Introduction: Light-up Display Case

displaycase with motionlight.

What you will need:

  • 2 Acrylic plates (400mm x 700mm x 3mm)
  • 1 small wood plank (3mm thick)
  • 1 Adafruit Circuit Playground
  • 1 Ultrasonic Sensor
  • 1 Half size breadboard
  • 2 10k Ohm resistor
  • A bunch of wires (you will need a lot of them)
  • Wood glue
  • Super glue
  • Double sided and electrical tape
  • Computer or laptop
  • Optional: 2 Cable sleeves

Machines you will need for this build:

  • 3d printer
  • Laser cutter
  • Soldering iron

Step 1: First of All...

First of all, put the acrylic plates with the stickers still on them in the lasercutter and cut them according to the following plans (If you don't leave the stickers on the acrylic will get stained).And DON'T FORGET to remove the notes in the caseplans otherwise the lasercutter will engrave them into the acrylic; the notes are for later when it comes to assemble.
Caseplans (You need them both):!vHZRSQYC!65UQARAMUwl2-VnJExeRbkY...!2LJTwaaI!kH91XnXG6-d3plw_jGT8pmG...

Step 2: Next...

When the laser is done doing it's thing you can go ahead and glue everything together following the notes in the caseplans using superglue.Make sure to leave 2 holes open, these will be the openings of the displaycase through which you can put in your stuff to display.
After all the glueing is done and set you can continue on with the legs for the displaycase.

Step 3: Print the Things

Using a 3d printer of your choice, print 8 legs using the file below:!KPBHnSCB!mBMpG2Jjf8EQw9vo-MQa2Ij...

Step 4: While That Is Doing It's Thing...

While those are printing it's a good time to get started on making the holder for the circuit playground.
Whip out your wood (the plank) and using a lasercutter cut the following file:!PCRVBYwZ!Jgza2r1c84IComZwxtOfRq3...

Step 5: The Circuit Playground + Breadboard Case

Wire up your adafruit and ultrasonic sensor like the image and download the file. Put the "distance_detector.uf2" file onto the circuit playground using the micro USB cable and your laptop or computer.!2OYlTYLb!JIaCZEn96g0cBdAS2-Q4ZsH...

After this, get started on making the casing for your breadboard to sit in using these plans:!WfBF2CgD!oM4yqO_EL3b6nmQZpCJ3hiG...
Assemble the pieces leaving 1 hole open in the back for your cables to come through.

Step 6: Back to the Legs

Let's get back to the legs.
Using superglue, glue the 8 legs to the bottomside of your displaycase in any way you seem visually appealing.(Make sure you've glued the legs on securely, superglue tends to get a little fussy with 2 pieces of plastic)

Step 7: Almost There

Now let's get this thing assembled.
Put the ultrasonic sensor inside your displaycase towards the bottom and using your wires, plug it into the breadboard same as always. If your cables are too short you can solder 2 or 3 cables together using your soldering iron. Run the cables out of the breadboard back into the circuit playground (Again, if the cables are too short, solder a few of them together) and using double sided tape, put the circuit playground into it's holder you've cut and tape that whole ordeal to the ceiling of the displaycase with doublesided tape.You can make the cables a little bit less messy by using a cable sleeve or if you don't have one, wrap the cables in electrical tape.

Step 8: Yeeeessss....

Now put the breadboard box in a spot of your liking, this could be on top or somewhere along the bottom, it doesn't really matter. For this build, i will put the case on the top. Using doublesided tape again tape the box to the displaycase with the open backside in a way that your cables don't get weird.In other words, just use common sense when placing the box.

And lastly, wipe the whole thing down so it looks nice and transparent.
Now just hook up the circuit playground up to some batteries and turn it on and you've got a displaycase that lights up when you put something in it.
