need solar pv design for solar farm project 1.5-3 MW Please also include Require system impact study and facility study 1. Transmission line system on the procured land 2. Generation expansion 3. Transmission expansion 4. Load demand consumption/load forecast/load flow (Peak and Non Peak) 5. Proposed connection 6. Grid stability This project is to do solar farm in California, USA It will use to estimate the cost of the system, so if you already done similar kind of project before, we can use your duplicate plan that you already has one.

Hi, We need a drone / UAV specialist to design and build a custom drone prototype for us. We require the complete electronic & communications design, basic drone design, integration and build of the prototype drone model along with the controller. Drone's Basic Requirements: - Need to have a minimum drone & controller undisturbed live communication range of 12 KM - Need to be able to carry a minimum payload of 1.5 KGs (Roughly 3.3 lbs) - Should have a battery life for non-stop use of 45 minutes. - Should have a minimum flying speed of 45 Km/h - GPS Pinpoint Following - Drone should be equipped with a Camera - Controller should be able to view through the drone camera These are the basic specifications of our requirement. We would love to discuss more if you are interested in working with us on this promising project. Further opportunities are also available with us in terms of partnerships. Looking forward to hear your ideas.

As a first step in creating Electrochemical etching machine we need a proof-of-concept experimental platform. It should : 1)Provide pulses from 10us up to 10ms of DC current to load (U=15-40V, I=100A max) 2)Have all adjustments to change pulse time, pulse voltage 3)Have outputs for oscilloscope to detect real current and voltage forms For the very beginning of the work, a circuit with rectifier, a mosfet, mosfet-driver, pulse time adjustment and inductive load overvoltage protection will be enough, so we can test your skills and get early concept. The load is a gap between electrodes, filled with electrolyte (NaNO3 water solution), and has complex resistance (active, inductive, electrochemical + inductance of power wires) If the proof-of-concept shows that the idea is right, we can offer long-term work for creating full power, complete etching machine

We are paying for written application notes based on our configurable mixed signal ICs & integrated power switches. These parts are very versatile so there are many applications that they can be designed for. The application note should be a 1000-3500 word technical white paper describing an application and how it uses the SIlego part. Writer will be responsible for generating the content as well as writing the app note. · 1k-1.5k word manuscript + 2 figures: $750 · 2k-3.5k word manuscript + 3 figures: $1,500 We have many topics that we can suggest for this or you can suggest your own for approval. Here are some examples of app notes that were done in the past: http://www.silego.com/softdoc/app_notes.html Please contact us if this is something you would be interested in doing.

We are looking to develop a sensor that would help people practice their service toss in tennis. We are thinking there would be a sensor you could place on the ground and turn on and a sensor you would wear on the wrist of the tossing arm. When the ball goes outside of the set boundaries the sensor would alarm. We need a for the user to set parameters of the sensor boundaries based on their height.
