Holovect kick starter, real or bullshit?
« on: October 19, 2016, 01:34:19 am »
I was browsing through kickstarter when I came across a project claiming to have made holographic displays in open air. https://www.kickstarter.com/projects/2029950924/holovect-holographic-vector-display/description

It turns out the same guy has an indegogo campaign that has some red flags. https://www.indiegogo.com/projects/tootz-the-unicorn-funny#/ First red flag, his last name, it's just scrambled letters and numbers. Second, it's flexible funding, but hey it's only a farting unicorn made from plastic. Third flag, the delivery date lines up with the end of the funding time for holovect. For those wondering how I connected the dots for it to be the same person, since the last name is just crap, watch this video https://www.youtube.com/watch?time_continue=1412&v=KltmVZtnGy0 Jamie is in the video and at the end he's advertising the farting unicon.

Now back to kickstarter, if you view his profile you will see he failed his last holovect campign that asked for $350,000 and his newest campaign asks for $45,000, the same project just 1/7th of the funding required, what's different between them? If you stop there video at 1:20 you can see some fake reaction from Jamie's friend. He goes "oh wow", pretending the thing is turned on, but if you look at the screenshot it's obviously not turned on. This could just be nothing, but hey I want too look at everything.

 Maybe it's legit, in fact I hope it is, it would be cool, but I'm not a physicist. I figure maybe people here would have more of an insight. Everything here could just be nothing, but the fake last name on indie gogo makes me suspicious.

It looks legit, but useless. It requires tons of power to keep air heated to create different refraction index. It also needs a fan to pump air evenly from the box to outside, which is bound to be noisy.
The current model has shaky image, which comes from uneven air flow. They could solve this by using a controlled fan array, which adds noise and cost.
Also, a great deal of noise comes from the fast moving mirror galvanometer, which is the source of the clicking noise when it returns to its original position. Though this can be solved by incorporating DLP technology, but the cost will go up.

I consider this to be the ultra fancy stepped up version of rotating LED displays used in tech stores, but any practical uses? Maybe not.

This would be a great thread in the Crowd-funding section of the forum. What I'd like to understand is how do they get it to be brighter at that one point along the path of the beam? And what is that surface below the object that looks like a square speaker of some kind? How does that help the laser get brighter at that one spot?

[EDIT: Is it just focusing the laser on a single spot, and you need the fan to blow air there to cool the air? Notice in the video here at the VERY END when he puts his hand around the object, the image gets disrupted when the hand is over the "fan".... It looks as if it is actually using a curtain of dust/mist to generate the screen that the laser interacts with to give you the bright spot: http://www.craveonline.com/design/931297-holovect-real-holographic-projector-inspired-star-wars#/slide/1]

if u have a dusty lab two mirrors hot glued on to DC motors, and a laser , can u reverse engineer this  :popcorn:

I have some laser diodes and a hair dryer at my disposal.
