LASER TRIGGER FOR CHRONOGRAPH
https://www.electronics-lab.com/laser-trigger-chronograph/
“pinko” build a laser trigger for chronograph using PIC18F2550 and LM393 comparators. He writes: I finished this laser wall trigger for my HIGH RESOLUTION AND ACCURACY CHRONOGRAPH. The purpose of this device is to generate the trigger start and stop impulses for my chronograph as soon as an object disrupts any of the laser beams. […]
A 400W (1kW Peak) 100A Electronic Load Using Linear MOSFETs
https://www.electronics-lab.com/400w-1kw-peak-100a-electronic-load-using-linear-mosfets/
Kerry Wong built a 400W/100A electronic load using linear MOSFETs. He writes: I bought a couple of IXYS linear MOSFETs (IXTK90N25L2) a while ago to test their capabilities when used as electronic load, and the result was quite impressive. So I decided to build another electronic load using both MOSFETs. As you can see in the […]
Digital Potentiometer using Optical Encoder – 10KOhms
https://www.electronics-lab.com/digital-potentiometer-using-optical-encoder-10kohms/
The primary application of the project is to replace the mechanical potentiometer with optical encoder which is long life, accurate, smooth in operation. The simple project has been designed around LS7184 quadrature clock converter IC from LSI semiconductor, AD5220-10 Digital potentiometer from Analog Devices, and optical encoder from Burns. Quadrature clocks derived from optical encoder, […]

Harmonic Drive & Brushed DC Servo Motor Driver
https://www.electronics-lab.com/project/harmonic-drive-brushed-dc-servo-motor-driver/
The SERVO Motion Control Board is maybe the fastest and lowest-cost way of getting your DC servo motor up and running. The clear, explicit documentation and the Windows test utility program take the mystery out of servo motor control. The board is designed for easily adding additional axes of control without flipping dip switches or […]
How to Setup an LCD Touchscreen on the Raspberry Pi
https://www.electronics-lab.com/setup-lcd-touchscreen-raspberry-pi/
circuitbasics.com has a tutorial on how to setup a LCD screen for Raspberry Pi. In this tutorial, I’ll walk you through the process of installing an LCD touchscreen on the Raspberry Pi, step by step. Many LCD touchscreens for the Raspberry Pi include an image file that you can write to your SD card and get […]
CMOS-TTL QUADRATURE ENCODER USING LS7084
https://www.electronics-lab.com/cmos-ttl-quadrature-encoder-using-ls7084/
The quadrature LS7084 Module is a CMOS quadrature clock converter. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7084 are converted to strings of a Clock and an Up/down direction control. These outputs can be interfaced directly with standard Up/Down counters for direction and position […]

LTC4380 Overvoltage Protection
https://www.electronics-lab.com/ltc4380-overvoltage-protection/
Thomas Scherer @ elektormagazine.com writes: When it comes to protecting sensitive circuitry from potentially damaging over-voltage spikes and supply surges we usually resort to networks of coils, capacitors, resistors and suppression diodes to iron out the transients. The LTC4380 low quiescent current surge stopper IC from Linear Technology goes about it in a different way; […]
