Re: Use CRIO to mine bitcoins?
 

We keep 1 or 2 robots functional year round. That would give us 4 cRios left over for bit-coin mining.

I don't know all the details of FPGA mining but would 2500 pooled miners be worth while? What about 5,000 or 10,000? Just curious at what point it would start to become worthwhile or if it ever would.

Re: Use CRIO to mine bitcoins?
 

They have to be the new 4 slot cRIOs to be worth it. The older 8 slot models have much weaker FPGAs.

Re: Use CRIO to mine bitcoins?
 

They are actually pretty comparable size wise. I haven't looked into what type of computations are involved in bit coin mining, so I'm not sure if the dsp blocks would make a big difference.

You're right. ;) I agree with saving soda cans making more money. One of our school programs makes around $500 a month doing so. Probably more than Crio mining will get your team. :)

Bitcoin?? Didn't the bottom just fall out of this ridiculous scheme anyway?

Distributed computing has been around for a long time - RC5-64, SETI@home, F@H... Projects that are intellectual or beneficial to mankind.


Sell your scrap aluminum to a recycler. You'll make more money.

Find a fundraiser that's worthwhile, that your entire team can participate in.

Re: Use CRIO to mine bitcoins?
 

Right now Bitcoin is still in a speculative mode. Like any other form of currency, it takes awhile to establish a more consistent exchange rate. Right now people are using it as a type of speculation, but since its only four years old you can't expect it to be 100% steady. All new currencies are volatile. I wouldn't consider a ~$120 equivalency rate as of today to be a ridiculous scheme either, especially if you have the hardware to mine

It looks like using the crio II Spartan-6 fpga you get about 100 Mhash/s so if 2500 teams do 100 Mhash/s you would do 250 Ghash/s or ~$56,975.96 a month

Re: Use CRIO to mine bitcoins?
 

True. In addition, you're recycling waste rather than wasting the world's resources trying to generate ones and zeros.

Re: Use CRIO to mine bitcoins?
 

You're not accounting for the opportunity cost (of whatever those resources could be used for alternatively), the operating costs (like power and labour) or the externalized costs (such as the environmental impact of consuming that power).

Also, 2 500 teams? Not particularly likely.

Re: Use CRIO to mine bitcoins?
 

Also, with the $57000 a month, if you divide it evenly among the theoretical 2500 teams who participated, each team gets a net income of $22 a month. Wohoo, sign me up for my team's Jackson! :D

Re: Use CRIO to mine bitcoins?
 

That is likely the largest Spartan-6. The cRIO's FPGA is 1/3 the size of the largest Spartan-6, so you can expect 1/3 the performance. My guess is it is probably not clocked at the maximum rate for the Spartan-6, so you get even worse performance.

this is all very true I simply did a rough kinda sorta calculation based on the specs of the pci Spartan-6 dev board with the biggest baddest fastest spartan-6 fpga (the only kind clocked by anyone using bitcoin mining software)

Re: Use CRIO to mine bitcoins?
 

"The bottom fell out" his a highly relative term.

It dropped about 40% ($80 or so) after having skyrocketed by three times that. It's not something to put all of your life savings into, but it's not entirely without merit either.

Keep in mind it's only a few years old now, it may very well stabilize in the future.

That said, there's absolutely no reason to attempt to use the cRIO for mining. ASIC (application-specific hardware) silicon has completely dominated bitcoin mining even though it's only been available for a few months. There's not a snowball's chance in hell of competing against that.
