The headset piece is a camera with a relayed image to the eye via a cup.

If we take this:
https://www.adafruit.com/product/1480?g ... aQodoV0OEw
and use it in the eye piece
we use a camera feed from a raspberry pi
and it relays the image to the hidden eye piece.

Alternately you could set the camera in the IR camera spot in the m56 and have a gun sight view of what you are shooting.

This can be easily done. In all honest the later call of duty games use a variant headset in the games themselves as part of the game character renderings.

This display could work:
https://www.crystalfontz.com/product/cf ... aQodzwwNuA

For the eye piece.

Now also worth noting is that the raspberry pi zero w has bluetooth built-in and there is documentation on how to broadcast the display over bluetooth.

Couple the display with actual heart rate, sp02, ECG/EKG feeds all done with simple DAC/DAS input feeds and then rebroadcast and you have a replica of the vitals logging/monitoring console in the APC.

I would love to see a setup like this at a Con where patrolling Marines have a live feed back to a row of "monitors" (tablets or the like dressed to look the part) at a table display. The vitals would be an added plus!

Bluetooth would limit the distance to a 100 feet or less. I would have to switch to either 900MHz or one of the other ISM (Industrial, Scientific, Medical) bands (2.4/5Ghz and a few other frequencies) for this.

My concern at a con would be interference from other folks bluetooth devices and other wireless knick knacks causing issues. Spectrum conflict and high levels of background noise from everything all together.

Plus for realism we would have to look at a frequency band that can travel through jungles, caves, and deserts and not run into any abnormal issues...

As far as I know outside of possibly DARPA there is no live video feed/ biometric tracking setup that broadcasts remotely with video too. There are biometric telemetry feeds that do broadcast but that is mostly used in the marine and wild life biology fields.

OK as far as video relay. In the movie one monitor was for each soldier pulse and ECG rhythms and the other a video feed.

Ok, now for range you want UHF and VHF frequencies to look at.

Range: 300-1200 Meters in 0.9 - 1.3GHz range
https://www.aliexpress.com/item/1-2GHz- ... .12.NL7rB2

Range: 7 miles in 1.2GHz range
http://www.vfmstore.com/trc12g.html

2.4 and 5GHz frequencies are too congested and have a LOS limitation of 100 feet in open areas and far less with a highly obstructed fresnel zone. 900MHz is another option and you can get a good thousand feed on it as well. Look up FPV video transmitter/receivers as that is what you want. You want to avoid anything that says Line of sight only.

All of this stuff runs on 12VDC. The problem will be battery life. The pi equipment runs o 5V DC.

This will step 12VDC down to 5VDC:
https://www.superbrightleds.com/moreinf ... wAodUCwIMA

Now batteries? AA arrays won't work long. Security system batteries would work as this systems tend to run on 12VDC.

https://www.1000bulbs.com/product/56369 ... wAodXksEug
You want AGM (Auto Glass Matt) batteries as they won't leak like car batteries. It is more of a gel type material and safer to handle for the abuse you would run into in the field. The batteries are thin enough to fit into one of the fanny packs on the belt webbing of the costume. Same could go for the two transmitters. and some of the electronic guts.

The idea of built-in Bluetooth and Wifi on a RasPi that size is making me hyperventilate.

Re: the TFT displays, as far as I was aware the issue with "eyetop" displays has always been focal distance. You need some sort of lens for the eye to be able to focus on a screen that close to your pupil, don't you? Devices like Google Glass and the Vufine project their image through a prism to change the focal length.

Having a working display in my Head-Mounted Sight has always been on the "things I'd love to do" list for me. I've just been waiting for eyetop display tech to become common enough to be affordable.

I think the problem we have at this point is finding micro 1080p displays at the 1 or 2 inch size factor. After reading up on that issue, the best I can come up with is a 4 inch display nestled on an arm to the left or right side of your head.

What part is making you hyperventilate, that you can fit everything on that small of a form factor, or that it is sooooooo bloody cheap?

