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.

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).
