Some photos

Well some photos :)

Insignia on 20W Philips tube

The two tubes placed in the wooden box, reflectors are made out a 100mm sewage PVC tube cuted in half and lined with some reflective foil.

and this the 'comptraction' as it is made out of some MDF

Well, with the 'comptraction" the boards 200 x 300 mm can be produced with 8/8 rules

Still, a timer has to be 'produced' (shoemaker has some holes in his shoes), but untill a sand clock is used to time the exposure

As, for today, that's enough, some software has to be debugged (PIC)
