The first mass production batch (sapphire) has finished its PCB production and assembly today.

It has significant improvements in:

Heat reduction: 560mA (emerald) -> 500-510mA (sapphire).

Stability: We stressed it with 9 Block Erupter USBs in a row without heatsinks heating up each other in a very dense USB hub with 25C without active airflow. No unexpected (non-probabilistic) HW errors ever happen.

Speed: This comes after better stability. Now the hashrate converges to its theoretical value of 336MH/s.

Appearance:
  Manual assembly (emerald) -> SMT machine assembly (sapphire)
  Standard heat-sink (emerald) -> heat-sink front-case 2-in-1 logo-ed (sapphire).
  LED added.

Four types of front-case:

All of them are eager to be powered up and hashing!

We had shipped the first 200 USBs today immediately after they are out of the factory. Soon more than 10,000 shiny little stones will be distributed international and quietly erupt blocks.

nice it will better if you reduced the price :) .

Can we see it?

Lower price with lower order limit (under current 300 batch order) would be nice ;)

While i know that they are 1.99 bitcoins, i don't see any price in this thread.

I just came  ;D

Send me a test unit? I'll be happy to review... :)

Cute appearance. I like it.  :)

I take it the color variations are distributed randomly?

Gotta catch 'em all , eh kids?

If only they had it in pink..with a few cute designs. Send it to Japan they'll come back with Hello Kitty all over it.

sick

where can i find some information about the speed of this unit, prices etc ? possibly order one aswell

I take place  :)

I love the red (pink) one!

Which means they are already sold out?  ;D

The new ones look awesome!

If you would be so kind to throw in one old heatsink with the shipment to xyt I would be very grateful. I really prefer the industrial design!

ditto - new sinks are cute … but a bit too 'pimpin', no?

aw hell, whatev - go on wit'cha bad self.  stick a feather on that cap, son.  Work those blocks!

seriously - nice to see a fun design for a change - well done.

Love it!  Great job!  I can't wait for mine to get here.  :)

Wow! I'm so used to BFL and Avalon I'm shocked at how "fast" these came out.

Great job.

Awesome work! Keep it up!

You can order one or more in my group buy!

https://bitcointalk.org/index.php?topic=195540.msg2032724#msg2032724

It works with mac?

Buy them here:  https://bitcointalk.org/index.php?topic=195647.0

Is there a German group buy?

looks damn nice

thank you

YEAH!!! GREAT NEWS FOR ASICMINER SHARE HOLDERS AND ASICMINER ALL TOGETHER!

yes, but closed...
https://bitcointalk.org/index.php?topic=195037.0

I'll test it out on a few Macs as soon as I get my sticks in.

why? they can't make roi ever, they are useless...

Where could I buy one?

Jizzed in my pants.

oh... oh my.

Not being an ass but can you elaborate?

Make these available on bitcoinstore.com and I'll buy one.

Also available in group buy:
https://bitcointalk.org/index.php?topic=201577.0 (https://bitcointalk.org/index.php?topic=201577.0)

Do these require a serial connection over USB drivers (FTDI)?

it's the expected onlining of all the other aisc stuff. avalon, but their own units and the chips, the 100th mine, bfl, etc. difficulty is expected by most to launch like a saturn 5 rocket and leave the moon in it's wake.

if that actually happens, ROI with these will go from the current 4 or 5 months (or whatever it is) to longer and longer, until eventually the electrical cost of running one, plus the host pc, exceeds what it earns.

Yes ROI is going to be rough, but you have no idea of what the future price of BTC will be.

Also, buying one of these; just for the _fun_ of it and helping the BTC community, is more important than how rich you get!

It's the idea that is important, not the product!

+1

Good Work, look great.

Your math is wrong - roi on these at ~2btc each is 4 to 60 months. I definately isn't the best option because of the sidecosts associated with running 300 of these... but it definately is doable

I've said it before: 0.5BTC or under and maybe we'll talk. 2BTC is just ridiculous.

Just to nail the point home, these have a MHash/Sec/$ rate of approximately 1.31 whereas an upcoming KNC Jupiter has a MHash/Sec/$ over 50.

https://en.bitcoin.it/wiki/Mining_hardware_comparison

These little guys will take approximately 38 x longer to receive a profit.

Oh, and the value of BTC doesn't factor into the equation at all as you are paying in BTC and receiving BTC through mining.

However, that being said.  I think overall these will help drive the price of bitcoin up as people mining with them won't want to sell their bitcoin at current rates.

