1  Economy / Service Discussion / Anyone able to pay their MyRig (formerly BitmainWarranty) hosting bill? on: February 01, 2018, 06:07:45 PM
Looks when they shut down bitmain warranty, they didn't migrate over all the hosting plans they sold. Has anyone been able to pay next months bill?
2  Bitcoin / Mining speculation / KryptMiner - 20th/s @ 800w (a new magical miner / scam?) on: January 11, 2018, 05:26:26 PM
Seems like there is a new magical miner:

The KryptMiner PowerProcessor Card is at the heart of every KryptMiner system and features its own super-efficient switch-mode power supply and utilizes a proprietary TSMC 16nm FinFET ASIC (Application Specific Integrated Circuit) low-power number-crunching core technology. Each PowerProcessor card has 200 such ASICs sharing the work load and crunching our proprietary algorithm for optimal performance.

The process is overseen by our patent-pending PowerFace front-end management system that connects directly to a Gigabit Ethernet for instant delivery and features a Field Programmable Gate Array (FPGA) reprogrammable management processor to ensure KryptMiner never becomes obsolete as mining evolves and allowing you to stay ahead of the game today and long into the future.

Specs from site:

Of course, it is likely a scam, as their address is a Regus business center. Pricing says its $2k per 20th unit.

Also, based on what page you look at, the power draws between 600, 800, and 1kw.

SOLD- thanks!
4  Alternate cryptocurrencies / Mining (Altcoins) / FutureBit Moonlander 2 USB Hubs Thread on: November 24, 2017, 03:14:18 PM
Figured I'd start a thread for these.

First, the best resource possible is Sidehack's USB hub thread:

Things to look for on the hub:
  • Provides at least 1amp per port
  • Has a way to hook up to your Pi/PC (this is sometimes described as  "Sync" not just charging)

Here's my learnings from playing with those that also apply to the Moonlander.

Budget Hub for 3 or fewer Moonlanders

Pluggable USB hub -

These have 3 voltage regulators that are shared by the ports next to each other, so you can only run at max 3 of the Moonlanders. Put one on port 1, port 4, and port 7.

Hub for 3-10 Moonlanders

Sipolar 20 Port -

This hub can power up to 12 moonlanders, due to the size of the fan. It has two USB 3 ports to connect to your PC or Pi, so be sure you plan that. Some people reported having trouble getting the Pi to recognize it, but if you have this issue, plugging the USB3 from this into a cheap USB hub (like an Amazon basics 4 port USB2 hub) and then that into the Pi works.

Other hub:
Eyeboot 19 Port 40amp -

Hub for 10+ Moonlanders

Eyeboot 49 Port - or

This bad boy can give 1amp to 21 Moonlanders. It is expensive but high quality, and will run a ton of Moonlanders. Note that you need an external ATX power supply for this.

5  Bitcoin / Mining support / Running externally powered fan? on: November 20, 2017, 02:43:24 PM
Like the idiot I am, I fried the fan control on my eBit miner when I was trying to repair a broken fan on it. (I had a bad crimp on one of the pins that I didn't notice until it was too late, saw the spark once it turned on and immediately shut it down.)

However, the miner works perfectly fine, just with no fan so it quickly gets to it's shutoff point of 70C.

I have the right kind of fan, high static pressure, all that good stuff, and I wanted to wire it externally and just run it at 100%.

Has anyone wired up something like this? It's your standard 4 pin high powered, 12v, 3amp fan - so those case fan to USB converters definitely won't power that.

Any tips from the pros on here?
6  Bitcoin / Mining support / Making your own PCI-e cables? on: October 23, 2017, 01:49:54 PM
I've done plenty of ethernet and phone cables in my life, but I was wondering if anyone knew the right tool to crimp PCI-e cables?

Any tips for the wire gauge to use as well?

Would this work ok?
7  Bitcoin / Mining support / Will an Avalon 6 controller support an Avalon 7? on: August 17, 2017, 06:53:11 PM
Just curious if anyone has experience with this? I have a A6 controller with two units. Will it be able to use the A7?
