FC seems to no longer be fulfilling AM's most basic obligation to their original shareholders.   

XPOST of interest to investors in ASICMINER and its subsidiaries/partners/products:

OgNasty, where you at?

I'm waiting patiently for confirmation that shares have been transferred so I can make the final payment.  I offered to send 0.75 BTC now to satisfy the agreement in exchange for assuming the risk of AM not paying out or confirming the share transfer.  I am still happy to do that, or we can stick to the original agreement and wait for confirmation from AM.

Friedcat is a scammer if he does not honor his promise to transfer shares upon request.

We risked our BTC to make him rich and famous.  And now he's too busy being successful to spend 5 minutes dealing with an early investor?

If Friedcat breaks his promise to confirm share transfers, I hope the Chinese Scam Police hunt him down and teach him a lesson.

Do anyone have some support about prism in last week ? mayby they dont answer only me :/

[Vaskiy]

still available? 

[takagari]

Did these guys fold up shop? lol

[sidehack]

Probably talk to CrazyGuy, I think he's selling Prismas.

update :

1. We have lost contact with Friedcat more than 40 days, we are now still focusing on finding him.
2. A lot of evidences we have found shows that he is safe, which is the only good news recently. In addition, all rumour around the community are baseless and untrustworthy. We know so far nothing about where has he been and where is he at the moment.
3. We have to focus on finding him currently so there are indeed some delay on replying email of sale@bitquan.com. However, since we have all records of your emails so it is only a problem of time, please understand and be patient.
4. AMHASH project is not from sale team of ASICMINER, we know nothing about the deal between Friedcat and ROCKMINER, no one else has seen the contract between them either ,therefore, we sale department of ASICMINER is not be in charge of AMHASH project, please be patient to wait till we find FC.

So we're to assume friedcat is dead?  Because there's Tor and VPNs to update with a simple "I'm alive." email, which, if not sent...

Not to say he's physically no longer alive, but that the alter ego of 'friedcat' in and of itself is effectively gone...

So Basically The company is a shit show, falling apart, and no one should give these guys a penny ever again.
Interesting.

did fried cat apear or is dead?)

[notlist3d]

did fried cat apear or is dead?)

I wondered this aswell.  If he now lives on a island enjoying life, or if hes back in bitcoin somewhere.

Would be interesting to know.

Despite of us who can be robbed scammed from companies all over the world CHINESE comrades never forget
I guess he missed to pay to someone and who knows what happend...
Same will happen with bitmain sooner or later. Comrades do not care if btc Is 1k or 1 euro. They want their money and unfortunately there are no chances comrades to be scamed

[Niggle]

Where can i buy a prisma?

[TheRealSteve]

Where can i buy a prisma?

try marketplace? maybe amazon / ebay?  they're rather old and not being made anymore. consider first if you really want one

[CrazyGuy]

I've got two Prisma 2.0 units available. 1BTC each, shipped

[DanielRo]

I think you are right.

Hy, i want to share some opinions i have discussed with intron regarding the undervolting of the prismas.

What he told me is that being a one string design meaning that each row has 16 chips @12V that is 0.75V.

In order to undervolt you would have to come down from 12V to 9...10V that would give 0.65V to each chip.
Also those D15NF10 mosfets act as a shunt when a chip in the string goes bad, alowing the string to keep going,
but here comes the bad news, if a shunt is activated there are 15 chips in the string, that equals to 0.8v/chip...more amps being drawn...

From the pictures and calculations and after doing some numbers, those mosfet are working @20~22A, maximum amperage is 23A
If im right then in all the cases a board caught fire was because of a bad chip going wrong, shunt working and the mosfet exploding because it was to its limit.

Its a good design but poorely equiped.

A question to the ones the board caught fire: Were they powered from Server PSUs?
Server PSUs are known to be more stable on the 12V line, normal ATX would go down to 11.8v or so no resulting in such a bad avalanche heating disasters.

What could work is modding a server PSU to 9...10.5V and powering one blade to see what is the maximum clock it would go and power consumption.
It will make the blade safer and power consumption will go down.
OR
A rectifier 30A diode with a 2.6...2.8V voltage drop on it in series with the whole blade in order for the blade to work undervolted with a standard 12V.
The goal is to make them safer in the rectifier diode situation. Power consumption will not go down so much as the rectifier will dissipate about 50W of heat.


All i said is theory, until my blades arrive and i can send one to intron or test myself.
None of this has been tested or we could be dead wrong about the design.
Please test at your own risk.
