It’d be nice if you let me know what you use them for, this stuff had been featured in the strangest Asian magazines, academic projects, scientific publications, but mostly a great lot of hobby projects of other people i have apparently inspired, which I really like to hear about, or maybe want to be involved with!

Hi, I’m Tim Zaman, 22 23 24 25 26 27 28 29 30 y.o. and I’m currently a software engineer for NVIDIA’s deep learning (“artificial intelligence”) AI-Infrastructure (link). That means: I sit behind a keyboard all day and expertly type in a sequence of keys. My peers refer to my resulting produce as “spaghetti”, named after a delicious Italian meal.

From 2013-2016 i was doing a part-time PhD in the development of imaging devices for cultural heritage applications at the Delft University of Technology (NL).

The other part of the time I’ve had my own company, working with software and hardware for cameras. Notably working on digitisation software I created for the Smithsonian Museum, MoMa and many others.

I like cameras, software, hardware, electronics, programming, electronics, education, finance. In real life, I have my cat Taco and my ladyfriend Dany, not specifically in that order.

I would appreciate it if you left a comment below, or don’t hesitate to send a more personal message to:

    Hi Tim, have just viewed your Polaroids From Space project and I am starstruck. As a Polaroid enthusiast I have seen already the camera under the see but the space? Wow! Hope you do not mind me to share your project on my FB profile, or course credited to your account.

    Tim, do you enjoy the arts or just a computer genius?

  3. ferrandis says:

    My query regarding 3D printing is that I am performing textured digital painting. As if it were painted by hand in a new digital technique OWN. Giving the visual impression, of the old masters in painting. With the texture of the old (Gotelé) system in the houses.
    Today it is possible to print this in 3 D.
    It would be decisive for my works, with great innovation in the world of art and painting.
    To see images of works, in Instagram.

    I would like to buy such a picture. Is it possible?

  5. Saar Kariv says:

    Hello Tim, my name is Saar Kariv and I’m a bio medical engineer.
    I am a part of a team that developes a novel quantitative imcroscopic imaging system for rapid and automatic detection of multiple diseases.

    we want to use the computational power presented by the GPU to rese an image of the size of 512*512 pixels to 2048*2048 pixels.

    i read in your websetethat you made performace tests of CPU vs GPU:

    in one of the tests you used the resizing function offered by openCV.
    my question is:
    what are the input and outpt image dimentions?
    where can o find performance data regarding the resizing of 512*512 to 2048*2048?

    thank you very much!

  6. Hello Tim,

    My name is Steven Kaiser. I create oil paintings that can not be duplicated with Giclee due to the controlled impasto (controlled bumps) created. Your technique should, however, work.

    My rep and I have been trying, unsuccessfully, to find someone in the USA that can create archival duplicates of my pieces. (normal inks can not be used, they must last at least 100+years- gicleés use pigment based inks, for example) and there may be a thousand or more created (out of all the real art, together).

    We have found a place in in Germany, Russia, Japan, and Australia, but not here, in the USA.

    If you know of anyone in the USA, or if you know of a way you could do this in the USA, I would appreciate it if you could contact me at 336-355-3874, or email me.

    However, I do not have any electronics at home including a computer, so the best way is to call me because I may not get your email for a week or so. If you prefer to email, that’s OK though…

    Thank you,
    Steven Kaiser

  7. Pablo says:

    Hi Tim! I’m Pablo and I found your website because we are developing an autonomous underwater vehicle (AUV) with parallel image processing in order to compute underwater images.

    I want to use parallel programming to process those underwater images, and we need to choose an embedded computer with NVidia in order to use the CUDA libraries with OpenCV, Do you know which solution is the best to his requirements?

    Any advice you can give me, I’d appreciate it very much.

    I’ll take a look at your blog , it looks very interesting 🙂 thank you very much .



    • Tim says:

      You can go for CUDA or OpenCL. CUDA is often a lot of hassle with installing drivers and such, OpenCL is very straightforward and fully implemented in OpenCV. Just build OpenCV with OCL support. Instead of the ‘cv::Mat’ structure you will use the oclMat structure. Programming is very much the same. Note that building with tbb can give you a big CPU speedup though, multi-cpu is often just as fast as gpu.

    Hi Tim,

    I am part of the San Diego State University Rocket Project and we are working to integrate radio telemetry and saw your article showing some PCB breakouts you had designed: http://www.timzaman.nl/?p=2227

    Any chance the schematic for the XTend 900 module is available for download at an alternate location? The link seems to be broken.

    Thank you,

  9. Olvin says:

    Hi Tim,

    I understand your busy and probably are no longer interested in answering any questions regarding your project from 2011. Nevertheless, I’m very interested in purchasing GPSR components with instructions, please. Do you have an email posted somewhere on this site?


  10. Dr. Rafael Pasculli (Italy) says:

    I would like to have an panting, namely a beautiful oil portrait of a napoleonic general, reproduced by a 3D scanner. Is it possible to have this made by Tim Zaman, or not? Or maybe by somebody else? Trank you.

  11. Wybren says:

    Supergave projecten op je website tim.
    Ik wil met de basis school een weer ballon gaan oplaten. Maar na enig zoeken lijkt het er op dat het wettelijk verboden is om ballonnen groter dan 75cm op te laten als het niet voor wetenschappelijk onderzoek is.
    Hoe heb jij dit gedaan?
    Verder probeer ik bij de hollandse hoogte pagina’s te komen maar het lukt niet.
    Is het mogelijk om mail contact te hebben voor als we vragen hebben?

