This circuit was developed as an offshoot of The Rabbit Hole, our local hackerspace's pumpkin carving night. There was interest in using LED candles to illuminate the pumpkins. And we didn't think that the cheap little tea lights would put out enough light to illuminate a medium size pumpkin so this was born!

It can be used for pumpkins, or any other decoration in which a candle is desired. The PIC microcontroller will be pre-programmed as well.





Kit Parts:

• 1x LED Candle Simulator PCB
• 1x pre-programmed PIC12F508
• 1x 100uF capacitor
• 1x 0.1uF capacitor
• 5x 2N3904 transistors
• 5x 1k ohm resistors
• 3x Yellow LEDs 5mm
• 2x Red LEDs 5mm
• 5x 82 ohm resistor 5% 1/4W
• 1x 4xAA Battery holder
• 1x 8 pin dip socket
