Creation of a small PCB for charging and powering a single USB A port. What I would like to have designed for me is a PCB that enables charging of a 3.7v battery through USB C, and outputs power to something that can be soldered to a USB A IO. The USB A output will only be supplied power when a button is pressed, and power will stop being supplied after 5 minutes. The PCB will need to include battery protection, and deep discharge protection. In short, this PCB will be connected onto an already existing PCB, that should only receive power for 10 mins after the button is pressed.
We need an electronic circuit that can convert AC signal into a train of pulses of 250 V (offload). The output voltage should not be less than 200 V while on-load (short circuit) condition. the shape and duty cycle of pulses is shown in figure attached.
Hi! I have a project for you guys! Here is the details: I want a system with an LED matrix. It should be able to display text and images that scroll past on an LED matrix. It must be able to be controlled remotely from the phone. This means I need a mobile app coded in react native connected to an MQTT server then send RGB message from the app. Feel free to use extra components to style the "prototype" - but I have to have these components myself. The solution must be connected to a cloud service (ThingSpeaks, Blynk, etc.). I need documentation of the entire solution, from microcontrollers, to cloud services and presentation of data and Fritzing. I also need a video of the solution. I should be able to wire up the entire project based on the documentation alone (so please simpl...

I need to detect the number of rotations of a spinning magnet. I have measured the magnetic field strength oscillating around += 0.9 Gauss (see attachment). Most hall effect sensors with built in amplifiers and comparators don't have operating points in this range so I need to design one using an analog output hall effect sensor and op amp. However, I'm open to other design suggestions. Requirements: - Digital output indicating a rotation of the magnet - Low power (~50 uA @ 3.3v) - Minimal part count - Low cost part selection - SPICE simulation or some kind of verification of design Example design: Analog hall sensor (e.g. DRV5053) -> Amplifier -> Comparator with hysteresis (e.g. TLV320x) -> Digital output

TI IWR6843AOP uses out of box demo that sends the radar data via serial. We need to change that to CAN FD.
It has a lot of rust damage in the battery area, will need replacing. Shouldnt be any other issues but a “tune up” of sorts is probably necessary.
We are a startup US company selling a custom product with an electric motor. We created an add-on device that receives CEC info from a TV and controls the motor with RF signals. We have all designs and firmware for our RF device completed, prototyped, and tested. The only part of the design we do not have yet is a 3D print file for the outer plastic housing. We are looking for an electronics manufacturer to produce our RF device for us. Small batches at first, but hopefully larger amounts as we increase sales of our product.
PART_1 I want to control an Arcus DMX-UMD-23 stepper motor. Here is the link to the stepper motor manual and labview software. This motor has a built in integrated stepper controller and can be controlled via a usb port. 1. we want to control the motor via the usb port 2. we want a screeen display switch to send the stepper to "home", home is a limit switch. 3. we want a screen display "switch" that allows us to choose either clockwise or counterclockwise rotation. 4. we want to make changes in the speed of rotation (i.e. the step size), so we need a control on the screen to do that by choosing the step size. 5. we want a box on the screen that given an input of "X steps", when we press the button, the stepper moves that amount of steps. 6. we want...

I have a Mini pixracer, and a raspberry PI4b. I am also have QGroundControl on my host machine. I would like to connect via either UDP or TCP for remote commands. I have this configured with MAVProxy, however it says waiting for heartbeat. Also, when FC is plugged in my Pi keeps cutting off and on.
I want to create an electronic version of backgammon. A board that players (users) can drag counters with their fingers to the right spot. I need to find a software developer that can handle this. Details will be submitted to the right candidate.
I’d like a unique and beautiful design for a device. You don’t have to digitize your sketch, just sketching your design by hand is enough for me. Of course, if you want to digitize it, then that’d be a great plus too. The device is simple: you slide it up to reveal the 3.5mm jack, the middle position hides it, and if you slide it down it reveals the usb plug for recharging the device. This device should have at least one button for turning it on and off. It might have a volume up and down button, but only if it makes the device look more beautiful. Lastly, it needs a 3-4 dot battery indicator above the power on and off button. That’s the basic requirement. You’re free to get creative with how you imagine this device will look but keep these basic requiremen...

Tentative title of the article No.1: The problem of setting operation parameters in digital relay protection of distribution networks. The main idea of the article: in the digital relay protection and automation terminals, the settings are set in almost the same way as in analog electromechanical relay protection devices. This is an atavism. In digital relays, it is possible to refuse current-dependent steps, a limited set of types of characteristics and set an unlimited number of current-independent steps (conditional settings), you can set separate settings to busbars in directional current protections, ... Illustrate this using an example in Automatic Relay Protection ARP. Preliminary title of article No.2: Development of an algorithm for formalized setting of the setting area of curre...

I’m looking forward to design a robust AC input filter for HiLink AC DC converter in which an AVR project is running. And I would like to add some prime features like inrush current protection, AC line transients / spike protection as well as inductive load back EMF protection which may sometimes reset the microcontroller. Please note we have only phase and neutral, so earth connection for the filter circuit. Please find the attached file of the proposed project.
Hi, I have programmed an imc controller for a mimo nonlinear system in Matlab simulink. The system has 3 outputs and 3 inputs. The control runs so far. However I have 2 problems 1. 2 outputs are controlled to the setpoint. However, one output does not reach the setpoint. x1 does not reach u1. 2. if I add a disturbance, the system does not control and the simulation hangs. Here I noticed that the choice of the filter is important. However, I can only control one output with the correct choice of filter. x1 does not reach u1 and x3 does not reach u3
Typhoon HIL is real-time simulation platform like simulink . I have made model for induction motor and its working fine . The physical device is working fine and sensor is giving speed and torque signal at digital speed PWM I already converted and work fine. The torque Problem still remain . I couldn't able to convert torque signal coming from sensor into torque value in software.
