Now like any computer mod project I do have a worklog posted here so you might find any questions you need already answered here..
DIY Cathode Worlog
Step 1: Supplies and the first steps
- 3/4 inch Dowel
- Wood, I used 1x6
- Cathode and inverter
- CDs - preferably some economy ones with reflective layers on both sides.
- Acrylic tubing. Link here
- plexi glass
- PSU micro atx is preferable
below is the general prototype of what we're aiming for
First step is to cut your wood. You can cut this to any real length you want. I ended up making my box about 5.5 x 5.5 x 5.5 so make sure you cut all of your wood to fit which ever size you want. You will have three pieces the same because these will be the top and bottom of your base as well as the top piece of the lamp. Then you will have two pieces for the sides, and one piece for the back.
Step 2: Time for paint
Once you finish some quick cuts you'll be ready for the paint. I went with all black, but go crazy; lime green or orange would probably look sweet in my opinion.
Step 3: It starts coming together
Next take your PSU. I ended up de soldering most the wires because they weren't needed. You will need to keep two ground wires, one 12v and the green wire going to the motherboard connector.
I also lucked out a bit on the PSU Fan, half of it was rounded so I took my hole saw and make an 80mm hole to mount it on the bottom piece. Then I cut a quick hole for the plug to fit into.
Step 4: Mounting the plug
Step 5: Mount the psu
Step 6: The face plate
In the plexi we'll be mounting the power switch and drilling some holes for ventilation. First to cut the plexi I recommend the crack and score method. Simply drag a razor blade in a straight line across the plexi 5-10 times depending on how sharp your tool is. I recommend using a straight edge. Then bend the plexi and it will snap along the guides you just cut.
Next drill a hole to mount the switch. And some more holes for ventilation. Make sure you have clean cuts, I recommend using a drill press to keep the holes extremely evenly spaced, a hand drill might wander and look bad.
Finally, to wire the switch, take the green wire from the Motherboard Connector and a ground wire and wire them to your switch. Once this is done, you'll have finished your front panel.
Step 7: Cutting your seperators
Now it's time to cut your plexi tubing.
I found that the miter saw worked great for this. I cut my segments to Â½inch but use what feels right. I ended up cutting 15 the first time, then going back and cutting 2 more to fill the extra lengths.
They'll look pretty messy and may have some ridges on them. I just smoothed them down on a belt sander then used my fingernails to break off the left over melted edges. When I finished, I had one really nice clean set of tubing segments.
Step 8: And we're done
The light isn't bright enough to function as a normal lamp but it's pretty perfect as a bedside lamp or for decoration. I think it's a pretty cool use of old computer parts. Lol the PSU I used is a 120w PSU from an ancient eMachine computer, so don't be afraid to tear apart some ancient computers for this mod.
Now I admit I'm a bit tired so I feel like I probably missed some spots of this but I know I wrote enough for you to figure out the parts I missed but if you guys have any questions just let me know, I'd love a good discussion.
