An incoming Abra High School grade 12 student developed a device that uses wireless power transfer to light an electric bulb.
Jhentrix Castillo, 17, utilized a Tesla coil and a laptop charger to power a transformer that converted 24 volts to 30 volts.
The device creates high voltage using a TV flyback driver circuit to drive two recycled plastic containers that he utilized as capacitors.
Castillo stated that he refined his talents under the tutelage of his old electricity teacher, Joseph Garcia.
“He showed us how to calculate the winding current of a transformer to measure the exact flow of volts needed for our project. He taught us the fundamentals of house wiring installation that could land us a side job amid this pandemic. He taught me many things and for that, I will be forever grateful to him,” Castillo said.
He added that Garcia supported him and sustained his interest even when no one believed in his potential.
“When I was a child, I used to swipe my finger through a candle flame. Now, I can’t believe I can run my hands through this electrical current and be totally fine about it,” Castillo added.
Castillo, who aspires to be an electrical engineer or a pilot, has built a scooter driven by a lawn mower and a gadget that uses a steel plate to transform distilled water into flammable gas.
