Step 6: Holey Traffic Cone

I punched the holes with a soldering iron. The fan in the background of the first photo is to blow the fumes away. Burning latex can't be good for you, and it makes a lot of smoke. Set up outdoors and away from anything flammable like dry leaves or grass.

First, I divided it with eight vertical lines and five horizontal ones. I used a felt tip marker and just did it freehand. The felt tip washes off easily. In the bottom quadrant, I punched forty full holes; the second tier, twenty; the third, ten; the fourth, five; and the top one, three or so. I say full holes because I pushed the soldering iron all the way through -- I also made shallower holes by just pressing the tip in a little. It's cone-shaped, so you can make a variety of diameters. This pattern is just a suggestion -- you could do anything, constellations, subway maps, whatever.

After the holes are done, use a pocket knife or a putty knife to scrape the little burrs off both the outside and the inside. This part sucks, but it looks a lot better after because those burrs are black and block a surprising amount of light. Finally, run over the whole thing with some fine-grit sandpaper to take the last fuzzies off.

Other patterns are possible; I made an earlier version of this lamp by Photoshopping an image of cornstalk into a halftone pattern, printing it out, tiling it onto the cone, and drilling through it as a stencil. If you want to drill, you have to stuff the inside of the cone with newspaper or similar because otherwise there's no back pressure, and the cone just bends, no matter how sharp the drill.
You could shoot it with a shotgun and the holes would probably turn out very smooth, eliminating the fumes and the scraping with the pocket knife, and the black burned plastic.<br>Cool ible.
Talk about having flash backs&lt; i made one in 1977 with a cone the General Telephone man left behind, It was awsome because it said GENTEL from top to bottom. Made for a good party light in the 70's..thanks for the memories.
Hmmm... Where did you get a traffic cone? :P This is cool! Imma rate it 4!
You can get them in VLC programs.Not VNC.
I <3 VLC!!! lmao:P
they sell them at hardware stores
Lol, ok thanks!<br/><br/>But notice how I said &quot;Where did <em><strong>YOU</strong></em> get a traffic cone?&quot;<br/>
My friend and I found one while kayaking in a little lake over here.
Nice instructable.
If you put tape on the back side before you drill the holes.....it will stop the wood from splitting and chipping....then just peel off the tape! :D
Looks great, Nice work
really cool! Do you think light will travel trough ticker cones ?
Nice! I want to make a mini version of this.
make a mini one using leds =D<br/>that'd be cool, having it on your desk and all :p<br/>
Nice instructable, as a suggestion you may want to consider adding a materiasl/tools/ safety step. Nice job on your project.
Sweet man... so doing this! Man, after I've done all the crazy shizz I have in mind my room's gonna be crezzeh. Props and five stars.
Wow, an idea I've had but not posted, rated and featured, I'm impressed with this one, I never had the afterthought of elevating the cone. As a suggestion to get more light output switch to a CFL 'daylight bulb' they put out more light and in a wider spectrum, they travel through stuff like this really well.
