# 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!

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

ZeeVee manufactures translation devices for video. These are small devices (about 4"x7"x1") that usually reside near television or near a video source. In many cases users want to rack the devices up densely in a 19" rack. I need a rack cage, and brackets designed to hold the individual devices in that cage. There are probably 2 or 3 pieces to design. Sheet metal is the medium. There are no unknowns as ZeeVee has models for all the devices to be mounted. Freelancer should have all tools required to generate a model and submission package for a sheet metal manufacturing house. ZeeVee will handle submission and interface to fabricator.

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.
