Spent a bit of time today making this light prototype out of some MDF I
CNC'd and some yellow LEDS (next revision will be white but I bought a
1000 cheap yellow LED's some years back so they get used first!). It was
quite a challenge to solder so I'll tweak the CAD to make the pocket a
bit larger to give me a bit more room to work in. I have a few ideas for
different sizes of these... Firstly the internal diameter of this one
matches the spindle currently on the
CNC so I hope to have a snazzy
spindle light that I'll probably attach with some small neomydium
magnets in the back of the case. Another size I'll make for the manual
mill spindle and I fancy making one that could fit to my
DIY helping hand accessory for use in combination with a lens. They also could make
a nice light to mount on a camera to take macro shots.

What voltage did you need for 8 LEDs? I was surprised by the white ones having a 3v drop.
I decided to run the LED's at 5v supply with a 3v forward voltage and worked out the resistors accordingly...I tend to run about 25ma to standard LED's but it's always slightly adjusted by whatever the closest resistor is!
