This is my take on Adam Savages “Attenuator” I also used ShapeForgeProps version as an example. Here’s my list of most of the things you would need to build it. There’s lots of ways to make this more accurate to thier builds but I had all these electronics and pieces in my basement and I wanted to see how quickly I could build it and didn’t want to have to order any parts to accomplish it. I did a quick down an dirty video of my build.
Project box
1.5mm polyester sheet
Equip chaser Chip
5mm LED yellow/gold breathing effect
10mm LED - Red
50K potentiometer and dial
470 OHM resistors (really should put these on all the little LEDs on the chip as I did and not the one that come with the board, as they will make the LED not as bright.
9volt battery snap
Two switches
Thick gauge wire and connector fitting of your choice to come out the top (I used an old Cat5 wires and cut the ends off)
Find a cap that you can cut a radioactive symbol into, or perhaps someone from the community will make a 3D printed file.
