Therefore I have been thinking of employing a new system where I have a screen displaying the same notes (in pdf), that I can write on with a 'stylus' pen such that the file and the writing is projected from the overhead onto the white screen.
Secondly, and far more importantly, I like to edit and update my notes from year to year so I need new acetate sheets every year. Firstly cleaning the ink off is messy and cannot be done after about a month. The obvious solution would be to reuse the sheets but there are a number of problems with this. perhaps of the order of 1000 per year which must cost in the hundreds rather than the tens. While I am happy enough with this I am not very happy with the amount of acetate sheets that I am using. As it stands all of my lectures are presented by me writing on pre-printed acetate sheets (printed with my notes with gaps for pictures, examples, etc.) which are then projected onto a screen using the acetate projector.
