I have a love for electronics and technology, and really enjoy building them. (or anything with moving parts/electric parts). On my family's birthdays and other occasions I like to make really simple electronic cards. Here's how to make them.
(maybe not any as complicated as the picture, because this has so many LEDs)
Thanks to these websites for pictures:
Step 1: Materials
I usually use the following:
-LEDs or a small motor
-I usually use nine volt batteries because I don't have the money for button cells, which work much better because of their size.
-The ability to not get frustrated and rip everything to pieces (I barely make this one)
