Bitmain Antminer U1 – review, hands on

THELOGICALINDIAN - Bitmains new mini bitcoin miner has aloof landed in our easily at the North American Bitcoin Conference in Miami It is a rather baby and bunched bitcoin miner It can be acclimated by individuals after mining farms or it can be an ideal band-aid for appointment use Power able and bashful after admirers or any added affective genitalia it has alone a absolutely ample heatsink

Small, able and a fast another to alpha mining, it represents a acceptable alpha in the business. It can body up baby farms, and enables you to try the best accessible mining pools and cooling solutions to adapt for the big miners after on. You know, mining is consistently the adamantine way, but it has it’s own beauty.

It is a baby USB drive – sized miner, with a ample heatsink on the back. It comes with ambit of 3.0”x1.4”x0.5” (inches), belief 2.1 ounces. It is a bit added than an accustomed usb stick, so back application hubs, try to abstain accumbent ports. It is operating on 58 Centigrade Celsius, actuality a bit too hot to touch, so try captivation it on the side.

Keeping in apperception the up to date conditions, it is adamantine to appraisal the exact ROI amount for a baby miner like that. If you go for beeline profit, try some of the another coins. One important aphorism about mining is, if you are counting on the amount accession of bitcoins, don’t buy a miner, advance in the bitcoins and wait. Of course, these little pals are not the ultimate money authoritative machines, but abundant accessories to be allotment of the association and to abundance your own bitcoins.

I can brainstorm the Antminer U1-s as an accustomed bashful accessory in the aback of your appointment PC, or maybe affiliated to your home NAS or server. While the Antminer is able and accessible to use. I had some agitation with cgminer. On the added hand, with bfgminer it was accessible as a pie (you can acquisition abundant instructions below). As abundant as I was concerned, it was abundant added assisting than the antecedent models by ASICminer (333 Mh/sec, can be overclocked to 450 Mh/sec). The actual availability of the artefact is a aberration in this industry, so that was a big plus. In my opinion, I’d buy it as a amusement device, to affix it to my continuously active Raspberry Pi at home. I’m a bit anxious about the heat, so I would leave it in allegation for a few days, to see what happens.

Setup tutorial – Windows

1) Download/Install this driver: http://www.silabs.com/Support Documents/Software/CP210x_VCP_Windows.zip

2) Download bfgminer windows adaptation here:  http://bfgminer.org/

3) Unzip bfgminer files to your computer; for archetype C:/miner/

4) Create a adjustment to the bfgminer.exe file
Right bang on your desktop and accept New -> Shortcut; use the browse advantage to locate the bfgminer.exe book that you abashed earlier.

5) Right bang on the new adjustment and bang “Properties”.  In the “Target:” amend to appearance as follows (replace basin capacity with your own user):

C:\miner\bfgminer.exe -S antminer:all -o pool.url:3333 -u username -p countersign –set-device antminer:clock=x0781

6) Double bang the adjustment to alpha BFGminer and alpha mining.

Cgminer is clearly not accurate yet, try it with the zadig driver, actuality is a sample code:

c:\cgmineru1\cgminer.exe –bmsc-options 115200:20 -o degree tcp://de1.miningpool.co:10701 -u grabber.uno1 -p x –bmsc-freq 0781

With Linux (bgfminer):

Run the afterward commands to install dependents, download bfgminer antecedent and body it:

To run bfgminer use a command such as (change our audience basin user with your own user):

If you are application a Raspberry Pi do the following:

Add the afterward cipher at the end of the aboriginal band (on the aforementioned band as the added text)
