PLL FM 8W transmitter circuit is an RF project board with digitally adjustable frequency in the 88-108 MHz band, controlled by a TSA5511 PLL synthesizer and PIC16F84. The circuit uses..

One of the most important problems in electrode heater systems is that the current drawn also increases as the liquid temperature rises. The system, which starts operating with low current..

Recoil creates a short-term but very sudden acceleration effect in firearm or simulation-purpose mechanical systems. To measure this effect, in practice it is often more suitable to use a high-speed..

No need for a key, card, or password. You can operate it simply by using your fingerprint. In this project, a very simple fingerprint-based access control system was designed using..

A difficult-to-implement 3-phase inverter project. It can provide inspiration for different projects, and its documentation is very good. Full project files prepared with Altium Designer, heatsink 3D drawings, STM32 source..

The Battery Capacity Meter allows you to measure the capacity of any battery or accumulator; it can also be used as a precise voltmeter, milliammeter, and power meter. It discharges..

This is a simple circuit for creating electronic music boxes, doorbells, etc., using ringtone sounds. You can build this music box circuit with very few materials. In this project, a..

During the PCB manufacturing process at home, shaking the container holding the copper melting chemical accelerates the melting process. An old computer DVD drive is disassembled, except for the cover..

Control of a 108kHz ultrasonic water atomizer with PIC12F1840. A high-power nebulizer crystal circuit is designed to operate 3 atomizers simultaneously. The ultrasonic water atomizer device has 3 different operating..

This system uses an LED strip with 80 WS2812B chips. One LED chip lights up every 0.5°C, and the temperature ranges from -5°C to +34.5°C. Each chip contains one red,..
