I am currently developing a battery powered DC variable power supply and I need a PCB created to control it. I would need it to have a buck boost circuit that could do 0vdc-60vdc @5amps as well have a current limiting feature for testing equipment, etc. & perhaps digipots to control the output voltage and current limiting digitally through the menu. I also will be using a TFT LCD to display a menu & to show voltages & current draw, so using an STM32 to drive & control all the logic would be preferable. Im not sure which batteries would be best to use in this so achieve the desired power outputs that I want so perhaps you may have some suggestions for batteries but for whichever batteries it would need a BMS and all protections as well with a USB C recharging circuit for re...

This project is based on ESP8285 microcontrollers and programming should be done in Visual Studio Code (PlatformIO) Background: This is supposed to be a monitoring system. It involves detecting sensor values at multiple locations (at least 25, with more to be added, on demand). Each sensor location is connected to an ESP8285 wifi board on UART1 (soft serial). All of the 25 individual wifi modules will connect to a central hub - which is another ESP8285 module. This central hub will be connected to a cloud server through a broadband router. It will send the data of all the 25 sensors to the cloud server. The cloud server will also reply back some data which needs to be transmitted back to the 25 sensor modules. Based on this data, the individual 25 sensors will perform some action, like ...

I need help creating a custom DIY bark repellent device. It can be based on Arduino, Raspberry or pure electronics - Raspberry and Arduino being the best as they can be easily updated or programmed. Anything I can find on the market are small toys without the much required power. It has to use larger loudspeakers - not the tiny kind you see in any bark repellent It has to allow change of frequency (as in adjusting for a specific dog/animal). From what I understood it has to emit ultrasonics around 20kHz-25Khz (in case of dogs) so it is not a such complicated device but I need someone to think about all these aspects and compatibility of the electronic pieces. I have very good coding skills and some basic electronics knowledge so I will be able to provide feedback and help with anything...

Hi Everyone, I’m looking for an experienced ESP32 SW engineer to create a wireless file transfer tool. I have an ESP32 connected to a Teensy 4.1 trough SPI and Serial port bus and I need to transfer some files stored on the Teensy SDcard over Wi-Fi. Each file is around 100MB so SPI bus is the only option and a fast transfer protocol is needed. The code to be written is divided in two sections. 1. Code loaded on the ESP32 to include a small webserver where the user can open a browser and look at the files available on the SDcard and select the one to download. The ESP32 will request to the Teensy to transfer the files (ESP is the SPI Master) 2. Code loaded in the Teensy 4.1 will negotiate with the ESP32 the access to the SDcard. The Teensy will also need to tell the ESP if is curr...

Siren for Police - Programmable Hello we have here a SDF104H from Axixtech Juluen in Taiwan, the problem is this siren have a controller with RJ45 with different buttons and more.

I have indoor grow tent, with multiple citrus trees, It runs an exhaust fan, 4 air moving fans, 4 lights, 2 heating pads, and an irrigation pump, I currently run most of the items off of a wifi power bar (geeni surge 6) and the exhaust fan runs via its own controller with temp and humidity settings. The irrigation pump is supposed to run off of a wifi based application (the app no longer exists) I am looking into the idea of getting a raspberry pie and running the entire system off of that with some programming. I would have to regulate on/0ff times for lights and exhaust fan and also integrate a run cycle for the irrigation pump. If anyone has any insight into this tye of system please lets start a conversation

Hello, I am currently working on a heating control project that uses an Arduino board and a motor-controlled valve to regulate the flow of hot water from a primary circuit to a secondary circuit. The primary circuit is connected to a source of hot water (fernwärme/district heating) that maintains a temperature between 60 and 120 degrees, and a permanent pump that can not be controlled or regulated. The secondary circuit is also connected to a constant-speed pump and the goal is to maintain a temperature of about 40 degrees. I have implemented a basic control logic using switch cases and if-else statements, but I am having trouble getting the system to accurately regulate the temperature of the secondary circuit. I have read that using a PID controller can help improve the performance...
