  • Wheres there other guy who make it ON and OFF? ^^

  • term led -_-"

  • lame

  • I know how to do that with a LDR thats for sure

  • wat the fuk

  • Nice.

  • I thik youtub ereally needs these funny old school videos :):):)

  • This circuit is started by voltage from a one of colors RGB diode,when you put close a strong light(match fire). This project is describet in Polish magazin called "Elektronika dla wszystkich".Sorry for my horible english...I still study;)

  • Magik, to ręce Piotra Góreckiego :-)

  • the trick is that the green things are not leds.they are eyes from the rare mammal whose scientific name is "sensus voltagus".

    the eyes generate the nerve impulse amplified by the position of the match stick and the air current caused by his hand coagulates the snowden dropularns near the larger maltiferant anti loponth.....possibly...??

  • shut silly...

  • I betting it is a circuit using capacitance sensing. basically he gets the match head near/on the LED and it turns on due to the change in the capacitance. it uses a on/off toggle setup and when he touches it again to "snuff it out" it again changes the capacitance of the circuit causing it to turn off. he could touch it to turn it on.I have made many circuits using this type of technology for everything from stealthed CD/DVD ROM drives to eject to the power on button for a PC.

  • No, LEDs actually put out voltage when exposed to light, like a solar cell, but much, much smaller current and lower voltage. You can use LEDs as crude sensors.

  • Tell me more please. :)

  • pls zoom all the circuit. i think the other hand is turn on & off at the same time

  • Ooooo very interesting, XD I want to make this circuit too XD

  • Thats good, where is the circuits and add more, more focus and clarity. It is a bit blurred.

  • There will be an explanation soon

  • please could u look at the circuit i made thanks

  • HOW YOU DO THAT??? Please let us know...

  • The circuit is specifically designed so that the led does not have enough voltage drop across it to light it up, but almost. When he uses the match, he just provides heat to the led, which increases its temperature, which increases its resistance, increasing the voltage drop on it, thus it lights up. Him putting his fingers over it has the opposite effect, it cools it down, so it turns off...

  • Man this is exciting.. im an Electronics Student currently havent seen anything with Temperaturce inductors like that.. but i would be really interested if you could givem an explanation about it.