Thanks for the comment, it really broadened my searches up.
This could be a good screen candidate: https://www.crystalfontz.com/product/cf ... 20x480-lcd

Now if aspect is a concern We could have it 45 degrees relative to your right eye say in a fixed position.

You might want to look into the RC community, what drone pilots are using for headsets, etc. If there's any community that's going to be driving a market for the kind of eyetop display we'd need for a working Smartgun sight, it's that one.

Both. That's the same price as the Trinket Pro that runs the effects in my Smartgun, and nearly as small. The Trinket is still a better product for that particular application, but still. A Linux computer that could fit in your wallet, for $10, AND it's got WiFi and Bluetooth built in? Good grief, the stuff you could make with that... I'm definitely gonna have to order a couple to play around with.

Good luck getting two at once. Most places have a limit of one per customer per order. This pi is one of the hottest pieces of pi to cook things up with anyone has seen to date.

Found a shirt that might work:
https://www.hexoskin.com/

And the material looks futuristic enough to function for the need. I am awaiting validation that I can make the shirt work for the setup. At 200 a shirt, not a cheap part.

OK, apparently this stuff is cutting edge technology. The shirts referenced were shown at the medical industry equivalent of the CES this year.

Google has made a conductive wearable fiber product that can be sewn in like circuits. Products are just now coming to market for this.

Now the core issue we have going on is everyone is getting fatter, everyone is getting more and more health issues at younger and younger ages. The medical community is stumped on how to stop it. From a cardiology perspective you have to figure out a way to take those bulky ECG harnesses and make them more wearable and comfortable encouraging greater compliance in wear studies. The big push now is for those harnesses to tie to your smart phone for instantly available diagnostics.

The fitness industry is going rather gaga over the matter as it can help the high performance athletes have more eyes on their condition to prevent cardiac/pulmonary (heart/lung) episodes and prevent a collapse before it occurs.

OK looks like for interface I will have to go with this unit for a telemetry monitoring setup:

https://www.firstbeat.com/en/

915mhz band in the US, still confirming and I am still confirming some other technical pieces so I know how the setup needs to be setup. I am stall doing some looking and digging on how the protocols at play work to see how they might function in a noisy (frequency wise) with other cosplayer gear present at the other bigger cons.

Once I get hands on I can see what tweaks are possible, but for real time telemetry without a full from the ground build up. I factor in time to my builds and repeat ability by others and time is money.

These folks typically sell to sports team and they work in coliseums and arenas no problems all day long.

Looks like many have already been chipping away at this need:

https://learn.adafruit.com/diy-wearable ... w?view=all

This would be a quick hack to have a regular raspberry pi output at ntsc/pal resolution and frame rates. This setup also would be very easy to hack to look like many of the setups in Call of Duty or other FPS games out there today.

And this came out recently too:

https://www.vufine.com

Just takes a standard micro? HDMI input. Mounts to standard frames for glasses.

The core issue I have found is finding a micro sized 1" or 2" 1080p display for cheap. The bulk of your cost is that as those run at least a 100 but you have to buy a bunch as they are typically special production runs...

I've got a version 1. Short story: it's arse. Brilliant idea let down by the fact that it's not fully HDMI compliant (or something like that), it's very fussy about the input signal you use. I got it working with my phone so I may go back to trying to make it usable one day.

Version 2 is meant to be fully HDMI compliant ... I almost talked myself into getting one. Decided that wasn't a good idea (but mostly due to the disappointment of version 1).



Have recently started up again on trying to get this to work. Current hurdle is finding a camera that's a) sub $100 [ideally under $50] and b) will output directly to HDMI and DOESN'T have an attached LCD (or need a 'control' unit).

I have decided on going with a camera to raspberry pi display passthrough locally. The trick on HDMI is splitting the signal off and not causing issues with the protection mechanisms built-in to the protocol and standards (may have been what you were running into.) Once you split it you can take that camera feed and either pipe the gun feed remotely, or feed the fps helmet cam feed and not split anything all via a couple of raspberry pi zero w units.

I was looking at the 1.2Ghz spectrum that broadcast TV uses as it would not conflict with any other wireless spectrum at a given event and that standard can go a fair ways distance wise and should be 12Volt compatible.

