Spooktastic Halloween Costume Projects - part 2

Halloween is just around the corner, and what better way to make your costume extra scary than to add some wearable Raspberry Pi tech to it? Walk this way and let's begin...

NeoPixel Sans Undertale Eyes

Still images don’t really do it justice, but the effect in real life is excellent

This full-on cosplay by Mel Ridler has an electronic secret – simple LED lights for eyes that can change into flashing circles of doom. For those that know of the game Undertale, the light patterns represent how the character Sans looks when he unleashes his true power.

This simple build makes use of a Raspberry Pi Zero connected to a NeoPixel ring that is set behind some frosted acrylic. With the touch of a hidden pocket button, you can activate the eyes, turning them blue. Another press makes them flash yellow, and a final press turns them off.

Steampunk Tentacle Hat

Each tentacle is controller by servos that run on a sine wave pattern to make them move more ‘naturally’

Have you ever wanted to have tentacles growing out of your head? Probably not, we’d hope, but we can offer you the next best thing: a hat that makes it look like transdimensional tentacles are growing out of your head by Derek Woodroffe.

It’s actually quite an ingenious build, using several servos and plastic tentacle skeletons to make the stocking-based suckers wiggle and move freely on top of the hat. Some latex, sealant, and paint bits later and you have a very weird and kinda scary hat.

Disco Ball

The insides are made of chicken wire

For a costume that is essentially a series of LEDs, there is a lot going on here. It’s fully autonomous, playing a preprogrammed light display, and can connect to wireless LAN to ape the light show that the builder’s house is playing as well.

The frame is welded together specifically to fit maker Wolfie’s granddaughter; however, you can make it fit whomever you’d like if making it yourself. It uses some custom 3D-printed parts to keep a Raspberry Pi and some batteries in place – at the time of making, it would last several hours.

Iron Man Arc Reactor

More than just a box of scraps in a cave

Voice modification and LEDs are cool, but how about voice-controlled (and reactive!) LEDs? This fantastic project from the MATRIX Labs team turns a cheap Iron Man costume into a party piece that is sure to attract a few nerds.

The voice-controlled magic is handled by Snips.ai, a customisable piece of tech that allows you to create voice assistants that work under your control. You can set keywords, train it to make sure it understand your voice, and then hook it up to your MATRIX board.

The Jacket 2.0

The command-line interface is perfect as it looks like you’re an eighties hacker, and it uses less power

The cyberpunk aesthetic will probably never go away, especially now that it’s easier than ever to install electronics into clothes, a bit like ‘The Jacket’ that maker CoreDump likes to wear at Halloween.

It’s a pretty standard leather jacket, albeit with some serious modifications. Not just style bits like neon lights and punk spikes, but also the fully functional Raspberry Pi installed into one of the sleeves for that ‘hacking-on-the-go’ look. There’s also a hidden action camera in one of the spikes, perfect for first-person video fun.
