Solar bug

I made this little solar bug because a friend told me about his battery powered 'disposable' toothbrush (Oral-B PULSAR). This brush is like a regular manual brush with a little vibration motor and one AA battery. As the brush was worn I removed the vibration motor out of the brush and build this little bug.
After removing the motor I varified the needed power with a laboratory power supply. And purchased a solar cell which support the necessary power. For the legs I took a old IC and cable sleeve for the tentacles.
