[Announcement] Block Erupter USB

[erk]

The fact that AsicMiner is the fastest gives them an option to price their products with 300% profit margin.

And boy, they use each opportunity to do it and will as long as there's enough suckers to buy. And it looks there is.

The Klondike 1 USB ASIC stick, will be a direct competitor and come in at a fraction of the price.

Can Klondike deliver next week? I don't think so.

Final price is more important than rapid delivery. If I didn't care about price I would go to my local computer shop right now and get a HD7990 GPU and be mining at 1200MH/s within the hour and making over $125/mth. on top of power costs at the current difficulty.

Even priced at 10 BTC they would have a good sale.

 10 BTC would have indeed been a good sale... for the ASICMiner shareholders.

 For the purchaser, not so much.

2 x USB Miner vs. Radeon 7970, a simple power calculation for german users:

7970: let's give it 180W (GPU only) -> 0,18 kWh x 24h x 31d x 0,27 EUR = 36 EUR / month ~ 46 USD / month power costs
2 x USB Miner: 5W -> 0,005 kWh x 24h x 31d x 0,27 EUR = 1 EUR / month ~ 1.28 USD / month power costs

Well, in my book there are no open questions...

I am well aware of that calculation.

Still as someone else in here already wrote: The stick definetly is overpriced because production cost can't be that high. From what I found in those forums the current per unit price for the Avalon chip in BTC is at about 0.09 in the group buys.  Someone else in the forum is offering to build 10 or 20 chips into a nice miner for just about 1 BTC on top of the cost for the chips. That's essentially the same price as the Block Erupter at ten times the mining power for the 10 chip version. And I am currently looking into hopping on that boat instead of wasting my money on this thing here.

Okay, that's right (asuming, that DIY Avalon eventually works). I was just referring to the "GPU is better / ROI of GPU is better" - statements.

Do you have a link to this thread that you mention?

I completly agree... But I'm sure they would sell a lot at 10 BTC, but only the first batch. AFter that one, they would sell almost nothing

Je moet ze via een groepsaankoop proberen te bemachtigen. Kijk voor meer info hier: https://bitcointalk.org/index.php?topic=207326.0

Maar ik zou het niet doen, ze vragen meer dan 2 BTC, wat wel héél duur is. Ik wacht nog even tot ze goedkoper worden.


Translation: I referred him to the Europe group buy and said that I would wait  for price drop.

The mathematics on this product don't work out.

Minimum order of 300 units at 1.99BTC each = 597BTC

Assuming a mining difficulty increase of 10% every 11 days or so, in 6 months time at 90,000Mh/ps you will have earned back 385BTC - and by then you'll only be earning 0.77BTC per day. In a year, you'd still only have 456BTC, and you'd likely never get back to 597BTC unless you increased your hashing rate by buying more units. Plus this is assuming a start date of today - likelyhood if I placed an order today for 300 units, delivery could be any unknown time in the future when the difficulty has already gone up x amount. 

Naturally, the difficulty MIGHT not go up 10% every 11 days, and the value of BTC MIGHT go up a lot, but there's no way to tell. 

At current rates 597BTC will cost you ~$73,500 - not many people have that amount of money laying around, so most would have to get a loan to do so - so factoring in an interest rate for that too, it's just not viable IMHO.

There is so much guessing in those posts. Why don't you look at the BTC/USD exchange rate 12 months back and guess it will be the same during the next 12 months. Will it make sense then?

Introduction


The Sapphire Batch

This is the first batch under production in quantity. Its lead-time is conservatively 15-20 days.

Ok, this was posted 4th May, 15 days are up, difficulty is now 11.2 million, it will be 12 million in 6 days.  So lets see some screen shots and youtube videos of you guys hashing way at 300mh/h and only pullin 3 watts.

Hurry please , as us BFL customers know every day passed you have bought into a depreciating asset, especially one that had a $0 ROI to start with.

Thanks

Little tired of so many people judging each ROI like you only get one bet...  No guarantee that the DIY efforts will be timely and without issues

My miner history is:

Used GUIminer and my dual gtx460s to weakly mine at 146mh on main pc
Thought about BFL minirig in March, researched two days and smelled scam and passed.
Would of pulled trigger on Batch 3 Avalon but didn't have the BTC ready in time. 
Bought ModMiner for 8btc last month to free up main pc and reuse old pc rig
Buying 4 usbees to add to old rig to have 2gh mining
Buying 38 Avalon chips for 2 klondikes and some nanos


Even if my ROIs are long, it is like putting my bitcoins in a silicon mattress that I will still have plus the hardware still mining what little they can do

We all wish we had a first batch Avalon but that ROI is the exception and had plenty of risk too.  Looks like batch 3 avalons aren't looking very great ROI right now either

The DIY Avalon boards are a low cost alternative BUT, for the sake of cost purposes, they are designing a board without a FPGA chip and that goes against the Avalon design. Until we see a working prototype, the first DIY design could be a failure. We don't even know when the first chips will arrive. It could be a long time before a working DIY board is made and the cost could increase substancially.

I'm purchased 20 of them.

The plan is to hook them to a Raspberry Pi.  Do you think it can handle communicating with 20 units?

Powering them seems to be another issue.  Could a socket be soldered to the board to power them, instead relying on the power from a powered hub?

Wow thats one hell of an experiment. I plan to use one with my RPi on a powered hub.. but twenty. Im not sure man haha.

[rupy]

I would want to run my one off the RPi internal hub directly, but I guess that's asking for trouble!

I'm still wondering which brands produce qualitative 10 port powered USB hubs, seeing the China ones are not that trustworthy

Anyone?

Be careful of el chepo chinese hubs. I bought a 7 port (powered 5V 2A) one for my ztexes, which by the way does not draw power from USB... I get all sorts of errors on it. Got it to work with max 2 devices after disconnecting the 5V line from host <--> hub cable.

For Block Erupter USB  ud need more power. like ~0.5A per port... so if its 10 port hub, make sure u got 5V 5A adapter with it.
