If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying ? I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on […]
ulibSD It’s a library for use SD cards in SPI mode with uControllers, entirely writtenin C. This library can work with SD cards and also has the possibility to emulate the behavior in a PC file (GNU/Linux) using the macro _M_IX86. It’s for debugging purposes. The data transfer is oriented to 512 byte size, remember

Recently I’ve found this piece of electronic on the dumpster, it was looking interesting – compact case with battery holder, LCD display, temperature and humidity sensor. It has also radio transmitter, but I’m not interested in it since I don’t have the receiver station. I decided to bring it back to life. It seems that
In this project you’re going to monitor the status of a door using an ESP8266. The goal of this project is to show the endless possibilities that this $4 WiFi module offers when integrates with a free platform that I’m about to show you. Before continue reading this project, please complete the following tutorials or use
This little Instructable will show you how to use a 320×240 pixel LCD screen connected to an Arduino Uno with a network shield too, to show stats for Youtube channels. I created this as I wanted to see how many subscribers and views I had on my channels without having to check Youtube 🙂 The
Monocle enables Alexa devices such as Echo Show/Spot & FireTV to view your network IP cameras & control them with a wireless PTZ controller. Story Amazon Alexa® (at least at the time of this writing) does not inherently support any direct integration with local/private network cameras running securely inside your network. Instead Alexa focuses on

The DFRobot Beetle is one the latest innovations in minimalistic Arduino technology. About the size of a quarter, and the capabilities of an Arduino Leonardo, this tiny guy can minimize your projects with ease without having to sacrifice functionality. After working with the Beetle, I am going to show you some tips and necessary tricks
LAKE WALES, Fla—Quantum dots are already being used commercially to boost the output and expand the color range of ultra-high-definition televisions, eliminating the need for the rare earth elements for which China as virtually cornered the market. Quantum dots, however, can also be used to absorb light to boost the output of photovoltaics, photocatalysts, light
In this project, you’re going to build an Android app using the MIT App Inventor software that allows you to control the ESP8266 GPIOs. First, watch the video demonstration To learn more about the ESP8266 use the following tutorials as a reference: Getting started with the ESP8266 ESP8266 web server with NodeMCU Flashing NodeMCU firmware ESP8266 troubleshooting
ESP8266 controlled with Android app (MIT App Inventor) Continue Reading
When I was working on the next version of Common Parts Library, I realized that it would be helpful to explain why you might pick one type of passive component over another. We started off by writing “How to Select a Capacitor” last month, and are following it up with a close look at resistors
