Use a large piece of heat shrink tubing to protect the circuit board. Repeat with the coil assembly that will go in the bag.

Use a pencil to mark your shelf where your bag sits.

Tape the coil and circuit board to the shelf.

Our bag has steel feet, we can use these to our advantage! Since inductive charging requires precise alignment, affix some magnets to the shelf where the steel feet of the bag rest.

Plug the AC adapter in to the wall.
