This is another one using the battery to produce electro magnetic field to light 4 LEDs using one very weak battery. The interesting thing about electro magnetic it doesn't rely so much on current but the electro magnetic field itself as long as the receiver is within the range they will light up. Stronger magnetic field provide stronger and farther range of transmission


Voltage booster that boost 9 volt battery to a staggering 600 volts or so

The world of electronic engineering is very exciting and the progress of humanity will depends on the new development of every good thing in electronic and electrical
