IPTV Front-user Interface

The project is in the early stage, so if you have some interesting solutions we will be happy to increase you budget.

We need a program that will auto-start with linux and will be controllable with a remote controller. Good example is XBMC. Program will be run at machine similar to Acer Revo (1.6 GHz Atom, nvidia ION, 1(2) GB RAM). It must be able to receive streams from server (TV channels) and request a video-on-demand. That should be done with libVLC (Video LAN framework) and VLC player as video player.

So, we need 10-foot user interface that is neat, fast and safe (user will have only remote controller and must not be able to change settings). It should have menu with options: TV, video-on-demand and Internet (more about that after some time). It will be used in hotel rooms.

If you are interested in working with us and have good ideas, fell free to apply, we are looking forward to have a good cooperation with you.

Design Active Power Filter Using FFT Algorithm

This project requires a three-phase shunt active power filter based on DSP controller.The developed controller utilizes FFT algorithm to extract the reference signal from the load current, considering the phase-angle delay of each harmonic component.
The operation of the project must be verified through computer simulations with the user defined model in Matlab/Simulink.
A 9kVA hardware prototype was built and tested to confirm the simulation results. It is composed of a three-phase bridge inverter and a developed controller with DSP TMS320F2812. The active power filter is connected in shunt with the non-linear load, which is connected with the source of 380V. It can can operate well in the unbalanced load condition and voltage source distortion . The full-bridge inverter consists of three dual IGBTs with 1200V/100A rating, the switching frequency of inverter is 11 kHz.

Java Web-based Cron Scheduler GUI

I require a component to be developed for an existing web site (developed using Spring MVC and hosted on Tomcat) that allows a user to specify a cron schedule via a GUI. The website itself is a maven-based application so the new component will need to adhere to this.

I will provide the project framework containing skeleton classes/JSP/resources (including the pom.xml) as well as a wireframe outline of the interface I require.

The component will need to be developed using JSP and javascript, and the users submitted details need to be translated in the Spring controller class into a single string representing a valid cron schedule. Validation is also required for all entered fields with relevant error messages being displayed in a user-friendly format in the GUI. Upon successful submit a page should return showing the entered cron details in a human-readable format.

Working/filled out Eclipse project containing:
1) Implementation classes (comprising at least a controller and a validator), JSP and other necessary resources (eg Spring config file).
2) Working JUnit 4 test classes for the validator and controller as well as other implementation classes.
3) pom.xml file for the project (updated as required).

Proposed payment schedule:
2 milestone payments:
1) Delivery of JSP and controller consisting of a GUI allowing user to enter schedule particulars, and then upon submit capturing the data and converting into a single string representing the cron schedule. (75%) Unit test for the controller. Simple success page displayed upon successful submit containing user-friendly text format of the entered data (eg 0 * * * * ? should display as every minute in the success page).
2) Developing the validation around field values via a Validator implementation class and rendering errors in a user-friendly format on the GUI. Unit test for the Validator showing each element in the submitted data being validated including success and error paths for each.

Arduino Greenhouse Controller


I need someone skilled with the arduino microcontroller, both with the soldering part aswell as programming the controller and programming the interface on the computer via usb. Open source code is adviced for the various settings and options the controller will have, however the open source needs to be tweaked into a joint interface on the pc. I also wish to take part in the creation; but all this will be discussed when i find someone with the knowhow of the arduino. Communication preferrably with skype(text) after successful bid.

The controller will consist of :

– Ph measurement/control*
– Relay control (inductive loads aswell)
– Temprature/humidity sensor/control*
– Pc interface virtual construction kit for making connections between the functions, like synthedit(vst, link: , synthedit also provides a development kit that might be useful )
– And logging from all of the above.

*(all control is done via relays)

The choice of programming language for the pc interface is optional, however i would prefer c(++).

The price of this i am unsure of but the winning bid will also be offered further work, so thats why i set it as simple project, pm me and lets talk! 🙂

NES Controller Photoshopping With Multiple Image States

I would like you to take a photograph of an NES controller, and make multiple image states fro button presses.

In other words, take the image I have attached, and make versions where each button is pressed down, and not pressed down.

So, there needs to be an image for every possible button combination.

You need to have your own NES controller to take pictures of, unless you can photoshop it from a sample on the internet.

Please contact if you have any questions.

Thanks, and good luck on bidding!

Need Some Quick Magento Help

I have a Magento store and for some unknown reason, it has suddenly started throwing a "headers already sent" error. I added some items to the store last week and set up a coupon and everything worked fine. Today I set up another coupon and when I went to check the coupon, I started getting this error.

The store works just fine, up to the point that you go to add something to your basket. Then you get the error submission screen below. If you go back a page, the order page will reload and if you look up in the cart line you will see that the item has been added to your cart. If you go to your cart, there it is and the coupon works just fine. Its just when you adding any item to your cart that this screen comes up.

Conventional wisdom (Google) says that this is a php error and that there is probably a blank space in the referenced file. I have looked, downloaded into Emeditor and saved UTF-8 but the problem remains.

I did not open or make any changes to the referenced file when I was adding items to the store last week. Its a live store and I need to solve this asap.

Appreciate hearing from anyone that has the time and skill to make this right in the next couple of hours.


The error looks like this:

Cannot send headers; headers already sent in /home/xxxxxxxx/www/www/app/code/core/Mage/Catalog/Model/Resource/Eav/Mysql4/Product/Collection.php, line 1

Start/Stop My Home/Office Water Sprinklers From My IPad

I have researched a lot about this, I am not a programmer thats the only problem, exactly what i need is i want to start/Stop or see status of my Sprinklers at my home or office . The sprinkler is just an example to keep it simple.

