Klondike - 16 chip ASIC Open Source Board - Preliminary

[terrahash]

Thanks.

Going through the code, I noticed the Identity ID is still set to  "0xDEADBEEF". I assume we have to manually change this for each chip, or is there any a way to write an automatic script? Also, I think I read somewhere that you got a range from Microchip. Are you going to allot any ranges to the manufacturers who bought licenses from you?

Hi,
All
@ terrahash- BKK is busy and did not get the chance to test fully populated board from the last revision. But did you have this chance , what are the results ?

terrahash said in other thread they will assemble K64 board for testing next week.

The serial # is different from the USB Product ID I received from Microchip. That is used for identifying the board at the USB level and would be the same on all K16/K1 boards. The 0xdeadbeef serial# should be replaced by an actual serial# during production. I'll be adding a ktest command that will enable setting serial# in some automated fashion for production. The only functional difference it makes is for enumeration of chained boards, which is not operational yet.

K1 boards arrived.
I'm working on firmware now but want to get these boards cut up and shipped asap.

Ooooh, I like the white.

White is the color.  It's an alternative solder mask choice

White is a color, the perception of which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in equal amounts and with high brightness compared to the surroundings. A white visual stimulation will be void of hue and grayness. White is the lightest possible color.

When in doubt, check it out! lol,,, thats good Bicknellski!

Meh...

White is nice... shade color whatever.

In art class they taught us that an item that is "pure white" is reflecting the entire visible light spectrum back at the viewer in equal amounts. We see color when the item absorbs certain spectrum ranges instead of reflecting them. A "shade" of white is therefore an object that reflects back slightly LESS than the entire visible spectrum. The color of light being absorbed determines the color perceived by the viewer.

So, "Nice choice of light spectrum to reflect back off of those PCBs". ROFL

(Sorry, see what happens when I'm kept waiting for ASIC chips?  LOL)

Any news on offering DIY kits (basically containing the full BOM) for small assemblers? It doesn't make real sense to source the components yourself when you plan to assemble one or two boards. To be honest I was expecting this to be out there already, since it should be fairly easy to profit from that...

I am planning to assemble my own K1 board when Bkkcoins sends out the PCB's.. Also planing to build two K16s as well but have not done the BOM ordering for those boards yet.. I will be doing that later tonight or tomorrow.

I have a total of $7.29 with $5 standard US mail.  Now there are a few components on the K1 that I have found out of stock and are on back order.. I was able to find most of the parts on digikey as listed..

1.2V, 600mA LDO Regulator AP7217D-12YG-13 Diodes Inc. 600 - Digikey no lead time

Ceramic Capacitor C1005X7S1A474K TDK 0.47uF 0402 12

Oscillator ASDMB-32.0-LC 32MHz QFN4  - http://www.digikey.com/scripts/DKSearch/dksus.dll?Detail&itemSeq=135505227&uq=635131380175856079


and the rest can be found on mouser with the exception of the following.


Schottky Diode, Low Vf SL02-GS08 1A, 30V DO-219AB - can only find 20V when 30V is specified in BOM

Ferrite Bead Choke ILBB0603ER600V 60 ohm, 25% - Mouser back order Estimated Ship Date 2,716 8/26/2013 Factory Lead Time 15 Weeks

Ceramic Capacitor VJ0603Y682KXXCW1BC 6.8nF - Factory lead time 8 weeks.. none ordered yet.


If anyone knows a place to order the back ordered Capacitor.. I think the Bead Choke will ship and not sure about the 20V to 30V difference on the BOM and Schottky Diode on mouser.

I will be checking the product availability on the 300+ K16 components shortly.

Thx for sharing your part-sourcing endeavors with us, but that was not really what I was aiming at..unless you try to offer DIY kits. Part sourcing has been done by various other individuals in previous month(s) for their own projects which can be found in this thread too.
Preferably I'd like to see 'known-to-work' DIY kits (K1 and K16) containing all the parts for their respective builds. Just looking at the github BOMs, it should be fairly easy to profit from that. Or:

- am I wrongly assuming that there are quite some small scale DIY builders out there?
- are we just sitting and waiting for avalon chip delivery before anything happens?
- are we contemplating ROI with difficulty trending?

I think most of us are just waiting on Avalon.. or perhaps looking at burnin who is working on bitfury boards.. as well as an Australian developer who created a "drillbit" system based on what was a cheap 5Ghash/s chip a week ago.  Since then I believe bitfury has increased their prices and now it will be hard to get the Australian devs price again.

I am pretty sure Bkkcoins is also a small scale DIY developer like all of us.  He usually orders most of his small parts from the USA since he lives in Thailand and finds it cheaper to do so.  He had mentioned creating a kit for the boards since you save money to buy from mouser or digikey in bulk.. but since then he has probably not had the time or is frustrated with the rest of us waiting on ASIC chips.

Yes you are right, Bkk is a small scale DIY dev, but has obviously pulled huge development efforts for this project. Yes, this kit was mentioned, yet I see none available (not with him or with others).

but since then he has probably not had the time or is frustrated with the rest of us waiting on ASIC chips.  

Ah so it is coming down to frustration over Avalons movements (or lack thereof). Well I'll come forward and say I would still buy the kit(s), assuming someday my (perhaps worthless) chips come in and I like to start DIY-ing

That is exactly what I am hoping for... If my Avalon chips never show up at least it was a cool project and I learned a lot about SMT.  It would be nice if he created a DIY kit for the components.. kind of a hassle as some parts seem out of stock.  Anyway best of luck to everybody involved in open source ASIC dev!
