Power supplies - fixed

In the light of the issues encountered with a limited number of the Power Supply units, we have been pushing really hard the power supply manufacturer, Apluspower, to address all the issues. Apart from reliability issues, the PSU did not comply with EM emissions, although our contract with Apluspower clearly mentioned that the PSU must be CE and FCC certified.
As a consequence, after the PSU issues were fixed, Black Arrow went through certification procedures. Prospero X-3 is now CE certified. Please click here to review the certification.
We are happy to report that according to our knowledge, testing and 3rd party certification, Apluspower have now fixed all the problems discovered and reported and we have resumed shipping. Please note that the power supply is certified together with our Prospero X3 as a whole unit and not independently.
The old design PSUs failure rate is lower than 5% and replacement is only required to comply with EU/US legislation due to EM emissions. We will dispatch new PSUs on our own cost to all customers from EU&US who wish to receive a replacement, but please note that customs duty are the responsibility of the receiver. Customers outside of EU&US will be eligible for a replacement only if their PSU is faulty. We will not be requesting our customers to send the old PSUs back.

X1 manufacturing – in testing

We have stopped manufacturing X1 and we will be shipping all remaining customers X1.5 which contains 2 chips and hashes at 160-180 Ghash in an attempt to clear the compensation sooner.
Certification for Prospero X1.5 is in progress.

X3 manufacturing - fixed

We had issues with the speed of built for the new units therefore we had to make a contract with a new business partner who demonstrated that they can manage delivery of large volume in a short period of time.
Our new partner has just finished the first batch of units which will be dispatched today and tomorrow. Their assembly speed is a clear improvement and at this rate we will be finishing all X3 deliveries in next few weeks.

14nm Bitcoin ASIC

We are still heavily involved in the 14nm ASIC project.
We are happy to report that after bringing on board more talent we have exceeded our initial 0.3W/Ghash target by 4.3 times by employing all techniques possible in ASIC and algorithm design. Our current design efficiency is now 70mW/Ghash (0.07W/Ghash) which allows us to build a 1 Terrahash chip in a single die while using 70 Watts at chip level. This will allow development of a 20Thash machine while using 1.5kw.
We intend to make this chip available for sale only from stock (No pre-orders)
