Requiero realizar la conexión automática entre dos ESP-01. Funciones deseadas: - Pulsar botón (transmisor-maestro), conexión automática entre el transmisor y el receptor - Mantener conectividad estable al estar cerca (1 o 2 metros) - Enviar a dormir el dispositivo ESP-01 (transmisor-maestro) para ahorro de batería. (siempre deben estar conectados) - Encender un led (receptor-esclavo) cuando se pierda la conexión (solo se debe perder la conexión si los ESP-01 están fuera de rango en metros)
Buenas noches a todos, quisiera hacer un control de asistencia de estudiantes que registre hora de llegada, hora de salida, registro de estudiantes (nombres - curso), capacidad de agregar o quitar estudiantes y registrar sus huellas, que genere un informe que se pueda visualizar en la computadora (sistema operativo windows), mediante wifi, para poder buscar si el estudiante asistio a la unidad educativa, y ver en que dias falto. para el proyecto cuento con: ESP32 dy50 fingerprint sensor arduino uno.
want to have pcb designed with parts available online to purchase currently. Circuit is available please see attached doc. The pedal element I already designed with 4 nos Strain guages. This circuit will give output to the strain guage bridge circuit and gets output in volts which will be applified by circuit and available for data recording. Rest information about circuit and functioning is available in attachement.
Design a low pass filter which I will tell you more precisely. The priority of the project is given to those who have the accuracy of work and high mastery of electronics and receive lower fees. (Altium Designer) Lower cost is preferred. Layout is required.

The PCB thermostat needs to run on 220/230V 50/60 hertz, it needs to have two NTC probes one for measuring water temperature and one for safety (excess water temperature shutdown), rotary, measure from +/-1 0-40 degrees Celsius, it needs to have built in contact suppressor.
I would need a quadcopter drone put together having motors, escs, battery, and so on without a frame and sent to me. Everything would already be connected together and ready to go ,without the need for calibration, using a remote control at the flip of a switch. The motors would need to be high torque and be as flat or least in height as possible. They would need to have the metal shaft already attached and preferably a threaded shaft. The bottom of the motor would preferably be flat too.
i am having a relay which communicates with this protocol IEC 61850
looking for PCB design experts with 4+ years of experience. Will share details through private chat. The designer should have the ability to get a complete PCB file from a DXF file.
The Controller is PIC16F628A, more details will be shared in private chat.
more details will be shared about my project via chat
Design pcb to house an esp32 module and associated electronics to make distance measurements from 10mm to 140mm. Accuracy within +/-10mm. The ultrasonic sensor needs to be mounted external to pcb via a connector. Do not want ultrasonic modules on pcb, u must design that circuit yourself. The esp32 will be going into deepsleep, so u must shutdown any current that will drain the battery. Pcb must accept battery holder. Deliver the following: pcb, schematic and libraries (kikad or eagle) Manuf gerbers Excelfile with bom (digiket, mouser or RS links)

I have a pinball machine with a suspected faulty PCM1755DBQ ship. I have the replacement chip but need it replacing on the MOU board. It’s a surface solder. This is a very small surface mount component that measures approximately 5 x 6 mm (including the chip legs).
Hi, I am looking for somebody who is experienced with the microchip VSC7514 to review electronic design and troubleshoot. We need somebody who is experienced with ethernet protocole. We currently have many items working but there is an issue as when the PC sends some frames to the VSC, nothing is answered. Thanks
I'm working on IoT project. I'm not very technical. I need help to write a python code to allow raspberry pi to automatically connect two Bluetooth devices to specific serial ports rfcomm0 and rfcomm1. and then I want the python script to automatically start on reboot. would require Video call to show everything in details. I might not be very clear about this so please ask me any questions.
Looking for Electrical engineer / Ph.D for signal preprocessing , classification (deeplearning)
We are looking for an arduino expert to write code for arduinos. Experiance with actuator, servo, stepper motors, various sensors, key pads, LCD screens, batteries, and other electronic components is essential.
Hi, I want to develop 10Msps, 1MHz arbitrary waveform generator. The device should have a PCIe interface to connect to Raspberry CM4's PCIe bus. The following components must be used. CH368, STM32F4 or G4. 10Msps DAC. Deliverable: * Hardware design (EasyEDA, KiCAD, or Altium) * Linux Driver * Demo Python CLI application Timeframe: Until before Dec starts
I have an ESP32 chip with the code attached. The problem is that it works perfectly when pairing it the first time, but when I restart the chromecast v3 or it unpairs or it also happens that it unpairs the remote control from the chromecast having to factory reset it.
We need an HVAC engineer to read the schematics and explain all the details in the schematic
Need to know Mplab Programming for PIC16F628A. Compiler is CC5 x compiler. Details will be send by chat.
Hi I need a custom antenna Bluetooth (2.4 Ghz), I have a design. The antenna has connector IPX-V1 + Wire + PCB (with ceramic antenna) I have a design of the PCB, and I choose the ceramic antenna, I need to somebody can tunning with 50 Ohm and SWR < 2.0 I can send the compent, to do the job. Thanks. Ricardo