    Alvast bedankt

    • Tim says:

      Hoi Wybren,
      Ik deed gewoon onderzoek hoor. Ik werk inmiddels op de universiteit, en de term ‘wetenschappelijk onderzoek’ is ontzettend breed. Doe je het uit nieuwsgierigheid en wetenschap? Dan kan dat. Doe je het wegens commerciële redenen? Dan mag het zeker niet. Er word naar ik weet geen eis gesteld aan het niveau van het wetenschappelijk onderzoek. Wel uit de buurt blijven van de luchthavens en misschien een mailtje of belletje naar de luchtverkeersleiding.

  12. Eder Gomes says:


    My name is Eder, from Brazil.

    I’ve tryed to make a test with the code you release on page http://www.timzaman.com/?p=1074 but I got a strange result. During the compilation I got a message that indicates
    ”CN3063 was not declared in this scope” do you know why?

    thank you Tim

    Hi Tim,

    I am Mr. Manohar Pawar from India.

    Above stuff is interesting. i would love to have one sample module for my testing.

    Please send me the details on my email id.


  14. oscar sol says:

    Beste Tim, het reproduceren van schilderijen met behulp van printers fascineert me.

    Kun je me vertellen waar ik de informatie kan vinden die ik nodig heb om een schilderij te printen?

    Of zou het mogelijk zijn dit een keer te komen bekijken?

    Met vriendelijke groet,

    Oscar Sol.

  15. Sang Nguyen says:

    Dag Tim,

    Ik zag het artikel in het Dagblad van het Noorden.
    Mooi en bijzonder project. Je gaf aan dat de werken van jou ook te downloaden is.
    Kan ik de link daarvan krijgen? Omdat ik wellicht ook iets wil downloaden.

    Prettige dag,

  16. Charlie Hamilton says:

    Dear Tim,

    I am directing a documentary about the impact of 3d printing on the art world, and the meaning of ‘original work’. It is not for profit, and I would love to talk to you about the development of your work if possible. Please email me to discuss it! I am already talking to some specialists from Christies, Sothebys and the Courtauld and would love to hear your opinion.

    Many thanks,


  17. Santiago says:

    tim is making excellent but is always several steps behind the technology and science, sell obsolete, but is admirable passion with their stuff.

    “here was link about some laser scanner product that’s been designed by an entire design team(removed-commercial)”

    encourage, keep trying

    • Tim says:

      I guess jealousy is the highest form of flattery. Given the quality of your English, I’ll just assume you are not up to date with the current literature in 3-D scanning. Laser scanning is abandoned. Lasers are for discotheques. More on-topic, my system is 3x more accurate than yours.

  18. nazir says:

    Hi Tim,
    i saw ur old post about gprs gps tracking . im interested in it. but i don have any programming knowledge. can u please help me out setup with step by step instruction on your busy work schedule. i will b so grateful.

    [GPRS GPS] Tracking device

    I decided to make the “Sherlock I” which essentially is a GPS monitor that parses the info via GPRS to an FTP server, which converts it to a website with a simple PHP script to a google maps website-thingy, so that i can monitor ‘stuff’ real-time. I tried it a few times and it worked well. Then i got bored and forgot about it. But not before i made a youtube video from it!

    Parts List

    Arduino or equivalent
    FTP server
    Sim card with GPRS option (i used my unlimited iPhone one!)
    GPS sensor with serial interface (I used a FALCOM FSA03)
    GPRS Hilo/SAGEM module (€40 from Libelium)

    Hallo Tim,

    De Gretag Mini Colorchecker is niet meer verkrijgbaar.
    Is er wellicht een alternatief, waardoor er toch met DELTAe kan worden gewerkt?

    Hoor het graag van je.

    So can I use photos in your site?

  25. khaled emam says:

    i want to site your kinect work in my bachelor thesis. Instead of just using your code in my project with no copyrights and I want to include that your work really helped me. Is there a certain format or details that i should include 😀

    • Tim says:

      Usually i state what’s underneath here. Also, i permit you to change it to a “Beerware” licence (use google to see what that is 🙂 ).

  30. Dominique Steinbrink says:

    This is the perfect post and may be one that ought to be followed up to see what are the results

    A partner sent this link the other day and I will be desperately waiting your next write-up. Carry on on the extraordinary work.

    Beste mevouw Bakker,

    u kunt alles op deze website gebruiken voor wat u maar wilt, en de enige spelregel is enige bronvermelding naar mij of deze site. u kunt de foto’s hier vinden:

  37. Rina Bakker says:

    Hallo Tim,

    Gefeliciteerd met dit geweldige project.
    Mijn vraag: Bestaat de mogelijkheid dat ik één of meerdere foto’s zou mogen gebruiken voor een nog in de kinderschoenen staand project van mij. Mogelijk heb je hier “spelregels” voor. Kan ik de foto”s via internet bekijken? Verneem graag van je.
    Vriendelijke groet, Rina Bakker.

    Kan ik de foto’s bekijken op internet?

  38. Roel says:

    Wat een ontzettend gaaf idee en hoe fraai is het resultaat; wie maakt er nou foto’s vanuit de stratosfeer? Dat zijn er maar weinigen die dat ook kunnen zeggen.
    Gefeliciteerd met het gave resultaat en suc6 met je volgende experimenten.

  39. Margo says:

    Wat super joh!! Ik blééf maar kijken! Een felicitatie waard!

  40. Gert-jan Bremer says:

    Tim, ongelofelijk gaaf zeg!! Knap gedaan hoor. Haha voor 220,- de ruimte in, da’s goedkopere dan de amerikanen ;-).
    Ben benieuwd naar je volgende expiriment.
