Making a Mirror

Video walk-through on adafruit (Thank you Becky!)

  1. Obtain Android device

    We had too many. Sad old devices are ideal. I used a 2012 Nexus 7.

  2. Obtain two-way mirror

    We did this the old-fashioned way, and quested to Canal Plastic Center. A beautiful and highly recommended establishment.

Wiki of places to buy two-way mirrors

Get a mirror at least as large as your Android device. My mirror is 6"x12" with 1/8 thickness.

  1. Sticky stuff for mounting

    Our trickiest problem was figuring out how to mount everything with minimal damage and error. We eventually discovered reusable double-sided adhesive, which is amazing.

We're using it both to mount the mirror to the device, and the device to the wall.

  1. Attach black backing

    We used black construction paper. If your device and mirror are awesomely identical in size, you can skip this.

Note: You want to glue it well, so the backing doesn't tear when the adhesive is holding it.

  • Cut a piece of black backing the same size as your mirror
  • Decide where you want your device to show through. We did upper right. Leave a border all the way around for adhesive.
  • At that location, carefully cut a hole in the backing the same size as your device
  • CAREFULLY glue the backing to the mirror. We used spray adhesive, and practiced how we would pick it up and lay it on the mirror a couple times before going for it. We also wore black surgical gloves.
  1. Adhesion

    Fire up the app on the device.

Put the adhesive along the bezel or edges of the device. Line up the mirror and stick it on there.

  1. Wall spot

    You probably want a long usb cable. Find a wall spot where you can keep the device plugged in.

Put a bunch of adhesive on the back of the device, and stick it on there.


At the heart of this project, is 'put a mirror on it'. Check out alternative mirror projects and feel free to add your own reflections
