Hi,

Did you contact the Pi-Juice team for your project?

Hi again

Perhaps, some of you, like me, would like to know (if they don't already ): What are bitcoin miners really solving?

here is a nice and interesting explanation:
http://bitcoin.stackexchange.com/questions/8031/what-are-bitcoin-miners-really-solving

Jeff.

Hello everybody

New out of the box, my compac worked great at the usual frequency: 150Mhz (although i didn't get rich  ). Just to have fun and to see what would happend i set the frequency at 250Mhz. The hashrate increased significantly: more than 33Gh/s. However, i started to get HW errors: no valid hashes in the last 10 seconds...I thought i could just adjust the voltage using the small potentiometer on the compac, but i decided not to do it (or more precisely to do it later). However, these last days i noticed than even at the normal frequency: 150Mhz i still get many HW errors. Considering i didn't change anything, i'm puzzled...

Any ideas?

Thanks,

Jeff.

I wish you good luck and every success in sloving the block. That beeing said i still have a question though:
why do you need to join a pool for solo mining

Regarding the nuclear plant you are talking about. Yes, F. Hollande said the governement will close it (but
it was during a meeting for the election compain and here in France nobody believe/have trust in our
leaders and politicians. They often don't keep their promise

Regards,

Jeff.

Hello zOU,

I got two 333Mhs ASIC Block Erupter. In fact just one at the moment because i lend the other one to
a friend and he didn't give it back to me. I got them from camolist for free because i bought a coin
from him. I can give the BE to you. That beeing said, why are you interested in these pathetic miners?
i mean they are nearly as expensive as a compac and much less powerful.

Cheers,

Jeff.

What do you plan to buy?

Regarding the compac: there is a white led blinking next to the green led, i guess it tells
that the miner is working, but more precisely what does it mean? Does it indicate that a
calculation has successufully been done?

Cheers,

Jeff.

Yes indeed 


Great

Thanks a lot. I understand better. Btw, do you manage to make some profit? Taking into account the price of the hardware and the electricity price, it looks as it has became quite difficult...Perhaps i should have begun 3 or 4 years earlier, it might have been easier...

Cheers,

Jeff.

This is indeed what i understood. Btw, is my calculation correct? I mean it sounds weired that
an average worker in that pool owns miners that are as powerful than 207 compacs...

Cheers,

Jeff.

Hello Mercado

According to the graph, i think i got three (tiny) btc payments. The first two beeing when using the 330Mh/s ASIC block erupter.
That makes sense because the last one (when using the compac which is 25 times more powerful) were much higher. So i think i did get a payment with the compac. Did i misunderstand something?

Cheers,

Jeff.

Guten Abend

Thanks for the informations. What's the amount of the reward? BTC25 ?
Btw, did you already manage to solve a block? I mean it must be quite hard...

Jeff.

Hello zOU,

Thanks for your explanation. So, if i understand correctly:

1) When i get no earning for my contribution, it does mean that anyone in that pool get a reward.
2) When i get something, then i does mean that 25 has been shared between the members
of the pool. If anyone had the same miner hardware as mine, it would mean that there are 25/0.00000637=3 924 646
members in that pool. On the other hand i read that there are in fact 'only' 18 901 active workers. Does
it mean that an average worker in that pool owns miners that are 3 924 646/18 901=207 times
more powerful than mine?

Cheers,

Jeff.

Hello everyone:)

I got my compac in the post yesterday, and of course i wanted to test it at once  

I launched the the gekko cgminer software:
./cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u Jeff_59.worker1 --compac-freq 150
The miner seemed to work great, however i'm a bit puzzled. Indeed, i looks as if i still don't earn
anything

I mean nearly each time the task is confirmed i get no rewards

Did i make something wrong, or does it simply tell me that mining with one compac is not enough?

Regards,

Jeff.

Hi,

Thanks for the information


Have you ever tried to join Sidehack pool or ckpool? It looks as if there is a waiting list to join
these clubs. Also do the compacs have to be bought from Sidehack to have the
permission to join its pool?

Cheers,

Jeff.

Ok, thanks for the information

Hello,


Do you plan to plug the 6 (4+2) gekko compacs on this HUB?

As far as i'm concerned, i ordered the D-link HUB:
http://www.amazon.fr/D-Link-DUB-H7-ports-pour-Noir/dp/B0000B0DL7

I will test and report its ability to support the compacs. Do you think that
pluging HUB on HUB to support more compacs is a good idea?

Cheers,

Jeff.

Hello,

Thanks for your message.


Here what i got:

pi@raspberrypi ~ $ cd /home/pi/Desktop/cgminer-gekko
pi@raspberrypi ~/Desktop/cgminer-gekko $ ./cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u Jeff_59.worker1 --icarus-options 115200:1:1
 [2015-11-02 09:10:14.284] ./cgminer: --icarus-options: unrecognized option                   
pi@raspberrypi ~/Desktop/cgminer-gekko $

Although it worked fine with the "official" cgminer v.4.9.1

I'm puzzled because i think i compiled the gekko cgminer with the option --enable-icarus --enable-gekko

Regards,

Jeff.

Hello


I hope there will still some left when i place my next order . The first order beeing just a test.



Thanks. I didn't forget to specify --enable-icarus to create the binary file, but had no idea of
the options i have to specify when launching cgminer. What does this option suppose to do?

Btw which pool did you decide to join?

Have fun with your miners

Jeff.

Hello,

Thanks for the informations.


I compiled the source files too and didn't had any troubles on the Raspberry Pi. However i noticed that a cgminer binary file is already existing in the folder downloaded, so the compilation may not be madatory, although it is probably better to do so since the binary file is "hardware optimized" that way.


Lucky you Their oversea shipping costs are, in my opinion, quite high (more or less the price of a compac itself...). I prefered to have the compac shipped within the USA, and reshipped back to me in France (thanks to the forwarding company i currently use). If i remember well, i paid (taking into account both shipping charges) less than $7. That being said, my compac is still in transit

Btw, did you have to pay customs duty?

Still, i went a ahead and tested the cgminer-gecko software on my 330MH/s ASIC block erupter.

./cgminer -o stratum+tcp://stratum.bitcoin.cz:3334 -u Jeff_59.worker1 --?

[I didn't know which frequency paramater i should specified, so i didn't specify any ]

Although it seemed to work, the tasks given by the software were too difficult for this miner. In fact, the miner were just warm and not hot as it used to be when using the "regular" cgminer software...It didn't manage to mine anything...

Cheers,

Jeff.

Thanks a lot for your quick answer notlist3d 


Ok, so i think i won't need Minera. I'm going to compile the cgminer source from Novak this afternoon (even if i don't have the compac in hand yet).

Cheers,

Jeff.
