<DIV><BR></DIV>Hi CD930,<BR>Sure dont release the PCB, but you could give us
suggestions on improving the RONJA design to 100 Mbps.<BR>You could point us
in the right direction, like the modulation technique to use, coding
technique, or LED used ,or lasers, other pitfalls you encountered ?<BR>Would
you like to support a "free" cause ?<BR><BR>Regards,<BR>Deepak<BR><BR>

Martin<BR>><BR>> Nice demo Martin, is there some chance that
documentation, tips or<BR>> howtos be available about this project some
time in future? Any plans<BR>> for some kind of open hardware licence
like Ronja is, or it will be<BR>> yet another of those projects that
inherit Ronja's ideas/hw, show some<BR>> good<BR>> stuff and then go
into some factory for big bucks only :) ? No wonder<BR>> why Cl always
gets upset when ppl start asking about 100mbps or xtra<BR>> range
versions :)<BR>><BR>> cya<BR>> LePiaf<BR>><BR>><BR>>
