Problem with Tesla's Battery. Tesla's electric cars only go 250 miles before it needs to be recharged, Our product will double that or 500 miles before recharging. This device can be used in Spaceships, drones, Iphones, The applications are endless. We want to find an electrical engineer that will sign a non-compete clause and verify our findings. We are located in Maui.

I require a PCB compliance test. test will determine if PCB is capable of passing EMC/EMI compliance tests and all relevant tests relating to CE mark and FCC standards. 1: 2 x PCBs need to be tested. 1 is extremely simple with just 6 switches on it. the other is more complex. 2: Timeframe would be as soon as possible. these boards are fairly simple so shouldn't be too difficult.

I have a simple circuit that is a battery operated rgb color switcher that runs on a PIC10F202; When the button is pressed, the single RGB LED changes to the next color in the sequence. When the battery is installed, the unit is on, and when the battery is removed the unit is off. What I need is to have the code modified so that the uController behaves in the following manner: 1 Unit is off with battery installed 2 Button is pressed once 3 Unit turns on with last selected color illuminated 4 Successive button presses will cycle to the next color in the sequence (R->G->B->Y-C->M for example) 5 Unit will stay illuminated in the current selected color until, 6 Long press (2 seconds) will shut the unit off and save the last selected color in memory 7 Operation repeats as above ...

PCB design, manufacture and firmware programming for a heating controller. It will involve multiple inputs and outputs, both digital and analogue, NTC,0-10v, pulse, CT, on-off, power supply, separate high quality touch screen controller, 8 gig SD storage, Modbus master, Lora, Zigbee (connection to Sonoff sensors), Wi-Fi and LAN. It must connect to a website for analysis of data and the ability to upload data and download instructions and update the firmware through the internet. The project will also include the development of the firmware, website apps ect. I do have a precious version written in C as an example. A full description of the firmware will be supplied after a NDA is signed.

I need a circuit diagram consisting all the necessary transistors and logic gates , to provide power to a gps, a bluetooth, a small speaker , all powered by a small rechargeable battery. I need this circuit to be less power consuming and provide more efficiency

I need experts to have good experience in power line communication to build firefighter telephone system by using addressable node

This is the glymse of the project: This project uses multi-frequency and multi-constellation Global Navigation Satellite System (GNSS) receivers to receive and converting from the received International Atomic Time (TAI) to Coordinated Universal Time (UTC). Once received it syncs the onboard Temperature Compensated Crystal Oscillator (TCXO) or Oven-Controlled Crystal Oscillator (OCXO). Design Schematics, PCB and Firmware Development. Details of the Project will be discussed after evaluvation

The project is to read frequency from a magnetic sensor and display the reading on a stepper motor and oled display and design the PCB board.

Hi, We have designed a PCB around the STM32F401 + SIM868E. This PCB has been designed in Altium and has some connection issues which needs to be resolved. So in short the PCB design needs to be validated and potentially reworked. Please contact for more information.

Hello everybody, me and my six person team are developing a real-life hardware payment portal which runs with crypto currency payment like IOTA, BTC and ETH. The payment portal has a display introducing the customer. After successfull payment the integrated switch turns on any service, e.g. washing machine (pay for action), car wash (pay for action), car charging device (pay for energy). There are endless use cases. See benefits in the appendix. For this job I would like to get a print ready DIN A4 brochure 2 or 3 folded, both sides illustrated. The hand-over data should be TIF, PDF and native format. After this first project, if both sides of partnership are confident with each other, I would like to continue with designing a proper logo, website and possibly a smartphone application...

Hi, We need help from electronics hardware and firmware designers who have worked on DSPs before because device on which we are working is based on signal processing. Further details will be shared with selected freelancers only. Thanks.

I want basic and pcb design which can be used for all devices. containing essential components like microcontroller oscillator power module etc.

We are working on a somewhat stealth electric car charging company and need assistance from a EE experienced in PCB design, high voltage, high amperage, and more.

You must have EXTENSIVE experience with hardware design using ESP32, as well as EXTENSIVE experience and successful background with firmware for ESP32 products and related WIFI & BT work. This project is for a battery operated device with very low QC current. It includes writing firmware for codec and cost effective board design to allow basic half duplex voice through wifi to the device. The device is battery operated and must be designed with extremely low QC to allow years of deep sleep. Candidate must have extensive experience in assembling sample SMT boards [in-house] including the small smt components. You must successfully create samples quickly in-house. It is imperative to have tools such as spectrum analyzer, scope and extensive knowledge and experience with refining the ...

I have 2 PLC,s communicating with wireless Modbus RS 485. Slave requires minimal code measuring up to 30 PPS, battery voltage a latching relay and possible count reset command. My intention is to eliminate the Slave PLC. I'm looking for someone who can help me with: (1) I have programs written into 2 PLC,s 1 Master and 1 Slave they are linked via RS 485. (2) They communicate through 2 RS485 wireless transceiver,s The Slave PLC has got a very simple program in it . My task is to move the program in the Slave PLC into a microcontroller. I'm presently using an Arduino UNO for the task I've got the majority of the coding done. In closing, I need someone who has SPECIFIC knowledge in IDEC PLC,s and Arduino microcontrollers.

Need to design a vending machine. Outer body: 6m Shipping container Selling 12.5kg maize meal packet in bags Full layout, Electronics, Solar Power, 3G mobile communication, voice + camara’s. Visa/Master card system.

The DC-DC module(NCS3S4805SC ) is not working now. I am looking for EE engineer. I attached schematic. He will become a member of PPD Development Team.

We would need to create a hardware to sit on a raspberry pi or an arduino and connect to vending machines control boards. We would like to read data from the vending machine through the MDB protocol and send instructions to the vending machine. Above is the requirements. Please don't bid on this project unless you got previous experience with mdb protocol.
