New s9 upgrade thread. Some info is 🆙❤⚡

[philipma1957]

The newest design has a spacer .  It is why I have been getting away with the 3000 rpm fans.

I use 4 things
Some 2 by 4 wood
some silicone epoxy
some metal tape
some screws

I cut 3 pieces of 2 by 4 into trapezoids
I silicone them into 1 piece
I wrap them with metal tape
I put them into an s9 shell.

You can use wood glue or silicone epoxy





here is a you tube of assemble with silicone epoxy. it is in 3 parts.

At this point I am going to run 2 1 board units over night.

They are fully built and I will be test and comparing them for 3-4 nights.

In 5 nights I will be running a third unit with 1 board and really good fans hi end long life fans from san ace.

made of metal not plastic.  they are 4700 rpm fans and fairly quiet.

So I should have 3 comparison units. fully tested by next weekend.

Very interesting thread, Phil. Great idea for space heaters with decent efficiency.
Please let me know when you have dashboards available for sale or if they can be purchased from the "mystery builder".

[philipma1957]

I asked for pricing on :

   10
   50
 100
 500

boards.

Mostly depends on what he or she tells me for price.

These make

quiet one board 290-320 watts about 5.5 th

yeah you can do a two board but so far I can’t get them to be quiet as  I like.

and of course you can do a three board but fan speeds on low setting make them pretty loud.

So far simply set to low speed and let it tune for a day.

after 15-16 hours it locks in and does not reboot much.

I will be getting a covid-19 antibody test tomorrow. As will my wife.

we finally have them available to take.

I am hoping they find antibodies in both of us.

we were both really sick in Mid Jan.  I fully recovered,but my wife seems to have damaged her sinuses as she is now on month five of a post nasal drip. Simply can not stop 🛑 it.

Good news for her is the O2 meter we got read 96,97,98 % and even 99%

when she got out of hospital 🏥 it read  91,92,93%. so what ever the double pneumonia did to her lungs is healed. her temps are 96-97.9 last 70 days and her pulse is 67-78. unless she had a cough fit from the endless post nasal drip.

we will be going to more doctors for her once we get the test result.

This is all not off topic even though it seems to be.  I and my wife have been spending tons of time with different treatments and studying many pages of info on meds and treatments. So it slows my btc work.

covid-19 and now the protests and riots have slowed me up a lot this year.

[ATCkit2]

Yes- we live in crazy times. However, we did survive the 70s... when we all felt tomorrow could be the day the nukes are unleashed. I think most of us will get through this too. I'm sorry to hear your wife has had such a hard time. Nice to see her O2 back to a normal range. My wife had a double lung transplant last fall.  We all forget how vital this organ is.

Nice to hear you have the antibodies test available there. After such a rough Winter, I hope they find antibodies in both of you. The next thing is "how long will the antibodies last"? I know they're collecting data on that. Hopefully, they last at least until a vaccine is available.

[philipma1957]

We just got back from blood🩸 drawing.

Results on Friday.

If we show positive antibodies we will look to see a few ear 👂 nose 👃 throat doctors.

Years ago I had my nose 👃 cauterized due to endless post nasal drip 💧.

It worked pretty well.

I will also be able to go back and forth to Clifton and work on the mining farm more.

I am talking about getting a large board order for these boards.
I hope to get a reply today.

Depending on deal offer and time line I may ask for pre order money 💵 but I really don’t want to do that.

Ideal would be an order of 750usd worth of boards.
Get the boards.
Then another order of 750 usd worth of boards
get the boards
then another order of 750 usd worth of boards.

No news on boards but china is locking down sections again.

Note: this is from another post of mine

https://bitcointalk.org/index.php?topic=5256466.msg54642018#msg54642018

left wing source: https://www.cnn.com/2020/06/15/asia/coronavirus-beijing-outbreak-intl-hnk/index.html

right wing source: https://www.fox5dc.com/news/more-than-100-million-people-in-china-face-new-lockdown-as-second-wave-of-covid-19-cases-emerge

So I am guessing it is real since both left and right say it is.

To all don't order from China for a few weeks. ... "

I got the high quality $50 usd a piece  fans I got them used for $14 each.

They are so good you only need one like an older Avalon
I also redesigned them yet again and look at the cooling



only 3 hardware errors



I have another fan on order I will build the unit with that and test. I will also do a movie today.

[MoparMiningLLC]

can you share where you got the fans - I would like to have some back ups and better fans are always better - I assume they will work on all the antminers?

[philipma1957]

This is the video I just made.

https://youtu.be/6niZ_J37x1U

maybe have to think about it.  they need to be spliced as they come cut.

check video.

[MoparMiningLLC]

wish you had shown the temps of the other one with the  better fan.

[philipma1957]

Battery died it is charging.

I have come to the conclusion that the 120mm x 25mm 3000 rpm delta's are not good enough.

The better fan does work well it is all metal 120mm x 38mm. 4900 rpm A guy on eBay has 10 or more to sell.

