We are looking for an engineer to support our team in the development and testing of our IoT devices. This requires a variety of skills and a good understanding of microcontroller hardware, embedded C programming, and mobile RF solutions for IoT devices (NB-IoT and CAT-M1). We work with optical sensors, so experience with embedded computer vision is a plus, as well as machine learning implementation on embedded systems. The work will consist of assisting in the development and testing of firmware developed in C, testing device functionality and identifying issues, recommending solutions and improvements based on test results, and communicating these to the firmware developers. Work includes understanding and testing: - Device microcontroller hardware and peripherals. - Firmware and device...
The batteries are 2S using 18650 or 21700 the cells we are currently using are Sony VTC6 3000mAh/20A and Molicel P42A 4200mAh/30A. Larger capacity cells will be investigated and used as they come available. They are housed in a nylon case and are wired in series having a centre connection for charging, there is no protection circuits in the batteries. They plug into our drones and controllers and will be plugged into the charger as required. The chargers are to accept either two or six battery packs and are to work with any number plugged in. We expect to be able to plug in up to six 2S battery packs which could be all at different charge levels and each will be balanced and fully charged on completion. An led showing fully charged will light on each pack when this is accomplished When ...
I have a project done with Altium. The board is working but it needs some changes, I already made the changes in the schematic. I just need the layout to be updated and verified. There are about 20 netlist changes, none of them require the movement of parts of creating new ones. I need the updated PCB layout file and Gerbers for production. Thanks
We're based out of Chennai, India. We're shooting a short film and one of the elements of the film shows a thief looting the riches. We're in process of designing a bike which the thief character uses. Based on our script the bike will have a rotational license plate (as shown in this youtube link: ). The rotational number plate needs to be operated through RF remote as well as in-bike buttons (mandatory). It should be 100% functional as shown in the video. I already have some expertise around IOT and 3D printing but I don't have time for this now in the middle of the shoot so I would like to hire a professional who can completely do it for us and courier the equipment. It needs to be as sturdy and top quality as it is going to be fitted on an offroad bike. We are aware...

I basically need a programming tool. I'm a tuner and i need to modify parameters of certian ECU type To do this i need a way to read data from MCU and write it back once i modify it This is engine control module for a car (Ford) manifactured by Siemens (SID212EVO) with Infineon Tricore TC298 processor , We need a way a read and write data from/to this processor , we have over 100 units awaiting modification so price is not a problem, none of current leading market ecu writing tools (magicmotorsport,alientech,autotuner) currently supports this kind of ECU , this particular MCU TC298 is also on other ECU's by different manufacturer (Bosch,Delphi) and alot of tools support it but apparently this siemens ecu is not yet supported by any tool yet . Probably enchanced security...

Hello, I have a arduino mega project with LCD, initially which was started with arduino uno and rotary encoder to feed commands. But now we want to upgrade it to arduino mega and LCD. We already have a code for the same and want to debug and add all the required codes and make a perfectly working model as per our needs. One should be very thorough with arduino mega and GUI design on LCD for the project.
GC Front Panel drawing using FreeCad and training on use the FreeCad to modify the existing Front panel draw. 1. I have the XL table with measurements parameters for parts and the parts position. 2. The Front panel will need to be expended to fit new Nextion 7" display with basal. 3. Final Front panel Draft size will be decided when drawing is operated by me.
I need someone to build hardware prototype GPS device using module NRF9160 SIP (Nordic Semiconductor). It needs to send data to server using internet from SIM card, also battery level and accelometer data from sensor. For more information please contact me.
Hello, As the title says, I would like to add some sort of antenna to the HM-10 BLE 4.2 module in order to increase it's range, so the bluetooth is discoverable at bigger distances. Looking to increase the range by 5-10 meters only, nothing big. I need someone that understands antenna design and has experience improving the range of bluetooth modules. Thank you! Marius
I need a code for arduino and the language is c++ for this project: Our project is an automated pillbox: It has arduino uno wifi, LCD I2C, keypad 4*4, buzzer (alarm), 2 IR sensors, 2 micro servo motors. 1- the patient will set the pillbox he will enter date/time. 2- he will choose number of medications (1 or 2). 3- he will enter the time and number of pills for each medication. 4- when it’s time to take medication 1 alarm will go on until the patient press the button on the keypad. 5- the door of medication 1 will open using micro servo motor. 6- there is IR sensor inside the compartment of medication 1 to sense the medication has moved or not. 7- the patient has to conform taking the medication if yes number of pills for medication 1 will reduce by 1 and upload to the cloud...

Note: I'm looking for developers that have previous experience with GreenPak ICs I have a sensor that consumes ~300uA at 3.3v and I need to reduce it's power consumption by duty cycling it. The GreenPak design will need to power up the sensor, read the differential analog output, store the number of changes in a counter then power down the IC. The counter will be available via I2C for an external CPU.

The solar cable design system should take into consideration the following factors: For each of the different solar panel string cable configurations (6, 8, 12, 16, 20, 24, 28, and 32), the following design requirements should be taken into consideration: 1. Voltage and current rating of the solar panels: This information is crucial for determining the size of the cables that are needed for each configuration. 2. Cable insulation: Choose a suitable insulation material that can withstand high temperatures and UV radiation. 3. Cable length: The length of the cable between each panel and the junction box should be calculated to ensure that the correct cable size is used. 4. Number of strings: The number of cables that are needed for each configuration should be determined based on the number...
Expert experience with home/office security controllers. Want a cheap Programmable Controller with 3G/4G enabling multiple sensors, cameras and alarms. Basically if a sensor is triggered I want the camera in the same zone to take a video and send to the cloud over 3G/4G. Its an IOT programmable controller. There are many in the market but I am looking for a price sensitive controller. Ideally want a controller that is expandable with regards to sensors/cameras/alarms etc I believe this can be sourced but if not, I'm open for someone to develop it. timeline is 7 days
I need a soldering job USB port has come off cleanly from a circuit board. I need to bring this to you and have you do the work. I don’t really want to post away if I can help it.
I need to develop pressure sensor based coding for ESP32 mcu. Here, I am planning to use US9111 pressure sensor with mcp3421 ADC converter. I want to measure +5PSI to -5PSI pressure value, with auto zero calibration. When there will no pressure on the pressure sensor that must be zero value at the initial condition. It should be strictly maintain. It can be set by auto zero calibration. I want to measure pressure precisely, so you need to do the coding with exact calculation.
