Re: Power consumption 220v versus 110v question

The stats page in the Spondoolies web front end reads the usage at the chips themselves, It does not account for the control board, fans, or overhead. You're probably not overclocked (And shouldn't, these days, not without replacement parts available!) So in all, you're probably looking at around 1100 at the wall for your 880 running a partial miner.

Re: Spondoolies SP-30 ?? Help!

I use 10 amp rated C13 to C14's, and run them to APC power distribution units, which have a C14 plug for the receptacle and a NEMA 6L30 locking plug for the 230v incoming.

Of course I'm a stickler for cable management. A 3 prong regular dryer outlet will work fine. You only need single phase 230v, not 3 phase 240v.

SP30's won't run on 110v. The power supply isn't getting enough juice to feed the miner. The fans will kick on for the supplies, but nothing else.

Re: [1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

Does the amount of network traffic used by p2pool bother anyone? I have some ideas for how to reduce the amount of traffic (without improving propagation performance), but the traffic doesn't bother me, so I haven't made implementing it a priority.

The other project I have in mind is trying to improve fairness independent of performance by using some sort of share DAG (e.g. with uncles) or one of the other ideas mentioned in https://bitcointalk.org/index.php?topic=18313.msg19248232#msg19248232. That's going to require far more work than the network traffic reduction, though.

Alternately, I could work on polishing the current code a bit, merging into the main p2pool repo, and organizing the community to upgrade. If I do that before the fairness work, that means that we have to do another big upgrade later.

Thoughts?

The amount of network traffic can significantly affect users who are subject to data limits (Comcast users) and those who also run full node core. I know I bumped against my data ceiling last month. Reducing it slightly would definitely incentivise me to maintain a full running p2pool node even if I wasn't hashing at the pool. As with most things bitcoin, if it doesn't harm my wallet, I'll help where I can.

This seems like yet another example of people not understanding what we are actually doing. Shocked
No, I thought it was the former, but it had me questioning a bit. Technically the scenario of paying more for bigger shares would not be logical as the guy/gal/dog who submits the winning share would get a larger percentage of the proverbial pie.

I don't understand every nuance, my specialty is hacking and fixing the mining hardware. That I'm good at :-)

Technically, the guy/gal/dog who submits the winning share DOES get the larger percentage of the proverbial pie, or at least used to, in the form of a 0.5% incentive. I don't know if that's still coded in or not though.

From the P2Pool Wiki: A subsidy of 0.5% is sent to the node that solved the block in order to discourage not sharing solutions that qualify as a block. (A miner with the aim to harm others could withhold the block, thereby preventing anybody from getting paid. He can NOT redirect the payout to himself.) The remaining 99.5% is distributed evenly to miners based on work done recently.

Can someone explain the drop in hashing power pointed to p2pool?  I saw someone else mention it was up to 12PH and now it's hovering between 2-3PH.  Did I miss something? 

Everyone go back to a centralized pool?  What the hay??

Rentals are only sustainable if they're hitting blocks on a regular basis. The price of rentals also rises with demand. Most likely scenario is the rented hash that was contributing to P2Pool ran out and the cost vs. profit was too great a ratio to justify another week of 'maybe a block'

Imagine an add-on to automobiles that mines bit coins but doesn't require any extra energy as it would be using any wasted energy the car produces (if that is even possible).

Turbocoin!

It'd be mined through the wastegate and blow-off valves on Subaru WRX's and Mitsubishi 3000GTs!

Re: Rosewill Capstone 1000w Gold PSU for Ant S3
by
Mister S
on 11/07/2014, 04:42:49 UTC

So since there's only 3 of these would I be ok to run one overclocked using 2 cables? And the second s3 on the third?

The one you overclock I would suggest upping to 12ga wire on the main, and 14ga on the extension, but the wattage is there, so you could do it easily. Remember, 5% +/- on the wattage draw for estimates is fine until you burn up a brand new miner. Start at standard clock and if you have an amp clamp, use it. I would NOT suggest overclocking both on less than a 1200 watt though.

