i still don't understand why the price is so high

1 chip + 1 mini pcb + one usb connector = 2tbc, really?

it would have been much better if they were priced 0.50-1 btc, much honest price...

Why does it have to be honest?

 Look at it another way, where else are you going to get 300MH/s running on a USB stick @ ~500mA ?

This is the free market at its finest.  If no one would buy it at this price... it wouldn't be this price.

Ohhh I think it will be dropping in price much sooner than ASM hoped! With you Yanks cheap and easy exit from BTC into Fiat shut off via Mt.Gox and Dwolla I think you might get a nasty lesson in just how important a route to Fiat is for the value of BTC.

Trust me I mine and hold BTC so I want the BTC/USD price as high as possible but I fear we may head back to $50 again in the next week.

If mtgox is that critical to bitcoin, then we have a problem, and an adjustment is in order.

I said pardon ?

You of course realize there are ways to fiat other than Dwolla, right ?

At 0.5 they would be much better than the blades.

Demand meets supply at a substantially higher price than that, it's just that simple.

Mine will!!!!!

Sure. All cheap and easy routes into and out of Mt.Gox got GBP £ have been systematically shut down by UK banks since March. But Gox will happily send and receive wire transfers in Sterling or USD.

Problem is this involves hefty fees and losses in exchange rates from Yen to sterling. This makes smallish transactions into / out of BTC very expensive. Say BTC drops to $50 next week and yep i decide to take two of these USB miners now as in FIAT they have dropped from 2BTC to 1 BTC. But the costs to wire transfer and exchange £260 into 4 BTC can hit 20%!

I beleive Dwolla was popular becaus it was cheap and quick to get even small $ amounts into and out of BTC.

You can still use Dwolla. You just need to use CampBX as an intermediary.

If you want a few of these USB Block Erupters.  Join a buy group.  This buy group needs orders for about 40 more unit.

We also tested it on the USB-hub. Seven in a row run over a whole night and are all very stable.


That's a cute hub! Could you tell me which brand/model that is? Smiley

Ah, DX Smiley Too bad it takes like over a month for something I order there to get to here Wink

Might buy one for fun raspberry projects later on Smiley

Thanks!

Just search your local ebay for "10 Port USB Hub" and you should find it.

Hmm, if the asic chip is on the top of the PCB, and the heatsink is on the bottom, what is it sinking? and why is there no pictures of that side?

I'd assume that the AM design is similar to the Avalon one in which there is a large themal pad on the bottom of the ASIC chip which is connected to the heatsink through the PCB using thermal vias. That's actually a pretty standard practice.

 I was thinking that myself... "Wouldn't you want the heatsink on the top of the plug to radiate heat up instead of through the PCB ?"

1. Get cheap hub from China and get big problems. Here's the review from one buyer...
Quote
WARNING: I have one of these, and they used a 0 ohm resistor where there should be a diode installed. This caused the hub to backfeed power into my mainboard and it blew my mainboard. I very nearly blew the replacement board too but I was being very careful and plugging things in one at a time. The second that I plugged this in to the new mainboard, it shut down instantly. It works OK if I don't hook up the power supply to power this hub. I'm going to unsolder the jumper resistor and put in the diode that should have been in there in the first place, but I won't be buying any more of these.

2. Don't expect the Pi to work with just any hub...
