    Phase 1 : Wrapping StationSelections from a) Potentiometer Buttons or b) a Touchscreen;( if potentiometer buttons are used than the selections must be seen from a LCD ) Selections are as follows ;a - rpmb - accelerationc - turn times ( selection from 3-4-5-6-7 times 360 degrees )d - deceleration After selections made;Scenario ; A start button is pushed by an operator and software runs ;A motor accelerates and turns for 3 or 4 or 5 or 6 ... times( whatever selected before ) in 4-6 seconds ( this is also selected before from the touchscreen ) ( here you can calculate the needed rpm ) and stops.This is counts as "1 cycle". There will be around 2000 cycles at 8 hours. Selection of Motor ;You must guide me to find the appropriate motorSo motor runs for 4-6 seconds, rests for 10 seconds, for 2000 cycles at 8 hours, and will run for days and days.Overheating, cooling fan, etc must be monitored by the software.Software Options :- Must be like open source, and be on Arduino , so that we add options in the future at other phases.- Must have options to adjust the rpm, acceleration, turn times of motor- Sensor for temperature of motor ( in case overheating )- Cooling fan speed- Software will be written for arduino so i can check at my arduino board myself.You will guide me successfully , so we will proceed to second phase hopefully,Phase 2 : Operator Based DatabaseDifferent users will use “Wrapping Station”. I think of giving rf-id " s to operators and before the work she will introduce herself to system.To compare and for statistics, our software will keeps data of cycles and operators and health of the motor.Datas like : - Operator 1 started at 08:00 am. logged out at 1725 cycles Operator 2 started at 08:11 am. logged out at 2000 cycles - A logger for the health of the motor chosen at Phase1 ( how many hour worked, how the heat deviated, is cooling fan running properly etc )- The Wrapping station will send these data to a central laptop via wi-fi and a database will be kept at this laptop.Phase 3 : Transition from Arduino to Pcb and Power SupplyAfter the success of Phase 1 and 2 , A unique Pcb will be madeIf not achieved at Phase1 or Phase2 "Touchscreen" will be applied.At Phase3 also we will solve these :Incase of electrical shortages, a ) Data stored on Arduino not to get lost , a battery to keep the software aliveb ) A battery will implemented to system to continue wrapping ( software upgrades if necessary ) Since no big torque needed , for shortages like 1-2 hours reserve battery will be sufficient.So thats it.Hope this will help.

    when the car starts running, the client receives a confirmation SMS that it is running now. If this is illegal operation or any intruders try to run the car, the owner can send SMS to switch off the car. Afterwards, the system will check the mobile number for received message, to confirm that the phone number could access the security system; if the phone number is legal the system will turn off the car. If the owner needs to track the vehicle, he/she have to send SMS contains special code, after that he/she will receive a SMS containing the GPS coordinates of the car, the SMS updating its content every predetermined period. Also the car owner can connect another GSM modem with laptop to track the vehicle immediately using Google Earth.

    I need you to develop a software program that will be integrated into a website. This software program must be usable from the website itself. The website will act as the portal to which users can use the software. The software must do the following functions:1.Scan the internet to search for online sweepstakes.2.Identify the online sweepstakes that are applicable.3.Automatically apply for said sweepstakes using the information previously provided by the user.4.Provide a list of successfully applied online sweepstakes. 5.Additionally, the software must allow the administrator to limit the amount of sweepstakes automatically applied for the user. What this means is that if the administrator wants to limit the number of sweepstakes the user gets applied for to 20 sweepstakes per month, they must have the ability to do so. 6.There will be 3 different plans for which the user can sign up for. The free plan allows for users to qualify for 30 free sweepstake signups per month. The 2nd plan allows for 100 sweepstake signups per month. The 3rd plan allows for 300 sweepstake signups per month. The software must be able to accommodate these numbers. 7.The sweepstake entry process must appear as though the applicants are applying manually. This is so that they are not detected and disqualified from the sweepstake in the event that the rules stipulate that the user must enter his information in manually. 8.Examples of websites that do similar services to what I want: & this program must look for online sweepstakes, find ones that it can apply for automatically, auto-fill the user’s information into the application, and complete the application process for the user so that he is automatically entered to win in the sweepstake. The goal of this software is to allow the user to apply for hundreds/thousands of online sweepstakes without having to do so manually. The software should take most of the laborious work out of applying for online sweepstakes. The manner in which you complete the application process is up to you. If it is too difficult to create an automated process for which the sweepstake entry forms can be completed, another option would be to create a tool that will allow me to manually identify input boxes for which user information would need to be inserted. This method would be similar to that of SeNuke’s link building wizard tool. That is the best example I can give of what I am looking for, for the second option. The second part of this project is the website itself. I would like the website to be made using wordpress. I would like the website to be intuitive and interactive. The website itself must have a modern look and feel to it. I do not want the website to have a web 1.0 look to it. I do not want the graphics to be static and non-interactive. Other than that I am not too strict on how the website looks and feels though it must look professional. You may use your creative liberty to make the website.
