Especially in old vehicles, electrical installation is a big problem, due to vehicle age, usage period etc. there are voltage problems. Especially in the chassis, oxidation, oiling, aging of high current cables etc. The Japanese have offered various products in terms of grounding. I decided to apply the system in my vehicle, the first part…
15 channel Vu meter circuit with peak hold or peak hold feature. It can be done with PIC16F1508, PIC16F1509, microcontrollers. I powered the PIC outputs with mosfet and drove strip led. You can use cob led modules or 12v lamps instead of strip led. You can also use 220V lamp with MOC3020-TRIAC module. I couldn’t…
DIY Layout Creator (DIYLC) is a special software designed for hobbyists and electronics enthusiasts to create circuit layouts on breadboards, perforated boards, PCBs and point-to-point wiring. It provides an intuitive, drag-and-drop interface to place components, arrange connections and visualize circuit designs before assembly. It allows users to design layouts with precision and clarity with its…
Open source USB PIC Programmer project for Arduino (ATMEGA328) based PIC MCU. Programming can be done with minimum components and ICSP connection for Atmega328 (arduino nano/uno) based PIC microcontrollers. You can also add new PIC models yourself, for this you need to edit the “pic.xml” file. Edit the values inside the “name” tag to add…
What is a Negative Ionizer? Air Purification and Ionization Technology A negative ionizer, also known as an air ionizer or ion generator, is a device designed to improve air quality by releasing negative or positive ions into the air. Using high voltage of approximately 5 kV, negative ions are produced, while positive voltage generates positive…
The charger ensures that the battery is charged with a constant current and then recharged after the charging current is reduced. The circuit consists of a full-wave rectifier, a current balancer and a charging current sensor. The current stabilizer works on the principle of limiting the current of the voltage stabilizer. The charging current decreases…
Devices made with NE555 for tacho feedback, optocoupler insulation, DC motor, washing machine motor speed control, lamp etc. control. Various motor control projects made with NE555 timer integrated circuit. You can control not only motor but also lamp or LED brightness. In addition to projects that can provide low voltage 5A-10A power between 12VDC 30VDC,…
The small amplifier consists of 3 transistors and passive components. It can deliver 400mW power at 9VDC operating voltage, speaker impedance is 8-OHM. The input signal is between 200mV and 2V. The quiescent current is adjusted with the R10 50K trimpot. When the amplifier is idle (without a speaker connected and input signal) the current…
