We are looking for someone to design a simple satellite receiver circuit. This would be used for obtaining audio only from FTA satellite transmissions. The output from the LNB would connect to this circuit and the output from the circuit would be a two channel analog audio signal for passing to an amplifier. The circuit would hence include satellite tuner, qpsk demodulator, and mpeg-ts decoder. Selection of the desired frequency would be via microprocessor. The deliverables would be: - A schematic of the circuit. - C++ program for controlling the circuit for the specified microprocessor.

# Summary We are looking for the design of a small-sized battery management system for Lithium Polymer batteries. # Description The batteries are integrated into several systems used in agricultural and semi-industrial environments which means that customers expect the equipment to be very easy to use. Currently, batteries intended for remotely controlled vehicles are used which has the advantage of having a high power to weight ratio but the downside of being cumbersome to use. # Requirements Thus, in the final design of this job we are looking for the following: * Automatic balancing of a 6S LiPo battery pack while charging * Status reporting on: * Current state of charge (Fuel Gauge) * Current flow * Voltages of individual cells * Number of charges / discharges * Health Monitoring These functions should be integrated into a small & lightweight PCB that can be added to a pre-existing LiPo battery pack.

Hi, I need someone who is an expert with solar panels and has a fantastic understanding of all of the solar panels that are on the market. I am looking to put solar panels onto a small vehicle tracker. I am expecting that these devices will receive 1-2 hours of daylight per day and 3 hours of low/ artificial light per day. I am trying to minimize the $/watt of the panels. One important limitation is that all of these panels must fit onto a 13 square inch surface area or about the size of an iphone 6. Thanks!

Hello, I currently have a lot high powered computer equipment in my house and would like to in crease the amount of servers I can hook up, but requires more power. I I'm a 3 townhome condo and was told that tandem breakers would help me pull more power, as well as potentially install additional circuits in empty slots as well. I have posted pictures but please feel free to ask me any questions if you have any. I am also in Vinings. Thanks.

Programming firmware for Atmel SAM D21 microcontroller. Following functions have to be covered: - basic firmware for SAM D21 clock, ports, etc. - DMX receiver compliant to DMX512 protocol. - 2x16 character LC display vie SPI - 4 buttons for control the menu at LCD - The DMX start address can be configured via buttons / LCD - 8 PWM outputs, with 8 respective 16 bit. The TCC unit of D21 have to be used. The circuit is developing right now by ourselves. The challenge will be to start the programming without final board because this project is under time pleasure. It may be ture that the firmware have to be programmed without the final PCB!

AIM - To make circuit using sonar(distance sensor) as input which will be deployed in fast moving vehicle and to take output in form of vibration and display Objective - Sensors should be sensitive with range of .1m to 3 m. Need to know the options with respect to quality and cost Circuit should be designed with input from sonar and output as vibration(closer object gets, more vibrant it should become), and color changing LED (changing color from red to yellow to green) The power to be supported by solar films as well from external battery. The communication should be wireless for LED display as well for vibration module if possible Kindly let me know if more details are required. Thanks and Best Regards

I'm looking for a programmer to help me write code for an arduino run circuit. When a button is pushed, two things happen; 1. one led lights, then dimm's down within a 1/4 of a second. 2. the next led lights, then dimm's down within a 1/4 of a second. I will be using super bright led's, like the ones shown here;   [obscured]  /products/531 ill be looking to make this gimmick pretty small, but enough current to supply the led's. To further understand my requirements I would be happy to discuss through Skype or google hangout. This job is also a trial employment; as further electronic products will be needed in the future. If there's any more information you require please don't hesitate to ask.

Two boards. I require a board to interface to HopeRF RFM95W. The antenna needs to be small chip antenna. The board needs to be compact. The second board requires is based loosely on the Mediatek Linkit Assist 2502. The board design requires only the processor and the GPS. Both jobs should be easy for someone that has RF experience and board design. Both boards need to be tested to proof that it is working. Both boards need to be designed in Altium.

General This project has the ability to send GPS data to a central server using GSM over TCP/IP. There will be some input to control and output for activate ex. a relay. As MCU platform the ATMEL 328p has been used running 8MHz. It is essential the program use absolute minimum power consumption. Programmer need to know how to set MCU, GPS and GSM in sleep and standby mode. The hardware contains a 3 axes sensor for Tilt, acceleration and movement, which will be part of the software. The hardware is driven by a 400mA 3v7 battery. All documentation will be available with direct technical support from hardware supplier.

Research firm possess a design for a voltage controlled mosfet switch. We seek an experienced subcontractor to receive our build package (schematic, parts list and component connection paths) to produce a professional quality PCB complete with the working and tested circuit for delivery to us. Job includes: a) produce a PCB layout based on a circuit schematic provided by Research firm. The circuit has less than 25 components - all components are through hole style. See attached schematic, minus part numbers. b) Order parts to populate the PCB based on parts list provided by Research firm. c) Assemble, solder and test the populated PCB to assure proper on/off function. This voltage controlled mosfet switch turns on at 550vdc and off at 220vdc. Applicants responding to this job offer must have a power supply capable of operating at these voltages in order to test functionality of the circuit. If this 1st job experience goes well, there are other opportunities which may be discussed....

You need to design a 2KW PM reluctance motor. I will send the full specifications as we proceed. I prefer you use JMAG for the design. Ansoft Maxwell is ok though. After the design is approved you need to source the material and assemble that stator and the rotor of the motor. The bearing and the balancing are not important. I can manage that at my side. I will provide more motor specifications as we proceed. Regards
