There is a small issue with the Kicad files that I want to bring to your notice. The module references do not show up on the Front Silk Screen gerber files when plotting. This is because in the k16.brd file, all the Capacitors, Resistors and Diodes are marked to be on layer 26, whereas they should be on layer 21 (T0 and T1 lines for each module, value 9 is 26). I replaced all "V 26 N" with "V 21 N" and all "I 26 N" with "I 21 N", and now the references show up on the gerber files. I am not sure how this can be fixed from within PCBNew.
I don't think there is a way to edit that in Kicad, as I looked hard for it, even though you can edit the position/size, which I did to make them less jumbled. How they got onto layer 26 I don't know, but I did look in the brd file and saw they were incorrect. Perhaps this was a result of the Eagle > Kicad conversion but it doesn't entirely make sense as many parts were added after. Unless it set something that later kept using that layer. At one point I went in and changed the ICs manually because I wanted them to show at least but I was worried about mucking it up and didn't search/replace everything. If this doesn't cause any problems then I'll do that. Now it's on github it's easy enough to revert. Yea, I search/replaced all those value and everything worked fine. I believe its safe for you to replace them all. |

Dear BkkCoins,
Can you please elaborate a little about the changes that you made to the circuit, to make it work? I know about the missing power to the PIC, and the little jumper cable that you soldered to power it. What is that small red PCB doing? I also got a sample board made around the time you did. I also got 2 sample chips that I have mounted. But for some reason the board is not hashing.
The red board has 2 NOR gates wired as I described a few posts back up above. I use a trailing edge delay circuit. The first NOR gate has P and N, and it's output goes to A of 2nd NOR gate, then through a 100R resistor to B of 2nd gate. B has the 30pF to GND. So the 2nd NOR is ORing the clock with a delayed clock. The UART is set for rising edge capture, and data is inverted when read out of FIFO (~RCREG). This will be updated in the schematic very soon.
The reason it's on a second board is that I had changed the parts so many times on the main board that the PCB traces lifted off. I tried at first to wire the 2nd NOR gate in dead bug style next to the first, but the legs on that tiny gate are too delicate for me and kept coming off. I think I wasted about 4 or 5 over the time I did all that. Once I dug out that board and soldered it down it was easy to connect wires and hook it to the sides of the pullup resistors on main board. The NOR gate on main board was removed because it's output pad had lifted and leg broke off. Thanks a lot. Do the latest Kicad files in the Git repository reflect these changes? AFAIK, it does not. I still see only one NOR gate. |

We are trying to place an order for additional 20,000 chips and instead of the payment page, we are being redirected to http://store.avalon-asics.com/null. When was the last time anyone successfully placed an order? |

I'm order # 432 btw not #430 but was confirmed first order when I called them.
Btw Mine is paid
I am sorry. I just checked again. You are correct. 432 is the first order. 434 is the first "paid" order. Your's is marked "unpaid", as you paid with Bank Transfer. |

+1 please. We appreciate that you commented, but I believe you addressed the wrong issue(s) in response to your order numbering. - Please address order priority is either paid vs FCFS and unpaid\hold\cancelled - is there 10k or indeed 20k chips with recent cloudhashing.com cancellation - some kind of indication of order numbers vs 1st 10k batch or 20k thx This list is incorrect. For instance, there is no order number 430 in our system. The first order was 434.
Please respond to all of the allegations that are being thrown around. We will be doing FCFS with orders that have been paid by yesterday. The 2-3 days waiting period is only for the orders paid with Bank Transfer. We have 20K chips. We will be ordering more today. Avalon will be making chips in bulk. We believe chips ordered today will be shipped at most a couple weeks after the ones ordered in April, not 2 months. We will send an email day after tomorrow to let you know whether your order falls within first batch or not, and when can you expect it to be shipped. You can then cancel your order or choose to keep it. |

0805X106K6R3CT is not available anywhere. Can 08053D106KAT2A be used in its place?

