An easy way to explore topics in a more memorable format is by including them in ‎a craft project! Our example, by Emma, is a dinosaur, though of course you can ‎choose any topic.‎

We Used:

  • ‎3mm Black Value Acrylic Sheet
  • ‎‎0.5mm Black Polypropylene Sheet
  • ‎LED Strip Kit
  • ‎Heat Shrink (optional)
  • ‎Then just add - Last Cutter, Printer, Paper, diffuser material
  • These DXFs‎‎

STEP 1 - LASER CUTTER:

Laser cut the box and inner panels. They should appear as below. Make sure that ‎on the box sides (the four thin pieces) the interior vertical lines are only kiss-cut ‎and not cut all the way through. These are intended to provide friction to hold the ‎polypropylene panels in place.‎

STEP 2 - CONSTRUCTING THE BOX:‎

Construct the box as shown below, making sure to be careful while pushing the ‎finger joints into their corresponding holes. The scored lines should face the inside ‎of the box.‎

STEP 3 - PREPARING THE LED STRIPS: ‎

The flying leads on the USB cable need to be Soldered to the pads on the LED ‎Strip. Once they are in Place, either use heat shrink as we have or use electrical ‎tape to insulate the joints.‎

STEP 4 - ADDING THE LEDS TO THE BOX:

Feed the strip through the hole in the bottom right of the box and use the adhesive ‎on the back to stick the strip against the back of the box.‎

STEP 5 - DIFFUSER:‎ 

Pack the box with a layer of a light diffusing material. We used wool batting, but ‎packing foam or similar materials would work well too.‎

STEP 6 - ASSEMBLY:‎

Stack on the polypropylene pieces as shown. In the case of the top layer, this is ‎where the layer of paper will want to go. In order to achieve a sharp and clear ‎shadow at the front, we taped the paper to the top layer of polypropylene.‎

STEP 7 - TURN ON AND TEST:‎

Turn on the LEDs! You can see how the closer to the paper the silhouette is, the ‎sharper and darker the shadow appears.‎

‎Fun Facts:‎

The Micropachycephalosaurus - (Mike-row-pack-ee-seff-a-low-saw-russ)‎

Was discovered in China in 1978 and has the longest name of any dinosaur. It was ‎likely only about a metre from tail to nose when fully grown!‎‎ ‎
