the input to the bluetti only to the solar panel or only to the car outlet, and to the car output only if it is present. You can probably use a contactor or a heavy duty relay that is 12V and connect the NC contact to the panels, NO to the car, and COM to the bluetti. Add a capacitor to dampen spikes whenever the system switches and connect the grounds together. A bjt jank, and also have to check the relay ratings / coil power usage

Coal plant burns coal to heat water, makes steam, and the steam powers a turbine to produce electricity. A nuclear power plant uses nuclear fuel to heat water and produce steam similar to a coal plant. It may do this indirectly (e.g. second loop between the nuclear fuel and water loop to prevent the water becoming radioactive). This means that to build a nuclear plant you essentially need to build a coal plant, and then also the nuclear reactor and safety stuff, which makes them more expensive. Since coal plants are being turned off anyways, it might be more cost effective to just retrofit old coal plants so the only cost is the nuclear reactor side of things (plus any necessary maintenance and upgrades)

Behavior is called mobbing

Its not worth it for the predator animal to go after a bunch of smaller birds that are harassing it so they tend to leave. Its also done to steal the predators meal when they leave or to distract it while another bird steals its food. Also draws attention to them to prevent them going stealth, which can affect bjrds like owls, who tend to be victim to this type of attack from prey birds. This makes them leave because their main weapon is stealth and when their cover is blown, they will have a harder tome catching prey (including the mobbing birds’ babies)

It’s a lie because Im too dumb to prove it

There’s an RFC for (per post?) tags but not sure what ever happened to that

Probably something to do with the great depression and needing to make cheap foods interesting

Something to do with women having to make things look less lazy/not just serving ready made things, and like they put work into making food in the post ww1 period. Recipe books tended to have the crazier stuff trying to get you to use more of their other products

Qube and anti-chamber if you’re a fan of superluminal

It is an N channel FET. The concept is called “bootstrapping” since Vgs needs to be greater than Vth for the MOSFET to be on. When the FET is on the high side and you want the full 9V on the output, you use the diode to charge the capacitor, and the other side of the cap is 0V. Then, when the other side of the cap is connected to 9V, the charge on the cap can’t go anywhere so the voltage on the other side jumps to 18V. This creates a Vgs of 9V. Ideally you would have something better to drive the gate to fully turn off the FET, but I just used a quick and dirty driver where the bootstrap capacitor directly feeds the gate instead of being the input to the driver. Because if this, the Vgs doesn’t drop completely to 0

You could use a single MOSFET on the high side of the divider and use a cap + diode to boost the voltage and fully turn on the FET:

My gate driver is fairly crude but you could probably make something a bit better with a PNP transistor and either pull it down or leave it floating, or instead use a szaiklai pair
