After I wrote my reply I looked closer at the schematic and saw the how
big your caps are. I also noticed that you are using an LS14. I used
much smaller caps, probably 0.1uF for the filter and 0.01uF or smaller
for the pumps.

An Atmel atTiny13 is $1.40 in an 8 pin dip package. These chips power up

Certainly cheaper over the net than physical transport. I did look at
flights and they were not cheap (~ 1400 to 1800) and will probably
increase by 20% or so by next year. :-(
Living in dry country I also looked at the temps and humidity. ...
pretty steady 25-30 degrees with 70 +/- 5%
Perhaps next FISL will be on June, one dry month on Porto Alegre.

FISL, since 3th edition, has always been broadcast trough the internet,
using theora ogg encoding (watch with VLC, mplayer, etc).

Regarding next FISL+EMC Fest, I want to say that is a quite big CNC
community here in Brazil and possibly is very interesting to them
participate of such meeting...
I'm owner of a discussion forum focused in building simple CNC machines, and
some of us are using EMC² in our machines, and I think

Thank you Andy Ayre for such a great article on getting EMC2 and RTAI

There are two drivers, one for the AX5214 and one for the Futurlec
PCI8255 card.
They are called hal_ax5214h and pci_8255, respectively.
The pci_8255 driver has been included with EMC2 since 2.2.0, the ax5214
driver has been there since before the 2.0.0 release.
For either card, you have to

ok, forgot my last message...I managed to get the rtapi module to load.
I finally found the right spot to add the mcmodel=kernel option and emc
gets past the rtapi loading.
Then 'motmod' module gave me trouble. It said the following symbols are
undefined: cos, sin, atan2, acos. I had to go back
