Hi everybody,
i have another question regarding to micromirrors.
Are other manufactures of micromirrors then www.mirrorcletech.com.
I'm looking for a micromirror with about 3 mm aperture and a tilt
angle of about +/- 8°.
It is very importent, that the micromirror can hold its position very
accurate (not only resonant mode). The mirrorcletech mirrors are very
nice but nobody is answering on my emails.... maybe they do not want
to sell their components....
Thank you for your time and consideration |

Guess that is where he should be going. Then again, he's probably some
experimenter that has heard of them but doesn't know (because he didn't read
all of the advert. blurb) who is doing them. And probably, because he isn't
attached to a company interested in using them, he's not got a connection to
TI.

Trying to get any non-standard product out of TI in regards to the DMD's is
hopeless! I was hired by a very large company backed by an even larger
company (whose name in the entertainment biz can't be missed) to look
into developing a special purpose projector for use in cinemas. First
place I went was to TI, and after getting some 200 pages of legalese
in the post, and about 30 phone calls and emails, without once ever
talking to someone on the DMD program, they came back with..
"your project is not big enough for us to consider at this time, thank you"...
I mean, a company like D****y, on behalf of sub owned by Mr. Speilberg,
wasn't "Big enough"?!!!
Well, hopefully they may have changed since then now that these things
have become so common, but still... I've never, ever had been treated
like that by any company in all of my 35+ years of contract development..
GRRRR!!
d.
Hopefully, your milage will vary |

I CAN understand your feeling on that! Been through it on other things wiht
other companies. Found that often, the problem is that the companies in
question have agreements to not discuss the product in certain ways.
My final word to those are letting them know that I'm going to another
technology because I can't get anything out of them for their technology.
It may be the perfect application but I can't get any answers.

DMDs should be cloned soon enough. I actually can't wait for someone
to do it.
I went to TI with a academic research request on behalf of the US
Air Force and got nowhere , too. Got told 13,000$ just for a sample.
Could not get past the lady hired by the technical marketing firm TI
hired. I wanted to speak with a real IT engineer who would have
realized what we were trying to do was important, not a marketing
person to whom I could not disclose diddly. This "exclusive
marketing" strategy should cost TI in the long run.
Then a year later they sell a cut down demo kit via Digikey for 300$.
Argh!!!!

Kinda along the lines of my nighmare.. Was contracted by one of the largest
entertainment co. in the world to look into building a very specific type of
projector. I guess my ND has probably expired by now, it was to be a 2 or
3 line character projector to project sub-titles onto films in real time, so,
lots of potential theaters if the price could be reasonable. So, I told TI
up front that I wasn't going to be competing with existing projection
clients of theirs. That seemed to make them happy, and they already
had an "engine" that was close to what I needed. But then they came
back and said the project wasn't "big enough".... It was an amazing
day when I had to phone my client back and tell them that TI didn't
think their project wasn't "Of significant potential"...
I guess I should have told them I was going to project targets onto
tanks or something..
And likewise, I never got to actually speak to any engineering staff,
only someone's secretary in Marketing. And folks wonder how the
GM's, etc. of the world run themselves into the ground, anyone ever
catch "Who Killed the Electric Car?" A real eye opener into how
not to run a company..
Double GRRR,GRRRR!!

Amazing that TI destroyed the TMS9900 in exactly the same way. Asked
salespeople to say which peripheal chips they could sell. But without a
reasonable range of peripheral chips the processor never got off the ground.
If they had got on and done an ADC and FP chip, they might have achieved
something.
Hey ho. Nice to see that some people never learn. |

I believe the original poster is inquiring about single-mirror
devices, not micromirror arrays. The Mirrorcle device is a single 2-
axis-steerable mirror on a DIP chip.
OllieH - are you familiar with Cambridge Technology galvanometers?
They are much bigger than DIP chips and a single galvanometer is only
steerable along one axis. But they can be stable to a few
microradians. |

Hi David,
i'm familiar with Cambridge Technology galvanometers and we are using
one of these. But we are looking for a smaller single-mirror 2 axis-
steerable solution.
The Mirrorclemirror device is very interesting and should be a good
solution.
Have you experience in using the Mirrorcle devices? |
