GRADE 12 STUDENT IN ABRA INVENTS WIRELESS POWER SOURCE
AN INCOMING Grade 12 student of Abra High School invented a device that can light an electric bulb using a wireless power transfer.
Jhentrix Castillo,17, used a Tesla coil and a laptop charger to run the power supply into a transformer to convert 30 volts from 24.
Using a TV flyback driver circuit, the device emits high voltage to drive two recycled plastic containers that he used as capacitors.
Castillo said that he honed his skills under the mentorship of his former 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 said.
Castillo, whose dream is to become an electrical engineer or a pilot, also invented a scooter powered by a grass cutter and a device that can convert distilled water into flammable gas using a steel plate.
