I enjoyed both of those, and wonder what you plan for future episodes?
I'm asking because there is no shortage of Arduino material around the webz. In fact it sometimes seems there's too much, some of it subtly different from others, some of it conflicting and some of it factually incorrect.
Apart from some factual faults like suggesting to power servos from the Arduino 5V, the examples on this site are as good a place as any to start. What's going to make your series different from the others?
