Excellent news! Please don't hesitate to drop me a line at [email protected] if you need a hand with anything else.

Got them working!  win7 BFG 3.10    4 yellow jackets stable 2.5gh/s at osilator 54   Fantastic product
!!

Hey Zip,

Sure, what OS are you using?

hey bitgtr do you know anything about getting the yellow jackets to run in BFGminer 3.10? they run amazingly well in cgminer but would like to use BFGminer

As a matter of respect, I would ask that you please do not to mock up my board. It is based on the NanoFury NF1 v0.7 board; the only differences are a bit of extra blank PCB on the sides and the silk screen, both of which are purely cosmetic and were changed for me by the originator of the project, vs3.



Since the project is completely open source I would be unable to "steal" it, even if I hadn't worked closely with vs3 on it. It is publically available for anyone who wants to use it. Also, if you look into the project files you will find that there are traces of customisation specifically for bitgtr.com. You can find out also who did the customisation in question (hint: it was vs3).



Designing a new board takes some time. For example, I worked with vs3 for over three months to bring the Yellowjacket to market, and before that it took him two months to finalise the design for the NF1. However, since you're interested in multi-chip designs, here is a spoiler of the NanoFury Duo (a.k.a. NanoFury NF2):

Actually if you want me to make a mock up of the board I have, there are drastic differences between the posted NANOFURY board and the BITGREFIED board in my hand./


Did you steal a board spec, modify it for the chip reel you bought, and try to profit off it?

If so thats stupid, why not do what you said in chat and design a board to house MANY chips.

Or was that all speculation cause the chip reel you purchased has been spent on the 3k production of the current yellowjacket production?

You dont have any more asic chips to produce a second run of larger chip density boards like you claimed in chat, do you?



Just debunking ass holes who profit off us here is all, not really looking to scam anyone after I been scammed 6+ BTC in my life (and made half that back through legitimate trading!)

3.5 v hub

ALSO What version of the board is the current shipment based on?

I also stated not all devices would be broken.

You're stating 1.6 is the base speed not the 1.8-2.2 in your sales pitches?

You did not update paypal tracking info to reflect a proper return with open claim.

I do not wish to tamper with this device prior to paypal clearance of dispute.

You wanted me to ship the devices to some address in au when the original shipment came from SHENZEN

You issued the claim that I was somehow at fault prior to any acknowledgement of return of goods.

I had been in prior discussion to supply these devices to the community at no profit model and ultimately delivery to new miners as my intention.

After disclosing my issues you somehow came to the conclusion a potential no profit supplier was trying to scam you and defraud your name.

I do not wish to defraud or scam anyone. Your devices are defunct.

Has ANYONE had issues with 1 to 3 units of a 2.2 usb miner on the specified DLINK hub? Not that I can find in google.

If your device does not claim more power req than a BE, then has anyone with 3 block erupters in the same DLINK hub had any issues?

My BF's mentor is dealing with a family situation and cannot address this issue. I don't blame him.



Fact is hub is fried, devices dont operate as specified in hub or usb port && vendor was a giant asshole in cordial communications leading up to a paypal claim.


If you have working yellow jackets, kudos, you got the few in the run that work.

If you are planning on buying, please wait until my paypal claim is finalized to make your judgement. Honestly there is cheaper mining out there.

How much does 2.2 GH/s on CEX.io cost? Cheaper USD than these devices.




Jonathan, I am a nice person, that had legitimate claims, that you did NOT wish to address. As a potential reseller your attitude towards me is less than what a respectable business relationship entails.

Good luck with your financial endeavor. You do not have any vested stake in the R&D  and merely purchased someone else's design for profit off the crypto community.

Did you realize your CHIPS were "worthless" before or after you invested?

it still sounds like a bad hub, like a 2.5v which wouldnt support that many yj and if OC they take more power. I have my OC to 2.7. You cant just plug these things into a cheap hub and expect good things from this. This is a crypto world where everything is voltile like the currency. This sounds like a user fault, trying to blame manufacture. Just my opinion. I will gladly "test" your Yellowjackets for the next 3 months and tell ya how things are. I made an account just to post this. It seems you got angry cause you couldnt figure it out. Started raging and flaming. Instead of looking for insite you looked for a fight. I prefer the YJ over ant 1.6ers. Stock faster, OC to faster and the dude selling them is quite alright in my book. If ya would have taken a second to look information up on hubs. Dlink from my experience has been a dud.  Have fun with the tech.

