Topic: KanoPool kano.is lowest 0.9% fee 🐈 since 2014 - Worldwide - 2432 blocks - page 1275. (Read 5352429 times)

guys sorry to post this here... but maybe you can help me out

Ive using 2 s7-f1 on kano for 1 week, but today i dont know what happened and 1 of the s7-f1 stopped hashing, and it shows hardware version x.x.x.x i updated to the lastest firmware, switched to another psu, restarted the miner, restarted the router and still the problem persists, any suggestion?

Where did 17JL go? We are missing him!

big boys are pushing out the s7's, a6's. Home miners with higher power costs can't really compete under these conditions.

107minutes on this network block

Difficulty goes up, coin price continues to drizzle downward slowly. 

Ouch, over 700% network block now after the diff increase...  Fun fun fun? 

We are officially at a Network diff of 217G...about 20 minutes ago...

Yeah...you betchum bad...that's got to do with wire size, though most likely, not circuits. I only use server grade, 1KW rack-type power supplies, with gridseed adapters and 14ga pigtails. I've found computer psu's to generally not be as well built, and often use a lighter grade of wire in their PCI leads, unless you pay a bundle for a platinum 1200w unit. 12vdc can weld a wrench to a battery terminal if shorted. Don't make the mistake of using too light a gauge. Similarly, a household extension cord is almost never rated at more than 15A (at 120v); if you run a 1400w miner on it, you're loading that extension to at least 93% of capacity, and I guarantee it will get warm. As an example if you pull 18 or 19 amps (by having a miner and perhaps another appliance on that cord) you won't blow the circuit breaker, but you'll perhaps burn down your house because the cord could get hot, melt, and start a fire. Sermon over.

oh oh, very bad... a cable was melting and burning... tomorrow i have to set up better power connections. 

That would be great! PM on the way!

Uh-huh...been there...done that...

Ya gotta pay attention to circuit capacities. My service here is 120v. I have only 30 amps of available service total. One S7 uses 14 amps. A typical household circuit (in 120v territory) is 20 amps. I currently run 6 S3s at home, but they only draw around 3.5 amps each, so I'm drawing around 19 amps for all of them; they're on two separate household circuits. I can't run the microwave without first shutting down two S3s. I ended up sending my 3 S7s to CryptoBoreas for hosting...that works for now.

I'm gonna take the time to photo my rack setup a bit later and post it. It appears to be a bit simpler...and cheaper. I've got (yet another) housing inspection tomorrow by a nonprofit co-op that the owners have retained to figure out how to finance upgrading the wiring in our complex so we can get 100 amp service in our units. Turns out that my blowing the main breaker for my unit several times around the first of the year got some positive attention. Additionally, another tenant bought a portable a/c unit, plugged it in, got it going, and then fired up their coffeemaker...and blew the 30-amp main breaker on their unit. I've been telling mgt for months that would happen.

Figure out which circuit breakers handle which plugs, and what your total draw is/should be for each circuit, when everything is turned on. Stay under 90% of that, and you should be OK for draw. If you run too close to the limit with only the miners running, then something like a frig compressor cutting in, or a microwave, or a vacuum, or even a hair dryer, could easily blow either a circuit breaker, or the main.

i have a way to show you

send me a pm I will do some photos
