Hi guys

I own few AM block erupter, Also own few pet hamsters. I was thinking the other day, why not get these lazy animal to work for me earning money in full time, they have a running wheel and I wanted to see if it was possible to hook this running wheel up to alternator or something and power small generator. not as 100% power of course as it is too much. just as backup or reserve- maybe I can earn sandwhich from them  Grin


is it feasible, anybody tried?

Of course you can generate power this way but you might need some kick-ass hamsters on steroids to power block erupters Smiley

I was thinking bicycle dyno, but still maybe a hamster would be too light to turn it, a rat or a chinchilla maybe.

Maybe you could use a small electric motor, not sure how much power it would produce though.

Example with one motor turning another... http://www.youtube.com/watch?v=oiIVkp7mMwE

Instead of exploiting animals you could also try a small solar cell or wind mill.  Wink

Only if they pay first and take delivery later... six months later! Cheesy

Any big retailer would sue for breach of contract and take the companies assets if they were treated like us little guys.

If there is a rumor Tiger Direct are acquiring BFL maybe that's how it happened?  Tongue

523  Economy / Scam Accusations / Re: Scam alert technobit.eu on: January 25, 2014, 12:21:25 PM
I don't think they are a scam. This is how my order with TechnoBit went.

1x ordered 19th Novemeber for Decemebr Batch 1 was delivered by Dec 13th (Shipping €30 DPD) paid PayPal
1x ordered 22nd November for December Batch 1 was delivered Jan 22nd. (Shipping €4 bigger order) paid BitBay
4x ordered 23rd November for December Batch 1 was delivered by Jan 10th (Shipping  €4 bigger order) paid BitPay

I didn't get a tracking number but they all arrived within 7 days of their order system changing from "payment accepted" to "shipped".

Technobit don't seem to able to combine orders so my advice would be never to use the €4 "bigger order" option, it may cause delays because it could look like you didn't pay for shipping! Their PDF file doesn't seem to include your shipping notes like "add to my previous order".

Paypal is back on their store, and as that arrived first, I'd have to say paying the extra 5% for PayPal probably adds some pressure to deliver your order within 30-45 days!

My 22nd Nov order came last, it seemed missed because it was out of date order, so I mentioned it to Martin on the Hex16B purchase BitcoinTalk thread, and it was in the posted the next day! Comms are not great but being nasty to Martin won't get your order out any faster.

Sure I'm not happy with how long my order took, but all Bitcoin miner manufacturers have delays, Butterfly Labs took 6 months+ to deliver some of their orders, my Technobit experience was much better. These things are custom made, and they cannot make everyones order at the same time, if you want fast delivery, order from someone on eBay who has a miner in hand, but be prepared to pay up to double for the privileged.

I always wonder why Eligius does not have a much higher portion of the network

Because they screwed the small miner over with a wacko payment system and kept all the NMC (back in Oct 2012). I wouldn't mine there again.
Can you give more detailed explanation?

It's all on record in the pool thread somewhere around Oct 2012. I was warned not to use a 0% fee pool. But I was newbie and didn't listen.

A pool can extract wealth from a miner in more ways besides a % fee, like using delaying payments for currency arbitrage, or loaning to shorters, or secretly merge mining an alt coin.

A pool or exchange can be crippled if it's caught on the wrong side of an arbitrage bet. This is where I suspect many "we were hacked, the coins are gone" problems start.  Wink

I don't leave any more than a days worth of mining on a pool now, if I can't cash out daily, I wouldn't use it.

NEW 1.2Th/s 28nm ASIC Bitcoin Miner (1,600Gh/s in Turbo Mode)

As nobody has been able to get more than about 30.5GH out of A1 turbo mode good luck with 40 chips doing 1600GH...

Quote
Internal 1000 watt PSU (draws about 700watts)

...and as it's 1Gh/1W in turbo mode those 40 chips doing 1220GH will draw 1220W!


