Congratulations Dxtwo

see PM.

2.1 BTC for all 10

Hi Bogart,

Yup, i meant the PCB as well (not the heatsink)
That back plane would be no good in the water cooling rig i have in mind, i will be just using ribbon cable for data and some heavier guage for the Power.

I have enough components for 10 boards, All parts were ordered from Digikey and comes to about $300 (for 10 boards worth).

I guess i could order some more parts but again, i want to get these working.

If i get these working, I will think about selling a kit which would be (i'm thinking aloud here

one module board
set of components for module boards

then optionally:
components soldered to the module board (except the ASIC chip)
Heatsink or water block
Raspberry Pi instead of controller board with a prebuilt image (and of course the ability to build your own so you can feel confident that your bitcoins aren't going to me

That's all at least two months away for me though, unless someone in sydney has an avalon miner and some spare chips they want to lend me so i can test mine works
Seems to me that the big thing lacking out there at the moment (based on the PM's i'm getting) is the part list that converts the Avalon BOM into the order list for Digikey.
I had to have a lot of help in making that list and until i've got some working boards (September) i'm not confident in giving that away.

So I pm'ed about these. I'd take all 10 for 2btc.

Thanks,
Andrew

Thanks for your reply.

I don't mean the heatsink, but rather the backplane PCB that 8 of the 10-chip boards plug into electrically, which itself then connects to the control unit via a ribbon cable, like is shown here:

Do you have the components on hand to populate the boards (minus the Avalon chips)?  I'd be interested in buying the PCBs along with their SMT components, to try assembling them myself.

Hi Bogart,

I don't have the back plane, i hate the fan noise so i'm mounting mine in a water cooling rig.

I can [produce more module board] but i think it would probably be a better idea for me to create populated boards and sell them.
A lot of people have bought ASIC chips but don't have the hardware to run them.
If i can pre populate the boards, people could solder the last asic chips on themselves, it all depends on whether you can dead bug it i think.

I will have to have a play with my boards and seek advice from those who do this as their day job  


Great signature BTW, i didn't realise it ever got that bad. Do you think the modern day equivalent would be the US simply instructing it's ISP's to block the bitcoin ports?

Any possibility of producing more?

Do you have the backplane board that 8 of these boards will plug into?

If looking for a fully populated Module (8x10chip boards), it looks like Hashtech is accepting escrow with JohnK.  I don't know if that includes the heatsink backplate... didn't really look since I am not in the market.

500$ for 1 board to much .

No i was hoping to get around that by using the protocol directly from a raspberry pi, haven't looked into it yet. My Chips are due September so i've got a little while.
If it looks easier (and not too expensive) to make the controller rather than messing about with odd libraries I'll go ahead and etch the controller

And by etch i mean, "have the 4 layer pcb's professionally produced, cnc'd and silk screened" at hackvarna or i may use seeed who i'm use to dealing with.

Have you built the etch for the controller board ?

1.5 BTC for all 10

Hi All,
Yes 5 BTC is way too much even for ten.
I shall assume you thought they were populated.

I'd like about 0.5 for each board as i'm saving you time and the boards are high quality.
But i will be ok with anything more than 0.1 a board.

I hope someone bids over TheSwede75 otherwise they got the deal of the century :0)


Is there any interest for a board populated with everything except the ASIC chips?
I have no idea how i would test that the board was working. And i'm not sure if you can dead-bug the ASIC chips (though a blower would probably work).

Ah, I thought this was for one of the completed boards!

Wait, what that a 5 BTC bid for ONE of the boards? 5 BTC is a lot even for all 10 boards, but go for it.

Why would you pay that much? You do know that these are just the board only and do not include the chips right? There are no parts on it at all and you have to buy and solder all the parts separatly. Without the right tools, it is very hard.

5 BTC @ 1 (correction: for populated board).

I am interested in an unpopulated board tho.

how much cost ?

Yes, this is indeed the way to do it. Just as posting "order proof" should NOT be a screenshot, but a digital picture of your actual computer screen (with phone/camera) with a post it, or other paper note with username.

Since apparently there is no opening bid amount I guess I'll start off with the obligatory low ball offer of 0.1 BTC per board, interested in all 10 boards. Total bid BTC1 for all 10 boards
