I adapted a motorized light I bought from Jaycar for $40 and took the light out and mounted a Canon HV10. Useful for setting up shots where a camera man can't go for example Hard to reach places like high up on roof, tight constricted spaces, out of sight eg hiding on stage. This is the cheap alternative to a expensive rig.
Looking into building a motorized dolly next that can be mounted on the roof and camera travels up and down, using remote control car parts and metal rails. And here it is: facebook.com/Funnelwebspiderdolly
Let me know what you think.
