helmet motion sensors?
« on: Jan 13, 2017, 06:27 AM »
would having a small PIR motion sensor on the rear of your helmet be a cool idea? (https://www.youtube.com/watch?v=bEooGzn1trE) Sorta like a mandalorian reverse camera but to tell when some one is behind you? watcha reckon?

Sounds cool vod! I'm new here but that's an awesome idea. I've though about getting some kind of camera or something to use as eyes in the back of my head.

I am a 'functional' junkie. I like things to look cool... but if they actually DO things, even better.

I'm working up some sensors as well. That sounds right inline with something I would do, so it's got my vote. I vent a step further and went for a video feed. The camera I'm using can be positioned for forward or backward perspectives. (It also has night vision).

But what I was considering is two cameras. I can only stream one feed at a time, so I was wondering how would I know to switch the feed from the forward facing camera to the back facing camera.

Pretty sure you just answered that question. Motion sensor facing behind is triggered telling me to change feeds and boom. I got eyes on my 6.

bookmarked to say the least vod. Cool idea.

I'm curious on knowing which camera is small enough to carry it.

Shouldn't be hard to find a camera small enough to fit. There are tons of tiny drones with FPV cameras, that are designed for a live feed, so they shouldn't be too tricky to get.

@Zando: OMG, fpv cameras didn't even think about it and it's a perfect solution. Small and with transmitting modules.

In addition to those... the various forms of "nanny cams" also offer very very small cameras. Depending on which make/model, HiFi res and night vision are supported. That's the route I went. They all work on secure wifi connections. Connect with most all phones. Offer live feed and recording options and are mostly all under $50.

Check out my thread for the camera build I did here for details, pics and links:

Blame my uneducation if this is a silly question, but would a PIR motion sensor work on any moving object?  Based on the video showing off the sensor, it detects change in ambient temperature, and is extremely sensitive.  So, if every time you move, would that not set it off, since the temperature read would constantly change?  Maybe there is a different type of sensor that works more adequately for an already-in-motion object? You might need an area-reflective or ultrasonic type of sensor in order to make it work efficiently.

If I'm missing something, please tell me, because I'm always wanting to learn new stuff :D
I will be following this thread closely!

I was thinking something similar. That if the sensor is mounted on something that is moving... back of the helmet, then it could potential cause stationary or in-motion items to set it off as you walk past them.

An ultrasonic sensor that can be positioned and shielded to be directional might be a better approach. Time to start prototyping and testing!!!

Ain't life wonderful?

Pir sensors detect changes on the infrared radiation they receive, as soon as they start moving the amount of IR received varies and they won't work. Ultrasound sensors are the correct option as seen on many Arduino robots. The usual one has a reach of around 3 meters.

Could these sensors theoretically be connected to lights tjat turn on when someone is in the corresponding direction, telling you to turn your head?

In theory, yes.  It may be easier mechanically to just set up one to each side separately, but the boring devil's advocate in my head just simply replies," why not just use a mirror?

Now, if you had a gadget that would turn and focus on that particular side, like a targeter or scanner, THAT would be awesome!

I also think about use in conventions...if you had something light up when detecting someone beside you, you would light up forever... ??? ???

At this rate... you may end up with a full Heads Up Display! Then you can add motion trackers and facial recognition, scanners that detect projectiles and tell you to duck, a targeting system for wrist rockets...  :P

don't forget lighting all around the armor to indicate mood...

Red - Angry
Green - willing to negotiate
Yellow - Be cautious
Blue, White, Black and every other colour - Keep your distance!  :P

The line between Mandos and Predators starts to blur. Next thing we know, Department of Defense is hiring us hahaha.
