1  Economy / Computer hardware / [WTB] cm1 standoffs on: June 12, 2013, 03:46:32 PM

Anyone got any spare ??
2  Bitcoin / Hardware / [HELP] CM1 R-Pi baud rate on: June 10, 2013, 01:03:12 PM
Ok running a cairnsmore 1 from rpi (v2)
Have raspbian weezy installed, and ftdi drivers (libftdi1)

all is fine and dandy, but...
In the cgminer (3.1.1)/bfgminer (git cloned) driver-icarus.c, I have to set
#define ICARUS_IO_SPEED 57600
Or they will not talk to the CM1...

And before you ask, yes sw6-1 is off

Controller is flashed to 1.5
Fpga's are flashed to std 200 bitstream..

using 
modprobe ftdi-sio product=0x8350 vendor=0x0403

to get the /dev/ttyUSB's


Anyone know how to get these back to normal 115200 Huh

5  Bitcoin / Hardware / [ANN] - EvilMiners - Klondike k16 PCB Assembly - UK & Europe - paypal on: May 13, 2013, 07:17:25 AM
FOR US ASSEMBLY PLEASE SEE - https://bitcointalk.org/index.php?topic=203388.0


You pay only the deposit now, the rest when boards are complete
Please read the sites t&c's
http://www.evilminers.net


Any queries, concerns etc, please post, I will answer quickly

Proposed things to come on the site :-
Expanding to include k1 and k64 (after batch 1)
Expanding to include ArdulonMiner Shield (sample chip being sent to developer)
Expanding to include complete boards (inc chips) (when I can get a local supply)
Expanding to allow payments via chips (board price drops with chip donation) (after batch 1)


UPDATE - 17 June
Well logo failed to arrive....but im opening the site up
http://www.evilminers.net

UPDATE - 13 June
Ok Im setting up a website for the ordering process...
I need 100 boards min for first run.

Im going to be doing this with paypal, and im not taking full payment UNTIL boards are built.
Im going to say the boards will cost 60£, so ill be asking for 6£/board as a deposit.
This deposit will be non refundable, and will go to tooling and buying in the heatsinks

This is not the final price...but its close I feel...
So stand by for next update, announcing site Cheesy

UPDATE - 11 June
Got another quote, again ex vat, ex heatsink, ex p&p

NON-RECURRING :
PCB Tooling                              180
SMT Screen                              220
Pick & Place Program                 188.64

Recurring
Setup and de-kit per run          238.35


10   x  Klondike 16 ASIC Miner Pcb           66.12 ea
100 x  Klondike 16 ASIC Miner Pcb           37.36 ea
200 x  Klondike 16 ASIC Miner Pcb           34.69 ea

 

UPDATE - 5 June
I have a decent quote at last..
Tooling 520gbp

boards - 1  - 168.50 ea
             10 - 59.49 ea
             100 - 43.20 ea

These are in gbp, not inc vat...and of course is subject to change, this does include all parts, but not the heatsink or the asic chips (obviously)

As the price of the boards is lower on the first 100, I suggest the tooling costs etc will be balanced into the costs, meaning the boards will be priced at the following :-
71.39 gbp (inc vat) + heatsink price + postage price
this equals 109.63 usd or 83.74 euro

The boards do need a firmware flashing, but I will sort this as part of my profits, and as stated a % of these profits will goto bkk for the design.

I have requests for quotes out for the heatsinks too Wink


UPDATE - 4 June
Arrow technical is out, too expnsive....

850 gbp tooling, then around 200gbp a board

UPDATE - 3 June
Icon wont do a run of anything less than a batch of 50 boards....
Im getting a quote from them for these runs, but after initial run, I doubt I can use them long term.

Ive rang another today, called Anode, and have another 3 requests outstanding....
There is one left out atm, so still got wiggle room, within my area Cheesy

Ive also contacted 2 more, slightly further afield but close to were I work rather than were I live Cheesy


UPDATE - 31 May
Well good news bad news.....
GSPK and a few others have declined production, due to not having a pick n place machine able to do 0402 components, meaning over 200 parts would have to be hand placed...
GSPK hope they will have the ability in a few months, but cant quote on the board or the lead time for the machine.....
but
They have passed on the info to another local company, that I didnt know about, called icon, who do have an 0402 capable pick n place...
Ill also be ringing up a few other places around me today, Im just going a little further out for delivery, but this wont affect you guys Cheesy
Im still working on this, and still have good hopes that everything will come off ok...

now onto the good news...
bkk has said in his klondike thread (for those not following it) that a k16 will be able to be under populated, as long as chips are in even numbers...
This means a k16 can be used for anything from 2 chips up, so you guys can get your spare chips mounted and hashing...
I feel there is an opportunity here to add chips at a later date, ie send board and chips back in, reflow the chips in place, send back....allowing for greater flexibility in expansion later.

Ill post more when I have more info

UPDATE - 24 May
Chasing down quotes...sadly due to personal circumstances progress got delayed
The quote at gspk has been handed off to gspk design, this also means I maybe be able to get solder mask from them, if I decide to bring this in house at a later date.

UPDATE - 15 May
Been onto another company (quick-teck) for pcb and assembly price...

This breaks down roughly to -
46.45£ (assembly) + 20£ pcb and parts meaning around 65£ each

or 76.48Euro
or 98.96usd

Bear in mind this is purely ball park figures atm
6  Other / Off-topic / [RANT] OKPay on: May 01, 2013, 04:07:50 PM
their verification process is a joke...think mtgox verification was faster......

7 days and counting......

considering these guys must play with a lot of money in the system, and they have pretty high fee's, you'd think they'd be faster at this....makes you wonder what the fee is being used for ......


so....who got verified and how long I wonder Huh?

8  Economy / Economics / mt.gox to btc-e on: April 23, 2013, 11:22:22 AM
Tell if im wrong, but is the only way to transfer USD from mt.gox to btc-e, effectively, is to use okpay ?

Bit instant, is a no go now as they dont list btc-e in the pay too....

9  Economy / Speculation / will asic's kill bitcoin ? on: April 17, 2013, 08:03:28 AM
ok this has been bugging me, so someone please correct me if im wrong, and this is a bit of a brain dump...but

gpu mining is grunt brute force dirty mining...people tweak, rebuild there is some skill in it
fpga is elegant, geeky, clean...people recode, add, expand, adjust the host machine....again skill
ASIC .. is sneaky, fast, clean....but boring and easy

You buy an asic, you plug it in, you get X gh/s you add more, you get more gh/s, in effect an asic on its own is the same as a mining pool atm

So, bear in mind there is a limit of 21m bitcoins (11mil in use now, so halfway) and we've been mining for 4 years now...mostly (with pools etc) in the low th/s

asics will drive the rate of processing up into the upper th/s if not into the peta h/s, so difficulty will increase to silly amounts, but people will expand the asic clusters to compensate

Will we not run out of bitcoins to mine within 4 years or so... ?
Were is the skill, the personal time/work in the mining....is this not survival of the richest ?

I know i know, the rich get richer...but in this environment (crypto, internet, computers) , id like to see the geekiest get richer and asics seem to be de-skilling
were is the fun in mining...after asics....

</rant>

and if anyone wants to offload an fpga or 2 now, shout....im more interested in the geekdom of mining as a hobby
