Hi,

I was mining to test the pool and I can see that one round has the status "Deposits Sent" and never changes

227479 3094 Payout not redeemed DGC Bitcoin 0.00033559 BTC 2.15% Deposits Sent No 2014-02-15 04:03:31 UTC

So I can not redeem the amount of BTC of that round.

What's the problem?

I'm using the IRC but nobody say anything.

Thanks

Is it a joke?

Where are the Litecoins I had in my account?

Why nobody said anything? I don't understand why I have to check this forum to know about the pool.

I'm really irritate now and you are telling about the great service. What service?

If I go to CoinHuntr, the username and password I had is not working so I don't know how you will know about what I had.

Before to close a site, you MUST say about it.

Bad way to make the things.

Xgtele, here the master is ckolivas but if you wanna use the erupters, change:

./configure --enable-bflsc

For

./configure --enable-icarus

I don't have any erupter but if I'm not wrong, with that should work

$800 offer. That would put the break even period at 2 months - but judging by the difficulty rise it might be 3 or 4.


Sorry allinvain but the eBay auction has a higher price than that.

you selling the dragon by chance??



I can sell you the dragon if you need it. PM sent.

Where are these custom firmwares coming from...BFL or a third party? Can they be flashed at home?

This firmware is coming from BFL, to flash the jalapeno you need special hardware and if you mistake it will be bricked.

Difficulty is set to jump up at least 15% days before the auction even ends, lol. People who bid on this with today's difficulty in mind are literally losing ROI every single day they wait. This is why it's a bad idea.

A 10-day delay when difficulty is rising still is nothing but a loss in money.

What would you take for it now? That's the good question.
[/quote]

I know but usually people is checking eBay on weekend so it's a 10 days auction. I wanted to use the option "Buy it now", but I couldn't use it.

If a person make a good offer, I can send it immediately.

Dead link..

Try again, the link is working

Time left: 9d 20h ... LOL
Why are u posting this on forum ?

Why not? I'm selling the jalapeno so I'm posting it here, this is the marketplace.

What the fuck?
Thats way more expensive than at BLF itself, and firmware is there to be updates, not to pay another 800$...

Have you seen what's the price I started to sell the jalapeno? 100$ what is less than at BFL.

What the fuck?
Thats way more expensive than at BLF itself, and firmware is there to be updates, not to pay another 800$...
You have no clue, so refrain from making comments like this in the future. Just for your own sake that is.

The price as it is now on ebay is about right. Flashing the firmware is not a simple update, you need special hardware to do that.

Thanks, that's true, to flash the jalapeno you need special hardware and if you mistake is possible to brick the jalapeno.

Time left: 9d 20h ... LOL
Why are u posting this on forum ?

I'm wondering why it's listed with a 10 day delay as well... if I bought one, I would want it within a couple days; there's no way I would offer up money NOW so he can mine with it for another 10-13 days before sending it out. That's asinine.

Why not? This jalapeno was ordered more than one year ago so if you want it in a couple of days, you can make an offer and I will send it to you today if you want.

ebay links should not be allowed on this forum no more, u either sell here, or ebay

Why not? This is the marketplace and I'm selling on eBay so I don't know what's the problem.

Q: On linux I can see the /dev/ttyUSB* devices for my Icarus FPGAs, but
cgminer can't mine on them

A: Make sure you have the required priviledges to access the /dev/ttyUSB* devices:

 sudo ls -las /dev/ttyUSB*
will give output like:
 0 crw-rw---- 1 root dialout 188, 0 2012-09-11 13:49 /dev/ttyUSB0

This means your account must have the group 'dialout' or root privileges

To permanently give your account the 'dialout' group:
 sudo usermod -G dialout -a `whoami`
Then logout and back in again


If you are using an Icarus FPGA, don't forget to configure CGMiner (Step 10 of the tutorial) with:   ./configure --enable-icarus



i personally prefer not using the gui. its a system hog

using "screen" command in console allows me to access the bfgminer thats running behind the scenes without stopping anything.

and cacti allows me to see charts via web Cheesy

Can you explain the steps? Would be nice if I can try that.

