Light Probe – More Woodworking

Got into the shop and (crudely) built out the next part of the light arm.  I have a seemingly endless supply of scrap 3/4″ plywood laying around, so that’s what I used. Made the lower part of the rotating mechanism 10 cm square then rounded the corners for effect. The vertical part of the rotating mechanism is a simple 10cm by 12 cm. I recessed the servo just like last time. Finally, I attached a 1/2″ x 1/2″ piece of scrap basswood to the vertical axis servo.  Ugly as sin, but it works well enough.

Here you can see the unit disassembled into its two pieces. To assemble it I just slide the servo horn onto the shaft.

 

 

Here’s the unit assembled. the top portion spins on the X axis and the arm spins on the Y axis.  I’m going to attach the photo resistors to a mechanism at the end of the arm.

 

That’s it for now.
