11. May 2017 A better OMX Player Controller
omxplayeron the Raspberry Pi for video playback because it utilizes the Raspberry Pi’s hardware video decoding. Because the front-end is a separate application, I just need to remote control OMX Player to start and stop the video and figure out how far the video has played back already.

28. November 2013 Raspberry Pi Pulling the Plug
While browing for different breakout boards for the Rover I’ve discovered a nice little board that has a push button and logic pin to control a MOSFET.
This little contraption allows switching on and off the power, say through a USB cable.
Below is what I did to make the Raspberry Pi switch itself off completely on system shutdown.
26. November 2013 Using the Motor Controller
The Raspberry Pi has only a single PWM output. The Dagu Rover 5 chassis has 4 motors and 4 optical encoders that need reading as well. So my approach was to get a PWM servo/logic controller that could control the Dagu Motor Controller and additionally some servos for the camera pan/tilt.