I can set the gear to normal speed in a warm room. 85f

lock the fan in at 50% minimum and it does the job

Here are current settings 'normal'

takes an hour to tune somewhat

room is getting too warm 86f

https://i.imgur.com/cZkoA47.png

I am going to eat lunch

I will show temps
I will show hash rate
I will make YouTube

2-3 hours


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

That is the better fans running as a pair I can go to highest speed with no issue.

To update.

I liked these boards and made inquires into purchase of

  10
  50
100
500

boards.

It has been more then 2 weeks since I asked so I have decided he may have no interest in selling to me.

After much testing I did discover a 1 fan push worked best for cooling and saved more power.

Kind of like the older avalons.

I was able to get very good numbers at normal speed. which is a freq of 510

I did 6.1th and used 340 watts  this is 55 watts a th

since the builder has not offer these to me in bulk and i have 3 boards in 3 separate units I will most likely use them to space heat the house this winter.

[qctechno_isback]

I love the numbers, perfect small space heater with good efficiency ( not cutting edge but super respectable ). I'm seasonal miner now, quiet space heater is huge market IMO. Lot's of friends wanna mine and heat but can't handle a 3KW+ beast mode miner.

I'm following your thread closely, waiting for price per board.

[philipma1957]

And a  new update.

I was replied to on June 16th it went to my spam folder.

My bad.

They told me they have a 600 board minimum. I replied today letting them know I could be interested in a 600 board shipment.

Details are pay 1/2 up front

3-5 weeks to set up the assembly

1 week to make the 600 boards.

So In theory if I pull the trigger I could get them 6 weeks from now.

Frankly I do not need 600 for myself.

I could do with 60 to 100 for myself.

I will see what price with shipping to New Jersey , USA   will cost for 600 boards.

I will post back when I get a reply.
I will check my spam folder a lot more closely  

[gt_addict]

Are you thinking of selling the additional boards on? Would you be selling just the boards or complete "plug and play" units Phillip?

[philipma1957]

Well frankly 600 boards would be 200 to 600 miners depends on the  boards per unit.

I have 28-29 shells. So even if I build 28 miners to use at the Clifton ware house that is 28 x 3 = 84 boards

so I only need 84-100 boards.

Assuming the offer for 600 boards is a decent price.

I would have 500 boards to sell.

I am not going to source s9 shells 🐚 with controllers and fans.

I would need to be able to sell 500 boards. I am not sure of the demand for that many boards.

Remember while these are pretty good doing 55 watts a th. they are not super good. say 35-40 watts a th.

Now I will wait and see what he wants to charge me for the order of 600 boards.
Lets say I like the price.
I need to see what can be done to ensure delivery 🚚  of the gear.
I need to see if someone wants boards.

[wndsnb]

Well if the price is good enough I'm sure there would be a lot of people who would like to convert their S9 paperweights into something useful. Break-even for 55W/Th is about 5.6c/kWh. Could work if the price is around $60 per board. Of course if BTC tanks you'd be left holding the bag unless you got commitments before ordering.

Well we can forget about this project.  I just got pricing for 118 a board.

Even if I go  with custom 2 board  build designed for quiet. 

 Parts would 2x 118 = 236

Shells are 30-40.    =  276

Newer fans            =   14
A few other parts.  =   10

a grand total of     $300 for a 2 board that does 10-12-14th. and uses 550-660-770 watts

  This is my cost to build it.  So even If I restrict to USA only.  it is 30 to ship

330 cost at zero profit for me.   Not going to work.

[MoparMiningLLC]

yea they are wanting too much per board. good job on the work you did but yea I dont blame ya for not going in on 600 boards at that price.

[gt_addict]

Yep thats not worth doing. You need to be making something for all the time and effort in building the things.

[mikeywith]

If we ignore the noise, and use 3 boards instead of 2, total cost will be

3*118 =  $354

so 21th at 55w/th  for $354  or 42th at $708, that is like buying a T17 42th for $708, now if someone has a dead S9 that is worth nothing and APW3/7 that sitting there doing nothing, this might be not to bad a deal, for the following reasons

1- T17 quality sucks
2- T17 Requires 220v while these can work with 110v and don't need a stable voltage
3- The cost of power supply on T17 is about $200, while a used APW3/7 can go for as low as $10
4- If you lose 1 board on a T17 that's about $200 gone, and only 50% of that if you lose one of these boards

With that being said, given the efforts, it might still not worth $118, my initial thought was 60-65$, given the lack of gears supply nowadays I think they will do just fine with about $75-80.

[MoparMiningLLC]

... given the lack of gears supply nowadays I think they will do just fine with about $75-80.

agreed with this - at that price, I would fit the two shells I have and put the psu's to use. right now they are just gathering dust.

[philipma1957]

Can’t do 600 x 118 =  70800. and I may get stuck paying 18000 import tax.

yeah they need to be three board .
set to normal
about 1150 watts and 20th.
