RTLINUX research the linux RT patch for the Raspberry PI kernel (kernel version >=5 so not 4.19) and make a setup with a Raspberry PI proving that the Realtime Patch is necessary to achieve a timing goal. Can you guarantee that an RPI with or without load always responds within 1msec after detecting an event, even if it is 100% busy with other tasks at that time? Use public RT measurement tools to demonstrate that with the RT patch the system may or may not slow down (?) but can process a certain input with 100% certainty. Comparing Cyclictest results between RTLinux kernel and regular os kernel is enough. Compile and configure the kernel source code yourself and change the local "uname" to show your name when you do "uname -a". EXTERNAL INTERRUPT Use of external in...
I have pt100 temperature sensor signal connected to plc put the signal is not stable as there is many noise come from vfd so I need low pass filter circuit to enter the pt100 signal on it to make filter of any other noise
Need help on digital circuits, With good experience in this subject, JK flip-flop counters, Should be able to do the flowchart then design the digital system by drawings. Price will be discussed if you are able to do only one of those parts. Thanks.
i want to design a Microgrid with pid controller (Pso fuzzy pid, fuzzy pid, classic pid) in matlab to reduce frequency.
We need to make a gerber file for our pcb setup. it will be to contact 16 spring contacts and a set of two square eights pin contacts. :) The last two photos is of the original pcb we are trying to replicate. the problem with this one is that it only has eight spring contacts and only holds a sample that is 25x25mm we need it to have 16 contacts instead of eight and it being able to measure 8 points of a 100x40mm sample. the distance between the spring contacts should be 1cm center to center side ways. See the photos if you have any questions or send a question thru here.

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.

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...

It is necessary to connect (write firmware) the nrf52840 microcontroller to android phone using Bluetooth Long Range (Coded PHY). It is necessary to control (turn on/off) the LED connected to the microcontroller from the phone.
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...
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.
I need someone that has knowledge of this, to draw a graph from serial input which will be from an ADC on the MCU and given to the communication port via RS232.

We look for an implementation of Art-Net 4 and RDM based on our implementation of DMX. We are using a Cortex-M 4 MCU (Artery AT32F-415 RCT6 MCU) The AT32F415 Series Reference Manual V1.04 can be found here: The implementation should be as hardware independent as possible, therefore the implementation of Art-Net is planned on the cortex-M 4 MCU and the UDP data from the ESP module is being transmitted using throughpass and SPI link. This is the specification of RDM: You can use various open source implementations for our implementation. This is an example for a RDM implementation: Similar for ArtNet: An implementation of DMX is being provided. Design and Implementation Constraints The software should be programmed in Standard C. The IAR extensio...

The scope of work is in the attachment. A few things we need equal run time on the 3 Chillers. For example Chiller 1 runs 80% of the time Chiller 2 runs 15% of the time Chiller 3 runs 5% of the time We would like the chillers to switch from chiller 1, 2, 3 cycle operations to 2, 3 ,1 cycle to a 3, 2, 1 cycle in operation then back to 1, 2, 3 cycle. We need a similar situation with the Supply Pump and Backup Pump equal run time like the chillers We need a similar situation with the Circ. Pump and Backup Circ. Pump equal run time like the chillers As for the auto switch over for the Circ. Pump to Backup and Supply Pump to Backup is a case of failure on the main pump this is controlled by a pressure switch on mai...
