    Arduino brings Ghost Rider costume to life

    Reading Time: 2 minutes

    Long before Nicolas Cage ever portrayed the character on the silver screen, Ghost Rider appealed to an edgier subsect of Marvel’s audience. We won’t do a deep dive into the character(s) and their Faustian deals, but suffice it to say that Ghost Rider is a human man who turns into a flaming skeleton that rides a motorcycle. Where that lands on the cool to cringe scale depends on the particular appearance, but Andy’s Halloween costume recreation of Ghost Rider is definitely cool.

    Andy’s costume includes a skeleton mask and the appropriate biker-style leather jacket, but really comes to life thanks to the added effects. Those include LED lighting and billowing flames. Andy can activate those using a small handheld remote control. When he does, the LEDs illuminate pieces of red cloth that flap in a wind created by big blower fans. Those mimic the look of flames shooting out from the jacket.

    An Arduino Nano 33 BLE board controls the LEDs (a total of four red and two yellow), as well as the two blower fan motors through a TB6612FNG-based DC motor driver. Those blower fans use a lot of power, so this requires a large LiPo battery that sits in a backpack. The remote contains a second Nano 33 BLE powered by a small LiPo battery in a 3D-printed enclosure. The two Arduino boards communicate via BLE (Bluetooth Low Energy) and the remote control’s Arduino uses its onboard accelerometer to respond to motion controls.

  • Huge LED globe becomes Halloween helmet

    Huge LED globe becomes Halloween helmet

    Reading Time: 2 minutes

    Some Halloween costumes are creepy, others are racy, and a few, like this one, are just plain cool. LEDs have been common since the 1960s, but they can still stand out when done well. As it turns out, one way to achieve that is by arranging 378 of them around a big globe and wearing that globe on your head like Redditor HGRDOG14 did for Halloween this year.

    We’re hesitant to call this a “Halloween mask” because of its sheer size, but “enormous glowing Halloween helmet” doesn’t have the same ring to it. HGRDOG14’s creation started as a 24” beach ball. They then covered that in papier mâché to create a rigid shell and removed the original beach ball. After that, they covered the papier mâché sphere in strips of WS2812B individually addressable RGB LEDs. Those strips have 30cm spacing between LEDs and HGRDOG14 staggered each longitudinal strip in order to arrange the LEDs in the pattern you see.

    Every one of those 378 LEDs got a 3D-printed hexagonal cap to diffuse the light. An Arduino Nano controls all of the LEDs as a single strip with one data pin, though power comes from three separate battery packs that are necessary to handle the current at full brightness. A 16-button keypad lets HGRDOG14 switch between different animations and effects created using the FastLED library. 13 of those buttons correspond to different effects, while buttons 15 and 16 adjust the LED brightness (button 14 is unused).

    When turned on and running animations, this Globe Head is quite a thing. HGRDOG14 omitted two hexagons on the front for eye holes and there is a seam on the back, but otherwise it is an unbroken sphere of blinky LED goodness. It’s great for Halloween, but is also perfect for EDM concerts the rest of the year. You can see it in action here.

  • Scale up your dragon costume with wings that extend, flap and retract

    Scale up your dragon costume with wings that extend, flap and retract

    Reading Time: 2 minutes

    Arduino Team — November 1st, 2021

    This year for Halloween, Quint BUILDs wanted to make something special for his daughter’s costume. Quint’s idea was to design and fabricate a pair of mechatronic dragon wings that can mount to a user’s back and move in three different modes by utilizing a set of pneumatic air cylinders. 

    The prototype began as a single air cylinder connected to a relay that was, in turn, controlled by a single Arduino Micro and button. This way, Quint could finely tune the timings and pressures required for the device. After 3D printing a simple controller, machining a few aluminum plates, and welding it all together into a second prototype, it was time to experiment with programming more complex movements. 

    Three pneumatic cylinders were used to create a couple axes of motion. First, the larger base cylinder moves a central piston vertically, thus extending and retracting them outwards. Each wing can flap independently through the use of two smaller pistons and linkages. Finally, pressurized air is provided by a compressed CO2 canister. These actuators are each controlled by a dedicated relay module that’s connected to an Arduino Uno.

    Whenever one of the three buttons on the controller are pressed, a subroutine for the specified movement is executed. This could include fluttering the wings a couple of times, extending them outwards, and even performing a more complicated flapping motion. 

    To see how this project was built in more detail, you can check out Quint’s write-up here on Instructables.

    Dad-daughter MechWarrior suit ready for trick-or-treating

    Arduino Team — October 31st, 2018

    The idea of a mechanized walking suit to carry you around seems like a great idea, but having a practical leg assembly for it is still a futuristic concept. As seen here however, if you’re still a kid, you might be able to get your dad to carry you around in a custom suit fashioned after a MechWarrior vehicle.

    The suit is beautifully designed by creator Gridlock Cosplay, and features an Arduino-powered control system. This allows the little pilot to command the mech’s human “engine” via a joystick and system of lights. The suit also features exterior and interior lights, a pilot cooling fan, spinning “radar” assembly, retractable pilot cage, and of course a cell phone holder in the padded engine compartment.

  • Dragon Ball Z head-mounted Scouter computer replica

    Dragon Ball Z head-mounted Scouter computer replica

    Arduino Team — October 26th, 2018

    Those familiar with the Dragon Ball Z franchise will recognize the head-mounted Scouter computer often seen adorning character faces. As part of his Goku costume, Marcin Poblocki made an impressive replica, featuring a see-through lens that shows the “strength” of the person he’s looking at, based on a distance measurement taken using a VL53L0X sensor. 

    An Arduino Nano provides processing power for the headset, and light from a small OLED display is reflected on the lens for AR-style viewing.

    It’s not exactly perfect copy but it’s actually working device. Inspired by Google virtual glasses I made virtual distance sensor.

    I used Arduino Nano, OLED screen and laser distance sensor. Laser sensor takes readings (not calibrated yet) and displays number on OLED screen. Perspex mirror reflects the image (45 degrees) to the the lens (used from cheap Google Cardboard virtual glasses) and then it’s projected on clear Perspex screen.

    So you will still see everything but in the clear Perspex you will also see distance to the object you looking at. On OLED screen I typed ‘Power’ instead distance because that’s what this device suppose to measure in DBZ. 😀

    Print files as well as code and the circuit diagram needed to hook this head-mounted device up are available on Thingiverse. For those that don’t have a DBZ costume in their immediate future, the concept could be expanded to a wide variety of other sci-fi and real world applications.
