Hi,
Do you have the chips in hand (zefir states he has posted them) and how much for shipping to Australia?

Hi strombom,
I would like to purchase a controller board from you.
Is this possible? I'm not in a huge hurry, my chips don't arrive until September.

I am trying to make a water cooled Avalon.

Thanks

would you need a bot?
couldn't you simply place a buy or sell order at you chosen level.
ie it's trading at BTC70, you put a sell order in at US$90
If it goes that high, your order if fulfilled, if not, at the end of the trading day, your order is cancelled.

I might be wrong, i'm not a bitcoin trader but i do trade on the ASX.

Avalon controller options?

Hi,
I'm building an Avalon Clone and having dived head first without doing enough research i'm now stuck at the controller point.
The avalon github doesn't have the BOM or FPGA stuff needed to make the controller.
I don't have enough skills to program my own fpga.

Does anyone know of alternative methods of controlling the Avalon modules?

(yes, i know i should have built a klondike instead, bit late now I've got all the modules :0)
Plus i found a neat way of water cooling and stacking it all together in a nice quiet (sort of) box.
The klondike pcb size (10x10) doesn't lend itself to cheap off the shelf water cooling

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 Smiley

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 Smiley

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 Grin
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.

Any possibility of producing more?

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

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  Smiley


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?

Mods: i'm unsure if i'm allowed to cross post, please delete this if i've broken the rules

I have some spare avalon PCB modules that i'm selling
I have 20 boards but only enough components (ASIC) for 10 so i'm selling the spare ones now to help reduce my outlay.

The boards were commercially produced (no backyard etching) and are 100% electronically tested.

Have you built the etch for the controller board ?
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.

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).

[SOLD] Avalon Module boards for sale
by
magnets99
on 19/06/2013, 12:03:24 UTC
Hello there,

I have 10 unpopulated Avalon module boards for sale.
http://i.imgur.com/TTJoR1r.jpg

my background is in electrical engineering and I am replicating the Avalon design.

I've had more PCB's made than I need and I intend to sell them to offset my capital outlay.

As you can see in the image, i'm going to start populating mine, but i only have enough parts (and ASIC AVALON chips) for 10 boards so i have a further 10 available.
I can get more made if the interest is very high.

I am based in Sydney, Australia.
You may inspect before paying if you wish. I am happy to post internationally however I will ONLY post with tracking.
Australian orders will be sent by Express Post with Tracking (next business day)
International Orders will be sent by Express Courier International http://auspost.com.au/parcels-mail/express-courier-international.html
Please note I will only post to countries that will provide tracking and signature

If you want one, reply to this thread with your offer and how many boards you want.
I don't know how much interest is here, so i guess i'll leave this thread open over the weekend and post them out on monday.


The fine print:

I will pick the highest offer until all 10 boards are gone.
Please note Postage is on top of your offer (It will be about $10)!
I'm happy to write commercial sample on the package as that's what it is.
You are responsible for any customs charges (if applicable)
I would appreciate a + of trust if you are happy when it arrives (though this isn't mandatory).
I will contact you via PM to get your Postal address and give you my BC address.
Feel free to make an offer by PM if you have to but i would like to make this transparent for all. I would not like to be accused of making up shill bidders etc.

Any questions please do ask (though i'm off to bed now, so it there will be a delay for a reply, it's 10pm here and i'm a tired father!)

FAQ
Whats with the writing and the silver bowl?
My username is in the picture to show that they are my boards, I put the bowl in there as the warped reflection will make it hard for ass-hats to photoshop their own username into my image.

Are you going to sell populated boards?
I'm not planning on it at the moment, i have the components for 10 boards but i haven't made them yet, i would not like to sell any until I've proved i can make at least one.

Do you have any more ASIC chips?
no

Do you want any more ASIC chips?
no

Where did you get the boards made?
Hackvarna

How do i know the boards are good?
They are the avalon design, i've made no modifications at all, if they don't work, then mine won't work either, and neither will anyone else's.
Hackvarna do electrical testing on each board so there should be no broken tracks.

How are you going to solder those? they are tiny!
Yes, yes they are. I will be using an IR reflow oven, a steady hand and probably quite a lot of swearing.

How much to post to the USA/UK/Canada/myhouse?
About $10, i'll get you an exact price when I know where you are and how many boards you want. Don't worry about this too much, i will not charge you anything other than what it costs me and i will put (a copy) of the receipt in. I think there are two options 2-4 days and 2-7 days, the latter being cheaper. It will be your choice

Re: Is buying btc on ebay legit?
by
magnets99
on 14/06/2013, 10:19:20 UTC
I used localbitcoins.com
which was a link i got from the Newbie FAQ on this forum :0)

it was very painless.
I setup an account.
Picked someone with a good rep and the same bank as me
tranferrred them money, waited about an hour.
got bitcoins in my localbitcoins wallet
then i sent them from there to my computer wallet.

one thing i have noticed which doesn't jump out at you is transferring bitcoins is not instant.
mine took about 3 hours to confirm.
You can pay a fee (it's under settings, main, Pay transaction Fee) and then it goes much faster but if i wanted to pay banking fees i'd just use a bank.

who gets those transaction fees anyway?

I must admit i nearly bought through ebay.
I looked at mount gox.
then i looked at everything i had to do, and the wait and understand how to use new software and then read about the how careful i have to be.
And i know ebay, i'm comfortable with ebay and i've used it for years.

if it had been closer to the exchange rate i would have bought it (not from this guy though).

but then i would have found i'd need the software anyway... and so on.

you only have a feedback of 20 on ebay and it's 100%
why would you say you've had chargebacks far to often?
