CNC Mill Ring Light

There is a warm and fuzzy feeling that accompanies using my mill to make something for my mill.  Not quite a self replicating machine, but it helps make itself better.  I finally figured a ring light design I like.

I have made a number of different test parts and played with a few different LEDs before I settled on some LED dome light replacements.  They are from amazon.  They have 4 surface mount LEDs with a resistor built in, and are supplied with 12V.  The metal cones are meant to go into a car’s dome light receptacle.  I removed the cones with a soldering iron to leave a flat solder pads.

It goes right above the bit area, and two screws coming in from either end help hold it in place.  I gathered the red and black wires to a single connector each.  They connect to a set of wires that run up to the 12V that powers the under-mill lighting I installed a while back.

I could fit more lights in if I wanted, but the 4 “bulbs” look great.  Very bright and easy to see what is going on.  The camera made it look a little blinding, but it is not.
