Wifi Power Strip

WARNING!

BE CAREFUL WHEN WORKING WITH 120V. IF YOU ARE NOT EXPERIENCED OR SUPERVISED BY A PRO, PLEASE ASK FOR SOME HELP. 120V HURTS!

Step 1: HOW TO BUILD YOUR OWN WIFI POWER STRIP

HOW TO BUILD YOUR OWN WIFI POWER STRIP

I wanted to find a way to make my apartment smart without investing a lot of money. That’s why I have decided to make a wifi power strip that I can control over my phone. In this instructable, you will learn to build a wifi power strip and make any device smart while controlling it from your cellphone.

Step 2: Supplies

Supplies

Step 1 Get all of the materials in the list.

Power Strip

4 channel relay

Wifi arduino controller (ESP8266 ESP-12E NodeMCU Using Arduino IDE)

Step 3: Dismantel the power strip.

Dismantel the power strip.

Cut the metal gold strip between the plugs to separate the conection in order to control them independently.

Step 4: Connections

This part is tricky. Be extra careful when plugin in to the wall.

First grab the in cable from the wall and add 4, 16 gage wires. Connect 4 wires to 3 plugs on the same side and 1 usb side.

Connect 4, 16 gage to the other side of the 3 plugs and the usb wire.

Connect those four wires to the relay slots. Use only the sides on the relay.

Connect 4 wires to the other side of the relay and then to the 16 gage wire that goes to the wall.

Finally connect the ground to the ground in the wire that goes to the wall.

Step 5: Connecting to the ESP8266 ESP-12E NodeMCU Using Arduino IDE

Download the softwares for the wifi board.

Use the 5v to power the relay.

Use d1-d4 to control the relays.

Ground from the relay to ground from the wifi board.

All set!

Step 6: Code

V+: an interactive climbing wall

If you have ever climbed or bouldered before, you know how much fun and addictive it is. With V+ I decided to add interaction through the use of LED lights which have been programmed to display different levels of climbing through the use of the Bluetooth LE Module from adafruit. Through the Adafruit Bluefruit LE Connect App, anyone can choose the level they wish to try. This first prototype of the wall is currently installed at the PoD Gallery at SVA, it will be up until January 10th 2017. Come visit!

For a peak into the making process for this prototype please visit the Instructable page. The process was long, but this was a super fun piece to make. From mold-making the holds, to doing the circuitry, it was worth the time and effort, specially now that I can climb it.

 

I am specially excited about finding a permanent place for the wall at PoD. Climbing is very fun, and good for taking a break and de-stress.

Thank you to my classmates and our awesome professor Becky Stern for a wonderful class this semester.

Have you ever listened to a musician play guitar near a campfire? Something about the flickering lights and shadows creates a mysterious romantic ambiance that’s become an icon of American life. Sadly, most of us spend our lives in the cities, and rarely have a chance to experience a fireside serenade… Until now.

See the demo-video below, as well as an Instructable so that you can make your own!

 

Wifi Power Strip

I wanted to find a way to make my apartment smart without investing a lot of money. Thats why I have decided to make a wifi power strip that I can control over my phone. I can plug in any device to the plug and turn it on and off form my cellphone!

So I cut the connection between every plug to make them individual. There is one for the USB connectors to the left, you can see a blue and red cable coming out and then the plugs, I cut the metal strip that connected them to make them individual plugs. Then, I connect each plug to 1 of the relays including the usb connectors and I plug the Relay to the wifi controller and Vuala, I have my smart power strip!

HOW TO BUILD YOUR OWN POWER STRIP.

Step 1

Get all of the materials in the list.

  1. Power Strip
  2. 4 channel relay
  3. Wifi arduino controller

Step 2 – Dismantel the power strip.

Step 3 – Cut the metal gold strip between the plugs to separate the conection in order to control them independently.

Step 4

  1. Connect 1 side to all positive, in this case blue and the other side negative. Then plug in the positives to the positives in the 4 channel relay and the negatives in the negatives.

Finally plug the ground into one of the 4 channel since the ground is shared by all them and connect the 4 channels to the wifi controller.

Now you have to figure out the code!

Final Project Proposal: DIY Smart Litterbox

As adults, we have the right to only be responsible for our own poop. But when you own an indoor cat, you give up that right. Your cat’s poop  becomes your responsibility.

It’s never fun to find out that it’s time to change out the litter in your cat’s indoor bathroom (i.e. litter box). Smell is the key indicator, and who likes to sniff around for a bad smell?

Enter, the smart litter box sensor:

img_4690-litterbox-storyboard

The sensor detects the excess ammonia gas emanating from an uncleaned litter box. In response, it has two outputs: it lights up two LEDs (behind each eye in the little kitty head), and it sends an SMS (text message) to the keepers of the litter box (i.e. the pet’s owner(s)/parent(s)).

I’ve already prototyped a non-texting version of this product:

img_4641_wiring

< Soldering/wiring process for sensor and LEDs

img_4648-3d-print

< 3D-printed enclosure for the sensor, LEDs and wires (it’s too small!)

And now it’s time to add the text-sending functionality to the equation. This will require:

  • A WiFi-capable circuitboard, like the Huzzah Feather (already purchased)
  • Getting my existing code to work on this new board (work in progress!)
  • Adding a text-sending functionality by parsing through how-to guides like these:
  • 3D modeling of a new container that fits my wiring and my new circuit board!
