5V 2A
This project operates on the principle of electromagnetic induction to transfer electrical energy wirelessly through the air. A standard 5V 2A or 12V 2A power adaptor supplies direct current to the wireless power transmitter module, which converts it into a high-frequency alternating current. This alternating current is then driven through the transmitter coil, generating a fluctuating magnetic field around it. When a compatible receiver coil is brought into close proximity within this magnetic field, an alternating voltage is induced in the receiver coil via mutual induction. To make this power usable for standard electronics, the alternating output from the receiver must be converted back into stable direct current. This is achieved using a rectifier circuit composed of diodes and filtering components, which transforms the AC waveform into DC power suitable for lighting LED matrices, powering interactive media displays, or charging smartphones. To ensure optimal energy transfer and physical stability, custom 3D printed PowerTiles house the coils, while embedded magnets provide precise auto-alignment whenever a device or tile is placed against the power wall surface.

Frequently Asked Questions
No software or programming is listed or required for this setup, as it functions entirely through hardware-based power transfer.
You can use either a 5V 2A or a 12V 2A power adaptor, depending on the voltage requirements of your specific wireless power transmitter module and connected load.
The 3D printer is used to fabricate the structural PowerTiles that house the coils, while the magnets ensure the transmitter and receiver align perfectly for maximum power transfer efficiency.
