I created this lamp as a solution to my dimly-lit desk. The only requirements I gave myself were that the lamp could be built for less than fifty dollars and would have no physical buttons—I would instead have to create a more discrete form of control. 
After brainstorming potential ideas and browsing through local hardware stores, I came up with a design that uses replacement table legs from Home Depot as lamp arms and 3D printed components for the base, joint, and lampshade of the light. The lamp activates through a touch sensitive metal disc (a repurposed closure plate from the plumbing aisle of Ace Hardware), which is spray-painted black and embedded in the 3D-printed base. One tap turns the lamp on, while consecutive taps brighten and dim the light incrementally. Including all materials, the lamp costs around forty dollars to make.
