I have also ordered one of these and live in a two room appartment so anything you come up with on the watercooling front would be very interesting

umm.. u can already do that. If you set api-allow setting to your computers ip, you can use all the cgminer API things to monitor, manage pools, etc etc. https://github.com/ckolivas/cgminer/blob/master/API-README

Also since u can ssh as root into the device.. so that basically means u can do whatever u want remotely..

Check out the AVALON ASIC USERS THREAD.  Read all the pages.  You will be an expert.  The design difference between GEN1 & 2 is just a nano-meter shrink, everything stays pretty much the same.


Cool!  Mine hasn't shipped yet but was supposed to go out yesterday    


If you wanted naked asics should have bought ANTs    


Living with Avalons is like living in a datacenter.  As long as you don't mind the jet engine!  Watercooling and swapping to lower speed fans does help that...


Yep you can run Avalons off rPis... again its all in that master Avalon thread...  But the TP-link is just using cgminer what is required to run the API?


Good luck!  With the fan speeds and hardware errors reported in the original BTMine screenshots, I assumed from owning over a dozen Avalons in the past the system is already running pretty close to maximum.  The PCB already has been modified with "shortcut" wires to boost the core voltage (which is what the original watercoolers did to get great first gen boosts), but as this model already has all those mods I'm not sure watercooling will help much as you will start to toast the VRMs way before you hit the thermal limits of the actual chips with watercooling....

Read this watercooling thread:

And of course I know it will take a while to read and I already said it, but *really* everything you ever wanted to know is probably somewhere in here:

Remember stock Gen1 avalons came at 282mhz.  The design was good for OC until about 350mhz range.  Avalon added rear heatsinks to the minis and got 375mhz.  To get over that those shortcut/cheater wires were needed and watercoolers got 400-450mhz.  Now OC'ing a Gen2 will be a bit different, but with the massive heatsinks and cheater wires included, I do theorize those BTMine units are already being sold near their maximum limit.  Just my $0.02, if you get around to modding please update this thread and let us know!

There are plenty of these things out in the wild.  I'm sure someone has had to have done something esp. at hosting facilities.

I've been kicking around the idea of making some changes and the search availability time takes forever and so far have not found anything.

Currently I have one here and 5 more of the BTMiner v1 units on the way.  I also have another off-brand single PSU version.

I have got watercooling kits coming for all of them (with the waterblock...  Not the pipe version).

So I have been pondering around with the idea of removing the cases #1 to save space and hopefully allow for extra fans to be added easier to pull the excess heat off.

Has anyone done anything like this that could give me some pointers?  I have a 5000 sqft shop we work on our cars out and part of it is a "living area" with TV, couches, computers, etc...  So I am hosting their remotely.  Which brings me to the next question.

Is there anyway to remove the TP-Link portion (so remove OpenWRT period) and run something like rPI or BB Black so I can configure the miners to have open API's and allow me to remotely watch them all in one monitor.  The built in software is good but very limited.  Which is where the idea of changing that came up. 

If anyone has done any other mods other than overclocking that would be interested in giving me some tips on this.

Thanks!
Chris
