Title: BitFORCE SC Schematics Post by: BastiDE6 on March 24, 2019, 05:14:40 PM Hello I'm looking for the Bitforce SC Schematics ???
Is a bit older .. but was Other> Archival> BitFORCE SC Schematics & PCB by BFL Engineer Who can help me .. who has the pdfs or whatever you still have Thank you Title: Re: BitFORCE SC Schematics Post by: HagssFIN on March 24, 2019, 05:29:13 PM https://bitcointalk.org/index.php?topic=235892
This must be what you are talking about. Unfortunately I have no idea about this project. Can I ask, what is your goal with this? Title: Re: BitFORCE SC Schematics Post by: BastiDE6 on March 25, 2019, 12:28:36 PM That's exactly what I'm looking for. Unfortunately, I can not write there and the links are dead.
My problem is that I have a BF0050G where the 1 block is not running. Circuit diagrams are helpful. The User "helipotte" has written that he has the pdfs ... but unfortunately I can not send him a mail. Title: Re: BitFORCE SC Schematics Post by: BitMaxz on March 25, 2019, 10:18:45 PM It seems that almost all site that I found when searching this PDF almost died including the other links that I found from here https://www.reddit.com/r/Bitcoin/comments/1ggxi6/bfl_bitforce_sc_schematics_pcb/
The only thing that comes to my mind is to contact other members here on the forum who reply from this thread BitFORCE SC Schematics & PCB (https://bitcointalk.org/index.php?topic=235892) and maybe they have a backup copy of this file. Title: Re: BitFORCE SC Schematics Post by: lightfoot on March 25, 2019, 10:43:01 PM I have to echo this one: In the name of God, why?
It's not a hard design to reverse engineer, if your unit went dead start with the most obvious thing: The two sets of 6 FETs that step the +12 down to .8 volts or whatever runs those chips. You will probably find some of the FETs burned or blown, that's the main thing that would take these down. Do testing on the side that is up, and see if you get the same results on the side that is down.

Exactly that was also my idea ... Only I can not send a mail as Newbie and in the original forum I can not write .. so Here Now I have to echo this one: In the name of God, why?

Do testing on the side that is up, and see if you get the same results on the side that is down. How do you mean that exactly? That's how it looks at the moment ... https://www.bilder-upload.eu/bild-15ee48-1553622689.jpg.html Hello there is no one who can send the PDFs for the BitFORCE SC? Many Thanks!! Title: Re: BitFORCE SC Schematics Post by: lightfoot on April 08, 2019, 10:25:25 PM Start by looking at the two sets of 6 FETs, Q4 has one set, Q9 the other. Same as the other side of the board.
I'll bet that one of those FETs is shorted. Probably the high side ones, find it with an ohmmeter. Then remove it, and notice how the short on your 12v line is cleared. Title: Re: BitFORCE SC Schematics Post by: kano on April 08, 2019, 11:14:38 PM You'd be better to simply get a tiny UBS stick miner that performs as fast as that, but uses a fraction of the power ... is silent ... and a fraction of the size ... and a fraction of the price of what that cost when it was sold.
My collection of BFL hardware, including a Moth, is in a cupboard or in the garage never to be turned on again ... as is how it should be with old miners. |
