Redesigned Dell 750W board, mostly done, reversion prototype needed
Redesigned DPS800/HPCS board, mostly done, initial prototype needed
New version Compac, initial prototype testing
Different new version Compac, initial design
Larger-scale miner board for S1/3/5 chassis, concept design
Molex adapter board for powered risers, first manufacturing batch needed
ATX24 adapter board for motherboards (GPU rig, etc), initial design
High power 7-port USB hub (6-24VDC, per-port current limiting adjustable to 3A), initial design
Can't say much about miners yet, but the rest are pretty cool.
If I actively took on that many projects at one time, I would come home one day to find my stuff on the curb. I need a good work space. Something with electricity and HVAC that is also big and detached from the house would do nicely. Redesigned DPS800/HPCS board, mostly done, initial prototype needed

FIAT (that I honestly do not know what else to do with)
Boy I wish I had that problem. Right now I'm in the middle of eight practically-unfunded design projects.Listing those projects could probably solve that problem.

How silent are they asking those that bought it and have it, 52 db to me is not that silent.
It's silent if you compare it to anything in the same ballpark performance wise, but the machine has it's special quirks.
1) You cannot force the fan lower than 1200 rpm, if you use a low-noise 4-pin cable the controller will stop mining. This is really unfortunate as it would be completely silent at 800 rpm and still give ~4TH@300MHz!
2) The fan has irregular oscillations in speed/noise which are annoying to listen to. This is due to the low speed I'm running mine at and the fact that the fan roll is large and heavy.
That said at high speeds it's noisy but VERY silent compared to anything moving the same amount of air. Basically it doesn't become louder when you spin it up, only the air blow noise gets louder and that's hard to avoid.
All in all I'm very happy to exchange FIAT (that I honestly do not know what else to do with) for something that converts FIAT to BTC without KYC while heating for "free".
Mostly I'll use this to maintain temperature during winter while I'm away, and then I'll heat with wood which is a sound I prefer to listen to.
Edit: Variations can be reduced by the old classic "reduce vibrations through support" method. Fire hazard is better than bad vibes.

for one it cost that wow
i also wonder how much they skim off shipping for there self most shipping is not that much, I know what they charge us to ship,I know they have to declare what they post to keep it legal , but how much is the real cost .whats there shipping discount we don't see and they don't pass on to us.
Just like Infomercial products, the S&H is where good money is to be made. Most of the backers of companies you see on-TV own the distribution end of the business and get all the "& Handling" part of +S&H right off of the top.

R4's no longer shipping free i was wondering how long they would let that ride sigh ....!!!
The shipping cost is not included in the retail price shown above. Please fill your desired quantity, shipping address and select your preferred shipping service while placing an order to learn the exact shipping cost.
Guess they see they can get a way with selling it @ 1395.00 plus shipping .
no one should really complain either if you buy it ).

R4 is back on sale but same 1395 price. I would like buy but price is insane ROI 1 year or something, warranty 90days and they don't seem to honor even that, mining GAMBLE.
Funny how it came back on sale once btc price dropped. I would get one with a better warranty but since I killed 2 of 18 s-9 boards while running them on a down clock the 90 warranty simple does not work for me.
My first 2 s-9's lose their warranty in 2 days.
My second set of 2 s-9's lost their warranty in under 2 weeks.
My fifth s-9 has 50 days on warranty.
I can not afford an r4 with a 90 day warranty.
So since I mine I will get one more gpu to mine more ETH to sell for BTC.
My 22 gpus and all the rest of the pc gear have 2 year warranties. Bitmaintech's warranty policy makes it very hard for me to buy from them.
Avalon comes out with the model 7 if they simply give a 6 month warranty and does service for it they could compete very well.
Seeing a new Avalon offering anytime soon seems as likely as a watching purple unicorn do backflips while riding a motorcycle.

Good afternoon. My question to Antminer R4 offer power supply
APW5, 1300W-2600W PSU instead buy APW3 + -12-1600 PSU will work? And What of them more than noise?
APW5, 1300W-2600W PSU instead buy APW3 + -12-1600 PSU will work? And What of them more than noise?
While I have owned neither of these, I think I can comment on a couple of items:
For the APW3 (1600W) power supply to work you MUST supply it at least 208V or it won't even start. If all you have is 120V (common USA outlet), then the AWP3 noise doesn't matter since you can't us it.
My impression, though no direct experience, is that the AWP3 isn't a very quiet power supply. I am sure there are others that can comment from experience, but I expect the AWP3 might well be noisier than the R4 miner itself. The form factor, and small cooling fans (i.e. high RPM), usually result in a fairly loud power supply.
I expect that the two items above are what led Bitmain to produce the AWP5.
Perhaps the APW 3+ different from APW 3 low noise level, or
there are other differences? I did not find.

Remember when they jacked up the S5 price about 20% in one day because they got some inside information on a competitor not coming to market?
I agree with you !
Avalon must coming out real soon.
And they do it on Sept 7 ?
