More Mindready, and Tri-M

Postby John Nagle » Tue Sep 20, 2005 7:32 pm

As we come up on the DARPA Grand Challenge, we're still
struggling with Mindready. We own three embedded computers;
the vehicle needs two to operate fully, although it can limp
along with one. The machines are from Tri-M, and are NOVA
Pentium 4 computers, supposedly "ruggedized" and priced
accordingly.

So far, every one of these machines has broken at least once.
We just got one back from repair (which requires shipping them to
Port Coquitlam, BC), and had to send another one out the same day.
They don't fail while being driven around; they just fail, for
no visible reason, usually at powerup. Failure usually
means the fans turn, but there's no VGA output and booting does
not take place. And they've come back from repair with
FireWire and serial ports broken.

We need a valid Mindready LLA license on only one machine.
The problem is getting a valid license and a working machine
together at the same time. We can't tell if the FireWire port
is working until we license the machine, and then it's too late
to transfer the license. We actually own four Mindready licenses;
two for development and two for the vehicle. I'm trying to
purchase another license, but can't get Mindready sales on the
phone. And they close in 90 minutes. Another day lost.

The total cost of ownership on this stuff is very high. Every
hardware failure means days of downtime, even if you have spares.

I presume this: http://www.tri-m.com/products/icp/nova8890.html

It sounds like you are using a supplied chassis w/power supply. It might not fit mechanically but try plugging in a standard PC power supply the next time one of the Novas stops working.

It's not the power supply. Tri-M is trying to figure out
what's failing.

The problem seems to be airflow related; the packaging
and fan positioning really don't match the motherboard
well.

Good to see atleast Tri-M are communicating with you.
