LEGO Reading Light Utilizing Simple Machines

This is a LEGO reading light, that I designed after playing around with levers for a bit. The main motion uses levers and some gearing to sync the two sides. This was designed to fit on my bed's rail, but you can build an adaptor to fit on another place/surface.

All LEGO in photos above.

The battery assembly is easy, just put the pins in the right holes, the other assemblies lock the mechanism to the bar.

Here, the battery box acts as a counterweight to the rest of the light arm.

Just assemble the two colors of beam according to the pictures, you will need to make sure all alignments are correct.

These beams are the levers that extend up and to the side

This is the technic assembly that holds the Power Functions lights.

This stays level because of the lever system that is made.

This is where the red beams contact the frame and clamp.

You need to have a lot of support.

here you are attaching the two sets of beams together in the hinge that does it all

This hinge uses gears to maintain alignment.

Connect the battery box to arm and add the light. Route the cable as described for optimum motion.

We are adding the counterweight and wiring up the light

This is how you would attach it to a square beam or pipe 2.5 studs by 2.5 studs. I hope you enjoyed this simple build and any questions I can answer in the chat!
