“AM Radio transmissions are based on a carrier signal which is modulated by the audio signal. It’s a very basic principle but prone to noise from the environment. Using the ESP32 it is really simple to generate an analog …
“The question you are probably asking is “why are you making another remote thermostat?” The answer to that question is, I had to, and the market smart thermostats are too expensive. Fair warning, this is “proof-of-concept” build that would require …
“The Home System 3000 is a device that uses an Arduino, a temperature sensor, a piezo buzzer, an optical detector/phototransistor, and a servo to display ways to improve home energy efficiency.”
“In this guide we’ll take a few simple parts, add some not quite as simple code, and build an adjustable waveform generator (aka frequency generator). Using a rotary encoder push-switch, we’ll select one of multiple waveforms, and using …
“I found the personal compass project at Instructables.com quite interesting. Basically, a personal compass works like a regular compass, but instead of pointing to magnetic north, it points to a particular location of personal interest. Maybe it is pointing …
“It may not know who you are. But it will look for you and it will find you. And nothing that comes in its way will be spared by it. It is none other than the determined and precise Line …
“A few days ago I started playing with some idea I had from a few weeks already, using a Raspberry Pi Zero W to make a mini WiFi deauthenticator: something in my pocket that periodically jumps on all the channels …
“Buildroot-based puredata synth, using the nanopi neo core and a CM6206 USB soundcard DESCRIPTION I saw the Organelle, and I really wanted one. They released their software as open source, but not their hardware. I decided I would just figure …
“Hi Makers, Hi makers, We see that you like our previous project “ANIMATED RGB WALL CLOCK”. Link is here. It was an honor for us. After a long time, we are again with a CLOCK PROJECT. And now, we offer …
“Servos (also RC servos) are small, cheap, mass-produced servomotors used for radio control and small-scale robotics. The are designed to be easily controlled: the position of the internal potentiometer is continually compared to the commanded position from the control device …
