Starting a new project for work

There is an ancient sensor system at work that detects if a golf ball goes through a certain hole and is connected to a doorbell.  This past winter the system get wet and died.  I am working on designing a system that will replace the existing one with one that has a more useful feature set.

The current feature set includes:

  • optical sensing (old physical switches get bent by the balls and stop working)
  • motion sensor (detect people crawling into the area to cheat)
  • local alarm for cheaters
  • local announcement of winner
  • remote display of winners
  • remote display of cheating
  • wireless to allow remote display to be moved as needed.
  • expandable wireless network to allow future addition of other nodes to enhance appearance of courses.

I am working on the prototypes of the sensor node and the display node.  I recently received two Adafruit Feather 32u4 RFM95 LoRa Radios and am working on code to use to test the range with the buildings involved.  I want to set up code that does not require a computer connected or a complex display to indicate a good connection.  I am currently using the RadioHead Library for Arduino to control the radios.


I recently built an infinity mirror. This is a prototype for a much larger mirror that I will be building for a local business that is opening later this year.  This one is running on an Arduino Uno and using FastLED to provide the control signaling for the LEDs.

Future photography posts on Business Website

Due to changes in web hosting future posts about photography will be at our main photography business site A Moment of Time Photography.  Thank you for following my photography projects here and I look forward to your comments at the new blog.

I will post more about my art and electronics projects here and will eventually rename this blog.  I just need to remember to document projects better to share with those that are interested.
