Remote controlled flip Bahtinov mask and lamp
by C.Y. Tan 2017
I made a flip mask and lamp for my FSQ106 so that when they are mounted on the telescope, they will balance each other out when mounted on the opposite side of the telescope.
The flip mask and lamp are designed as a master and slave pair. I have chosen the flip mask controller to be the master and the flip lamp controller to be the slave.
The mechanical design of the flip mask and lamp are mirror images of each other. The principal parts used in the design are as follows:
- A servo controller made by Pololu called the Maestro.
- A servo that rotates greater than 270 degrees: the Feetech FR5311M.
- A sprocket and chain system for connecting the servo to the mask and lamp.
- Interlock switches to indicate where the mask or lamp is
- A mechanical lever switch
- A Hall switch
- A lamp made from an electroluminescent panel with dimmer and power inverter.
- Filter sheets have been added so that the RGB components of the EL panel have nearly the same intensities.
A movie of how the flip mask and lamp in action can be found on youtube.
