Crypto currency mining

[ulfilias]

Hi there,

My second S7 (2 cards) i brought home and tried it in my server room (tiny bedroom, holds my music server and various old tech junk. It's heated the house over the cold spell for a week or two, but it's definitely not silent even on the 33% fan i've had it on. With the door closed it's temperatures were getting a bit high (70ish). I know the limit is 80, but i'm not for overly stressing kit and temps a longevity killer too!

So i picked up a £15 TP link wifi extender with ethernet port and thought i'd try it in my internal garage. Had to use the web interface to set it up, but it's now in my garage along with the Antminer. It's somewhat cold and the garage is a less insulated space though being 3 joining walls it's also not bad.
Can't hear it inside apart from the reboot cycle and have dropped the fan to 25% and after an hour it's running at a mere 63 degrees on both cards

Summer may need adjusting but for winter i think i have a winner. I wonder if i could put a switch off that port and run a few as they take very little bandwidth....I do actually have an old BT U rack in there from an old hifi/cinema kit rack in my old house (i needed one that i could dismantle to get up stairs in this place) that has a nice power distribution block and some shelves and could make a decent mining rack and may baffle noise to the outside.....I also wonder about insulating the tin door....the garage is storage as getting an A8 in and out would be....interesting!

Noob question: could you buy BCH on Bittylicious and have it sent directly to Bitmain's payment address, or does it have to go to a wallet first to then send it on?

BCH is why I haven't bought anything from Bitmain yet. The first time I tried to buy an L3+ it took so long to get GBP in to the system to buy BTC they had sold out. Then they switched to BCH so I gave up. I may have another look in January when Coinbase introduce support for BCH.

I must admit this is something that I wondered, however it's NOT the way i did it. Got BCH in my wallet with a bit of headroom (~£1400 rather than ~£1350 needed) and then sent it to Bitmain.

Once registered on Bittylicious with passport and stuff i had enough purchasing capacity to do it and it was surprisingly quick, so I placed a Bitmain order getting a BCH amount, made a Bittylicious transaction to my Coinomi wallet (multi currency, quick and easy, but not really long term holding). Got the BCH and then made the Bitmain transaction well within the time limits!

Whilst i could see sending from Bittylicious to Bitmain working, if something goes wrong it's more complex to unravel

If you have a spare 2 hours you may find it interesting

Thanks

I think I started watching that interview a while ago then forgot about it.

I could watch Andreas' talks and interviews all day long if I had the time. It was nice to hear about the overwhelming support and donations he received recently; I think he thoroughly deserved it.

I think I've mentioned this one a few times previously but it's well worth watching if you haven't yet seen it:

It's the London Real interview from January of this year. You'll need to register with London Real to watch the second half but it's free to register and watch and they do interview a lot of interesting/inspirational people.

I watched / listened to that the other night. Definitely interesting. I've watched quite a few of his things now. Will have a listen to that Joe Rogan one as i've heard mention of it. Nice to see the comunity support one of it's biggest stars too. Must admit i expected him to be pretty wealthy. It makes it all the more interesting that he wasn't pushing things to make money, but he genuinely believed in it

I've played with powerline and they're useful. I'm generally not a huge Wifi fan and prefer a wired connection if possible, but no obvious cable route for that. I'm going to have another play with one of these at work as i've two factories next to each other and that won't powerline. Shame!

Advantage of using a wifi booster/adapter in the garage is it'll give better network coverage in the kitchen next to it for my Echo and when the GF is over who has an older phone without unlimited data

A wired connection is always the best option, if practical. And, for my business customers, wired Ethernet is always my first choice. When a wired connection is not possible, my second choice would be powerline adaptors and WiFi last. For the latter, UniFi make what are probably the best business-grade wireless access points you can buy. A single UniFi Pro WAP will easily cover most houses, but you can add a second or third unit if you want consistent coverage without any cold-spots. If it's difficult/impractical to run an Ethernet cable out to the UniFi WAPs, you can plug them into powerline adaptors instead (I have a few installations like this and it works quite well).

Powerline adaptors will only work on the same electrical phase so it can be a problem getting them to work in factories, where it's common to have multiple phases. If the individual phases come together at some point, such as at an electrical distribution board, you can use multiple powerline adaptors to 'step across' the phases. What you essentially have to do it create a link, using two additional powerline adaptors, with an ethernet cable between them -- one adaptor plugged into one of the phases and the second adaptor on the other.

Thats a fantastic interview and a real eye opener

Should work. As you say, they do use very little bandwidth. Have you considered Ethernet over Mains adaptors (aka 'homeplug' or 'powerline' adaptors)? Assuming your garage is on the same phase, sending it over the mains is usually more reliable that WiFi, and can sometimes provide greater bandwidth too.

As Lee says, it should work but probably best to send it to yourself first in case anything goes wrong. It could be difficult to rectify if Bitmain claim the funds aren't received or are insufficient.

I would just buy a little more than you need; It only takes a few minutes to install and setup a new BCH wallet.
