I've never seen 20a installed anywhere here in the US unless it was specifically requested... unless everyone has been installing 20a circuits and not installing the 20a plugs with the T shaped blade (NEMA 5-20) to go with them.

Are you sure on that? I don't know of anything in the US NEC that requires 20A branch circuits and would be very surprised if homes from the 80s were all 20A branches.

New US homes all have 120v 20a since about the 70s.

What do you have for wiring in Australia, 16gauge? Here in NA the standard is 15A on a 14 gauge run and 20A on 12g.

Also, power lines aren't constant current sources. A 120V 15A line won't be more dangerous than a 240V 10A circuit despite the higher current rating since most electrocution scenarios won't pull anywhere near that current. The shock hazard is higher at 240V.

Most breakers in germany are 16A with a voltage of 230V which results somewhere near 3.5 kW per circuit. Most electrical equipment (like portable socket outlets) is rated for 3.5 kW, too. Most contracts allow up to 20kW.

Aus, 240V typically most power cabling is rated 10A = 2400W
Of course no one wants to be near the limit

Looking at the different replies - it seems that 1500W is probably about as high as any device should go to get general acceptance for everyone.

(aside, the whole advantage of 240V is it's the A that kills you not the V - thus also higher power with lower A)

20amp (230v) breakers are not unusual here in the UK. Unless you have really old electrics, then maybe it's 10-15.

Euro 230v seems to be 20a sockets the same as the average American home has 120v 15a.

That's amazing.

Here in Finland it is not unusual to have 16A breakers in ordinary homes to supply simple wall sockets. That, and our higher voltage (230V) makes it possible to use electric appliances up to 2000-2500W without any special arrangements. I don't know about rest of the Europe though.

I found BLF to be well priced, There is not much advantage going to the 30k$ device (+10%)

Without much reasoning I'd say a 300-400w device is convenient in term of extra heat.

The size should not exceed that of a typical computer, and having it look like one would reduce the risk of theft / unwanted questions.

Thanks for the link. It would be nice if we had a wiki page, listing all the known ASIC competitors, their proposed product lines, their location, their specs and their production schedule.

While it's essential for the ASICminer business anyway to gather all this information and compile into a business plan, I think it would also help newcomers to make informed decisions and to determine which company provides the right product for them. In the long run we probably also see a product split, where companies follow different marketing paths. Some may concentrate on large-scale miners, others on small scale miners... History shows that companies which try to satisfy all needs, don't really do well in satisfying anyone.

There are some practical limits. E.g. one target spec is about 1200W-1500W per device, because that's what most US households can deliver per breaker (10A) (probably 1200W to allow for some buffer). Other countries may allow more or less. Dependent on the target customer base (US might not be the majority ) that number may have to be scaled.
Above 1.5kW you're looking at custom power supply installations, where usually an expert has to be involved.

Then there's a sweet spot for the price of course. Not everybody wants to invest >$1000. Maybe $200. But that's easy to determine. Just ask the customer.

However, as far as the small scale miners are concerned, I think the defining feature is mobility and plug&playability. This is deduced via inversion: If the miner would be concerned about efficiency and the economy of mining, he'd opt for a solution which maximizes Hashpower / equipment cost, which tends to reduce for smaller devices... , it's the same reason why desktop computers provide more bang for the buck than laptops. For that very reason a lot of large scale miners don't do any casings at all... it just cuts into their competitive advantage.

Now the interesting question is why would people opt for a small scale mining device, knowing that it provides less MH/s/$ (just look at the BFL pricing, 23MH/s/$ vs. 30 MH/s/$). I just have to assume that people sacrifice 7 MH/s/$ for the mobility factor.

Another ASIC plan announced, also from China, with sound track record. It's ngzhang.

The price of the mining rigs starts to go down.

In business aspect, we will learn from the market what miners want the most.

In technology aspect, with the current restrictions (mainly heat dissipation), the weight, hashrate, and price per
each miner could be made very small, but the space consumption probably won't be as small as, say, a typical USB flash
drive's.

Friedcat will you be producing any small scale miners in the future like the BFL Jalapeno?

As long as you have bitcoins you have a piece of the action
Anything else is investment into the infrastructure of bitcoin. It's a way to increase the amount AND value of your bitcoins - but with the risk that you'll lose them. A double bet so to say. You need both to succeed.

Hi Niko

The reason is, I am excited about the whole bitcoin idea and want a piece of the action asap.

I appreciate your reasoning, thank you! I will tread carefully.

Long live bitcoin..

Hello, and welcome to the forum. You can find most of answers in https://bitcointalksearch.org/topic/m.1088043 There you will see that the IPO is finished. You are still welcome to buy shares on glbse.

Also, it seems that you are impatient with your coins, and not willing to spend time researching and learning. If you are looking for a quick fix, your coins will be gone before you know it.
Take care and take time.

Hi

I want to invest about 100 BTC in your business.

What kind of returns can I expect? How will payouts work?

What is the liquidity?

Thanks and good luck.

Long live Bitcoin...