From bitmine own website:

Technical specifications* of the CoinCraft A1 ASIC:

Developed on 28nm HPP process from Global Foundries
Custom IC package with power bars for low voltage, high current feeding
Configurable in daisy chain mode for distributed work with up to 253 ASICs.
Standard SPI interface
Hashing power of 25 GH/s in nominal and up to 40 GH/s in Turbo mode
Power usage of 0.35 W/GH in low power, 0.6 W/GH in nominal and 1 W/GH in Turbo mode
Supply voltage of 0.65V in low power, 0.765 V in nominal and 0.85 V in Turbo mode
Mass production available starting from the second week of December 2013

Check out the burned boards/chips trying to reach that theoretical 40GH they seem to be destroying them trying to pipe 40W through each chip.
Wink

Why bother maxing out a chip anyway there is no point. You lower the life span for one and for 2 wouldn't it just be easier to get another unit or even another couple boards if you wanted something quicker instead of trying to max out a chip constinatly.



i think overclocking is safe if your unit is in a nice chilled air conditioned environment ..

Very cold air or liquid cooling

Liquid nitrogen more like!  Wink

How much is a lot?

The best bitcoin miner, 3TH KnC Neptune, sells for $10,000 and as it's sold in limited numbers, you'll probably have to offer someone at least double that to get it out of their hands.

= When enough excess power is available the rig is powered on and you mine for free.... In your car!

LAWS OF THERMODYNAMICS = there is no free power!

You will be burning more gas/petrol to power it.
Unless that power is already being generated by your alternator and wasted.

This is a fallacy. A car with it's air conditioning on consumes more fuel than one with it off.
I thought that was because engaging the air conditioning compressor adds a load to the belt system that was not there with the compressor off.  Likewise, I thought the alternator was always engaged, to provide system power and keep the battery charged.  Perhaps I'm mistaken.  

The more power you demand from the alternator the harder the engine works to turn it.
It's like a dynamo on a push bike, the harder you pedal, the more power you generate, and the brighter your lights get.

Not unless they've copyrighted a photo ...

Besides, BFL and KNC did the same things, they took a photo of a chip and then CAD/photoshopped, until they had actual designs.

So if they have not paid the copyright then it is still illegal but that's okay because other have done something similar.

Reminds me of the girl who sold her virginity on the Internet but claimed she was not a prostitute because she only done it once Smiley

No, all i was saying was unless it's copyright protected, there's no wrong being done. Simply taking a photoshopped image from one place and chopping it yourself, isn't wrong. Laws vary by country of course. If it is copyright protected, the image needs the stamp, as does the sourcepage.

But even still, taking a copyright protected image and modifying it.. is different than trying to use the exact same image.

Wrong, copyright does not need any copyright marking or registration, it is automatically implied. http://www.ipo.gov.uk/c-auto.htm

While you can use someone else's work in your own, your work has to be substantially different (trans-formative) from the original. This is not.

This is why there will 2-3 main crypto currencies because the old ASICs will be used to mine a currency with lower difficulty.

See a pretty long list of SHA-256 Alt coins on http://www.p2pool.org/

Are you saying you can "re-program" bitcoin ASICs to mine a different SHA-256 coin?

Yes, you can mine any sha256d coin with the bitcoin asics.

Yes this is correct, bitcoin ASICs just do the SHA256 math, they are not coin specific, they can be used for anything else that the SHA256 calculation such as an alternative coin's blockchain.

The first poster after the "press release" is part of the scam too, I'm guessing.

He's a noob who just HAPPENS to live right down the street from the supposed fab facility.

We can look forward to his next post, when he'll report that he visited their super secret factory and saw all the chip geniuses building prototypes or something.

These guys thought they were going to make like $5 million on this scam.  Let's see if we can keep that close to zero.

Who you calling a noob you 4 post having idiot.

Learn your place before you start accusing people of sh!t. I have been a member of this forum for almost a year. Just by coincidence I do happen to live just down the road from their "facility" and yes I was the first to reply. Wow.

Sometimes I wonder why I even visit these forums its like visiting the land of the trolls.

Rebecca, don't worry you are not the first definitely not the last company to come under the rigorous scrutiny of this great forum. Don't take it personally, as you are probably aware there have been MANY scams run through these forums, which has got a lot of peoples backs up. As you have read some aspects of your business have thrown up some red flags but hopefully, if you are who you say you are we can get these all ironed out.  I am really hoping you guys are legit as I am eager to do business  Wink



here is why you were called a newb:

The forums says you are.

Oh well done genius. Thanks for pointing that out. Wasn't aware that I'd even asked WHY he called me a noob  Roll Eyes

I don't think charging a % fee is really a secret. That's being honest about charging your customer.

The real secret of extracting the value of someones Bitcoins is with an arbitrage scam via delayed payment/delivery.
Or secretly merge mining an alt coin all for yourself is another one.
