Lego LED Flashlight - Instructable
Lego-Man may have wanted a little excitement when he set out to construct the Lego LED flashlight, however, the gadget certainly seems to have been a productive exercise in the use of “discarded” Lego pieces. Additional items required for the Lego LED flashlight include:
• a 2x6 lego brick
• a 2x6 matching lego panel
• small flexible insulated wire
• electrical tape
• 1 superbright LED (white is nice, but you can get a color to match a brick)
• a switch (i used a small toggle switch from RadioShak)
• 3 LR1130 button cell batteries.
