Need a schematic and BOM for the wiring and components for a locator system device. The heart of the system will be a microcontroller similar to an Arduino Mega connected to a NFC Reader Shield, GSM Shield, having GPS, Wi-Fi and Bluetooth connectivity. The system will include a Lithium polymer battery, charging circuit using a mini USB port to plug in an AC charger. All components are to be generic off-the-shelf to keep cost down. It is preferable to use existing Circuit designs as much as possible to shorten the debugging process. Freelancer must be able to take care of the system design, including electronic and firmware. Electronic design includes schematics, BOM and PCB layout. Firmware design includes the implementation of all the logic functions and demo A general component layout, and functions and features requirements, will be provided as a guide. Freelancer must sign an NDA and be able to complete the job in 4 days, and be immediately available for any revisions requi...

We need an experienced expert in electronics/automation that will help us design an electronic schema or automation set-up that will allow us to cover the following scenario: - we need to acquire data from a set of analogue sensors - 128 per module, with the possibility to connect multiple modules up to 10 (if it is possible to be more, the better), all being the same type of sensor (e.g. temperature, pressure, load, etc) and to transmit this information over a GPRS modem to remote server; - there should be a PLC or another electronic schema that will ensure that all sensors installed are read, and we do not need to have their values in the same time, so we might allocate say 10 minutes to read them all, one at a time - the data that the PLC will send through the modem should be similar to this pattern: ModuleID.SensorID,ValueofSensor; ModuleID.SensorID,ValueofSensor; etc we need the PLC to translate the analogue values into their actual value (e.g. temperature, pressure, weight, etc),...

I am looking for a talented electronic engineer to help design the smallest PCB possible with the following specifications. (More detail later) I have an Arduino Mini-Pro hard wired to a GSM Module that I would like re-designed and shrunken into a single PCB with a standalone Atmel MCU and GSM Module. I have already written the software (in the Arduino IDE) - which would need to be improved for performance and re-written in C/C++. The software is quite simple. The following are required: BOM GERBER SOFTWARE Looking forward to working with you.

We are looking for someone who can design and built a prototype circuit board with a battery and can provide us with information on how to obtain the parts. At the moment we are in the prototyping stage for a product that is under development and need to get a prototype circuit board built. Keep in mind the device is small, about 3 in x 5.2 in x 1in and is going to contain numerous ports, like USB, SD Card Reader, HDMI, etc. The device will also contain a large rechargeable battery that can charge multiple devices connected through the ports. Feel free to contact me if more info is needed.

I have manual for medical software to be proofread. Text has 4600 words. The sample text: The previously mentioned main tasks of the program are: ? Sampling sensors ? basic task responsible for collecting data frames (Data Frame), which are coming from all working sensors, and saving them to the SD card in form of data blocks (Data Block) ? Communication via HTT ? this task is sending and retrieving data from server via GSM modem; the pending data on SD card are collected into larger packets (Data Set) and sent through HTTP; on the other hand the server listens for packets received and sends the data to update time and installed in the device firmware ? User interface ? this task allows operator to run a graphical user interface (GUI) and communicate through it ? Communicating with I2C (Inter-Integrated Circuit) bus ? another basic task, it is used to communicate peripherals (e.g. sensors) with the internal resources of the microcontroller Some computer terms: Description contains...
