    So I wanted to show my WIP Mk42 helmet. This was helmet was originally Gimpee's pep file and I converted it so it was 3d printable. Ive been working on it for about a month now and hopefully will have it ready for Chicago Comic Con. Its going to have a motorized faceplate, neopixel strip eyes with working replusor and arc reactor. Oh it's going to have one other little thing...voice recognition!. So I should have a very interactive helmet with a HUD (an lcd in the faceplate) and talking Jarvis. I got the voice recognition chip today and can it's going to be a pain to program but the results will be oh so worth it!. Heres what I have so far! Enjoy

    So to add to the fun of this small project, I'm adding a muscle sensor to the project. I'm going to add this to arm, false readings shouldn't be a problem as I long as I code it correctly. This way, when I lift my arm and flex my bicep it should light the replusor up.

    Looking good! What are you going to use to control everything?

    To handle everything I'm going to use an Arduino, more specifically a Adafruit Pro trinket 5v/16Mhz. The Pro trinket should in theory have enough for I/O connections, if it doesn't I'll have to switch to the Mega 2560.

    Subscribed! This looks like a sweet thread. Are you planning on doing the voice recognition through a microphone?

    Yeah...the equipment already has the mic built in. The mic is going to be put into the jaw and not be seen (hopefully) along with the chip so that way it picks up the commands easier.

    Been playing around with the code guys and here's what I got so far..if you watch the lcd, you can tell i got some debugging to do. Other that than that this J.A.R.V.I.S now has a voice and screen feedback

    nice work! I actually live in central MO. As far as voice recognition goes, I'm going to hold that one close to the chest until I get it totally done. So that I can release all my code and list of materials i've been working with. I know that frustrating, but I want to do it that so that way the bumps are ironed out and if somebody wants to replicate it, they can. I'm also thinking about making my own custom voice recognition pcb's with lights and servos so that I can sell them at way cheaper than if you were to buy it separate. This way, anybody who wants J.A.R.V.I.S in a pep or 3d helmet, they can add it no problem. Here's what I have so far done yesterday. I will say that doing dual servos in the helmet was kind of a monster lol

    Heres the voice activated faceplate:

    understandable...

    I think they make 'dual arm' servos..

    (saw a picture of one just recently)

    Ok some news updates since I haven't posted in a little over a week. It looks like I won't be going to the Chicago Comic Con :cry but I am still going to get this helmet finished within the next few months. I have been playing with things and looking around on the interwebs at cool things to do to this helmet electronically. Well I happen to stumble over something super awesome but I'm going to have to do some modifications if I want to make it fit inside the helmet along with my big melon lol. So I got to looking around and I found that a kid's toy more specifically the Mindflex toy made by Mattel is actually an EEG device. (No idea what that is? I had no idea at first but let me tell you) It is a chip that records the electrical activity of your brain. Well I got to looking some more and you can actually hack into this toy with about 3 wires to an arduino to see this activity. You can then write a program so that whenever a specific brainwave meets a predetermined threshold, it does an action like move a servo. So essentially you can control servos, lights and other gadgets with you mind. I am going to implement this into this helmet so that I can control the opening and closing of the faceplate with my mind. BTW if you wanted to do this at home, I bought 2 of these Mindflex toys off of good ol' ebay for about $30. It took less than 10 minutes of soldering and then I could see my brainwaves on my computer. So needless to say, this project just took off as far as electronics go. I'm going to try to get some more pictures and videos up by this weekend of everything I've done so far and a list of everything I've used to this point (its a pretty big list)
    Also I'm going to try to get the code uploaded to this point so that way if anybody wants to replicate it they can. I just have to figure out Github.


    The site(s) I have been using to do this EEG are:

    That is so cool, dude. I'm looking forward to seeing your progress! I might just have to try this out for myself if your's turns out pretty well. Good luck!

    Thanks!

