homemade EFIS system and EMI

Thank you everyone for the input, now I am looking for some
prioritization. I received the new power supply from www.mini-box.com
and it is substantially better than the previous version
(http://www.mini-box.com/s.nl/sc.8/ca...it.A/id.356/.f ) however
I still get some noise in the radios. The new version is too big to
fit in the previous enclosure so it is sitting slightly apart from the
MB on its own.

I have started to jot down what the system wants to do, pictures and
status at
http://69.229.202.54:8080 Under the 'Image' folder one can see the
plane, the EPIA in the nose and the prototype ADC board.

So now I have a case that has to heavily part for the ATX power lines
to come into it & a non cased DC power supply. I have attached ferrite
beads to the power lines coming in/out with little improvement.

It takes time for many of the steps so I am looking for what you folks
think would be the 'biggest bang for the buck', or the right priority
to proceed with. (IE, build a brand new case for everything, build a
seperate case for the PSU, don't build a case right away but do X,Y,Z,
etc..)

Thanks once again for the brains helping noodle this over.


Check out this machine, only +5vdc required, linux capable...

I'm sure there are many more similar...

All Right! Now that's what I call an embedded system. Actually I use
systems almost exactly the same as these in my line of work... Put Linux
on them too.

Looks to be a nice system to play around with. It has the possibility of
handling both the data interface and computations. The main problem I see
with this system is no windowing system ie KDE and I think that was part of
his need.

UJ,

Well, it doesn't come with a video card if that is what you meant,
however, that is a relatively simple matter to fix. PC104 video cards
are quite reasonably priced & even support 1/2 or 1/4 VGA standards.

It's a PC. He can install all the Linux junk he wants.

How much does one of these development systems cost?

So far I have spent
$180 MB
$ 80 Power supply
$80 512Mb DDR ram
$90 on two USB flash cards
$30 data aquisition board materials
$30 odds and ends.
~$490
When I bought the EPIA the TC model was not out yet. This is what I
would have purchased these days saving $80 and a lot of headache. I
might end up buying this anyway and selling the old one on ebay.

I bought one a couple of years ago for around $1k (+/- a couple hundred
bucks).

Arcom also sells some very reasonable development kits.
