Outlet Master


Felix and I built the brain of an aquaponics system. It is an outlet box with four outlets each of which is controlled by google calendar. It turns out that this Google calendar controlled outlet box has plenty of other applications beyond aquaponics.

Aquaponic Farm

Felix and I have planned our aquaponic system. We are using a steel wire rack as the base. We will have a 20 gallon fish tank with two 10 gallon (36″x18″x6″) grow beds for a 1:1 fish tank to plant bed ratio. We will use a Four outlet power relay module to control the pump, grow light and fish food. This relay module will the control center of the operation. With this we can control remotely when the plants are watered, receive light and when the fish are fed. We are currently in the process of procuring everything we need for the project.

Here is our working Instructables tutorial

I am looking at this tutorial: https://www.instructables.com/id/Simple-Arduino-Controlled-Aquaponic-System/

Felix, Helen Marko and I are going to work on it the aquaponic farm.

Infinity Mirror: “the Dad Joke of Halloween Costumes”


Whoa! It’s like you have a hole in your chest!! Nice!!!

—Random Parade-Go’er






  • Shortbread cookie tin with cookies
  • 2x acrylic one sided glass same diameter as cookie tin
  • Electroluminescent tape
  • 4xAAA battery inverter
  • Suspenders
  • Black hoodie
  • Rivets


  1. Eat the shortbread cookies
  2. Laser cut the one sided glass into circles
  3. Stick EL tape to inside of the walls of the tin
  4. Rivet the tin to the suspenders
  5. Glue the mirrors into place
  6. Cut hole slightly smaller than the tin into the chest of the sweatshirt
  7. Punch holes every 1/2″ into the lid of the tin
  8. Sew lid to sweatshirt.
  9. Don the infinity mirror and blow everyone’s mind and induce barely-audible chuckles

In the future:

  • Use more robust housing than the tin such as ply wood.
  • Make a second one on the back


Much fun during the parade!


Infinity Mirror


  • One way glass
  • Electroluminescent tape
  • Relay
  • Arduino
  • Shortbread cookie tin

To do:

  1. Laser cut the acrylic to 10″ diameter circles
  2. Spray paint cookie tin black
  3. Attach EL tape to inside of cookie tin
  4. Program the Arduino following this tutorial: https://www.instructables.com/id/Control-EL-Wire-with-an-Arduino/

Status: I just received the one way glass in the mail, I am still waiting for the EL tape, and I still need to source the relay.
