PCEU
2008-01-29 by Marko Pavlin
Hi! Here are some photos of my PC Exposure Unit (PCEU)... I made very simple exposure unit with VTF bulb: http://www.feltna.com/hardware/images/stories/exposure/IMG_8080.JPG I just "canibalised" old PC housing and divided with sheet of metal. Top side chamber has bulb inside: http://www.feltna.com/hardware/images/stories/exposure/IMG_8083.JPG made a slit into one side of the housing. It works as a "shutter": http://www.feltna.com/hardware/images/stories/exposure/IMG_8084.JPG when removed, UV light can pass to the exposed PCB: http://www.feltna.com/hardware/images/stories/exposure/IMG_8086.JPG Side door should be closed after placing the PCB inside: http://www.feltna.com/hardware/images/stories/exposure/IMG_8082.JPG and because the bulb is curtained, there is no danger for the eyes. and finally, it takes small floor area on the table. Components used: - old PC housing - VTF bulb, drilled, with UV filter sanded off, washed - ballast - installation material (cable, fuse, switch from the PC housing, bulb holder...) - couple of hen house hinges Regards, Marko
