Re: Onboard computer?
 

As Mark said, we used a Zotac based system last year. Built in Atom dual-core chip and Nvidia graphics. RAM and SSD were added separately, each item well under $400. If you'd like the exact component list just send me a PM.

Due to weight and size issues, we opted to skip it this year. To do it right (prevent ESD, metal shavings, other damage), you really need to have a good enclosure for the machine, and even with a MicroITX system like this, it can take up valuable weight and room and we simply didn't have room.

We do have a raspberry pi that we've been playing with, and may use in the future. There is really a great selection of low-cost, powerful, and power-efficient ARM boards out there now, the Pi being the cheapest, but for a bit more money you can get something quite a bit more powerful and suitable for vision processing.
