Used for 9 months. Includes all the modular cables. I'm hoping to get 225$ for it but any good offer will be accepted.

Is the on-site market still part of the plan?

Reading this.

Hi,

My ubuntu mining rig (2x6970; 1x 5830; 1x 6870) running pheonix on bitcoins.lc is crashing one or twice a week (I reboot and restart when it happens)...it's stable enough that I didn't do anything about it so far but it's getting irritating in the long run. Warmest card is at 79ºC (6970), coolest (5830) at 60ºC. When it crashes the screen simply goes black.

What would be the right way to debug this? Is there a way to log what happens or my only hope is to tweak my pheonix settings?

Thanks,
vx

This might be a late/useless input but wouldn't it be nice to have the name (or model) of the board represent the FPGA that is on it (instead of generic name like X5000, etc.).

e.g.: XS6-150 (single FPGA) or 2XS6-150 (dual FPGA).

That will be easier to identify what board does what since the generic names does not carry any useful information.

Unfortunately, shapeways.com does not offer Tungsten at the moment. But there is silver, stainless steel, alumide, glass and a bunch of plastics.

Hi,

I made a physical bitcoin design and it's now available to purchase on shapeways.

Default material is steel gold plated but if you want to get it cheaper, there're plenty of other materials to choose from (like plastic).

The coin is 26.5mm x 26.5mm x 4mm. Shipping is free on shapeways.

Hi,

I solved the problems of backorder, escrow, payment, etc.: buy solid physical gold plated bitcoin from shapeways: http://www.shapeways.com/model/316756/physical_bitcoin__btc_.html?gid=mg

I'm sure people will want to buy more than one board...so some daisy-chaining mecanism would be good for your business

Hi,

If you use many board, can they be daisy chained or each board need a USB cable? If you're using JTAG, Xilinx devices can easily be daisy chained (1.TDO-->2.TDI-->2.TDO-->3.TDI-->etc.-->1.TDI)

According to this tutorial, it looks easy stuff: http://www.fpga4fun.com/10BASE-T2.html

I have the same problem...didn't find a solution.

Newbie question: how do you unsubscribe from a topic (i.e.: this one) to avoid seeing new replies in the "show new replies to your posts" page.

Hi,

What is the end target of your project?

1) Mine on FPGA's (meaning you think you can actually think of a way to optimize the design to a point where it becomes efficient)?
2) This will be a prototype for a ASIC implementation
3) It's just for fun

22$/MHash/s right now (165 MHash/s on a 3777$ chip)...not competitive but you gotta start somewhere (just being able to make something that works from scratch is impressive, good job). I think it does not matter as long as you have a plan in mind to make it efficient enough.

I have a similar problem...if I change cards count (go from 2 to 3 let say), ubuntu does not boot anymore...I need to reinstall OS. That's really tedious...there's gotta be a quick fix.

Just did.


The sheet is made to fit on a 19" rack (on a "table" fixture) but I admit it is cheaper if the unit can stack naturally...however you cannot beat this design in term of air flow.


Kill-a-watt was always showing the same thing (about 500W) so it was getting boring...found another purpose
