Can anyone identify this object
Topic by martian101 | last reply
Hello experts, I have this code which works so perfect while detecting square objects from images which are downloaded from internet. However, when I am taking the image of a square object from my webcam and processing, its not turning out to be as expected. I am suspecting, the reason could be due to the green and pink hues which are dominantly captured from webcam. The actual output which is being obtained is that there are squares distributed at random places. What do you all suggest? PS http://i49.tinypic.com/2lw8xw0_th.jpg here, only one circle should be there around the white circular object thats being held.

Just had this idea and would like to hear from someone with experience with concrete. Can I make an object - a concrete shape ( box) which which has inside full of styrofoam? I am thinking about the posibility to make staircase from concrete with styrofoam inside - the role of styrofoam is to make the the box lightweight.

On Instructables, contests have tended to had very limited specifications beyond a general theme they work to. I propose this trend be broken in favor of something a bit more actively competitive: hold contests where the objective is set and have people compete to meet that stated goal as set by the contest host. The parameters that entries would be judged upon would be laid out in the briefing, as would any material or cost limitations. Holding competitions in this manner would entice people to competitively build something to meet the requirement the host sets and to do their best to hone their project to succeed in the relevant parameters. I think this would be a nice change from the chaotic randomness of current contests where there isn't much competition among entries, besides wooing people for votes to win finalist positions.

The Gomboc is a "mono-monostatic" object -- a three-dimensional object that purely by dint of its geometry has only one possible way to balance upright.The challenge intrigued two scientists, Gabor Domokos and Peter Varkonyi, both of the Budapest University of Technology and Economics. They spent a few years doing the math, and it seemed as if a mono-monostatic object could, in fact, exist. They began looking to see if they could find a naturally occurring example; at one point, Domokos was so obsessed that he spent hours testing 2,000 pebbles on a beach to see if they could right themselves. (None could.)After several more years of scratching their heads, they finally hit upon a shape that looked promising. They designed it on a computer, and when it came back from the manufacturer, they nervously tipped it over, wondering if all their work would be for naught. Nope: the Gomboc performed perfectly. "It's a very nice mathematical problem because you can hold the proof in your hands, and it's quite beautiful," Varkonyi says.It's apparently similar to the shape of tortoise and beetle shells, explaining why these creatures can actually flip themselves back over.

Any suggestions for assembling found objects (cans, screws, bolts, etc.) robot sculptures? Welding, soldering (if so, wattage for the iron?), other? Total newbie, but I want to experiment.

Recieved this item as a challenge to figure out what it is. The drill bit in the picture comes out of the end of the tool and the tool itself has three adjustable jaws that are sharp at one end. The only other interesting marking is the drill bit has a hole drilled in the end of it.

Hello everyone, i'm working to build some home made toy, but I am missing one important piece. To find it at minimum price, I need to find an every day object that would contain a shaft with a driving ring. The ring would also need to be able to move along the shaft. Can anyone help me to find some idea ? where can I find it? I'm sure it must exists in plenty of objects, I just can't think of any.... thanks ! :)

I have a few questions regarding a project I'm working on. I need some terms so that I can look it up via Google. I have a map (picture) of a city that is printed on a wooden table. When I move an object directly over it I want to know the coordinates of the object on the map. And also the angle of the object on the map. I thought a sort of a scanner is the best solution. That recognizes the part which it scans (part of the map) and translate this to the coordinates and angle. Does somebody know how this technology is called (and maybe a few links to guide me in the right direction)? Or does somebody else has a better idea how this can me realised? Thanks in advance!

My husband and I just moved into a new house on 5 acres. While cleaning some of the 'back' yard, I found a small metal coke/beer shaped-type bottle. It is obvious to me that it is a promotional or key chain fob or similar object. It looks like it screws together in the middle top to bottom. That is the crucks, it is frozen closed so the curiosity in me is trying to find how to unscrew the item. Any suggestions?

Any idea what these are? I think they’re from a surveyor possibly around the 1950-60’s but not certain what they are. They’re appear to be made of plastic or lexan and don’t appear to have any optical qualities. The three pieces are concentric in size and have a goove on one side. They came in the leather pouch shown in the photo. Thanks in advance!

