Led Ring to mini-mill Araripe

A ring of led to illuminate the tool on my milling machine.

I used 24 led. 8 parallel strips of 3 led in series with a 200ohm resistor. Powered by 12V. But you can change the array.

I use some strong magnets glued with super glue to hold the ring on top of the drill column.

Printed in abs. Would be better if where white.
