Memorize a simple password in your head 1234BitcoinEater, then memorize the hashing procedure, e.g. SHA256(HEXTOBIN()) then use it as your password.
If you have multiple passwords you could combine multiple one way hashing algorithms and add 1 to the end of your memorized password, then every time you need a new one simply add 1 to it and hash the same way to get a completely different password.
Here's another hare brained scheme for you guys to consider:
- Take out your camera and take a picture.
- Make a hundred billion copies of that picture and stick it everywhere. In USB sticks, DVDs, memory cards. Throw them around the house. Make sure a few tiny memory cards end up behind the sofa like loose change. Even wear one as an amulet around your neck.
- Use the sha256sum of the picture as your password. Very easy to do on *nix

- And if you need multiple passwords just append a number:
echo "1" | cat - my_not_so_secret_pic.png | sha256sum
