Hi, I am really new on this and i have been doing some research on this lately and have decided that I want to build my own miner. I was thinking to get the board and get the chips and put the chips on there, but I don't know where to get the board from. I have seen a few projects out there like bkkcoin Klondike someone told me those can only take avalon 1 for now. So can someone point me in the right direction for buying a avalon 3 board.

P.S. I saw a video on someone putting the chips on a board, and I was just wondering, what is the jell-looking stuff that you put on the board where the chip is suppose to go.

Thanks,
Retal

You know that you will not get back 90%+ of your cost likely I assume?

the cost to produce your own device (lets say you used asicminer chips to build something like the tube miner) is probably 5-10x more expensive for a small (<20) batch then buying direct, and will require soldering skills and equipment you likely dont have already

Not sure why you specifically asked about Avalon, but there's a mostly open source one that's using Avalon Gen 2 chips:

( link to PCB/schematic/etc. at bottom )

There's also still the Nanofury designs, which takes Bitfury Gen 1 Rev1 OR Rev2 chip:

( There's 2-chip and 6-chip variants for which no schematic/PCB is available as of yet, but if you can find some pictures, it's easy enough to figure it out. )

And for the BE200 chip, there's the AsicMiner Tube designs:

Note that all of these are already outdated in terms of chips.  AsicMiner is working on their BE300, Avalon's on Gen 4, and Bitfury is working furiously (hah!) to get their next chip design finalized.

For anything else, you're mostly on your own, getting datasheets (NDA usually applies), messing with the hardware, trying to get it to work, all that.

As far as 'jell-looking stuff', if it was looking like a mostly clear fluid then that was probably flux.  If it was more silvery and paste-like, it was solder paste.  If it was something else, link to the video.

I agree with klondike that if you're not familiar with board assembly processes, you probably shouldn't be looking into this just yet.

As others mentioned you are better off buying the miners built.  Building your own miner has been dead since GPU days. 

Black "gel" then it's tin lead solder paste
Clear "gel" then it's flux

But as the other said, the cost will very high than buying ready to mine one.
And soldering the asics is not easy job. You need a lot of practice to do it right.

LOL, didn't realize that you already answer that, sorry  :P
Guess i need a cup of coffee  :D
