Hello everyone! This instructable will walk you through some steps to create this (or similar) table lamp. The lamp's pattern comes from an electron microscope image of a leaf. Dark areas in the image translate to small circles, while lighter parts of the image generate progressively larger circles. The image is cut into four panels which make up the lamp itself.
The whole lamp costs about $25.00 if you have free access to a laser cutter. I am fortunate enough to have access to a laser, which I used to make this lamp. However, you can simulate the effect by using a hand drill or drill press.
The pattern is generated digitally, using a program called Grasshopper. I'll only discuss this briefly, as this is not a technical tutorial and Grasshopper is a very complicated 3D modeling program. That said, I will post the pattern, drawing files, and source image along with this instructable for those who wish to use it. You can find a pattern online, make your own, or use mine.
[ Materials & Tools ]
1/8" Thick Hardboard – this makes up the four panels and the base (Lowe's has 4' x 8' sheets for $9.00 and will cut down to size for you)
Alternate: Hardboard is sturdy and fairly easy to work with. However, you can use cardboard (which is surprisingly sturdy when laminated) or chipboard, or even thin plywood.
Alternate: Drill or Drill Press
Vellum or Mylar – this is used to diffuse the light (can find at artists supply store)
Alternate: rice paper, trace paper, or other translucent scrap-booking paper
Spray Mount (Supper 77) – can find at hardware stores or artist supplies store, or places like Michael's
Small knife or wire strippers
Lamp cord (with or without inline on/off dial) – Hardware store, less than $6.00
Lamp holder (plastic or ceramic) – Home Depot, Lowe's, Ace. Costs about $2.00
2 small mounting bolts to secure the lamp holder
2 washers for bolts
2 nuts for bolts
Linseed Oil (optional) – used to coat hardboard in order to provide a nice finish and darker material
Small piece of walnut or other wood (optional)- used in an optional detail to help hold lamp together
Super Glue (Loctite Gel)
Alternative: Hot Glue Gun
Foam Brush or Rag - for applying Linseed Oil
