Last night I wrote a little script to show that my beamer is the perfect clock projector.
You can display 2 numbers on an 8x8 led matrix.
Here is a little demo video. The height of the projected numbers were +-50cm and they are very good readable

I used this 8x8 led matrix, because the leds are flat with a diffuser and well separated.
If you use normal Led's, they have already a lens, and together with the optic of the "Sprida" lamp you will not be able to focus them and all the led dots are overlapping.
