Another Blinky Project from Mr. Blinky

Laser Cut Pyramid Light Made from 1/8" Baltic birch This was a real pain to make so I don't think I will ever make another one of these. It turned out great, however, as it is delicate and beautiful at the same time. There is a large opening in the bottom for a light source of some kind. This could be a small wattage light bulb or a blinky engine. Which do you think I would utilize? Since the Pyramid Light just sets over the light source the source can be changed at anytime.

The Blinky Engine I wanted to make a light source that would illuminate the Pyramid Light in interesting ways. Four components are used. An ESP32 micro controller, a PIR motion sensor, a 4 NeoPixel strip and a push button switch. The Blinky Engine is powered by a USB charger through a USB cable. The circuit is built on a round circle of Baltic birch that was cut from the bottom of the light itself. I wrote code using the Arduino IDE to make this work. The engine has 12 distinct patterns meant to make the light streaming through the Pyramid Light vivid and interesting. At night the Pyramid Light displays beautiful colors and projects interesting patterns on the wall behind it. The Blinky Engine has two modes of operation. The first being that the light comes on whenever motion is detected. A display pattern is picked at random and the pattern is displayed for a short time before the light switches off. The second mode of operation is identical to the first except the light comes on periodically and automatically in addition to when motion is detected. The mode is changed by pressing the push button switch while the power to the Blink Engine is cycled. If mode 1 was selected and you do this, you transition to mode 2 and vise versa. The Pyramid Light is currently operating in mode 2 to help cheer things up during the dreary days of winter.
