Test the wireless charging. The orange LED must be on when both coils are near together.

Remove the mounting.

Now your wireless vibrator is ready. If you like you can build a charging station.

Optional: Build a charging station.

Print out both parts.

Cut a USB cable. Plug the cable through the hole of form B.

Now connect the USB wires with the sender module. Solder the red wire to the (+) pad on the wireless charging sender. Solder the black wire to the (-) pad.

Glue the sender board on the bottom of the red form. Put some glue on the cable to fix it. We used hot glue.

Now glue the black form and the sender coil together. We used simple “UHU”-like glue. If the distance between coil and form is too large the charging could be rather slow. So don’t use too much glue.

Now put together both parts. Again we used a simple glue.

Insert the USB connector to your PC or any other source. Now the vibrator should be charged which is indicated by an orange LED.

Ready! Have fun with your collection of wireless DIY Arduino-compatible vibrators.