Awesome job, thank you.
My RaspberryPi is already configured and waiting for its ASIC to come...

One small suggestion - to make the guide even more clear you could add two initial steps of SD card formatting and saving the image file to it.


You can find that information here:

http://elinux.org/RPi_Easy_SD_Card_Setup

So I think that's not necessary.

I'm waiting an ASIC too.

Super Tutorial Raspberry Pi+Raspbian+CGMiner+TightVNC+WIFI at boot

Hi, I'm gonna make a super tutorial to make an automatic miner using a Raspberry Pi and a USB ASIC, in my case I'm gonna make the tutorial for a Butterfly Labs ASIC, but will be almost the same for other kind of USB devices.

When you finish the tutorial, the Raspberry Pi and the ASIC will mine in automatic mode, will be plug and mine, if you have a power outage don't worry and if something goes wrong, unplug, plug and ready.

Before to start the tutorial, is important to know the Raspberry Pi IP and to give an static IP, the best way is with your router.


Possible software we need:

- Raspbian, OS .img file (http://downloads.raspberrypi.org/images/raspbian/2013-05-25-wheezy-raspbian/2013-05-25-wheezy-raspbian.zip)

- SD Formatter, to format the SD (https://www.sdcard.org/downloads/formatter_4/)

- Win32imager, to copy the .img file to the SD (http://sourceforge.net/projects/win32diskimager/)

- Putty, SSH client to connect to the Raspberry Pi (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html?)

- TightVNC, client to connect to the Raspberry Pi desktop (http://www.tightvnc.com/download.php)


Tutorial steps

1- Open Putty or any other SSH client and write the Raspberry Pi IP.

2- You will get a security alert, don't worry, say "Yes".

3- Login as: pi

4- Password: raspberry

5- The first thing to do is to change the default username and password:
   - sudo adduser "youruser" --force-badname (without quotation marks)
   - Will ask for the password for that new user two times and other data
   - To give permissions to the new user: sudo visudo
   - Will open the file sudoers.tmp
   - Under the line: root ALL=(ALL:ALL) ALL add: "youruser" ALL=(ALL:ALL) ALL (without quotation marks)
   - At the last line change: pi ALL=(ALL) NOPASSWD: ALL for: "youruser" ALL=(ALL) NOPASSWD: ALL (without quotation marks)
   - CTRL+X to exit, Y to save followed by enter
   - Now we can use sudo with the new user, to check it, use: su "youruser" (without quotation marks) to change to the new user, then: sudo raspi-config, if you can open the configuration tool, the new user is ok, close the configuration tool.
   - Reboot using: sudo reboot
   - Login with the new user
   - Now we are going to erase the user "pi" and the files of this user with the command: sudo deluser --remove-all-files pi
   - Now we have our user ready and the user "pi" doesnt' exist.

6- The next is to update the system with these steps:
   - sudo aptitude update and wait until finish
   - sudo aptitude upgrade Will ask "Do you want to continue?", "Y" to say Yes and wait until finish again
   - Reboot using: sudo reboot

7- The next is to set a few things with the Configuration Tool with these steps:
   - To open the configuration too: sudo raspi-config
              - Activate "Expand Filesystem" to use all the SD card
   - "Internationalisation Options" to change the language, timezone and keyboard layout
   - "Advanced Options"-"Hostname" to set the visible name of the Raspberry Pi on the network.
   - Reboot using: sudo reboot

