[Announcement] Block Erupter USB

[Kinetic915]

Thanks, friedcat !

That's fucking gorgeous.

That's what we all should have in our rooms if AM decided to not rape people with price but to give something to the network too.

dropped around 11 grand there? whew....

These are some damn sexy pieces of hardware. In an attempt to end preorder nightmares, I took it upon myself to order an entire batch from friedcat up front with 100% my own funds, and I'm selling them all in the US. If you order from me (see my signature), you can expect same-day shipment if ordered before noon. I even try my best to entertain color requests!! I must say I was very impressed with the hardware itself though - it feels like it was designed by Apple - brushed aluminum heatsink, arrives in a custom designed plastic case with foam insulation ensuring safe delivery.

I gotta be honest, I'm having a really hard time selling these things - I truly feel like they will be collectors items some day. My wife said I can keep one of each color so perhaps that's good enough ... for now.

Anyway, if you are in the US and have an itch for one, I guarantee you that you're gonna love it and if you go to the link in my sig, you will find no other way to get one quicker at a reasonable price! Group buys take a while (my brother is STILL waiting for his that he ordered a couple weeks ago)!

So lets forecast from there shall we! Starting @ 0.0104 BTC and $1.27 profit a day for the first 10 days. 1 month profit $38.  3 month profit $90. 1 year profit $155!

And $155 * 45 devices = $6975 presuming the price of bitcion doesn't go up.. (why wouldn't it?) what if it rises to ~250/coin stabily? then his profit margin is that much higher.

Takes money to make money.

No gaurentee bitcoin will rise at all in the next 2-3 years. It's a risky business model that relies on increasing prices it can't control to make an investment work. It's a bit like starting a prefab roof construction company that will only make money if house prices and thus the component cost of building houses doubles in the next few years. All forcasting i see only ever accounts for prices rises within RPI or CPI inflation (which is fiddled down).

My company would fund several new dopots to open today if it could gaurentee selling prices of goods bought today would double in price over the next few years!

Like i said I have my risk based on a BFL product to hopefully be delivered this side of Xmas but I factored in a X 10 increase of difficulty (8m to 80m) from the date of order before I commited cash and it still had an ROI good enough in under 5 months @ 30% increase a month.

For sure with human nature this ASIC thing will grow and grow exponetially, as will the difficulty until the BTC earned is less than a $0.01 /kwh and anyone who pays for electricity (this includes all the current big players) are forced to stop mining.

Will be interesting to see at that point if the price rises to respond or if network hashrate just comes offline until the difficulty drops but the transition between these two will mean transactions will crawl along.

This is already happening with Litecoin where low effeiciency GPUs are no longer making money vs power and high efficiency ones like the 7950 are now making less profit that BTC direct but this price is not rising to compensate. I expect a huge drop off of LTC hashing in the next few months unless the price $ rises a lot.

will get one soon, need to get some food!

 edit: I guess a photo only takes a min -

I know have 7 hubs up and running that is 66 erupters I would have another hub hooked up but it appears the power source does not work!!!! bad anker(came direct)

What is the range of hw errors as a percent of accepted shares that you're getting, please?

On my working one it is running at about 0.9%. (IIRC, several other folks have reported getting about a 1% hw error rate.)

One which is now dead and in the process of getting replaced ran at about 10% hw errors for roughly eight hours. Then it died.

-- edit

NOTE: I had a fan blowing over them. They were both 'warm to the touch'. Not the 'freaking hot' you encounter without active cooling.

Great to hear that you've got the rest running now!  Did you end up running the rest on a second machine (mac)?

I'm getting about 1.1% HW errors across my 7.

would love to add another 2 racks to that photo for ya!

Would love to see photos of that too!

Anker's probably like, "Why the sudden rush in worldwide hub orders?"  Haha!!

[elasticband]

will get a pic up soon

someone should tell them before they ramp up production

...or maybe... they'd just slap BTC COMPATIBLE on the box!

What kind of cooling should I aim for with 50 of these bad boys?  Keep in mind my #1 concern is noise level.  It may be very close to a child's room and I don't want it to be noisy.  The house does not have A/C.  Although I live in Canada, our 2-3 months of summer can still be scorching hot.

... I live in Canada, our 2-3 months of summer can still be scorching hot.   

Uh, NOT.

Yep, 40-45­°C for 3 months here in central Australia will do that

OMG .Fools and their money!  When this was announced difficultly was under 10m and network hashrate under 80t/h.  Now you've got them it's 12m (+20%) and network hashrate is 100t/h+ . In under 3 days difficulty will hit 14.4m.  So thats a 44% increase in diffuclty in 5 weeks, around the 30% + a month I predicted.

All of this is true, but these people are helping secure the bitcoin network by adding to the network hashrate. We should be encouraging this kind of behavior

This is a common fallacy in bitcoin propaganda. There is no secure bonus with higher hashrates. The network keeps secure by an adequate balance of difficulty and hashrate. And this balance is guaranteed by the algorithm, not the miners.

This has the worst Mhash/$ ratio of any asic device out there at 1.22Mh/s per $1. The runner up is asicminer's erupter blade at 1.87Mh/s per $1.

How do they get away with it? Because it's basically the only form of asic being shipped without a pre-order...
