[App_rpt-users] Mini ITX board or Beagle board or ?? or ?? forremote repeater sites

[George Csahanin]

Shaun, her's how I've been doing it:

Parts from mini-box.com and logicsupply.com

Intel D945 GCLF board (a problem, not made any longer)
M200 case (non LCD)
Pico PSU80-WI (WI very important)
1GB ram
I run Limey-Linux off a 256MB CF card.

I replace the blowers on teh case with ones that have better bearings, the M200 stock fan WILL die after a short period.

I but NOS or used D945 boards on Ebay.

They just keep chugging along, no disk drive to wear out, and as long as you don't reboot no added read/write cycles on the CF card. 

For motherborads, I have been eying the Intel DH61DLB3. 

But I still have one more D945 on the shelf. 

I tried the Pico PSU80. Yes it works, however it drops out under about 11.8 volts input, AND the 12Volts pass along directly to the CPU regulator thru the 4 pin connector. Noise on the 12V, or too much 12V input (voltage swing on input supply above some point) will kill the motherboard. The -WI power supplies make the 12V as well as the 5V, much tougher to kill. Next to try is the M3-ATX supply, works on 6-24 volts input, much more forgiving.


In the future I want to try a Beagle but I have yet to see a "made for it" case, that would convert me...just when I got a handle on rolling my own Limey-Linux...

  OK, I admit. Have not spent too much time with Mr Google on this one, but here goes hoping for a short-cut answer................

  I would like to run each of my seven repeater sites (mains/grid powered with 12v standby bat) each with it's own URI and AllStar node. Some sites will have two URI's.

  Question; 
  What PC should I use at each site (12v PC would be nice, and with "auto power on" from dead battery when mains power returns)

  I had a look here http://www.mini-itx.com/ but the amount of choice is overwhelming. No idea which one is suitable.
  Then there is this thing called a Beagle Board??


  The processor must be fast enough to handle 2x URI's. I tried using a HP netbook and an Asus eeePC  but voice overs were a bit choppy as if the processor was battling.
  I do not really want fans, hard drives or any other antiquated moving devices (when are we going to see quiet, passive pc's at the workplace?)
  I do not need wireless, just an Ethernet port.
