    I need an application to Raspberry Pi that takes a picture using a usb camera, preference with Logitech C920. The camera application needs to have the following features: take the picture in square format, timer to take a picture (and show the timer in the screen. Ex: 5,4,3,2,1), show the picture in the screen with the words SALVAR (save in portuguese) or APAGAR (delete in portuguese). After this choice is made, the camera is ready to take another picture. Auto syncronize the picture folder with any folder in a computer in the same network. I need 3 different keys of the keyboard to perform the 3 tasks (take the picture, save and delete).

    Hi,Thanks for looking! I"m not proficient with all of the terms used in this field so please be patient while I describe what I need. I need somebody who is efficient with C programming or better yet, someone who has experience with Arduino libraries to program a Arduino USB micro-controller with an lcd interface attached. The controller will output a 4 digit code to a text file (or input field) on the computer. It will also output this same code simultaneously to an lcd screen that"s attached to the micro-controller itself. The controller will start at 0000 and run until it reaches 9999. There are a few other simple conditions that need to be implemented such as:Hit enter after entering the 4 digit code. Wait 16 seconds until outputting the next code.Begin automatically a short while after it has been plugged in to the computer.I have the majority of the code ready for a teensy 3.0 but need somebody to tweak it so that we can output it to the lcd screen.I will purchase the Arduino and lcd attachment after consulting you and seeking your advice on the best one to purchase and await the code to implement it. If it"s more suitable for me to send you the device, then I may be willing to do that too. Thanks for viewing.

    I have created/written a picture framing website where the user can select various different picture framing elements.All the different elements are passed to a javascript function that uses jQuery to update the src of visual image of the picture frame/mount.The image src will be somthing along the lines of ....visualisation.php?project=imageWidth|imageHeight|frameID|frameWidth|topMountColour|topMountWidth|topMountCoreColour|bottomMountColour|bottomMountWidth|bottomMountCoreColourI can create the src URL.What I need is the visualisation script that creates an image from the given parameters. Not sure if this can be created using the HTML5 Canvas tag?? or if it would need to be a php script.Getting the proportion correct based on the image width/height, frame width and mount widths is essential.The image must update client side, and be a smooth transition, i.e. no delay as the parameters are updated.

    This proof of concept is intended for my shooting club - we plan to install cameras on the range for:a) livestreaming of the targetb) archiving shots for our membersc) scoringThe camera will capture a live stream and after triggered an event (will be a soundsensor) a microcomputer like a raspberry pi or even a pc will execute the application as follows below - the application then should either return or write out some data with informationFor this proof of concept the following code should be written/the code should perform the following:After executing a commandline like "java executeable.jar image1.jpg image2.jpg" the application should open both images and compare them for changes (shots). If one or more shots are detected the application should return their position as a vector start from the target(NOT necasary image center).The target can be preconfigured (in this PoC hardcoded for one specific target eg. Rapid Fire Pistol - - where the bullseye has an diameter of 5cm, followed by a score 10 ring of 2,5cm, every further ring 9 to 5 has 5cm again. - but be aware that there are other shooting targets out there with one or more circles on it, or even eliptic, square targets with differenct colors - in the full versions you can preselect them - take a look at to get an idea about it - The diameter of the shot itself varies regarding the ammunition from caliber .22 (0,55cm diameter) up to .50 (1,27cm) but can vary slightly regarding the used bullet (full metal jacket, hollow point, wadecutter). Also target patches are used (the circle black or white patches used to cover the shoot of the last rounds) - so a shot at a patch might look a bit different because of the border doesn"t produces a clean hole.Also it"s not 100% sure that the target or at least the filming position won"t change slighty during wind etc.The angle might be a bit off, cause compared to the attached photos which where made by a smartphone camera, the livestreaming camera has to be in some safe location filming the target from the side/top.Also light conditions might change slightly during the event.If you need further testphotos (will try to make some with the camera installed on the range) - please tell, I will try to figure a way outIf you have further suggestions, don"t be shy and ask them - at this stage it"s far away from being a finished project/and you may also get follow up projects based on this one ;)

    First I would like to say the project would require in depth knowledge in Arduino programming as well as other programming and engineering as well as some botany knowledge but if you are interested in taking on the challenge. The project should be based on the arduino platform it should should be capable of taking multiple measurements with sensors Such as Soil humidity, Water temperature, PH levels, CO2 levels and also be capable of setting and controlling lighting, watering system and temperature.The most important part is recording the different measurements the sensors also setting and controlling the lighting fixture of the garden. Ideally for the finished product before going out to the public as a commercial product it would need to be able to send the information to a mobile device or computer where there would need to be a program that would need to be programmed to record the different information collected. Ideally there would be a graphical interface where it could create charts and be able to adjust and set different settings in the garden remotely. Also the possibility a second part of the project providing a webcam inside the garden with live feed to the program.

    In the GUI environment of Raspberry Pi (with Raspian Linux), I have added and successfully run a python wordcloud script that takes some hard-coded text and generates a corresponding wordcloud as a graphic file. I"m not familiar with how to use the existing pygame GUI library, looking for someone who is and can easily modify the existing code to divide screen between text entry area and graphic display area, prompt for/accept/use keyboard input (instead of current hard-coded text) as input to program, then display the wordcloud graphic (either by changing commands that currently draw the graphic file so they draw to the screen, or by displaying the graphic file that the current script generates).
