If you look closely, those fans are facing with the airflow up and out. You can tell by seeing the crossbars that connect the fan motor to the housing which is usually on the outlet side.

So those are probably second fans with the factory default fans on the bottom.  They are situated the "right way".

Ya I was about to say they could have just flipped the fans

Fans are much less effective in suck position. You would have to make the tunnel over the heatsinks air tight.

They've gone from Suck to Blow?

Ludicrous Speed!!!

It's a good concern, but many people on here have built with wood. As far as I know, nobody has had a problem. The GPUs will stop functioning around 100c, well below the combustion point of wood:

http://www.engineeringtoolbox.com/fuels-ignition-temperatures-d_171.html



The GPU stops working at 100c, but the voltage running all through that wood frame don't give a damn.

I'd be more worried about that setup breaking and dropping 5 grand on top of another 5 grand of hardware before I was worried about fire, though.
yeah the crossbeams holding up $5000 in video cards is being supported by a small twig!

not that I can tell, here is what I get when starting cgminer, I would say no error beside the no device found...

Based on what you're telling me, The miner appears to be detected MacOS. take a look at this procedure to remove the VPS modem driver:

https://bitcointalk.org/index.php?topic=5053833.msg50638400#msg50638400

You mentioned this branch to cgminer, I am just a little confused.
Should I run the Homebrew code you guys talk about on the first page ?
And then your branch ? Or just run your branch code ?
I am asking because I don't understand the code ..  so not sure how to proceed, thank you!

please read the above link again - it has the exact command you need to compile the r606 branch of the mining software.

well, it's actually a hackintosh I put together, the identifier was installed as a iMac late 2012 running 10.12.6, I wanna say 13,1 but could also be 13,2 (21 vs 27 inch imac)...

When you mentioned swapping from USB2 and USB3 i figured; imo if you have the technical expertise to setup a Hackintosh, I would recommend you dual boot into Ubuntu on a separate drive.  it will be far less PITA to troubleshoot on your exact, same hardware. Even the Identifier (e.g. imac13,1 imac13,2 imac14,2) you picked in Clover can make a huge difference as to how ports are addressed, and is typically hardware-specific to your motherboard and chipsets. I can help out with mining on MacOS, but troubleshooting hackintoshes is out of my wheelhouse.

vh created an r606 branch to the cgminer compile.  perhaps try testing this branch. See this post for compiling instructions:

https://bitcointalk.org/index.php?topic=5053833.msg51597960#msg51597960

1. which mac are you on?  >About This Mac>System Report>Model Identifier  (e.g. MacPro5,1)

2. Do you get some sort of error message?

3. When the r606 is plugged into the mac, in the System Information app, does it show up as a device under Hardware>USB>USB Device Tree ?

I just started getting "found 0 chip(s)" error in CGMiner 4.11.1 and the r606 turning into a zombie; it has been mining steadily since august.  i tried to restart cgminer, changed the power connector and the usb cable, but the same error persists.  I am using Ubuntu 18.04.3LTS.

update - i am running two r606, but just one is borked. The other one is running well at 800mhz since it was turned on.

i downclocked my settings to 700mhz/860mV, and after a few days of "resting" and a few false starts ("0 chip"/zombie errors), the miner started hashing again.

Not sure what happened but i will try to play with my clock speeds some more later.  it is running again so w00t

Re: ColdCard hardware wallet

I just got mine today - I am really enjoying using ColdCard + Electrum, and displaying my addresses on the display. Managing multiple wallets is easy, and i can unplug and keep unencrypted wallets watch-only to see the confirms roll in.    

I still like the Trezor, but ColdCard is a straightforward BTC/LTC only-wallet that can be used tethered, or setup as airgapped.   I tried it on wasabi, but i prefer how i can keep multiple wallets open in electrum. 

the ColdCard looked cheap in the photos but holding in my hand it's worth the price.  it's obvious someone put a lot of thought and pride into how these turned out. Great buttons on the v2. The serial number on the sealed bag matched the bag number located in the firmware for security during shipment too.  

imo if someone is btc-only and likes tactile buttons over touchscreens, i'd go with a ColdCard.

