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

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.
