Design power controller for 1 to 10 hp 3 phase 480 volt induction motors. Similar in concept to VFD, however we are not looking to vary speed but vary power to motor while maintaining speed.

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 ...

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...

Hello, I am a mechanical engineer with several inventions. One I would like to develop comprises of electronics. Although I do have limited knowledge in this field I would rather pay someone who knows what they are doing. I would like a PCB designed and converted into Gerber files ready for prototyping. I have a list of requirements for this project but briefly outlining the PCB requirements: *miniature design *low power usage design *energy harvesting to convert movement into electricity to charge the battery *Wi-Fi to transmit data to apple/android *gyro meter to detect movement *temperature sensor *microcontroller I would also like embedded software to run the PCB once prototyped. If interested please contact me and I can provide a lot more detail and outcome desired. Cheers!

I require assistance in designing a pcb for an induction heating circuit. The design is based on a royer oscillator and includes an atmega328, a bluetooth module, and several IC's for reading input and output. The design is not too complex but is beyond my capabilities in regards to pcb layout. I currently have an eagle schematic on hand.

I'm looking to design a prototype with electrical components These electrical components will be used for products that sell between 10$ - 70$ to consumers. So these are not big products. They are the size of regular home appliances. Some of these devices require electronics and some do not. Some are purely mechanical, or may not require electronics in the first place. I'm looking for somebody that can design a digital schematic of how everything connects, if at all possible. If digital schematic is impossible then a physical prototype will need to be made, however a digital copy would be preferred. I will reveal more once we converse a bit Looking forward to hearing from you gentlemen!

A Non Linear Resonator model has to be designed in following Steps: Step 1: Designing of existing model into Advanced Design System (ADS). Here I will send you all the details you just needed to have good skills of ADS software and then you can able to design it easily. I just needed the existing results to verify in ADS . (Will pay 20% amount) Step 2: After designing the Non linear model successfully in ADS. We can go ahead and design it using Verilog-A. Knowing the circuit designs in ADS will help plus I will also provide you the 60% codes and you just need to put all the work together and verify the results with ADS software results. (Will pay 50% amount) Step 3: Documentation with No plagiarism .(will pay rest 30% amount)

I need an electrical engineer to help me design a PCB for a strain gauge indicator. I have most of the schematic already, but will also need some help connecting the already-designed circuit to the PIC18F, so some research may be in order if you don't know how to use the PIC18F. Attached is the schematic. Hope to hear from people soon and hope to get this done as soon as possible! :) Note: I will handle all the manufacturing myself.
