We dont know if there is a video like this, but we show you how to make a lightbulb that lights up when the base is touched by human skin. The circuit has a transistor that amplifies the electricity that is transfered through the human skin. You will be able to illuminate a room by merly holding the bulb in your hand. A geeky way to light up an area, like in the olden times with a candle :P 
Is there a video link somewhere?
Hello! I have a question for you. Why those resistors are needed? I tried the circuit without any resistors and the led was brighter. So i just want to understand this thing because i'm a padawan in electronics :).
Minor Upgrades.<br /> <br /> Solder the circuit board wires to the original solder points of the light bulb base.<br /> Makes the mod &quot;undetectable&quot;<br /> <br /> Refrost the bulb interior(thinned white paint works OK, other methods might be better). This helps retain the illusion better(the audience only sees the light thrown, not the led inside).<br /> <br /> Sidenote,<br /> &nbsp;&nbsp; If you &quot;upgrade&quot; the hack, DON'T store it with the normal light bulbs!!!<br /> &nbsp;&nbsp; If someone that canot tell screws this into a mains receptacle... POW!<br /> &nbsp;&nbsp; That destruction can be fun in it's own right, but let's the &quot;magic smoke&quot; out, and the trick won't work anymore.<br />
Thanx We tried the resoldering of the bulb but failed we couldnt get our solder to stick.<br /> <br /> And ont he Refrost we need to try that too. Thank you for the advice.
Resoldering... tricky. It was probably a solder mis-match(lead solder on the bulb, lead-free on your iron?&nbsp; I've done this once or twice, mainly, I&nbsp;just fluxed the wire and solder, and re-melted the blob already on there. no need to add any more.<br /> <br /> Keep up the good work, and post some after-images, if you get the frosting to work ;-)<br />
