Heated Bed Warning Light

Hello everyone, I thought I'd share a circuit I am using on a little 3D printer upgrade project.

I have a heated bed PCB for my Printrbot that I am currently adding to the underside my aluminum bed. I needed clips to hold the pcb in place and provide a housing for wire strain relief. I designed some and printed them out. I wanted to add LED warning lights to the clips so they would glow when the bed was hot. I really wanted the lights to stay lit after the bed was off and slowly dim to nothing over about an hours time like the warning light on my stove does.

So far it's used to test modified Eddie firmware.
As I mentioned in an earlier blog, I was given a bunch of really cool robot parts by Parallax in exchange for modifying their "Eddie" code to work with different … Read more
