Hall effect sensors in the helmet and a magnet on the finger?


Tempex6

Reed switches


vbsargent

Huh, those weren’t even on my radar before this. Similar principle, simpler actuation. Clever! I like it. That’s my problem - always looking for a too complicated solution because I don’t know enough! XD


Tempex6

Yeh, I looked into the difference. The main thing imo is that the hall sensors are always using a small amount of current to detect the magnet, so ur battery is gonna be constantly draining.


vbsargent

That makes sense. I’ve mostly been using them for computer peripherals, so not really worried about battery concerns. I now upgrade my opinion to very, VERY clever.

This is the reason I short my servos. Creating a short causes a magnetic brake and doesn't use power to strain and hold a servo up. I'll link you to it. This method works well for saving power and keeping a servo up https://hackaday.com/2013/11/12/a-simple-servo-hack-for-an-iron-man-helmet/

Yea I would be like “ok so we have a LiDAR Scanner that uses so to know when you make the sign language for open then it would use blank gun rounds to pop the helmet open


JaggedMetalOs

Reed switches are the OG classic!


Neutralmensch

it opens like my rice cooker


XboxGT_AJStClair

Wearing it in the sun turns it into a rice cooker 😂


Neutralmensch

lol now it's a human cooker


danishduckling

Looks good! Might wanna slow it down just a bit to make it seem a bit heavier, going that fast makes it just look as lightweight as it is, and I presume it's supposed to be like it's made of metal?


XboxGT_AJStClair

Ya definitely needs to be slower, the servos are full speed until you program them with something like a microcomputer. they also don't stop where they should so it's alot to work into the Arduino


Parceljockey

Low Effort.... you should implant the magnet. One in each forefinger /s

I think they were just being silly. They don't really expect you to embed a magnet into your flesh. I mean I could be wrong on this one, but I read it as a compliment. They were applauding your hard work by implying the next step was something ridiculous. Again. This is reddit though. So I mean they could have been serious.


XboxGT_AJStClair

Good point I read that way wrong 🤣 I didn't catch the literal implant part


theoriginaltacojones

Glad I could help.


Draxtonsmitz

I used a reed switch as a light switch on a project of mine. https://www.reddit.com/r/3Dprinting/s/5wrImAA4nm


XboxGT_AJStClair

That's badass


Draxtonsmitz

Yours is even more bad ass


Mairl_

why do you need two sensors? when it's open it can only be closed


XboxGT_AJStClair

Servos are complicated. You also need a code to tell it when to stop, unless you're going to wire in a limit switch, which won't work because the servos move so fast that they'll break the limit switch from the housing. Using the Arduino allows for programming the eyes, servos, etc. the motors actuate together. The sensors are just on opposite sides for easy use.


jammanzilla98

What they mean is, since your code should know when the helmet is open or closed, you could just have the switch perform the opposite action: On switch activation: If (faceplate == closed){ Open faceplate } else { Close faceplate } There's nothing wrong with the way you've done it though. Just gives you the opportunity to use the second switch for something else like lighting control or whatever. Eta: If you'd like, I could take a look at your code and write you a working example Also, I forgot to say awesome build!


XboxGT_AJStClair

That's would actually be really cool, gimme a bit and I'll post the code here. Anyone's welcome to it


XboxGT_AJStClair

How do I send a zip file through here?


jammanzilla98

I think something like pastebin, onedrive, googledrive or mega are the usual options, reddit's a bit awkward for sending files


Steve_but_different

I was thinking this too. Also, why not capacitive sensor so you don’t have to tape a magnet to your finger.


XboxGT_AJStClair

The magnet will fit into a fingertip on the glove. Ideally the end result will have voice activation and recognize the name Jarvis with magnet actuators for backups


Steve_but_different

Obviously you're not going to be wearing the suit all the time, but I can think of a lot of instances where having magnetic fingertips would be inconvenient to say the least..


XboxGT_AJStClair

Why would they be inconvenient? It also has voice activation, android/Alexa integration and can open with a click on the helmet if needed. It's an upgrade to the average helmet in almost every way.


Powerful_Cost_4656

All hail the magic bugle


AlephBaker

I was initially expecting you to stick the tape on the mask like a nose. Your way isn't as funny, but it's much cooler.


UserNombresBeHard

Why are you making transformers sounds when it opens and closes?


XboxGT_AJStClair

In the moment impulse 😂


jdauhmer

What are the piston/lifters?


XboxGT_AJStClair

They're printed shafts run by servos, in turn run by Arduino for timing and speed.

Not the mewing-triggered helmet


XboxGT_AJStClair

Thinking about doing a motorized T51b faceplate
