I am want my money back or 2 bridges that are working.

Can someone from Batch2  buyers confirm,  that this  product  is working with his Titan ?

I have not received mine from US , but I always assumed that they all working.
Only one is shipped to me from the US , and this does not work. Behaves exactly as described above.

The rest 9 pc will come  later in the hand luggage.
However, even if they all do not work , they must be with one and the same type of design error, and therefore easy to repair.

So I do not worry today about it working or not working status.

No design error. But if more than just you two report non working bridges i'll just upload a video of me plugging a bunch in and seeing them work.

Still you don't believe us that your bridges are not working ?
Should I make you a video ? I just need 15 min and you can have a video comparing your clone bridge with the original bridge

You could have blown something or broke something yourself. A video after the fact is useless.

Hm.

Ok, some rambling thoughts here from someone who does his best to try and fix these things. Let's start by keeping the following in mind:

1) Titans, and most bitcoin mining equipment made are not the paragons of reliability or consistency. Ok, they're crap. Total and complete crap. We bought crap. This is not consumer grade stuff, and if it was made to be that, we would never have it. Economies being what they are, people want the fastest cheapest shit you can get NOW, and the mining companies cater to this. They have to, if they don't someone else will and they go out of business.

Which is sad since a simple optoisolator circuit on the Titan would totally fix 95% of the major failures. Probably cost a dime. But not done. Oh well.

2) Given (1), this stuff blows up. Yes, it sucks, I understand that. But especially when people run things full-bore, don't keep the equipment clean, and don't keep an eye on things, they blow up. There are few safties built into this stuff, and while the builder would expect people to run them in a 70f data center people run them in fracking barns.

3) Fixing this crap is hard. Designing solutions is hard. You're talking no documentation, no manuals, no support, the people who built it either got out of business, are focused on new models, or enjoy spitting on you for stress relief. So when it does blow up, either someone steps up to try and fix it, or you're fucked.

4) Even given (3), the wide variety of ways one can screw up installs makes fixing this stuff even more fun.

And the biggie:

5) If you want people to try and fix this stuff, try not to flame them too hard. I'm sure you're frustrated, the vendor ignores you, and it might feel nice to take the stress out on someone who is trying to do something. This is complex: Too much flamage and they stop fixing things. Then the community is back to 2 and fucked.

I don't know qberty, or most people. I think it's pretty simple to see why the bridgeboards blow up: KNC did a suck job of not fusing the fucking inputs. And people run these things on mammoth power supplies that will happily source 5 volts at 200 amps into a Raspberry Pi that decided to blow up and expects 1 amp of power from a USB cable. Sure I can fix these, but if the person plugs in the same burned out Rpi with the same tank power supply the result will be the same. Foom. So now what?

Qberty took some time and actually built a new board. Cool, but as we're figuring out the problem isn't just the bridgeboard it's the lack of a fucking fuse to limit current and the fact that the Rpi's are kind of cheap and short out. So if you blow your bridgeboard and you put in a new one, and the Pi is still fucked the result will either be the same or something else on the board will blow open. Or the power supply cable will fail open.

Point is if you flame his ass too much he will send you back your .2btc and just quit. Or tell you tough and just quit. Which is bad, if we want these things to keep running we need more people to fix them. That's why I write all that technical crap in my posts, so other people can FIX them. Because Bitcoin/Litecoin/Shitcoin needs all the help it can get to succeed.

Fixing this stuff isn't simple: I just had someone's unit come in that blew a power supply so hard it cracked FETs. When I pulled the supply things looked ok so I put it on my test controller. Whereby it promptly burned out my test controller, setting me back a week while I got more damn power and FPGA chips to fix it. The thing blew up so hard it took out the supply next to it and shorted +12 right onto the SPI line. Fucking great. It's frustrating but I deal. And I tell people whenever possible to slow the things down because they blow up less at 60mh and lower. Ok, let's not go there :-)

I'd be happy to look at one of these bridgeboards, but I'm not going to flame people publicly if they're actually trying to help Titan miners. It might be a simple error, it honestly might be a bad board, it could be something on the controller or the cable or the Titans that blow the board up. See above for "anything can happen with these things". They're unpredictable, they were made that way. Because it was quick and cheap. Let's keep that in mind and relax the flamage a bit.

Goal is to keep people mining.

This. When I send you some of my unworking cube boards, i'll throw in my own bridges so you can take a look of how they can be improved (though honestly, i've tried a lot of prototyping and no matter what I do to the bridge, the RPi and controller board just messes with shit).

