N5Digital is a multi-disciplinary design company developing products in diverse areas ranging from small home and office gadgets and appliances to electronic devices and new types of narrative, documentary, and educational films with the viewing experience shaped by the viewer's input. All projects follow a similar development cycle including formulation of concept, R&D, engineering and computer design, product implementation in software and hardware, development of application, etc.
The strategy of N5Digital is to develop and launch a product or an application, and market it until it becomes profitable. At that point, the company may establish a subsidiary taking over that particular product or application with the purpose of increasing its market penetration.
Since the core business of N5Digital is design, its Design and 3D Modeling divisions have a central position in the company's operation and, in the long run, define its success. At the same time, support provided by infrastructure is crucial in delivering products to market and ensuring operational viability.

The LEVIATOR is a small, lightweight desk accessory designed to be placed on top of an existing desk to raise the height to comfortable standing level. By creating a higher desk station, the LEVIATOR makes it easy to switch from sitting to standing and back. Ansence of mechanical parts eliminates the risk of damaging power supply wires or cables.
The LEVITATOR requires a much lower investment compared to an adjustable desk or sit/stand workstation.

Rider Vision

The Rider Vision introduces a new video format incorporating multiple selectable video channels of interconnected content, thereby enabling viewers to create their own personalized viewing experience. The multiple streams of video are incorporated into a single multi-channel video stream readable by a player software that makes them available to a viewer on various viewing hardware platforms.


BrightHouse is about adding lively colors to the house windows by installing “copies” of Piet Mondrian paintings: bright and colorful, with a true-art mix of shapes and colors. We brighten up the insides of the house during the daytime by streaming in colored light, and streaming it out at night for enjoyment of the passersby. All designs are assembled of precisely laser-cut translucent Plexiglas.


TapsSight will be more than simply a communication or reading device. Visually-impaired users will be able to access and control information from personal computers, tablets, cell phones, and virtually any electronic device.
TapSight and its main features benefited greatly from discussions with representatives of the American Foundation for the Blind (AFB). We received invaluable recommendations from AFB that we applied to our work on the TapSight device, modifying its 3D shape and various functions.
We intend to develop, manufacture and test TapSight as a collaborative and international effort, a project that relies on people in different countries and with different specialties.

Sub-Z Jeans are beautified by original, intricate and art-inspired patterns elegantly cut into denim with the laser precision. Sub-Z’s will make you look sharp and sophisticated while standing out from the crowd!

Multiplayer Math-Based Escape Game

Matix is a 3D math-based escape game in which players compete to solve math puzzles, challenges, and teasers to escape a series of rooms. As they play, they earn in-game currency BITs.

Energy-Efficient Linear-Stroke

Marine Propulsion Engine with Anisotropic Propeller


Man-made marine propulsion engines use rotating propellers differing from the propelling solutions created by nature with the latter rarely relying on rotating elements.

A conventional marine engine creates the propulsion by using a rapidly rotating propeller. As a result, part of the engine’s energy is spent on to rotating the produced water jet. Since rotation of the water does not contribute to the boat’s propulsion, it is wasteful and reduces the energy efficiency of the engine.

The N5Prop energy-efficient marine engine is designed to convert most of its energy into the useful linear momentum of the boat. The key design element of this engine containing no rotating components is use of a linear back-and-forth stroke dual-use “anisotropic” propeller.
