Introduction: 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.

Very cute

Very nice. All you need now is a sensor that will turn it off when it hits wind...

Or the slightest change in air pressure...

So you put up a picture and video of a project you made from a book? Am I missing something? Where is the Instructable?

Gadre (author)soulrider2232011-07-01

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

This and other 34 projects are now available in a book, published by McGraw Hill International: TinyAVR Microcontroller Projects for the Evil Genius.

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.

could you please make an Instructable on how to make one

matroska (author)2009-03-17

Wow that's just a brilliant idea! A very nice DIY project! Will interest others too, as I strike a .. PCB match against a box and when it will light!

matroska (author)matroska2009-03-17

However, I think the Instructables community would like more info about this, and on how to do it.

redbird01 (author)2009-02-11

Ditto to what NoBonus said! And I would add that this is a very imaginative use of the technology. I haven't figured out any practical application for this yet; But I'm sure that there are some very clever people out there who will. Very cool!

NoBonus (author)2009-02-10

Really clever!
