Sounds cool, Brian.
I'm finishing a printrbot (assembled and wired. just need a cable extension for the extruder motor, so I can go to max height). Would love to show it off. Assuming it calibrates/works.
Also tempted to show off my near-complete "Phase Table" project (a DIY touch surface table, using NaturalPoint's optical tracking cameras. Just need to figure out how to program it's output as an HID driver input. so that it can pretend to be a proper windows7 multitouch input. need help finding a forum or community that understands this process. )
(and/or should just make a input DLL for a simple Unity3D game demo).
Pretty sure neither of these would be hands-on friendly for kids though.
But I'm planning to be down in San Fran the last week of March (26-30th) for the Game Developer's Conference.
So hopefully share these with yall next time. ? (i'll email Robin to check the dates).
Are there other Corvallis-tech meet ups where people share their hobby projects? besides the Beaver Bar Camp?