It's a fantastic piece of kit, kudos to AM for coming up with it

I have to agree 2BTC is way too much.

Glad to see you are making 10,000 of them though, there's a good chance the price will drop to a more realistic level soon :)

I think friedcat should make a version that the hashing power is suppressed. As the time goes on, he may send a command to unlock some of it for another 0.2Btc to keep up with the rising hash rate. This way, he does not have to make a new hardware over and over, and starts collect subscription fee instead.

It also mess with the mind people trying to guess whether of not a device can meet ROI, so they have no choice but to buy anyway.

That 10G blade could be sold for 2 btc using this scheme.

 ::)

I agree with the others, if the price was 0.5 BTC then I'd definitely buy one. No chance of me buying one - or a bundle when they're priced around $240 each. For that price I could get a 7870 which does around 400 MH/s, comes with free games and has a better resale value. Only real downside is that it takes more power, but it can be used for gaming, or Folding@Home as well.

I was thinking he could have shipped them at a discount but locked them to his own mining pool.

http://www.thinkgeek.com/product/eecf/?srp=4

anybody know if this thing could actually power 28 (heck, even 20) of these miners at once? 4 amp power supply, i think.

Very cool! Well done. Too expensive for me but i really appreciate the effort and speed of manufacturer.

blah.. run these off a pi solar powered.  free money

4A, so it could theoretically safely power 7-8 miners (assuming ~500mA draw).

Congrats OP on the rollout. Glad to see big progress on this. Wished I had some BTC to spare but the price is a blocker for me.

Kind of scarry but if you see this as a hobby that should be ok, such as golfing, fishing, paragliding and bitcoin mining ;D

german/austrian group buy:
https://bitcointalk.org/index.php?topic=201958.msg2139583

if you are not picking them up locally it is 10 max for shipping

current status: 197(min) 271 (max)

How can I get my hands in one of these miners?

Go here https://bitcointalk.org/index.php?topic=201577.0

We already have the numbers, we are just waiting for people to pay so we can start shipping

Is this batch still open to purchase?  ;D

Yep, Go here https://bitcointalk.org/index.php?topic=201577.0

Thanks!

austrian/german group by has reached 300 reservation. please check your PM to get in contact with me for details.

Australian code been hashing since 14-May :)
cgminer next release will support them automatically (it already does in git)

With current 3.1.1 you need either
 --icarus-options 115200:1:1 --icarus-timing short
OR
 --icarus-options 115200:1:1 --icarus-timing 3.0=100
N.B. the 3.0 will depend on your chips performance but it wont slow anything down (or hash less) if it is wrong, it will just not report the correct MH/s
The 100 ensures it will hash at full speed.

(Edit: forgot to add of course you need -S device for 3.1.1 for each device also e.g. -S COM1 or -S /dev/ttyUSB0)
And to repeat: next release of cgminer will find them automatically (and also allow hotplug of them)

Also note that temperature is important with these devices.
Mine doesn't have a heat sink and gets between 1% and 1.5% errors with ambient low 20'sC
If you are noticing even 1% errors, cooling it down will almost certainly reduce that.

My recent post about them :)
https://bitcointalk.org/index.php?topic=195004.msg2241307#msg2241307
and a few after that

Look forward to buying some! When will they be available to order? :D

I agree, massively overpriced

As an ASICMINER share holder I approve of as high of a price as possible :)

Now that the order limit has been lowered to 50, is there interest in a Group Buy based in the Western US?  It would be run similar to CanaryInTheMine's at https://bitcointalk.org/index.php?topic=217981.0 (https://bitcointalk.org/index.php?topic=217981.0) but restricted to US orders only.  The cost would be a flat BTC2.1 per USB miner.  They would be shipped by Priority Mail.  I'm based in southern California, so orders from the western US would arrive earliest.  Orders would be collected using a Google Doc form such as https://docs.google.com/forms/d/1BuuD7-o_rmz1hIJrLrBstewoRD_iWt2wrEFiKCpadsA/viewform (https://docs.google.com/forms/d/1BuuD7-o_rmz1hIJrLrBstewoRD_iWt2wrEFiKCpadsA/viewform).  Reply or PM if you are interested, and if there is enough interest I will open it up.

I have an order of these arriving sometime next week :) I will most likely test every unit to make sure they work and then i will be selling multiple units, distribution will be within EU only, price depends if i get charged import tax when i receive them..... pm me if you want to be kept upto date

Is there any benefit to using a USB 3.0 hub or is a USB 2.0 hub sufficient?

