Ha! you proved all the doubter's wrong ,where's your god now them basturd's thank's for the pic's
That was pretty cool I like your setup and location
Thanks for taking the time to share

let the old tech die and put some 50 T/H machines in there next mining season.
Let's see. This is a picture of the junkyard full of mining gear. About 350gh here.

I'm impressed with your solar setup for those miners!
Nice property!
You got sugar maples?
Nice space to work from.
That seems like a lotta work where do find the time?

That's beautiful, both rustic and futuristic.
Nice man caves. 
The angle of your solar panels should be between 35 degrees (summer bias) to 45 degrees (winter bias).
Thank you.The angle of your solar panels should be between 35 degrees (summer bias) to 45 degrees (winter bias).
Depends on your latitude. I also tend to run them a bit towards the flat side to maximize winter power on the main shed (they can also run the 24 volt battery bank for emergency power). I tell you, when you lose power it's *really* nice to wake up to a running fridge and a hot cup of coffee. Makes life better.
And if you look carefully you can see where one of them bent due to a foot plus of snow this past winter.
The shed is actually well over 100 years old, the house builders liked it so much they moved it here in the 50's when they built the house. Drilling into the 2x4's is like drilling into iron.

Side note: When you put the chip on make sure that you align the dot on the chip with the dot on the board. Otherwise all hell will break loose and you will be placing yet another order with Mouser. :-)

very nice PV setup, maybe you should consider installing some wind turbines next for a hybrid system.. maybe the vertical axis ones if you wanna save on civil work

Yes, eye candy is always nice.
What is the electricity rate at your home if i may ask?

Working on it. Takes forever for me to bother uploading pictures here.
Anyway, I finally fixed the BFL single miner board. It was a dead FTDI chip, must have shorted in the rain. Replaced the QFN chip with a LQFP and after getting all the pins soldered down perfectly the board is up and hashing at 54gh. Sometimes I think I can fix a rainy day.
I submitted a paper for DEFCON, we'll see if they go with it so I can do a talk about all of this. One thing I will put in: No matter how fucked up things may seem take your time and just never give up.
One step at a time. One step at a time.

Been a day. This morning the Chili was down again with no lights and a sick in BFGMiner. This evening I tried plugging it in, got 4 LEDs on the right side of the set of 8. Not good. Tried cleaning the CPU again, still no dice.
Took the cooling block off it and started to work with the loupe. With the chips exposed I could see that the back set of pins for the CPU were still corroded, so I cleaned those with alcohol. Also saw that the chip on the side of it was also gunked, cleaned that as well. Then fired it up one last time.
Two left LEDs came on and I unplugged it *INSTANTLY*. Reflex, then I felt the wash of heat come from the chips. Man those things run beyond hot.
Put the water block back on, assembled it, she's up and hashing again at 30gh (I have the low power firmware on it now. 120 watts at 30gh is better than 230 watts at 38gh). Moral is that water damage is a *bitch* on boards, and you really should clean them up well.
Next up the single, which checks out otherwise, just need the FTDI to arrive. That should get me back to 900gh; this puttering around at 800 is for the birds (now 830).
Take your time, and things can be fixed.

Ya I am the IRS.
don't post any pics.. everyone asking are IRS agents that will show up to your door to ask you about your taxes and also bring a local property inspector to check your permits for that shed, bill an engineer for code inspection on your behalf and raise your tax rate
LOL, there's so much bullshit in the Bitcoin world nobody believes it until they've seen a photo/video is all.
I'm sorry for your loss bro =/
Well, I got the Chili working, looking at the CPU under a loupe I could see that there was copper sulfate on the CPU chips which meant it was wet and running for a time period before the power supply blew. Must have been one hell of a storm. Cleaned the chips with isopropyl alcohol and it comes up sometimes when fired. Running now on a BFL single/30 supply, will see if it holds.
Also tried replacing the fuse on the PSU and the house breaker tripped. Wow. Took the Corsair power supply apart and I can see damage on the underside of the power board by the HV switching capacitor. Looks like water pooled under the board where the components were, aided by the plastic insulator, and blew things sky high. I'm guessing the FETs shorted, wow.
The Single is operational but needs the FTDI chip replaced. That's the project for tonight. However since I am one PSU short, running it is going to be a trifle complex. Hm.

