Hi,
With surface shipping and at the current BTC rate:

0.457BTC

Note that the BTC rate has taken a dive recently due to China clampdown… which we pointed out was coming a few moths ago.
It is expected the BTC rate to US$  will fall further once the mainlanders start to dump coin.

RF

Ok the rate has improved a little  0.4400BTC

Yes we do, we also employ  tracking for all products.

However we do not ship to:
countries undergoing civil insurrection
invasion
war zones
where the customs departments are so corrupt the goods do not get delivered.

RF.

Hi this is Razorfishsl,


19 port Steel cased hub with an integral power supply that is capable of reliably supplying  ~1A per port without overheating or becoming a fire hazard.

Correctly supports dual chip miners as well as Red/Blue/Ice Fury 2.6 Ghs AND Bit-Fury 4+ Ghs USB miners


This is a professional quality hub capable of 480 Mb/s  communication via any of its ports , it also complies and implements the full 2.0 USB standard.

The internal hub construction is designed to ensure the USB sockets are fully supported and do not twist/deform the internal PCB when devices are plugged into the hub.


May also be used to power Single board computers (SBC's), thereby removing the need for a separate power source for the SBC mining controller.
(may require Special USB cables to either feed power into the SBC's USB port or into the standard Jack-plug on the SBC)

Backed up by qualified engineering support including extended product support services.




Spec of product
- Fully 480mb/s at each port.
- 16 Front facing Standard A USB ports.
- 3 Side facing Standard A USB ports.

OK…..
So here we are, after my last post  clarifying the situation:

Show and tell
1. Further mis-representations: If someone came to you and asked you to setup a  system using PP split-payment API, where they received 50% of the money for physical goods they did not ship… how long would it take 'you' to setup such a potentially fraudulent system, or would you just keep dragging it out with excuses?
2. Would you setup a website on a domain name and server controlled  by a guy you only just met, who openly boasted about HOW he fucked his 'book selling ' partner over and wanted to setup a 'limited liability company in Hong Kong' with you…. ?

Personal character
2. Harassing phone calls to my mobile phone, sometimes as many as 5 a minute, because  the curtain has been pulled back in OZ.
3. A definition of what "rework" means http://scn.sap.com/people/rupesh.brahmankar3/blog/2013/07/06/rework-in-manufacturing
for those who don't understand the difference between 'rework" and Having to open, inspect, remove,repackage and test cable sets then having to completely repack goods.
4. Offensive pm's + Further falsifications (it is the first I heard….), then WHY did you state it was TRUE in your PM). (see below)


6. Yep the 'blue fury', go read up interview techniques and evaluating potential business partners, with this simple but effective test I get a complete breakdown of a persons 'claimed' area of expertise.(I could just have used google!!)
 Did it NEVER enter your thought processes of how at 21 I was the technical director of an electronics company turning over $20million a year If I was such a 'fuckwit" with electronics?
Correctable traits
7. A complete inability to articulate conversations as an adult, with valid point of contention.
8. A complete inability to get my name right..
9. The use of 'shill' accounts to promote himself in his own threads.

AGAIN I will state this:

There was a parting of the ways due to your 'business ethics' that is all, I also have the right to dispute any false statements to protect my reputation.

I think with each passing day, this conversation justifies my decision.


RF

LOL……….

Well since you have now made it a question of my Integrity on this forum….
The first you have 'heard' of this… well yes I suppose so because the correspondence was written or texed, so technically you 'read' it not 'heard' it, for god sake just man up there is no shame in admitting it.

For the record
If I had not checked and spent several days reworking those 19-port DIPO hubs that you sold on this forum, you my forgetful friend would have been royally FUCKED…

There was a parting of the ways due to your 'business ethics' that is all, I also have the right to dispute any false statements to protect my reputation.

Hi Philip,
I'm glad you are happy with your purchase.
The 19 port hub is one of the few products I am happy to leave switched on 24 hours a day/ months on end, 90% humidity. So far it is also the only hub that has not damaged my USB controller in my mac , nor overloaded the samsung SBC's I use.

But yes, your quick analysis on 'ATX' power supplies is fairly close to the mark,  anyone with a screwdriver, half a brain and google can quickly look up the specification of the  internal switching components of the ATX and  can soon realize most of the  ratings on the ATX cases are complete bullshit, you only then have to cut a wire and count the wire strands.

I have 2* 50A@5v PSU I designed for FPGA mining back in the early days and even with single strand 2.5mm2 copper( 300v mains) the wires get hot…….

