My spouse works in the taskforce and revenue protection team of an electricity distribution company in Nigeria. The company is struggling with installation of pre-paid meters, which so far has proved inadequate. They have been reliant on boots on the ground and manual investigation and inspections, which has proved to be time consuming, inefficient and RISKY. I am interested in an inexpensive technology that can effectively monitor and report frauds, bypass, and electricity theft. And which can be scaled to prevent fraud, and protect revenue and prevent threats to life and of bodily harm to company staff

Dear Freelancer, I have a personal project involving IR signals which uses the CC3200 as the main processor () and Energia to program it. I want to be able to use something similar to the IR Remote library available on Arduino with the CC3200; mainly the sending and decoding functions through an IR emitter and receiver connected to the board. The IR Remote library for Arduino is based on the work of Ken Shirriff. This library can be found here: A detailed description of how it works can be found here: The IR sending part uses PWM while receiving uses interrupt. The CC3200 will be programmed using Energia (it is a free IDE much like the Arduino

My Adagio Entertainment S...Adagio Entertainment System unit stopped working, so I have replaced it with another similar unit. The replacement unit needs to be programmed to communicate with several existing audio zones within my home (just like the old unit was programmed). I have 10 zones with speakers in each zone. The Adagaio Entertainment System is connected to a Crestron Audio Expander unit, and to a Pioneer Elite receiver. All cabling connections would need to be checked, and verified to assure that each audio zone is working properly. One of my zones has 5.1 surround sound that would also need to be checked and potentially tweaked to assure it is working correctly. The surround sound zone also has a new wireless Bluetooth sub woofer that would need to be added to th...

...and bought the exp and credits to disassemble the M240 Bravo. A gun that i have a close personal connection to. So after i got a tiny little 3d printer for christmas (and i do mean tiny) i thought it would be cool to print a quarter or half scale model of it to put on my desk to assemble and disassemble while im on hold. It is a composite model of 197 parts and pieces ranging from large like the receiver to small like pins or springs and I'd like it to include all. If it saves money you can just provide the 197 rip files and i can assemble it in blender since i know the weapon so well. I would like to keep it fairly cheap if possible and of course i would provide my world of guns login so you can access the model. Thanks and please note it is NOT a paid model i just paid to ...

Hello, I need some software built that would runs on windows to work with my GMS (SIM 800C) The software needs to insert incoming sms to my sql table then I could display on a webpage.

I would like some code written for some Lora repeaters to send => receiver => action => repeat to the next Lora and then the next (basic on/off commands to control a digital output / relay) in a mesh type network. This will be used to extend the range of a 433mhz network indefinitely by adding additional Lora modules to the end of the chain (where the signal is weak) until the desired coverage/distance is reached. The code will need some acknowledgment so that the repeaters don't keep repeating the same command continuity and also the ability to receive the command from multiple repeaters (in case one fails). Materials: Transceiver's - Lora RFM98W / RFM96W (433MHZ) MCU - STM32L152; Nucleo-64 I have the parts assembled ready to test the code. I am using Arduino ...

The system will show the relevant transporter for that order. Upon selection transporter will get a notification for acceptance & decline as soon as the transporter accepts the order he will send one vehicle to the shipper's address. Upon the arrival of that vehicle, the security guy will check all the terms & conditions for that order. He...

The project consists in identifying a portion of the process depicted in below information and implementing a simulation of the roles and sub-roles, tasks and interactions taking place in the selected portion using either JADE or ...Jason. At least three roles should be implemented: student; professor-reviewer; professor-supervisor. For each role, at least five agents playing that role should be implemented. Finally, we expect that at least 8 different kinds of messages are exchanged among the roles (not 8 different messages, but "kinds of messages"; each "kind of message" will then be instantiated with the right sender, receiver, contents, when actual interactions will take place).The code should be carefully commented, and the report should clarify which part o...
