Mood Box: Final!

While waiting for the final project to cure, I worked on my mood box. Yeah, this is the current (and final) version of it! The mood box was made slightly larger than the final, so as to allow the final to fit inside it. It was made from acrylic plates (known locally as perspex) that formed a hexagonal box.

Six LEDs were wired onto the bottom of the box. These were activated by a press-on switch in the center of the box. When the box was placed on a horizontal surface, the switch activated the LEDs. The LEDs were connected to a custom battery pack that housed two 9V batteries. The pack supplied 18V of electricity in total to power the LEDs.

This is the final appearance of the box. The walls were "frosted" by using spray paint. I used Royal Ivory for the effect. The box's base and cover were not frosted. The cover was attached to the box by means of a metal piano hinge riveted to the cover and one of the walls. In this picture below, the light did not diffuse to the top of the box due to the final project resting inside it. The final project was supported by six support walls that also helped to strengthen the box's structure.

At last, my mood box is completed. It underwent many changes in concepts and design. The final concept conveys a sense of "nature".

Final Project: Updates!

I'm back with some updates for my Final Project. Previously, the pyramids were made from resin triangles which were attached to form the structure. The problem was there were gaps in between the plates. I tried to fill them with resin, but that resulted in a textured surface. So I decided to make solid resin cast pyramids instead. Below are the masters for the solid pyramids. They are made from a mounting board base coated in automotive putty and glazing putty. The one on the left is the raw master, with the sanded one at right.

These are the completed pyramid masters. The dents left by the automotive putty were filled in using glazing putty. The master was then sanded using 240 grit sandpaper. This was then wet sanded using 1000 grit sandpaper to achieve the surface seen below.

The masters were then attached to a mounting board base and retaining walls were set up to prevent the silicone rubber molding material from flowing out. This also produced a strong and stable free-standing mold that could be used more effectively.

This is the mold, awaiting curing. The silicone rubber was mixed in small batches (about 2 tablespoon fulls per batch) and poured onto the master until they are totally covered. I used about 500g of silicone rubber for this.

Once the rubber had cured, the mold was pulled out from the master and this is how it looks like. I placed small beads that represented risk (dice), perseverance (tortoise) and achievement (star) in each of the three-sided pyramids. The pic below shows the LED being propped for casting. To achieve a "floating" effect with the beads, my other half told me to pour in a bit of resin, let it cure and drop the bead in it. This was then topped up with more resin that completely covered the LED. The four-sided pyramids only contained LEDs, so there was no need for the two-stage casting. A small piece of PVC sheet was also placed at one of the corners to act as a hinge.

After the 9 pyramids have been casted, it was time to put them together. The four-sided pyramids were each attached to two 3-sided pyramids... err... tetrahedrons. The two terminal pyramids have one hinge each to be attached to the central pyramid. The design mimics the craft board mock-up that I made earlier.

This is how the final shape of the structure looks like. This is the raw stage, and it still needs to be trimmed and then the LED terminals need to be connected. My other half helped me with the wiring. =)

This is the structure after it has been trimmed. It is now similar to the initial mock-up in form and function. The trimming was done using a dremel tool with a rotary cutter. The edges were then smoothed out using a polishing bit. You can also see the Mandalorian dagger that my other half has been working on in the background!

I used a total of 1 kg of silicone rubber, plus another kg of resin on this project. Not to mention dozens of LEDs! Now, all that's left is to connect the terminals and watch it glow!

Final Project

My mood box had evolved over the space of the time I took to write this post... about 5 weeks? It's no longer the tower based on Minas Morgul, but it still retains the hexagon concept. It's now being redesigned and reshaped to house my final project! Here are some pics of the final project. It's supposed to summarise what I've learned for this semester. Structure, design concepts, history...

I decided to stick to using resin as the main material for my project. I did this because of a few reasons. We were told to explore new materials for this project. Our lecturer even forbade us to use mounting board and UHU glue! Since I was already using resin cast on the mood box, I decided to try applying the same technique on the final project. The resin that I am using is also translucent, which will help me a lot because I intend to put some LEDs inside the pyramids. My other half said that the project reminded him of Tony Stark's RT, the arc reactor that powered the Iron Man suit!

Ready for installation of LEDs

The final project is still based on the hexagon. It's been broken down into triangles and reassembled into pyramids. Structurally, pyramids are very stable, and historically, pyramids have been very significant. I have designed it so that it's shape can be changed. The design is now "organic". The nine pyramids that make up the structure are connected to each other via wire loops on the edges. The center pyramid holds the other eight, becoming a central "hub".

I am now working on another version of the project, this time involving solid resin pyramids with embedded LEDs. I have reverted to the original design of the mock up due to stability problems with the newer design. In this configuration, the pyramids are attached at the walls instead of the points. More pics and updates soon!
