    Need co2 levels displayed on lcd in real time in percent. For example 40,000 ppm will be displayed as 4.00%. It will also show the valve status (open or closed) Buttons on LCD will control the co2 threshold. Once the co2 reaches the threshold the valve goes off. Below the threshold the valve is open. Threshold is set in percent as well. So if set at 4% the valve will stay open until it reaches 4% and then close.Let me know if you have further clarifications.

    Hello campaigner,Our project is based on a Raspberry Pi.The device needs to allow a user to interact with a Screen, Flash Drive and Raspberry Pi.In Simplicity:Phase 1:A user needs to place a "media" file (Video or Image) in a predefined directory on a Flash drive. When the Flash drive is inserted in to the Pi, the media should be automatically loaded and rendered to the screen. Phase 2: ONLY ONCE PHASE 1 is COMPLETE - includes it"s own budgetA User should be given a GUI to this process and be able to schedule the media file to play / stop between a timestamped period. In the above, lea-way should be made to trigger a switch mechanism (which will be connected to the PI"s GPIO pins) that controlls a light.

    Hello,I am looking for a simple application that, using the OpenNI toolkit (or using the Microsoft provided ones, if it is simplier), have a simple method to record a user"s movements as a "base", then allows a second user to be "recorded" while comparing the second users movements against the first one. More specifically, we are looking for what is described in the PDF located here - http://www1bpt.bridgeport.edu/~jelee/courses/CS550_F13/Paper/2.Dancer%20Performance.pdf as the Data Acquisition Software GUI (Figure 2). As the screenshot there shows, there is a base model (which was prerecorded), and a new model that is compared against the baseline to determine the relative position of joints between the two models. The screenshot shows a rather intensive comparison and for this stage in the project we are just looking for a more crude comparison based on relative comparison (and highlights the points in a given movement where the two recordings are significantly out of sync). It is important that the speed is not important and that the comparison just compares movements, not timing. Any open source toolkit is welcome as long as it is mentioned and clearly indicated. All code must pass StyleCop (http://stylecop.codeplex.com/) review, be well documented, and otherwise follow the guidelines located here - https://csharpguidelines.codeplex.com. Code should be C# unless otherwise agreed.

    I am using a type of real time clock alongside an arduino UNO. I have found some old code but it"s narrative and effectiveness leaves a lot to be desired. I need someone who is proficient in reading schematics for IC pinouts and the setting up of legacy IC"s. The end goal is for two separate sketches that will enable me to program/initialise the two types of RTC. These being Texas instruments BQ3285p and BQ4845p. The main issue at the moment is initialising the oscillator as this appears to have been omitted in the original code and this needs to be written in as according to the PDF datasheets this needs to be done with new chips. The schematic with the code is poor to say the least, so some forensic deciphering of the pin outs and cross referenced with the code will be necessary. At a later stage for those with experience of using Eagle, I will require a design for a breakout board using either or both chips for starters. Where successful there are other RTCS which could be useful and this could entail similar diagnostic work/code writing. At the moment I have several of the chips and have got the 3285 working but the stumbling block is the initialising of the oscillator, I am sure this is a software i.e. code issue.SKILLS required, electronic engineering fault finding, conversant with arduino code, ideally exposure to using rtcs and microcontrollers desirable in a commercial setting and experience using legacy IC"s.

    I run a video gaming centre equipped with 32 inches plasma TV, Playstation 2 and 3 and Xbox 360. I want someone to write me a program that would enable a gamer to purchase a ticket for a number of minutes, input the code on the screen and then he or she can play the game. If the gamer pays for 15 minutes or what ever time he or she purchased and the time is exhausted, the game would close up. The codes for each minutes can only be printed by the administrator as this should help me with accountability and monitoring sales. An example of what I want is used at my cybercafe and we use the timer called Gocybertix (see website http://www.gocybetix.com/defaultx.asp .), unfortunately the timer only works on windows xp and I cannot use this program on my video game consoles or TV I am hoping someone can write a similar program for my gaming centreThanks

    Hi,I would like to find a designer to help me design a mechanism for a special simple spice mill, get a 3D model, and print it using a 3D printer.The idea:I would like to have a tube with diameter of around 2cm. Using servomotor (placed on top of the tubex), it should throw out a specific constant volume of spice for each full cycle made by the servomotor. This volume should be what is equivalent to quarter gram of mashed pepper. The spice should be already grounded.The challenge:Getting out the same constant volume is very important and precision is very important in this project.The mechanical movement should be done using servomotor and should be as simple as possible.The deliverables:1. Very preliminary design of the tube, the mechanical movement to release the spice, a short describtion of how it should work. We make some modification and proceed to next step2. First version of the full design, we could make some changes until we agree fully on the design3. 3D print of the product, test it and send me a video of it working. (servo motor is not essential here, a hand movement is acceptable). I will pay for the printing of the product. 4. Deliver the 3D model in acceptable 3D file format.

    I need to build for personal use, a simple small program to obfuscate text in a text file with a certain pattern. The program can be written in FreePascal, FreeBasic, C# (.NET) or AutoIt. It can either be command-line or with a simple window.The freelancer would propose one of the four languages to write the program, and what they would use to do it in that language. Preferably, the program would use some REGEX functions or library.Here"s a work flow description:1) The program would make two passes through a text file. 2) The first pass through the text file gets an UNIQUE list of all words matching a "prefix" list (or a simple prefix file) that the user can pre-define as parameters for the program. Such prefix as ABC_ xyz~ or any combination of characters. Words are defined by characters delimited by a character or characters (such as , ; . or ;;; ?? //] ) as parameters for the program. So, take for example, there would be text such as: ABC_sometextword, NotIncluded, ABC_sometextword.notinclude ABC_someothertextword SomeOtherWords xyz~text ABC_sometextword; Given the prefix would be: ABC_ xyz~ (and must be attached as part of the word) Given the delimiters are: , ; . The unique word list would be: ABC_sometextword ABC_someothertextword xyz~textThe delimiters are not included in the word itself to obtain the unique word. Also, there should be a parameter that allows us to select if the prefixes are case sensitive or not.3) Then we create a replacement random text for each unique words. The random text would be text with characters in the set (A..Z, a..z, 0..9), but the first letter must be (A..Z or a..z). We can also set the maximum length of the random text generated, and the program would randomize the length of the text as well.ABC_sometextword = weJDKLIke0rABC_someothertextword = Jjd74kwexyz~text = ieo823j4) The second pass through the ext file replaces the unique words with the matching random text.The output of the example would be what is found belowweJDKLIke0r, NotIncluded, weJDKLIke0r.notincludeABC_someothertextword SomeOtherWords ieo823j weJDKLIke0r;5) We would skip sections by the user defining a starting and ending block of characters. For example, we can define start ignore section with this text "//[[" and end section "//]]" //[[ Do not include this section //]]In the above case, the entire block is ignore for both text passes.6) We can run a wildcard in a folder to process all files, and the output will add an extra extension defined by the user, such as .outobfuscate.exe *.txt .out --someparameters
