7250Re: [tracker2] T2 tracker package
- Apr 23, 2009Sorry for answering messages out of order, my inbox is a bit of a mess!
I got through about 150 messages on the plane, but got 400 new ones
between the time I got on the plane and when I got home.
The first 4 beta units shipped already. I've got to get some new PCBs
made before I do any more, though. Those required way too much manual
assembly. I should have some more units ready in time for Dayton,
though. I hope. (If anyone knows where I can get 1/16" black Garolite
G10 cut to size, that'd save me some time - the standard sizes are too
small to be useful, or too big to fit into my CNC milling machine and
cutting them down is a pain.)
You might have already said, but I missed it - what made the GPS mic
attempt a failure?
