Thanks again to all for playing, and to BTCDIG for running a suitable pool.

'way back' 
Perhaps again next year, or perhaps I'll organize something with nanofury-class devices.. since that's essentially an artifact of a era past in its own right. I'd say keep an eye on my StickMiners thread, as that's the most likely place where I'd announce anything of the sort.

Congratulations to BEUSB@3 (Dunkelheit667) for winning BTC0.1 - their winnings will be paid out to the address of their choice.
Congrats Dunkelheit667.
Thank you doubledave! Will cross my fingers for you during the next event.
And thanks again TRS for organizing this lottery/providing the wonderful graphs and of course the price!
Just received the 0.1 BTC and will keep mining with this lucky BE for fun until my raspberry will take care of something else.

As you can seee, BEUSB@5 did not meet the 90% valid hash rate requirement, and is therefore disqualified. This leaves the following:
Qualified participants (index and miner):
Winner selection:
First block mined after 2015-05-04 12:00am (7am UTC block timestamp): 354892
Block hash and last two bytes: 00000000000000000fe61fbc01011127e556418399c1bcc15e08acdc9fa85700
Decimal value of last two bytes: 22272
Number of qualified participants: 5
Decimal modulo participants: 2
Add 1, look up winner: 3. BEUSB@3
Congratulations to BEUSB@3 (Dunkelheit667) for winning BTC0.1 - their winnings will be paid out to the address of their choice.
Clean-up
As mentioned in the first post, you're welcome to continue mining at BTCDIG - I'll keep the workers live so no machines throw unnecessary alerts. If you'd like yours explicitly disabled, just say the word. Continuing to mine there however will not yield you any payment. Disclosure: payment address is the one used for this contest. Automatic payout is set to BTC0.01 (minimum allowed). Donation level to the pool is 5% (maximum allowed). Expected reward, balance, etc. can be viewed via the API.

BEUSB@6 is indeed performing much better.
BEUSB@4 still has zero rejected shares (doesn't matter for the lottery - just surprising)
If anybody was monitoring the hash rates and was wondering about BEUSB@ID...
...I had to stop it for a little bit to take some pictures and video, plugged it back in proper, and after a little while:
Idle for more than 60 seconds, declaring SICK!
Not responded for more than 10 minutes, declaring DEAD!
And it wasn't wrong - tried restarting it, but I suspect it's done for. Not entirely surprising after the abuse, but unfortunate nevertheless
BEUSB@ID of course doesn't partake in the lottery - but I'll drop in a relatively fresh Block Erupter USB just for kicks.

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.
kano keeps a bunch binaries in his repo:https://github.com/kanoi/cgminer-binaries
I'd stick to the rpi though

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.

crossing my finger the pool will find infinite blocks during the next three days <-= you could have a ROI as well.
Well, 264 blocks to go... I'd take it May 01, 2015, 06:23:38 PM
Thanks a bunch! Just plugged one of these little pieces of history in and hashing away. It feels like 2013.
But with greater ROI (though FUN > ROI, of course)Also, out of interest, who's using what versions of cgminer? I'm on 3.1.1 with the -S flag in play.
bfgminer 3.10.0 - don't judge me on this - just had it installed on an rpi located close to the BE.

Fresh install of BFGminer 5.1 for me. I haven't been mining anything via USB since I turned off my silence/efficiency modified BFL singles last year (40GH @110W vs 60GH @300W).
https://forums.butterflylabs.com/post-sales-and-customer-service/8261-underclock-single-2.html#post81128
Same here. I have 6 BFL singles modded to 0.8VDC. Think they use about 120W. Using CGminer 3.12 for my BE.

Maybe I should mess with y'all and point a few TH of old gear at it for the weekend.
Haha - I'm sure the pool operator wouldn't mind Oh well, no reason to turn it off now. It's on the same machine I've had the GPU running 30Mkey worth of humorous vanitygen addresses (1buttcheek, etc) for about the last five months just because.
Ever thought of pointing that at the vanity 'pool'? I'm still half tempted to dig into FPGAs and seeing what sort of performance/efficiency I can get out of a reasonably modern Xilinx for vanity generation.Slightly back on-topic:

BEUSB@6 does seem to dip out of bounds, I'd check on it

I forgot the start time and my block erupter was at the shop. If I'd thought about it I'd have set it going before leaving work last night (8:45 local, 6:45PST) and been okay. Maybe I should mess with y'all and point a few TH of old gear at it for the weekend.
Oh well, no reason to turn it off now. It's on the same machine I've had the GPU running 30Mkey worth of humorous vanitygen addresses (1buttcheek, etc) for about the last five months just because. Woo, add another 2.5W to it.
As for modding, I'm not sure I'll have the time to do what I'd really want to for one. Novak's walked on his sweet idea, we got too much other stuff going on at the shop these days. I guess I could hijack one as the USB/UART for my Compac prototype and add that to the competition but I think I'd rather do nothing than do something halfass.

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)
The apparent hash rate at the pool stabilizes fairly quickly thanks to the low diff - while your miner does appear a bit slow, it's within the range I had determined out of my batch of 8 + bit of margin.. as long as it stays there, it'll be fine Jump to:
