Look how much the Unknown slice has grown. It used to be tiny. Difficulty going up another 6%. It would appear there are huge private setups running.

Yeah, it is this kind of industrial mining that finally drives me away from BTC  Angry

Having home miners was one part of BTC that I enjoyed. All over for months now. The other part was being part of a new and more democratic way of payment. That was probably naive but I nonetheless did appreciate it. For a while now bitcoin just feels like greedy mafia business and third world money making machine. For the mafia part: not only do asic producers try to rip you off but also cloud miners and payment exchanges. And for the third world: throw coal in on the one side and feed btc miners on the other side; let's not talk about ecological consequences.

From my GPU times till now bitcoin has turned from hobbiest enjoying themselves into a twisted Lovecraft version modern currencies. Two years ago I would encourage people to try bitcoins, try mining and try being part of the community. But nowadays I would say stay away. There is nothing (positive) to experience anymore. Rip off and industrial mining await you  Undecided I mean I actually think it is fair to pay a few percentage points when using paypal and not having to deal with all that bitcoin hassle.

I think now is time for me to also turn off my bitcoin node I've been running since my miners were turned off. It just makes no sense to give anything back anymore.  Cry

What do you mean? From what I read on their website those miners are supposed to ship at the 10th. Did they say something about not delivering it?

Shame it is so loud.

I wish they would offer a quieter version more suitable for home miners. I mean I would be willing to pay 20-50 usd on top if I could run it at home.

I ordered a DICE from technobit to replace my power-hungry S1 I have been using for a while now.

I think home miners quitting the mining business also has effects on the bitcoin economy as a whole. In the 2013 BTC boom hardware was solely bought with BTC, fuelling the rising prices of BTC. In 2013 und 2014 I spent most of my BTC at buying hardware. After my miners were obsolete in spring last year I did not need additional BTC. So I kept my BTC except some humblebundle purchases. So loosing the home miners is not a good prospect for bitcoin.

I'm just setting up some nodes to help the network.

Thinking of doing the same because my miner runs only occasionally for (gamble) solo mining.

That's how I do it. I start my old S1 a few times a week for a few hours and have it pointed to a solo polo. Just testing my luck and enjoy the humming of my S1. I am long out of the mining game but I like this cheap form of gambling.

I learned the hard way that buying BTC is much cheaper for me than buying miner, psu, raspi's and pay for electricity (and time invested doing setup or maintenance).

Re: [ANN] Technobit HEX16A2 - 16 chip Avalon Gen2 board

Just for your information, when technobit send their first batch of HEX16A, my board stuck on speedy office for more than 3 week because marto issue full prices invoice. Speedy demand marto to issue low prices invoices(Proforma Invoices).
The 10 USD per board is my suggestion  Cool

My second order HEX16C use UPS as carrier & i didn't find any invoices but marto declares the miner as SAMPLES Grin And again no import tax  Cool
Since the miner come with no case, then there is no problem declaring it as SAMPLES(which should be free)  Cheesy

Low prices = No import TAX = Quick custom clear

As I said German customs can be really tough. Recently I had a case where I had to get to the tax office and prove to them that usb miners were worth what was on the import tax statement. I could not prove it because it was rediculous low. So I had to pay important taxes plus 100+ euro fine for cheating on import tax.

I just want to share some images of the miners that just arrived. I got two packages because I ordered 3 miner at first and two days later decided to get another one.

Package is tight and secure on the outside:

The inside also looks tight an secure:

I am glad customs did not look at this. USD 9.20 is way too low ... in Germany you have to pay about 100-150 eur if you cheat at customs and get caught.

That's how they look. Thank god they all have molex.

Done my homework and went on a shopping spree. That's what is needed to get them working quietly

I have a question for the users who have already gotten their products:
how long does it take until you got your trackingcode for DPD-website.
Once the status has changed to Shipped?

I got my tracking code immediately after I received the shipping email. The tracking code worked fine; I just googled for "dpd speedy tracking". But it says on the speedy site that tracking information may not be up to date.

It's http://www.protact.net/shop/usb-miner/12/red-fury-usb-bitcoin-miner?c=15. I has VAT included. So if you like me do not live in Germany it is 54,54 Euro per Red Fury if you take 3 or more. You can contact them via Mail info@protact.net because in their shop there is no option to switch to English.

I bought all but one Red Fury miner from them. Far better service than buyahash or technobit.

Against my better judgment. . .

Just spent 0.5 BTC on another 5 Red Fury ASICs. With my current 3, this should give me about 17.6 GH/s total.

You could pencil-mod them. I have 10 Red Fury's and with pencil-mod they run 2.8-3.1 gh/s.

Just one more thing. Red Furys are really cheap and overclock quite nice to stable 3ghs. I run 14 red furies (2.9 - 3.1 ghs) and bought them for about 80 euro a piece. Current prices for red furies are 65 euro in a shop in Germany.

Will you make money on them? Probably not. But if you like to get into mining buy a stick or two and keep the network going.

I do not seem to get it right. I did:

wget https://github.com/ckolivas/cgminer/archive/v3.11.0.tar.gz
tar xfz v3.11.0.tar.gz
cd cgminer-3.11.0/
wget https://www.dropbox.com/s/t1rgvsvd6qxjga5/b535bc08267aef90511afff23cb9ec48c4a6a704.patch
patch -p1 < b535bc08267aef90511afff23cb9ec48c4a6a704.patch
./autogen.sh --enable-avalon --enable-hexminerc
sudo make install

But I get this error when doing make install:

...
gminer-driver-hexminerc.o: In function `hexminerc_send_tasks':
/home/pi/cgminer-3.11.0/driver-hexminerc.c:174: undefined reference to `SHA256_K'
collect2: ld returned 1 exit status
make[1]: *** [cgminer] Error 1
make[1]: Leaving directory `/home/pi/cgminer-3.11.0'
make: *** [install-recursive] Error 1

Any ideas?
Use following command:

Code:
./autogen.sh --enable-hexminera --enable-hexminerc

Got it sorted out.

libhexc.c had to be patched too. This blog entry helped me to get on the right track: http://www.cberendt.de/2014/01/technobit-asics-with-cgminer-raspbian/

Contacted buyer.. Our system showed that he ordered an item that was backordered at the time, thus why we didn't ship to him. We're sending it out via EMS so he gets it in about 3 days.

Indeed ... thanks a lot!
