sltvm2007 have started to explain all the details of his DIY laser projector on another forum: Laserpointerfoums
http://laserpointerforums.com/f47/ho...-tv-32628.html
Actually SLTVM2007 has not explained a damn thing. We knew it was a resonant scanner from day one. He may have given details of a resonant structure, but parts of that do not add up. He does not explain how to correct the phasing and drift of the resonant scanner. Commercial systems that do this have complex feedback networks, etc.
The fast green direct DPSS modulation, albeit at very low powers, has yet to be explained.
Oh, wait, you are sltvm2007... Trolling for your ego?

isnt stainless steel non-magnetic? how is he using an electromagnet to vibrate the stainless steel? :rolleyes:
(me not making any statements about the mystery projector)
If a material is not attracted by a permanent magnet, does not mean it has no magnetical properties.
Classical example: take a coin that is not attracted by a magnet, lay it on a wooden table.
Now quickly move a strong permanent magnet parallel to the table over the coin.
It moves ! Even though it wasn't attracted in the first place.
Restoring torque of Kuntman's scanner is very strong, hence it has a very sharpQuote:

This scanner has these main features:
- No MEMS
- No acousto-optical-modulators
- No need for complex feedback controls.

Reply to flecom and -bart-
Yes you are right. Stainless steel is usually non-magnetic. Mirror material should be magnetic. By the word 'stainless' we have intended to mean 'good reflectivity'.
Thanks.
Hmmm, we've been here before haven't we... O_o You even earned an "FU" smiley didn't you? *vigil
Here is a diagam for high speed analog DPSS green laser. And there is a picture of an image scanned by using this.Quote:

Mechath you dont have to double post ;)
There is a nice edit button whenever you post.
..Well, I was up-late doing a logo-conversion for a friend, which had a 'phoenix' in it... when, suddenly.. it all flashed before me... it's all so-clear now!
..Here's how it all works for the rest of you 'simpletons' -

...hey, what's a little editorial satire / something to brighten-up Steve's day among friends, eh? :p

Hey don't knock the potato, everyone know's its the future of portable laser power:

Seriously though, if this was possible, I believe Bill Benner would have done it given his experiments with the beam brush, which must be a similar principle, and the fact that he's currently developing his own scanners.
However, if I can be proven wrong and you can make Cambridge beating scanners for $10, I will be delighted to be proven wrong.
Good job.Quote:

Dear methhack -
Good, glad you took it in the 'spirit' with-which it was intended.. Only 'point' was - kudos to your pioneering-spirit, and-all - that's what this place it all-about - but,Quote:

Jon, you forgot the "666" timer chip.
ROFLMAO.

Think you've cracked it now Jon with the Flyback control.
My old physics teacher always used to say things are twice as efficient with the ex-wife out of the way!
(Never did say HOW he got rid of her though :knife:)

Beam brush does work but it's just not perfect, not sure what point ur trying to make here.Quote:

Instead of bashing someones current projects, you might as well contact and inquire more information before you do something like that.
I was having a bit of fun. The Youtube vids of it working are seriously impressive.Quote:

The point I was making more seriously above was that from a laser scanner point of view, as opposed to a tv scanner point of view, if this technology was so good, don't you think Pangolin would have realised when making their beam brush that this had a projector application as I believe its a similar principle to that used for the beam brush.
As a tv scanner, I'm not knocking it, in fact I'm very impressed at the skill.
View this and compare with your beam brush

If you think you're onto something with a Projector scanner application contact Pangolin. I know in one of the LPF threads you were seeking someone to take this on commercially, you never know.Quote:

I see the artists signature on the fourth pic.

Now I know BTW Bill.
I see his photo.
And put here a self portrait. Made 26 years ago. When I was 37.
I dedicate it to jon.
I cannot understand the jargon of your generation.
And because of lack of my English, I prefer to express myself by pictures and graphics.
Good Sir Mec -
Very-nice... Looks to be oil.. clearly, you studied-well, nice brush-work, nice tonal-build, expressive color... I won't post any of my opaque-medium works.. I'd rather that the perception of my motives for doing-so, not be 'mis-interpreted'... ie: I did not post the pencils to 'compete' or somehow 'put you down' - nor was the 'editorial comic' meant to be 'harsh'... Just a good-humored 'jab' at the somewhat, shall we say, 'undercooked meat' of your design / proposal-details... theres' some pretty-savvy tech-people, in here, and they will pick-apart any 'brainchild', that gets posted here... like coyotes on a carrion ;) ..which, imo (in my opinion.. :) is a good thing... :cool: ..we all-learn, that way...Quote:

Thanks jon, for nice words, encouragement and advice.
You will find bellow a picture of an image projected by my scanner.
I hope you will consider this one also as an art work.
