Well, today was a great day for this project :) I was able to get the lenses and hoods mounted, and the entire circuit mounted on a temporary base for testing. It all works! One change is that I will make the base “box” as a light controller only for now. I am afraid that I won’t be able to complete it by his birthday (a week away from delivery). So what I plan on doing is making a box for the base that has the light control circuit in it. And then I can make a ̶...

One is a 555 timer chip that will create a pulse at an interval determined by adjusting a potentiometer (from about 2 a second all the way to about 4 or 5 seconds). This pulse is sent to a 4017 decade counter chip that will cycle outputs after each pulse received. So it basically counts fro...

But….. finally I have the basic light circuit wired and working, and tested with the actual lights that will be mounted in when it’s complete. Now I’m waiting for the paint to dry, and assembly of the “lamp” portion tomorrow. I’ll post as soon as I can get it together, and post a video as soon as I...
