Arduino-controlled, Aluminum Archangel Costume Wings

I have always loved the Marvel character Archangel. When my brother, (Shameless plug alert) budding comic book artist David Fernandez, showed me pics of a cosplay convention he went to I thought “wouldn’t it be awesome if someone made life-size archangel wings?”.

The idea sank into the depths of my mind and had a death grip on my brain. I searched around to see if anyone had attempted it before and all I found were a few guys that made wings out of cardboard, while some went far enough to use aluminum foil. Someone had to do justice to the character! Someone had to MAKE IT REAL! So, I took it upon myself to do so.
Arduino-controlled Wings
In order to make them to scale but not too heavy to move around, I made them from 7075 aircraft grade aluminum sheets that were 1/32″ thin. I have to say, that stuff is awesome. It’s a bit pricey, but so strong and resistant to deformation is unbelievable.

I didnt want the wings to just be static or flop around on my back, so I decided to add in some gizmos to make them move. I wired up some gloves with push-button switches in the fingertips that controlled 4 continuous rotation servos which would in turn wind up a high strength fishing line to pull the wings closed. To open them back again, the wing panels were connected with spring hinges.

This is my first Instructable, so please forgive me if I dont have super detailed photos of every step. If anything is unclear just ask. Also, I’m pretty new to the maker scene so these wings were built entirely at my home where I have no shop or the tools found therein, just a dremel and a basic power drill. In hindsight, there are at least 972 things I’d do differently if I could go back. I dont claim that anything here is the best way to do it, its just the way I did it. With that said, I’d love to hear what you all think! As there are a lot of details in this project, I’ll assume for this instructable that I dont need to be super explicit about things like stripping wires, soldering, connecting the arduino to a computer, etc.

More documentation and photos of the actual build process can be found here on my blog:

Finally, here’s a video of them working. This was taken before they got the last bit of polish and detailing they have in the photo above.

Step 1: Materials

With a few exceptions, most of this stuff is pretty run of the mill Home Depot faire. Although I don’t think anyone would actually try to recreate these (you’d have to be as crazy about the project as I was and I was probably certifiable), I tried to be as complete as I could be, sparing a few details, on the materials list. There are comments throughout, so feel free to just skim it or read in depth if you’re curious.

Arduino – used an Arduino Uno for prototyping and getting everything dialed in, then I moved it over to the Arduino Pro Mini to make it all sexypants.
Breadboard for prototyping
Perfboard for making it more permanent
Soldering Iron
Resistors – 8 x 10K ohm
Toggle switch
Thin gauge wire – In many instances I used very thin gauge enameled magnet wire. Do NOT do this. I was seduced by how low profile it was and foolishly ignored how easily it fatigues and breaks. Save yourself a lot of headache and get some nice thin, stranded 26+ gauge wire for all of the applications in this project.
Wire strippers
Wire cutters
Generic “Project Enclosure” box from radio shack
4 x AA battery holder from radio shack
Continuous Rotation Servos – I used these, the largest ones SparkFun had to offer because they were easy to get and had a decent amount of torque.
JST Jumper wire assemblies – I used four 3 wire jumpers and 2 5 wire jumpers like these.
Breakaway headers – Straight and 90 degree

