Its a fair question and I don't have an answer yet.  We haven't had a chance to do much EM testing...we can find this out fairly soon once we are past the current production hassle.

Once I get my boards in (another epic story for another time and place), I'll run tests.  It shouldn't output higher frequency emissions than the core clock frequency, which at the power level of the chip, should be safer than a cellular phone at its power levels.  If anyone is really concerned, just buy some 5mil thick copper foil, solder the seams, and ground it cover a jock strap with it.   Will dampen 1mhz to 10ghz by ~120db.

I'll test a chip at various power settings and extrapolate a multi-chip scenerio using a FDTD simu at different densities.


Awesome, thanks!  I have to work in a space with 400 - 500 of these things...I'd like to know too.

There, problem solved!

***CHIPS IN STOCK NOW***

I've received 5,200 chips in trays of 270.  I can sell them for 1BTC/chip as samples.  Since chip price is now pegged to BTC, I'm trying to figure the best way to put them up on the store without extensive hacking of the store code.

In any case if you want chips, you can email [email protected] with Qty Requested and Shipping Address.  We'll invoice you for the number of chips you want.  Meantime I'll try to get something up on the store.

Remaining stock: 4900

Yvonne has graciously agreed to NO MINIMUM QTY.  That's right - you can order a single chip, or two if you want to make matching earrings.

Cheers,
Dave

prices going up for nov?? what am i missing - at this rate based on my knowledge October will likely break ROI but not by much

Obviously if they can't move product at a certain price they will need to lower their prices but it doesn't make much sense for a company (any company) to say in stock prices will be lower than the higher risk pre-order prices.  ASICMiner charges a premium ($ per GH) because their products are in stock.

They can have gazillion products in stock and charge the premium of their lifetime but it's designed for the noobs since there's no way anyone can get a positive ROI with them. In addition, as time goes by, the same product should only cost less, not more since difficulty increases.
ASICminer is THE premiere Bitcoin tourist trap.  That's really what it is.

In all fairness, AsicMiner has been reducing their prices over time.  
USB BE was 2BTC, then 1BTC, then .8 or .9 BTC and then finally .1BTC (for some).  
It just happens that AM doesn't reduce them enough for the customer to still make ROI (which makes sense from their perspective).

Back on topic:  Looking forward to the August deliveries (now with FOUR layers!)   Wink

Hahahaha. Of course it makes sense from ASICMiner's perspective. That's precisely my point so in the end it doesn't matter if they have reduced their prices from ultra-ridiculously non-profitable to less-ridiculously non-profitable (for most). It's the last product on earth an informed miner would buy.

Demand vs supply. If you can sell out units at a price that won't ROI, you do so. Lower price once demand is reduced. Look how fast USB miners sell out even if ROI is impossible.

Will megabigpower be offering a discount for November orders?
 I dont know but no one know and by that time maybe all miners stock might be gone when Aug. order delivery ship out.
My intention is not to be rude, but if you don't know, then don't reply. You are just wasting everyone's time, most of all the OP's. The only person who *may* know is Dave.

   You are right and we dont know anythings then no way  Dave will low price in Nov. also bad for Oct. buyers.

I don't intend to do presales after the October batch ships.  This means we intend to have product in-stock.  Prices will probably go up, not down.

   Thank you

However - as my opinion whether you are recommended to buy or not buy - I don't know your regulations there and suppose they're quite strict, like FCC stuff and EMC tests. Until for example proper measurements of equipment are done - it may be risky to install many of these near yourself due to electromagnetic emission and noise. So either properly designer board and/or filters and/or shielding is required. I hope that this would be clarified soon. This is also true for homebrew devices that you make and don't care about switching noise such devices produce (like I saw in some DIY stuff where powering of such high-power chips are done in absolutely insane ways, or like problems with other asic vendors, you know them by the way likely, where their shipments were banned by customs due to these violations).

Anyway, as far as I know Dave has as well options to install miners in his location - this would be likely safe in any way, and maybe if you install these - before proper measurements done (i.e. in special laboratory with antennas where typically EMC measurements are done) - this maybe risky to install at home,  or at least close to you - so don't sit near miner 24x7 and don't put those close to you.

You should care about that and do not put your health into unnecessary risk. However I suppose Dave will do his best to solve these issues and make device fully compliant for safe usage. However that still won't mean that such equipment can be installed in bulk at home, and should be spreaded in space for maintaining safely low electromagnetic noise. Likely also undervolted boards is nice choice for safety, but all of that should be measured, and likely will be measured, the only delay could be there (and it is basically your choice) that such measurements could take additional time and can't be done before August timeframe. This depends.


I apologize if this has been covered, I tried skimming the thread, and may have missed this. I'm a software guy, not much on hardware, EM emission & noise safety precautions. Can someone please point me to a thread or some resources where I can take the necessary precautions to prevent health risks to myself and those around me? I plan on operating both a BitFury Full Kit, and a HashFast BabyJet in my 1 bed + den apartment. Would I need to purchase special casing/shielding etc to prevent health risks? If I ran both these units in a small well-ventilated den, and I stayed away from the room for the most of the time, would I be ok? Also, if it were to burst into flames, is there some auto-sprinkler device or some shielding I can use to prevent burning my landlord's building down, in the event no one is present?  Any resources/threads on this would be very appreciated!

EDIT: I skimmed the thread more and nobody commented on bitfury's post about EM emmission & noise safety... And this disclaimer came from BITFURY himself!

You could use this for shielding
