Looking at other options.

My sons' laptop, for example, has 2 usb ports virtually atop each other.
If the USBs were oriented in opposing manner, the boards would face each other, and the heatsinks would face away.

As S2s stated, I can just get USB hubs.

But that solution has me thinking...

Earlier in the thread, we discussed that the Avalon chip draws too much juice to put >/= 2 chips on one USB miner.

How, then, do USB hubs get around this?

In friedcat's Eruptor thread, there are a bunch of Eruptors ass-jammed on a USB-hub...

How can the hub handle the power draw, but one USB connector can not?

Just get usb extension cables if you are worried about placement!  Much easeir than having 2 different usb stick styles or heatsinks etc.

Hes probably wondering how to get 2 of them on ports that are next to each other such as a laptop or pc. If they are oriented in the same way this is impossible without a hub or extension.
yes!
The heatsinks would get in the way.
The solution to this would be to make them longer but narrow so that the whole unit is as wide as a USB port (1/2" roughly). Is that a format people would prefer? I think it could be done but may need a taller but long,narrow heat sink.

(I really think if you want many of these you would be better looking at the K16 board. I'm pretty sure that they can be filled with less than 16 chips, but cannot say for sure until Avalon docs come out.)

Is it possible to have the USBs in 2 different directions?
A 'normal' and 'goofy'?
I don't understand the question.

Rotate the USB plug along Y 180 degrees

So you can fit two in a pair of USB ports next to each other. 

Another option might be a short cable.  Wink

Here's my first pass on the Klondike 1 PCB layout.

Prettied up with designer colours.

Board is 1" wide and 1.5" long with USB tab sticking out about 0.5". I just realized I'll need to flip over the USB tabs so that the heat sink is on top. No worries, always stuff to fix up, but lots of time before any chips show up. This will run the same firmware as I'm developing for the Klondike 16 and 64.

Also noticed I lost some thermal vias during the copy over from 16 chip board. Ha ha, I was going to redo them anyway. It's just a quickie to see how it'll fit together.




Bkk,

Think. Positive. Thoughts.

I've been tinkering with the 3D rendering in Kicad this morning so people can see what this could look like.

My current projection for retail price is $16 for a kit, and $25 for assembled - both NOT including the ASIC.

Please consider doing a 2-chip version. Downclocked to 256 mhz would be a really nice usb stick.

Pipedream, but downclocked via. USB 2.0 / standard clock via. USB 3.0. would be awesome.

Will there be no option to have a ready to mine option? to save extra time and shipping with me having to source a chip to send to you.

I probably want atleast 2 at these prices. Will there be an option to pay in BTC ?
Probably not from me. I just don't have the chips. But I'm sure someone else will step in and do that. I'll sell wholesale board/parts and they'll assemble with chips and sell complete.

I'll sell them wholesale, individual. Will set it up as time goes on.
