I haven't worked on this project since I moved, no. A lot of my electronics tools are still packed away, and I need to reinstall Octopi to manage my printer again. I just got a workbench last week that I can use for assembling projects (my old desk is being used as a sewing table for my wife's quilts), as well as another shelf that I'll be using to help get things unpacked. There's a lot of house projects that come with a move, and I've had some coding projects that have also taken my time and attention. That said, I'm not worried about it. It's normal for me to work on projects in bursts, where one project takes all my focus for a while before I either finish it or move on to a different project for a bit. The Iron Man arm has so many features that have to fit so closely together than it takes a lot of mental energy to design, so I don't want to be distracted by other projects when I'm working on it. For example, the latest version of the arm is still missing wrist rotation, a latch to hold it closed (magnets aren't good enough), stand offs for the outer shell, elbow hinges, articulated elbow armor connection points, and channels for the wiring. Combined with the 8 different rocket assemblies and hinges to open up the arm, it's a lot to cram into a tiny space. When I do start work again, I'm probably going to start with printing more prototype frames and fitting them to my arms, so I avoid accidentally making it too small to move in again.

@@zandermarriott I've been working on some programming projects, as well as doing some Blender tinkering, but nothing on the arms recently. Some parts of the project are straight forward - make the Blender file bigger on the inside so my arm can fit better. Other parts are more technical - like redesigning the rotating cuff, adding a latch system, and mounts for the external shell. It's annoying to switch between Fusion360 and Blender to try and make it work, so I might have to figure out a way to model and animate mechanical parts in Blender. When my current project (some 3D work for a friend) finishes I will probably start work on the arms again.

@@DrCyanide good to hear! This build is great and a lot of us are keeping up on the progress!

No, I won't. There's too much of it that has to be precise in order for everything to work, so the normal methods of scaling cosplay armor to fit simply won't work. After I have a fully finished version I might sell it, but right now that's too far away to consider.

@@DrCyanide i see. understandable but thank you for sharing the idea with us

I think you'd be interested in the later versions of the project (this video is about 3 years old, and there are two major revisions since it was posted). Each rocket can be individually controlled, and they pop out in a pattern. The two sides also open up and allow me to fit my arm in.

@@DrCyanide damn dude thats freaking awesome im sorry i didn't see how long ago it was . Could you build me a armor not ironman blood red and chrome crymson dynamo armor

@@bearvassar6690 I don't do commissions like that. For one thing, sizing armor is incredibly difficult, and I don't want to deal with the hassle of trying to get it to fit someone else. For another, large commissions eat into my personal time too much.

@@DrCyanide Thank you for responding is there someone else who can help me

I don't think I could bring anything new to the subject. The code boils down to "when you get a signal from the user, rotate one servo, wait, then rotate the next servo", and you can find lots of great tutorials and example code for each of those steps.

These motors are called Servos. They can only rotate 180°, but you send them a signal and they'll try to go to a specific spot in that 180°. Servo sizes are based off of weight in grams. I'm using 9g Servos, which are decently small and strong, as well as very cheap. To control them, an Arduino is recommended. There's lots of types of Arduino, each with their own special features, but I'm pretty sure all of them can control Servos. If you want to control a lot of Servos with one Arduino, you'll want to look into a 16-channel PWM controller too. As for 3D modeling, different programs have different strengths and weaknesses. Blender is good for making organic looking parts and artistic models, but it's harder to design mechanical pieces with it. Fusion 360 has a free license you can use, and is great for designing and modifying mechanical parts, but it's hard to use it for much beyond that. Currently, I'm using a mix of those two programs. As for learning the programs, I recommend watching a short getting started video to learn the basic controls, then trying to implement the ideas from the tutorial in a completely different way to make your own project. You'll probably need to skip around a bunch, and make a bunch of mistakes, but you'll learn with practice

@@DrCyanide Thank you very much man, keep the up with the videos these are really cool.

@@DrCyanide Also do you got specific fusion 360 tutorial you reccomend to make mecanism parts?

@@slendy7746 Not really. Just make sure to use constraints and assign variables for values you use frequently.

@@DrCyanide ok thanks for the advice

All the rockets angle outwards, so as long as they flew straight (and you didn't push your wrist down as far as you can) you'd be fine

The goal is to build a whole suit, starting with the most intricate parts first. After the arms I'll either work on the helmet or the shoulder rockets, depending on what I'm feeling at the time. Because I'm doing the hardest parts first, I think the project will pick up speed as I start working on easier and easier parts.

Not the current design. The way I modeled things in Fusion 360 the model is prone to breaking (the files are currently broken), and not set up to scale to fit others well. I'm working on a new version that should scale better and has the outer shell, but it's not finished yet. I'm still unsure if I would sell the new design. If I do, it would likely require customization for each order to fit the user, which means it would take time to get and be rather expensive. TL;DR: I'm not selling files now. I might customize files/prints to fit in the future, but IDK when that would be or how much it would cost

@@DrCyanide Thanx for answering, i will see how evolve this project ^^

I'd be up for discussing it, but considering how different this project is from anything else listed on Do3D (can't just resize it and have it work, requires electronics, etc) I'm not super hopeful that it would work out

Right now I do not plan on making it actually fire, just for use at conventions and similar events. That said, it might be possible to modify it to fire. If it were modified, the ammunition would likely be bottle rockets. I'd expect the accuracy to be miserable - due to a lack of stabilization on the rocket and the high probability that the rocket mounts would twist while firing. The lids/covers for the rockets (not in this video, still designing them) would also direct all of the heat from the rockets inwards towards the wearer's arm and the electronics. So I'd give it 50/50 odds on being able to pull off a cool action shot one time if the 3D printed version was modified, and a 65% chance of pulling off cool action shots multiple times if the design was manufactured out of more temperature resistant material.

