I will be making some s9 space heaters.

[philipma1957]

I will be shutting down 28 s9 units come the 1/2 ing.

I will be converting a few to one board space heaters.

you get

one board
one s9 square tube
one controller.

some mods for silence.

one board means 300 to 400 watts of power.

these are not to be thought of as miners first.

think of them as a space heater first.

point to what ever pool you want.

they are not designed to roi.
they are designed to provide heat. and will cost less to run vs a space heater.

no psu. you need a psu for them.

They will be a available  in june.

prefect time for a space heater.  


I prefer to ship to USA.

I will link my design thread later today.

This is not a preorder. More like an interested buyer order.

When I take in funds the gear will be in my house ready to ship.

This is more or less what is a quiet 330 watt 4 th miner worth to you.

Keep it, maybe the btc price will rise to 10000usd soon.

looking forward to seeing the designs

Thanks!  Would these come fully assembled and just need the PSU or require assembly?  I would be interested in trying one during the summer months for solo mining.  We have electric heat and use my R4's now but 2 of these running would produce the similar TH/s for lower wattage.

they would be add a psu.

I would clock them to about 4th and about 320-360 watts depends on your psu quality.

Alt account? 

Add me to the interested list. 

[philipma1957]

YEAH it is an alt.I was out which almost never happens anymore due to coved-19 lockdown.

note always check the profile when I talk with you via pm.

It will show









I will try to build about 10 of them.  We are talking a may 20 ship date.



 Unless of course BTC moons and I can still mine them at full power after the ½ ing

[vickersja]

Got it, thanks.

How much for 2 of them?  I would like to use the Bitmain APW3++ - 1 PSU for 2 units.

Not sure as The most important part is finding fans..

If I can get a good price on fans say 8 or less. I can make them cheaper.

by having buyer provide psu they are cheaper and you save on shipping.

also 1 board vs three boards cuts weight.



I just ordered 10 fans which will do 5 of these.

 paid 66 for the 10              = 13.20 in parts per unit.
 foam is 15 does 5              =   3.00 in parts per unit.
some stainless steel screws =   0.30 in parts per unit.

so 16.50 in parts I would like to tack on 8.50 bucks profit = 25.00  plus shipping for a setup 1 board space heater.  

that is a lowball price as I could just sell the s9 dirt cheap for more then 25 maybe 60 on ebay.

I don't know how to find the right price as 25 is too low and is giving a zero value for the case, the hashboard, the controller

I think I may try selling it for 40-50 and giving a spare hash board not inside the modded case which will only fit one board.

 Also this would really be difficult to decide on correct price since I am selling it more to space heat. And you don't have to do labor to mod the s9 your self.

Once I get shipping info from seller  a Chinese seller I will have an idea of when I get them {10 fans} . And when I can ship to buyers here.

I also have a pricing issue if these become viable miners again.

 Ie BTC moons before I take in money and ship.

 I am thinking 40-50 bucks plus shipping
 you get the  1 board mod with a spare board and you need to supply the psu.

I think I would sell at that price unless BTC moons up a lot. 10,000 and I would ask for more.

[vickersja]

Appreciate it!  May take 3 for the initial order.  BTW - I got the moonlander.  Thanks!

[philipma1957]

I am interested as well, how loud are we expecting? Not exactly thinking as a space heater but more as a gekkoscience style desk miner myself.

I have to go back and look at the build thread maybe 45db with an atx psu.

I will use bitmain software july 2019 set to lowest power it does 3300 th.

I will cherry pick boards .

I will cherry pick boards .

I haven't owned a Sha asic since  the S5, if you plug in one of three pcie could you run a partial amount of the chips? I do remember that they were chained, so I am not sure if this is possible. Would be cool to run one at 100w (at 1/3rd the hashrate)

1 board set to -2th is the lowest on bitmain firmware I was going to use.

I think you could go lower with braiins maybe 2.7th

I have nothing to do I can play around remotely today and see the lowest board I can find. Then when I go to Clifton at. the farm the units are numbered I will know which one to pick.  this is s9 ACG it specs well on lowest setting 2 boards match out well.

this drops to freq 470 and about 3300 a board on lowest setting.
once mod is done fans will be at around 3000 rpm.  I would build it for one board and send a second board with it. the mod will not allow for a second board.  this will pull about 300 watts. depends on the atx psu you use.





here is the one I built last summer-fall
note fans are under 3000 rpm they won't go past 3000 and thus are pretty quiet but of course you can only run 1 board.

[vickersja]

Would this unofficially be the most efficient 110V Antminer? 

[philipma1957]

Would this unofficially be the most efficient 110V Antminer?  

well if you are willing to go with aftermarket firmware it can go under 80 watts a th. so i guess that is a yes.

I won’t use anything but bitmain firmware. But if somebody wants to see how low it can go they are welcome to it.

I have been able to drop a braiins down to 82 watts a th.

since this uses lessor fans the fans will only pull about 10+10 = 20 watts at 2800 rpm.

stock fans pull. 25 + 25 = 50 watts at 5000rpm.

the chinese fan seller has claimed he shipped the 10 fans.

so i have 1 working model in clifton

i will be able to build 5 when the fans come.

so first batch will be six units.

the russians were building a passive radiator that does 65 watts a th. uses bit fury chips.


i saw the psu in it and it is a meanwell there is a 110 volt meanwell that would work. so i think they are more efficient.

[vickersja]

Funny you mention June.  We will be flirting with some record lows here in Alabama this weekend.  I could use those heaters..... in May.  Who would have thought.

yeah it got cold here in NJ.

the fans landed on the west coast yesterday maybe I get them by monday.

In theory a ship date for buyers could be friday the 15th.

i will have five or six first batch.

second batch will be five more.

goal is to sell maybe 20 .

[algcool]

Keep it, maybe the btc price will rise to 10000usd soon.

Already 10000usd now！！！！

[philipma1957]

Looks like I can use braiins and do 5.7 th at 499 watts stable and pretty quiet.

They will be set up to do 2 boards not one.

I have not been able to get the bitmain firmware to do what I wanted so I went with braiins plus.

















at 8.1 volts for each board and freq 410 here are numbers














old info below

Okay I got my first one setup to test.

Decided to use braiins plus and not bitmain firmware.

Although I have a few that can be bitmain.


it looks to be stable at 292 watts and 3.3th
very early numbers here show it just showing up on my pool. so it says 1.5 th I will post more info in the morning.

I hope to have 4-6 ready to ship on monday.
