[REFUND PROCESSING COMPLETED] K1 Nanos - Big Picture Mining Cooperative

[Bicknellski]

I'll take 16 K1s complete with all chips except ASICs as soon as you can provide them.

What is the price?

Ok my bad everyone. To be clear this is a straight buy K1 Nano with chips.

If you want just K1 boards WITHOUT AVALON CHIPS go here to this link https://bitcointalk.org/index.php?topic=252113.0

Ok thanks,

I'd like 16 WITH the ASICs but you probably are on a much longer time schedule for those.

Ok thanks,

I'd like 16 WITH the ASICs but you probably are on a much longer time schedule for those.

We may have some in July at the same time as the K1 boards. Depending on:


1. Avalon Chips
2. Customs
3. BKKCoins prototyping schedule
4. Luck
5. More Luck.

[joeventura]

Ok then perhaps I will take 16 of those if you can provide

Tomorrow is Friday and the site is almost ready.

[Bicknellski]

Please note prices will be posted up on the website later tomorrow with a payment gateway.

Code:

Tentative Pricing Matrix K1 NANOs - (Check Site Tomorrow For Final Prices)

1 - 9 Units 0.99 BTC 
10 - 49 Units 0.89 BTC
50+ Units 0.79 BTC

Based on Mt Gox prices at $86 / BTC.

500+ Larger Group Orders ask for pricing and shipping dates.

We are pricing so that more people will trend towards group buys or bulk just so it makes our shipping easier. Comments are welcome.

Note that we will be using USD to set the BTC price for each unit.

$85/K1s for 1 - 9 units
$75/K1s for 10 - 49 units
$65/K1s for 50+ units

Any orders larger than 500+ will need to contact us as we have variable shipping of Avalon chips so we can not guarantee availability for larger orders. We welcome group buys but remember we have production running from July to September for these K1s so may have situations where we are restocking if sales are brisk.

What is the pricing if I provide the ASIC?

[Bicknellski]

Can't do that as I stated before. We do not have the time as the logistics would be a problem. You can either buy the full K1 or check out the group buy for K1 boards and make them yourself. Check the DIY thread here:  https://bitcointalk.org/index.php?topic=227186.0

[merv77]

any idea when K1's will be ready to ship?

If waiting on Avalon chips, when are you expecting them approximately?
And how long after chips arrive will K1's be ready to ship?

Thanks

We should have k1's ready to ship in 3-4 weeks depending on when bkk completes the k1 design and when the chips arrive.

[Bicknellski]

We are currently working on the shipping / payment gateway today. I suspect this will be ready today or tomorrow.

What will you be approxmiately assuming size wise of these Nanos?

USB Drive - Powercable on a small unit or a big rig?

They will be USB sized

50 mm x 25 mm are the square dimensions.

Note: If the K1 is cut from inside two other boards then the board width could be 24mm according to BKKCoins.



CHECK FOR CORRECT LENGTH FOR HEAT SINK (36mm x 25mm x 10mm)

You plug these K1 Nanos into a USB port or hub.



We are currently sourcing hubs, raspberry pi's, sd cards. We will post more information as soon as we have fully tested our burn hubs. Potentially we want to be able to burn in a large number of K1s at a time so we will definitely have a robust hub that can handle a 24 hour burn in.

The heat sinks, which are attached with an adhesive heat sink pad material at the end of fabrication, is 10 mm high on top of the board height. So be aware of that for spacing on hubs. We want to make sure the heat sink is sufficient for our users for potential over clocking beyond 282 Mh/s. Given the test so far BKKCoins has had stability with air cooling and fan at 341 Mh/s per chip. We are confident that he will push the design further.

Updated Parts List for K1Nano.

As we are sourcing parts from outside Indonesia and brought in our prices for parts are higher and our fabrication is in Batam for the boards.

Original parts file on github: https://github.com/bkkcoins/klondike/blob/master/docs/K1%20Parts%20List.ods?raw=true

[Bicknellski]

Yes my error everyone. The entire length is 50 mm. I will have revise my picture. Thanks roybitcoin for pointing out my error. The guys doing the buying of the heat sinks have the right measurements I on the other hand was a tad sloppy there.

Given that a typical USB plug is 14 mm I will assume that the board for the K1 is 39 36 mm. To check this someone can verify on the Github files for the K1.

https://github.com/bkkcoins/klondike/tree/master/kicad

Almost. I just measured a board here. Your 39mm is 36mm. The 25 is ok but when cut from a panel of 2 or 4 would probably be 24mm, depending on cutter blade loss. So that is determined by how you assemble them. Most PnP shops will want to put lots of those in one big panel because they're just too small to do one by one. - BKKCoins

I measured 35.88mm from the gerbers files.

Oh the tension... so.... so... sooooooooooo close guys.

Pentel Asks:

Any update on the Klondike K1 Nano USB Bitcoin Miner's?

BKK Responds:

I expect to complete a final revision of the board in a couple days, and then order a batch for final testing. The K16 has been verified and this is based on that, uses same firmware and cgminer driver, which are working, though quite basic still. Once boards are ordered I'll have time to polish the code and get a bootloader added (which allows upgrading via USB).

For anyone planning to use the board design for their own project / products, note that I will be changing it to the QFN version of the PIC and the parts list will have some changes.

The K16 has been running quite well for me in testing. The HW error rate is still a bit high and I think some board changes planned will help with that.

I haven't seen it happen again after changing the USB cable to the high quality one from my Canon camera that has a ferrite core near the board connector.

I've wired in the inverters now. The signal has very sharp/fast rise times now and it's easy to see the clock delay is 50nS. I tested it manually in ktest and got all GOOD nonces up to 420 MHz doing repeat work filling the queue . At 430 MHz they came back BAD.

Unfortunately on cgminer the error rate hasn't improved. I haven't run that long yet but I'm seeing 3% - 5% error rates. I believe this is now related to noise on the PLL and instability. It can go quite a long time with no errors, and just when I think Ok, it's down to 1% now, but then a bunch pop up and it's back to 3%.

I'm moving onto final board revisions now. Hope to have a new K16 release later today and k1 tomorrow sometime.

Just teasing out the last little problems with the website everyone. We should be ready with it Monday at the latest. Note there is a group buy available to get those lower prices right now with Beastlymac. Tentative shipping prices are posted there as well. As we are doing BTC only our shipping prices will be estimated and before delivery we will confirm based on exchange rate as we have to pay in fiat for shipping.

Indonesian community members there is also a group buy here:
