Introduction: Hyper Portable Light Projection

About: Hi! My name is Hans, I live in Scandinavia where I build whatever pops up in my head, out on to my sketchbook and finally into my hands. My projects here are my favorites and I hope some might inspire you. Rem…

I made a projector from found objects.

  • Bottom of a trashed guitar
  • Lens from a broken slide projector
  • Handel found at a flea market

And of course some stuff I had laying around the workshop.
I really like the shape and getting it to work made my day:-)

Step 1: Installing the Interior

The base was given due to the dimension of the guitar. The front has a foot for adjusting the hight. The magnifying glass was harvested from an old overhead projector. The light is a 10w led light. The front lens is adjustable by turning, a rivet is placed upside down so it keeps the threads from the lens accurate. It is hinged in the back for easy access to the whole interior. There is room for a 12-volt battery pack inside.

Parts used:

  • Adjustable lens
  • Rivet for holding the lens
  • Magnifying glass
  • 10 w led
  • 12-volt battery pack
  • On-off-on switch
  • DC connector
  • Wires and connectors
  • Lock, hinge
  • Handle
  • Adjustable foot

Step 2:

The lens and the light can be adjusted for best focus. Since the lid is closed changing the slide image is done manually by opening the lid.

Step 3: Up on the Wall…

Moment of truth… it works! What will be projected is the next step, I'll be working on text and image concepts, look up!

Big smily!

Step 4: Exterior…

The name is what makes the game:-)

External battery pack at the rear DC connector.

Step 5: It's All About the Wrapping

Side view, looking good!

Inside and closing.

Bottom with an adjustable leg.

I really love this little fella, all thanks to a thrashed guitar and some optic leftovers:-)
