  1. Closed: Re: Suggest device for 100+ FPS camera board

    Yes Andre, that's all the need as of now.
    The whole issue is about interfacing to a particular camera chip, else it all would've been done by now :(
  2. Closed: Re: Suggest device for 100+ FPS camera board

    I could get an ARM+GPU - am currently thinking of using a Beaglebone black or RPi2.

    Sorry I missed these details but I do need a real time unit. The principal function is to grab images from the...
  3. Closed: Re: Suggest device for 100+ FPS camera board

    AFAIK, what andre has said stands true. And even more so with Linux. I see lots of context switches even when no "extra" software is running...and a processor, I suspect, would miss out on some...
  4. Closed: Re: Suggest device for 100+ FPS camera board

    Thanks.

    I need very little image manipulation (maybe a little image cropping and such).

    I said VGA resolution. But forgot to mention that it's at 8-bit or 10-bit depth (depending on what image...
  5. Closed: Suggest device for 100+ FPS camera board

    Hello,

    I'm a researcher trying to build a device that grabs RAW monochrome VGA images from a fast, LVDS camera (100+ frames per second) and stores them onto a SD card, and also drives a touch LCD...
  6. Closed: Re: IR controlled DC Motors using arduino uno

    Looks like a nice video.
    BTW, why did you post it here? This is the forum for asking for help. Better move this to "show your DIY"

  7. Closed: Re: Generating and comparing waves with different frequencies using arduino

    What frequencies do you wish to generate? If they are low enough then you could use PWM to generate them.
    Also, what do you mean by compare them? Compare what - frequency ? amplitude ?

    Closed: Buying 3 axis translational stage

    Hi all,

    I need a 3 axis transnational stage. I've looked at the top search results in google (thorlabs, sk advanced etc.) and boy, are they expensive!
    Price point is a big issue since I'm trying...

    Oh, got it.
    I'm keeping my fingers crossed!
  11. Closed: Re: [Moved]high speed link between uC & Android - possible ?

    @FvM : Oh yes, that's a typo. It should read 4 MBps
    Thanks !
  12. [SOLVED]Closed: Re: MATLAB Code for Latent Fingerprint Enhancement via Multi-Scale

    (1) It might help to remove the [solved] tag
    (2) It would definitely help to ask for help on building the code (rather than the code itself - I don't think anyone would provide you that here. At...
  13. Closed: Re: Recommendations: Camera module for Raspberry Pi/Beagleboard

    Oh really sorry - I didn't notice it's a link.

    I have now sent them an email requesting delivery to India (although it's strange that they are selling a $3 part for $76. What a huge margin!)

  14. Closed: Re: Recommendations: Camera module for Raspberry Pi/Beagleboard

    @anandpv : Unfortunately, I absolutely need global shutter. But I'm curious about your comment on RP - it's 1 GHz, 512 MB RAM. Shouldn't it be able to record a 100 FPS VGA video (my calculations say...
  15. Closed: [Moved]high speed link between uC & Android - possible ?

    Hi all,

    I need a uC that can take about 400 MegaBytes / sec of data via a serial port (from a monochrome VGA camera @ 100 FPS) and pass it on to an Android tablet/phone.

    The questions popping...
  16. Closed: re: Recommendations: Camera module for Raspberry Pi/Beagleboard

    Could the more experienced members suggest how should I go about searching? I'm currently just fishing through the internet with Google as the hook.

    Is there any structured way to go about it?
    ...
  17. Closed: re: Recommendations: Camera module for Raspberry Pi/Beagleboard

    Hi

    I've looked at that one and it doesn't satisfy my biggest requirement - global shutter
    :(

    Thanks for the suggestion anyways

    [General]Closed: Re: Connect DC motor to microcontroller

    You could always try hall effect based current sensors...I remember seeing them a few years ago and noticing that they themselves do not draw much power.
  19. Closed: Recommendations: Camera module for Raspberry Pi/Beagleboard

    Hi all !

    I need to buy a (rather rare?) camera module to go with my Raspberry Pi or BeagleBone.

    The requirements are : Global shutter, VGA or better, 100 Frames per second or more, monochrome,...

    Hello Gents & Ladies,

    Thanks BigDog!

    I'm looking for VHDL too. After a bit of googling I inferred that both VHDL and Verilog are used but verilog might be more ....familiar... for someone like me. So I asked for that....

    Hello people !

    I have been working with microcontrollers (PIC,AVR) for 2+ years.

    Now I'm moving to FPGAs. About to buy a NEXYS2 board. I've got Xilinx ISE10.1 too.

    Closed: Re: Pic16f877a analg read problem

    You are lucky to get such small variation without any filters.

    Are the analog and digital grounds separate on your PCB ? If no then try to do so.

    An analog filter ( just a simple RC one) is...
