    Default My green 250mW in PC case

    Hi guys and gals!
    A couple of weeks ago I've completed the first version on my green projector in old PC case. I decided to redesign the PSU to get +5, +12, -24, +24 volts from standard PC PSU. My version is not stable enough still so I have to use 2 PSUs. And there is enough free space for future upgrades (more green or RGB sweet dreams...)
    And some words on finishing (for David ):
    Step 1 - sanding. I used 240-grit sandpaper for steel lid and 400-grit sandpaper for plastic. Pumice powder and steel-wool are also good choice especially for figure surfaces. I've sanded with water sprinkled on the surface. And if you have big or deep scratches you have to use putty before sand.
    Step 2 - cleaning. I used common detergent powder.
    Step 3 - sealing. I used grey primer for cars (use white primer for bright paints (not pants )): 3 coats, about 15 minutes between each sealing session. The sealed detail should be smooth and even.
    Step 4 - drying. Leave sealed detail for 24 hours for drying (high temperature and low humidity speed up the process). The primer film have to be firm after this stage.
    Step 5 - painting. Paint several thin coats (don't try to do everything at one time, it's better to paint several thin than one thick coat), begin with hard places (edges, concaves, e.t.c.) and end with big plain surfaces. If you observe defects (particles, scratches) - let the fresh coat dry, lightly sand the defect and the next coat will hide the defect.
    Step 6 - final drying. I don't like this stage: the item looks brand new but you don't have to touch it. Just leave it for about 24 hours...
    Step 7 - polishing (if you like to obtain mirror-like surface). You can use burnishing pastes or car polishes.
    P.S. Sorry, technology pictures are from another project.
    Igor.

    Oh no, there was old Pentium processor (120 MHz) inside the case. The display makes me feel nostalgia

    I haven't decided yet, but it has to be something more powerful

    Mark, you are almost right , I planned to make big green fluorescent biohazard sign on top. But then I was disappointed with "fluorescent power" of green paint. Pure white shines much brighter under UV light.

    Josh, thank you personally for so high appraisal!

    Very nice job Igor! That's the best PC case build I've ever seen. How are those LW-50K scanners working for you?
    Thanks!

    Hi Adam!

    I'm glad you like the case too!
    Scanners are great, I'm pretty happy with their work. I was worry about heatsinks at first, but the exploitation has shown that heatsinks are moderately warm at large scanning degrees. In a word, the scanners and drivers are perfect for me.

    Cheers!
    Igor.
