Cellular Graffiti Printer | 2011
What if people would expose and visualize their SMS text messages on buildings? If your Facebook status would be printed on a real, physical wall? What if you really checked in when you check in?
The wall printer takes the wall status concept back to physical dimensions.
Inspired by old-school pin printers, the wall printer is a manually held device using seven markers to print digital messages on any flat surface. Seven individually controlled servo motors move the markers up and down, drawing dots and dashes.
When you manually slide the printer over a wall, the servo motions are carefully timed to produce text messages.
Connected to a cell phone, the printer can be directly fed by SMS text messages, Facebook statuses, GPS coordinates or practically by any other digital data source.
It uses a IOIO board to connect the physical electronic parts to an Android device and control them from an Android application.
This project was done with help and advice by Ytai Ben Tsvi, IOIO inventor and friend :)

Robotic drums party installation | 2011
Robotic drumsticks were playing on steel barrels at an abandoned textile factory party, Bar Yochai, Tel Aviv.
Beats were generated automatically, at real time, according to the music played by the DJ.
The system listens to the music played, analyses it and controls the drumstick's beats accordingly.
People choose which drumstick play at any given time by making shadows on them.

Robotic Drums | 2010
by Jonathan Rubin, Liat Segal & Assaf Talmudi
18 Darbuka drums and 36 robotic arms are controlled via wireless communication. Drum music is composed and played at a music sequencer on an iPad.
Thanks to Ben Handler and Eyal Talmudi for playing with us! :)
The making of...
So, what do we have here... 18 darbuka drums, each drum is played with two sticks mounted on servo motors and is lit by a super-bright 1W LED. We chose to use drum sticks mounted on servos (rather than the traditionally used solenoids) in order to achieve a powerful sound accompanied by a visual effect of a drumming circle.
Each of the 36 servos and 18 LEDs is controlled independently in real-time. In order to play (and light) our drums, we needed to control 54 channels wirelessly. To this aim, we built nine control units, each consisting of an Arduino and a XBee radio transceiver. Each unit was designed to control two drums (4 servos and 2 LEDs):
A master netbook, running Max/MSP, sends control commands wirelessly (via XBee radio transceiver) to all control units.
As a final touch, we added an iPad interface to give an easy and intuitive way to interact with the installation. OSC protocol was used for wireless communication between the master netbook and the iPad (via Wi-Fi).
Three modes for playing the drums in real-time have been designed. The Sequencer mode allows composing specific beats for each of the 36 drum sticks. At this mode users can design and play loops and when happy with a loop, save it as a preset. Users can shift between previously saved presets at Presets mode.
Users can also play the drums by 'hitting them' at a location based Intuitive jamming mode.
At both the Sequencer and the Presets modes, the user can control the BPM of the loop by either switching a dial or shaking the iPad at the desired tempo.
Additionally, the user can switch between parts of the loop (and either play the entire loop, 1/2, 1/4 or 1/8th of it).

The project was presented at the Bat-Yam international biennale of landscape urbanism, September 2010, as a part of the 'Green to Blue' ecological street project, by Matanya Sack and Uri Reicher. During the biennale, electricity generated by wind turbines and photovoltaic cells was used to operate the robotic Darbuka drums. The drums were mounted on the wind turbines columns, creating a hybrid, digital-mechanic drumming circle, a futuristic-traditional acoustic space.

DIY Multi touch screen
Our low cost multi touch screen was built using the frustrated total internal reflection principle.
Total reflection occurs when light travels from a medium with a high refractive index to a medium with a lower one. The light is then trapped within the first medium.
In our case the Infra-Red beam of light, transmitted by IR LEDS, remains trapped inside an acryl surface, since the refractive index of the acryl is higher than that of the air surrounding it. When touching the acryl surface, light bounces off the finger out of the surface.
The touch-screen is composed of an acryl surface, a standard projector connected to a PC, a mirror, an IR-sensitive webcam and a foldable, portable construction:
The acryl surface is used both to display the PC output and to sense user's input.
The acryl is coated with diluted silicon which enhances the amount of reflected IR light due to user's applied pressure on the screen.
Then, a sketch paper sheet is placed on the silicon layer to protect and isolate it. A diffusing material is layered on top of the sketch paper. The diffuser is semi transparent, allowing quality projection, on the one hand, and blocking access visible light from the other side of the screen.
The entire surface is framed with an aluminum frame which has 112 IR LEDs drilled into. The LEDs' tips, sticking out of the frame, are coated with black silicon. This is done to reduce IR light spilling in the wrong direction.
To keep everything together and protected from short circuits, a wooden frame is applied around the screen.
The 112 IR LEDs in the aluminum frame are divided into 14 sub-circuits, each containing 8 LEDs and one resistor. The 14 sub-circuits are connected in parallel, producing a circuit that consumes 1.4Amps and 12Volts. It is powered by a standard PC power supplier which is short circuited to work without a motherboard.
The reflected IR light is detected by an IR-sensitive webcam. We used the Microsoft VX-1000 webcam. To make the camera sensitive to IR light we removed its internal IR Filter. To make it insensitive to visible light we applied several layers of burnt camera film.
This project was done as a part of the Out Of the Box Week #IV at Microsoft Innovation Labs, Israel, by Hen Fitoussi, Kfir Karmon, Omer Ramot & me.

~ SEND YOUR SOUNDS ~ | Plate Recorder
In collaboration with Roy Maayan
At times of information overload, we are constantly exposed to visual, auditory, and textual inputs. Social networks and news feed create new expression channels, yet, at the same time, challenge our ability to genuinely hear, see, and touch.
Plate Recorder is a digital era homage to analog, connecting sound, visual and matter in the physical domain. Ready-made ceramic plates are used as a medium for recording local real-time sounds. A custom-built painting machine is etching sound waves, creating ‘ceramic records’. Recorded plates are collected, creating a physical archive of sound and being.
The project was first exhibited at the Cluj Ceramics Biennale, 2017. Read more here!
~ SEND US YOUR SOUNDS ~

~ HOW ~
Send sound\video files via your favorite platform (dropbox\wetransfer\googleDrive\pigeon\...) to
plate.recorder@gmail.com
Don't forget to also send a short text + date + place.
