elements that I used :
- monitor by Compaq TFT5015 – contrast 300:1, 15” -1024x768, I’ve removed anti reflex layer
- fresnels 330 and 220
- lens **broken link removed**
- box made of waterproff plywood , 6mm thin
- ventilators – bigger one from xero, smallest from PC and Xbox360
- reflash from some old car lamp
- wires, cables, electric elements, grills, etc.
matrix consist ribbon that connect electrical elements. There wasn’t any problem with putting longer wires:
box:
fresnels and matrix grab in frame
first fresnel is screwed to frame, matrix holds by plastic grabs. Second fresnel lays on washer. 15mm from elements.

building phase
electrics and lamp. Small transormator powered xbox ventilator that is situated at top cover. It is plugged to lamp circuit. When lamp is on, fresh air goes between frames and cools the matrix. When lamp is off, ventilator doesn’t rotate. Only main ventilators are on- big one from lamp side and from lens side. Elements that can be on voltage, are secured by covering wires.