@@DrCyanide there is another solution. Rockets can be used as flares, Spark balls like Captain intrigue from superhero Armory or Airsoft grenade launcher tag shell look that up Captain intrigue or the airsoft. Either way you can have one of those qualities for launching your rockets. As for your laser it look rattle and loose on your wrist you think you can tie it up a bit? Speaking of airsoft. Do you think you can build a I Hidden shoulder marbles, pallets or whatever those things are on the Iron Man Second battle of the terrorist? If not build Iron Patriot Shoulder Chain Gun. For some good reason is awesome! 🤖

Sadly no, for a few reasons. 1) Fusion 360 really hates the way I design things, and several parts of the file broke part way through designing it. I'd rather spend my design time making a better version than trying to fix this one. 2) Because the Fusion 360 files are so prone to breaking it's impossible to scale the current version to fit anyone else. My next version is going to be a combination of Fusion 360 mechanical parts and Blender to position them. I'm hoping that combination will let me resize the arm for others.

Alex's Iron Man project is awesome! I don't think he'd have the time to contribute to this one - plus it would be challenging to work together on the same project due to the distances between us (shipping parts world be a pain)

@@DrCyanide then perhaps use zoom, or Skype. And maybe you could help with the end design!!

I'm glad! It takes me a long time to make update videos, but I do it in hopes that it can inspire others. 🥲

I recorded the footage for an update video, then stuff got in the way of editing it, then I made a bunch more progress - So much progress that I need to re-record! I'm eager to show it on UA-cam, because the arm looks very different now.

I've got several smaller updates on my Tiktok account (www.tiktok.com/@drcyanide1). I have lights working under the rockets, some sound tests, a way to rotate my wrist, and some progress on wrist lasers. I want to do some more design work with the lasers before doing another UA-cam update. The small video format of Tiktok (with less editing) just fits incremental updates a lot better for me. Thanks for checking in!

@@DrCyanide Are you on Instagram. I don't have Tic-tok. I had suggested in my Facebook group suggestions of a once a week or once a month video round table. This would integrate like minded minds who are working on although different but similar exoskeletal projects. I was considering 5 people, you are one of the aforementioned people. This would introduce one another to suggestions, troubleshooting, techniques ect. Idea's that perhaps one of us haven't considered beforehand.

@@georgemurdoch1991 It's a cool idea, but I generally avoid Facebook, logging in only a few times a year. I am on the Frankly Built Discord server, and they also cover a lot of what goes into making suits.

@@DrCyanide No worries brother. All the best...

I use Fusion360 to model the parts, then Cura to prepare it for my 3D printer. For the code that runs the arm I wrote that myself in the Arduino IDE. All of those programs are free to use, but Fusion 360 kinda hides how to sign up for the free version.

I think it would have been was pretty close. Trying on the warped helmet it is a tight fit left to right. The faceplate warped in a way that makes it look a lot wider than it would have been.

@@DrCyanide USE THE SCALE FUNCTION IN CURA LEFT TO RIGHT IT WILL GIVE YOUR SIZE IF YOU MEASURE EAR TO EAR

@@fkingride.5500 I'm aware of how to scale things in Cura. I scaled the helmet before I printed it. At the time stamp you indicated it looks poorly scaled because it warped in the hot sun, not because of any issue with scaling or printing.

I make slow progress, so a slowly expanding audience is understandable. There have been a lot of new subscribers in the last few weeks though, so the channel is growing!

I'l try and share the video to keep it growing

While it might be possible to make that, the issue you run into is the servo's torque. The plan is that the doors that cover the smaller rockets will be held down with springs and opened by the servo that raises the rockets. The main rocket can barely lift itself, and will need a separate servo to open it's door. Based on that, I'm guessing that one servo wouldn't have the power to move all of the small rockets. On the plus side, having each rocket on it's own servo means I can adjust the opening/closing timing a lot easier, or open each one individually.

In the newest version (Update #8), the mini rockets are based on the dimensions of the 1/4A and 1/2A hobby rocket engines I found listed on a particular website. Those hobby rockets could theoretically launch out of the new design if ignited. I'm not 100% sure those dimensions are accurate, but the entire design is modular enough that I could update the parts if I wanted to try it. That said, this is intended just for show. I might do a "Make it Real" version after I get everything working, but I have enough features to pack into a small space as is that I'm not going to worry about that now.

Thanks! I'm aware of a few other attempts to make this style of rocket launcher, but I think I can safely say I've managed to cram more into the space around the arm than earlier attempts. Still a lot to figure out and squeeze in, but this was a big confidence booster.

@@DrCyanide 👌🏻😉
