Two simple local projects to introduce you to the basic finctions, and some of the possibilities of this Arduino Kit.

Voice Master Board by Next Builder

Detect USB Killer flash drivers and prevent damage to hardware.

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.

“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 !.

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

Effortlessly monitor your home's energy consumption with the DIY Smart Powermeter, seamlessly integrated with the user-friendly Home Assistant platform. This powerful project provides real-time data on your household's energy usage and offers the added convenience of a snapshot of your grid's status whenever you open the electric closet, thanks to the 2.9' e-paper display. Featuring an integrated 230VAC to 5VDC regulator, the ESP32-S2 efficiently harnesses power from surrounding wires for optimal performance. The Smart Powermeter supports up to six different CT clamps, with or without a burden resistor, allowing for versatile monitoring options. Additionally, it can measure ambient temperature, giving you comprehensive insights into your energy consumption and surroundings.
