Seashells and electronics - what to do with all those limpets except for to fit push-buttons, batteries, holders and motors and LEDs inside.
It took me a while to figure out the right term for these shells. They are limpets and not barnacles, as i originally thought they were >>http://evolution.berkeley.edu/evolibrary/article/analogy_01
I've always liked collecting seashells, and have always wanted to do something more with them than accumulate them in my parent's garden. So now I want to see how far I can go to integrate small electronic circuits inside them. Limpets are nice to work with because they are totally open on one side and the bigger ones even offer some depth.
The limpet buttons are very simple, they use a push-button to trigger LED light or a vibration motor. I decided to use a push-button rather than a switch so that they are only active when touched/pushed.
