sind schon wieder ein "paar" Tage vergangen :-(

We’re pleased to bring you a new update.

Thank you for your patience! We know it has taken a while for new details to come out, and offer our most sincere apologies for any inconvenience. We’re as eager as you to bring news when it is ready for release, and above all deliver your device.

 System Update

 The power consumption of the Viper device was estimated to be 10W for a core voltage of 1.2V and core frequency of 200MHz. This estimate was based on simulation results that kept a power down feature during idle cycles for the internal SRAM in consideration. However since mining is quite the continuous activity, the idle cycles could not contribute enough for lower power needs. As such, power consumption went to approximately 18W at full speed and frequency.

As per the initial calculations, the current requirement for the core voltage was less than 9A per Viper device ( 10W / 1.2V = 8.33A ). The initial prototype was designed with a 50A power module from a leading semiconductor manufacturer for 4 Viper devices (4 x 9A = < 50A), keeping room for some over-clocking possibilities. Since the power consumption changed to 18W, the current required also changed to 15A per device which would require at least 60A for 4 Viper devices. We also noticed some voltage dips on the core voltage rail of around 200mV during the start of computation of one Viper device, this could affect the working of another Viper device connected to the same voltage rail. To cater to such requirements, single modules were pretty expensive. In order to save cost and do some more optimizations, another new design was created. It uses 15A power modules from another leading semiconductor manufacturer for each Viper device. However these devices have been behaving a little erratic and we have found them unstable during our QC tests.

The design is currently getting reviewed and failure analysis is being done by the experts at the power supply company. We are waiting for their response so we can get the correction done. A parallel design is also being done with another power supply having 20A capacity. We have tested the software, and the functionality is working properly which really pleases us. After this last issue gets sorted out, the bulk production can start and shipment will follow.

 ASIC Update

 A few sample Viper devices were tested to identify issues with PLL, IOs, memory etc. with the test vectors generated. Devices were tested and categorized into those that pass and fail. When the same devices were tested with the ZIF socket board, the results observed with these devices were different. Devices which were marked as pass did not pass the functional test completely when tested with the ZIF socket. A few devices passed the functional test with the ZIF socket board and a few failed. Test vectors were updated to include BIST (built-in self-test) to identify device which pass and fail functionally.

On further analysis of the results observed with the tester, the ZIF socket and the test vector simulation results, it was found that the tester has a higher voltage drop and configuration of Viper PLL via JTAG with the tester not working properly. Test vectors were updated to configure PLL over UART and shipped back to test house along with the devices for a re-test. By using the new test vector and increasing the core voltage with the tester, test results of the ZIF socket board and the tester started matching properly. In short, this issue is now under control and it is being worked on as fast as we can.

We are sorry shipment has not yet occurred. We very much appreciate the situation and are working our hardest to deliver the best product possible with the resources we have available.  We would like to reiterate our previous statement that all we can do is reward your patience with a product that is ready and optimized instead of rushing and then deliver potentiality faulty and under-performing hardware. We know you are eagerly waiting to get your hands on these devices, we share this enthusiasm and are quite impatient ourselves to start shipping, and hope you can understand we’re not here to take the easy way out: but deliver a high-quality well-thought of and well tested device.  We are still providing the various enhancements to the final specifications of the devices including a 10 times increase of the hash rate. We plan to e-mail all customers as soon as we have the shipping date, but we cannot estimate one at this time. All we can say is that once we have these last issues resolved and assembly has started, shipment will follow as soon as possible afterwards. We already have our chip quantity in stock, so there will be no need for us to wait for chips. That stage has now been completed.

On that note, we’d like to express our gratitude for your immense patience and confidence, and extend our sincerest apologies for the annoying delays whilst this machine is being engineered to perfection. We know it seems that every month there is delay after delay, but please understand that development is outsourced and we are genuinely passing on information we are being told by the technical teams working on the project as it comes in.

We do our best to speed the process up and finalize the devices.

Stay tuned! We hope, and are fairly confident, that our next message will be that mass-production has started and be able to inform you that shipping will be underway.

Thank you!

Best Regards

mal schauen o die hasrate das 10fache beträgt wie jetzt dann würde sich das ja wiederum lohnen noch etwa

[fhh]

das Update ist ein schlechter Witz
Die sind ja fast noch lächerlicher als ltcgear

hieß es nicht Anfang Dezember sie sind in der finalen Produktionsphase?
Und nun 4 Monate später heist es sorrrry aber irgendwie hat das mit den Spannungswandlern nicht so funktioniert wie gedacht.
Das ist doch Bullshit...

ja..... sehe ich ebenfalls so... ich bin mal gespannt wie das endet... erinnert ein wenig an BFL... mit einem Jahr Verzug wird geliefert...

[cagrund]

Gemäß Update auf der HP soll jetzt allerspätestens im July geliefert werden ... 

Gibt schon mal ein Video von einem der kleinen 50Mh/s minern. - Wobei die unübertaktet in Wirklichkeit auch nur 35 Mh/s machen. 

