bASIC graphic renders and diagram

Hurray for Solidworks mechanical renderings of an electrical system.... where are the electrical pcb renderings?...

Are the colored things at the bottom seriously LEDs? 64 of them? I might not need a Christmas tree if I can get one of these by the 25th

I haven't publicly laughed at the amateurishness of the 'renderings' yet, so...

BWAHAHAHHAHAAHAHAAHHAHAH!

Oh that's precious.

Thought I'd repost these here:

Feel better?

As I don't intend to mine with renderings, I'm fine with amateurish pictures, just put the real thing in a box and ship it to me.

180mm = 7.087 inches. Now that's a cooling fan.

The fans don't seems to extend the full 7", so I'm going to assume that maybe it's 4x 70mm or 80mm fans? I'm assuming you could replace them with a larger 140mm fan, but like I said, it wouldn't cool the center ones as well.

Would it even need a fan at all? Say its 120watts and 16 chips, thats 7.5watts per chip. Wouldnt a heatsink alone be enough to keep them cool?

Consider it this way: the current MMQ has 4 chips, and pulls 40W. Even at 10W/each, they have a heatsink with a built in fan for every chip. Lowering the thermal output by 25%, but then sharing one larger fan between 4 heatsinks, would be about the same.

Thats true, I guess I was comparing it to the 5watt that the rpi uses. Although the probably would not be used in a situation where it would be maxed out for extended periods of time like an ASIC will.

Clearly.

Last spec update I saw had board size at 7"x7.5"x2.167" for 72Gh. Given that we're talking about 16 90nm ASICs on that board I believe that to be very reasonable, but YMMV.

7" x 7.5" you say?

Yes, that's so compact!

and so obviously efficient!

I don't consider compactness to be very important for this product.

If they reduced it to a 3.1337" board, and it delayed the shipment by one day, that would be a trade-off not worth making IMO.

The whole Rpi uses 5W at max load. Just the SoC does not use quite that much. These chips themselves will be using a min of 7W each, and they will be at max load 24/7.

Quoting that in case you're wrong later. 7w@16 chips = 112w. If the rest of the circuitry and perty perty blinky things consume 8w or less that would put bASIC01 within it's stated power consumption envelope. I can definitely live with 72Gh@120w, particularly if it ships in January.

I'm glad you can,I can't.But I may have too,If BFL dosen't deliver or screws the pooch like they did with the FPGA power consumption.

I have a bad feeling they underestimated & won't say a thing until the last minute,like this chip delivery crap 

I was in on the BFL Single orders,but late enough to not feel the late shipping prob.This ASIC thing is almost the exact same scenario of the FPGA fiasco,go figure
