While watching my favorite TV show, The Big Bang Theory, I started tracing around an aluminum holoprojector and doodled away until I came up with this...
Granted its not a final design, but sitting back with pencil and digital micrometer, it was a good start. I shared my idea with my friend, Fred, whose CNC machine has produced several great parts for my R2 lately. A few days later, he turned my scribbling into aluminum goodness!
The cut aways are for two micro servos. Once lined up, I marked where to drill and tap some mounting holes (4-40 thread)
The end cap has a 10-24 thread screw in it now, a spot for the servos to attach to and move about.
And here is the temporary setup using a Servo Tester to move the servos around, checking things out.
So far, its rather clunky. These micro servos are cheap knock-offs and aren't moving very smoothly, so some HiTech micro servos with more power and torque are going to be needed. I also need to come up with a better linkage than two twisted up paperclips! But...it is a start!