Also, the Rosewill is rated at 100k mtbf at 25c. but it lists the supply at 100% rating stable at 50c. E-mail them and ask them what the average lifespan is at 40c.

You don't need to plug all four PCI-E connectors into an S3 unless you intend to overclock it anyways. If you're going to overclock, this is a good supply to do it with though, 83 amps to the 12v rail.

AWG size limits your wattage, but from the pictures that looks like 14ga to the connector going down to a short run of 16 gauge. If it's not, this is the minimum you should run in any circumstance.

Re: Why does my PC shuts down when Technobit HEX 16b gets plugged in?
by
Mister S
on 11/07/2014, 04:14:29 UTC
So are you hinting that it might be a problem with USB cable? I don't have a multimeter, but I'll get one. If there is a short, will changing the cable fix the problem? Newbie here.  Wink
Yes, he is saying that there could be a short in the cable, but it could also be on the HEX 16b board. Just wondering, does the problem also occur when your HEX 16b isn't plugged in to it's power supply?
I personally find it a little odd that a USB cable would be defective in such a way that it would cross 5v and ground. The PWR and GND wires are on opposite ends, but I suppose anything is possible.

Actually, I was hinting that the problem might be at the usb connector to the Hex16b. The 5v usb power is close to the ground on another smd component. One stray tin whisker and you've got continuity between 5v and ground. Believe me, that's nothing on Technobit and everything about modern materials.

When you check the cable, what you're looking for is continuity or resistance between the 5v and ground return terminals, tested at the same cable end (The one you plug into the USB port of your PC, it's the easiest to check). If you have continuity, you have a dead short. If you have less than .1 ohms resistance, you have a dead short. Check with the cable unplugged from, then plugged into, the miner.

The second thing to check for is a short to voltage. With the miner's power plugged in, you should check the voltage at the usb cable. 12v means an obvious failure on the board, and one that most miners without an electrical engineering background might not be able to repair.

Put a multimeter across the 5v and ground of the usb cable you're using, I'm betting there's a short somewhere. 5v across the ground will cause the power supply's power protection circuitry to activate.

Simulated racing, go kart racing, and actual racing are two entirely different things.

What class would you be racing, and style?
Drag, circle track, rally, baja?
Do you have the technical expertise, time, and room to gut and rebuild a car?
Do you have a shop willing to put time and, likely, parts, into your new race car?

After getting the vehicle, how do you plan on promoting and racing?

Your estimate of 2800 usd for a race ready car is ridiculously low. Multiply by 2.5.

What's your local track? Do they advertise or is it just 'come as you are'?

Keep in mind you're representing bitcoin when you decide to race with that logo.

Probably don't want to come in anything less than 5th in local circle track.

I know someone plotted the EXIF paint correction data, but is there any chance someone could go point by point? not in lines, but x coord, y coord with that info?

50 lines of signal strengths.
1 line of just 02 repeated.

I think each 2 data point corresponds to the letter in it's line, and where they intersect is where we go, but in order. (Top to bottom, or bottom to top)

Yeah, sorry, this did end up being a false positive, I ran it through a hex editor, excised the parts that 'may' have been a 7z compressed file, no match to any known compression type.

Sorry, looks like the file is the file.

This is it.

(Also, to find some of these faster, notepad++ with little endian encode.)

I can confirm that there is a 7z file embedded inside the wow.jpg.

Seperating them, however, is a task I'll leave to others more suited for that task.


Sorry, false positive, but initially seemed legit.

Pixel by pixel analysis of the Hint image shows only one oddball. pixel 11 down, 29 across, is red. No other pixel in this image matches that color.

Other than that. I'm like a tree cut down. Stumped.

The more I look at this image the more I think of the old 'fold and decode' style messages you used to get in Cracked magazine. Where you folded an image at three points and it showed an entirely different image.

That's likely a dead end here. Unless someone can come up with a way to align the dots from the first image, or the unknown dots from the enderman overlay.
