Keep Walking (public art version)
As a recreated extension from “3D Green Man Cube,” “Keep Walking” is a larger public art work of aluminum structure. It has 1000 glass lampshades, 1000 SMD LED Printed Circuit Boards, Arduino Mega 2560, 5mm acrylic sheets, 8 black sheets covering the top and bottom part, and 4 transparent sheets protecting the middle LED cube part. The volume of the creation is 300cm (H)*100cm (W)*100cm (D) placed outdoors at Corridor of Wine Pots, which is one of the famous landmarks at Taipei National University of the Arts (See the stimulation diagram in Figure 7). The installation is three meters in height and one meter in width with the LED cube installed in the middle of the creation because that is the most suitable height for audiences to watch.
Figure 5. The schematic diagrams on the first row indicate the respective visual effects in the morning and at night. The images on the bottom right are the actual installation of the work.
The 1000 spots of light are created with 1,000 pieces of SMD LED Printed Circuit Boards and glass lampshades of the same number. The hole on each glass lamp shade is manufactured by a laser cutting machine for the purpose of threading electrical wires through it. Since the whole installation is about 100 kilograms, it probably needs 4 to 6 people to move it. Incidentally, in 2016, before the installation was put on display at the first Kuan Du Light Art Festival (KDLAF), four strong typhoons, Meranti, Malakas, Megi and Aere , hitting Taiwan caused serious damage to many places. In order to protect the artwork from the storms, we moved the installation three times for about 100 meters from an open-air corridor to an indoor place.
Figure 6. These photos show the construction process of a bulb in the installation. The image on top right indicates an acrylic base of a bulb cut by the laser machine with a piece of SMD LED PCB affixed by two screws. It is then sprayed black to make it lightproof.
Figure 7. A line of 10 bulbs strung together and connected to a column pin of Arduino board is shown on top left. These bulb lines then were affixed to the aluminum extrusion structure with screws, washers, gaskets and nuts shown in the middle pictures on the first row. Different color electrical wires are used to classify specific layers of the cube. The installation is being tested by running the Arduino code to animate bulbs on different layers.
