Iron man motorised faceplate electronics tutorial!!!

[xl97]

I believe he uses accelerometer and not tilt sensors.. (if thats what your saying?)

accelerometers for the leg/walking trigger/project.. as well as for the faceplate project... I believe he does for his repulsors too..


for his eye circuits and new element arc reactor.. he uses photoresistors as the 'trigger'..

 

[Mdonci]

depends.. on which acceleromater you want to use..

which format/protocol it uses....etc..


then you test for a 'sweet' spot.... depending on the motion you desired to trigger the audio file to play/led to light/servo to move..etc.. (whatever it is you want to do)

I 'know' TheRealStark (Ryan) a bit.. and do not want to copy or rip of his idea/IP/project verbatim...

if we can come up with something 'new/different' enough and hes ok with it.. I wouldnt mind continuing on with some open source/community project stuff... (should be changed to community project IM thread or start new....etc)



(side note: I always wanted to do a 2-part repulsor where the ramp-up sound and fire sound were separate.. and triggered by two different events)

I don't really think that making somtehing that gives you almost the same as he did is not copying. He had a great idea, but I think that everyone who is a bit familiar with electronic stuff can figure out how the real Iron Man would work...

 

[xl97]

hi..

and thats your choice..

"I" just prefer not to copy him 'verbatim' (so to speak)..

using an accelerometer.. is not really 'new'.. but using it to 'flip' the faceplate up is more or less his 'idea'.... IMHO..

Im not saying nobody should bust out some code for it.. Im saying "I" wont be doing that (copying him verbatim.. just out of respect)..

I also think his are separate hardware.. (and not just one unit)

eye circuit is its own arduino/stand alone
face plate servo's/audio/accelerometer is another arduino/piece of hardware..

Ok I'm gonna have to jump right in now. This is the part everyone keeps asking me about via PM and I really don't have the time to trial and error or learn right now.

My project consists of:
5v arduino pro mini (same as UNO, but smaller) (http://bit.ly/X2MF5T),
2x5v micro servos (http://bit.ly/X2MUOC),
2 crappy LED's, both coming from pin 5 to gnd (http://bit.ly/W1RziA),

My question is: Can I just buy 2 of these:
http://bit.ly/T1MZ1u

Then put 4xAA rechargeable batteries (1.5v each).
Hook them direct to servos and direct to arduino?

As simple an answer as possible please guys. What's the worst that can happen? and if this will work which ports do I connect it on the arduino?

If that is wrong can somebody just suggest EXACTLY which battery pack and EXACTLY where to hook it up on arduino, and provide examples via UK eBay.

The person the provides this information will have completed this project and we will have given all our watchers the entire tutorial of how to motorise the lids from start to finish.

Like I said, I want to hand this to people on a plate, I wanted it to be as simple as possible for watchers. The thread has become increasingly more complicated over time. Lets get the basics 100% complete, I'll update the first post, credit where credit is due, then we can move on to the complicated stuff.

Please excuse me rushing but there have been so many ifs and variables along the way, my brain has virtually exploded.

Hi, the servos need a separate power source! The LEDs gonna work! And I think you need more then 6v to keep the Arduino optimal running!

Right now I'm at work, gonna check back later to give you more info!
You can check out my post from yesterday how I did the helmet! It's under "Iron Man extreme"!

Andy

 

[xl97]

IMHO.. there isnt a 'one answer fits all' solution here.

1.) depends on your Arduino board of choice
2.) depends on your servo of choice
3.) depends on your leds of chocie
..etc..etc..

*I think there is alot of info out there that may help/has been done already.

Andy W.-

why do you suggest the servo's NEED a separate power source (for a quick test?)? (curious)

I have personally driven the servo's from my Arduino.... and many tutorials also outline the same. (mine was under no load..worked fine)

I do NOT know the current draw/need of the servo of choice.. but if its under what the Arduino pin can supply..whats the problem?


*leds should have correct/calculated resistors for them

If under load.. the servos should be driven by battery pack (same as Arduino or dedicated) when in REAL use/under load..

but for a quick test of 1 servo.. you can probably direct connect to Arduino..

Xi97 the start of your post was offensive, telling me I intend to take credit for others work?! I've done pretty much 90% of the work and research before even posting here, then listed it in the first post for the 15,000+ views this thread has had. All Im asking for is the power supply and have said i will give credit in the first post to whoever provides it, not take credit! My name is not stamped anywhere, my name is not really 7sinzz, it's an anonymous screen name that has zero value to my reputation in the world. It carries no significance to me, I just want to provide and inspire help.

Im NOT here to obtain a fan base, im here to provide information that more knowledgable people have failed or refused to do! Assumingly Out of laziness or selfishness! That's all. Your modified codes have been included in the first post separately.

