I am working on an idea with using small copper tubes protruding slightly with fiber optic wire slightly protruding from the tubes. There is a small controller in the guantlet with a battery pack. I didn’t incorporate it into my build but I plan on using it for my next one.
Here’s what I’m setting up so far...metal tubes with 1.0mm opening for 1.0mm fiber optic. Nothing is glued down yet, so the placement you see is not the final product.
The rig I have is the correct sequencing for the whistling bird power up, so the rows of lights will go on in a 1,2,3 sequence just like the show.
I’ll post more pics when I nail everything down and all the fiber optics set.
As a general rule of them, you should always use some current-limiting device, such as resistor, when powering an LED. Some LEDs have the resistor built into their assembly. Others do not, so just be aware of what you’re buying.
LED Series Resistor Calculator for best brightness, you gotta pick and wire up your own resistor. You can find the forward voltage and current on the LED datasheet. Target how bright you want the LED within the datasheet’s specification.
