Klondike - 16 chip ASIC Open Source Board - Preliminary

[Unacceptable]

Thanks to Steamboat & Kano & others who helped save the Klondike  



Works like a champ!!!!!!!!!!!

Congratulations to all involved.
Glad to see the Klondike is finally working as it was supposed to

It's really wonderful to see the great work all you guys done.
Have been following this thread from the beginning.
This is the best result of this project.

I don't have Avalon chips any more, but still have many K16 parts including the PCB, components, heatsinks, fans, frames with 8 K16 slots, etc.
If somebody are interested, please PM me.

I have some Avalon chips. PM if you're interested.

cool..now only if BKKcoins would deliver the boards i ordered 

[TomKeddie]

Am interested in some parts to DIY a few of these (I know it is a lot of work, my labour is cheap).  Can anyone in Nth America sell me some parts, am looking for 4 x (PCB and semiconductors - I can't imagine anyone but mouser/digikey is going to sit down and split up all the passives).

I have assembly purchased from Steamboat but I with my chips refunded I don't think I'll see any parts for some time.

I want to make a 8 chips per board variant, then play with the voltage a little as per hex16.

Yep, great news !

Way to go !

Who do I send beer BTC to?

Now I need to figure out how to get this firmware onto my Mitten Mining K16s.

The ones I that I have running (replaced C274) are only limping along around 2.5ghps now.

What he said.

Personally, I'd given the K16 up for dead based on the technical challenges and the loss of the primary developer, combined with the Yifu chip fiasco. Major kudos to all involved in finishing this project!

I'd also like to point out Steamboat's remarkable integrity and perseverance. He could have cut and run a long time ago, but he stuck it out and is holding up his end of the deal. Great job Steve!

   Wow,somebody see's my point of view for a change  

It could've been a Terrahash,but instead it's a Steamboat,chuggin along  

Kudo's Steamboat & thanks for hangin in there man!!!!!!!!!!!!!!!

Congrats, It so good that the end of the battle is almost won.

I would love to still build one of these, I have a pcb.
Would be great if someone with leftover components would sell some kits although not economical am sure.

I suspect the pic shortage is over. You should be able to upload the the bom to mouser and work through the parts selection to build yourself a kit...

I just received 50 avalon1s pretty cheap and pcbs are on their way. After I successfully assemble them, I would like to try out some overclocking, with extreme cooling (read: dry ice). Someone mentioned OC above, and was shot down. The K16 uses a standard PC PSU, so as long as one is used that can dish out the increased wattage, we should be alright with replacing the clock and lowering voltage resistors to the chips, right?

The clock is in the chip.  I'm not sure what a voltage resistor is or what lowering it would do.  Don't asphyxiate yourself.

The problem is Voltage regulator from 12V to 1.2 V
2 x 16 A, so @ 1.2 V it is 38.4 W , so 2.4 W per chip max.
@ 282 Avalons are about 2 W
@ 450 Mhz our board is about 92 W so 5.75 W per chip i believe it's almost  the same with bitburner

That is the limitation of K16

But if you have extra PCBs you can throw less chips in there (or beef up the regulator, I'm not sure what size the traces are you can check on the board)

I agree this is the best solution

Who's still in the game of producing the boards for these?