    One a side note---> here's my flickr link for my pics. It's easier to upload straight to there as opposed to here. http://www.flickr.com/photos/104495276@N07/sets/72157653419499803 Also I started laying down some red yesterday and should have it painted red by the end of the weekend. As far the gold goes, I'm unsure because I used that Sunburst gold like everyone has, and I don't really like how it comes out of the can. So I''m going to do a little more research into that this week.

    Ps, If you look at my other flickr album, you can see another very cool Ironman project I designed.

    Finally got off my butt and started to lay down some more paint this week. Got to finish the cheek pieces and add the details in the face plate and then off to adding the electronics into it...maybe I might get most of it done by the end of next week (hopefully)

    I also got around to figuring what this Fritzing program is and its pretty awesome for setting up virtual breadboards. Heres the mess I mean "system" I've got laid out so far. This diagram is not 100% but more like 90% because I changed a few things since I made this but here it is. Plus there's a few wires that are listed because Fritzing doesn't have them loaded like for example the I2C interface on the LCD module.

    That mind control hack thing, does the arduino has to be attached to the sensor unit?
    Or can you run a wire and move it someplace else?
    For example, sticking it in the chest piece, where there's much more room for the battery pack and the CPU.

    Edit:
    Cuz I was thinking about doing some things you mentioned in your build(A muscle sensor for the repulsor arm), but there are other commands I'd like to be able to send to the suit too, without needing to add external buttons(Like XRobots' iron man suit).
    While we're on the subject, how accurate is the hardware?
    Will it be able to differentiate between several commands, or limited to like 1 or 2?

    When you get the mindflex wired up, your going have a TX and RX wire for the arduino coming from the headset and you would plug them into PINS 0 and 1. the arduino can then be programmed to have your thoughts controls whatever you want. Sorry I forgot to mention I didnt have time to wire that in.

    So you used the board but didn't put it in the build?

    How many commands could you process through it?

    I forgot to add a description for that black module in the diagram. That is actually the voice recognition module I'm using. The Mindflex chip isn't in the diagram but will be added later due me changing my mind about my helmet and redesigning it. I've redesigned my helmet to add a moving jaw and more movie accurate details. I'm gonna have another update in a few weeks.

    Yeah your going to have a TX/RX/GND wire all coming from the mindflex. The Mindflex does have a built in bluetooth module in it but I couldn't find to hack that. As far as commands, it's really only one or two but that would be good enough to open or close the faceplate.

    Looks like you're using the EasyVR?
    Been working on the same thing myself, but unfortunately it's very very particular about the voice input. Been having problems with it recognizing my voice to be honest.
    What software did you use with it?

    I haven't been having any issues using the factory software with it. You can adjust the "strictness" of the recognition settings.

    What up everybody? So I've been redesigning my Mark 42 helmet to add in the brainwave sensor so I can open and close the faceplate with my thoughts. Sorry I haven't been posting with regular updates - life's hectic lol going to school, stay at home dad and I'm getting married next month so yeah lol Well I've gutted the original mindflex toy and scrapped everything but the neurosky chip (this is the chip that reads the brainwaves and everything else in the toy is junk) and made a custom chip to hold a battery pack, the neurosky chip and a bluetooth module. I plan on putting it in a replica headset Tony Stark uses in IM3. Thats what this chip is currently in right now (a mock up headset piece right now). So yeah this is what I've got going so far with the redesign along with the new helmet.

    P.S. Excuse my 3d printed part quality, my printer is on the fritz...

    Hey everybody, just thought I'd give a quick status update.----> So I've went through a few iterations of the headset to find one that actually fits all the electronics and still looks the part. Well it's almost finished. I should hopefully have pics posted up by tomorrow night or Monday. The servo moves with no problem being powered my brainwaves. As for the helmet, I've had a few setbacks, the new helmet has cracked due to falling off work desk. I've a got a Mark VII work in progress I might put it in, I've even thought about going about and putting in a Mark 45 or even the new Mark 46. I haven't made my mind up just yet.

    Great persistence mate. Hopefully soon I'll be learning some of this coding stuff to put in mine.

    Well done.
