Project objetive is to package an LCD display module, 2 LED's, on/off switch, 2xAA batteries, battery terminals, and wiring into the constraints of an existing plastic prototype housing with removeable battery cover and make them fully operational for field testing. PCB design and IC programing for LCD module already completed. Also, looking for guidance on how to improve and industrialize for production. Freelancer must be located in Michigan in order to complete this project.

I am not a technical person so bear with me on this description of work needed I own a company with a small fleet of trucks that deliver concrete. The drivers communicate with the dispatchers at HQ and each other via mobile radios I am interested in finding someone who can design a single channel recorder to capture the audio from the mobile radio in the trucks and record it into something like a Raspberry Pi computer with a touch screen on top of it that can allow my drivers to playback previous conversations to verify what was said, address locations, time of delivery, etc... The unit would have to be connected to the trucks DC power and be able to turn on and off with the truck without being damaged ( I am assuming some sort of BBU) Finally, there would have to be some kind of RF filter somewhere on the unit that could filter out noises that get created by the engine electronics. Also, the trucks are truck, meaning, they would probably get lots of vibration

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.

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
