My question is though, is this actually profitable?  As of now, with 100 shares (aprox 35 BTC) you earn .25BTC per week. I understand that you also own the stocks as well, but wouldn't it be more profitable to just trade btc on mtgox? Or is the investment in the hopes that Hash rates will increase, and more fpgas will be added eventually?

Bought Shares. looking forward to seeing how this goes.

You do have to worry about the temps.... your equipment can get very hot if you are aren't in the shade of the earth or moon.  And you have to be out of the shade for the solar panels to do much good.  Also, where is your internet connection coming from?  Anyway, let's take this to an new off-topic thread, pms,  or drop it.

I'm on it. I'll have to do some test runs first though, so instead of wasting all of the stuff sending it into orbit, Ill be launching various other things. I'm hoping bad dragon will sponsor me in my first attempts to Penetrate the atmosphere!

This would actually be awesome

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. 

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.

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

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.


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).

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?

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.

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

Wait, the MHash is increasing?

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?

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

Neat thanks

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

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 you running the newer 166mhz bitstreams on them?

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