If not for [Nikola Tesla], we’d be pretty behind when it comes to electricity. So to pay homage to one of the greatest inventors, [David Choi] decided to make his very own wireless Tesla Desk Lamp!
As expected, [David’s] a big fan of [Nikola], and has always been inspired by his life and experiments — in particular he loves wireless power. Ever since he saw a Tesla Coil light up a bulb from a distance he was smitten. He even named his cat Tesla.
The funny thing is, [David] actually failed physics in high school, but a few years later decided to pursue it as a career while attending Wesleyan University. It didn’t stop when he graduated, he also studied electronic design in his spare time — which is where he learned about resonance.
Wanting to apply what he had learned he has created a very unique wireless desk lamp. Don’t let the pictures fool you; it’s actually 3D printed! It uses one of those retro “vintage” light bulbs, which has it’s power transmitted to it wirelessly by a 6.5MHz signal. It was relatively easy to get the wireless part right, because once he had calculated the number of coils he needed, all he had to do was 3D model the track for the copper to go in.
