Hi, I need a circuit board designed and code written for a device that will transmit a weight over GSM to remote servers. The signal coming in will be that of a load cell. I would like the inputs from the load cells to be intrinsically isolated if possible as well. Once the signal is received by the Micro controller, it needs to be sent by GSM. That signal will be sent to a remote server and a web application will use the data to provide customer specific information. The unit will be able to take from 1-10 inputs from the load cells for now, depending on the application. Some Digital outputs from the controller will also be transmitted for alarms. The unit will need to be battery powered, with battery level indication also transmitted. I was thinking that readings from the load cell could be stored up and every couple of minutes sent to server to save on battery life. The project is in South Africa. So, I will need controller, modem etc. to be freely available here. I would prefer...

Dear Sir or Madam, I hope this is ok. I have squeezed in a much information as possible. My grammar is not good too lol. If figured the more details the more time saved on your part. Having to ask me questions. I work for an ice cream company and I am the delivery coordinator. My problem is the drivers are often spend too long at each delivery and the last deliveries get bad ice cream. I have come up with and electronic device that will allow me to track delivery times. My plan is to build a prototype times. Get it tested and then get approval to build 10 more. If it good well and head office like the device. Get it redesigned in a manufacture-able unit. So in your response please advise how much it will cost at each step. ? Design working prototype ? 10 Copies of working prototype to test ? Redesign to be manufacture-able I am paying for the design of the working prototype and first 10 copy for testing out of my own picket. So hoping to keep the costs down. But I und...

We are in need of an experienced EE who has worked extensively with low capacity strain gauges, specifically in developing the software to calibrate and filter the results. The project would entail: - Review of current PCB design and sensor - if changes are required, we understand - Coding and testing software to stabilize and interpret results from the sensor (firmware is in C) - Working with our current EE to implement that code into the existing base A successful project would involve us having consistent and accurate results from our sensors.

An analogue-digital converter 24BIT or higher is to be looked up and selected at Mouser or Digikey. It needs to have at least 5 channels and cover an analogue measuring zone of 0mv-5000mV. Further it should be run by an Atmexa32-16 or an ATXmega256A3BU. We have 2500mV or 5000mV as reference voltage available. We have 12V, 5V as general powersupply. For testing a demoboard should be made, which might be plugged via experimenting board or have a small self-made testing circuit board. A circuit diagram is to be drawn, in which supply voltages and REF-voltages are shown as input. Those don't have to be implemented on the board. External voltage sources do that for the test. A sample code (fully functional for 5-8 channels in multiplex) has to be written in C in the Atmelstudio 6.2. Existing sources in the internet can be taken in case you will not cause any problems with copyrights. The measured analogue values need to be made visible via an external software (RS232) e.g.   [obscured]

The goal of this job is to develop a schematic for a buildable prototype of a product with 2 Mobile LCD (3" diag) units, run by a mobile processing unit. The screens will display identical, high resolution static images. The processing unit, when connected via USB to a computer, is controlled by a user installed program, generating a GUI which allows the user to upload images to processor memory, to be displayed on the LCD modules. (I have specc'd out the software and will be writing the code / developing software) Stuff like shape and positioning of a battery(s), USB connector and cable, as well as casing requirements, I consider part of the design process. Part of the development process needs to include the design of a control board, for interim testing. Specific aspects of the project are under NDA, (i.e nature of visuals to be displayed, product target market) and would be provided upon selection of a bid, along with anything else relevant.
