This is a project was done with a student as part of a class that I conducted which dealt with the principles of FDM 3D Printing.
This project was an exploration in functional 3D Printing to design an object keeping in mind the limitations of the medium. Some basic ergonomic studies were conducted to finalise the frame dimensions, next the joints were modeled in Autodesk Fusion 360. Following this the parts were then printed with a homebuilt RepRap printer. Thick PVC pipes were used to create the frame.
Arduino based midi instrument
The laser harp is an electronic instrument, unlike a traditional harp with metal strings this harp has strings of light. It also does not have a frame: its laser strings stretch out infinitely into space.
Each beam represents a MIDI note. As your hand cuts a beam, the note is played.
Since this harp has no frame, identifying which beam was cut without the use of expensive technologies like Web cams or Kinects becomes an interesting problem as you can’t simply place a sensor array at the ends of the beams.
How the beams are created:
A laser beam is directed to a mirror on the motor. With every step the motor takes, the position of the mirror changes, deflecting the beam in a different direction every time. The steps take place fast enough for the beams to appear as if they are simultaneously present.
How the harp knows which beam has been cut:
Every beam has a corresponding motor position. When a beam is cut, the sensor detects an increase in light intensity. The Arduino then looks for the position of the motor at that instant, and thus identifies the beam in question.

Amsterdam Festival of lights Contest Submission
This installation consists of two parts that synthesizes to form a unique experience. The parent structure represents the large embrace of mother nature and the field of flowers on the ground, her manifestations. Each flower’s energy connects to the parent structure forming a responsive ecosystem. Each individual flower that receives human interaction, blossoms, illuminating itself and transfers the light via its root system to the parent structure creating a point of light for the person who initiated the interchange. As more interactions are collected the parent structure reaches her full illumination at which point the entire ecosystem rejoices with a show of lights.
This art aspires to explore a primordial and present form of biomimicry and to technologically question a concept that has never been more important than in our present age in regards to our ailing planet. We want to tap into a subtle symbiosis, integral to all forms of nature. Ancient and futuristic science believes that we can influence the rhythm of plants through an exchange of emotion and feeling. Nature and it’s processes have been our inspiration at every stage of the design. Evolutionary algorithms dictate the form and golden ratios are seamlessly weaved into the design.
The installation detects human presence by using passive infrared sensors (PIR) along the pathway. Similarly the flowers detects human interaction via PIR sensors on them. Each flower contains rgb LEDs and a motor to react to human presence and interaction, they will be supported by the parent structure. This parent structure is made of tensioned fabric on an rigid aluminum frame lit by rgb LEDs.
