    We call on all electronics makers to develop a working prototype of a launch speed indicator we have with us. The launch speed indicator has to sense a moving shuttle passing nearby it with two hall sensors. The LSI design, programming and testing have to be done. The LSI would need to log the speed data which shows up on a LED display after each possible also the log the time date of the should have two buttons for powering on and off of the LSI and selections.

    I plan to use a TPS54283PWPR from Texas Instruments in a project I am working on. I need an experienced engineer to help design my schematic and to ensure I have not made any silly mistakes (before I commit to the PCB) - alternatively, if this proves to be the incorrect part I will need help to identify alternative. All I need is a reliable DC DC converter with 24vDC input and output 1 = 5v at about 2 amps and output 2 at 3.8v at about 1.5 amps (I'm struggling with the maths in the datasheet)

    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.
