Fabelier | a *Lab to create new things. LED series parallel array wizard. CKTouch [ cktouch.fr.nf : Redirection par AZOTE.ORG ] [HOW TO] Automate hid driver + CCV in background. Hi guys. For few days I tried messing with the sources of both ccv and hid driver but had no luck. My goal was to get hid driver automated and ccv as well working in the background. I tried many methods and this seems to be working the best. I got the idea from cktouch’s method so, some credit to you, which can be found here: If anyone wants the hiddriver, please refer here : and how to install it please refer here: In the attachment there will be 3-5 files, which i will show how to use in the video below. Edit: I have updated ccv.exe where the path is not specified, so it no longer has to be in “c:\multitouch\”, it just has to be in the same folder as community core vision. Please let me know if i missed anything. Here is the source for ccv.exe for anyone that is interested.

Thanks. Galerie de Tiago Serra. FTIR Multitouch and Display Device - Experiments with Processing, OSC - Thomas M. Brand. Materials: - arylic plate, size that is ok for you. make it comaptible to the screensize you will use, so 4:3, 16:9 or so. i took a 640 * 480 * 10 mm plate. Be careful when reading the specs on the box of cameras standing on the shelf. for instance 30 fps does not mean automatically that this framerate is available in max resolution. some cameras even seem to duplicate frames to have bigger framerates (??). -optional alternative lens to the one that is normally deliverd along with the camera. take one with a suited focal lenght and F-number for target setup. [Focal Length and Aperture Explained for the Photography Novice] normally optional lenses are sold at the same place as the camera but there are a lot of e-bayers selling different styles of them.

-optional IR bandpass filter [ [Tuto] Un bureau tactile | I'm not Geek. Comment avoir une surface tactile innovante sur une table toute simple ? Voici un tuto complet pour vivre dans un futur tactile qui n’appartient plus à la science-fiction. Comment ça marche ? Très simple, une camera, modifiée pour ne voir que la lumière infrarouge, filme une surface. Cette surface peut être un écran ou une projection, la caméra ne voyant pas le spectre visible pour les humains ne voit donc que l’infrarouge. Un logiciel en open source multiplatforme va convertir le point blanc crée par le stylet pour en faire une information exploitable par un logiciel qui va en faire une donnée tactile pour l’OS et donc générer une souris ou un zoom. Le projecteur Un projecteur et un miroir peut être une bonne solution suivant le placement de celui-ci, l’image peut aussi être projetée directement sur un mur, le tout étant de ne pas trop gêner la projection avec ses mains et le reste du corps, la caméra doit aussi pouvoir voir la totalité de la projection.

La caméra Le stylet infrarouge. Multi Stuff. Custom Laser mounts. 24" LLP LCD Project, based on Ikea’s Expedit coffee table. WIP. After mounting the lasers, it looks something like this: I’m really happy with the small footprint the “calibration mechanism” have. I mounted the main circuit board to the inner side of the side board. You can see the extended cable on the top left, running from the input board to the main circuit board, and the cables at the bottom are from the backlight.

The backlight sits at the bottom of the table. You can see the extended cables here too. I connected all the lasers in parallel, and to a USB cable. I used clear tape to hold the diffuser films from the LCD to the bottom of the plexi: You can see that the holes for the lasers aren’t so pretty on this side.. That’s all for the moment. Precision Laser Mount, screw adjustment : : Low cost opto-mechanical components : Opto-mechanics.co.uk from ORLIN Technologies Ltd.

Laser Mount / Adjustment Tool. Laser mount - yet another one ;o) Thanks for the encouragement! Don’t plan on adding sides but there’s no laser guard yet - I don’t fancy fried eyes. Has anyone done any real tests on how intense the diffused light from the 25mw lasers actually is? It’s not the best welding job in the world but it’s easy to grind off bad welds :o) It’s made from 20mm box steel and actually really light weight and very portable - cost £20.

I’m guessing it would be pretty straightforward for a real welder to do if you gave them some plans. I just marked the angles and cut through 3 sides of the metal - leaving the outside intact. Then just bend it and check the angles. ZAP, ZAP, ZAP - drill, drill - lick of paint - job done! I found a handy cad plugin for Illustrator that gives you dimensions and angles - Hot Door Cadtools . The finished frame is far from being accurate to .1 of a degree ;o) The result is something like this - How to build a simple screw-adjustable laser mount. I need to be able to disassemble my LLP table to transport it, so the worry of laser aligment was bugging me. I thought that using clay would not allow me fine adjustments to get my laser angles 100% correct. I came up with a simple mount that allows you to adjust the up/down pitch of the laser very finely using two screws.