What i have in mind is that we need to make a micro-controller that will have 10 inputs and 16 outputs (digital i/o)
and may be one or two analog I/O. And we need to connect this controller with ipad wired or wireless, to see the inputs on ipad as status and when i tap that btn or picture on ipad screen that will send output (signal) to the micro-controller , micro-controller will consist of relays that will give output to micro-controller output port so my sprinkler gets the on signal. and when there is smoke or fire alert a signal will be given to my micro-controller input port to my ipad and the alarm will sound and visual on ipad screen… to give u exact idea what am looking for u can go to and see what they are doing if u understand that u can make this, or go and see what yelp engineers did with their ipad and Beer Keg.

if u need any help on understanding this project you can send me msg anytime. I will pay your your hard work + material cost

only serious people who know about electronic micro-controller and ipad programing should contact me, please dont waste my time if u dnt know anything.

Google Search And Nav Controllers Needed For Yii Framework

Im in the middle of a site redesign.

We were hoping to have the site finished by September 5th for a book campaign that hits Sept 8th. Unfortunately we just lost one of our main developers.

What Im hoping to find is an expert in the PHP Yii Framework (see link below) who could help develop a few controllers for us. You would *not* be responsible for an entire site development, just a few controllers/widgets within the site. A pretty simple, paying gig.

Basically you and I would have about 7-12 days for the work.

Here are the pieces wed like help with (contact me if you could help with ANY of these):

1. Google Search Controller:
We have a paid Google private search account and need to wire up a controller to make the required Web services calls, process the xml, etc. The CSS design layout is finished. We just need the nuts and bolts and wiring assembled into a Yii controller to make it run. (see screen shot) Could be as simple as what you see here ( ) though Im not sure why this fellow is using Googles AJAX api for these calls.

2. Nav Controller (or widget?):
Our main left-column nav changes depending on which section of the site youre in. Wed also like to highlight the page the person is currently on within the current menu. Theres also a series of horizontal dropdown menus that have pretty much the same links as those that appear in the left nav. Last but not least theres the links in the footer. Not all of this needs to go into one controller (for example, the footer links could just go into the main layout), but it would be nice to get as much as possible bundled into it. The way Im thinking of going about it is to have the section controller for the site (store, about us, free content, etc.) set which section nav to render, then each controller action would specify which link within the menu to highlight as a "You are here" designator. Maybe something like this could be used: ( ) (see attached screenshot for look & feel of our design)

3. Breadcrumbs: [If time allows]
Help define the breadcrumb scheme — possibly tie into the Nav controller/widget if possible.

4. Pagination: [If time allows]
Help setup pagination for our content sections.

The CSS for the layouts is finished. We just need help getting the controllers built and integrated into the site application. I have a screenshot I can send you showing all the menus and the layout for our search results page.

If youre interested please reply back. Im in southern Oregon, by the way — thats on the west coast of the U.S. Would be nice to see examples of your work if possible. Im aiming to meet with our Director Wednesday night to go over the approximate budget for this work, so I need bids from you ASAP.

Sorry for the tight scheduling. . . ahh the joys of Web development!

PC Inventory Software

I need a simple application developed that will reside on the taskbar and submitePC Inventory such as current ip address, up time, User information (Name, Address, Phone Number, etc), Computer Name, Domain, as well as Hardware Information such as: BIOS CPU Cache Memory and Phyiscal Memory Harddisk and Logical Disk DVD / CD-Rom, Floppy Drive and Tape Drive Motherboard Monitor Display Card, Sound Card, NetworkAdapter and Modem Keyboard and Pointing Device BUS and System Slot 1394 Controller, IDE Controller, USB Controller, SCSI Controller and PCMCIA Controller And software information such as: Window OS Installed Softwares Microsoft Packs / Update / Security Update / Hotfix Drivers, Running services The application will run preferebly as a service therefore it is harder to remove. The user information will be entered through a simple interface that opens when you right click on the taskbar icon and select "user info" There will also be a about menu when right clicked. The server / url to send the information as well as all the information specified in the About menu will be specified in a INI file. That way making it easy for us to deploy for multiple clients. The Client will update the server at each bootup as well as hourly intervals or whatever we specifiy in the ini. I will provide the taskbar icon. The server will be MySQL we will need a script or something to make the database the way it needs to be made. Also the data must have a simple web interface with user / pass auth. The interface must have a logo and maybe some information then there will be the data for the computers I want to be able to select how many records to see at each time including the most recently active computers. We must be able to sort by First Name, Last Name, IP, etc. Just as a simple form filter to put in order. Also there must be a printable view of a "report" like we may want to print a report with all the computers with Windows XP so all we need to do is sort / filter all the xp computers and print and it should print in a printable view such as gmail does when printing. There will be future developments / add on oppertunities for the winning coder. Please contact me so that we can discuss full details

Flash Audio Controller For Pdf Document

I need to insert audio files triggered by an audio controller/player into 5 pdf documents.

I need the following controls:
play, pause, return to start, and a progress bar so the user can move around with the audio clip.

I tried using ready-made mp3-swf convertors which worked fine except that when I placed the swf into the pdf using Acrobat Pro they did not display correctly until the audio was triggered. They also looked a little unrefined. You will receive this as a guide for size etc.

There are 5 separate projects over the next month. Each project has around 5 pages with the same controller (visually) accessing different audio clips approx 3 minutes long on each page.

I will supply separate mp3 clips and pdf documents. You will supply me with separate swf files plus the pdfs with the clips inserted.

Please quote separately for the Flash work and the pdf insertion work.

In summary:
Design/modify one Flash audio controller.
Link it to around 25 audio clips in pdf documents.
Return swfs and pdfs.
Work to be delivered as 5 separate projects over next month.

Thank you.
