Wireless electricity experiment using a Tesla pancake coil and the Lasersaber SJR Looper circuit powered from grounded mains. In this electronics build, I convert the classic SJR Looper into a wireless power transmitter capable of lighting an LED without wires.
You’ll see the original and modified circuit diagrams, how the LEDs are removed, how the pancake coil is integrated, tuning with capacitors and potentiometer adjustments, and real-world testing of micro-watt level wireless energy transfer.
This is a practical experiment in:
• Wireless power transmission
• Tesla coil pancake coil output
• Joule thief style oscillators
• Grounded mains energy harvesting
• Ultra-low power electronics
A fascinating look at what tiny amounts of ambient mains energy can actually do.
Let me know in the comments how you’d tune or modify this further.
Chapters:
00:00 Project Overview & Channel Update
01:05 Finding the Old Tesla Pancake Coil
01:45 Can the SJR Looper Produce Wireless Power
02:44 Original Circuit Diagram Explained
03:45 Standard SJR Looper LED Demo
04:30 Removing LEDs for Coil Output
05:45 Integrating the Pancake Coil
06:40 Tuning with Potentiometer & Capacitors
07:40 Micro-Watt Wireless LED Test
07:55 Final Results – Wireless Output Achieved
