Halloween is tomorrow! Do you want to bring a carved pumpkin to work, but aren’t allowed to burn candles in your cubicle? Do you want to carve a mini-pumpkin that’s simply too small for a candle?
Or are you just running late and need to make a procrastinator’s pumpkin?
If you said yes to any of these questions, we just might have the solution that you’re looking for. Here’s an easy way to make a tiny blinking-LED jack-o’-lantern.
The blinking LED circuit is borrowed from a Tirefly, a commonly available type of motion-sensitive light that attaches to the valve stem on the wheel of a bike or car. Our quick modification (less than five minutes and no soldering) defeats the motion sensor so that the LED can blink all day (or all night) for you. (For hardened geeks who want to solder something anyway, we’ll also show you how to mod the circuit to use a higher-capacity battery.)
