Fire-free LED Matchstick




I just completed a new project: a fire-free and fire-safe LED matchstick. To light this matchstick you strike it against a normal matchbox filled with neodymium magnets. The LED matchstick has an inductive sensor that detects the magnetic field as you strike the matchstick against the matchbox and it lights up a LED in a flickering fashion. The power to the matchstick is through a 3F/2.7V supercapacitor and a DC-DC converter. As the LED lights up, the supercapacitor discharges and eventually the matchstick splutters off just like a normal matchstick.

The matchstick is controlled by a Tiny13 microcontroller. Still need to put it in a perspex tube so that its easy to handle and is not damaged.

    I wrote that book long after I put up the Instructable video. The book was published recently.

    Guys that was simple. He had a micro controller mounted with a super capacitor as its power source and then had a reed swich and an led. a reed switch is basically a swich that is closed unless a magnet is placed next to it.
