Simple VGA/Video adapter with ATmega AVR

Even including labor, the actual cost of purchasing, stocking, assembly, assembly errors, more expensive PCBs (with additional holes and larger sizes), and the increased difficulty in tuning would likely result in significantly higher expenses. The analysis of costs associated with...

This circuit employs a thin piezoelectric sensor to detect vibrations caused by knocking on a surface, such as a door or table. It amplifies and processes the sensor's signal to trigger an alarm for a predetermined duration. The piezoelectric...

This is a straightforward X-Y oscilloscope design utilizing an ATmega324P microcontroller and two KAD0820 analog-to-digital converters (similar to National Semiconductor's ADC0820). The initial version of this oscilloscope was based on an AT90S4414, necessitating the use of external ADCs. Various...

The diagrams below illustrate the development of a simple modular radio receiver based entirely on circuits and devices studied during the Part IA course on Linear Circuits and Devices. This receiver may not revolutionize the market; however, it aims...

This document provides an explanation of a simple 100-watt inverter circuit using the IC CD4047 and the IRF540 MOSFET. The circuit is designed to be simple, cost-effective, and suitable for assembly on a veroboard. The CD4047 is a low-power...

An ultrasonic sound wave can be generated using an electronic circuit. This simple electronic circuit can produce an ultrasonic wave with a frequency range of 12 kHz to... An ultrasonic sound wave generator circuit typically employs a few key components...
