[Sussex] data aquisition

Fri Mar 25 01:57:12 UTC 2005

THANKS  Brendan : following the linux route my primary goal /dream was is to 
come up with a live "giveawayable" "cutdown"  distro for this purpose after 
much searching i found one similar to my imaginings! ...  some lads have 
been working on one for ecg (heart) monitoring it has a real time  extension 
and was said to be adaptable for other real time aquisition ect too good to 
be true ! as youll see from my other post "ubuntu boot prob" my tirelessly 
downoaded  test copy will only boot so far (mabey chipset incompatibility) 
and freeze .
I had realtime suggested to me by nik i beleive, from the slug , at the 
charmingdean show/fair which confirmed my thinking /stumbling along with 
some other good advice .
I suppose my aim is to have something that can control relativeley cheap 
hardware for as many engine types as possible primarily my aim is to get a 
project going for anybody interested , or a member of  a group of which i am 
a commitee member
tha GTBA "gas turbine builders association" these micro turbines jets / have 
been developed to a great level of technical exellence in a group with with 
similar ideals to linux user groups even helping manufacturers and writing 
the british and american safety rulings guides (bmfa amfa) for model flyers 
along the way for ten years now, whilst there are simple ways to run the 
engines including some comercial controllers .we dont yet have a viable 
/developable design for the association
 /linux community,
and as project theres going to lots of enthusiasm i hope .with some flashy 
graphical interfaces im sure !
p.s  i could  organise a run/demo& talk for the group at some stage if 
interest is there....
if i can get some momentum behind things it will be great ,but over night is 
not my expectation
i do realise the group is for primarily for linux !
thanks for your help i will throw some General  engine ideas questions at 
you Brendon along the way if thats ok ?
back after easter
