Hello friedcat. Stop deleting my posts from September and maybe issue some dividends instead.

Not sure who has authority in this thread but friedcat hasn't been here in a while.

The "hardware" (gmaxwell, MiningBuddy, ckolivas) mods deleted his posts for being off-topic and trolling. Comes as no surprise to me.

is this bad news ? maybe no more prismas for us ?

Also, I see movement from DHL for Batch 1 so hopefully Monday/Tuesday delivery.

I don't think you need to worry at this moment. Maybe later.

show a tracking number.

maybe they just threw the tubes to us to gain trust and now they will keep all the BTC they made from prismas pre-orders.
Shocked

It is more likely that Friedcat is leading the pro-democracy protests in Hong Kong.

Here's the data on the Prisma's fan, the PFC1212DE:

http://www.digikey.com/product-detail/en/PFC1212DE-F00/603-1164-ND/1850533

66dB, although I found a couple sources on Google that listed a "maximum" limit of 70dB.

I think Flame Sax sums it up nicely--these are serious fans.

"Mining machine at a distance of one meter, the measured noise about 80dBa."

For reference, I've seen SPTech SP10 measured between 68-76dBa. Not that I don't trust his meter, but can anyone else verify that the prisma is really that loud?

FTA: "3 noise, the manufacturers due to achieve the purpose of cooling, using up to 4.8a fan violence, including this absolutely superb cooling fan is also a first-class wind noise is also a tucao point, apply a treasure buyers tucao sounds like an airplane taking off and landing to describe though a bit too, but in the arrangement of the mine should give due consideration to this aspect, it is recommended to select the more remote places like industrial areas or suburbs."

Emphasis mine. They are using a Delta fan which are top-notch, usually loud fans. I'll go dig up the specs from Delta, but I would assume you need to keep this out of the home office.

A single USB controller can control up to 4 units (full Prisma with 4 boards). Detailed info of each board can be found with cgminer api.

Info in the OP says 8 devices = 32 units, same as with the Tube, because each hashing board has a 5 bit DIP switch = 32 different addresses.

As I tested, each prisma board would be identified as two boards (seems they purposely do this to make it compatible with ethernet controller). Also the 5th bit on switch is ignored by prisma board. So it's 16 prisma boards or 32 tube boards.
