Introduction: 24 - a Ticking Bomb That Asks You to Put Down Your Phone
24 (formerly known as key) is a timer that encourages the users to put down the phone and focus on other tasks, instead of wasting time on the phone. It was designed to be like a bomb to provide a better outcome of behavior change because of its intimidating looking.
Step 1: What You Need?
To make this yourself, you will needing the following materials or substitutes. Also be creative and find your own materials to change or cover some of those:
Push bottom switch
LED ring (NeoPixel)
Tubes where you can buy at Lowe's (I choose the 2 inches ones.)
wood chip board / compressed paper chip board
stickers (round, printed by the vinyl printer)
Step 2: Make the Controlling Unit
Cut the board into 6 pieces in order to put together into a little box to hold the central controlling unit. It doesn't really matter what the size is as long as it can hold all the units:
The key is to make the slot for the phone, based on the size and shape of the phone of yours, you will need to make a customized slot cut out from the box. And there is more to pay attention to:
the width is simple to do: just cut the front face all over (of course make sure it is shorter than your phone so that your phone has somewhere to rest on)
the depth is determined by how much space is taken by the Arduino board inside the box (don't forget to measure the bottom switch) (this step is key, make sure your phone can easily rest on it)
the thickness should be ideally just a bit over the thickness of the phone
Then You will have to solder the wire into the led ring to make it ready. (Data in, not Data out)
Step 3: Making the Bomb
Cut the tubes into equal length. I cut into 7 but you can choose your number.
Then paint the tube and the central controlling unit box with paint. Red would a smart choice.
Step 4: Write the Code
Shout out to Becky (Rebecca Stern) who basically wrote everything of the code!
Step 5: Finishing Up
First binding all the tubes (make sure it is 100% dried from paint LOL) stick the stickers at the both ends of all the tubes. Then fix and LED ring on the box and fix the box onto the tubes. Now you have bomb! No, actually a timer.
