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 ...

I am developing a product and need a discussion with an EE to discuss an MP3 type device. Depending on the discussion I may need an EE to develop the 3D drawing of circuitry and help develop the prototype and cost out production. I would think the initial call would be an less than an hour, but I will pay an hourly fee. Great way to make a quick buck and get a good review.

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...

I am building a robotic lawn mower. Like many other robotic lawn mowers, this will likely use a perimeter wire to detect the edge of the lawn, but I am also interested in other approaches that could work here. 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 for each approach are: 1. Discuss possibilities. 2. Agree to milestones. 3. A short summary of the trade-offs available. I'm mostly interested in the feasibility of the approach, the cost per unit, the power used, and how accurately we would be able to detect the edge of our cutting area. (1-2 pages.) 4. Agree to trade-offs. 5. A deep cost analysis of how much this would cost per unit and to develop. (1 page.) 6. A circuit design for this approach. 7. Any support (such as firmware) needed. 8. A PCB layout for this design. The system currently is using 6V batteries, and 5 volts for the electronics and is based...
