What is a PM Stepper Motor?
Hacker page by Mark Liu
What is a Permanent Magnet Stepper Motor? Permanent magnet stepper motors (PM) are rotated by a magnetic rotor core through interacting with a pulsed electromagnetic field generated by the stator.Permanent magnet step motors are generally two-phase,...

Different Types of Diodes
Hacker page by kellygreene0805
Diodes are electrical components with two terminals and one-way current flow. The diode's ability to only allow the electric current to travel in one direction is well-known. When you need to rectify a waveform, you can use a diode in a radio detector...

Hacker page by danjovic
User Jipe from MRC (and MSX Village) reverse engineered its Ninja Tap adapter to obtain the schematics https://msxvillage.fr/upload/pccm_ninja_tap.pngLuckly I was on the right track, being the most relevant difference the SI inputs of the 4021 being...

Common Problems and Solutions of Planetary Reducer
Hacker page by Mark Liu
1. the worn planetary gear tooth and gluing, pitting, grinding deviation and introduction (especially the pinion speed is very easy to wear) may cause vibration of the reducer. Treatment: timely replacement of severely worn gears. Generally...

How to commutate a brushless DC motor?
Hacker page by Mark Liu
Commutation principle of brushless DC motor A brushless DC motors are an electric motor with multiple permanent magnets on its rotor and multiple sets of windings on its stator. The speed and direction of the motor are controlled by controlling the direction...

A little forth music...
Hacker page by Andrew Clapp
This was too fun not to share. Today I was chipping away at t problem that I've been at for a few days, and it finally came together. The start, was the need to have a way of assigning the channel for ADC on the STM8L in stm8ef. This has...

Hacker page by max
Well, hello there, how nice to see you again. Everything we’ve talked about thus far has laid the foundation for what is to come. In the case of this column, this means we are poised to perform our first hands-on experiments with real electronic components....

Principle and function of electrolytic capacitor
Hacker page by Cecelia Anne
Electrolytic capacitors are commonly known as polarized capacitors, in which the anode has more positive voltage than the cathode. They are used in filtering applications, low-pass filters, audio amplifier circuits and more. Metals such as aluminum,...

Oh the difficulty of sourcing P-MOSFET in TO-92
Hacker page by Yann Guidon / YGDES
If you follow Yet Another (Discrete) Clock, you know this project uses quite a lot of MOSFET in the easy-to-solder TO-92 package. A bit less than 500, including about 300 N-FET (BS170 or 2N7000) and the rest are P-FET (BS250).The N-FET are OK: I could...

HOME ANEURAL INLEARN: The Autognorics Approach to the Problem of Defining Life. Many thinkers, past and present, have tried to solve the underlying nature of Life. Yet, no one has ever categorically expressed the exact concrete description of the nature,...

The Differences Between Open-loop Control System and Closed-loop Control System
Hacker page by Mark Liu
Automatic control systems are classified by the structural characteristics of the system and can be divided into open-loop control systems and closed-loop control systems. What is the difference between these two, this article will introduce them to...

Hacker page by alldigitalservicesforu
Arduino is a versatile and widely used microcontroller platform that allows hobbyists, engineers, and makers to create all sorts of interactive and automated projects. One of the reasons for the Arduino’s popularity is its expandability through the use...

4 Things You Need to Know About Phase Loss in Stepper Motors
Hacker page by Mark Liu
1. What is a stepper motor phase loss? The lack of phase of the stepper motor means that during the operation of the stepper motor, the current of a certain phase cannot pass normally, resulting in the failure of the phase to generate a magnetic...

Teardown time again: Woods 32555WD remote control outlet. Finding out how the channel is set (it's a little brutal)
Hacker page by mcu_nerd
As I've gotten tired (and/or lazy) about having to plug/unplug the outdoor Christmas decoration lights, I finally got an outlet that can be switched on/off via a remote. The one I got was labeled as a "Woods 32555WD, but there's no Woods logo anywhere...
