  • Long & Thin or Short & Fat?
  • Hacker page     by chipveres
  • Ferrite rod antennas (loopsticks) present a design challenge because of size, weight, and cost.  One of the fundamental questions is long or fat?  These gents have the answer:https://ietresearch.onlinelibrary.wiley.com/doi/full/10.1049/joe.2013.0126They...

  • A Life in the Day of MorningStar
  • Hacker page     by Morning.Star
  • I've led an incredible life, one too incredible to keep telling, so I'm putting it all here in brief. Buried among the rest of my stuff it will tell my story until I'm ready to write my book. One day I will, but until then. Born Jan 1967, same year as...

  • Small Signal Motor Driver
  • Hacker page     by Super Circuits
  • This article explains how you can build a small signal motor driver. A signal is entering the input of the circuit and is amplified with three transistors to drive a low current motor. This circuit can be connected to an AC amplifier. The AC amplifier...

  • STONE HMI ESP32 LINE COUNT AND ALARM
  • Hacker page     by 94754sakura
  • With the continuous development of a single-chip microcomputer, the counting equipment tends to be automatic. It needs an automatic technical device with real-time, high efficiency, and accuracy to meet the counting requirements of the modern production...

  • 6+ IDEs to debug the $2 STM32 BluePill
  • Hacker page     by Wassim
  • 2018 UpdateST gets AtollicYes, "almost 2018", update. Interesting to see as noted @Hamish with the link he posted, STMicro acquiring Atollic IDE that was classified in this review as the most efficient. That makes sense. VSCode rules overWhere...

  • Arduino Workshop-Simple Motor Control
  • Hacker page     by Mr. Sarful hassan
  • This tutorial we are going to Arduino Simple Motor Control, in one direction, using a power transistor, diode, and external power supply to power the motor and a potentiometer to control the speed. Any suitable NPN power transistor designed for high...

  • LCD Temperature Display- Arduino Workshop
  • Hacker page     by Mr. Sarful hassan
  • This project will be a simple demonstration of LCD Temperature Display using an LCD to present useful information to the user, in this case, the temperature readout from an analog temperature sensor. We will also add a button to enable the temperature...

  • Arduino Workshop-Using an L293D Motor Driver IC
  • Hacker page     by Mr. Sarful hassan
  •  In this project, we are going to use a very popular motor driver IC called an L293D. The advantage of using this chip is that we can control two motors at the same time, as well as control their direction. The chip can also be used to control a...

  • Arduino Workshop-Light Sensor
  • Hacker page     by Mr. Sarful hassan
  • In this project, we will use an LDR to detect light and a piezo sounder to give audible feedback of the amount of the light detected, a light-dependent resistor, or LDR. As the name implies, the device is a resistor that depends on light. In a dark environment,...

  • Arduino Workshop-Piezo Knock Sensor
  • Hacker page     by Mr. Sarful hassan
  • Today in this project we are going to create a Piezo Knock Sensor, A piezo disc works when an electric field (voltage) is applied across ceramic material in the disc, causing it to change shape and therefore make a sound (a click). The disc also works...
