SLAM JUNK is an arduino-powered led office basketball hoop. Everyone knows that it's a myth that technology has reduced our use of paper of course, but there is also a unique gratification with crumpling up drafts and throwing them into the trash bin. Thus was born SLAM JUNK. Indeed, there is a long history of office-based basketball hoops, and I want to take things to the next level by integrating motion sensors, light and sound effects—all powered by Arduino. 


All about trash

“Trash is the treature that people put in the wrong place.” This is a very famous saying in China. Everyone has the similar experience about pouring trash. There are a lot of things we might face everyday, such as the smell, the hygiene problem, the garbage classification, etc. “Trash is disgusting” is a saying I have been always hearing. And then the result is people would choose to ignore the trash they create.

As a result, I wanted to make a design not only for solving the practical issue, but also for encouraging people to interact with trash in order to raise their awareness, bringing some value to trash.



One day, I noticed my friend shouting 'slam dunk!' when she tossed a piece of crumpled paper into the trash can. It was a simple step to add a bit more delight to the experience—SLAM JUNK is an interactive device that provides a bit of silliness and joy. Sink the shot and watch it light up and cheer for you. Or hang it over a trash can to add a bit of tech fun to your daily life.

The way SLAM JUNK works is simple: When triggered, an infrared sensor detects the paper and triggers the LED light strip and speaker audio. (Users also can also switch off the sound effects if it becomes too distracting for their workmates; the running lights will still animate if the shot is made.)


Slam junk first prototype

I made a very rough functional prototype to test the feasibility and possibility of this idea in order to gather some informations and user feedbacks for the next prototype.


SLAM JUNK Second prototype

This is the second prototype of SLAM JUNK. I try to simplify the normal basketball board and hoop, simultaneously, I also want to minimize my product size, depends on the Arduino things size. Because it will be hanged in the office or at home, so my design direction is that I want my product style is more like a household product or like an electronics. So I chose wood to make a hoop and back box and use white acrylics to make product coordinating with white wall.

Slam junk Final prototype


This is a prototype testing before I put all the electronic components into 3D printed model. There are two buttons making this prototype functional. One button is the on and off switch as well as LED light switch. The second one is for sound. If the user think the sound effect is annoying, they can just switch on the LED light.
