Out of curiosity, does anyone know the id of the transaction of 10000BTC that was used to buy these pizzas 5 years ago?

BEUSB@6 has clawed its way back into valid range.
Phew.

I only changed 1 thing: switched to a different block erupter.  This one has a better heat sink or is just overall faster.

I was going to try to switch to mining on my windows pc but couldn't find a cgminer executable that was compiled with the ability to run block erupters.

Just to satisfy everyone's curiosity, the cgminer running on my RPI, was compiled with the icarus support and without the specific asicminer block erupter support.  (adding the blockerupter support allows it to mine for about a minute then error out and give up on accessing the blockerupter devices again)
Then I launch the newly compiled cgminer with no command line switches and just enter the mining pool server, username, and password and let it go.

cgminer 4.9.1 on a raspberry pi2

Built from commit # 57de2cc.  The newer commits wouldn't build for me at the time (Mar 7).

BTCdig seems to be claiming my hashrate is a little low; slightly in range for this lottery.  currently 207 hourly.  I started mining about 2 minutes before the official start of the contest, so it doesn't leave much room for mining to be down for any reason (internet going down, cat pulling on a usb cable, etc)

I feel silly, I verified the OP message/BTC address and left that in my clipboard and pasted it into the PM requesting entry into this contest.  Asking payment to go back to TheRealSteve.

TheRealSteve, I got both of your replies, thanks for the speedy reply.

Everyone can laugh at me.

My 0.5's that I picked up from the post office today were funded a few minutes ago.   Grin

Finally got my Erupters today, thanks Arklan


Hashing away  Smiley


I see a Raspberry Pi in the background with a heatsink attached, 5 USB blockerupters, a basic stamp 2, a dangerous looking power supply (maybe dangerous only if you have young kids or pets in the room), and some device with a big fan on it that I can't identify.

From my own personal experience:
7 port USB hub D-Link DUB-H7 worked just fine for me powering simultaneously not only 4 USB ASICminer Block Erupters but also the raspberry pi.  It has a 3A power supply and 2 1A USB charging output ports.
I'm not sure how many more than 4 block erupters it can handle; I assume by its 3A power supply it can handle a maximum of 6.

They will show up as /dev/ttyUSBx. No need to install a driver, the USB2Serial driver is preinstalled on a rpi. Smiley
Thanks.

My local mail courier didn't bother to ring the doorbell today and it is for a package that I need to sign for.  So he left a card in my mailbox telling me I can go to the postoffice tomorrow to pick it up.   Undecided

A question for those of you running these block erupters on their raspberry pi:
Where in /dev/ do you find these?  Is it /dev/ttyUSB1 or /dev/bus/usb/ or somewhere like that?  Does some driver need to be installed for them to show up?  I plan on trying to use bfgminer first with the -S all option.

There is an article on Reddit about these USB Block Erupters begin sold on eBay.
USB Bitcoin Miners are going right now for as high as $800 on eBay...
13  Bitcoin / Group buys / Re: ASICMiner Block Erupter USB group buy (US/Canada) on: May 29, 2013, 06:21:26 AM
Ill sell mine if anyone is interested. make an offer
original price paid

At this point I wouldnt even consider anyingthing under 3BTC. Have you seen what these are selling for as of now one eBay? NOT 1 has sold under $600

http://www.ebay.com/csc/i.html?_sacat=0&_nkw=usb+asic+miner&LH_Complete=1&LH_Sold=1&rt=nc
I guess eBay'ers don't know about group buys... let me fix that for you...

mine is up for grabs here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=281114470585
How do you accept bitcoin as payment at an eBay auction?  Do they allow that?

one more straggler just paid.  me.
What?? How'd that happen? lol.
There's only 12 people that haven't been marked paid on the spreadsheet yet.  Must be one of them right?
15  Bitcoin / Hardware / Re: [Announcement] Block Erupter USB on: May 08, 2013, 01:39:55 AM
I love all the posts from people acknowledging the ridiculous price, then immediately saying "put me down for 10!!!!"
I know, right?

The current site owner no longer has interest in maintaining the site.  I am talking to him about taking it over and getting it back up and running!
That will be nice if you could get the site back up.

I have tried airVPN.  Pretty good service, they don't care if you give them fake information and they don't keep logs.

At blockchain.info one of the things you can search for is the firstbits of a BTC address.
I guess the address needs to be registered first at firstbits.com before it will appear in the results at blockchain.info.
(Is this assumption correct?)
I can't do that because for the past 3 days (probably longer) firstbits.com has been down.

I do understand each firstbits address needs to have at least one transaction first, which the ones I'm trying to register their firstbits, do have.

They are a couple of Casascius physical bitcoins which on the outside only have the first 8 digits of the public address printed.  So if I were to sell these coins I'd have to also provide the full public addresses so the buyer can look it up on blockchain to be sure the coins are funded.  Or find out how to submit firstbits.

Edit: Even though blockchain.info doesn't find the firstbits (first 8 characters), blockexplorer.com does find it.  Still wondering how to add it to blockchain.info; maybe they are discontinuing firstbits?