Hi people, My name is Cynthia and I need some help with Object-oriented programming. I have a project for school where I'am making a 2D platformer game with Unity. Where I have to make a base class and two child classes that inherits from it. I have to work with constructors, properties, etc . The problem is I kinda know what the constructors, properties etc do but I don't know how to put them together to make a game. Can someone help me, push me into the right direction cause now I don't know where to begin with. What I like to make is a Enemy base class with two sub classes (enemy 1 and enemy 2) or base class Item (sort of coins or power ups) with two sub classes (item 1 and item 2). If there is someone who can help I would be so grateful. (I program in C# and the game must be made in Unity). Sorry if this is not the right place for asking such a thing. Thanks Cynni

Hi,I love my technology and have attempted to build many small electronics projects with varying levels of success and completedness.I have an idea that I would love to put into action but having a lack of knowledge in ZigBee I wanted to put it to the community to see who else has a need and if anyone else has had any success with the aforementioned Hue system and a DIY ZigBee project of any kind.My idea comes from a need to make things simple for the family and guests in my home to use the Philips Hue system I have without having to re-wire the house. I would like to have a single push button that uses the ZigBee network with Hue that can do multiple things based on lengths of push and number of pushes etc. Much like the remotes can already. However I want to make it so you can put any kind of momentary push button on it.In New Zealand I use a very common style of switch plate made by a company called PDL. The plates have a variety of options and one of them being a modular system that has a push button available. There is even one that has a small LED on it.Having the ability to add a second module to my light switches that allows you to push the button for simple on/off functionality. Long press for dimming and multiple press for scenes or set brightnesses.Now i've coded for Arduino and used this on ESP modules but never done anything in the ZigBee space.Has anyone done something like this before?I'm not asking for anything to help me do this but rather pointers. I will continue to research this project and hopefully one day make something worthy of an instructable for all you kind folk out there! Happy building!

I found this object in an old area of Big Sur, California with my metal detector several years ago. It appears to be very old and has a small hole drilled through it. You can see writing/ markings on it but I have no idea which language it could be. It's not very thick. I'm not sure what it's made of either other than some type of metal. Any feedback would be greatly appreciated. Dave

See the screenshot. The message below (Type error: can't access dead object) appeared in the instructables tab after I accessed a forum topic in another tab. The pop-up completely jammed my browser - I could not close the pop-up (it popped back up instantly), and I could neither close the tab nor even close the browser through normal routes (corner-X, Alt-F4), all I got was a blink of the screen, a warning tone and the pop-up back. I had to shut down and start again.

Hi all, I was wondering if i could get any pointers on mixing concrete, I have gone through the concrete mixing instructables already and have not found anything suitable and hence I am asking her. I want to formulate an open recipe to make concrete objects like the ones in the following links, http://fancycrave.com/concrete-desk-accessories/ http://www.ledindon.com/en/objets-design/9029-stylo-plume-beton-arme.php http://www.designboom.com/design/concrete-rollerball-pen-by-22-design-studio-at-designboom-shop/ They are mostly small objects where the wall thicknesses are quite small (maybe a few mm). I think it will be interesting to see a DIY approach to making a concrete composition that is strong in small thicknesses, i think a lot of cool objects can be made from it . I have tried the normal concrete mix with cement and sand but i am not able to get it strong enough at those small thicknesses. Can anyone please some suggestions or advice on how to go about this ? Thanks in advance, please see attached files for some images taken from around the web, i do not own any of them.

Hello! Somehow a small 9mm steel BB found it's way into a piece of wooden outdoor furniture. I know how to repair wood, but I can't seem to get the BB out. I've tried digging it out with a small knife, but that only resulted in me damaging the piece further. Do any of you have any experience with this, or ideas on further courses of action? Anything is appreciated.

I get this when I go to edit my instructables "There's been a problem updating your Instructable [object Object] error Service Unavailable" I cannot edit my instructables becuase of this and I get the "updating" progress bar that does not go away unless I use ad-block plus to force remove the object. But this makes the edit page half rendered and any edits do not save. It happens in multiple web browsers. What could be causing this? Thanks.

So 2 parts to this question, one is what would it be called, the other, where would I find it. I am looking for a valve that would have 3 stems, for lack of a better term. One one end would be the source, another the output and the last would alternate between pulling from the source and pushing to the output. Any Googling tips? Not looking for anything industrial, simple small plastic valve would suffice.

Hello DIYers, I have a small square object (6cm x 6cm) that I must put in a mold, but how it's square, is possible put it in any position, but only 1 is the right one. The reference is a 5mm label in the top. I want detect if the object in the mold has the right position. Actually I have 5 different objects, the difference between them is the number in the label. My idea is use a Raspberry Pi + Pi Camera + openCV. There will be a collection of images for reference and the camera will be recording jpgs (maybe 1fps) and comparing with the images in the collection. There will be a red led lighting, but if the RPi detect the right object in the right position will light a green led. Maybe somebody knows a similar project? is possible with this hardware/software? some recommendation? For better idea, I'm attaching a mock-up