We would like to once again thank you all for your patience during this final period. Be assured we are near shipment with just a few more steps to finish. We wanted to give you a quick but significant update on the progress of the miners; we have completed our prototype of the smaller device. It is important to note it natively hashes at 1Mh/s per chip with 3 cards and will overall hash at 35/36Mh/s.  However, the software will allow you to over-clock it so you will be able to bring it to 50Mh/s immediately (as shown in the video). We are now just finishing work on the larger device and once it is done we will do some quick work on efficiency increases, and then we will be ready for mass manufacturing with shipment directly after. We anticipate shipment will be no later than July though we cannot promise a date yet and will update you as soon as we have that information. For now you may view a video demonstration of the 50Mh/s device and our software:

tja, es gibt ja jetzt sogar ein angebliches Lieferdatum: "spätestens Juli".... lassen wir uns überraschen

[cagrund]

So, im Juni gab es mal wieder eine News-Ankündigung:

Code:

As mentioned in our last update we are in the stages of finishing up work on the larger device before mass manufacturing of them both.
We are now able to provide a demonstration of the 250Mh/s prototype which is nearly finalized.
It is currently hashing at 180Mh/s however please note this is without it being over-clocked
which the final device you receive will be capable of; bringing it to 250Mh/s once the system cooling has been finished.

Here it is:

Once again we thank you for your patience and we will email you as soon
as we have a shipping date which shouldn't be much longer now.

Best Regards,

Alles in allem nix neues. Nach aktuellem Stand gilt wohl noch Lieferdatum "JULY 2015".

Ich bin gespannt.

Per 14.09.2015 gab es jetzt nochmal ein längeres Announcement.

Greetings Miners!

We sincerely apologise for getting this update out to you after such a long time. As we have been at a stage where we have just been awaiting system design changes and tweaks there has not been much to update on; as these have been more technical than physical so we do not have much to show.

We had originally planned to have our devices already shipped, as said in our previous update we have all our chips ready; the only delay was getting the system design so we are manufacturing and assembly ready. We had sent our system design for review before manufacturing to a UK based company who are experts in system design, they had found flaws in the system design which was made by the Indian design team. We were told if we were to take our design for manufacturing there would be serious issues. Therefore, we have contracted this UK based company to commit to making these on both the 50Mh/s and 250Mh/s systems.

The technical recommendations and changes are summarised below:

 

    Design analysis shows that the issues found can be solved by bill of material (BOM) and hardware changes. The proposed solutions need to be tested on a prototype to verify that the proposed solution is effective.

    DFM review shows that an update to the PCB is needed before going into mass production.
    System analysis shows that the Enpirion power supply can be used as an alternative power supply solution to the Texas Instrument power supply without compromising cost and performance. Recommendations for future expansion are also considered.
    Recommended that the USB port at the back of the data miner system be reallocated as a USB to serial interface. Having a freely accessible serial interface would be useful in scenarios requiring emergency recovery due to an invalid network setting rendering the system inaccessible via Ethernet. One such solution would be to use an appropriate FTDI USB to serial transceiver.

 

Towards the end of July these changes were sent to our Indian design team so they could implement them and send prototypes back to the UK based team. The Indian design team is days away from completion, once these changes are made we will start manufacturing and shipping in phases; the 50Mh/s devices first and then the larger devices.

We truly apologise for the delays and are doing the best we can to ship ASAP. We have been with our original designers from the start and it is difficult to change contractors if they have first hand knowledge of our chip and system design, this knowledge dates back since 2013 with our FPGA design. But now when we have hit the stage of the project where we have had the chance to slowly hand-over our designs to a UK based company we are seeing positive signs and progression.

When developing a new technology from a white-paper and concept, there are bound to be delays which we cannot anticipate, unfortunately we were hit by these delays. As this was a pre-order project we did make customers aware most of the work was yet to be completed. I also believe there are currently no other scrypt-based miners being shipped from any competitors, so when we do ship I believe customers would be delighted to finally have our product in-hand. Finally there is something very important to me that I want to make mention of, my intention is to try to compensate all batch 1 customers (including those refunded) in the future with our further projects.

Best Regards,

Mohammed Akram

Per 18.10.2015 gab es mal wieder neues BlaBla auf der Homepage:

Greetings Miners!

As stated in our last update, we were going through some design iterations, these changes were sent for prototyping and we have received back our prototypes. The initial power-up and testing are successful, we are currently performing some more intense testing by mining for longer durations to identify any fine tunings required. The mechanical enclosure, SOM interface board and other accessories are all ready. Once the testing of the SCRYPT boards are completed we will proceed with integration of the viper system and mass manufacturing/assembly. We will keep you updated on further advancements.

Lastly we would like to add that we offer our sincerest apologies for any issues throughout development, when developing a new technology such technical delays were out of our control. We hope to deliver a product that has no issues during operation. And would also like to state that if you feel we have wronged you in any way we sincerely apology and hope to make up for it.

Please find below the images of the new SCRYPT board and the enclosure:
