I plan to try the new firmware at the weekend.

Hello

For everyone and especially for Lucko:

Have someone switched Lucko's made boards firmware to more efficient one as announced by MrTeal on
https://bitcointalksearch.org/topic/m.6102864
What are results? Boards run stable at 1V and lower temperature?

Regards

I think I can do better than this fiasco myself, so I've decided to do a HF chip group buy linking direct with peppermining.com

Click on the team tab if you need reasurrance that this is a serious effort that will deliver.

Excuse me ... so it is my fault that you had boards made which seem to be broken? Did I or anyone here else tell you to skip 'the normal process' with a the safety precautions or did you make the call yourself? My guess is the latter, so fix it and deliver the boards in a workable state.

Thank you!

P.S.: Send a board to the MrTeal, he might have the time to find the problem. Worked sort of with the first broken batch.
P.P.S.: Out of curiosity, have you ever produced a batch with working boards?

Please say send me my boards now. You will see they are made and they don't work. I would love to do that so I have less of them to fix and someone will confirm the problem... It didn't run dry I'm just sick and tired of this. I'm working over the day and fixing this board at night. What else do you like me to do. Last week I end up in ER because I was neglecting to drink enough and my kidney stones return. One4many pushed me in making boards ASAP but had every chance to have them make sooner. Same goes for you. So please put your money where your mouth is(calling this a scam) and say send them now. Unfortunately this batch since we were pushing time limits went bad. I have no clue at the moment what is wrong. I tested components MrTeal told me that can be wrong and they are all OK. I'm fixing the board blind since I don't have full blueprints only assembly instructions. It is no fan testing components 1x0,5 mm.

Well I know a person who bought your boards and they are working just OK so really not sure about that but it was your choice. But Yes I agree it was my mistake giving everyone so many choices to make or wait. I should just make all boards not have made 6 small batches that increased the cost and chance to something go wrong with assembly. So yes that was a mistake on my part. The rest please point out where was poorly managed or was I less then competent.

It's a shame, i saw the cointamination board hashing on eligius, and it was really good.

Quite how we went from that to this is one for the XBT history books.

It's probably the ASIC...

This went bad long ago.  I was lucky to get my moneyback about 2 months ago.
Very poorly managed.  I would not go so far as to say it was a scam.  But in the end, the leader was less than competent.

I call scam, enough is enough now. I guess the stream of excuses has run dry

Another 2 weeks have passed  
... have you been able to find the cause of the problem of the boards sitting on your desk for a while?

Cheers

I'm OK with that...

Now I have boards made but there is again a problem with them. Since we skipped test to get them done ASAP(it would take at lest one week more) it looks like one of the components is incorrect. Still didn't find what that components is...

If someone is interested 24 BFL chips for sale at auction. Minimum price is 5 € per chip:

Happy bidding...

For german user, I will sell Chilly's from Lucko next time at ebay.de.

They have installed a fixed firmware which pre-heat the VRM's slowly so the heat up problem is very seldom now only if my internet connection drops more than a few minutes.
No hairdryer heat up is needed for them. So they run stable after flashing the work around firmware.

Check ebay by using search word Chilly :-)

Lucko, I hope it's ok for you. If not delete this post simply 

Cheers...

surely the chips that havent been mounted are dead by now?

Got the message that they started production today.

PnP has power again but also a long que. Did ask them when thy can fill me in and the answer was not before Friday. But that doesn't mean that this will happen on Friday. It means that it will not happen till then for sure... They will look for first available opening...

Lucko,

any updates on the production board side?

Talking from memory but I think it is about 10$ or something like that... And you need hot air and steady hand to replace it...

Thanks Lucko - no chance to get it back. Too the FT-Prog will not detect it... seems the chip is somehow gone. Do you think this is repairable by soldering a new chip (and what is such piece costing)?

I am a complete noob on the hardware-side.... 

It is getting batter. We didn't have strong rain for a week now... I think we will get "connected to continent" today...

Yes I looked. It sounds like common BFL not just Chili problem. FTDI chip... You might just need to reprogram it. See if you can detect it:
