Topic: I will be making some s9 space heaters. (Read 1407 times)

I got three test boards designed to fit in an s9

they do 5.3-5.5 a board at about 320 watts.

I may be able to get a lot of them.

since they are 52-55 watts a th they are not really cheap.

not sure if I can get 30 or 40 of them to make better 1 and 2 board gear.

i will post again

you can also look at hardware to see the test thread.



this is the newer better board thread.

I have zero idea if I get boards in bulk
I have zero idea if price will be good.

but I would buy 30 boards at correct price.

Sold 1 one board the original built months ago. shipped it out to Florida

 sold 6  two board units shipped out 2 to Alabama shipped out 2 to UK and I need to ship 2 back to Alabama Same customer. he like the first 2 units.



I have enough fans to build 4 more.

I have a psu or 2 on hand if you want a psu.

I am taking a break for the weekend I will build the other 4 on Monday and tues.


So if you want some let me know. As after these 4  I may halt production.

I am in discussion to do some mining farm work and may not have as much time after mid June.

Don't worry the next set of fans came from China which means I can build 5 more. I will ship you the two Tues and be ready to sell more to you next week.

They are nice lottery machines with added benefit with heating.

I will end up with lots of spare parts so I will be able to support these for quite a while



the braiins software is really nice.
Runs well on mac os  chrome safari or firefox.
on windows  10 it likes firefox.

FedEx should make that a commercial. 

I wanted to give others the chance to purchase, but if there are no other takers, consider them sold!

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

Awesome Thanks!  Sent via PM.  Looking forward to them. 

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.

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.

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".

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?

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.

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

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:

Just tested max settings for the 1 board

freq 515
volt  8.25

90% fan setting

1860 rpm on 1 fan
2760 rpm on 2nd fan

You would set that if there is a bull run.

trying a low setting test for the 1 board

50% fan setting

1020 rpm on 1 fan

https://i.imgur.com/ftlxf0B.png

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

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.

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.

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.

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.

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.

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