[hpsdr] Enclosure/Form Factor, was Re: Call for Project Leaders

[Ben Hall]

Hi Eric and gang,

Thanks for the reply.  I listened to the presentation earlier this 
afternoon and have been thinking about an enclosure since I wrote my 
message below.

I'd really like it if you could fill me in on the form factor 
discussions.  I'm very intrigued by the choices made - its a form factor 
I immediately recognized from the modular data acquisition systems we 
use at work by VXI Technologies.  (I work for the Army testing 
turboshaft jet engines and aircraft components.)  You buy a chassis with 
a backplane, power supply, and thermal management, and you plug in cards 
as needed for the data you wish to collect and the controls you wish to 
have.  It's an immensely flexible form factor.

I am going to put a a preliminary proposal together for an enclosure 
over the next few weeks.  I've got some work I need to do before I'm 
ready to propose it to the group:

1)  Understand the current form factor.  IE:  How big are the current 
cards?  Power supply?  (I never knew there were such tiny little power 
supplies on cards.  Neat-o!)

2)  Poll the community for future form factor growth paths.  Not just 
size, but heat, etc...

3)  See if there is an off-the-shelf solution.  I doubt it.

4)  See if we can modify something.  IE:  Can we take a standard Ten-Tec 
case, and with a few mods, use it?

5)  If 3 and 4 fail, start from scratch.

Once I get the above at least somewhat complete, I'll put it out for 
review.  Being such a newbie here, I'm *sure* it's going to be riddled 
with errors.

thanks and 73,
ben, KD5BYB
