Build a Parking Sensor with the TOF10120 IR Laser Distance Sensor and a CrowPanel 3.5" ESP32 Display. A parking sensor helps you to avoid obstacles while parking, for instance, by measuring the distance between your car and the garage wall. This Parking Sensor accurately measures the remaining distance and shows it in big, color-coded digits. It furthermore features a set button that allows you to set the warning distance.

LedBox V3 is an ultimate, sound-reactive LED controller, compatible with 5-12V addressable LED strips (WS281x, SK6812, etc.), supporting 3-(data) and 4-(data/clock) wire signal protocols. Whether you prefer a plug-and-play solution, or you are a maker that loves tinkering with hardware, it offers the best of both worlds.

LaserProjector V2 is a battery-powered, ESP32-based laser XY scanner using stepper motors to deflect the beam. It has auto-homing functionality, and can be controlled wirelessly (Wi-Fi & Bluetooth).

Project #29 - DFRobot - Soil Moisture Sensor - Mk28

I am going to use this screen to create a touch panel for my home automation system.

Had some time this weekend and a desire to create something new and interesting, so went ahead and created an Arduino/NodeMCU based indoor dial thermometer.

This is certainly the simplest and cheapest object detection system that can serve perfectly for the presentation of the possibilities of this technology.

This is certainly the cheapest and simplest Internet radio that you can make yourself if you have minimal knowledge in the field of electronics, and all thanks to this universal and practical display module.

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 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.

Make a FilamentCase!! IoT FlamentCase!!

In the year 2021 I created a "Internet Hardware WatchDog" using NodeMCU which reboots my home router whenever there is an issue with the Internet. This device sits next to my router and happily takes care of it whenever it has a hiccup. This year, I wanted to extend the watchdogs horizon by adding an "Internet Status Notifier" that displays the current status of the Internet using an RGB LED.

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.