Aluminum sheet – Like I said, I used aircraft grade 7075 aluminum I got from Despite having a 10+ ft wing span, the wings way under 20 lbs. I dont think they would have been as light and durable with regular 6061 aluminum. It took me about four 3ft x 4ft sheets of the metal.
Aluminum L channel – About 6 feet or so to use as support to keep certain wing panels from flexing.
Dremel rotary tool – Dont get the cordless one. It runs out of juice in minutes there is a LOT of cutting to do. I tried using other tools like a nibbler (shears designed to minimize distortion when you cut), but the 7075 Aluminum is just too damn hard.
Fiber-reinforced cutting wheels for Dremel – The 7075 Aluminum eats through cutting wheels like you’re cutting with kraft singles, other cutting wheels would be useless. Maybe the dremel metal wheel would have been better or a band saw, but I dont know how those things handle metals, particularly hard 7075. Feel free to comment if you know.
Diamond tipped bit for Dremel – I used it to etch the patterns in the wings. It… took… forever. I wouldnt wish it on anyone, but the effect afterwards was worth it.
Spring Hinges – I used ones I bought from McMaster-Carr. It was tricky to get the ones that were strong enough. In the end I think I could have gone with bigger stronger springs, but those would have probably begged for stronger servos too which get very pricey very fast. Go to their site and search for 1613A4 to get the same ones I used.
Regular springs – got a few at Home Depot, I think they were somewhere around 3-4 pounds of pull force
Power Drill
Drill Bits – assorted sizes
Sand Paper  and sponge mop – 100 grit paper puts a really nice brushed finish in the aluminum. You can wrap the sandpaper around a sponge mop and brush the aluminum sheets while on the floor to get nice, long, even strokes that leave a great brushed finish.
Sanding sponge – It helps to do some of the finer work without the sponge mop
Aluminum Backplate with Harness – Scuba divers use them to attach air tanks to their backs, this is what the wings actually attach to. I bought one from eBay (just search “aluminum backplate harness”) for cheaper than they’re usually found, but here‘s an example of another you could use.
High strength fishing line – I bought 50 lb test. I dont think there is anywhere near that much force on the line but its always nice to eliminate room for failure. To be honest, the knot you tie might have more of an effect on the project than the line you use.
Hot Glue Gun – A true godsend
Miscellaneous Fastening Hardware – By the end, I made about a dozen runs to home depot to get the right hardware to hold it all together. Sadly I didn’t document the sizes of all my hardware, but if I recall correctly, its something like 50+ #4 philips head nuts and bolts (1/2″ long), 12-15 # 6 nuts and bolts (1 1/2″ long) and 4 eye screws with nuts and loads of #4 split lock washers.
Pencils, sharpies, rulers, scissors, etc…
Safety glasses and Ear plugs – Cutting sheet metal with a rotary tool can get a little loud and debris may fly

Scanner and Projector – These aren’t really critical, but I used these to blow up the small scale model wings I made up to the full 12 foot wingspan patterns. I’m sure there are other ways.
Photo Reference – I used an amazing statue made by artist Mark Newman for Bowen Designs as a reference (photo posted in Step 2). However, I couldn’t get my hands on one so I had to eyeball the wings, make a scale paper model of them then blow it up to actual size. I couldn’t make them 100% to scale or I wouldn’t have been able to move or walk in them.
Large pieces of cardboard/butcher paper – These were helpful for making templates of the wing shapes to use later on.

Step 2: Shaping the wings

Note: I’m having a little trouble locating some of the photos I took while making the wings, so I’ll post more as I get them.

As a photo reference, I used a statue of Marvel’s Archangel created by Mark Newman for Bowen Designs. I could go on and on about how great the statue is, but suffice it to say that it was no small part of my inspiration. Again, the wings I made are not 100% to scale with the statue since they would be too big for me to walk or even move with them on. The wings are actually in six panels, each of which had to be cut out of aluminum: The main wings that have an inner and outer panel on each side and the two secondary wings.
Schematic Arduino-controlled Wings
Since I couldn’t get any measurements off the statue itself I had to improvise. I created a scale model out of cardstock which allowed me to add/remove material easily to get just the right shape. Unfortunately, I’ve since lost the model and didnt take any photos of it 🙁

Once you have the right proportions in your paper model, use a scanner to get a digital copy of the wings and use a projector to blow up the image onto a wall or floor. From there you can increase or decrease the image size until the wings are the correct size. I aimed to have each wing be six feet long from base to tip. Using a large piece of butcher paper or cardboard, trace out the shape of the image. Alternatively, you could just project the image onto the aluminum sheets, but I found it helpful to have a paper template I could move around and roll up easily.

Step 3: Cutting the wings

I first traced out the paper templates onto the aluminum sheets. I carefully positioned the paper over the sheets I had to make sure I got the most out of the 4 pieces of Aluminum I had. The secondary wings and the inner panels of the main wings were one solid piece but the large outer main wing panel had to be made from two pieces.

Use the dremel with the fiber reinforced cutting wheels to carefully cut along the patterns on the aluminum. There is a lot of cutting to do, so use safety glasses and earplugs to reduce the wear and tear on your eyes and ears.

Once the wings are cut, wrap the sandpaper around the sanding sponge and go along the edges of the aluminum to remove any burr and make it nice and dull. The wings will have a pretty wide wingspan so you could hurt a lot of people if the edges are sharp.
