If i found a genie, one of my 3 wishes would be that reddit was viewed like Wikipedia. It should be a non-profit. I’d gladly donate to keep the servers up. I do that for Lemmy now.

If I want to know something, I’m either looking at Wikipedia for general information, or reddit for specific. The odds that someone else has asked the same question on reddit it weirdly high. Even Google acknowledged that there search results went to shit because of the blackouts. How did we let such a wealth of knowledge get caught up in profits.

I love Wikipedia. Even if it has flaws, it’s by far one of the best things we’ve created a humanity.

Up voted for this. I have a bunch of Yolink products. It all works seamlessly. I’ve got motion lights setup. I have my bathroom exhaust fan set to turn on at a specific humidity level. I’ve got their door locks, garage door opener. Hell, I’ve got the float switch set to tell me when my dogs need more water.

They have so many products and they all work together very well. It truly feels like a smart home now and it’s all the same brand so I don’t have to worry about compatibility problems or using a third party software. I do have them linked to home assistant for the few things I have from other brands. But I can’t reccomend Yolink enough

Ha. That will be wiped off? We are actively watching a mass extinction occur. It’s not going to happen. It already is

I wish I had an answer to that. For me, it’s knowledge and recognition. Having an open mind to hear both sides of an argument and trying to focus on facts, not “what ifs”. Then paying attention to not just what’s being said, but how it’s being said. It’s pretty easy to see when someone is trying to get you emotional rather than logical,but you have to be looking for it.

When I hear a politician say “they’re trying to take away…” or “they want you to…”. That’s them trying to make you fear the other side. I don’t give a shit if you’re left, right, capitalist, communist, or a dictator, if you’re goal is to make me fear what the other side will do with power then you’ve already lost me. Because I know, that really you’re afraid to lose power and so you make other people afraid too. Unfortunately, it works for way too many people.

Eradicate fear.

Fear of losing power. Fear of “them”. Fear of going to hell because you didn’t convert someone. Fear of lost resources.

It all boils down to fear. The problem is that fear is contagious. It’s easier to convince someone to back your side if you make them afraid vs hopeful.

Transformers raise or lower voltage of ac circuits. They also do the opposite to current, e.g. Raise voltage, lower current.

The rectifier makes all the voltage positive (or negative, but all the same). So yes, AC -> DC

The filter basically uses inductors and capacitors to act as storage. Using capacitor as an example, it’ll start charging when the wave starts to rise. once the wave goes down, the capacitor discharges which keeps the output more positive. You can see that in the image by full humps before and partial humps after. It’s still bumpy, but it never goes to zero.

The regulator can do a couple of things, mostly it’s used to ensure a constant output. In it’s most basic, it’ll be another diode that if voltage goes above a certain threshold, it shunts it away from the load. So if the output of the filter had a minimum of 5 volts and the regulator was set to 5, you’ll end up with a constant positive 5 volts because the diode is shunting away all the extra voltage.

Regulators can provide both over and under voltage protection in case there is fluctuations in the circuit.

Kind of. You’re on the right track.

What you’re missing is that there is a loop. Imagine a resistor being connected to negative and positive of the load. Since it’s about relative voltages not absolutes, d1 and d3 both conduct. A positive on the triangle, or a negative on the bar will make them conduct. For electricity to flow you must have a loop from source to load and back to source. So current would flow from the source through d1 through the load through d3 and back to the source.

Hope that makes more sense.

You could remove d1/d4 OR d2/d3 and you’ll have a half wave rectifier, so you’ll get every other peak.

“DC or direct current is instead just a constant horizontal line.”

Your explanation is totally correct. (I replied as well just to break it down a little further for OP). I know I’m being a little pedantic, but DC does not have to be constant. DC can also pulse and change. The main difference is whether or not the signal remains positive. If it goes negative, then it is AC. The change in polarity is what matters, not how constant it is.

Think about the circuit over time. The sine wave on the left is the input.

When the sine wave is positive, the top wire is positive and the bottom wire is negative. That means d1 and d3 are both positive and d2 and d4 are both negative.

Diodes “forward bias”, meaning they allow electricity to flow, when you have a positive on the triangle side. This also implies a negative on the straight bar side. If the positive is on the straight bar side, then it won’t conduct. You have to have a negative on the straight bar side.

Note: Keep in mind positive and negative means in relation to each value. So if one side is 5 volts, and the other is 0, then the other side is negative compared to the positive side.

So with that in mind, when the sine wave is positive, greater than 1,then d1 and d4 are conducting (there an implied loop on the left side).

When the sine wave is negative, then d2 and d3 are conducting. Because these two diodes are flipped, the high value goes to the top wire on the output which is now seen as a positive. The input is different, but because you’ve flipped the wires, the output is still the same. Now all current flows in one direction no matter the input. AC is now DC.

Shorter verison: positive side of the sine wave makes d1 and d4 conduct. Negative side makes d2 and d3 conduct. Since d2 and d3 cross over, they effectively turn the negative into a positive value.

Unless there is a transformer. Also, it may just catch fire depending on the input voltage

The app looks great! Feels very fluid.

I have only three requests:

• make it FOSS in spirit of the fediverse (obviously you don’t have to, that’s your choice)
• give me a way to download pics from inside the app. I very often download memes and share them in other chats. You’ve got open external, which works, but it’s an extra step. Downloading in app would just be more convenient.
• lastly, give me a way to buy you a beer 😁

Yeah I’ve been about 50/50 with plant based beef and chicken. I’m extremely excited for this. Might be the final nail in the coffin for Big Meat

Maybe, but unlikely. I’ve seen a couple articles about it being likely next year. Nintendo wants to sell most of their current stock first.

Here’s a link to most of the rumors

I’m down to help out. I’ve never modded before, but am willing to try it out. I’d like to help the fediverse grow and I love questions.

I work nights so I usually wake up between 4-6pm and go to bed around 10am. This is all PST.

Also, I agree with the rules.

This right here. Everytime I hop to a new service, I use soundizz. Works perfectly for me and I have a lot of Playlists. The free tier is pretty limited. I think it only let’s you do 50 songs at a time, or something like that. It’s worth it to pay for one month, transfer everything, and then cancel.

Amazon music is decent. Apple music is pretty good. Tidal is awesome, but last time I used them I thought their algorithms were kinda weak.

I actually use YouTube music myself because I have YouTube premium. I also use a yt-dl to download my music, and have it all backed up to a NAS.

They should go non profit. Sure there are memes and stuff. But I’d be willing to bet the main reason people use the site is for hobbies and asking questions.

If reddit crashes, no one is gonna give a fuck about the lost memes. We will care about not getting an answer to a question that can’t be found on Wikipedia or a manufacturers site.

If they did a banner like Wikipedia and just asked for donations to keep the servers up. I’d pay. Plus, they are literally using volunteers (mods) to run the site. Reddit is already set up to be a non-profit.

Chrome has a way back machine extension

I’ve never actually used it though. Never had a reason till now
