LED Campfire for Christmas crib lighting

prusaprinters

<p>I'm about to refurbish old grandfathers christmas crib and thought it might be a good idea to replace the old edison-like lightbubs for lighting the fire with some modern flickering LEDs.</p> <p>I salvaged a total of 16 cheap LED tea candles, each of them has a flickering LED without the need of additional electronics, running at 3V. Since I had a 12V DC adapter laying around I chained 4 of the LED's together. Having now 4 parallel sets of LED chains results in a cool irregular flickering fire effect, because each set flickers in it's own randomness.</p> <p>I know it is not the smartes electric circuit, but it works well for my purpose.</p> <p>I'm planning to cover the cone with some red transparent paper and stack toothpicks or small twigs around.</p> <p>Watch a short clip of the LEDs in action: <a href="https://www.youtube.com/watch?v=gjFDCiq9lYE">https://www.youtube.com/watch?v=gjFDCiq9lYE</a></p> <h3>Print instructions</h3><p>Category: Electronics</p>
