FPGA Mining Contract

[molecular]

The system is back in action running along smoothly! Anyone know the best way to set up a cron job to trim the database nightly? Also, I'll upgrade to a larger USB drive soon.
again!

Make a sh-script that does this, then check the crontab (/etc/crontab?). Most system have directories (cron.daily, for example). Just put/link your script into that directory. You can also make an enty in crontab for the script, if you prefer. There's also a "crontab" utility to do this, but I never used that.

How do I buy shares?

[Comepradz]

I just noticed that fpga6 is reporting 0 MHash/s, what happened?

Thanks for spotting that! I rearranged some things last night and must have forgot to restart one of the workers. Sorry about that!

Just realized I forgot to make the weekly dividend announceemt, even though I paid the dividend this weekend....

Dividends have been paid for the week of 1/2/2012!

Total paid to 6000 shares: 10.22168431 BTC
Dividend per share: 0.0017036141 BTC

[tgmarks]

Are you running the newer 166mhz bitstreams on them?

Dividends have been paid for the week of 1/9/12

The biggest dividend yet!

Total paid to 6000 shares: 13.59755802 BTC
Dividend per share: 0.0022662597 BTC

Are you running the newer 166mhz bitstreams on them?

Sorry I didn't answer you sooner... I somehow missed this post. Actually, even better! I'm running 180 MHz on them right now, and have for the last couple days!

Are any shares still for sale/how would I buy them? Sorry I'm new to this

[Mushroomized]

Neat thanks

[SaltySpitoon]

Well, I bought in, and plan on buying more shares. This is pretty cool

[SaltySpitoon]

Well, I'm up to 76 shares, figured it would be worth a shot, anyone that has been in for a while have any thoughts about it all in general?

[SaltySpitoon]

Wait, the MHash is increasing?

[fizzisist]

It's possible. It might require an improved cooling setup, but more testing needs to be done to be sure.

Quick question, I own a few shares and I was wondering if power consumption plays a role in the amount of btc being paid out. While I know FPGA mining draws less power, you still have to connect to a PC. If that's the case right now I suggest you look in to purchasing a raspberry pi linux board run the cluster.

[SaltySpitoon]

Yeah, the Raspberrypi could be a really nice money cutting method when they are officially released, they cost $40? I believe. And, in order to purchase more FPGAs wouldn't you need to sell more stock?

Actually, the way this contract is written, 100% of all earnings are paid to shareholders without subtracting power costs first. I reserved a number of shares for management overhead (8.3% of shares) which earn dividends like the rest. Those dividends go to pay the small electrical costs, mainly. If those dividends are more than the electrical cost, I get to keep the extra. If the electrical cost is higher, I take a loss. It's a pretty small amount either way so it works out pretty well. Other than that, I get no payment for administering the system.

I'm definitely keeping my eye on the Raspberry Pi, but what I have right now works pretty well, too. I'm using an Atom based mini-ITX board (this one) which cost $100 and uses about as much power as one X6500. It runs bitcoin-mining-proxy, munin for monitoring, and does some other light serving for our house. This isn't owned by FPGA.contract, and wasn't factored into the power cost calculations when I set this up.

And, in order to purchase more FPGAs wouldn't you need to sell more stock?

That's correct. I'm not retaining any percentage of the earnings as cash for future expansion, so any expansion would come from releasing more shares. The talk about adding MH/s is about increasing the clock rate on the FPGAs we have already. We're using 180 MHz now and we started with 125 MHz way back in October. I've tested up to 200 MHz, but if the cooling setup isn't good enough we could burn out the FPGAs. I need to do some careful testing before I set it to 200 (and forget it).

[SaltySpitoon]

You could always put your computer + FPGAs into a freezer.

Combine a raspberry pi, fpga miner, battery and solar panel. YOu could sell autonomous mining machines, they could scan for wifi, crack the code (if needed) and begin mining all while recharging the battery with a solar panel(which might be kind of hard, considering solar panels are not so great yet) It would still be cool to have one.

Put it all into a CubeSat kit and send it to space. You wont have to worry about the temps plus the solar panels would be much more effective outside of the earth atmosphere.

This would actually be awesome
