The main shitty thing about Labcoin is that they seem to be incapable of answering ANY technical questions asked about their chips (even though they promised to have lead developer answer questions countless times).

How come we haven't seen anything what the PCBs design or the development of it looks like? since theyre only going to sell chips what is the harm in showing us what the PCB used for their own farm will look like? A first version of the PCB design must have been ready for weeks.

How are they planning to remove all the heat the chips obviously will generate? BFLs 65nm chip has about the same power draw (~12.5 Watt, and everyone know how much it takes to keep those chips cool, and their chips got an exposed heat pad.   


Compare this to how transparent Friedcat or Bitfury were doing the development of their chips... 

https://bitcointalk.org/index.php?action=profile;u=49840;sa=showPosts;start=180  - Friedcat keeping investors up to date every step of the fabrication process with very technical details
https://bitcointalk.org/index.php?action=profile;u=58469;sa=showPosts;start=360  - Bitfury (google translate russian posts)

They've already had one Q&A, in IRC. They are supposed to be getting their PCBs soon, and presumably will post pictures when that's done. Obviously their priority is getting their chips up and working, not answering questions in a thread.

If you had attended that Q&A yourself, like I did, then you would know what a joke of a Q&A it was.. It was basically an assistant to the developer copy pasting publicly known data.

from vbs: "For that to be possible, not only each Labcoin core would have to be ~42% smaller [65/130*(6.5^2)/(7.1^2)] than each BFL core but also the Labcoin chip would magically operate at a higher frequency (300MHz vs 250MHz) while keeping the same power draw..."
i remind you guys that the bitfury chip has up to 750 cores
how many cycles per hash?
they also use the same approach, we chose this design because one of our guys was close to bitfury developments 2 months ago
how many cores on average per chip, what is your assumption
i'll  pass the questions i can't reply to the lead developer
--> hammurabi (~muaddib@93.179.239.13) has joined #labcoin
<-- eleet has quit (Ping timeout: 240 seconds)
After this Q&A is completed, can you take a couple of photos from your lab environment  / screen shots on chips software and upload to bitcointalk thread or for one of us to upload if you dont have permission yet?
i am not familiar with such low-level details, sorry, i will get a detailed reply from the lead dev about this
