Colour Injector

Arduino makers project - Colour Injector


Colour injector is an interactive multi-coloured lamp designed as a physical expression of the way red, green and blue light are used in digital interfaces to create a full spectrum of different hues.

Syringes suspended below the lamp are connected to another set inside the body using clear tubes so that the ink can be seen moving towards or away from the lamp. The handles of the syringes inside the lamp are attached to sliding switches connected to an Arduino microprocessor that controls the colour output of rings of RGB LEDs. The system allows people to gradually change the colour of the lamp light in an unconventional way by providing a simple and intuitive interface.

What have you made?

I have created an interactive multi-coloured lamp with a physical input interface.

What gave you the initial inspiration?

I was inspired by chemical reactions in solutions and their gradual colour transitions. I wanted to develop an interface allowing people to control this process at any speed they like.

What is the original idea behind this project?

The original idea was to create an analogue converter from CMYK to RGB colours. So initially, there was a prototype with 4 syringes. However, I decided to simplify the concept and made a direct representation of RGB colour system. The lamp was designed in 2013, as a BA project at BHSAD, Moscow. The challenge was to create an ‘in-n-out’ system where an unusual analogue/digital input was connected with an analogue/digital output in order to make some fun and provoke people into emotional responses.

How does it work?

1. There are 3 pairs of syringes connected hermetically so that the external syringes affect the internal ones.
2. The internal syringes change the position of three potentiometer sliders.
3. The Arduino converts the analogue input into a digital output data.
4. The signal goes to multicoloured LED tape wrapped around a cardboard tube.

How long did it take to make it real?

It took a week to develop an idea and two weeks to make a working prototype. Then, I have spent one more week to design the final product, where all the electronic was hidden inside a case.

How did you build it?

I used an Arduino Uno, 3m multicoloured LED tape, 36W power adapter, aluminium and a wooden framework, cardboard tube, white plastic sheet for the lampshade, and 6 plastic syringes with inked water. An additional module and a breadboard were used to connect the contacts in a more convenient way.
