Got my batch 3 tracking number this morning, indeed I will be receiving my batch 3 on the 20th when the batch 2's start shipping. IMO totally worth the extra $100, time will tell.

Any interest so far? I'm curious if you can change the ship-to address on the order, about the only way I would consider buying is if it is coming straight to me from Bitmain.

If the unit is being direct-shipped and you're okay with escrow, perhaps we can work out a price. Feel free to reply or PM me.

Yes you *should* get a permit in order to add a sub-panel, I have no idea what the fines may be for doing without as you will need (if I'm not mistaken) full electrical drawings by a Master (or at least Journeyman) electrician which can cost quite a bit. Based on experiences of other people I have talked to, the worst they will do is force you to tear out the additions.

The permit itself should only run you a hundred bucks, not including the planning and blueprint work which will be significant. Keep in mind this is issued by your Municipal Government, not the utility provider.

Based on this it sounds like you're better off than me, regulations are a bit stricter here. I wouldn't worry overly about doing the work, though I'm certainly not a contractor.

Modifying electrical so long as there is one layer of protection between the work and your meter (Your main breaker at your panel is more than sufficient) is not illegal, I took the risk on just making the changes as there's realistically only a small chance it could become an issue if I do a large contractor reno, or if I sell the house. Even in these circumstances I may be able to get the work permitted later so long as it can be inspected.

If for any reason you need to change the main panel, (assuming there's no shutoff between the panel and meter, which would unusual in residential) you're SOL and will need a permit without exception.

100% correct, I'm lucky enough that my business partner is a Red Seal electrician. We wired a 60A 240V sub-panel in a day to power the miners, cost us about $1000 dollars in materials (the 60' of 60A 3wire cable was $280 alone).

To power a miner with 240v you will need two breaker spots to fit one of these PER MINER




If you only have one (or zero) spot(s) available, you will need one of these:



Which will allow you to power ONE miner on the middle hookup (An antminer MUST HAVE a dedicated 15A breaker, for 240v those two 15A breakers MUST BE ganged together to prevent potentially serious damage to a power supply) and give you two 120v spot to replace whatever you had to move.

Hope that helps


Edit: Thought I should mention the top breaker will run you about $20, the bottom one is closer to $50

Nice short runs, that's a pretty handy setup you're running Never forget that "home mining is dead"  



I'll just leave this here....

You're too kind

Figured I would snap a couple pics of my nearly completed ventilation.

To be added: 2 more 8" fans to bring airflow to 1500cfm, the necessary two 8" ducts on the left side of the box.






Hand-made 10"x14" filtered intake, and 10"x10" hooded exhaust.





*Ignore the timestamp, this old camera constantly dies*

Thought I may chime in, mining in Alberta myself. Just about finished my mining box with space/power for 8 miners, working on some new pics of my finished intake/exhaust.

Here is 240v power for the miners, each unit pulls on a 15a double throw going to a simplex 240v plug.






If you're having a electrician help you out those simplex to 5-15 adapters are a bit pricey, but actually meet code in Canada, as you cannot wire up a 5-15 wall plug with 240v and have it pass an inspection.

I highly recommend the eVGA 1600w, they will power any GPU or ASIC rig flawlessly and with better efficiency than Bitmain's PSU.
I had one of these eVGA's spontaneously stop working, it was inconvenient but I got a new one from newegg in 3 days. 2 weeks later after spending $40 to ship the dead unit back to eVGA in California, I got a brand new sealed unit with a full 10yr warranty and altogether I'm extremely happy.

The best part is I have the spare PSU just itching to power an S9, just waiting for the price to drop a little bit more.....

Ooo jeez, almost hurt my feelings this time, always a pleasure when you grace us with your presence.

Nailed it, almost exactly two weeks.

Please read back through the recent discussions. If you have irrefutable evidence Slush is taking part in block withholding, or that there is block withholding going on, or that he is siphoning funds, you can post it here or in the Scam Accusations thread.

If you are here to spread FUD and make more nonsense accusations you can go to Kano's thread, you will be welcome there.

You don't want to mine on Slush anymore? No one cares, that's your choice to make.

6 months you say? inb4 their post-halving "oops we messed up" exit strategy.

0.098 is a beautiful number, not sold on grabbing batch 1 units with that price though.

+0.6 = Erumara

Thank god someone is prototyping a unit that runs on mystery chips!

Glad to see you have the "Buy one get the second half off" Just like all the reputable manufacturers!

Too bad you didn't post your BTC address, would have liked to send you coins already just in case you're not totally full of crap

Agreed, fueled generators are almost going certainly going to cost you more than it is worth to keep them running. You need a battery backup/inverter system to charge while power is up and discharge when it goes out.

Lithium Ion batteries are the only real option, I did a lot of research into viability of battery backup and it is unlikely to be worth it.

10kWh battery = ~$3000usd (I've seen some cheaper on alibaba)
Inverter = ~$600usd

Backup power (2 s7's @ 1250W ea)= ~3 hrs

Keep in mind they take time to charge up, if you're suffering clusters of outages (I would assume so, during peak usage periods) they're usefulness will be decreased even more.

Please do at least some basic research if you are going to make claims, you are not helping anyone.
