Dear friends, Desigining and simulation (in matlab simulink) of solar power pumping system including PV panels, DC to DC converter, motor selection/ desiginig, MPTT controller etc. Our water requirement is 1740 gal/day, Pv panels should be designed for Somalia (Afgoa town: Latitude 2.0333° N and Longitude 45.3500°E). Type of motor is BLDC (Brushless DC Motor) or Induction motor 1. Complete report about the Designing and calculation of parameters of PV Panels, size of panels with calculation MPPT Controller, DC-DC Convertor, BLDC Motor. 2. Complete description about the behavior of graphs e. g. (i) At the output of PV Panels (ii) At the output of MPPT (iii) At the output of DC-DC Convertor (iv) BLDC Motor outputs like current, speed, voltage, power etc etc Best regards, Hashim Abdullahi Abdi

I require a custom electronic product to be made. It is just a bluetooth receiver for iOS and Android, that allows to play / pause a music. Thats it. This remote must have a LED and a ON/OFF switch. Also it must have a cable to a small button (image attached as an example). We will require 500 units of this product. Instead of a remote thermal sleeve can be used to save on production costs. Price bellow is for development and 500 units of the finished product.

Car dashcams are increasingly popular and most also come with a parking mode. However there are issues related to car battery discharge. There are solutions such as Celllink B, Blackvue Power Magic etc but they all have their disadvantages and issues. Goal is to design a battery pack that 1. Easily installable and with high capacity 2. Programmable with delayed start/stop etc 3. Add remote access

Hi, We are looking for writers who are from a technical background, but has the acumen to write interactive and appropriate content for students between the age of 9 to 15 years. You need to have the technical know-how of all basic electronic components and circuitry, and you need to know how to explain such concepts to a kid. Other than that, this is an instructional book on how to build your own wireless remote operated vehicle, so familiarity with RF communication, Motor Drivers, Encoder & Decoder IC's and breadboard prototyping is a must. The main content needs to be child-friendly, so your command over the English language needs to impeccable. We will be selecting you based not just on your technical knowledge but also on how well a content writer you are. One last thing : Plagiarism will not be tolerated at all. Looking forward to your applications. Regards, Ushan Dhar

Design three types of universal LED bulb driver: 1.) Using minimal component to keep cost down (See "01.jpg" and "02.jpg" attachment ) 2.) Using integrated circuits for higher brighter/Life of LEDs(But cost must be low) 3.) Using some high end technology to keep Quality and life longer(You can also add extra features like light sensing technology and make it energy efficient) Input: 90-260v AC Output: Volts: Universal Amps: Configurable just by replacing transistors or any single component(No need to change design) Note: I do not want any current leakage/wastage (or as minimal as possible)
