I have no experience with inverters and I'm trying to help my daughter build one for her science fair. Do these look like they will work? If so, which one looks stable?

hi rtill

first of all carefully read that:
http://www.repairfaq.org/sam/samschem.htm#schsaf

IMMO, they are NOT safe electronic thing. A wrong move, and you/your daughter/anyone will be a death man/woman/animal.

first link: hi-frequency and hi voltage inverters for fluorescent lamps. They use a ferrite core transformer (not very simple to find and to wind)

second link: grid- frequency general-purpouse old-style inverter. It use a common transformer. It is not stable in frequency and voltage output (it depends on the load applied).
