Topic: I no longer work for Butterfly Labs (BFL) - page 3. (Read 21127 times)

The Habanero actually has 4 6 phase VRMs compared to 2 6 phase VRMs on the Monarch.  Each of the 4 VRMs are tested to 300A but only operate in the 100-150 amp range.  If you have a copper trace with .0001 ohms of resistance, 100A is 1 watt of power loss, 150 is 1.25 watts.  Compare that to 300 amps... 9 watts of power loss.  So the Habanero has 4-5 watts of heat compared to 18 watts of heat if it's traces have the same resistance as the Monarch.  Then compare the voltage/resistance to hit the amps... R=E/I or .9/100-150 (.006-.009 ohms) vs .6/300 (.002 ohms).  .0001 ohms is 1.1-1.6% added resistance compared to 5%.  .9v becomes .909-.911v compared to .6 becoming .63v to get the needed voltage to the chips over the added resistance line.  More voltage becomes more heat, more heat becomes more resistance, more resistance becomes more amps... Designing a .9V VRM is much easier than a .6V one.

Excellent I wish I saw this before.  Great link to be pinned on top of the forums.  I recommend manufacture complete name be used accompanied by their abbreviation.  i.e. Butterfly Labs (BFL).  I just sent PM to Dogie for this tiny edits. 

Thanks for the link Intron

Absolutely I appreciate the question specially by senior members or moderators such as yourself hopefully to make possible tweaks for future customers. But first little demographic about myself: Technologist, software architect, robotic hobbyist, internet sway, and reverse engineer, and of course a crypto currency fan as of 8 month ago.  

I am dumb but not too dumb nevertheless fell in Butterfly Labs trap for following reasons:

 1- I did research them for scam including most other big players. They all equally had several # of complaints, but I didnt find major law suites that I could pin point or they all had similar allegations.
 2- BFL was located in US.  I figured worse case scenario I be dealing with a company in US than China or Europe.
 3- I noticed many good reviews on BFL Singles on youtube, and even saw ads such as this one that they being sold in retail such as Tigerdirect & Walmart.  For example see this one: http://www.walmart.com/ip/34952957?wmlspartner=wlpa&adid=22222222227023099684&wl0=&wl1=g&wl2=c&wl3=36174013381&wl4=&wl5=pla&wl6=65388671101&veh=sem
 4- They accept USD, in addition to Bitcoin.  Most others would take bitcoin which I didnt have.


What I didn't know or just realized several weeks ago was the fact that they pocket 99% of funds received and allocate less than 1% to development, which is the reason for super late development.  I used to think the complex technology was a contributing factor, and didnt know they under fund development.  Also I didnt realize their board members are bunch of Jackass running ponzi scheme with hardware.

I even searched top 10 bitcoin miner in google and landed in PC Magazine or Toms Hardware and BFL was right on top.

I think what this forum or similar could do to help is a recommended manufacture link and rated by trusted senior members like your selves.  I am sure such link probably exist but perhaps buried or crowded with many posts.  I guess clean list of scam alerts for member and or manufacture, that is easy to locate would be very helpful and could reduce number of people falling in this trap.

I am also twitting some of my findings to reporters who apparently interviewing BFL and using appropriate # hashtag to help expose these jackasses whenever I get a chance.  As you would see in Josh twitter.  However I am doing it based on facts also copying FBI and KC police, in case they actually read the tweets.

Hope this help.

Thanks
Sean

Habaneros are capable of pulling about 800W readily, with around 90% efficient phased VRMs outputting around 900mV. Assuming 90% conversion to 0.9V that's 800A of low-volt DC. 300A at 0.6V isn't actually too hard to pull off reliably. Just saying, but every other ASIC manufacturer has accomplished that or better in a heck of a lot less time.

Sean you are obviously newish here I'll assume by activity.
Did you choose BFL because all the posts/threads/everything on forum was hidden, moved or deleted.
Not being negative regarding you, It just would be good to get clear clarification that the forum could be doing alot more to assist people in not getting screwed by these people that have been running the same trick for what 1.5 years now ?

I know the forum doesnt hold peoples hands... but jeeesus christ. come on.. help a little...

Exactly, Yep, I mean no magic tricks or fake videos etc.  I dont have anything against their technicians or employees, they are just doing their job.  But their board of directors are bunch of tricksters.

I believe you are meaning to use the metaphor "smoke and mirrors".

