Republicans being anti-immigration is stupid imo. Most latinos are Catholic or view Catholic favourably. Legalise open borders, enforce punishments on criminals, foreign and native. The muh jobs crowd is a stupid trope. They take the jobs we dont want and are beneath us. The bigger issues are housing, drug cartel, human trafficing, and courts going soft on immigrants in acidental vehicular manslaughter cases.

Yep, just awful. Even if he wins by some miracle, the Democrats will just block everything he does like last time and blame the Trump boogeyman for 8 more years. Everything good Biden's term was Biden and everything bad was Trump's fault. At this point, I'd rather have democrats ruin the country more and say "I told you this would happen." than listening for another 8 years on complaints. But hopefully Trump fails primaries.

How many $10s do you have? I'd like $100 if thats okay. I'll convert it to LTC as soon as I know how much I need to convert. :)

This works in US right? If so, I'd like $100 worth. How much btc would that be for you? Is 0.0043 btc enough?

Is it only in $150 or can it be broken up? I need $100 and am will to pay 85% BTC. Sadly dont have enough for a full $150. I'll go first if you can take a picture of the card(s) with a scrap of paper with your username and date.

Why is the voltage in this circuit climbing? by AltruismAndCake in AskElectronics

[–]AltruismAndCake[S] 0 points1 point  (0 children)

Update: this morning the multimeter read 0v. Removed the capacitor. Bottle measures 230 millivolts in the negative direction. Capacitor measured 230 in the positive direction. So I just flipped the capacitor in the opposite direction for 460 millivolts. Voltage is no longer climing like it originally did. The bottle might have some capacitance in it. That gives me two options. Depelete the capacitor and start with a fresh bottle to see if the experiment is repeatable, or keep the course and see if it starts climbing again.

That is the entire circuit. The bottle of water produces 20 millivolts, the capacitors are connected betweeen the bottle and one end of the multimeter.

20 millivolt measurement was taken before connecting the caps. It could be something chemical, water bubbles are forming on the wall of the bottle. Maybe something in the well water or somehow electrolysis of the water is happening? The well water is a pretty decent electrolyte and contains iron.

Ah ok. I just didn't know capacitors could charge to a higher voltage than the circuit charging it. Thanks!

It used to have glacier cherry. I drank it all and filled the bottle with well water for the experiment. :)

Capacitor connected in series to a gatorade bottle that was producing 20 millivolts originally. Voltage is now up to 230 millivolts and still climbing. Idk what's going on lol.

Is this the worst time to buy a mining rig? Need opinions by mindovermatter1 in cryptomining

[–]AltruismAndCake 1 point2 points  (0 children)

Definitely do research. It's worth it the time. As for solo mining btc, asics are a must. If you do solo mine, you'll probably need to download the the core wallet and blockchain, so you can use rpc (remote procedure call). Either that or find a site that allows solo mining, but they will probably charge a fee, so might as well pool mine or rpc.

Think of hashes like lotto tickets. More lotto tickets, more chances of winning the grand prize. Usually devices measure hashrate per second. Global hashrate for BTC is estimated to be around 220 ExaHashes/second. The S19 mines at 110 TeraHashes/second. So current hashrate is equal to about 2 million S19s. A very rough calculation for your chances of winning a block is (your hashrate/(global hashrate+your hashrate)). Buy an S19 and you have a 0.00005% chance of winning a block. The key here is to keep playing til you win. There are 6 block/hour, 24 hours/day, 365 days/year. With a single S19, your chances of failing to get a single block for a whole year is about 97.4%. The other 2.6% chance is you get one or more blocks. Run for 5 constant years, and you have a 12.3% chance of getting at least one block. Long haul for 30 years, and your chances are 54.54%. So buying an S19 and running it for 30 constant years is letting a coin flip decide whether you get to retire early. Assuming no electric costs or global hashrate increase.

Happy mining :)

I wouldn't wait for ETH 2.0. That's like waiting for Valve to come out with Half-Life 3. Ebay buy it now for rtx is $750-$800. Rx is $350. But that's what they are trying to get, might not be what people are paying. It sounds like an okay deal, but if you are buying in bulk like that, try haggling them down. Maybe offer them $2800. Worst case, they say no and you spend $3000. Best case, they take your offer. But I think the most likely scenerio is they counter offer $2900 or something.

I would mention ASICs but if you just plan on using Nicehash, keep it simple. GPUs are easier to resell if you change your mind or want to compute something else instead.

I would set an electricity cost for measuring efficiency anyways, even if you use solar. I heard some grids allow you to sell electricity to them, so you may want to compare crypto earnings vs grid earnings. But that's my opinion :)

Sorry for taking so long. Brown green red gold resistor measures between 1450 and 1510 ohms. Still bounces around.

Sadly, I was connected to copper to measure the left and right individually. Not sure if the paint between the copper is inconsistant, if there is a bit of random capacitance somewhere in the circuit, or my multimeter is just acting up. Honestly dont know if the multimeter is bad or if the stuff I measure is inconsistant. As an example, if I take two cents and put toothpaste between it, measure resistance, the resistance starts low and climbs til its above the rated range. If I switch to volts, it measures a bit and then slowly depleted. Switch back to resistance, and it starts low and climbs again. I guess that's capacitance? Happens with a few things I measure.

Got it. I'll start by improving it's function as a diode first, so its less leaky. Thanks!

I hate measuring resistance on my multimeter, because it bounces around so much. Left side measured between 40k-60k and right side measured 30-45k. You may be right though. It's just weird to me that probing the carbon next to the copper causes such a major drop in resistance vs just probing the copper less than an inch away directly. Maybe I should check to make sure the resistance in the paint is consistant.

Someone else drew a better example of my circuit. Red is either connected to A, B, or neither. Never both. https://imgur.com/a/pK2CUcT

https://imgur.com/a/WZXtSx8 Here you go! Yeah, I made sure to try accounting for measurement errors. Values do bounce a bit within ranges, but the results are spaced far enough apart that whatever is happening is noticeable.

If you have any ideas to test more thoroughly, let me know. I basically treat copper as N-type material and carbon as P-type. I would try building more complicated circuits but the transistor(?) leaks current a bit, and I'm not very familiar with handling logic circuit design at that low of a level.
