My guess is because he is using the FPGA Single already and ran into it before. You have to go through the same thing with the USB drivers for the latest versions of cgminer, so I would assume the same is true for bfgminer.

Not only that, but even if you have fixed electricity costs like I do, heat becomes a concern. More power = more heat.

Seriously, "...don't cry..." about not getting the product you should have had months ago? I feel like they truly care about me as a customer.

Which is why I'm thinking these possibly won't need it either. They use an external power supply which should already have the UL certification and FCC might be excluded as "commercial test equipment" (that may be a stretch). It seems hardly worth bothering to go for the certifications unless the FCC comes after them. I doubt it will even hit their radar.

EDIT: Of course, Phinnaeus Gage pointed out that Josh said something about getting it. I don't know if that means they need it BEFORE they ship, or if after is OK.

He has every right to make this offer, we all have now just placed our opinions that it is a terrible offer, the best thing is to probably just let it be what it is. People can take it or leave it.

I personally think it is the wrong place for it, but whatever, I'm not a mod.

Arctic Silver is awesome, but I started using Arctic MX-2 instead because it is non-conductive and non-capacitive, yet is almost as a good at heat transfer. I'm big on PC water cooling so I have a big ass tube of it.

You know these are the FPGA's and not the ASIC's right?

That looks like it is caked in it compared to how mine was.

This link is actually rather interesting: https://www.sparkfun.com/tutorials/398

"What can I do to avoid expensive testing and still remain in compliance with the laws?"
"A digital device used exclusively as industrial, commercial, or medical test equipment."

But that doesn't make any sense. Why does my TV from China have to have that and UL? There has to be something more to it.

You are correct, I should have said hashrate. Performance would indeed be a combination of the two.

And no, no kool-aid. I've just already been through this before with the FPGA. It was late, I was pissed, I tried to cancel. Then I changed my mind, waited, and the FPGA showed up and has paid for itself many times over.

I just went into this knowing exactly how they work, good or bad.

What about the other mining devices? Do they have any of those certifications?

BTW I'm not being a troll. I seriously don't know the answer.

BFL is going to end up shipping the product. It will use more power than they said, take longer to get, but will have the stated performance. Exactly like the last time.

So if anyone has BFL SC Single's they want to sell for $0.20 per dollar owed, please let me know instead

You keep posting this without answering why they need that when the BFL FPGA did not? There are no CE, UL, or FCC tags anywhere on it, yet they shipped plenty of them. As far as I can tell, if it doesn't directly deal with AC, and doesn't directly deal with network, it shouldn't need any of that.

Does any custom miner out there now have any of those?

Yeah, I know the first few replies... blah blah scam ASICS... blah blah whatever.

Anyway, for anyone that has a BFL FPGA, I always thought I just got one that wasn't a great performer. It has always done the stock speed, but ran really hot.

The fan on mine started making terrible noises so BFL sent me a new one. While I was taking it apart to replace the fan, I figured I may as well put new thermal paste on since I have a giant tube of it. Well, to my surprise there was NONE on there. It looked like the heatsink was just put directly on top of the FPGA's. I put some paste on, mounted the heatsink, and it now runs at the second fastest firmware they provide, and it does it about 20C cooler.

In case anyone runs into this like I did, it is perfectly possible to do this. I just got it up and running with cgminer 2.11.4 on a BeagleBoard revision B5 board. I just used the Ubuntu instructions here:

Then built with the cgminer instructions. My BFL Single is happily hashing along with no problems.

Just so you know, your store doesn't seem to handle passwords very well. I use random passwords that are not all alpha-numeric. It accepts the password when registering, but then rejects it on logging in. I ended up using one that had no ()[] or {} in it and it seems to work.

Well... Ticketmaster is pretty close.

Except why would you want to lock out using PC cooling hardware which is already abundant and easy to buy? It will give a lot more flexibility in the long run.