I got a PM being asked to comment regarding those pictures:


Those are pins 1 and 2 and they are all connected together along with pin 3 to the ground plane. So in essence that "shorting" is there by design and cannot lead to the issues being described.

Below is an older drawing from my original group buy showing the area in question:

Look at the lower right corner of the chip. That's the previous version (0.6) of the board but that area has been the same since version 0.1 and was not changed in 0.7 (which is what you have).

Hello all!!
  I recivied my 2 yellow jackets that I ordered from hash rate store in dec.  they are hashing great! 2.5gh/s on all of them stock settings in cgminer! Fantastic product!!
    Thank you for all of your hard work on producing these miners!
I definatly recommend these usb miners! and will be ordering more soon!

I'm very sorry to see you're still having troubles; as you mentioned yourself I'm more than willing to help the beginners with setting up and troubleshooting their devices. I also offered you a full refund on three separate occasions, all of which were refused or ignored.

We strive hard to keep our customers happy, so I would be glad to do anything else within my power to resolve the problem.

As for your specific issues, they seem to be isolated to the second-hand DLink hubs. There are numerous posts related to issues with them - just do a quick search on the forums. The "shorting" you're referred to is certainly not the cause for your troubles; vs3 has confirmed those pins are bridged by design. Each miner is tested before shipping, so I'm confident that the Yellowjackets you received were fully functional.

Finally - now that you have decided to open a PayPal dispute instead of accepting my refund offers - can I have my devices back?

The antminers are 1.6GH/s stock (so +-10% in reality) and can be overclocked up to 2.2GH/s; the Yellowjacket is a tweaked Nanofury and runs at 2GH/s stock (again, +-10%), it can hit 2.6GH/s safely when overclocked. I've had users reporting up to 3GH/s when maxed. They also make use of HIDAPI and so don't require specialised drivers, as well as being easily overclockable in software (just change the oscillator bits upwards from 50, as opposed to having to enter a frequency). Antminers are also less efficient than Yellowjackets, requiring the same 2.5W/0.5A per unit but offering a lower hashrate.

The choice is of course yours - nobody's forcing you to buy my wares   

I got 2 Yellowjackets this week and they are running very smooth! At first I had some issues on my RPI, but after some fiddling with the settings they work awesome (even uncooled)


NF1 = Yellowjacket.

What hub that isn't so expensive it offsets the cost of the hardware itself, would you suggest?

Is not this hub one that has performed consistently great for the community?

http://www.dlink.com/us/en/home-solutions/connect/usb/dub-h7-7-port-usb-2-0-hub
    Standard Mode:
        All seven USB ports- 0.5 A per port 2
    Fast-Charge Mode:
        5 standard USB ports- 0.5 A per port 2
        2 USB fast charging ports - 1.2 A per port 2
PSU for HUB: +5v, 3A

So you are telling me this hub is the reason the yellowjackets ic shorted and caused a bridge in the soldering? Please clarify on your intelligent retort. Any reason as to why you stated the hub was the point of failure would be appreciated.

Is it from experience?

In what?

There are units being used right now that have no issues. I am not saying that they all have issues, I am merely saying if they do, which mine obviously do (with testing being done today for proof), shouldn't a business man want to figure out the problem

...My interest in this is to make the device work.

I had hoped to propagate these to many communities both versed and unversed in crypto, but given the business attitude of the original reseller BITGTR, his methods should also be called into question. I do not need to make money off these devices as I make more in trading daily than I make mining yearly.

This community is fraught with mis-info, false claims, and hyped up bullshit. This is the nature of greed, yet the face of it speaks to profit hungry daemons.

If the above sentiment is a vendetta then the English language needs to be updated.

edit: typo on the pun, go figure. Nothing is perfect LOL

I spend time on D7 and cryptolover has been spreading her views on Yellowjackets there as well.
As I also purchased YJs, I got a heads up from OP as to that allegations would be coming.

When my YJs arrive, I will fill you inn on my experiences.
Just be warned that these informations may be fueled by a vendetta for separate reasons.
I am sure OP will get involved when he notices the activity in this thread

I am pretty sure they will blame your hub. 

