Quick On-Board Junction Tester
Short circuits or broken PCB tracks can be easily identified using a multimeter. However, this tool may yield inaccurate results when assessing the efficiency of a transistor or diode unless the component is unsoldered and removed from the PCB. Additionally,...
5 mA S METER
The circuit designed for a 5 mA meter movement utilizes a two-stage voltage amplifier comprising transistors Q1 and Q2. An emitter-follower output stage, represented by transistor Q3, functions as an impedance-matching stage. The audio frequency (AF) input for an S-9...
Starting Capacitors
Instructions for electric motor start-run capacitors include the use of starting capacitors for air conditioner compressor motors and other electric motors like pumps. This involves diagnostic checks for start or run capacitors, including how to use a volt-ohm meter (VOM)...
dyi setup and debugging guide
This page discusses the differences between assembled Open USB FXS dongle boards and DIY boards. While the assembled boards are fully tested and quality control approved, DIY boards may encounter various issues during assembly. Fortunately, most of these issues can...
Capacitor Power Supply Circuit
One of the major problems that must be addressed in electronic circuit design is the generation of low voltage DC power supply from mains power to energize the circuit.
In electronic circuit design, the conversion of mains AC voltage to a...
How the capacitor works (in a debouncing circuit)
Understand why the LED does not light up, as the capacitor appears to be bypassing the switch. When the capacitor is fully charged, it does not conduct electricity. Although the individual is a beginner, after 20 hours of studying various...
testing ddl s circuit
A guide will be posted on how to test a DDL circuit before integrating the LD. The process aims to ensure clarity and accuracy throughout.
To properly test a DDL (Direct Drive Laser) circuit before adding the LD (Laser Diode), several...
Digital-ProfiLab 4.0
Digital-ProfiLab was designed for measurement and control applications, combining features like circuit and logic simulation, front panel design, and hardware control to one powerful tool. Incoming signals from external devices may be processed and displayed. A circuit editor is used...
Help me Understand this Circuit Schematic
The roles of capacitors C1, C4, and C5 in a circuit may not be immediately clear. Capacitors on the power rail help to smooth out the signal by reducing current ripple, which can be observed using an oscilloscope. Resistors R6...
