LDR Cowling
This shows the gradual evolution of cowling solutions for the LDR. The presence of ambient light raises not only the zero level but also the break level between 0 and 1, so it’s been a headache to adjust the arduino … Continue reading
GIRC Robot Preliminary External Design
I’m still attempting to integrate the servo command sketch with the flash communication sketch, but I figure it’s time to start thinking about the external design of the robot. I plan to use a laser cutter on thin wood, with … Continue reading
