Is there an easy way to freely connect several music sources and their multiple receivers at home? Yes! Even if entire environment should be integrated with a COAXIAL-SPDIF switch for the audiophile sound quality? Sure, recently I built the switch that can do that. But now it's time for the main question, is there the easiest and most intuitive way in the world to manage required connecions? To allow anyone seeing it for the first time to control it without any learning? Of course, now there is! All I needed to breathe a new life into my music center is the HMI panel from Elecrow.

Using this electronic circuit, a very simple pulse generator can be made, using a 4066 circuit.

Here is another project with LEDs

A simple circuit with just eight components

Build a miniature DIY FPV drone that operates fully on Arduino hardware for a fun learning experience and thrilling living room racing.

In this project, we will build a tiny internet clock connected to your wifi to get time from NTP servers.

“The Cyber Clock” , A rechargeable battery-powered 1.51-inch transparent OLED clock with accurate internet time and date. It can also measure your room temperature and humidity from an onboard sensor. It can show the battery percentage as well, with a fully 3D-printed Cybertruck body. It also comes with rollable wheels so you can play with it. It is also possible to lock the wheels by tightening screws so it wouldn't fall from the desk by accident !.

The TEF6686 radio module is intended for AM/FM receivers for cars. This time I will present you a way to make a portable DSP radio with this module controlled by an ESP32 microcontroller.

A few simple Arduino examples of using this low-cost compact esp32 + tft touch display module.

Identify the faulty components via anomalous sound detection and diagnose ensuing cooling malfunctions via thermal visual anomaly detection.

Identify noxious air bubbles lurking in the substrate w/ ultrasonic scans and assess water pollution based on chemical tests simultaneously.
