Here's this weekend project.
I really don't know much about Servos, But I'm good at figuring things out that move.
I only have 1 Pie Panel moving and I need 3 more servos and linkage to get the other panels moving. Once I get all 4 Pies moving, I will have to make a decision on how to control all four.
Not being limited now with channels, But being limited by the Vex micro only having 6 usable servo ports. I may buy the Servo recorder from Servo City. This will allow me to use 1 channel on the Ebay 12 ch. remote. But the recorder will do the same movement of the pies each time I activate the recorder. More/Less, I can set the recorder to open pies 1-4, Then have it open 1 and 2, Then 3 and 4. This will give me a animation that will happen every time.
