I am also trying to learn kanji (along with a language course in college, but I'm on break now). I use this website, but mostly because I'm totally lazy and like flashcards that I don't have to make myself:
Drill and learn the Japanese kanji, learn Japanese
I don't think anyone's already posted this one, but if it has been, just ignore me. I like this site because it splits the kanji into the grades, which is not overwhelming at all (some websites and dictionaries just through them all together, which is scary). Good luck with memorizing these! I'm doing pretty well so far, which means that it's not impossible (but then again, I'm not giving myself a time limit because I'd just procrastinate >.<).
