Do you prefer blonds or brunettes?  Redheads are extra.

Well since the bitcoin hit 1000 it's been a little crazy. Check out the amazon prices:

Here's ebay listing:

Im just looking at current market value.  

Fair question.

USB Miners are going for about 70-80 dollars each now on amazon and ebay.  So 20 of them at 70 bucks is 1400.  20 port USB hub is around 200 dollars in itself.  Rasberry PI usually goes for around 50-90 on ebay.  But I've already pre-configured it and did all the hard work.  It's literally a plug and play operation.

Selling some gear for holiday money.

This auction has everything you need to get started:

- Rasberry Pi Model B 512MB RAM unit
- 5V 1A (1000mA) USB port power supply for Rasberry PI.
- USB cable - A/Micro for Rasberry PI.

- 20 Port USB 2.0 Hub
- 2 USB 2.0 Cables for HUB
- Power Supply For Hub
- 20 ASIC USB Eruptor Miners running at 333mhz (6.5 gh/s total).

Details:

20 ASIC USB Erupter Miner running at 333mhz:

These are ASICMINER USB BLOCK ERUPTOR. This USB devices mines Bitcoin at a ESTIMATED ~333 MHash while using only USB spec power (0.5 Volt, approximately 2.55 Watt).

It has significant improvements in:

   * Heat reduction: 500-510mA (sapphire).
      * Stability: I ran them for two months. No hardware errors.
      * Speed: 333+MH/s.

Appearance:

   * SMT machine assembly (sapphire).
         * Heat-sink front-case 2-in-1 logo-ed (sapphire).
*  LED added.

20 port USB 2.0 HUB designed for Bitcoin mining:

This hub accommodates up to 20 high power devices simultaneously, and uses only two USB ports on your computer or external hub. Each port supplies up to 750mA. This makes it the ideal device for large numbers of ASICMiner Block Erupter USB’s. You can easily build a 6.7 GH/s ASIC mining system with these hubs.

Rasberry PI Model B 512MB RAM:
The Raspberry Pi® is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 512 Megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems. This  Raspberry Pi Model B 512MB RAM model has two USB ports and a 10/100 Ethernet controller.

The Rasberry PI comes with a SD card loaded with Minepeon software on it that is configured for Bitcoin mining.  All you need to do is boot it up and connect to the web server on it to configure it.  Super simple!

I’ll also pre-configure it for you if you already signed up with a Mining Pool (I recommend  Slush’s Pool  )

Note:  Since the USB miners do tend to get a little hot, I would run a fan on the rig to keep things cool!

NO INTERNATIONAL SHIPPING.  USA ONLY!

Wished I lived in your area.  Would love to pay for flight school with bit coins.  I hope more businesses start accepting them.  It'll help the currency.

Great tutorial how to set it up on a mac.

I found out about it from a couple security forums I read.  Being a techy geek it sounded like fun to build a machine to mine coins.  So got into it because of that.  Got a nice 14 Ghps machine so far.

I have three anker 10 port USB 3.0 hubs.  The rest are on roswill hubs and a d-link one.  Those hubs are half the ports used since power is less.  Hopefully with the 20 port hub arriving today I'll re-organize the rig and move it to the basement utility closet where it cooler and the internet comes into the house. 

Currently I have 45 ASIC USB miners attached.  I have a pretty big fan on all the units keeping them cool.

I did get a 20 port hub recently so I'll move some to it and I also got about 4 usb fans to try to keep things cooler.

Thanks for the information guys.

Can someone tell what would cause reject rate to be over 1%?  The last couple of days, the reject rate has been usually around 0.15% or less.  But today it's just a little over 1%.  Is it something I should worry about?

I'm new to the bit coin scene and enjoy the geek aspect of it.  I started by getting raspberry pi and programming it to work nicely.  Got about 35 USB eruptors running on some anker hubs.  I love building and programming the gear to work nicely.  Right now I have it running at around 10ghash but looking to get it up to 20 soon.  Looking at building some shelving to put all the gear on.

But overall, I love making things work and if it makes a profit someday, it'll be a bonus.