Well looks like Kncminer now is gonna get bought out. (or has been) see below from coindesk

http://www.coindesk.com/knc-miner-acquisition-gogreenlight/


Got to give knc evil cred thou. They NEVER on their main page said anything about bankruptcy in any way shape or form ..even now

http://www.kncminer.com/

They managed (though knc insiders I presume) to keep the majority (approx 215 Titan miners) for themselves with their super secret sale.
(Notice how they contact coindesk with news they want but hide news like the fact 215 scyrpt miners were sold this year ..when no scrypt
miners are being sold or manufactured this year...but hey....can't do that ....have to rig the process)

I got 6 out of 24 first batch (we found out by accident asking a question vie Kurt's old tech email the main page emails on above kncminer.com link does not work..
thus the lawyer told us about it)..this was a closed auction. The next few auctions of the remaining 200 or so miners *used and new* were open auctions..which means you can
see what was bid. This is helpful so 'smucks' like me and my friend don't take your 1st 24 batch 2 5 cube miners away from you (then again 20% damage error rate by temp
workers and wrong thermal paste on the works and shipping/packaging sucked also added to damage....but hey it was knc and evil we expected no less)

Thus we were crushed by whales...specifically imho KNC in the fact are you really going to bid up on the 140 or so miners you now have 100 bucks to get the last 20?
(er well ROI from what I figured at 3-4c kwh in Boden Sweden was 3 months so maybe)

but anyway 'super secret double probation open bid auctions' (after losing 1st batch to me and a buddy) ....the lawyer imho still thinks he sold us btc miners

So getting the only real profitable stuff out the door in the data hall (Titans) they have unloaded now the BTC stuff to this new group of folk which will keep knc folk working there
(not the founders) but still....I sense a future bankruptcy/ train wreck. Feel sorry for the IPO folk who put money into this ..they got soooooo screwed.

Anyway my view for what it is worth on a rather 'interesting' end to KNC which I managed to not only WIN (they are bankrupt) but score some equipment.
(Calling it a win.....despite the knc insiders/founders getting millions and hot Swedish Trophy Wives....I'm in denial .but damn it I'm calling it a win!)

Denial .....sometimes the only way to boost your ego in this deluded ASIC kool aid drinking endeavor.....

Problem is not that I got 6 new miners I want more..argh! (stupid hobby)

But damn..got to admit even now that they are gone they lived up to their motto to the last.

KNC: We do evil well. (tm knc)

Well looks like Kncminer now is gonna get bought out. (or has been) see below from coindesk

GOOD!

Can someone see if the new owners will send over the bill of materials for a Titan? The level converters are something I can't seem to source (along with the displays), a BOM and a traceout of the board would be exceptionally useful.

Heck, I'd even tell them how to wire up the optoisolator to keep these things from blowing up.

I'll have a chat and see what's up.

I love that everyone is asking to meet their grandma, but the fact is there are no specs except dimensions and weight. It could do 3.14MH/s and need a small nuclear reactor to power it

Qberty I appreciate what you are trying to do for the community and I don't want to make you angry but my bridge board is not working. Could you post that video of how you are plugging them in. Maybe I am doing something wrong. Would not be the first time.

[Tupsu]

Qberty I appreciate what you are trying to do for the community and I don't want to make you angry but my bridge board is not working. Could you post that video of how you are plugging them in. Maybe I am doing something wrong. Would not be the first time.

Because I asked you to post here, then a little bit from you PM.

So here is what I have done in testing.

I tested the Pi. Working. Booted to a raspbian Jessie lite image.  I then reflashed a knc titan image to the micro ssd and booted the pi with just that. I can see the red power button light up.

I then attached the bridge board along with the old knc Jupiter board and the pi. Powered up and no red power light.

I have tested the knc Jupiter board and it works. Got to the web interface and the KNC logo.

As a final test I removed the bridge board on my working Titan controller and replace it with Qberty bridge board. Nothing.

So I too have a defective Qberty bridge board. Sucks. Was hoping to get another Titan controller going.

I can only tell you that you are not alone. One from B2 buyer is not  yet posted in this thread about his problem with  Qberty B2 bridge board.

Qberty I appreciate what you are trying to do for the community and I don't want to make you angry but my bridge board is not working. Could you post that video of how you are plugging them in. Maybe I am doing something wrong. Would not be the first time.

See now that's a normal claim. I'll be happy to upload a detailed video of me plugging them in and showing them working. Stay tuned for that.

I pulled out the Cristal from the qberty board and it powers up with the raspberry on it and the leds work.
So Mr. qberty your manufacture-fabric mess it up with the crystal, probably is a wrong number and causes sort to the bridge.
Can you tell us the numbers of the correct crystal that it should be there ? 
I want to order 2 crystals and finally make my 2 qberty's bridges functional.
What does this crystal do ? will it work without ?

[KNCFUN]

Can someone from batch 1 qberty's bridges take a very close picture from the crystal in order to see the numbers so i can order two  ?
thanks

[KNCFUN]

'qberty' Can you ship me 2 crystals so I can fix the bridges that you sent me ? otherwise I have to through them to the garbage they don't work without this crystal.
I will pay you the shipping cost.

[KNCFUN]

So no one says something about 'qberty'
This guy literally ate me 0.40 btc for 2 crap titan bridges. 

[KNCFUN]

'qberty' put wrong crystals so Lightfoot can't fix that.

Put him a negative trust, if it makes you feel better.

I lost 2 BTC with him, becoming 10 not working product. 

Mistakes  happen. I still believe that it is repairable.
