I was contemplating the LED Projector today. My thoughts from about a year ago was to have some sort of way of projecting LED lights onto a wall or the ground for the purpose of having a Christmas display. Originally, I was thinking that I could project a series of LED light strings onto a polished cone. If I were to do that, you could be in a car and pass by the display and see some sort of display in the cone itself. There would be a radial layout of LED strings on the ground that would light up some sort of scene that would be projected onto the cone and then into the eyes of individuals looking at the cone. That is a little tricky because of the geometry involved and whether the eye level is in a car, or from someone who is passing on the street (a little higher).
My next thought on the project was to have some sort of hexagonal mirror that could be rotated at a certain speed. By having a linear string of RGB LEDs you would be able to paint out a scene onto a wall by flashing the LEDs on and off at a specific rate. There are hexagonal mirrors that are available in laser printers. I have two old laser printers that could provide these mirrors but I would need to figure out how to control them via a Raspberry Pi or Arduino.
This is a blog mostly about techie things, what I am doing to my apartment network on the cheap, IOT, 3D Printing, Raspberry Pis, Arduinos, ESP32, ESP8266, Home Automation, Personal Weather Stations, Things That Go Bump in the Night, and some side issues that need discussing. Remember, sometimes the journey to an end is as much fun as the goal achieved!

Thinking to get back into the LED Cube Project
Now that I have more time to myself, I was thinking of getting back into the LED Cube Project. I was also thinking of adding a reflective LED projector to the experiment in order to have something that I can use later during the Halloween and Christmas seasons. The controls are about the same except that the LED projector would have moving mirrors to reflect an LED strip onto a wall (for instance). The reflection could also be done to a Conical shaped mirror for use on the lawn.
I have also purchased an additional breadboard to get some of the previous ideas prototyped up and working. Remember, at last juncture I was unable to get enough control lines due to the chip that I was using running out of address space.
