Hi!
About two years ago I've made a work area lighting for my Dremel Workstation 220. Really simple - 3AA batteries, resistor and a bunch of white LEDs (all in parallel) from broken flashlight. Not bad, but these LEDs have narrow light spots and large power consumption.
So I decided to make new work area lighting using Joule thief and some 120° white SMD LED's. BTW I've found a box with semi-depleted AA batteries.
Schematic:
Inductor core from old motherboard. Outer diameter ~14-16mm, green-blue. Seems to be powder iron.
Assembly:
 |
| PCB? Are you kidding? =) |
Light module
 |
| 5x ARL-1210UWC LED's in series |
 |
| Semi-transparent cover (also acts as case) |
Power section
 |
| Battery holder |
 |
| A lot of glue =) |
Final testing. These batteries (~1V each) are from remote controls. Light works fine, remote controls not =)
 |
| It works! |
Mounting light module to caret
 |
| Light will be here |

| Light module fixed with glue |
Ready to work! Room lights are off.

| Ready to work |
 |
| Much better! |