I purchased three of these units after speaking with BitGTR owner (name omitted) for the last few months.

He approached us in D7 pool chat for ppc mining.

He made the claims he was intrinsically involved with this device and its R&D.

In chat it comes out he is merely the financer of the project that was started by someone else (I've forgotten his name as I've never spoken to him nor seen the threads about the development of this project before it was taken over by BitGTR).

Upon receipt of these units, I promptly followed the directions on the website (bitgtr & hashratestore) ie plug-and-play with automatic detection in either popular mining program.

Nothing identified - nothing hashing.

I contacted Bitgtr & then tried to troubleshoot. Replacing bfg with cg, installing into a different OS (windows v linux/rpi) and tried again.

This time they did recognize after a bit of tinkering with settings in windows to acknowledge the correct driver for HiD as specified (also not plug and play for me).

I saw them hashing at 1.7-1.8 and walked away. 10 minutes later they were running great 3 yellowjackets on a dlink 7 port hub.

I'm watching my hashrate on the pool server and notice all of a sudden it drops by 1gh/s after 15 minutes.

Then slowly it starts dropping by .1 GH/s at first, then .2, then all of a sudden they just stop.

One thing I noticed (I'll post screens later) is they say CLOCK frequency dropping by %50 reinitializing. This doesn't happen for at least 5 minutes, then it starts happening at increasing intervals until it finally fails.

After they were tested twice to perform in the exact same way, I thought to try it in the USB port on my laptop. Same deal. It starts a bit higher at 2.1, then has the same exact issue. Slowly resets the clock/reinitializes until it no longer is recognized.

After this I think, if the power requirements somehow were 'unhinged' and keep doubling, or halfing, or shorting, perhaps my hub had issues? I tried 5 block erupters and after the 3rd one plugged into this hub would disconnect the last one plugged in, Plug the fourth in, only three show up, plug a fifth in, that one recognizes and the first one is removed from the system devices listing.

The hub had fried.

I bought another DLINK hub as this hub has served me with 6 BE's plugged in hashing at 334 continuously for 3 months. I had purchased it used. Maybe it was just its time.

I plugged only one YJ into the new hub and the same issue resulted. I unplugged it before THIS hub fried. I tested the hub after and 6 BE's work in it fine. The old hub still has the disconnect issue AFTER the yellow jackets were used on it.

I had been in contact with BITGTR and was asking for a refund including shipping. He did acknowledge that he would accept returns but at a different address than the shipped address, and he would only reimburse me after he received.

He did not want to push this return through paypal, as I would be protected in the case he did not wish to refund my money and I had shipped the item back.

He never entered tracking information into PAYPAL to corroborate the shipment, therefor no claim for RETURN could be made. After I had been mentioning my issues with hardware, and asking cordially to find an answer he told me:

" I do not wish for you to be a reseller of my item "

This is fine, but it only comes after he dismissed any claims his item could have damaged my equipment, or that oversight in Shenzen manufacturing could somehow be flawed.

Upon closer inspection I found this (picture). His dismissal of my re-selller status came only after I mentioned this shorted pin, and that my boyfriend could fix them and help troubleshoot.

I mean, what are initial buyers/testers for, right? Well I was sold an item that was proposed to have decent R&D/QC/Troubleshooting support, yet the seller is hesitant at best to make these work on very popular mining gear. It was also noted that initially BitGTR made the claim that although dozens of units had shipped, I was the only one to have issues.

I was order 0012 in his invoicing system. Out of 3000 units if 3 are defective (at least), what percentage is that? I would be hard pressed to believe this figure was the maximum defect allowed from QC.

After mentioning the shorted pin to BiTGTR he not only dismissed the claim that it COULD be the fault of his miners, he mentioned that the device was DELIBERATELY manufactured this way. Anyone with soldering experience can see this is an arbitrary pin short and if two pins were indeed to be soldered together, they would have a joint pad on the board, not soldered above the pins. The corner in which the two pins are crossed does seem suspiciously close to other components.

Perhaps the manufacturing process is slightly off, perhaps my hub just wanted to die and take out three yellow jackets.

My bf's electronics mentor is coming by today to check it out, tinker with one unit, and help us get this working - with opposition and no help from the seller.

Buyer Beware.