Pictures so us visual learners have some perspective of your plight.
Nice that you can salvage in this situation. Keep Calm and Carry C3H8O.

Since the shed is on the plat documents (it's actually from the 1880's) and everything is above board that's not a problem. It's also insured but I'm not going to bother with that for a dead miner.
The solar system is doing well: I just checked and it's putting out a total of 6.6kw per day which helps to offset the miners to an extent. Likewise all 10 miners in the shed are running normally, pumping 380gh into the blockchain.
I'll start working on the miner this evening. Might as well take a look.

Your the guy who causes traffic on the HWY to come a hault becuase of an accident on the side of the road. Arnt you?
no HWY
When's the funeral? Picture of it, please.
No, honestly, sorry to hear this. But I also would be interested in your solution regarding solar power...

Sorry to hear about your loss....but,did you do your solar yourself 
I'm VERY interested in your setup,model #'s & wiring info.
I live in Fla & have conflicting info from many sources on compatibility of panels,gridtie inverters & lots of other supposed issues.
I need experience & expertise I guess,which in solar I lack ATM
Thanks for any sharing any insight
Hope you get back to "normal" ASAP bro

Can you post pictures.
Sure, I'll post them tomorrow or something. It's just a tangle of wires and such in a work shed, but the solar panels on the roof are cool (1.5kw on the main shed, 1kw on the second shed, Sunny Boy 1800/700's doing the grid tie) Bag of rice can't save em or are they totally fried?
Not sure. The Corsair has a faint smell of burned inside it, I've got it in front of the fireplace insert for the evening to dry out. Will see tomorrow.The miners were not wet at all, what I think happened is that the 750 either threw 120 volts onto the 12v line briefly or something that caused the units to go to ground through the USB lines. Which makes no sense as the Corsairs are pretty high quality power supplies, and I have everything plugged into GFCIs explicitly to catch a ground fault before it exceeds 10ma. All GFCIs are tested good. Also odd that two jalapenos were plugged into the same supply and are fine. Odd.
Not a BFL issue as the Chili is even more screwed up. I can fix the Single pretty easily, just pull the FTDI chip and replace. However unlike BFL Mr. Teal has not released any schematics or code so I can't easily troubleshoot the Chili.
Ah that sucks well lesson learnt lock the shed and make sure there are no leaks

I would check through everything. If you rent, maybe your it includes a certain amount of renters insuarnce? Thats how it works for me, 10 dollars extra a month, didnt know I even had it for the longest time.
Couldnt something like that be covered by insurance. Worth the investment next go around.
Perhaps, however given the residual value of the miners and my "I'll deal" sentiments I'll eat the damage. I will however consider reloating any future miners under the bench or something :-)

Well, it was bound to happen. I have moved about 300gh of my mining power out to my solar powered shed to take some of the heat load off the house. Today we had massive rain and snow in MD, and in the afternoon I got a note that the shed miners were offline. Figured they tripped the GFCI.
Nope. Shed door had blown open and rain blew in. Got one of my Corsairs wet (had to be the 750), it's dead as a doornail. Not sure why. However when I moved a spare power supply in, two of the units didn't come up: My Chili and one of my 50gh Single boards.
The Chili is dead, barely starts the fans, no lights. The Single comes up but no USB. My guess is the power supply faulted and took out the FTDI chip somehow, which is odd since the PSU is grounded and everything is on GFCI's. Great, the 100gh of hashing and $80 power supply failed to protect the $5.00 GFCI socket.
Everything else is up and running again and I have latched the door. 32 degrees out now, I'm sure it will be in the 80's tomorrow. Gotta love climate change....
