Greetings humans! ;D This post shall go into the details of how I constructed the tube head for Nickel. I started exactly the same as I did for Prince and Princess, by creating a hole in the bottom of the tube for my head to go through.
I added the blocks of foam so that the helmet, and by extension the entire head, would sit at the right height and angle. This was especially important for Nickel because the head had to clear the shoulders of my box body.
I had my friend Ian do the soldering (and re-soldering) of all my LED circuits for this project. I ran out of time to do it myself. It looks fantastic! I will go into more details of how those were constructed in a later post.
I drilled a hole where each LED would go, evenly spacing the array. Then I farmed them out.
I then taped all the exposed wires so I wouldn't get a crossed wire and end up with an electrical fire. That would be very bad.
...Particularly because it is not so easy to get this costume off quickly...
Then I cut a ring/disc that I glued around the bottom of each hub, so that they now resembled a top hat crossed with a jellyfish.
Then I cut a thin ring of foam core to act as an inner support for my red cylinders, and a circle of a plastic binder to act as a frosted filter. The black rings were my only gluing surface for this entire cylinder.
Alex add an illustration board outer layer to my head. (The sonotube had obtained numerous dings in the garage.)
Then I worked on the cylinders. Using clear tape, I carefully taped together strips of red acetate and curled them around.
I had a friend of my mum's--who has access to a laser cutter--cut me 2 perfect circles in red plexiglass. These were glued to the frosting circle and then the foam ring.
Back in the land of plastic, I carefully glued the acetate roll to the black ring along the top edge. The end result is a bit fragile, but looks quite clean and I am very happy with it. Because of the multiple layers to the red acetate, it did not need a frosted filter.
With the 2 red cylinders done I was ready to assemble. The top-hat-jellyfish were carefully inserted through the neck hole. Then the foam core discs--ones on each end of the tube head and their respective jelly-hat--glued together, making sure that the electrical hub was centered in the middle of the hole. The red cylinders--which were made to fit into the hole exactly--were slotted over the hubs and then glued into place.
Alex says: I LOVE GLUING!!!! D:<
...Which is her way of protesting against all things sewn. :P
The final step was to solder the switch and battery into my electrical circuit to make everything work!
An in depth look at Nickel's circuitry--including diagrams and calculations-- will be coming up in the next month or so, but I will be taking a bit of a break from all things Katamari for the moment. I am also planning on doing a tutorial on how to put together a simple LED circuit. Those will probably be up in september or october sometime.
