I've been trying to estimate the margin cost for ASICMINER to produce the USB Block Erupter. Given that the processing unit that is placed on the stick has similar characteristics to Avalons chips, I'm assuming the cost per chip is also similar. Avalon are selling their chips for BTC0,078 per chip, but I don't know what profit margin markup they are using at that. Let's assume 100%. That means the margin price per chip is BTC0,039, ~4 US$. The chip is not the only thing on the stick, but the other components are very cheap. Say $1 for the rest of the components, $1 for the PCB and $1 for the manufacturing process. That's a total of $7 per stick.Thoughts? If you have any other way of estimating the margin cost, please post it in this thread.

Every time a block is mined, a certain amount of BTC (called the
subsidy) is created out of thin air and given to the miner. The
subsidy halves every four years and will reach 0 in about 130 years.

Here's a nice picture of the components on the stick (rev 3): Here's another (rev 2):

You must be very near to the truth... and I paid 2.47 BTC for each of mine...

I bet one of the ICs on the board is the most expensive -- you could look up their prices pretty quickly.

Don't know if this helps...

Here's my identification of the parts. The layout seems to match this identification. I've also included a per-unit price estimation, based on 10,000 unit quantities at digikey. Top left: NXP Semiconductor 74HC574 (octal D-type flip-flop), about 0.12 USD Top middle: Atmel ATTiny2313 (8 bit microcontroller), about 0.72 USD Top right: Silicon Laboratories CP2102 (USB to UART interface), about 2.30 USD Bottom right: Alpha & Omega Semiconductor AOZ1021 (3A synchronous buck regulator), about 0.50 USD

So maybe $4 for all components, excluding the bitcoin ASIC? That puts the total margin price at $10 per stick.

ASICs using existing tech are generally between $0.5-$2 per chip dependant on order volume.
They are making a tidy profit on anything above a $10.

id probably say about $15 total to include manufacturing and all the background stuff maybe testing to but yeh Avalon are really screwing people over for these but does that really surprise anyone the company with the least amount of resorses managed to pull the rabbit out of the hat and are quite welcome to make as much profit as they can out of it and there still the only really player in the market thanks to all these idiots that have let the projects die or tried to over design things like BFL Avalons strategy of going with more chips for the price of power worked they required far less design and where much much easier to get made.... they also went with china to make the things which in my books on getting the things to market will beat anything made in the EU or USA by months ill give it to the chine's when it comes to building and getting it done fast there the ones to go with

I think you are a little low.
Things you did not consider:
PCB price to design, build and mass produce. Fabrication cost of device (assembly, attach heat sink/case) Fabrication of heat sink and case Cost to print pretty logo on case
Here is my best guess:
ASIC chip: $7 Other chips: $4 PCB/USB Plug: $3 Case/Heatsink $3 Assembly $2 Packaging $1
Total price $20 out the door.
Many knuckleheads on this website and Ebay paid (and are still paying) $230 USD (1000%+ markup) on this item
What is even funnier is at $20 a stick the people making these are sticking them in USB hubs at $20 a pop and mining 50-100Gh for about $60 a GH which is pretty reasonable for delivery today.

Disagree their chip isn't new enough tech to demand such a high price especially after NRE has long since been covered. They are paying a lot less than $7 for 300mh/s, as are Avalon.

Research, design costs and so on aren't included in marginal cost. Here's a definition: In economics and finance, marginal cost is the change in the total cost that arises when the quantity produced changes by one unit. https://en.wikipedia.org/wiki/Marginal_costStill, you might be right that I'm a little low on the marginal cost.

Is it safe to assume that the marginal cost of the ASIC used is $2 or less?

Unfortunately the heat produced by one asic chip is already too much.

Just being a little nitty here but there is a substantial difference between mark up and gross (profit) margin. While it doesn't change your end result in this case as I assume most people understand your meaning, technically there is a big difference. FYI it is impossible to have 100% gross profit margin unless your cost of goods is zero, it is also impossible to have more than a 100% gross margin.

Good point, I changed the OP.
