Glue stck torch
This project, developed around 2005, involves constructing a torch using a glue stick, which conveniently accommodates an AA battery within its plastic casing. To create a functional battery holder, contacts for both the positive and negative connections are necessary. The...
5V / 2A isolated switching power supply circuit diagram
The circuit diagram includes an input filter capacitor C1 and a primary clamp composed of VDz and VD1. The resistor R1 is connected to the control terminal. C2 serves as a bypass capacitor. The TOP414GC-S is connected in parallel to...
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...
Crescendo ampilifier elektor1982
The Elector Crescendo was the first DIY amplifier that was not a kit. The design was sourced from the Elector magazines available at a local library.
The Elector Crescendo is an innovative audio amplifier designed for DIY enthusiasts. It features a...
Homemade Metal Detector Kit
A simple home project can quickly become problematic if it encounters electric cables, gas, or water pipes, or the central heating system. Using a metal detector allows one to check for metal objects within walls, ceilings, or floors beforehand. An...
Switching Improves Regulator Efficiency
In this circuit, a full-wave bridge is switched to a full-wave center tap to reduce regulator dissipation. SCR D6 switches between configurations. When D6 is off, the circuit is an FWCT rectifier using D1, D2, and D5. It applies 17...
MePADS
If you are considering building the Desert Ratt 2, it is advisable to read all the accompanying text, as it contains relevant construction details. Engaging with the comments and replies can also provide additional insights, as previous blog posts have...
A control circuit reversing braking and reverse grading speed control function
The circuit depicted in Figure 3-168 utilizes a controller for speed grading and reversing control. A reverse brake is connected to the rotor circuit through an overcurrent relay, labeled KI, for control. The current relay KIi to KI3 serves as...
Switching Circuit
This switching circuit functions as a bank of interlocked mechanical switches. Activating one of the buttons latches its corresponding output while unlatching a previously selected output. A pair of inverters creates a latch for each output. For instance, pressing button...
