As some of you might know I am working on Super OSD, a fully graphical on screen display, which is based on my open source software and hardware designs (http://code.google.com/p/super-osd/)Basically I am working on two versions:* a datalogging FPV version for first person view (FPV) flyers; this has analog inputs, GPS inputs, sensors galore, and SD card datalogging. This would be a bit more expensive but probably no more than $70.* a basic version for connecting to an Arduino via. a two wire I2C bus. This would be very low cost (probably around $20-$25.)I am going to have to make PCBs of these, but how? Does anyone have any idea how I could get PCBs of these manufactured? I was thinking of places like ChinaPCB but they have an expensive tooling cost, so does anyone know any better places? Where are boards like ArduPilot, etc. made?
