May 23, 2021: Installation is Complete

I’ve completed the installation.  Proximity Sensor Mk 2 is functioning properly in the base of the 5 Slat Message Board.

The Sensor Head for the Mark 2 Proximity Sensor has been wired and mounted. May 15, 2021.

Note: 23 May 2021: This power panel configuration was not used in the final installation.  The hour meter was installed separately. 

Continuing with packaging the individual components so that the Proximity Sensor Mark 2 can be contained within an automaton, I’ve created the Master Power module.  This module contains the three-position toggle switch, a 3 amp circuit breaker, and the hour meter.  All in all, this packaged up very nicely.  I continue to appreciate my 3d printer.  When I need another of these I simply need to print the file.

The toggle is three-position: Up: the sensor is active.  Middle: the entire automaton is off. Down: the automaton is on (the sensors are bypassed).

This Master Power panel will be painted and then mounted to the rear of the automaton.  It will be connected to the other modules via wires with connectors.

I continue to work with the electronic components that make up Proximity Sensor Mark 2. I’m appreciating my 3d printer.  Pictured you see the front face (top image) and the components that have been dropped down into a holder (bottom image).

This sensor module will be painted and then mounted within the drive frame of an automaton, facing the audience.  When someone approaches the automaton will turn on and will continue to operate until the someone has gone.

This sensor module will be connected to the other modules using wires with connectors.  This will permit easy removal for troubleshooting when required.

As I was building Proximity Sensor Mark 1 I had trouble ‘holding’ the different electronic components. They say that when the student is ready the teacher appears.  That is what happened in this case.  I discovered the Proto PCB boards and ordered an assortment.  They turn out to be just what the doctor ordered.  I can securely fasten components and can solder to those components very easily. Pictured (from your left to your right) you see the Ultrasonic sensor, the PIR (Passive Infra-Red) sensor, and the LED indicating lights that I plan to use.
