Disappointing DMD Policy

Andreas Gene

Other Parts Discussed in Thread: STRIKE

Dear TI Forum Members,

I have been very aroused the last two weeks when I 'discovered' the DMD technology as it solved with one strike a couple of my problems. Like many here I'd like to produce defined laser light patterns with 1-5 kHz frequency. After some forum search I found out that there's no way to directly manipulate the mirrors unless you possess a e.g. Discovery 4100 Development Kit. This already disappointed me a bit ... but well ... no big problem as there are these kits. So I contacted  my local dealer and realized that these kits are sold for about 10'000 $ which by far exceeds the budget for a 'development' at university research level where there is a quite high possibility of having negative results.

Please don't misunderstand me ... I like and enjoy TI products but I cannot understand the price for a Kit which actually is made to spread the technology and allows development and ultimately leads to increased sales volume.

So ... what now? Where is the error?

 

All the best,

Andreas

    Hello Andreas,

    Welcome to the DLP section of the TI-E2E Community.

    I am sorry about your disappointment. It sounds like you are looking at a D4100 1080p kit.  Do you require 1080p resolution for your research? 

    If XGA resolution will do, you may consider a LightCommander kit made by LogicPD from our distribution channels instead, such as Arrow.  These kits have an MSRP of around $3610 and come complete with an illumination module and optical module.  However, I believe they are currently on backorder.

    This kit is designed so that you can remove various modules that you need and mount them to an optical bench.  Although not as fast as the D4100, the LightCommander kit is capable of up to 5000 binary patterns per second, just in the range you need.  It also has a number of other features that will make it easier to get your research going, such as a 960 binary pattern memory on the controller board.

    Hello Fizix,

    many thanks for facing the admittedly offending thread. And also thank you for your advice regarding the LightCommander. However I only would need the mirror chip and a possibility to manipulate each mirror individually -  very fast. And I actually would not like to buy a whole projector either the Pico or the LightCommander just to play with the mirror and discard the rest. Whereby I would accept buying the Pico because of the low price ... however my planned task wouldn't be possible anyway with this device i guess. 

    I found a simple alternative ... something like the 2D pointing mirror TALP1000B but much faster.

     

    Best regards,

    Andreas