8- The next is to activate the Wifi network
   - To check if the Raspberry Pi is detecting the USB dongle, use the command: sudo lsusb You should see something similar to this "Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter" but will change depending of the model you connect.
   - Now we need to install the tool to set the wifi parameters using: sudo aptitude install wicd-curses Will ask "Do you want to continue?", "Y" to say Yes and wait until a blue screen, press space to select and enter to add your user to the netdev group and wait until finish
   - To open the tool, use the command: sudo wicd-curses
   - Move the cursor to your wifi network
   - Shift+P to go to Prefs
   - Check "Wireless interface", if it’s empty, write "wlan0" (Without quotation marks)
   - Press F10
   - Shift+R to refresh and see your wifi if you had to write "wlan0"
   - Move the cursor to your wifi
   - Right arrow to go to config
   - You can set here a static IP, but I prefer to set the static IP in my router
   - Activate Automatically connect to this network
   - Key: (write the wifi password)
   - Press F10
   - Shift+C to connect and if you obtain an IP everything is working fine, here, you will lose the connection, use the new IP for the wifi connection and connect with Putty again.
   - Login
   - Shift+Q to quit
   - Turn off using: sudo halt
   - Disconnect the ethernet cable and turn on the Raspberry Pi again, from now should work with wifi
   - From now, connect to the Raspberry Pi using the new Wifi IP

9- Now we are going to install TightVNC
   - Use the command: sudo aptitude install tightvncserver Will ask "Do you want to continue?", "Y" to say Yes and wait until finish
   - To start TightVNC use: tightvncserver
   - Will ask for a password to connect to the remote desktop, it can be different to the Raspberry Pi password, write the password two times
   - Wil ask "Would you like to enter a view-only password?",  "N" to say NO to have a total control of the remote desktop.
   - To autostart TightVNC every time we turn on the Raspberry Pi, we have to edit the file rc.local, using the command: sudo nano /etc/rc.local
   - Now, before the line "exit 0" add the line: sudo -u "youruser" /usr/bin/vncserver :0 -geometry 1280x800 -depth 16 -dpi 100 (The user is without quotation marks, "geometry" is to set the resolution of your screen, "depth" is to set the color depth and "dpi" is to set the font size) so adjust these parameters to your needs.
   - CTRL+X to exit, Y to save followed by enter

10- The last step is to install the miner, CGMiner seems to work very well with the Raspberry Pi so these are the steps:
   - Before to install CGMiner we need to install this dependencies: sudo aptitude install git autoconf libtool libcurl4-openssl-dev libncurses5-dev pkg-config yasm make libusb-1.0-0-dev Will ask "Do you want to continue?", "Y" to say Yes and wait until finish.
   - Now we can start installing CGMiner:
      - git clone git://github.com/ckolivas/cgminer.git cgminer
       - cd cgminer
       - ./autogen.sh
       - export LIBCURL_CFLAGS='-I/usr/include/curl'
       - export LIBCURL_LIBS='-L/usr/lib -lcurl'
       - ./configure --enable-bflsc
       - make
       - sudo make install
   - The last step is to autostart CGMiner every time we turn on the Raspberry Pi:
      -We need to edit autostart with this command: sudo nano /etc/xdg/lxsession/LXDE/autostart
      -At the end add the line: @/usr/bin/lxterminal --geometry=90x35 -e cgminer (The parameter "geometry" is to set the size of CGMiner, so adjust the parameter to your needs)
      -Reboot using: sudo reboot

11- Install TightVNC on your computer
   - Write your Raspberry Pi IP
   - Will ask for the password of TightVNC
   - If everything is ok, you will see the Raspberry Pi desktop and CGMiner open waiting for the server details.
   - Write the URL
   - Write the username
   - Write the password
   - Now will start to mine, but we need to save the configuration file:
      - "S" to go to settings
      - "W" to write the config file
      - "Enter" to save the default "cgminer.conf"
      - "Space" to clean the screen

12- Now everything will work automatic
   - If you need to stop CGMiner, use que key "q"
   - If you need to reboot the Raspberry Pi, use: sudo reboot
   - If you need to turn off the Raspberry Pi, use: sudo halt
   - If you need to modify the config file "bfgminer.conf", open the "File Manager", "View"-"Show Hidden" and click to your user, you will see a folder ".cgminer", and inside you have the file, don't mistake with the folder without "dot".