I understand that 500 mA must be provided to each miner. Does anyone have a suggestion for the best powered hub to use for multiple USB Erupter mining?

https://bitcointalk.org/index.php?topic=195004.msg2303119#msg2303119

See the above psot

 No benefit to using a 3.0 hub over a 2.0 hub. Sufficient power to each port is what is critical and the USB 3.0 spec does not specify 500mA minimum as a standard.

... and not yet clarified possible issues with USB 3.0 ...
i.e. a few people have seen problems, and I for one, have not looked into it yet to find out what the problems might be.

Estimated ship date? Have any shipped yet?

+1

a bunch of people have received units, check the various group buy threads for pics. there are probably a few thousand out in the wild already.

Also now available on Amazon.com (http://www.amazon.com/dp/B00CUJT7TO/), but at retail/eBay prices.

Will it pay off?

Looking at the graphs at BitcoinDifficulty.com (http://bitcoindifficulty.com/), it looks like difficulty has increased quite linearly by 8 000 000 in the past 3 months, that's about 1.3 million in each 2 week period.

At 336 MH/s, we would do about 406 TH (Tera-hashes) per 2 weeks.

Here's a table of how much we would make if we started today:

Weeks	Difficulty	BTC/2w	Cumulative BTC
2	12 153 411	0,195	0.195
4	14 820 077	0,160	0.354
6	16 153 410	0,146	0.501
8	17 486 743	0,135	0.636
...
48	44 153 403	0,054	2.239
50	45 486 736	0,052	2.291
52	46 820 069	0,051	2.342

So, sure, after a year we'd have covered the cost, barely. If we'd start mining in a month rather than now, we'd just about covered the cost in one year. At that point we'd be making about 50 mBTC per two week, with the amout decreasing by about 3 mBTC per month.

In this model I have not subtracted the cost of electricity, which I believe for me would be about 1 mBTC per 2 weeks.

Might be a fun thing to give mining a try, but it doesn't look like a gold mine to me.

Apologies if this calculation has already been made, I didn't trawl the entire thread.

what did it sell for on Amazon?

yes: https://bitcointalk.org/index.php?topic=219422.0

Just received mine. Wondering how to setup on OSX... Hmmmm?

Here's the correct-link to cgminer's thread.
https://bitcointalk.org/index.php?topic=28402.0

Now I'm selling in EU, I accept SEPA. I'm receiving them Wednesday morning  :)

https://bitcointalk.org/index.php?topic=223111.0

BOOM!!! 77 erupters hooked up and running :) another box of 75 sititng next to me half of them for sale on here :)

Use fabulouspanda.co.uk/macminer

install these drivers http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

plug in the device, open terminal and run ls /dev/cu*

find your device which will look something like /dev/cu.yourdevice

in advanced options in MacMiner put -S /dev/cu.your device then click apply

click start

you're mining!

So are you saying that "macminer" by itself is all that's needed?

IOWs, there is no need to also install either cgminer or bflminer?

What's the expected probabilistic error rate? I'm seeing approximately 1% HW errors (apparently false nonces) reported.

Going now for $525.  I think that's what it was earlier as well.

That's right, just unzip and put MacMiner.app in your Applications folder  :)

have any1 tryed it with Bitminter?

Yes, I am running it successfully on OS X using BitMinter.

for mac OS

2013.06.06 [12:54] FPGA device detected on cu.SLAB_USBtoUART: Icarus

It sees it, but can't get it to hash.  What's going on?  Yes, I installed the driver

Where can I get one?

ONE, so like a group buy?

Wow. For 30 seconds there was a used one for $25. Was going to get it but he/she beat me.  ;D

Selling erupters - https://bitcointalk.org/index.php?topic=224256.msg2389085#msg2389085 2.35BTC each + ostage which is about 0.235BTC within EU

he wazzup? listen i just saw that this is true(i thought was fake but... seems not) so
can u send some or one so i can review here in Brazil? PM if interested.

JFYI i love the idea of easy mining without GPUs and without those boxes as BTF does, even that they say make at least 5Gh/s.
i don't think is true but that not the case here.
But i do have one question...
my ASUS P8Z68-v pro/gen3 has tons USB 3.0 with turbo boost and some stuff that makes way higher that usual, will that make it more fast to mine? or i could use 1.1/2.0 usbs that will work as well equal?

sorry for bad bad English.

i wish u could PM me at least so we can talk

Grammar is not a problem, there are many non-native speakers here, so that's fine.