Legally many ATX are just skirting the regulations for  consumer labeling requirements on honesty (in a pinch even a car engine can be started from a couple of 4R25 batteries, so technically you could state that they can supply 400A, the fact that they may melt and are totally destroyed is irrelevant)

Perhaps one of the worst things I have ever seen in  a Chinese made ATX, was a 110/220 conversion done via a diode, rather than utilize a tapped transformer , they decided to save the cost of the copper windings by using the diode to 'clip' the mains cycle by 50% producing a shitload of heat and more filth(EMI) than a german porn movie.


I've been less active on the forums recently due to new projects and  hope to post some new designs I have been working on that will further enhance the lifetime of the 19 port hub with the new multi chip bitfury miners.

But basically unless I have 100% personal faith in a product I will not sell it.

RF

Why go all the way over to that thread, when I can supply exactly the SAME product that has been professionally tested by Qualified engineers?

Just PM me for a quote

LOL….
Before we start handing out accolades for quality
Can I clarify something  once and for all, the 19 PORT DIPO hubs that were 'sold' were actually from a batch that was TESTED, Inspected  and REWORKED by ME!!

RF




No it does not, I am 'intimate' with the design of this hub.

RF

I would say no….
there is no credible reason to make a 'live' copy of another website, unless your plan is to leave it a few months then start injecting malware, or worse you get fed-up … loose control of the domain name and then the ass clown domain miners take over.

ILLEGAL WEBSITE.

NOT LEGALLY REGISTERED TO DO BUSINESS IN CHINA, POTENTIAL SCAMMERS.

LOL  that is some funny shit, my mis-spent youth flashed in front of me.

In many cases you will find that  over volting/ increasing the frequency will eventually result in less shares at the pool even if the error rate does not increase.

It seems counter intuitive to increase the voltage/frequency and get less out of the device, but that is what happens due to the way the silicon is designed and is due mainly to race conditions inside the chip.

Also most mining programs can be wildly incorrect with their hashing rate calculations  due to the way they have to calculate the figures, they can only base the rate on when they get a reply from the miner (
good or bad)
Then on top of that you have shitty little cutter SBC's that cannot get round the full USB chain before results start to lap.

Generally it is a balancing act where it is better to go for increases at the pool rather than hard local frequency increases.

The only issue is not trashing the silicon in the process, because getting your device back to the factory for repair will be a real issue. (It is almost impossible to get product back into China cleanly)

RF

Yep,
It once again highlights why buying Nand flash  sticks in China is a high risk proposition, I just wanted them for the  viri they come pre-installed with.

Also if during your research you find the hub won't power the PI due to the power requirements PM me directly I already have a solution.

 I've been working on a Quad core mining controller which I finished the new kernel build for a couple of days ago but I also ran into issues with peak current consumption.

RF

Hi,
Glad you received it in good condition and  I see it is performing well.


Yesterday I was working on a new project  using this hub and a some flash drives i purchased in China over the weekend
 I'm thinking WTF is that burning smell, but put it down to the locals roasting some cats on the BBQ's they like to have.
Nearly an hour later I identified it was from near the hub, tracked it down to one of the USB flash drives.

Opened up my hub expecting to see something burned as well but there was zero damage, the poly-fuse had cut in and protected the other devices, power supply and PCB (that's the hub pcb)

This is the second time this month that the hub has saved me a shit load of heartache, the first was on a load of USB->Ethernet adaptors, where they had wired the  power rails backwards!!!!

Normally with such failures on an "ebay hub" you would see the PSU dump the whole current onto the faulty device until  the short is burned out!!
Which results in all sorts of damage and possibly a house fire.




When you consider how many USB 2.0 hubs you purchased over the years , plus considering this hub has a life expectancy of years it really is good value for money.

Plus with this hub you can power a PI from it and mine all from one power supply, instead of needing a separate PSU for the PI

As Guy Kawasaki pointed out "you can compete on price or quality" ;-)

RF

Yep…….
Let us not forget that even inside a VM any  virus/exploit is already BEHIND your main defense and can easily access the ip addresses of any computers on your internal network(not to mention default passwords/access on your router!!)
Including the machine the VM is being hosted on…(not much point in having a DMZ, if you are going to put shit inside it…)
and that is before we even consider the capability to  crash 'out' of a VM.

This is the result of teaching liberal arts at school…. many people seem incapable of thinking more than one move ahead.

Still have some hubs available on the original thread here:

https://bitcointalk.org/index.php?topic=413406.msg5421333#msg5421333

you can PM me directly for discussion.

Been busy on some new mining products.

 Feel free to do it any way you want. ;-)

The only matter I would like to clarify , that there is no connection/ responsibility between  different people shipping product from HK.
