Home Automation, Raspberry Pi | 12 min | 131560
In the last years, I wrote several articles about Home Assistant (HA) and the possibility to replace the Zigbee hubs from different companies in your home using Zigbee2MQTT. Some of those articles are listed here (don't visit the links, they are outdated):

1 min | 20365#Raspberry Pi: Amazon Prime, Netflix, Disney, Spotify - a DRM official solution
Raspberry Pi | 1 min | 20365
Last June, I published an article about installing a DRM solution for the Raspberry Pi. If you don't know much about Widevine DRM, I'll quote my last article:
It is a rainy day and you have a Raspberry Pi, which is running Raspberry OS (Raspbian), and you think: I can make a media center to watch some movies/series. You configure everything, and then you see something like the next picture, every time that you want to watch Amazon Prime, Netflix, etc. using the Chromium Web Browser:

7 min | 150886#Raspberry Pi HQ Camera: Autofocus for the Telephoto Lens (JiJi)
M5Stack, Raspberry Pi | 7 min | 150886
This tutorial opens the series of articles about "Project JiJi" and describes how to add autofocus to the 16 mm Telephoto Lens mounted on the Raspberry Pi HQ Camera. In the past months, I've been working on a project to add autofocus to the lens and this is the result:
Adding some background to this: The Raspberry Pi Foundation offers different Raspberry Pi Camera modules since 2013. The first module (5-megapixel) was produced in 2013, and an 8-megapixel module upgrade (...

3 min | 6481#CrowPi2: a Raspberry Pi Notebook for Extended Creativity
Product Reviews, Raspberry Pi | 3 min | 6481
Last year, Elecrow sent me the CrowPi and I used it in some of my projects, including this video:
Together with the Corel USB accelerator, I programmed a YOLOv2 object detector, etc.
The CrowPi kit is magnificent and has everything you need to start playing with the Raspberry Pi. Furthermore, you get everything in a suitcase, that you can close and clean your "mess" in seconds. :)
Today, Elecrow is announcing a Kickstarter campaign to support the Crowpi2. This time, they integrated the Raspberry Pi in a notebook-like case (see fig. 1), and I think it i...

2 min | 7468#CC2531 & Raspberry Pi: Philips HUE bridge v1 replacement
Home Automation, Raspberry Pi | 2 min | 7468
As you may know, the Philips Hue Bridge v1 has support until April 30, 2020. This means, after April 30, 2020, no software updates will be made available and it will not connect to the online services. However, you can still control it locally via the "dedicated Philips Hue Bridge v1 app". Nevertheless, you have a device (connected to your network) that can be a "treasure" for hackers (MITM-Attacks), and the "dedicated Philips Hue Bridge v1 app" will disappear shortly! (...

4 min | 56123#Portainer: Managing Docker Engines remotely over TCP socket (TLS)
Analytics, Cloud Platforms | 4 min | 56123
This tutorial is about managing a Docker Engine remotely using Portainer connected to the protected Docker daemon socket (
TCP port 2376
). By default, you can manage Docker locally through a non-networked UNIX socket (option-v /var/run/docker.sock:/var/run/docker.sock
while running Portainer). But, if you want the Docker Engine to be reachable through the network in a safe manner, you need to enable TLS by specifying the--tlsverify
flag and pointing Docker’s--tlscacert
flag to a CA certificate. Then, the daemon only accepts connections from clients that are authenticated by a certificate si... - 14

4 min | 13354#Raspberry Pi: Encrypt (and save) Docker credentials
Raspberry Pi, Single-board Computers | 4 min | 13354
Usually, I login to different Docker registries (local, Docker Hub, etc.) with a computer running Ubuntu. I execute once
docker login
, then I enter the username and password, and after restarting the system, the access data is still available. That means, I write the credentials only once. But, on the Raspberry Pi, it was different until today: I needed to write the login credentials every time I booted the board.This article helps you to install the needed tools to save Docker login credentials on the Raspberry Pi, but not as plain text, so that the next time that you reboot the Raspberry t...

Product Reviews, Single-board Computers | 6 min | 36123
The Allwinner H2+, which integrates four ARM-Cortex A7 cores that can clock up to 1.2GHz, is powering the Orange Pi Zero LTS. The tiny board, which measures just 52 x 46 mm, features 802.11 b/g/n Wi-Fi, Ethernet, up to 512 MB of RAM, USB 2.0 Type-A and a microSD card slot. There is also a 26-pin unpopulated GPIO header along with a 13-pin header for a headphone, USB 2.0, TV-out, microphone and IR signals.
This board is the next generation of the Orange Pi Zero th...
