I will be making some s9 space heaters.

Thanks for the update.  Like ok sitting in the same room with your quiet?

Thanks for the update.  Like ok sitting in the same room with your quiet?

Man  right now I am running two 2 board units. 892 watts.  and 10.3 th.  that is with volts at


8 and freq at 380 0 hardware errors.

fans are at 2100 rpm + 2100 rpm on the loud one  

the other one fans are at

1260 rpm and 1800 rpm.

really quiet.

Now to be fair the psi is a corsair 1500 watt titanium  so that 892 watt reading may be  910 on a aw3++

I realized if I do them with 2 active boards and the low noise fans.

I can include the old loud fans in case of a price spike  these can become a louder more powerful miner.

so  they range from

 a low of 450 watts and  5.15 th  

 to 800 watts and 9 th you must swap fans to go fast.

This is a nice project. So far so good.

Had to use braiins +  could not get bitmain firmware to play nice.


Did FIRST VIDEO  youtube it is  flooded with users so it will take 1 hour to up load it.

Looking forward to the video.  So to confirm, these units have a low power and high power mode but to achieve proper cooling in high power mode the fans have to be swapped out?

I personally would want the lower power and hash rate for less sound.  But good to have the option to make this more of a work horse.  

EDIT:  Just watched the video.  Thanks for putting it together!  Certainly interested in using these for mining and as supplemental electric heat.

video is up.


you can control volts and freq for both board.

8 volts and freq 380 is nice

8 volts and freq 410 is nice may be the highest you can do the freq at the 8 volt setting.


volts can be as low as 8.0

all the way to 9.40   by 0.1

ie

8.0
8.1
8.2
8.3
8.4


I would switch the fans with volts from 8.5 to 9.4
8.5
8.6
8.7
8.8
8.9
9.0
9.1
9.2
9.3
9.4


freq goes from 200 to 900

anything above 500 will need a better fan.

I will play with these over weekend and have some ready by Monday.

I am now testing volts at 8 and freq at 330

I get 410 watts and 4.7 th about 87 watts a th.


Working low end settings.

8 volts freq of 320 2 boards  gives me 4.5 th at 390 watts that is 86 watts a th.   fans set flat to 55%  1620 rpm 

temps are
board     chip
67.75   75.83
68.50    75.63


these are really good numbers.

db in video was 57 now 52.

if you consider posting to uk please, I am interested in 2 low power (400w) low noise units.

[philipma1957]

if you consider posting to uk please, I am interested in 2 low power (400w) low noise units.

I have 3 built I have enough fans on hand to do 6.

these can be set from 4th to 6th

and do about 340 watts at 4th = 85 watts a th

to about 520 watts at 6th = 86 watts a th.

I will have the six built by Monday.

I would ship to you ,but shipping is high, maybe 110 usd.  2 units would be about 140 plus 110 = 250 usd.

You will need your own psu's as shipping makes it not practical.

Once I have the six all setup I will demo them on you tube.

yeah i am happy with that, pm me when ready to deal.

are they switchable user end or you set them first before shipping? I would only use them on 4th setting.

Shoot me a pm I will program them with your pool and set them to about  4th.

They can be altered

the fans can do 1000 rpm to 2800 rpm

the freq can go as low as 200 as high as 900

volts can do 8 to 9.4

Since I made these to be quiet with slower fans.

 I suggest never setting volts higher then 8.4
 I suggest never setting freq higher then 440.

Your gear will be set to about volts 8.2
frequency to about 350
fans at 1200 about 40% on manual

giving around 350 watts and 4th.   for each unit.

shoot me a pm I will setup the pool for you on each one and test mine for you.

They like Firefox browser on windows.

They can do Firefox on Mac
they can do safari on Mac.

I also can access them with iPad with safari.

I seem to have trouble with edge browser and chrome when I use windows 10.

I downloaded braiins +  from braiins website to an sd card boot the s9 then loaded the sd card onto the s9 so they run without an sd card.



After weekend testing I am happy I have stable units.

[philipma1957]

Alright, I'm a bit slow, so using brains and undervolting how low were you able to get the wattage of a single board unit? Are you still planning on doing single board units? My use case is a lot less space heater and a lot more cheap desk piece cksolo pool.

I have the original 1 board unit built months ago.

I can hook it up today and go to 2th, 2.5th, 3th  and see what it does. for each setting.

I will sell the 1 board unit to you. I am pretty sure I can get it to do 200 watts and say 2.2th lets find out.  I will post back later today.

it is set to volts 8.2
and freq 350
fans are 40%. about 1200 rpm

this uses 225 watts and gives 2.5th   about 90 watts a th.

