Thoughts on stuff that happens in our lifes and hobbies

Alive again, now with extra federation!

Mike. Check. 1, 2, 3... Check Czech Check. Is this on? I am deunaliving this blog! Again! And now I am trying to use the ActivityPub implementation of the Ghost blog. If you are not familiar with ActivityPub, think a "decentralized Twitter". If you know about ActivityPub but

I am alive!

Deploying a multiprotocol bridge with SkyConnect

Matter is becoming a reality! I still have a long way to go, but I wanted to give some pointers on how to achieve a Zigbee2MQTT + OpenThread Border Router with a Raspberry Pi and a SkyConnect. Note that you may want to follow the more guided/official approach: NabuCasa (the

An OpenThread Quest: My IPv6 Border Router

This is the first post on what I expect to be a long and successful list. Yes, let me dream, I know that it will be challenging. So, let's start with my agenda: I like open standards, and I have grown to hate ZigBee and WiFi protocols for

Simple dimmable light with ESPHome

In this entry, I will provide a general walkthrough on how to build a dimmable LED light, controlled with ESPHome and Home Assistant, and also including a physical control knob. This post will not be a comprehensive set of instructions on how to use ESPHome or how to build PCB.

Building a Portable SD Backup Solution

This is a project that is specially suited for photographers (both hobby and amateur ones). Even more if you are a travel enthusiast. This project intends to negate the disaster-scenario of losing all your photos --if your memory card corrupts, you lose it, or whatever else happens to your gear.
