Lord of the Lights

thingiverse

A Little Sunday Afternoon Project For A Better World. I Spent My 2 Cents Reusing Old And Empty Cells To Produce One Light To Burn Them All . This Simple Flashlight Works With Multiple Cell Types, Including AAA, AA, And Coin Cells. Specs: The Power Source: * White LEDs Are The Best Choice Here, Working Efficiently At Up To 3V. * Multiple Cells Can Be Used, Such As AAA, AA, Or Coin Cells (Up To Two Cells In Total). Key Electronics Components: * 2 LEDs: The White Variety Will Produce Bright Lights While Drawing Maximum 3V Current From Each Cell. * Coils And Resistors Work Hand In Hand With The LEDs To Keep It Functional. * A Small 32k Ohm Resistor Serves As An Additional Load Control Element, Allowing Smooth Energy Distribution. Adding Even More Features: 9V Battery Support Can Be Easily Added By Simply Breaking Down That Wall Between Batteries and Electronics. Key Component Changes Are: * Using Two Coin Cells And Placing Them Close To The 2.5 x 2.5cm Space To Keep The Size Compact * Coin Cell Holder For CR2032 (optional) to hold your spare coin cell Don't Forget! Any of These Electronic Components Can Be Replaced With Similar Ones Based On Availability. Cheers To Chris.
