I am looking for an experienced and knowledgeable engineer to aid in the design and prototyping of an embedded system for a product we are planning on bringing to market. The design and components should closely mirror that of the Raspberry Pi Model A+, with some components removed and some added. In particular, we desire a pre-certified (FCC) wireless-n module and 4-8gb of eMMC or NAND flash. HDMI and two USB will also be required. A successful candidate will have the ability to provide a schematic of the design, will be able to aid in the component selection, will be able to produce a functional prototype and provide required support for internal embedded linux development. Milestones for the project are anticipated to be, (1) component selection in coordination with the client, (2) delivery of approved schematic and (3) delivery of functional prototype. Ongoing opportunities for a successful candidate may be available. Please fell free to contact us with any questions relating ...

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...

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.

Hi, I'm looking to have a two input one output HDMI switch built that upon someone ringing a doorbell, it switches the input in a HDMI switch to the CCTV input from the cable box input for 10 seconds. Ideally it would have a button, or ideally a remote to switch to CCTV for 30 seconds then have it revert automatically back to the cable box input. The idea is that when someone rings the doorbell the office TVs all switch to CCTV for a brief time then go back to cable. Thanks!

We are working on a project which involves some electronics engineer's expertise. The details of the project are confidential and cannot be disclosed. We need an electronics expert to build a circuit which follows the logic as stated below: 1. Start the process 2. Linear actuator move to position (using position sensor) 3. In that start position, the temperature sensor (which mounted on the linear actuator) starts taking readings. I would like a sensor which can take about 5-10 readings a second. 4. Solenoid open 5. Linear Actuator moving again to a given position in a given speed (speed control is important ? low speed) 6. Stepper Motor move to a given position (very low RPM, low number of steps. ) 7. Temperature sensor detect needed temp ( adjustable, probably need the use of PID CONTROLER) 8. Solenoid shut off 9. Stepper motor move back to original 10. Linear actuator move to original position. 11. End of program. NOTE: This process has to be repeatable and flexible for adjustments ...