But using abbreviations and slang terms (like "u" or "wassup") makes it really difficult to understand.

ah sho' know whatchu mean. da cracker ass english language iz fine-ass difficult ta master at times wif all it's subtle nuances an' grammar rules with muh beeotch

penises

Say that with a Scottish accent... Sean Connery in particular.

anyone receive the yellow colored once?

Is it me or do these things become insanely hot? :-) (over what's pleasant to pull & put into an other USB port)
I think I'm going to put an additional bigger heatsink on these...

Nope, I hope friedcat send me all colours this time. I specifically told him that.

Yeah, they do indeed get extremely hot to the touch. I would recommend having fans blowing on them.

I love these :: http://www.amazon.com/dp/B003XN24GY (ARCTIC Breeze Mobile USB-Powered 92mm Portable Fan)

I've been experimenting with these: http://www.amazon.com/gp/product/B002OJN250/

http://forumbilder.se/CEJ31/bild.jpeg

It's not about size, it's about surface.

This little HS doesn't look like much, but it increases the surface by x9!

ASIC 6x6=36mm²

HS 8x8=64mm²x5(one for each blade)=320mm²

320/36=8,8 plus borders on blades and base = ~ x9

Why friedcat made the new heatsink without surface in mind is completely beyond me, specially since the original was!

Is that a custom heatsink? I don't think I've ever seen such a small one!

I guess you haven't looked at many motherboards?  ;)

Anyone looking for these shipped today - I guarantee you that you will NOT find a lower price today than this BitMit auction (https://www.bitmit.net/en/item/36457-asicminer-block-erupters-usb-336-mhash-instock-ships-today)

"All orders of 10+ come with free Anker 10-port powered USB hub"

Ah, sorry - correction: "anyone looking for these shipped today"

How does 2-3 days sound?  PM me if you are interested.

you can also get them using next day shipping here: https://bitcointalk.org/index.php?topic=231673.0

.99 btc? or .99 USD?

The first line of this is wild speculation and is nonsense. It is then followed up with even more nonsense. If there are any newbies here take note of how not to think when getting involved in Bitcoin. There are other ways to grow your coins without having to live on prayers, dreams, and baseless "what ifs"

it's .99 btc from the manufacturer.  I have started group buy #7 here: https://bitcointalk.org/index.php?topic=241414.0 costs 1.01618 ea. @ 10 units ordered.

So you gingerly PM me once in a while and then complain if I "get in your sales" then you kinda insinuate your comform level with setting up some kind of an oligopoly between us (of which I want no part)... and now you want to strong arm friedcat by asking people to flood his inbox with PMs.
how low can you get??? disgusting

Canary, I'm starting to think your goal is to just drum up drama. It's really ok to just attack me on one thread (https://bitcointalk.org/index.php?topic=223916.msg2564080#msg2564080), even if it happens to be my own sales thread. Your voice is loud enough over there that you don't need to crowd other places.

I understand you've had a crappy day, but this is not the way you should treat a fellow re-seller and this is exactly why I feel ASICM should make a decision regarding re-sellers. I'm a friendly guy and I'm being treated downright hostile at present. My post was neutral and just calling on my own customers to share feedback - I didn't involve you at all.

A good lesson to learn here is to work on one-on-one communication before over-reacting. It's often the fastest way to a resolution and definitely the least juvenile.

**Edit** It was brought to my attention that my previous innocent intentioned post may have come off as spam to some. My sincere apologies. It's been moved to my own sales thread only.

Good luck in your endeavors.

anyone now if a group buy is set up for Canada ?

If so please PM me...

Otherwise, I think I'll start one, now that those USB Miner are priced @ 1 BTC and can be shipped from Canada by user teek !

i'm thinking of taking four of those and build myself a coin generating windmill just to keep it cool..thanks

 The mondohub 28's can't power more than 7-8 Erupter USB's. Personally verified this.

4A / 0.5A  = 8

No

i have engineers wasting time on bug zappers just throw some extra wire up in there we good..thanks

How much W does one block erupter use?

2.5W aprox

Alright, thanks. Does anyone also happen to know about how much they total with a Raspberry Pi?

My Pi s running at 3.1W with a 2A power supply. With two D-LINK H7 (8 port hub) and 12 block erupters, and two regular goose-neck fans (1700RPM) I'm drawing 15.1W
