    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

    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.

    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...

    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
