I've scanned my own lecture notes (most of them anyway) and put them here as PDF files. They cover most of the material since relativity (and a bit of that). For the beginning bits of relativity, see here.
Hopefully, you can read everything and decipher my crude drawings ... let me know if you have questions. If you're using them to fill in the gaps in your own notes or augmenting the text, it will probably be OK. If you're relying on them as a sole source ... not so much.
