Hi everyone! I’ve been working on Ysera, but haven’t posted anything, so I’ve got a lot to show you! So far I showed you the custom shield I made myself, teeth/accessory making a little else. Today I’m showing you the core pieces put together and the circuit/lights to illuminate the eyes and mouth.
To make the structure I shaped a bunch of newspaper together, taped it, and made a paper mache shell out of the pieces (one for the neck and one for the head). This time, I wrapped the pieces in cling film to make the separation easier (once dry, you make it hollow). It did help a lot, but was tricky at first! This part of the process was taken from Dan Reeder’s book “Paper mache dragons”, which I really recommend. There’s a lot more info and pictures onto how to do it, so pick it up if you’re interested!
For this project, I had to do things a bit differently though, since it would have cables and light bulbs inside. I taped the inside both the neck and head pieces with very thick duck tape so avoid light going through the skin or cracks, and covered the tape with a layer of paper mache so the cloth would later glue onto it. I also added a bit of onion paper behind the eyes to act as a diffuser, since the three light bulbs were too obvious looking from outside.
I used seven high quality and VERY high intensity LEDs with a wavelength of 490, which is very close to the cyan/greenish colour that Ysera emits. Each LED has a resistor attached to increase their life (otherwise they can burn out pretty quickly). They’re powered by two AA batteries that can be easily swapped in and out from the back of the shield. I also hacked an on/off switch in. Once the cable length and angles of the light were adjusted, everything was soldered in place and secured with industrial-quality hot glue that won’t melt with the heat. I made sure to insulate all of the circuit pretty well when gluing the parts together and everything went just fine. The lights work and it looks amazing! Hmmm, I should have taken a picture of that 🙂
