A long time ago i saw in Hack a day a light for macro in a camera and I thought it can be a good idea to use a led ring with the dremel to light up the working area under it.
Step 1: Materials
-Nine smd LEDs
-An old mobile charger (4.5-5.5v)
-One 15ohm resistor
- Male and female plug (optional, you can connect the charger dirctly in the PCB)
-The PCB, you can download the PCB stencil.
