Im looking for exactly the other side. ;-)

Can somebody provide a picture of the block erupter stick with its heatsink removed? Thanks in advance!

A friend of mine has invested in Havelocks ASIC-Miner Fund. Hes getting dividends and the fund is rising in worth. Today I also hopped in with a little amount. They claim an annual yield at 63.79%. Sounds good.

I dont think active cooling is neccessary. I got three Erupters and I found out that a passive chipset-cooler attached to the initial cooler along with this thermal-pad does a great job. Got a picture from my setup here:



Soon each Erupter will get bis own chipset cooler.

Thanks.

Is it actually possible to reprogram the Block Erupter USB-Sticks to perform another task... lets say video encoding?

One cannot compare my situation to lets say yours if you bought all the stuff right now. That is because my setup has originally not been build to mine bitcoins but to power my computer and several other things like router, TFT and so on.

Also I did not buy a complete new battery. I bought a used one with 100Ah capacity for just € 20 from a friend oft mine. Furthermore if you compare the power consumption for lets say one Raspberry, a powered USB-hub and say four Block Erupters, you end up with something like 20W. My setup has been build for about 100W load at about 3 hours a day.

If you really want to run this for pure profit, you should maybe stay away - at least in man scenarios.

Yes, you can use this on your balcony.
In fact, I am using my solar-island on my windowsill (behind the windows!) because I dont even have a balcony. I am loosing around 40% efficiency that way. But its still working like a champ.

Hi to everyone.

In this post I will share my knowledge about building a solar power island like the one I build myself to power my computer and router. Of course everything you are about to learn from this guide can be used to set up a raspberry-pi-driven mining-plattform thats brings mining for essentially free (of course: assuming you got enough sunlight.)

I. Hardware

  Silver: 1x Varta Dynamic Blue 60Ah (€ 72.00)
  Bronze: 1x Phaeton 20Ah (€ 47.50)
  
  
• General accessories (You will need this regardless which setup you chose)
  

  ---

  1x Profiline solar power cable 3m (€ 22.90) (Thats the one, I am using.)
  1x Battery connection cable with fuse-clip (€ 27.90) (Thats the one, I am using.)
  1x Autek 12V to 5V/3A USB-Converter (€ 9.47)
  
  
• Optional accessories
  

  ---

  1x Raspberry Pi (Kit with cables, card and stuff) (€ 59.99)
  
  
• Accessories for powering an ATX-Mainboard
  

  ---

  1x PicoPSU 12V/90W (€ 32.95)
  1x PicoPSU 12V/160W (€ 45.95) (Thats the one, I am using.)
  1x M3-ATX 6-24V/125W (€ 52.95)
  

II. Setup

• Step 1: Make sure you get the most efficiency out of your solar panel.
  

  ---

  Use the following chart to find out the best setup:
  "Dachausrichtung" means roof orientation.
  "Dachneigung" means roof pitch.
  
  
  
  
• Step 2: Connect solar panels, solar charge controller, battery and USB-Power-Output
  

  ---

  2.1: Always take care of correct polarity.
  2.2: Connect the solar panels positive pole with the controllers positive solar-panel-jack and then connect the negatives.
  2.3: Connect the batteries positive pole with the controllers positive battery-jack and then connect the negatives.
  2.4: Connect the Autek-12V-to-5V/3A-USB-Converters positive pole with the controllers positive load-output-jack and then connect the negatives.
  
  
• Step 3: Connect your Raspberry Pi along with your ZTEX/Cairnsmore/whatever-you-may-want-to-use
  

  ---

  Congratulations! You are now mining bitcoins using free sunlight. Consider yourself being a champion.

III. Useful links and tools

• ---

  Calculation of Voltage/Current/powerconsumption and battery capacity.
• A Google-Maps-Overlay for the roof orientation.
• An android-based compass-app.
• "Minepeon" - The lovely piece of software, that makes a raspberry mine bitcoins.

IV. Comments

• ---

  One can of course also interconnect multiple batteries in parallel to increase the capacity. Is possible, for example, the use of used truck or particularly hot: Forklift batteries such as this one.
• In principle both, direct current and alternating current devices can be operated with such an investment. However, if you want to run AC appliances, this requires an inverter. These are available in cheap and expensive. Attention: The inverters output side provides either true sine wave or only a rectangle "wave". Rectangle wave voltage can permanently damage electronic circuit boards. The difference between rectangle wave and sine wave voltage is as follows:

Hallo,

Ich würde gerne 150 bis 200 Euro gegen Litecoins tauschen.
Gegebenenfalls biete ich auch Bitcoins im Tausch gegen Litecoins.
Komme aus Nähe Düsseldorf, NRW.

Ich bitte um entsprechende Kontaktaufnahme. :-)

It does not work with windows, or does it? 


Ahm, how do i calculate this?
My client shows the number of confirmations, the date, the 0.05BTC a description. What now? 

Good to know. Thank you!

And how long does this normaly take?

I have set up another computer and so a second wallet just to play around a little. Now on the second wallet I mined 0.05 BTC and I wanted to transfert them to my primary wallet. The clients says I need to pay a transaction fee. But I heard, that its possible to transfer BTC *without* paying a fee. How does that work? 

This looks great. Wouldnt it be possible to run this with passive cooler?
Whats the price going to be?

Well to be honest, my machine runs with no case and I have pretty good airflow in the room.
Its like this: [window] ... [computer] ... [window] (with like 5 meters from window to window.
The windows are slightly open so airflow is given.
Also the card is freshly bought. Therefore there is no dust on it.
I strongly recommend cleaning up your card. On a friends card I won 14°C by just cleaning it.
Bye the way: I had to go down to 945 Mhz cause it freezed after some hours.

Naw, It says I dont have permission to do so.

Could somebody please update this:
https://en.bitcoin.it/wiki/Mining_hardware_comparison

with the following stats I am getting on my setup:

130 MHash/s
62°C at 60% Fan Speed
phoenix.exe -k phatk2 VECTORS BFI_INT FASTLOOP=false worksize=128 AGGRESSION=10

GPU overclocked from 800 to 950
I tried to setup 300 MHz with Sapphire TRIXX but for some reason it wont go down - stays at 1.000 Mhz.

thx.

Im wondering what performance an Itanium would deliver.
Are there any miners working on that plattform yet?

Und, hat das Treffen stattgefunden? Wie wars denn so?
