The Dragon miner Made in China
Basic parameters:
The semiconductor process
Hardware is ASIC chip, the power of single chip is 20G-35GH/S.
Low power consumption mode :1TH/s Hash computing power
Keep good balance between the computing power and power consumption.
Chip consumed power:640W(1TH/S power,low power consumption mode)
The whole miner power on the wall:884W.
 External power supply:110-230v,50/60HZ ac power.
Under the condition of 19“rack installation,5U highly.
Can be placed on the ordinary work bench, the environment temperature is 25℃
Custom Linux .

appearance and workmanship
The shape of Dragon miner as shown in figure1。
Size:48*31*35 cm;
Total weight:21KG.

   The group photo of Dragon miner and Ant miner,as shown in figure2.

Picture2:one Dragon and a little Ant

2、the internal structure
    Unscrewed the screw on the top of the miner, turning up the case cover, you can see internal structure of the miner.The miner is divided by a piece of organic glass into two layers,which makes the downside cooling ventilation. The upside for the two power supply, the Great Wall with 1000w power supply. Late overclocking need buyer to add a 600w power.

Control panel is the center for accessories which connected module,power supply,fan and raspberry pie.This sample control panel has six module interface, currently only access five groups, and one group is empty.The Control panel as shown in picture4.

  The raspberry pie as shown in picture5.To update the program or overclocking operation, must change the contents of the SD. SD card backup can take down into IMG, can also upgrade the program by download the latest IMG. Specific operation, this website will open another talking stick to the operation of the raspberry.

 The data of miner runing:

1、the average computing power
After nearly 30 hours running operation, we observed the highest computing power on the 1.3 T, lowest 0.96 T, look from the computing power curve, fluctuates around 1.05 T central axis.

Picture8:the computing power curve

Random sampling an average speed of 20 minutes,as shown in picture9.

Picture9:average speed of 20 minutes

2、24 hours of earnings
24 hours due to the need of test and moving, accumulated nearly an hour of 24 hours downtime earnings figure is shown in figure 10. If you don't stop, 0.16 BTC should be steady.
http://img03.taobaocdn.com/imgextra/i3/724488319/T2m1_tXqXXXXXXXXXX_!!724488319.jpg   
Picture10:24 hours of earnings

Based on past experience, the miner run BTCG pool, according to the difficulty of the current (February 24, 2014) revenue into 0.18 BTC per day.

3、The power consumption of the wall
The power consumption on the wall is the actual consumption of electricity , the sample miner test of the power consumption on the wall is fluctuating 880 w up and down.

Je ne comprendrai jamais.... pourquoi les gens capables de fabriquer de tels miners les vendent au lieu de les utiliser eux-mêmes, si miner était si rentable. Il les auraient plus rapidement, avant que la difficulté ne les rendent obsolètes...

Perso, je pense que quand tu en achètes un, ils le produisent assez rapidement, te disent un temps avant d'attente avant expédition, puis pendant ce temps ils minent un peu avec et après, quand tu te rapproches de la date, ils te l'envoient et bien sûr, la difficulté a bien monté donc ça n'est plus si profitable  Grin


Enfin moi je trouve ça tout à fait logique

Pour trois raisons essentielles:
1- Le montant de l'investissement ne se paient pas en bitcoin (les usines n'acceptent pas de bitcoins mais de la monnaie fiat) et il faut payer tout de suite.
2- La vente de mineurs est beaucoup plus rentable que le minage: tu investis 1000, tu gagnes 2000. Tout de suite.
3- "un tiens vaut mieux que deux, tu l'auras"
