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)

my project consists of 2 parts. 1.)the calculation and sizes of the laminations(noss v470) as well as the windings for 3 phase 220v 4 core 20kva alternator. 2.)i need a circuit designed for the alternator that automatically add an adjustable load the main load. the circuit must rectify the alternator winding and combine the to form a 240v single phase output. the out must the be inverted to 50 Hz .whether the phases must be combined before or after the frequency conversation i don't know.after this the 240v 50Hz goes to the load. from the load it must the come back to an artificial load. the size of the artificial load will change according to the output. the artificial load will always be the generated power being produced by the alternator at that time minus the main load at that time plus half of the resultant . for example if the generator is producing 6kw and the load is 2.2 the the resultant is 3.8kw. the artificial load must now be 3.8kw multiplied by 1.5. this only applies...

I want develop wireless digital signal sender and receiver (RF transmitter/receiver) circuit to be developed. The device must be operated with 5V current (taken from USB) and input 5V USB signal to the wired signal sender. The receiver must be operated with 5V current (separate current source) and must receive 5V wireless signal and switch-on a 5V light bulb. When I feel confident on your skills I will give specification. And this involves electronics and software engineer (embedded system development). This is a small project which will be expended later. For now keep the budget as fixed $800. Be open and you can ask any questions if you want to continue truely.