Ok. Acknowledged. I'll work today on preparing my work for release on github.
I would rather have released a working version as inevitably some people are going to see this and think they can jump on it and start using it, and others are going to be critical of my design choices and I won't be able to say "hey, it works". For the record - this is both untested hardware and non-debugged software but the advantages of allowing others to feedback and fix my mistakes appears to outweigh that of keeping it back longer until a working version is available.
My main fear is that now I'll spend most of my time supporting user problems instead of coding/testing. So - be aware, I may not respond to issues unless fixes are also provided.
Awesome. Thanks. Just put a big bold red warning on the first page of the project indicating that its a work in progress and use at your own risk, etc. |

Are you going to release your PC-PIC protocol? I'd like to use the same protocol in my project to reduce the amount of work needed on the miner side.
It's already up on github in the Technical Reference PDF. I still need to add some data format details. I have just the beginnings of a cgminer driver but my work there stalled after I got more focussed on the hardware. I have some plans in that area but have been unable to get back to them. Again, we can help with the firmware/cgminer driver side of the code, and you can focus on the hardware. |

BkkCoins,
We have received Avalon sample chips. We did get about 10 K16 boards manufactured locally as well. We want to assemble one board to help with development and testing. We have resources here that can help push the project forward.
Can you upload the silk screen for the components (those nice little labels that indicate which component is to be placed where on the board)? And if possible XY data that can be fed to an SMT machine?
Wow. This is news to me. And frankly it terrifies me that so much has been invested in my design when I haven't even been able to verify it. However, I'm not going to stand in the way despite the feeling that control is being wrestled away. I'm ready to release everything I have along with a proper open source license but first I would need two things - 1. A public commitment that any info derived from testing/debugging will be submitted back quickly so that everyone has access in a timely fashion. 2. A disclosure regarding any independent firmware and driver development and whether you plan to use proprietary code to enter the market first. The lack of past communication makes me concerned that your main goal is to gaining competitive advantage, and that my materials will be used towards shutting everyone else committed to assembling units, and who have been communicating with me daily, out of the market. I assure you, we are doing the business on minimum margins, and will actually be providing a great alternative to DIY assemblers. Putting those chips on the boards manually is next to impossible, and getting it done from an SMT facility is very expensive if done in small quantity. Our purpose is to not wrestle the control out of your hands at all. 1. We are publicly committing here that any information we get from the testing/debugging the circuit, we will submit it back here on this forum, and to BkkCoins so that he could update his designs. Any changes we make to the circuit will also be submitted back. 2. We won't be using any proprietary code. We will be licensing the code from you. If we do make any changes, we will release them to public. We are committed to pay a royalty fee for every board we sell to you. We actually have the resources to design our own circuit, but we wanted to help the open source initiative by expanding it further. I have offered my help for the firmware in the past as well, but wasn't replied to. |

I believe BkkCoins has yet to receive any sample ASICs. Maybe you could send him one or two ASAP priority. I’m sure I’m not the only one here who would be willing to help pay for shipping and reimburse you for the parts. I also would like to help with testing, but BkkCoins really should be highest priority. Drew We can certainly send him a few chips. BkkCoins, please let me know your address info in my inbox if you still haven't received nay chips. I would be happy to send you a few for testing. |

then I'll probsbly need the same thing.
Funny my SMT contractor did no mentioned it
I wonder why not, its impossible to assemble a board if you don't know which component goes where. Of course I can look at the datasheets of the controllers and the components to figure it out, but since BkkCoins already has it, doing it myself would be just a waste of time. |

This one only has the markings for the Avalon chips, and fan/i2c/icsp header. Doesn't have any other components. |

Good operator can program this preaty fast- a few hours By silk scren you meen stencil ? Not the stencil, but the silkscreen used the print those little label (C1, C2, R1, R2 etc) on the board, so that the people assembling the board can know which Capacitor goes where and which Resistor goes where etc. |

When will USD prices show up on the website?
Soon. By this weekend. |
|
|
|
|
Just to clear things, we will be accepting BOTH BTC and PayPal.
We have the sample chips. We will most likely have a few sample boards ready by the weekend.
I will post pics of the chips in a little while.
|
|
|
|
|
We have decided to start accepting PayPal, because of the demand from the forum members. We are still deciding whether to keep the pricing in BTC and change USD prices daily according to the bitcoin rates, or to change the prices of all the products to USD.
