Another autonomous blimp

Another autonomous blimp, this one clearly modeled closely on Blimpduino (right down to the same Lego parts for the vectoring servo--hey guys, how about a callout?) but using a PIC chip rather than Arduino's ATmega. Also a simple IR-based remote, rather than RC. Major DIY plus points--the Colorado State team who designed it built their own IR… Continue
