Before I got the servos, I hooked up a simple joint using some simple aluminum beams I hound at the hardware store. I screwed them loosly together in a Z shape so that one piece would hook up to the mask and one piece would hook up to the main part of the helmet. The piece in the middle would be the hinge to hold it open. I just put these on with a whole lot of gorilla glue which i will paint over later.
When I finally got the servos I needed for the face plate, I found this page on the RPF. This shows a different way of wiring the face plate and explains that you could hurt the arduino by running the servos through the 5v pin on the arduino. I then tried wiring the new diagram up and I couldn't figure out how to get it to work. What I came up with was using the original wiring but run the servos straight from the battery instead of through the arduino. Unfortunately there was not enough power going to the servos so instead I wired the servos to a separate battery. The one important thing I had to do was to make sure a wire hooking up to the negative wire on the servos ran to both batteries. This is so you can complete the circuit with both the battery for the servos and for the pin that the arduino uses to tell the servo when to move. After fine tuning the programming to fit my helmet, I glued one more of the aluminum bars to each of the servos for a better look and farther turn radius for the servos. Lastly I got some 90 degree hinges which I glued on the face mask so that the beams can pivot and hold onto the face plate.

So the next step is to start getting the electronics of the helmet together. I'm using an arduino uno that I can program in the LEDs for the eyes and servos to open and close the mask. I ordered a pack of LED's, and arduino servos, and a pair of cheap shaded blue glasses off of amazon. My plan is to drill holes in the bottom of the eye sockets for two LED's per eye. Behind the eye socket will be the lenses from the glasses. As I am not very good at programming, I used the coding and wiring from here. The only problem I had was I had to turn the button 90 degrees of of what was said and have it jump over the center of the bread board. I chose the flickering light option off of the forum and this gave me a really cool result. I haven't done anything with the actual mask but I wired what I could into an old foam version of the mask piece. At this point i have not gotten the servos in the mail, so I am just using the LEDs right now. This is my first test of the lights. Next i need to get the servos, wire them up and make sure they work before putting them in the helmet. I also plan to solder all the wires to keep a solid connection.

AuthorMy name is Nathan and I enjoy building and creating things, weather it be out of wood, paper, or even on the computer. I want to start recording all of the fun things so this is where I am. Why Does this existI have recently started to play with Blender. A 3D modelling and design software. I have also built several costumes and helmets which I will be posting future ones up here. This site is mostly about that and other projects I might have.
If you're interested in this stuff...So I use a program called blender which is a great opensource modelling program. This allows you to model, and also animate and ever program games. Its a great program to use as there are endless possibilities.
http://www.blender.org Another useful site is for the helmets and such that I make. This is from a papercraft design program called Pepakura. It allows you to print out designs to build whatever you want. There are tons of tutorials online to see how to use it. http://www.tamasoft.co.jp/pepakura-en/ Archives
