When I was a kid I really wanted to become a Mad Scientist. Frankenstein (the patron saint of the Mad Scientist) had Electrical and Biological toys. So here is a shopping list for both. Visit the links and dream of the best la-bora-tory ever. I’m sure that ListVersers will have suggestions if something is missing - but don’t just tell us, please track down an on-line source and post the URL to the item (a page with a photo would be nice).

Mad Scientists like these switches because they are dramatic to flip and it is easy to see the connection. Not to mention all those exposed electrical circuits. The best ones are double pole, double throw. Cheap enough to get a bunch and mount them on the wall. These are mounted on a bakelite base. These are essential components when trying to build a living creature as they will make the connection between your corpse and your power source.
You can buy one here.
