Sorry for lack of responding. I am the founder of HashRatio(Galaxy Dragonfly). You could reach my email : [email protected] if the email was bounced for [email protected]

How much does that unit cost?

I tried contacting hashratio by email but it bounced. Do you have another way up contact them?

Known problems:

P: Rpi is not powering up from single USB port
A: There are two USB ports on the miner, use the one closer to hashing boards to communicate with the miner, use the other one to power up Rpi through micro USB port (you will need additional male USB->micro male USB cable)

P: Miner is not working with full advertised hashrate
A: Use suggested pools with static difficulty 64 (polmine.pl, f2pool.com, ghash.io), other pools might not calculate shares properly.

P: I want to change my miner ip address
A: SSH into the miner, edit your desired ip address, netmask and default gateway (Ctrl+o to save, Ctrl+x to exit),

P: Number of hashing boards connected stays at 1
A: No matter what number of hashboards will be connected there will be 1 ASC shown on the mining dashboard, don't worry about it.
    Hashrate will be OK.

P: I want to change mining pool through web browser
A: There is no such possibility with ver.1 firmware, you have to edit cgminer.conf file.

 

By courtesy of Simon from hashratio.com I am able to post a review and setup guide for first, sample production run of their miners.
Currently they are to switching to production of 900 Gh/s AM's OS Cubes also based on 95 chips from AM.

Hash power: 740-780 GH/s
Power draw: 875-880W at the wall
Noise level: 55 db
Approx size: 28x15x34 cm.

What you will need:
-950W+ Power Supply (preferably server PSU)
-PCI-e plugs if you plan to use ATX power supply
-ethernet cable
-Rpi and 8 Gb SD card (depends on where you bought your unit)

Unit contains of two mainboard (backplane), 5 hashing modules with 2 aluminium heatsinks each, two y4574 fans (good quality Dell related), Raspberry PI, 8 GB sd card.
One Rpi is able to control up to 10 miners (over 7.5 Th/s in total)

WARNING: Miner has two 8 pin plugs on the mainboard, however 8 pin pci-e plug fits there, you can not plug it directly in there!
Polarisation is different than at regular PCI-e plug, and it might destroy your miner. If you plan to use PCI-e plugs please mount them at the end of cables provided by hashratio.com according to right polarisation.

It might be possible that you will need to flash SD card with firmware, you can download it from here:
http://pan.baidu.com/s/1eQBsRxK
after downloading write image file to the SD card with win32DiskImager (preferably under Win7).
Ip address of this image is 192.168.1.100

Cgminer setup:
SSH into the miner, user: pi + password: raspberry

edit pools according to your needs (actuall software supports only pools with static difficulty 64, for example polmine.pl, f2pool.com, and ghash.io (please don't mine on ghash!)
Ctrl+o to save, Ctrl+x to exit

Point your web browser to the miner ip address, to see it's stats



Overall feeling: miner is made really solid, it has a nice steel/aluminium design, due to high density hashratio.com managed to keep the units relatively small. Fans are more than enough to keep the miner cool.
They look and feel really neat. Next generation of hashratio.com miners should be a big success.
