We require a person to integrate three images from three sources,: 1. Infra-red using the ATOM 640 camera block. 2. Image intensification using Photonics X5 16mm tube. 2. The ODG R7 camera on the AR Glasses. The "fused" image needs to be displayed on t screens, left and right eye.. Hardware and software to be selected by contractor.

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.

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.

i am looking of some onto convert some arduino code to c++ with chinos/rt based OS from arduino code, i also need you to do the opposite. adruino uses atmega chip the chinos/rt uses stm32f100 and the last thing is i need to do help add support for a device to one of the codes. the hardware is a wii nunchuck replacement pcbs made specifically for controlling an electric speed controller.it has been made because current wireless wii nunchucks are unstable and have bad wireless connectivity. the wiiceiver is a pcbs that was deigned to plug in a wireless nunchuck receiver in and output pwm signal for and electric speed controller and servo. i need to make the wiiceiver read the axis and button presses from my nunchuck pcb. but i want my nunchuck pcbs to stay comparable with arduino so i was going to allow support for stm32f103 and them release arduino code to the public. ardunio code: https://github.com/jaustindavid/wiiceiver chibios/rt code: https://github.com/vedderb/nunchuk_mod

link to kicad project. https://drive.google.com/file/d/0Bym9XrdeViekWDZTSjZTRG1iTmM/view?usp=sharing hello , i have a project for you. this is an electric speed controller. this design is finished but i want to do 2 things to it. i want you to study it and design a way to join 2 together. i want you to join the positive and negative power inputs into the 1 and have them closer to the bottom of the pcbs. i want you to consolidate the parts so they share any parts that can be shared such as the voltage regulators usb and if possible the mcu. the second thing that i want you but is actually the priority, is do is make a second pcb using this current single pcb design and reduce it as much as possible. the current speed controller is made for 60v and rated for 100A i want to make one that is small and only rated to 10A at maybe 24v. the motor control ic that is currently used is the TI DRV8302 i want to replace that chip with the DVR8332 that has lower power ratings but also has...