I encourage BCP19 to help uncover BFL mysteries and scams. All these HW operating #s probably meaningless if this Monarch turns out to be an imaginary development or smoking mirrors.  FBI knocking on doors of BFL, Josh, Nasser is RSN any day now.

I think that the Habanero is running 600+ watts through a single board. 4 6 pin power plugs.
It gets pretty dang hot.

Just as a comparison.

Thank you BCP12 for this bit of information.  Josh has failed to provide any tangible proof of actual development perhaps because he doesn't know how to make walk through video but he and Nasser are good at login in as Slok in BFL forum banning and censoring legitimate customer questions or login as fake customers almost as if they are playing with themselves in public forum (BFL forum).

I am EE myself but I have ton of respect for Technicians because many of my own techs are 100 times smarter and sharper than myself. Do you think you would be able to post a walk through video of working monarch to ease some doubt. Walk through video is simply connecting unplugged monarch, plugin it in, and start hashing while being followed with a simple cell phone video? 

I afraid if BFL can not even make descent walk through video as a proof of work, how the heck they are building this Monarch.  Hopefully you can ease some of these questions.

Thanks,
Sean

The fact is BFL has lied and lied and lied. THIS IS A FACT
Some Ex staff member comes here and tells us possible things that have been going on for the last 10 months,(You have agreed are partially true) thats much more than BFL has told us with there lies
And Bfl expect us to believe them now,
 Come clean and show us what you have been doing for the last 10 months with all our money and stop the lies

reserved

So you still don't have a handle on the heat dissipation on the boards yet?  Thanks for sharing that development tidbit.

Looks like Two Weeks™ then.

Good to know that BFL's top asshole shill PCB technician/engineer is on the job, working tirelessly to ensure "the problem..." gets solved as quickly as possible*

_{*When he isn't trolling the fuck out of bitcoin forums. One must set priorities, after all.}

Yes, we are trying to finalize development now.  dropt has said he's an EE, so this is for you:  I'm a tech, not an engineer, I test and troubleshoot, I don't design, I may not know the 'PC' words for this phase of development.  I will give you this though... 300 amps at .6v... maybe now you understand the problem...

Bunch of kids running a lemonade stand are not plagued with greed. If there is a monarch, and I do not doubt there will be a piece of shit in a box labelled a monarch, it will take an extreme amount of time to receive, while you watch Josh's online circus. But don't worry, they usually give you some type of coupon on their next piece of shit in a box.

… in the end, its all smoking mirrors man.  

dear BCP19 Is there actual Monarch under development or is this whole thing smoking mirrors? When I asked Josh to post proof of work, he simply banned me from BFL forums.  Apparently using logic is not a correct method of communication with bunch scam artists.  They advertised this Monarch thing 2-3 month away from production, 6 month later your company "Butterfly Labs" only produced a grainy video.  Josh latest update is on the plane... probably taking a shit in first class cabin.  Could you please provide useful information to prove there is an actual monarch development? Bunch of kids running lemonade stand would have completed this Monarch with sum of ~$100 Million received. I also think your bosses pocket around 99% of the funds and allocated around 1% to development that is why this development taking too long and or havent been able to hire talented people to actually roll this out of production.  Any valuable information from you will be helpful.

Thanks,
btw, I am an actual customer who paid real money for this Monarch.

Hi,
Around two weeks ago due to lack of update from Josh aka Slok, I become suspicious if only fraction of percentage of money received by BFL allocated to actual Monarch development or even fake development. The reason for this was, after almost 6 month, I havent seen any sign of proof there is an actual working monarch other that grainy video that could easily be forged.  When I asked Josh/Slok in forums to please provide solid proof of work, they just banned me.  Since you worked there, could you please confirm to best of your knowledge if there is an actual working monarch card or did they just develop chips ? Do you think their cloudmining is being done using actual monarch cards ?  Any information would be helpful.  We spent ton of real money for this stupid thing and the only update from Josh is he is on a plane and probably taking a poop in a first class toilet.

Thanks

Allowing them to advertise here is a much worse things to do than having no scams threads in the Hardware section, but you have a valid point even if the BTC isn't well past redemption. BTC will live no matter how many Inaba tards there will be out there.

No wonder BFL and their brethren are able to operate. Critical posts that (exceed a certain threshold) about hardware companies end up moved away from the hardware forum.
Talk about selection bias. Hardware companies accused of being scams get moderated back to legitimate status.

Newbies will visit the hardware forum, see no threads about scams and think everything is safe and sound. Not that it matters at this point, I think the bad actors may have poisoned the BTC well past redemption. Time will tell.
