Synth Glove

No, it doesn't make sounds - it's an LED Vader-San Synth glove!

So, what is a "Vader-San Synth glove"?
Well... It's a Fursuit, to put it frankly, which is based on a species made by an artist called Vader-San.
Their unique mixture of robotic features and softness, the glowing screens and expressive LED eyes, as well as the potential to add unreasonable amounts of LEDs to them, it all just tempted me too much!

The ultimate goal of this project is to build the entire Fursuit, from head to toe, but for now, we'll be keeping it to a partial set of arms and maybe a head.

And what's it supposed to do?
Well, glow of course! Not just any glow - well-coordinated, complex animated sequences of LEDs synched to music, using custom STM32 boards across the suit to generate patterns, with offline voice recognition running on a Raspberry Pi and a whole host of DIY this and that to stitch everything together.
Sounds crazy, right? Good. That's what makes these projects interesting!

So, you're interested in this and wanna look into more details, huh?
Well, let me introduce this project to you!

Update: Small demo for the current status of the project on my twitter page!

The gist of 'er

This project is a pretty large one because of the complexity of everything, so I'll give a rough outline of the different components that interact and what they do, and what I still want to do with them.

First things first, how's the whole thing look? Pictures are always better than words I'd say, so have an example:

Yep, wow, OK, there's a bunch going on already. Let's break it down:

  • We have the foam construction. Right now, we're planning on using EVA Foam sheets to construct most of the suit, with maybe a few other materials like sown fabric here and there. This is one of the parts where I'm still learning a lot, but it's quite fun!
  • The head is up next for construction - it will feature an easy to 3D print base frame that will hold a 32x64 LED Matrix for eyes behind a tinted plastic visor. It'll be covered in EVA Foam and painted and sanded to provide a hopefully smooth look. Oh yeah, and a servo motor actuated jaw :P
  • The LEDs themselves. They're mostly WS2813's (the version that has a backup data line, which can save your butt a LOT), with a few side-mounted variants on the PCB itself. LED control is pretty advanced right now, but wiring the LEDs in a reliable and easy to repair manner is still something I'm learning.
  • The "SuitBit" controller PCB. This is the PCB you can see on the hand, right below the glowing ring of sorts. It's a STM32L4 based board, meant as a "animation slave" - the later suit will have four, maybe up to eight of these boards, working together to provide full 60 FPS even with complex effects, with each board driving a separate string of LEDs.
  • Communication between all the elements is handled via a custom protocol called "FurComs". It uses CAN-Bus hardware for multi-master, differential communication, but allows for messages of up to 255 bytes of length, considerably more than CAN.
  • The "SuitCore" PCB - this one... Does not exist yet. The plan is to create essentially an overpowered Raspberry Pi shield, providing 20A 5V output to drive LEDs and other components, a bit of battery management for LiFePo packs, a hopefully beefy I2S Audio Amplifier for output, and a HUB75-Compatible LED matrix output. 
    It will be responsible for keeping everything in sync, communicating, providing power... Everything, basically.
  • And the Ruby-Side control code. It provides a flexible sequencing code that makes it easy to create animations and effects in sync with music and other sound snippets! 
    It also uses Pocketsphinx for offline voice-recognition, which will allow us to have full and easy control over the entirety of the suit's capabilities without needing to use awkward and slow button inputs.

Feel free to look through the project logs for each of these things, and leave some comments to ask about more specific details.

Also, see the linked GitHub repo - all of the necessary files and sourcecode will be on there, so you can easily see how we did some of the black magic~

The end goal

Pictures and images always speak more than just words, so I'll show you how it's supposed to look:

As you can see, a lot of the LED code is pretty much done!
We can draw arbitrary shapes over the LEDs, set their colour, and smoothly fade them in and out - we just need to construct more of them :P

The head will be interesting because of how we want to construct it - follow this project if you want to see more!

A few other things that we'll need to look into will be the tail, and whether or not we want to give it mechanized wagging abilities, or if we leave it dangling freely.
Along the tail and back will also be a servo-motor actuated mane, made from clear acrylic plates that will, hopefully (maybe) be able to stand up or move, to give this suit a bit of extra emotion.

What's up next:

    Oh, you thought this project was somewhere on hiatus, huh?
    That perhaps 'ol Xasin's been going away from his nerdy things? Not at all!

    The last few months have been... Weird. For me and for everyone, for sure.
    Apart from online University and having to be home a lot more than usual, I also started writing my Bachelor Thesis... So I haven't had as much creative energy to put into things like this.
    Don't worry, I will get back to this stuff when I have time, but I am realizing more that there's no rush, and right now there are other things to focus on.

    Remember that yourselves: Take time for the important things, like yourself :)

    Regardless, I have been making slow and steady progress on this whole thing.
    Apart from a few gorgeous demos on twitter, I also started working on the foam construction of actual wearable pieces, I've started talking with other makers in this field of expertise, and I also started making a 3D model for the head!

    That's the thing this project is going for next, by the way. Pretty 3D printable models~

    Right now it's a bit of a weird... Cheese-Grater kinda model, but I promise there's a plan :P
    Be patient, tag along, and you might see OpenSCAD, Blender and FreeCAD put to... Very creative use :>
