“This is my second encounter with LM3886. I was pleased with the sound this chip produced the first time, so I decided to make another amplifier with it. The schematic is based on the schematic in the datasheet of the …
“the FIRST single-board DIY 8-bit personal computer with VGA, Ethernet and printer support, GPIO and CP/M powered! Meet my CRISS CP/M: the modern single-board 8-bit full-featured personal computer! Amazing functionality for the DIY device: it is not a …
“The project presented here is a dual AC to DC output linear power supply. This power supply provides low ripple low noise DC regulated output. Usually, transformer-based linear power supplies are considered very bulky and inefficient, but this power supply …
“The ESP32 Node is a development board for Wireless Sensor Network based on WiFi. It uses the ESP32WROOM3E module from Espressif Systems. Applications - Connect a Temperature Humidity sensor to monitor the Weather/Room abience - Use it to control relays and …
“You will learn how to create your own shield to create automation projects and to program your own ESP8266 ESP01. The ESP8266 ESP-01 is a great device for creating automation & electronics projects with the Internet of Things. In this …
“This is an Infrared Remote controlled motorized potentiometer controller. It’s an open-source project built on the Arduino platform and compatible with Arduino IDE for custom programming. The project consists ATMEGA328 microcontroller, IR sensor, L293D motor driver, ALPS Motorized potentiometer …
“This is a complete microphone signal conditioning project. Designed primarily for voice-band applications, this project provides amplification, limiting, variable compression, and noise gate. User-adjustable compression ratio, noise gate threshold, and two different fixed gains optimize circuit operation for a variety …
“Why wear a boring paper card to a conference when you can bring a cool and hackable one based on an ATtiny85? Programmable cards and badges are really good ice breakers at conferences as they’re a great way to …
“The project described here outputs 12V DC voltage from the input of 230V AC. The output current is up to 100mA. The project is based on BM2P129TF chip which is PWM method DC/DC converter with a built-in 650V MOSFET …
“This is an easy-to-build open-source Arduino compatible board that enables driving 8 RC servos over NRF24L01 RF Link. The project can be used as a standalone RC servo driver or 8 channel RF remote-controlled RC servo Receiver. An optional OLED …
