and lastly the .61 amp setting does give hw  errors but not to many.

 i may tweak it to .62 or .63 amps looking for a little less on hw's

read the thread all answers are here.  Does not that seem fair to write.

here is break down

  total of   36 watts for   the  entire setup  I don't count the monitor as it is turned off 23 of 24 hours

----------------------------watts

1)pc --------------------23-25
2)usb hub -------------  4-5
3)fan -------------------   1
4)usb meter -----------   1

5)1  stick --------------  3

The pc runs a full node and uses 23 watts idle 25 watts on a node

A rasp pi would do 10 watts idle and no node. So since I choose a real pc my penalty is 13-15 watts over a rasp pi, cubie, bugle bone etc

I am just waiting for a chance to pop in more sticks to see practical limits for sticks  + boards.

 it will be too noisy .  

buy this fan:

buy a used s-3

this psu  but some one may find better for you.

My cost for you is under 200 and you will most likely lose money. due to your cost of power.

At the op no gear for sale will profit for your kwatt cost. (I am pretty sure not certain this is true.)

Since you are going to lose money in most cases buy a used antminer s-3  for 85 usd buy a silverstone 141 mm fan for 16 bucks

get a small quiet psu .  and then run the s-3 in balance.


I would then run the s-3 in balance I will show  you what I mean.
see this post

https://bitcointalk.org/index.php?topic=763510.msg11617555#msg11617555

a screen shot that shows how the s-3 splits hash to 3 spots 140gh each 2 earn a little money 1 could win a block.

this will run quiet use under 400 watts and cost under 200 usd .  most likely you will lose money

of course it does and I want one. but so many parts with so much gear in house  and a very patient wife .

I don't want to add any straws at the moment.

Today the usb meter came an intel cpu came. some fan grills are due. some more parts tomorrow.

I have to build a pc in the next 2 days.

z97 asrock itx mobo
i5 4570t cpu
2 8gb sticks of ram
1 250gb msata
fsp plat 450watt psu
a silent zalman cpu cooler

s much as I would like the meter no more gear for a week or two. (or not and I will say fuck it and ask you for a link to buy the meter)

I would use plywood same size as the opening  say 24 by 24

I would cut a hole for exhaust  and mount an exhaust fan only in the window.

I would open the inside door and allow in air that way.

yeah but the oven temp meter is pretty good. cost = $0



I have also decided to  bump amps to 0.61-0.62   vs 0.6


reason is at 0.6 HW is 2%  at 0.61-0.62 HW is under 1%

so my stick seems very happy at freq 175 and 0.61-0.62 amps  still is that nice 0.31 watt per gh number.

with the fan blowing on it no worries.  I think I will turn the fan off for an hour. I don't have an infrared gun but I have a temp for food which if placed on the heatsink should give a good number.

27c with fan turned on

40c with fan turned off

went from 27 to 32 c with fan turned off


moved up to 38c



it is hard to read but 39.6c and I played with lowest amp setting here at 0.57 amps = constant hw's



fan drops it down fast to 28c this is in a 25c room temp   notice amps at 0.61 this is much better for HW's


lastly look at HW they are at 698

and the new usb stick meter came to me today photos posted

it looks like the stick I have can do freq 175 at 9.5 gh and 2.94 watts at worst that is 0.3094 watts a gh.

maybe does 9.65 gh  which is 2.94/9.65 = 0.3046 watts a gh

 I am using poolside gh and cgminer gh

so the gh varies from 9.50 to 9.65  watts needed for that is 2.94 which is amazing

now I had a good  meter for 1 stick  so I dialed back power  the pot is  now  in this position  


+   in stead of ⅛ clock wise     the readings dropped from .66 amp to .6 amp

 so .66 amp x 4.91 v =  3.24 watts  and 9.5 gh


now .6 amp x 4.91 volt = 2.94 watts and 9.5gh hash

or 3.24/9.5 = .341 watts a gh

2.94/9.5 = .309 watts a gh


.309 watts a gh at freq 175 is really good and most likely accurate within 5%

amazon meter arrived. some photos

meter looks nice and it flips stick so tweaking stick is easy



close up


and we are pullin 9.5 gh or so

I pm'd a pledge for support.  

I would be looking to buy sticks and 18 chip boards down the road. I don't mind leaving some funds in sidehack's hands.

pm sent.

my bad you are correct.

Yeah that link will get you to melt the power input port or wire.

Frankly I love the rasp pi but it has its limits ie use a powered hub.

My guess is  7 -10  sticks will run on the older pi model b with 0 issues.

The upper stick limit will be found on all rasp pi's.

hey if you have a good hub .

the hub will power the pi and run sticks.  I am pretty sure this hub will power a rasp pi  and plug into the same rasp pi allowing up to 7-10 sticks .



 I also think
not so sure this would run the rasp pi and 40 plus sticks.

 

yeah best way to keep a wallet safe is dedicate a pc to the blockchain and nothing else.

I use an old mobo/cpu from gpu mining back in 2012 .  I run my wallet on that and nothing else.

you need to tell us more about the window.  does it slide left right ,

does it open up down?

can you do a little on left and right?

can you do a little on top and bottom?

If not you have problems. fixing will be tough

well I knew I had enough parts to rebuild 2 pc's both with low watt intel t cpu's

so if you are building a 'free' pc that idles at 23 watts and runs a node at 25 watts


vs a rasp pi the uses 10 watts.

 cost me 0 either way


  you have to ask yourself  for 15 watts  or 11 kwatts a month extra or 2 bucks a month 24 a year .

what is better to run sidehack's gear.

I would be willing to say the pc build will allow me 20-25 sticks using the 2 stud hubs I own.

I would be willing to say the pc build will allow me 8 to 10  18 chip boards.

 I think the rasp pi won't do that.   So the node  is really a  2-3 watt gift to bitcoin on my part.


I am not sure how many sticks and or boards will come to me  as a user and as a kit seller.

We need to see how it unfolds.

But picture a  small pc built to run cgminer / bitcoin node doing 25 sticks + 10 boards.

vs a rasp pi bogging down at 10 sticks and  or 4 boards .

Remember this is All conjecture since no one has run  more then 5 sticks on  1 hub.

So no one knows if that is an issue for rasp pi's or cubies or beagle bones or is that bugle bones.

So my 'free' pc build  may drop the node  if I determine the node lowers my sticks and or boards hashing.

This is the fun part of the gear testing limits figuring what's a good setup etc.

Time will tell.

no  I have it set at freq 206 and I get a total of 420gh pretty much between the 3

Family First man.  I am sorry for your loss.  I will continue to post in the review thread.

Maybe we finally go over 50 bill this time.

The  picks start in another   250    blocks or so.


 300 made --- 1716 left to be exact


we are at

48 made ----- 1958 left


I think block 360874 was the starting point for this adjustment

we are at block 360922

we made 48 blocks in 9 hours 22 minutes should make 6 x 9 = 54 + 2 = 56 blocks

So we are off slowly maybe - 8 on the first day.

Would be funny if we drop -3 to -5 % this time and keep under the 50 bill mark.
