I hope there is still some freedom of speech and this my comment won´t be censored and all readers of Hacker News could see it...Otherwise just ban my account...no need to play childish games...

send me an email and tell me I am out of this comments site also could be an adult talk...

Frewill always evryOne so if some of my comments , because of my operating system , or because Firefox is such a memory hedgeHog and make things slower and buggy or if I misclicked somewhere in the wrong place at the wrong time...All this possibilities are MotherNature telling me what to click and what to write or what to think and , above all in this little specific case, what to publish as comment or abort as unpublished and should be forgotten even by me myself unpublished comment...

So I am happy mother nature helps me...

this headline here, at first sound like a Scandal , really (mark twain aside) Scandalous(new style of avoid SHOUTY/caMelCaSe/spaguettish lack of ,,,comas,,,/ avoidance of verb times conjugations as in using avoid instead of avoidance/ aside, Aside)...

This headline sounded really scandalous for me, because I thought it was talking about weaponry aiming system for war or something, using body heat, and/or infrared lectures to positioning of target and aim. So I have a mental problem and am paranoid and see menaces where they dont exist and maybe hear voices in my mind that dont exist, maybe not, maybe my own minds voice go crazy many times who knows. Maybe similar to veterans who had pos-war traumas and listen to a little firework and jump on the ground thinking its an explosion or aerial attack, but I never had some trauma or shock like that , this is for sure, 100% sure maybe, but well, 100% sure I never been to war or policeman training or any training of this kind (stress and note and tonic on the sentence I said: I was never trained. Never, not even as a soccer player and I am one of the best in the world , yes, soccer player, no analogies or underlines here, but I have never, this is true, wear a professional soccer shoe and , this is true again, I have never played soccer in a soccer match or game or training with other people in a Real Grass Oficial Size or near Oficial Standard Size soccer field. And this is true. So , I repeat: I was never trained...) and I was never in a battle or fight of any kind...so it is not that mental disease as the veterans have, mine is different.

But then I read the article, and you got me, now you know I almost never read any article and only go directly to the comments. You know now that I click 1000 comments page link for each Article headline link I click...I almost never read the article...you know now...I just go directly to the comments page...1000 to 1 is probably a good estimation.

But this one was scandalous and I had to go read and You know I had to go read and they know I was going to go read , so , When I saw it was a parabolic electric heater instantly when I saw the picture, I laughed and smiled and knew It was just a kids Prank...

But then I see really (!!!!!!!!!) "targeting-aim-at-humans' autonomous artificial-driven pray-localization information-processing-system...

very well...

I would speak more about this and why this technology explained here is childish obsolete and naively architected and, at the same time, smart, lets praise the truth, nice one, nice hack, but its like sending a pigeon with a paper attached instead of using Telepathy ( of verbalized thoughts inside the mind) Its like this, when you have Iphone5 cameras and samsumg cameras, and Unity5 for free to process the pixel position info, but I applaude the use of raspberry pi, it is so complicated and obsolete that you need balls and patience and be a Great troubleshooter to make something like he did with home appliances, that said, you can just use phototransistors facing the mobile phone screen to command the opening and closing of the electrical circuits of the power source of your electrical motors ( dont even need steppermotor, actually, normal ac motor would do too) So you dont need freaking messing with conection male and female plugs USB raspberryUsb or whatever you use to send the electrical signs from the phones processor to your raspberry pi robot.

Anyway I dont make this comment too long to increase the chances of not being censored.

thanks evryone...

thanks...
