instructable v2

I literally tried uploading my instructable multiple times to the website, and I am tired of losing everything I typed. So I'm putting it here for now.




Hello! I've made a costume of an "object head" character that has a stereo as a head, along with a launchpad to make music along with it.
Mask materials
-EVA/Craft foam
-Goatskin Leather (which can be found in your local hobby lobby, in the leatherworking section)
-Cardboard
-Gorilla Glue
-Tape
-Nails
-A bike helmet
-Mesh fabric
Launchpad Materials
-X M3 10mm Screws
STEP 1: BUILDING THE BASE


I cut out a small rectangle of cardboard and nailed it to the top of the helmet. It should be fairly easily to drill the nails into the helmet because I bought a plastic helmet. I secured the nails with gorilla glue just to be extra safe.
For other safety reasons, just make sure your nails are short enough so that they don't protrude out the other end of your helmet.
But afterwards, this cardboard piece should function as a "flat surface" to build upon as a base.
STEP 2: BUILDING THE OUTER SHELL


I cut out 1 inch cubes of foam and glued them onto the cardboard surface, one for each corner.
Afterwards you want to make measurements so you know how big you want your stereohead to be. For me, I wanted mine to be just a little bit bigger than my head, so I measured fairly close to my head, but gave myself enough wiggle and breathing room. I also measured about a half inch lower than my jaw so my entire face will surely be covered.
The two measurements I got were 9x13 inches (top, front, back) and 13x14 inches (sides). But of course, measurements will vary based on headsize.
Don't forget to cut out a space in the front piece of the shell so you can see out of.
I used gorilla glue to secure the top of the shell down onto the foam. After it dried I connected the other parts of the shell with tape. Make sure the tape is sturdy enough, I would recommend something like duct tape so it won't peel off as easily as masking tape, for example.
Afterwards, I used goatskin and covered the mask with it. I cut out foam squares in the same measurements and wrapped and glued the goatskin to it, then glued that onto the cardboard shell. However, this proved to be very tedious (but I had no choice since I had limited amount of goatskin). If you can get a roll of goatskin large enough, I would recommend covering the shell in one-go.
I used other pieces of leather to cover the edges of the mask to make it look more finished, and to also cover any cardboard that was peeking through.
STEP 3: LAUNCHPAD
I followed a video tutorial for the launchpad.
You can find it here.
I ended up with something like this.
STEP 4: FINISH
That should be it though!
As for making the launchpad mobile, I found a lot of difficulty due to the type of phone I had. I had a google pixal which didn't have a lot of good mobile launchpad/midi apps that were interesting or worked well with a handmade launchpad (most were for official launchpads).
I found garageband worked the best, so if you can get your hands on an iphone or ipad I would recommend that.
But overall you should have a pretty fun musically themed costume.

you never want to connect power directly to the ground
there should always be a 'load' on the circuit
