Trying to make a wireless power transfer circuit following a tutorial from Youtube. It is not working and I need help.
We were task to design a PCB for a Wireless Power Transfer (WPF) to power a DC motor wirelessly. I found a YouTube tutorial that talks about wireless charging in smartphone [Website](https://electronoobs.com/eng\_circuitos\_tut58.php). I thought that it would apply here, so I followed their instruction and prototyped a circuit. Well it didn't work, and I need help diagnosing this.
Some notes:
- I used a 5v power supply, 9v battery, and 12v adapter and jack for testing. That's the only thing I had at hand.
- I used a 7805 instead of the AMS1117 from the tutorial for voltage regulation.
- I rolled my coiled flatly, which differs from the tutorial.
- I used a 5.1k resistor instead of 5k. I just used what I had on hand.
