Rain and snow took out my miners....

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.

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.

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

[lightfoot]

Let's see. This is a picture of the junkyard full of mining gear. About 350gh here.

A wide angle shot of the sheds. Good solar porn here.



And a close-up of the board work. Brand new FTDI chip=Happy unit!



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

Nice man caves.

The angle of your solar panels should be between 35 degrees (summer bias) to 45 degrees (winter bias).

Thank you.

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.

That's beautiful, both rustic and futuristic.

Nice property!

You got sugar maples?

Nice space to work from.

That seems like a lotta work where do find the time?

....awesome images...

I'm impressed with your solar setup for those miners!

[kthejung]

let the old tech die and put some 50 T/H machines in there next mining season.

[freedomno1]

That was pretty cool I like your setup and location
Thanks for taking the time to share

Ha! you proved all the doubter's wrong ,where's your god now them basturd's thank's for the pic's
