^^ All covered in the Avalon Troubleshooting & repair thread.

Tried changing the wall wart feeding the RasPi? Make sure it is rated at 2.5A or more so it has capacity to feed all UAC's and their strings.
Also, this really should be in the Avalon Troubleshooting & Repair thread...

Maybe.
There are 2 control methods, one is no signal on Blue = full speed which in my book is the safest, the other is no signal = lowest speed. Looking up the fan specs should say which they are.

I've never played with the fans so just cut the blue on one fan and see what it does, you can always splice the wire back together if it slows down. Beyond that setting min fan speed to 100%  - should - force them to always run full speed.

1st, Kudos for recycling your question into an existing thread! Keeps the relevant info easier to find.
As for front/rear speeds, even Bitmain can't seem to make up their mind. As a power systems designer, personally I'd put the faster fan on the intake side to provide higher pressure airflow in to overcome resistance from the turbulence all the little heat sinks make. What might change is the noise.

^^ and depending on the model and temps, s9 power draw can be as low as 1250W (s9 batch-1 uc to 550MHz producing 12.75THs)

The s9 default is using DHCP so you will need to look at the router for the address. Once in you can then set it to a static address. Routers generally use either the first address (.1) or the last one .254, at home mine is .254 while at work it is .1

Ideally both the router and laptop should be on the same subnet.

Depending on your power cost, not exactly a doorstop if you already have some or can buy reasonably cheap. They throttle down very nicely. Using -avalon7-voltage-level 12 combined with setting offset to -1 drops power to around 750-800W and still gives 6+TH. Also makes them a helluva lot quieter.

No, it won't for the same reason a refrigerator/cool does not work: Yes they all can get very cold but they do it by *slowly* removing the heat from inside the well insulated casing and what is stored inside. The food inside only has heat energy stored from when you put the food in and does not generate any additional heat.

In short, only air conditioning systems and fluid chillers are designed to continuously move large amounts of heat input - that is why they are so power hungry vs refrigerators/coolers/freezers.

That is better answered in the solo.ckpool.org thread. That direct link is spot on with your question.

and having deeper-lying Sanity Check routines to set hard limits to config values too far out of bounds reduce the chance of it. Same risks apply to owners of Avalons and BM miners as well - very few reports of folks breaking them via changes done through ssh.

Given how Halong has behaved from day-1, to me it's on-par with how they run things. Totally expected.

Kudos for them actually getting product out the door that mostly/does work. Jeers for their support and openness.

@ mhyde71
A. Stick miners are only useful on a solo pool and viewed as a 'lottery ticket' or if en-mass maybe ckpool. Any other pool will reject you as being far too small.
B. The miner can mine only coins using the SHA256D algorithm. That rules out about 90% of the (alt)coins you listed.

And that is the main problem. Folks are dealing with advanced high-power technical devices and if they are going to experiment then at least when it comes to supplying power and cooling for them they damn well better research the basic principals & guidelines behind what they are thinking of doing.

There are scads of sites dealing with wiring your home and giving tutorials on HVAC. Those are the first places I would check for info. Someone just saying 'it works' or 'doesn't work' does nothing to help a person understand the why behind the answers.

Getting back on-topic, I seem to be cursed to hover around 300THs... Was up to >309 then had 2x T9's go titsup in the main farm at work. Early last week I replaced them with 2x A841's. Now the internet at my GF's house is out again so her 2 A821's are offline until the 10th which is the soonest AT&T will be out to fix it putting me back to around 288-290THs  

narf...

The *sigh* is because at least 3-4x a month here and in other threads someone comes up with the same 'idea' of using a cooler. Would they ever think of using a cooler as a room air conditioner by leaving its door(s) open? Unlikely. Why? Because of their low BTU ratings it loses its cool rather fast before cooling off the room and yet the same thought never enters their minds when it comes to cooling miners...

I'll give an 'A' for them considering the idea but folks need to think things through a lot more...

Sigh...
For the umpteenth time: Folks, coolers for food/flowers/beer, whatnot are NOT designed to remove significant amounts of heat continuously! They can only move a little bit more heat than what leaks in through the insulation and whatever heat comes in with the food.

For reference, 1kw of power = 3415.179BTU/HR of heat to be moved. That is the numbers you need to look at for air-conditioning loads.

If you mean to export the Rewards data, just go to your Rewards page and select/copy the data. Then, open a new spreadsheet 10 columns wide x how many rows of data you selected and paste in the data. Not as quick as the page having an export to csv ot tsv function but still very simple to do.

The only ref I have to Luke being involved is jstefanop's post on p1:

And when you post the log(s) here, be sure to use the code icon # up top to paste the code into a scrollable window vs it being a wall of text.

Not sure but Slush is what stuck in my head at the time.
edit: Yer right. per https://en.bitcoin.it/wiki/Pooled_mining corrected post.

Of course it has a warranty. Um, perhaps check the MyRig site or email them support@myrig.com to file a support ticket?
Also, MyRig has an official support thread here you might want to use.