The trick is in using some squashy foam underneath the mount to clamp the lasers against. Parts: * Aluminium right angle extrusion (10mm x 10mm x 1mm) * Machine screws (M3 for fine pitched thread, long enough to go through your tabletop surface + 10mm) * Washers * Draft excluding foam strip - Cut the aluminium into 60mm long strips. - Cut a 10mm piece out of one end of each mount (I did each end for better access to adjuster screws). - Drill a hole to fit the machine screw at each end of the longest part of the mount. - Position the laser on the mount, allowing room for the machine screws and washers. . - Drill the tabletop where the lasers will be mounted.

MindFlux. Triangle Calculator. Instructions Enter values three of the six sides and angles of the triangle and the other three values will be computed. The number of significant values entered will determine the number of significant figures in the results. Frequently Asked Questions Q: I like your triangles, especially the ones that have interior angles not summing to 180 degrees. A: Because each of the sides you entered has so few significant figures, the angles are all rounded to come out to 80, 80, and 30 (each with one significant figure).

These LEDs were made popular by the recent 10x3 meter LED-LP wall installation by Gabriel Giacomini which you can see in the videos below.

They used these LEDs around all the sides of the screens. LED-LP is similar to LLP where it creates a plane of light just over the touch surface and the blobs are created when an object breaks the beam. This is a much safer way to make large installations than using lasers. As you can see bolded in the specifications below, the beam angle is very very narrow at 6 degrees, making these the most ideal LEDs for LED-LP. It is recommended that you space the LEDs as close together as possible to create less of a grid effect as the ideal setup is a continuous plane of light over the touch surface.

Prototyping Laser Mount for the LLP Screen « ㅁ. An early prototyping laser mount designed to fit to our frame design, with controls to accurately level the laser on the LLP multitouch surface. Like this: Like Loading... About Suk Kyoung Choi artist / researcher. Laser Light Plane Illumination (LLP)

From NUI Group Community Wiki Overview Infrared light from a laser(s) is shined just above the surface. The laser plane of light is about 1mm thick and is positioned right above the surface, when the finger just touches it, it will hit the tip of the finger which will register as a IR blob. LLP Parts List Clear, flat surface (Glass, Acrylic, Polycarbonate, Plexiglass, etc.) Laser Safety According to information obtained from Aixiz (laser supplier) through Sniperchang, their 780 5mw lasers would be class IIIR (used to be known as IIIA)and their 780 10mw lasers are class IIIB . Class 3B lasers safety information from Wikipedia is the following: A Class 3B laser is hazardous if the eye is exposed directly, but diffuse reflections such as from paper or other matte surfaces are not harmful. No one on the NUI Group will be responsible for any injury or damage to anybody caused by a misuse of these IR laser modules.Please use these IR laser modules in a safe and responsible manner!

References. Labs » Rear-Projection TV Turned into a Multi-touch Display. Continuing our multi-touch research, we’ve been working on turning an off-the-shelf rear projection TV into a multi-touch display. This screen has the best width-to-depth ratio of any multitouch system (67″ diagonal viewing area and only 16″ deep). This is also the first example of hacking a multi-touch system into an off-the-shelf television. The system we settled on uses very few additional components and could potentially be applied to any rear-projection TV. The display is only 16″ deep Setup and Theory The system has four IR lasers mounted in the corners. Below, we’ve posted as much information as we have to enable you to build your own version! Software tbeta for multi-cameras We got in contact with the people at NUI group and offered to work on multi-camera support for their release of tbeta. NUI group will be releasing source and a new project management system for developing various NUI Group projects (including tbeta) within the next two weeks on their website.

Case Mod Due to how much a replacement lens may stick out from the camera, the back-door of the GoPro case may need to have its foam scrapped off to allow the door to properly shut.

By scrapping the foam off it gives about 1/8″ more room for the lens to stick out. All buttons should still work. We have not pressure tested the camera setups needing a “case mod” so please do so if you plan on submersing your setup. Dust Ring The stock lenses have a much larger terminating diameter than most of the lens replacements we offer, so the small space around the lens surround can allow dust in depending on your filming environment. As with any of our products, please Contact Us if you have any questions. PS3 Eye Camera Band Pass Filter Insertion. To add a filter to the PS3 Eye camera, follow the video below on how to remove the stock infrared blocking filter: Once that is done. Make sure the the plastic around the removed filter is flat and level like in this pic: Simply choose which filter you need: 780nm850nm880nm940nm Blow out the lens and make sure there are no pieces of loose plastic.

You should hold it up and look at it to make sure it is level and in far enough: Then screw it back onto the PS3 Eye camera board, making extra sure not to tighten it too much for you will break the glass over the sensor if you do. When testing the camera once the lens is on but not back into the original plastic camera body, light will be able to hit the sensor from the sides so your image from the camera will sort of appear washed out. Now assemble the camera back together if you desire too, and when you put the circuit board back into the front piece of plastic, make sure not to screw it down too much.
