I didn't want to buy Google glass so I made Pi Prism thats customizable.

Hackaday Challenge 2017 Section

------------------------------------------------------------------------------------------------------------------------------------------------

Challenge the project addresses
  • Dangerous protesters and rioters with masks destroying property and harming others, without the thought of any consequences through there anonymity.

How will alleviate or solve the problem that the project addresses?

  • The theory of identifying a masked person in real time, reduces there chances of them causing a crime.

Discuss how the project might be world changing.

  • Reduces crime, inspire someone else to build a better live facial recognition api.

In theory its simple.

Add a Pi Noir V2 IR with either 680nm, 720nm, 850nm, 950mm Filter to see through the black masked material.

Use Facial Recognition API,depending on the API use facial search matching, gather info which is shown on the prism.

Besides that it can be used for other things as well.

Publish at least one (1) image illustrating how the project might be used. This may be a sketch, schematic, flow chart, rendering, or other type of image.

I'm assembling a low cost kit, also the prism will be a lot thinner, with the pcb instead of wires.

5/10/16 Im sold out of pre built prisms.

New Video of the Pi Prism Added new 16.5 x 38 DCX lens. With the Penta-prism the people facing you do not see the screen (mainly for privacy). Also I made the eyepiece bridge longer.

Blurry Picture taken with iphone (the screen is crispy clear irl)

OCR recognition demo above

older video of a Short demo of Pi Prism(with 14mm dia 20mm focal optics) with varying brightness sensor and prism.

I saw a comment on Thingiverse where you are selling the Pi Prism. Is there a link where I can check it out?

Jdomville@stny.rr.com

Thanks....

  Are you sure? yes | no

Your components lists a Raspberry Pi 3 - isn't this for a Raspberry Pi Zero?

Also, this is perfectly laid out for what I was going to do. I'll copypasta for the use case of real-time closed captioning (google speech api - or Mycroft).

Also, with chromium, there's a new nugget for dev build for AR implementation: https://github.com/googlevr/chromium-webar

Can you give more detail about video module

Impressive work, really compact optics. Nice to see another wearables geek! ;-)

Very nice project.

Can you give more detail about the optics / prism, where to buy etc.

Do you think this monocular will fit also?

Thank you!

The optics I used are from 
http://www.edmundoptics.com/optics/optical-lenses/double-convex-dcx-spherical-singlet-lenses/15-19-9mm-experimental-quality-double-convex-dcx-singlet-lenses/3492/
its the 16.5 x 38mm FL, Grade 1, Double-Convex Lens
The Penta Prism i used are
http://www.ebay.com/itm/Prism-Quarton-Beam-Splitter-Penta-prism-10-1PCS-/282241559565?hash=item41b6e86c0d:g:BooAAOSwbYZXe39N 
The monocular will fit but the optics FL may differ since the micro display size might be different. Just measure the focal length between the stock lens and the micro display.

  Are you sure? yes | no
