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

Invisible indoor pollutants? This ESP32 IoT node (AP mode) reveals them—TVOC, eCO₂, temperature, humidity rate —via its own Wi-Fi dashboard.

Dedicated to those who seek to merge technology and decoration, in this project we are going to integrate CrowPanel E-paper into Home Assistant

Build a Digital Timer Switch that allows you to switch devices on or off on a specified schedule, e.g. your garden sprinkler or lights in your home. This Digital Timer Switch will always have accurate time since it synchronizes its clock with an internet time server. No need to adjust the clock for daylight savings time or to set it after a power outage. Furthermore, the large display makes it easy the set or change schedules.

DIY off-grid terminal using Arduino Mega, TCM3105 modem, GPS, and error correction for resilient text communication.

“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 !.

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.
