Hello, I need a battery and system power management solution for a GPS tracking device that I am working on. I've been working on this for a long time, but couldn't find a proper solution. I used bq24072 - which was perfect for the job in theory. However I never achieved fast charging as it was in the theory. I tried with different circuits and batteries, the result was always insufficient. I also tried mcp73831, tp4056 and some other circuitries. As I told BQ24072 seems really perfect, but I couldn't figure out what the problem is. Anyway, you can bring a working system with bq24072 or you can provide desired functionality with anything else. As long is it works - it is ok. Characteristics: -The input voltage is 5V. -Battery should be Li-Ion or Li-po (which one you recommend for better performance and longer life) -Battery should be 3.7V and around 2000 mAh. -The system should switch to power source when external input power is on, when it is off battery should power the syste...

I need a circuit designed using TJA1054AT Transceiver and a MC with built in Can controller or separate CAN controller and MC. I would prefer MC to be PIC, Arduino, or AVR based. I would also like a C program created that would control this CAN bus running at common BUS rates but 83.3k must also be supported. I want to be able to add my own messages to the C code. I need this to be easy to understand and implement. As an example MSG1(ID, DLC, DATA bytes 0-7, Cyclic rate). Please respond with quote for this. I am looking at the end of March to start this project.

I need good BIM engineer to design a demonstration model of a multi-story building with different Intelligent building functions taking place on each floor. The whole building is networked back to one point and then to the cloud. For example the first floor may have intelligent lighting with Dali and KNX control, the 2nd floor may have electronic blind control on the windows, the 3rd floor may have all electrical circuits monitored for power consumption, the 4th floor may have BMS controls that are interfaced to our system ..... and so on. Full specification will be written but its essential that the engineer doing this has good graphics skills and understands electrical systems.

We we need a robotics contractor, to help us succeed in our project. If have a strong background in computer vision, robotic sensor fusion and in control, please respond. This is a hourly job because I'm not yet sure what is possible, so would like to start with a feasibility analysis and go from there. The general milestones I expect are: 1. Discuss possibilities. 2. Agree to milestones. 3. A feasibility analysis and unit cost assessment of each. 4. Circuit design for one or more of these. We need a roboticist who is passionate about coding and lives to solve technical challenges. You should be obsessed with keeping your code neatly documented, excited by improvements in performance/efficiency/reliability, comfortable with ambiguity, and driven to make things work. You'll be working with custom-built controller boards, so knowing your way around a circuit is a must and past experience in robotic control is a huge plus. While decades of work experience is not necessary, you should ...

Hello, My name is Robert, I am looking for individuals or companies to help design a custom highly affordable pid temperature controller that i can take the design to a supplier to manufacture for me. We are creating our own brand essential oil vaporizer but do not like the current chinese pid controller boxes on the market our goal is to have a custom one created so we can have our chinese factories manufacture. I am ignorant to this type of product but see all kinds of items on the market like Arduino or raspberry pi and i am very interested how cheap we can make this yet have the high quality parts and programming, We need this part to help build our own enail   [obscured]  /?gws_rd=ssl#q=enail Basically all this does is fit around the diameter of a circular titanium petri dish and heat it to a stabilized desirable temperature. (sort of like a retro fitted soldering station with a lcd screen to show temperature setting and actual temperature. With the finished product hoo...

Hey - I am a toronto based independent artist and need someone to help me design some PCBs for a project I am working on. I have sample designs but want to work with someone to improve on them. From what I understand, the project would be very straight forward and not difficult for anyone with any experience/education... but I have neither. I would like to work with someone from Toronto, but am open to anyone at this time.

Ok I have in mind a device that I have a vision for. The technology, potentially, could be used for many applications. I have one idea right now that would form the basis of design. **note this product involves electronic components such as market available GPS module / antenae. I am willing to pay to get a very good product, however it will be broken into sections, each with various weighting in progress payments. Meaning, no point paying the full amount only to find it isn't feasible. So I propose the following overall breakdown : 1. Investigate Phase - Investigate the components I propose or suggest alternates, with regards to achieving the specified outcome. Investigate any patents (freedom to operate), or potential for patenting this idea. Provide feedback as to whther the idea will work from a technical standpoint, and approximate costings of components, with basic design and manufacture approach. (In a nutshell, can my vision become reality with components currently availabl...
