In this project we see how to build an IOT-based dust monitoring system that can measure surrounding dust, send data over the Internet, and monitor the long-term value graphically. We use a Sharp gp2y1014au0f particle sensor which uses an IR LED and when the particle enters the sensor, the light bounces back to a photodetector….
Voltlog is hacking his car console through the CAN bus. According to the author, for his projects, the available CAN bus interface cards are somewhat lacking. So he designed his own wireless CAN bus hacking and development module called ESP32 CanLite. The project is published as open source and the files can be extracted from…
In this project we see how to build a measuring wheel designed to be used over distances where rulers and tape measures are no longer practical. Even if it uses a rotary encoder with only 20 steps per revolution it can still provide good quality results by measuring, for example, the size of a room….
With this project we will see how to make a solar powered wireless weather station using an ESP32 WiFi module and some common weather sensors. The weather station is fully solar powered, so you don’t need to worry about external power. It can be installed in a remote location without having to lay long cables…
In this project we see how to build a logic probe, that is a complete, simple and effective instrument that allows you to measure digital logic levels 0 and 1, both in TTL and CMOS technology. The maximum accepted level is 10 volts but CMOS can reach up to 18 volts (however best avoided). To…
Google Glass will go down in history as the first pair of smart glasses to hit the consumer market and also one of the most infamous tech flops. Kevin Bates tried to build a pair of smart glasses that were more compatible with hackers and wallets, given the price of Google Glass, and the “Arduglasses”…
paperd.ink is a 4.2″ e-paper display coupled with an ESP32 microcontroller. It’s open-source, fully hackable and all the PCB and 3D printing files are available on our Github repo. It’s low power so you can run it for a month on a single charge. Update wirelessly using WiFi, Bluetooth. Display your calendar, to-do list, weather,…
With this project you can customize your Computer station with DIY ambient lights, using a LED strip controlled by any ESP8266 based board. The color of the strip will be controllable from a smartphone and, like a home automation device, automations can be set to change color at certain times of the day or after…
If you often use keyboard shortcuts in your work or the key combinations are so complicated to remember, then this project is for you. Aaron Peterson created a touchscreen controller aimed at streamers, but there’s nothing stopping us from using it for other programs. In fact, the controller sends different key combinations in order to…
In this project, we will see how to turn any decorative object into an IOT smart device. Specifically, a plant pot was chosen and it was transformed into a device that sends movement notifications. The heart of the project is an ESP-01 WiFi module for wireless communication and a PIR sensor to detect movement. An…
A dimmer is a device that allows you to modulate the alternating voltage to be given to a load. In this project, an ESP8266-based dimmer was created that can easily control AC loads such as motors and lights. It has the power to handle more than 1200 Watts and it is a project that can…
This project aims to monitor the temperature and humidity in a room, through a compact and cheap device, powered via USB and which sends data to our smartphone through WiFi communication. The circuit consists of an ESP8266 module, a DHT22 temperature and humidity sensor and a 3.3V voltage regulator. The ESP8266 module will connect to…