Thanks man, I'm looking forward to it.

first test is right here.

it is set to volts 8.2
and freq 350
fans are 40%. about 1200 rpm

this uses 225 watts and gives 2.4 to 2.5th   about 90 watts a th.

part of the efficiency being at 90 watts vs 83-85 is 2 fans and controller use 30 watts so a low set board 2.5th does not make up for the fans and controller.

Going to lower the freq to 325 and  will have results soon.

[TheYankeesWin!]

so you have 1 one board model?

and you have 5 two board models?

what are max watts and max hash for the 1 board
what are min watts and min hash for the 1 board


what are max watts and max hash for the 2 board

what are min watts and min hash for the 2 board

[philipma1957]

Just tested max settings for the 1 board

freq 515

I have been using  Parallelminer PSUs for 110VAC to 220VAC for all home use projects, here is a link:  
https://bit.ly/2TtvdOR

I think they will be better(more industrial) than the PSUs you are using.  Just trying to help out.

Here is a setup for a S9 for reference:



This one may be good for your heater:



This one may be large enough for your heater:

So funny you should mention this..

 I can run 2 x 2 board units but it gets the fan in the psu a bit louder.

It does run 1x 2 board unit perfectly go for about 4.75th. use about 400 watts


I just got 3 of these psu's in house seller's company is under 5 miles from my house.


https://www.ebay.com/itm/HP-643956-201-1200W-HSTNS-PL30-Platinum-Plus-Hot-Plug-Power-Supply-643933-101/312798058602?



I have sent one to kingcolex with a breakout board and wires it is not heavy to ship to USA

I found 3 breakout boards.

so I now have 3 of these psu's blue plug jack style means more efficient then black plug.   say 397 watts vs 415 watts for black plug style

[vickersja]

Cant wait for the 2 boarders to be ready!

Phil, will you be making any more single board units or are the dual boards more efficient/quiet?

[philipma1957]

Phil, will you be making any more single board units or are the dual boards more efficient/quiet?

I am not going to do any more  1 boarders.


I have two boarders ready. Five of them tested and can ship on Tuesday.

The two board can go to about 280 watts low end setting

and to about 500 watts high end setting with the quiet fans.

Two of them can range from 560 to 1000 watts.


They are a bit more efficient  then the one board. say 85 watts vs 90 watts a th

Shoot me a pm if you want 1 or 2 of them.

Since you are in USA

 I can do

About 190-210 for 2 units with 2 psu's

About 170-190 for 2 units with 1 psu  please note if you do this and hook both units up to 1 psu you can still use 120 volts but you would want to go lower speed as the psu's on 120 volts prefer to stay at 700 watts or less. So you would need to set to about 4th each unit and use 700 watts


About 150-170 for  2 units and no psu.

I forgot if you are west coast or near me in Howell,NJ. thus. the price range of 20 bucks is for more shipping cost to west coast.


Note the psu's will only be available to USA buyers. 






Shipping to Europe is hard to do and they break balls on psu's along  with the extra cost to ship makes the psu's only USA
I needed to write 7 emails to get some gear into Spain due to psu safety rules and price of the gear.
They wanted exact proof of price .

I can ship the modded s9's as modified non working servers for testing and repair if I send to Europe.

Technically since there is no psu in the box they are not working gear  and they really do need testing and "repair".

[vickersja]

Thanks!  Just sent a PM.  Ill take 2 with the PSU's

Can you share the voltage and proper settings for the best/max with the quiet fans?  I think you mentioned customizable voltage in a previous post.

Yes I will set it all up and test run it over the weekend then ship on Tuesday. due to holidays.

 Please send me btc

200 usd worth to

Send me a pm.  and give me a btc addy to mine to on solo.ckpool

I will get this set up asap

please send me payment details and give me the btc addy to mine to>

If it hits it would be cool.

I will show the screen shots of the 2 units test running.

THIS unit below would be yours.

volts are        8.05
freq is           300
fans set to 60%  that gives a steady 1860 to 1960 rpm
watt meter says  360 watts

hash rate =  4.273

360/4.273 = 84.24 watts a th   but it will flux.  since hash rate drops to 4th and jumps to 4.5th  as hashrate does flux so you can run from 79 to 87 watts a th at this setting.

Okay I got paid  I am running 1 unit over night for

vickersja

will run second for him tommorow.

I will ship him two  2 board miners and 2 psu's on Tuesday via fedex I think.  I like to use fedex the clerk is hot.

I have three 2 board miner's left  
you can go as low as 280-290 watts
as high as 500 watts for these miners

If you are in USA and want a psu let me know.

they are about 70 plus shipping  without psu.
they are about 90 plus shipping with psu.



3 miners as heaters left.
only 2 psu's
