Background: As you likely already know, to control amount of power a flash puts out, flash duration (and hence light output) is reduced by a thyistor control that quenches the full power flash early for light output less then 100%. Requirement: Need a circuit to be designed (along with PCB design) which will register the flash quench duration (generated by the center pin on a DSLR flash connector) and converts it into a power output that can drive a bank of high speed LEDs. Either using purely discrete components or using an arduino (your choice whatever you think is simplest). If a micro-controller is used, I will need the code as well. The output of the circuit should be able to drive and control intensity (either PWM or otherwise depending on the LED driver driver used) of a bank of LEDs.

I need someone to program an Arduino touch sensor pad. The main electronic components will be an Arduino MCU, touch sensors and LED lights. I have a few options on how I can make it, but I have a limited background in electronics so I need help first to determine which method would be the most effective, especially which type of sensors would work best for the field conditions. Once we decide on the physical layout, I need you to program the Arduino to pick up the sensor signals to light up the LEDs.

I am looking for project manager/lighting auditor/electrical engineer to perform substitutions for lighting audits that I my team physically performs here in the US. Your tasks will include performing the substitution inside our program, one click Cost Benefit Analysis report generation, submission of rebate applications to various utilities, obtaining bids from electricians & tracking of stages of entire project. Please review the training videos and website for the program I use. www.ecoinsight.com You will have to substitute existing lighting for LED Lighting in our catalog at my written direction. (notes that I leave in the line items and program). I am searching for someone who has done lighting energy audits before, and/or has experience managing electrical installations, and/or has used the ecoinsight product before. If you feel your qualified for this position we look forward to hearing from you... Training on use of program provided by company.

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...
