Making of Structure 2 - Day 5

Finally, assembling the pieces for the second structure type was underway. On this day, the top cross was glued together and then the reinforcing triangles were screwed in for support and stability. The pieces then were turned upside down and the assembly of the legs were started.

Here is where the structure got to at the end of the day:

Structure 1, Dish Assembly

Silicon sealer was used in order to mount the dish on to the frame.

The sealant was applied by using a silicon applicator gun.

The frame was placed onto the dish.

After drying, the dish was turned upside down and placed on to a table. The eye bolts were fixed into place with a washer on each side for protecting the MDF and by using a square nut and a dome nut for increased stability. The dome nuts were chosen for the ends as a health and safety measure.

Holes were opened to marked up location of Structure 1 for the assembly of eye bolts.

The structure was toppled on top of the dish and the dish as preparation for cabling.

The cables were attached to the frame from the structure.

here The completed structure was raised off the table and placed to location.

Making of Dish Frames - Day 5

MTN 94, Flourescent Azul Blue spray paint was used for colouring the frames.

Two coats of this paint was applied to the frames.

Making of Dish Frames - Day 4

As the dish frames are slightly smaller than the diameter of the dishes, I initially started to sand them down using wet and dry sandpaper.

As this took extremely long amount of time, I was suggested to use a filler grater.

The image below shows how the frame fit onto the dish after the grating process:

After this, the eye bolt holes were drilled to the locations previously marked.

This was done to all 6 frames.

Then, the frames were sanded down as a preparation for painting.

MDF sealer was applied on to the frames.

This was done by using a brush.

Two coats were applied as recommended.

Making of Structure 2 - Day 4

On this day, templates were cut with laser cutter in order to make sure the legs cut were accurate.

After the pieces were cut with a bandsaw, the cut out pieces were sanded down to shape with a wood riffler file.

Here are the correctly shaped pieces:

After this, the center pieces were cut to size, and then their joining part in the middle were shaped to house grooves that interlock with each other. This was done by using the bandsaw and a chiesel. Same process as the 1st structure’s bottom, back pieces.

Installation Set Up

The structures were positioned on site in order to get a feel of how the final installation would look.

Here is a link I found quite educative regarding how to set up a surround sound system (5+1) correctly.

Making of Structure 1 - Day 11

Finally, the wiring up of the first structure was completed.

Here is a diagram of the set up prepared using the Fritzing software:

User Responsive Audio Device Testing

For the installation I am creating, I will be joining 6 sets of stereo speakers with built in amps. I will be using Logitech Z200 speakers. The idea will be that each set of speakers will be positioned against two parabolic dishes. When a visitor comes accross the 1st dish, the 1st track playing will change after 5 seconds to play the 2nd track which will move from that speaker to the other one (panning automation). In order for this to work, I will be using an arduino board, an ultrasonic sensor, a jack adapter and an SD card reader. The video above shows the code working in the manner explained with 2 test tracks.

For the audio files to function properly, they were converted to FullRate 16MHz Stereo files using the converter tool provided by the sound library I included to the Arduino software - ‘SimpleSDAudio.h’.

Making of Structure 2 - Day 3

Here is a diagram explaining how everything needed to be cut:

On this day, the leg pieces were marked for the grooves to be cut.

The table saw was set to size to cut the first part of the groove.

The second part of the groove was cut after readjusting the table saw.

Making A Parabolic Dish - Day 12

Following the recommendation of the sculpture studio technician, Sim Oliver, I decided to finally use damp seal in order to minimise bubble formation while casting the dishes.

Initially the damp seal was poured into a small container.

The damp seal was applied to the surface of the dome with the use of a brush.

3 coats were recommended to be applied for the product to work effectively. Each coat was to be applied 4 hours after the 1st one. This is the dome after the 1st coat:

Here is the dome after the 2nd coat:

This is the dome after the 3rd and final coat:

Making of Parabolic Dish Frames - Day 3

All 6 of the frames were cut:
