How To Make an Android Smart Home Mirror

Make a mirror that’s also a display! Use any Android device and some two-way mirror plastic to whip up a smart home mirror, using Hannah Mitt’s code on Github! This guide will walk you through my process of installing Hannah’s app on my Nexus 7 tablet and installing it at home. First up be sure to read this page and download the code:

The app has modules for date, weather, chore reminders, stock prices, XKCD comic updates, news headlines, and more. I find the temperature display particularly useful for deciding which jacket to grab on the way out the door.

I had never done any Android development before (though I did make my phone unlockable with an NFC ring), so I think it’s safe to call this project beginner-friendly. It took a little tinkering to get it working and then some crafting to assemble the mirror, but was very satisfying at each incremental step.

Besides your Android device and its power supply (and a long USB cable), for this project you will need:

  • two-way mirror plastic (see-through) – I got mine at Canal Plastics but you can also get it online
  • double-stick tape
  • velcro tape
  • black construction paper (or dark file folder)
  • packing tape
  • velcro tape
  • scissors
  • power run to your mirror’s desired location

Talking Dog Collar with Bluetooth Control

Make a bluetooth-activated talking dog collar for Halloween or just to show off at the park! This intermediate electronics project was inspired by Dug from the movie Up– his talking collar translates his thoughts for communicating with humans. Using the Audio FX board and Bluefruit Micro, this project enables you to trigger sound samples through the Bluefruit LE Connect app for iOS and Android. The sounds are played through a mono amp connected to a mini metal speaker.

The collar itself is made from a leather belt, with 3D printed “greebles” to make it look like the collar from the movie.

It’s easy to adapt this circuit for any phone-triggered audio project by swapping out the sound samples!

Mystical LED Halloween Hood

Create glowing eyes for your costume! This project is ideal for any character with glowing eyes, like the Black Mage from Final Fantasy, Jawa from Star Wars, or Orko from He-Man. Two NeoPixel Jewels can appear any color or animating pattern, and they are driven by a GEMMA microcontroller powered by a 500mAh lipoly battery in a 3D printed pocket.
