BFL board project COINTAMINATION - EU facility - ORDERS OPENED for Chili

That means ... Realistically we won't see our boards until the beginning of next year. 

Probably yes... Unless you are ready to have it made as it is... If data I have are correct and no part is defective (and we can't detect defect) I'm 99% sure it is put together right and it is just firmware reacting a bit different do to small differences since you never get 100% same board with different manufacturers(I'm told by ChipGeak that this is not the case but it is hardware error in 1V power supply but still it fits best). I will have my made(if I can't figure it out by the end of the week) as they are and will run them from more computer so it will be easier to make them run. Since they crash only at some specific speeds once you have them run it is go time...

What I plan to test(but this is really the last idea I have) is replace all 1V power components with one bought at later date. I also asked MrTeal to give me the list of them and to look at PnP data if there is a error for one of them. I also asked if there is a way I can get slightly changed firmware to test my theory of voltage/hashing speed problem...

We did look at MrTeal made board and compared it to ours. We did recheck parts used. We did look at all boards with IR and scope. Test components. Look for any spikes in voltage. Look for cold and bad connections. Looked how MrTeal board act and how my... The only think I can't do but this is also the case for MrTeal made board is communicate with 1V power controller. It crashing the board after some time if I do that. So not sure why... All this was not made on every single board since that is a lot of work but since all have same problem...

If anyone has any idea I didn't think of please let me know...

And interesting enough. Now that I used MrTeal made board for some time the board did crash the same way as my do.

Could it be the chips or the way they are being mounted that is the problem?

X-ray checked... Unless the problem is chip itself...

Thank you for your detailed explanation of what is happening or has happened. I actually was not looking for that. All I did was realize today (yesterday) that the original Cointamination board would have taken the same amount of time to get fixed/running. I have written off the investment I made in this project 5 weeks ago (1 weeks after I send my chips to you) and I realized the project (at least for me) will never ROI (in BTC or FIAT). All I want is working boards 39+ GH/s with no special tweaks to get them running in the first place, otherwise the resale value would be ZERO ... which makes is even worse ...  I know the chips are not the problem, something else is. I honestly don't care anymore how long it takes to get the boards working. I equally admire your dedication (to this project) to get everything running!! So, DO NOT GIVE UP!!! You will find the problem and be able to get rid of it! And once I have my boards, I still will have great joy in build my crazy water-cooled miner, because I love to build things.

All the best!

My instinct goes for the power controller, (but maybe I am Influenced by the failure on my chili)

Problems w/ 12V supply to board are out of question?

I did test my boards with 7 different PSU… From cheap 20€ 450W to hi end 350€ 1200W… No differences…

This kind of problems is really frustrating: in older project where worked I lost one week to realize people have changed 2 reel position on pick and place machine. Small components usually are not marked so can be difficult to spot changes.
Also from my experience problems arinsing many days or weeks after normal work usually are eletrolitic capacitor related ( more if heat are involved ).

The "black shadow" of BFL delays seems to darken the path of this project but please don’t give up so close to end. I agree at this moment ROI probably would never achieved but people are in  this area not only for money. Keep you good work

You are right about small components. I also asked to be investigated... Will asked again when they make my broads as they are.

If anyone would like them too now is the time to say.

what will be the difference between asking for delivery now, ..........and waiting a few more days for problem to be fixed?

I will go now too: for me this problem have big possibilty to be fixed by firmware and have some limited rework capacity if found later problem is HW related

Worst case scenario. We figure out that we have wrong gerber for board(I really don't see this as a real possibility since MrTeal did look at them). I'll need to remove chips and more expensive components off the board and remake it on new board.

But more likely is that it has something to do with just one or more component that you can potentially replace yourself if you are good with soldering iron or you can send it back to me and I will do it for free... Depends on cost of shipping I might need to charge a bit for that...

The boards once you make it hash(some need to be restart a lot of times) works. It is only power on problem...

If you are asking for time difference. I think it is probably the last chance for boards to be made this year...

P.S.: They just recheck the components and they are on correct positions on a trolley for PnP... All I need now is a list of components that are 1V power supply so I can replace them.

Hi Lucko
Please arrange for my boards to be built after you have set up the replacement 1v power supply modification.
(the power supply changes may solve the problem)
I have other devices here ( not chili ) that also need multiple restarts, so I can cope with that.

Have you had any more time to investigate my faulty chili?

Forgot. Best case scenario. Just a firmware tweak... This is done over USB cable.

Best case scenario?!??? You are kidding right? 

All this project has seen so far, is the worst which could happen ... incl. a flat tire on your car. 
Why the hell should everything be easy now? I personally don't believe it.

So please find the problem first, fix it then and finally do my boards.

Thx

For my 10 boards I want to get the best boards hashing to me. So best is send me "my" boards which have no big problems.
I will check the send boards locally for usage. If I cannot live with them and if there is only a hw fix possible depends on I can fix it by myself if I know what I must do or I will send them later back to you for fixing.

The additional transfer costs I will pay.

Send me a pm if you need some details from me and how many boards do you can send.

Cheers...

[asjfdlksfd]

I reread some posts. As I understood the regulation looks like wrong. Maybe the sense lines are wrong or not connected, maybe only not as near to the bfl chips?

However maybe it could be a fix to increase the voltage a little bit and stop the self testing.
It will be fine we can disable each chip also retest the chips. Also it will be fine to add a limit command for the frequency for each chip. Are there commands to do this?

Lucko, I found 2 testpads which looks like for 1V rails. Do you checked the rail for stabilisation and for ripples?

Cheers...

So, why are there so many Chili boards on E-bay now?
