A couple of weeks ago, I received a nice comment from one of the community judges for the Hackaday contests and was amazed when I also noticed that he added TrillSat to his How to Enter a Project into a Hackaday Contest page as an example of what to...
Overview Problem: A ringing doorbell at the wrong time can wreck meals, naps, or a once in a life time moment (queue dramatic music). Furthermore, when you're away, how can you know whether you've had any visitors, packages, or neighbors stop by. Solution:...
INTRODUCTION I need quite a few solar panel sun trackers to generate as much power as possible from 60 solar panels. Why? well, we bought a farm in Spain, 120 acres of olive tree garnished paradise. I'm building a large, off-grid property...
Summary I added timezone support, so the clock can display the local time. Deets NodeMCU doesn't have any timezone support -- what is there is all UTC. So I'll have to write that myself. Plus, I will have to deal with summer time/standard...
Story In this project, I will show you how to make IoT based Pulse Oximeter using ESP32, MAX30100, and Blynk Application.we can monitor those values from anywhere in the world using the Blynk IoT cloud platform. As there is an availability of online...
Hello guys, I made want to make a 7-segment display. But this time with bigger digits and RGB effects. Because this can be used to display some readings like Clock with Nodemcu, temperature monitoring using Arduino. Also, with an option of color changing...
In my last tutorial I created a NodeMCU based Duino Coin Miner. It is an awesome little miner that sits on my desk and mines few cents a day. However, adding these miners to my home network choked my WiFi router. Home Appliances and Smart Devices...
Everybody loves a video so here's one to start with before we get to the boring fascinating details. There are many protocols out there for communicating between computers, and other computers or peripherals. A subset of these are common enough to be...
TL;DR I got the Pro Mini XL working with the Arduino-LMIC library. It’s performing OTAA to The Things Network over LoRaWAN. And it’s reporting temperature and humidity measurements from an SI7021 sensor - with 80% program memory to spare! (Note: There’s...
Step 1: Gather Your Components Laser XY Scanner - BOM I usually like to source my parts from DigiKey, but the low-cost options on Amazon are hard to beat sometimes. This list is just one of many sources for each component in the BOM. There are of...
In this IoT project, I have shown how to make an IoT-based Home Automation with Arduino IoT Cloud & Alexa using ESP32 to control 4 home appliances with voice commands. If the internet is not available, then you can control the home appliances manually...
Hello guys, today we are going to make this RGB ring using Neo pixel led's. we will learn, something new about Neo pixel, how to operate them, how to show different animations and how to make your own RGB neo pixel ring. In last we will control them...
Supplies Part of the fun of this one is that we can repurpose some old stuff you may already have on hand, but we do also need some electronics. And hey, even these may be part of an old project in need of repurposing as well! I've provided affiliate...
Greenhouse, also called glasshouse, building designed for the protection of tender or out-of-season plants against excessive cold or heat. A greenhouse is a safe haven for plants. It reduces the accessibility of insects and animals that have the potential...
1. Description of the device The Rotating Display device comprises two primary units: a power supply unit and a display board (figure 1). Both are circular in design, with a diameter of 120mm, similar to the dimensions of a standard Compact Disk. The...