I've listed the exact components and links which explain everything about those specific components. The crappy LEDs stats are in the link. As are the servo stats. Once this tutorial is complete people can buy the EXACT products I have listed.

With reference to the AA housings I mentioned, I did actually state I would buy 2, not 1 = 6v not 3v.

My assumption is, after the weeks I have spent researching these things, to provide here, because nobody else could be arsed, it would take someone maximum 10 minutes to examine the listed components and provide an answer on the specific examples given which doesn't have the word "depends" in it.

All of the variables are there. Failing a direct response from anyone ill just hook 6v up to the arduino and servos separately and pray it doesn't fry my stuff. Like I said I have no further time left on this and my inbox is flooded.

As you know I'm great full for the comments you've made on this thread, but that assumption was below the belt. I honestly feel as if you accusing me of having done nothing here.

*Frustrated*

 

[7sinzz]

Also the resistor is mentioned in the first post it's between the switch and gnd. Whether that's doing anything or not I don't have a clue.

 

[xl97]

Sorry you are offended..not my intent.


good luck.

I don't know what I'm doing with regards to electronics in general, but I have learned specifically what was required up until this point, for this specific project. I could easily spend another few hours studying the final part I'm sure, but as mentioned, i dont have the time. I guess I'm just kinda hoping someone else is willing to take it to the final hurdle in my absence. The reason this thread is written by an COMPLETE amateur is because IMO the full tutorial, and every detail required to get from a-z in one place doesn't exist. As I've had to learn it anyway, I decided to document my progress so others don't have to. I've hit a wall, and asked for simplistic help...

If this has been done before, in its entirety, every little detail, including the EXACT code needed and full schematics, please show me, because after many hours searching I did not find everything all self contained in one place. If it exists then this thread really is a total waste of time.

Many people do take different directions yes, but if we can provide 1 direction here, that is confirmed to work. Why bother? For those that don't have the time (the majority), this is designed to be a 1 stop shop. For people that just want to build, not learn. The majority of people checking this thread probably have no intentions of applying their own rigs, that's why they're here. In the same way that people who download darksides or robos peps have no intentions of ever ceating their own. I have obtained a position which has motivated more knowledgable people into sharing their information. Motivation that previously was not present.

Reference to the final point, again, I said I would buy 2 of them. Equal to 4 batteries! My personal reason for this was because I wanted 2 batteries in each side of the helmet, counter balancing each other.

As it stands the project is not complete because the requirement to work out how much power is needed and how to hook up still needs to be learned. Therefore, this thread is currently not a 1 stop shop. Viewers are still in a position where they need to learn how to calculate the variables from a third party source, and then actually do the calculations.

I will endeavour to locate this information and bring it back here in the time that I don't have available.

The remainder of this tut will be written with the parts I have as a foundation. One day...

 

[xl97]

I understand you are trying to outline what 'you' are doing in an easy fashion to follow..

got it!

 

[Andy W]

I had the problem that when the servo "plus" was connected to arduino directly, they started to twitch every time the arduino was doing something else! Powering the servos direct from the accu solved that problem!

Now I'm using 4 servos and a servo controller, because I'm running out of pins on my Arduino Micro! :rolleyes

[xl97]

ahhh.. I see..

I read about that a few times as well..

(maybe noise or dirty power lines)

out of pins!?.. YIKES! lol must be doing alot..

 

[michaudtime]

I'm going to give some of this a shot soon, I've got a few parts laying around, I'm a total newb with electronics tho. Wish me luck, and thank you for the info!!

 

[7sinzz]

Let us know how you get on dude.

I've been spending today on my suit.
I've decided to use foam, PVA glue to seal, plastic coat via xrobots method, fibreglass the inside and body fill the outside. Although this may seem counter productive, I hate pepping and the foam chest took me an hour to make instead of the 8-12 hours with paper pep. Freebie advice for ya all.

Obviously needs some sanding but it was really cold so I had to throw in the towel for today.

Looking good matey, I had nearly all the parts of my suit fibre glassed last year and then it got too cold to continue so the bits are still sitting in my garage much to my girlfriend's annoyance. That's the downside for us poor Brits, damn weather!

Anyways, I've nearly rigged everything up as far as you've got to on the helmet wiring. Just need to get some resistors on Sunday for the LED's and then I can test the code and start to work out how we can all get this things rigged into our helmets.

Very much appreciate all the work you've put into this good sir!

 

[7sinzz]

Thank you HMI, be good to see your progress.

 

[michaudtime]

Just a quick question, I was wondering what people are using to control there setups, I've seen it done with an accelerometer but I'm not sure what people are using to not have to flick there head. Thanks

 

[Andy W]

I'm using voice commands! Sounds difficult, but it's not that hard to do!
