    ** REPOSTING THIS JOB, WITH A GREATER FOCUS ON THE ELECTRONICS DESIGN AS OPPOSED TO FORM FACTOR**I"m looking for someone to design an battery-powered array of bright white LED lights (or a single, powerful LED), with the end goal of the electronics fitting in a casing (which I will build based on the electronics) approximately half the dimensions of an iPhone, along with a wireless remote control on/off switch (herein referred to as the "Device").The Device should be bright enough to be seen clearly from approximately 50 to 75 meters away in dark conditions. The Device will be activated (i.e. turned on and off) via the remote control, with the default switch position being off. The remote control should be approximately the dimensions of an iPod Shuffle (w:4cm x H:4cm x D:0.5cm), with a single, large button on the front, and a tiny, red LED light in the corner to indicate that the button is active. When a user holds down the button on the remote, the light/lights will turn on, and when the button is released, the light/lights turn off (i.e. the lights only come on while the button is being held down by the user, but they cannot remain on without this continuous pressure). The remote and light array should be able to operate wirelessly within a range of approximately 7.5 meters. The batteries should be replaceable and of a type easily available, but long lasting (maybe something like a watch battery, but I"m open to suggestions).Ideally you"d provide an electronics design/schematic which I could take to a manufacturer, plus have you build a working unit that I can test to see if it operates correctly. The design of the board and lights should fit into the dimensions I outline above (I will work on the plastic casing after I have the electronics done). This should be a very simple circuit to build, so the schematic should be easy to understand.I will also need to consult with you on material costs. Ideally you could present a few different material options and I choose which group of parts makes the most sense for my needs vs. cost to build (e.g. multiple weaker LEDs vs. a single powerful one).I can provide detailed drawings of the intended design to whoever this project is awarded to, and help fill in any missing details on how this Device should look and operate.

    I have several (up to 12) instruments for measuring flow, they produce pulses related to the amount of flow. Using Aduino one I"ll like to have an Arduino code listing on how to count and add up individually these 12 amount of pulses on a long period of time (weekly or monthly) then been able to transfer these 12 totals to a PC. I will later analyze and apply constants to have actual measurements. I need this to be measure constantly and also to have an additional variable with individual measure during a period of time (3 or 4 o"clock in the morning, to be selected and programmed) so I can have the amount of pulses during this specific period of time in addition to the amount of monthly or weekly pulses per instrument.As a second phase I"ll like to add a SIM card and if necessary a SD memory card and transmit these totals via 3G

    Required to implement an electronic safe lock using the Atmega32A microcontroller. Using an Atmel STK500 development board, a 16×2 LCD panel, a 4×3numeric keypad, and a solenoid.Fundamental operation of the safe is as follow: -At start up, the safe is unlocked,-And the user can start using the safe. -The user will key in a 4-digit number of their choice, which is the password, and lock the safe using the “*” key. -To unlock the safe, the user must key in the password he/she used to lock the safe and press the “*” key to unlock. - During the locking and unlocking process, the solenoid will actuate accordingly. -The safe will detect three consecutive wrong password entered and will toggle one of the LED on the STK500 board or displaying an error message on the LCD panel. -After the three consecutive wrong passwords enter detected, the safe will be permanently locked. Hence the user’s stored password will no longer effective after this point. When the safe is in the permanent locked state, an admin/master password is needed to unlock the safe.

    Hi, We"re searching for people/company who can make a project in Arduino.We need something like a people counter machine. It has to count the people inside of a room and send that data to a MySQL database by wifi. The counting method could be anything... with IR sensors, with cameras, detecting the mobile connections or wifi, or 3G connectios around, with ZigBee, Xbee, whatever...We don"t need the system to be very accurate but we want minimum error. The budget can be negotiated. Thank you for your attention.

    I am an avid fantasy football player. During the NFL season for 16 weeks starting from Sept 4, there will be changes to the players on my approximately 80 teams, and these changes will occur a few times a week. I would like to send you the reports of the changes and then you can update the excel spreadsheet with the same. I would guess that you will make 6 changes per team per week (at different times). The biggest work would be typically required Wednesday and Friday evening"s around 11 pm EST.. That"s when I could send you the reports of the changes made. You would read the report, find my team"s changes, and then update my team on the excel spreadsheet. The keys to success will be (1) spelling players" names correctly, (2) making changes to the correct players/teams in the excel spreadsheet, and (3) timely turn around. There will be fewer changes as the season goes on and down to 3 per team or less the final 3 weeks. There will also be a few tables to refresh.

    ok - i need to use some existing sensors in an unorthodox manner to create a much needed automation solution ... id do it myself but the hours i could spend researching are better off served by using a competent programmer .. i am absolutely certain of the manner in which this setup will function .. but i need somebody to interpret my design and get it done fast .. I"m not rich .. but i will offer stakes in the final product as well as some money .. as this really is going to be a fast seller .. actually - if you are the right person i have another design which MAY also turn a profit ... anyway ... I"m in the cotswolds in the UK .. I"m good to travel .. and i want to make a move right away .. but I"m a chilled person so easy to work with.

    Herewith some more information that will assist you in a better understanding towards the app I have in mind:1.The app is of a business nature with very limited flash2.The core is a CRM system with added benefits aimed at specific users3.The CRM system will contain a timesheet factor initiated by the sales rep4.It will be android based and focused more towards tablets than phones5.The system must be able to handle data being added to it on a daily basis. 6.The customer record is broken into 3 different parts. Part 1 is basic data of the customer with feedback on visits. Part 2 is where the rep will capture a more detailed analysis of customers business. The system will then have to make rudimentary calculations. Part 3 is captured when a prospect is converted and again the data from 2 is used to assist in forecasting etc.7.Every record must be transferred to a master account, where reporting will be done.8.I have allowed for a number of drop down answers, to make live easier on the sales reps. These are pre-programmed9.A logbook will be derived by usage of this app10.The CRM system will be split into 2 portions with very similar layouts:a.Existing clientsb.Prospects11.The app must be available for offline capturing and will report, transfer data when wi-fi is availableI have developed Excel spreadsheets to get a better understanding of what needs to be captured, calculated, extracted. This is currently being tested in a real world environment by one of my clients at whom this product is aimed at.Attached DRCThis is a screen print of the timesheet as is. The rep will perform their planning for the next day When he actually visits a customer the start time will be activated and at the end of the visit the end time. I then use all the data derived from this timesheet to calculate a number of reportsCurrently this data is extracted and sent to the sales manager for inspectionAttached CRMI’m targeting the lubrication industry, as can be seen from this ‘discovery sheet’.Pg1 is the Prospect page for the CRM, but the existing customer will have a similar layout. In here we address certain questions, again with dropdowns where possible, that will help with the reportingPg. 2 is some calculations, while pg. 3 kicks in after prospect is converted. A hit rate is then calculated and certain products are advised. Here again dropdowns are availableNow you’ve seen some of my handiwork. All yellow cells are data cells that needs to be completed and everyone of them are used. I have deleted the unnecessary data which is nice to have and just kept the ones that can influence reporting and decision making. Orange cells are calculated cells.I unfortunately hid some of the fields at this point in time. On pg. 1 there is about 48 fields to be completed, Pg. 2 +-25 and pg. 3 +-25. Pg. 2 & 3 are dependent on certain factors and thus must be able to expand, similar when you add a line to a documentReportingThis is actually my forte as I love to examine data and compile useful reports to assist in decision makingI see the app as a living document, growing with the customer and expanding as new fields are added or drop downs become available. I thus need the app to have the ability to be upgraded with regular intervals.On the reporting side I will need a Master consolidated app. ThanksFranco Olivier
