Ultrasonic Batgoggles

Step 3 Cut ears

I trimmed the cut-off pieces of the cone with the Dremel, so that they were smaller and hot glued them to the inside of the larger cone pieces. They did not fit exactly but after holding them in place by hand the hot glue held it in place quite well. If you leave yourself enough space under the ears, you could easily embed the electronics inside the ear, one ear for the controller, and one for the battery. Unfortunately, I did not leave enough space and had to use an external enclosure.

Please take care not to burn yourself while using a hot glue gun!!! You can also easily melt the plastic cones by accident.