I am using Edge wallet, which provides password + TouchID security for currency i want to carry around.  this is not how i'd carry the bulk of my savings, but for me it is an optimal security/convenience compromise for everyday amounts.

I rely on TouchID becuase the biometric data is stored on the secure enclave chip on the iphone.  This is also secure enough for most of my everyday activities.  However, i never got a FaceID phone and i'm in no rush to upgrade, so i understand the aversion to this technology at least.

Export skeleton wallets for Wasabi Wallet https://wasabiwallet.io/ to support air-gapped use.

i was looking for a new desktop wallet and found out about this integration with coldcard.  i'm also impressed with the thoughtful design of the hardware down to the tamper-evident, clear case.   I have ordered a hardware v.2 to try out.

Re: Why link Dropbox to Trezor for naming accounts?
by
kalus
on 03/08/2019, 17:43:02 UTC
I do fear that linking Dropbox to Trezor is a sure shot way of leaking enough meta data that you hold crypto.
also the dropbox labels are literally stored in a folder /Apps/Trezor/, which would make it plain the account user owns a trezor hardware wallet.

I have held off labeling anything for now, but was considering a second dropbox account on an unlinked email address to make it less apparent.  otoh it probably beats forgetting why i setup "account #1", "account #2", "account #3" etc. a few years down the line.

i think <500w asic miner market is underserved, and will be critical for increasing distribution of hash power.  i will be eagerly awaiting what you are releasing next.

Handy that the PSU is enough for both.
The great thing bout these miners is you don't need a lot of juice to run them.  I would not have thought to start mining again except the power requirement/heat output is manageable for me where i am living right now.

I got lucky at my electronics recycler; there were 6 identical units i picked mine up, with power supplies, sans drives. There is also a non-profit in my city that provides a core2duo desktop + monitor for free after 24 hours of volunteering time.  As a broke person, my free time is worthless enough to take the time to recycle/reuse/resell what i can find.

What controller are you using, RPi, PC, Linux machine, etc?

i wanted to keep costs down so i used whatever spare hardware i had on hand. i am using some dusty, intel haswell processor on an ancient atx motherboard, 8gb ram,and used an atx power supply to power both the computer and miners. Ubuntu 18.04.2 LTS is fine.

I was also able to mine on a macbook, but had to use ubuntu, and a separate power supply for the R606.  i decided to stick with the desktop hardware because i could also run a node off an extra hard drive.

I've been running two R606 for a couple weeks.  They are both stable ~1.07Th/sec, ~800Mhz, 460mV.  these miners are a good size and shape for summer temps.

A few years back i thought i had given up mining for good, but you roped me back in with blinkenlights.

I haven't gotten around to adjusting the parts needed for the R606 to run on macOS yet.

If you want it to try to run it there, you'll need to make an adjustment to use the R606 branch:

Code:
curl -o cgminer.rb "https://raw.githubusercontent.com/vthoang/homebrew-cgminer/master/cgminer.rb"

edit the cgminer.rb file and change branch from 'master' to 'r606'

followed with:

Code:
brew install --build-from-source ./cgminer.rb

I'll get around to testing that when the branch gets merged back.   At which point it should mostly fix itself.

Thanks for this - i was able to compile from r606 branch, but i get repeated "failed to initialize (incorrect device?), resetting" from cgminer.  

when i go to (U)SB management, (L)ist all USB devices, i am able to see two r606 plugged into different ports.  they are assigned "Device 3" and "Device 4".  i cannot get them to initalize, and cgminer hangs in the (U)sb management screen and i must force quit.

does anybody have any ideas for osx? I am running off a macbook5,1 on 10.14.2. thanks.

e- solution was to flatten and install ubuntu.  problems solved XD

Finally, that quiet efficient stackable adjustable 60-120W miner we've been looking for since 2014!

looks great: placed an order for an R606.
