The "Infinitum" infinity mirror is an Arduino-powered light table that turns on when items are placed on it, but turns off when they are removed. Designed by Louise-Anne van ‘t Riet as part of her Making Studio course, she wanted to construct a piece of furniture for people who never tidy up, and who leave their belongings everywhere. When objects are placed on the table, it lights up—providing a beautiful backdrop for the artifacts with an illusion of infinite depth. Users are encouraged to tidy up before they leave a room, since the light table will only switch off once everything is removed from its surface. (Check out the video below:)
An infinity mirror is a pair of plexiglass mirrors set up so that the LEDs between them reflect an image back onto the fully reflective mirror.
“Some people never tidy up; why not encourage them to do so by designing a playful and beautiful reminder?”
The table construction includes a piezo sensor switch which, when activated, lights up the LEDs. (The piezo sensor converts vibration to voltage, or voltage to vibration, meaning that makers can use the device as a buzzer for making beeps, tones and alerts, or as a sensor to detect fast movements like knocks.) In simple terms, the vibration of an object being set on the table triggers the piezo sensor. Once the piezo is set off, the NeoPixel Digital RGB LED strip turns on white lights. The piezo, as well as the LEDs, are both connected to an Arduino board hidden under the surface, accessible through the underside of the table. Check out the video below:
Next steps for the project are to add a seal ring under the two-sized plexiglass mirror, and to find a solution for the battery; the table would ideally be place in the center of a room, and plugging it into a wall compromises its simplicity and pure form.