OK here is the initial finding on the gun camera setup:
https://learn.adafruit.com/diy-wifi-ras ... -touch-cam

So much for the vufine.

https://hackmypi.com/PiCamPart1.php
http://www.raspberrypi-spy.co.uk/2017/0 ... tioneyeos/

ok, now looks like I will have to setup a wireless stream of the camera feed on one pie
and
one the other pi set it to auto launch a streaming display on the HUD.

I'll have to do more research on options for rebroadcasting the streams over 1.2GHZ to a remote terminal, but that is old school tech.

OK, some sleep gotten and refreshed I feel. Let us look at it a different way tonight.

How about a 3.5mm composite adapter harness:
https://www.adafruit.com/product/2881?g ... RIQAvD_BwE

OK, let us upscale it to HDMI:
https://www.bhphotovideo.com/bnh/contro ... ku=1208856

Now splitting via audio/video is easy.
Let us look at a transmitter:
https://www.protectiondepot.net/1500mW- ... eiver.html
1.5watt 1.2Ghz 1800-2500 unobstructed line of site (LOS) more with high gain antennas from say here:
http://www.ebay.com/itm/1-2GHz-9dB-CCTV ... 2457714063
Now the thing with 1.2Ghz is that it has been used for CCTV and FPS drone users for a while. Go searching and you can easily find a direction antenna, search some more and you can find a good omnidirectional antenna.

So far I am not finding a good way to stream the camera directly out of the HDMI output. SO far I will have to have a raspberry pi powering each end.

one on the camera for the gun site. one for the vufine display. one for the fps cam and one for the downscaled transmitter.

One of the write-ups on using the pi cam to power a streaming web interface.
http://elinux.org/RPi-Cam-Web-Interface

the first beat unit will relay telemetry and is designed for multiple feeds on one screen. It won't be true to the movie but would include additional telemetry to indicate stress levels so it would be true at its core.

And researching on prototyping the pentax camera it does appear that someone has thought of using a pi with a pentax lens:

https://www.kickstarter.com/projects/sa ... og-cameras

I'll see if I can find something further as this will make for a truly immersive thing.

And I found something:
http://www.truetex.com/raspberrypi

I am not really fond of radiating 2.4Ghz microwave radiation anywhere near living tissue, but, the pi zero w with something like that could work but the housing would be slightly off. I think the minor variation would be allowable if it allowed for a true head-end presentation of the video feed...

OK, this lens looks really close to what is in aliens:
http://www.ebay.com/itm/like/2631523304 ... dispItem=1

Is there some agreement that if we try to make it look really close to the movie pieces without breaking the bank the costume would pass muster?

OK got the displays to work on a streaming display. Also got the headset in. I think with some hacking I can make it work. It looks like the headphones run on 3VDC.

I used an adafruit screw terminal to TRRS adapter. Works great with my iphone. Not so much with my playstation remote. Apparently there are 4 different TRRS standards and they are pretty much manufacturer and application specific. The design on the ear phones allows for easy resoldering and custom cable options. Of all the hardware hacking I have done this was one of the easier bits.

Microphone is red, ground is ground, Blue is Left, white is right. Works great on the iphone.

If you are getting static you have the microphone switched with one of the speaker wires.

I'll get the model and maker on the phones and post when I get home.

Hehehe, I am running out of money this year. I am still getting big ticket parts orders put together. The more technical pieces will be very expensive. I decided on the smart gun I will just run an HDMI cable and just pipe the output to a vufine HUD. For the small high resolution displays, the order minimums and costs were too high. I am still researching the edmunds optics catalogue as I think they have some adapters I can use to get a cheaper varifocal lens looking setup in place. As far as the helmet cam that is where I will have to pipe the output out across RCA cables to an 800 Mhz video/audio transmitter. The telemetry feed I settled on firstbeat.com setup though at 2k for a basic setup, money and time are my enemies.

I also have the predator backpack and dual animatronic cannon setup I am still throwing together and even that is looking at close to a grand in parts total.
