Ok, found a few minutes to look closer... I think I found the problem. I am really glad I put some scrap 10ga steel underneath these miners. This was the board facing down and it was running only 220MHz. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FJtdom32l.jpg&t=665&c=YMp0YconAQbSgw) ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2F60F7BuDl.jpg&t=665&c=3EWf6scTL7mq8g) impressive> I am going to use 2 fans and these http://www.amazon.com/gp/product/B00008DHPC/ref=oh_aui_detailpage_o09_s01?ie=UTF8&psc=1 back in the day a 40 gridseed orb rack ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fimagizer.imageshack.us%2Fv2%2F1280x1024q90%2F836%2Fp7a8.jpg&t=665&c=ppyWz_G3RDermA)

That should work well, just put it over the top and grill your burgers while mining bitcoin. Warning: may leave a funny aftertaste.

2 units side by side with a few inches inbetween, they were just sitting on the steel like they would on a table. I also had the air outlet side raised about 3-4".

I will forward to ASICMINER for comment. My guess would be a short maybe around that capacitor that looks to have blown up. It looks like the one below that is completely missing. Was there any damage during shipment or loose caps in the shipping box?

No, it's just the way pool hasrate was being calculated. I put a fix out on github last night. cd to /var/www/minera and run the following commands to update: git fetch --all git reset --hard origin/master edit: /var/www/minera not /var/www

Just over 20 straight hours on my RPi with a 3 board prisma. No hiccups. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2Fjt3mYPSl.png&t=665&c=oVFiSyOFuwwxlg)

I think I will wait for your full image tonight I keep messing up the manual compile somehow. This looks great by the way I cannot wait to try it. You rock dude.

Anxious to try your image CrazyGuy I'm hoping it will sort out these seemingly random power down issues on problem boards. I think one of my hashing boards would end up like the burnt one above with several transistors breaking 100C even without load. I think that's where it started with one of the transistors completely burnt off and damage downhill. The heat damage stops with the other side/half of the hashing board.
Has anyone tried to use these usb adapters to connect to PC and just use cgminer? Safe to assume to dip switch them 1-4 and 2x per raspi?

I really like that minera interface. I have been up and running for a day and a half using the BE controller and bfgminer 4.10 as a proxy to run the pool of my choice without any problems besides user error setting it up after moving it. Thanks CrazyGuy for fixing my user error. I have two fans per unit on a fan controller and also a box fan pushing air up from under them after I looked at those pictures of that burnt board. I would love to try minera and turn off the setup I have going with bfgminer as a proxy, although working well, very well to be honest, id like to use this RPI and give my main pc a break. Have the USB to uart adapters shipped out yet?
