In this post, we’ll take a look at interrupts and timers in microcontrollers. I will show you how to implement it with an Arduino and with an ESP8266 or ESP32. When an interrupt is triggered, the microcontroller will pause what it’s doing and immediately run an ISR(Interrupt Service Routine) before returning to where it left off before.
In this post, we’ll take a look at watchdog timers in microcontrollers. I will show you how to implement it with an Arduino and with an ESP8266 or ESP32.
Recently, I was using FreeRTOS on an ESP32, so I thought I’d make a post documenting it and showing you how to use it. FreeRTOS is an open-source real-time operating system used for embedded systems.
I started using Wireguard as a VPN to connect into my home network some time ago. In fact I wrote about it in this post about docker containers I run on my home server. It worked fine on my smartphone but when later I tried it on a laptop I got the following errors: Warning: the “Ethernet3” interface has Forwarding/WeakHostSend enabled, which will cause routing loopsRetrying handshake with pear because we stopped hearing back after 15 secondsHandshake for peer 1 did not complete after 5 seconds, Retrying
I’m going to make this quick post on how to fix the Creality slicer software crashing or freezing. Hopefully, it helps out somebody. I have the. 4.8.2 version but it might affect others too. This issue sometimes just appears out of nowhere despite not making any changes or even using the software.
In this post, I’ll show you how to make API requests from the ESP32 or ESP8266, how to set up a web server on the ESP and use AJAX to send/receive data and how to establish a web socket connection for bi-directional data streaming. These examples can be used as basic starting templates for projects.
In this post, I will show you how to control WS2812B, WS2811 or SK6812 individually addressable LEDs with an ESP2866 or ESP32 by using WLED. With the WLED firmware, the LED strip can also very easily be added to home assistant.
In this post, I will list and briefly describe the docker container I use on my home server. There are a bunch of very useful apps or services out there that you can simply run as a docker container on your home server. By self hosting you get total control over your services and data.
In this post, I will show you how to modify the UPS so it works properly. Years ago I bought these 18650 battery charge shield boards that can be essentially used as a UPS(uninterruptible power supply). I just recently made a project that required a UPS so I finally decided to use them. This is when I found out about all the problems associated with this module.
In this post, I will document the build process for my mini portable server made from an old Bitcoin miner case and an Orange Pi Zero Plus. One day I was looking through my SBCs parts bin and saw the Orange Pi Zero Plus board(still in its packaging) I had bought many years ago but never used. I got the idea to make a small portable server that could maybe run an MQTT broker, act as an AP, run a web server, etc.
