The project described here is a high-efficiency dual BTL class-D audio amplifier with single supply operations. The project was built using TDA7491LP13TR from ST. The low profile PCB design can fit in a small area, operating power supply 9-12V DC, Project supports single-ended or...

The circuit presented here is a 3W stereo audio amplifier with memory UP/DOWN volume control. The project is based on PAM8408 IC from Diode Incorp, a filter-less class-D amplifier with high SNR and Differential input that helps eliminate noise. Two tactile switches are provided to control...

Jürgen Mülle has posted details of re-implementing the 65C02 in an FPGA, in a pin-compatible format that enables you to upgrade old computers and games to a 100 MHz clock rate! Speaking about the project, Jürgen says: "The idea of implementing a CPU core inside an FPGA is not new,...

The OpenAirMonitor is an outdoor air quality monitor that is powered by solar energy and sends data over LoRaWAN and Bluetooth LE. It measures the amount of dust (PM1, PM2.5, and PM10), as well as the temperature and humidity. The monitor has a STEMMA QT connector, which means that it...
