We're trying to make our own system that doesn't end up being any larger than a competitor's system. Their system is housed in a metal box about 4"(W) x 2"(H) x 6.5"(L). They are using embedded Linux on an ARM processor with a DSP (SHARC ?) to handle the I/O. I was pointed at Advantech: http://www.advantech.com/products/Model.asp?Category_ID=1-D6LKE&bu= and have found similar PC/104 equipment at a few other vendors. Without doing much research (we usually build much larger VME based systems), there seems to be a lot of options in PC/104 modules. -- Dan Eischen ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I had one of the very early soekris boxes and found it to be a gem. If a 5x86 133MHz processor meets your needs, you'll like it a lot. I haven't tried the net4801 board, but I've worked with other Geode designs and if you need more cpu, that'll probably do. Good luck. -- "Where am I, and what am I doing in this handbasket?"

Yes, it looks nice. The form factor is just a bit larger than PC/104, especially with a PCCard plugged into its side. We'd also need some sort of general purpose I/O card which are fairly easy to find in PC/104 stacking modules. -- Dan Eischen ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Wireless Embedded monitoring
Anyone have any experience with PC/104 or other really small footprint platorms and FreeBSD? We need to build a small box for equipment monitoring (temperature, pressure diff., vibration, indication). Just a few discrete inputs/outputs, and analog inputs would be good enough. The hard part may be sampling an A/D signal at up to 30KHz, so having the I/O card do the sampling and buffer it would probably be necessary. The box would also need to have a supported wireless or a spare PCCard slot. Deployment would be in a shipyard in the Northeast, so being able to handle -30F to 100F would be necessary. Maintenance engineers would walk around on a daily or weekly basis and download sensor data from the monitors with a laptop (or some other handheld PC) for analysis (looking for equipment failures). Any ideas on hardware (SBC, I/O board)? -- Dan Eischen ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
