Hello I have some old PCB boards that some...exists and therefor I can't buy them. I need to update these PCB boards by finding alternative modern components for these boards, and make sure that the new components works with this boards by reading very carefully the datasheet, create a circuit of the modern component and then test it. The person who will help need to: 1) To be very good and have some good practice in finding the right electronics components 2) To be very good in reading/understanding Datasheet for components that is used on PCB board. 3) To be very good in deciding the suitable circuit for the modern component, according to all recommendation from the datasheet and own experience Pls do not bid if you are not knowledgeable on all points above, so we s...

Develop a MCU+ADC based board, when a trigger signal reaches the board, it should sample (12 bits) 6 analog signals and read the value of a 4 byte counter on an external clock (25 to 50 MHz). The 6 x 2 bytes values of the 6 analog signals, plus the 4 bytes of the counter and 1-2 bytes for with the board identifier will be streamed via Gigabit ethernet as UDP packets (about 1000 x 20-bytes events in every packet). The board should sustain a trigger rate of the order of 1 Million per second or higher. This project should be implemented on a MCU, as it is to replace a similar board based on FPGAs. The MCU will read the external ADC (6 independent ADCS able of at least 1 Ms/s each, at 12 bits). A 32 bits MCU based on multi-core ARM at 1 GHz or more would be required to handle ...

microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip. Sometimes referred to as an embedded controller or microcontroller unit (MCU), microcontrollers are found in vehicles, robots, office machines, medical devices, mobile radio transceivers, vending machines and home appliances, among other devices. They are essentially simple miniature personal computers (PCs) designed to control small features of a larger component, without a complex front-end operating system (OS).

I have the cod but it still needs some modifications and I have the circuit simulation. 1st one is automatic you can enter the time for mixing and then enter the time for extruding by the keypad the time in minutes and then seconds 2st is manual in which you have to press the push buttons to start/stop and mixing and extruding the LCD will display the timer countdown for the remaining time in automatic or the state when it's manual + there is a POT-HG to control the speed of the motor the program should ask you first to enter the time for the mixing in minutes and then second after that the program should ask you to enter the time for extruding also in minutes and then in seconds the LCD will display the countdown in seconds in mixing the motor should run in clockwise and in ex...

I am designing a capacitive soil moisture sensor. It is based on the interdigital capacitor and will be manufactured on a PCB. I will need the formula(s), with a brief explanation, in order to calculate the total capacitance of the PCB probe (when it is on the air and when it submerged on the water). My aim is to use these parameters (along with the others parameters from the electronic circuit) with an optimization algorithm and find the optimal capacitor design. And then compare the theoretical values with the actual ones. Therefore, all parameters should be included, such as: - Number of fingers (N) - Length of finger (L) - Width of finger (W) - Gap between fingers (G) - Substrate dielectric (of FR4) - Height of substrate - Height of PCB trace - (and any other that I am not ...
