Can you share some more information with us? Hashing speed, watt usage, estimated price, drivers etc? It would be nice, if it will turn into a "product" which is able to sell. But really nice work anyway.

I assume Hashing speed and watt usage will be very similar to ztex 1.15y since its the same IC. Very small variations between different implementations of LX150

Would be very interested to know hashrate/price/power of the 28nm version. I suspect it would work a lot better than current generation ASICs.

Check the production files, and found some more photos of the project here we go! Seems more than impressive - the files, not the pictures

Same link won't work for me either Sad

I guess the link should be fixed by enclosing it in [ url ] ... [ /url ] tags, the forum software doesn't seem to deal with anchors correctly.

This is an open source quad spartan-6 LX150 board designed by The Seven and myself in collaboration.

Since it was completed way behind schedule we didn't see much point in releasing this version.
However some people kept asking for open source boards recently so we figured why not.

Version 1.0 has been manufactured and tested, but rev 2.1 has not. The differences are however minor.
The software is not very complete nor user friendly at the moment but The Seven has been mining with this board for a while now.
The plan is to make a 28nm version of the P7 platform where the software will include support for the LX150 version as well.

We will try to give as much support as possible through this forum and IRC, but the files are delivered as
is with no warranty of any kind. Use at your own risk.

So what happened to the diff clock driver, did you ever get it to work as expected?

Yes, it's not a perfect square but it works nicely.
I've tested many different drive strengths and termination resistors which didn't have much effect on overclocking.
There seems to be a wide margin.

The included files are set to LVDS 2.5V for the synth, which is the recommended setting
For extreme overclockers you may get a little more speed using SSTL 3.3 as it's even more square and faster rise/fall time.
However with SSTL the signal swing is so large it's way out of spec and not recommended.

Download link doesn't work for me. MEGA demands I should downgrade to Firefox browser while I'm using SeaMonkey.
