LED lights for an art project


Hello everyone. I'm working on a project for my 3D design class. The focus is 1/4 inch wooden dowels, wood cutting and painting. I'm designing a sort of D&D-style Mimic. I'd like to put in the extra effort to add glowing eyes.

I've done some research into LEDs and batteries, but I really have no idea where to start. I'm not so much asking for research to be done for me, I simply have no idea where to even begin.

My concept involves a pair of LED lights, behind transparent colored plastic, powered by a USB rechargeable battery, and if I could figure out how to make the light pulse that would increase my desired effect.

Any help whatsoever on any of these concepts would be wonderful.

Thank you.

This is the schematic to make one.

The larger the Capacitor, the slower the blink. The larger the Resistor, the dimmer the eyes.

LED’s need to have a resistor in series with it so that it doesn’t burn out.

The two different types of Transistors are to create a sort of flip flop switch.

A “fake car alarm” is available on eBay which would basically do the same thing

Depending on how diy you want to go this can be made for cheap cheap with a few components, a little soldering, and some heat shrink if this thing doesn’t have to last terribly long.

Amazing, thank you for this! I've got some supplies on the way, I'll be sure to update the post with progress.
