The Geared Head of Feelings
A 3D-printed kinetic art project by Stefan Kneip
The Geared Head Of Feelings consists of 35 different gears moving in two layers.
The gear mechanism is driven by a small 12 V electro motor on the backside. With a mask in form of a head the installation symbolizes the small running wheels inside our heads which are controlling our minds and feelings.
An Arduino based controller electronic is the "brain" of the installation. It can operate in different modes which are adjusted by means of a push-button with integrated LED.
The red push-button-LED is on: The gears are standing still, only the LED illumination is on (silent mode).
The red pushbutton-LED is on: The gears are moving and drive the "Feelings Wheel". The LED illumination is on too.
The red pushbutton-LED is blinking: The integrated motion detector is activ (must be attached). As soon as a motion near the installation is detected, the LED illumination is switched-on and the gears begin to move. If no motion is detected for about 30 seconds the electronic switches off the gears and the LEDs again.
The red pushbutton-LED is off: Everything is switched off other than the arduino circuitry. (Power consumption in this mode is about 50 mA).
By pressing the pushbutton you can circle through these modes.
You can hang-up the frame like a picture or use the stands to dispose it on your desk.(see picture).
The motion detector is attached with small Nd-Magnets on the top side or buttom side of the frame (drill 8 mm countersink holes in the Ribba-Frame and glue the magnets in these holes).
What you need:
1x Frame Ribba 25 cm with (IKEA)
2x LED-illumination LEDberg 12V
1x Gearbox motor
2x sheet of AlDibond 25 x 25cm of 2 mm thickness
40x bearing 3x8x3mm (MR83ZZ)
Screws 3 mm with a lot of washers and self locking nuts
PIR-Motion detector (https://www.adafruit.com/product/189)
The circuit board attached (feel free to build one).
See picture GearsAssembly for details how to assemble the gears on the mount platform:
Press the bearings in the gears. Assemble everything in the mounting frame first.
Print the parts beginning with a w in white colour, the ones beginning with a b in black.
