AIS receiver and dispatcher ! The best ?!

-
Image
Updated 2026-05-11 I found this amazing application,   AIS-catcher , just scrolling around on Youtube and  it includes "all" you need for an AIS receiver staying ashore or installed on a boat. It is compatible with a wide range of Software Defined Radios (SDRs). These include RTL-SDR dongles (such as the ShipXplorer AIS dongle and RTL SDR Blog v4), AirSpy (Mini/R2/HF+), HackRF, SDRPlay, SoapySDR, and file/network input (ZMQ/RTL-TCP/SpyServer).

Signal K quick install, Raspberry Pi, Ubuntu

-
Image
Updated 2026-05-03 ! I have got some questions installing, just,  Signal K (SK) so will do a summary with links. Signal K is the hub to receive data, from different devices in different data formats, and send it on to different equipment, or databases, in different formats. Most common for standard marine equipment are the old NMEA 0183 and the newer NMEA 2000 protocol which is also handled.  Besides the SK "hub" function developers  have  created  plugins  for different purposes. This is due to that  SK is open-source ! Sharing is caring ! In this post you can check the devices I'm using connected to the SK server and also my setup.

DYI Weather template with data from Davis Weatherlink using Claude

I have been very fond of our weather website with the  Weather34 application (W34),  but there is an end to everything..... Doing an upgrade of the server it collapsed and showed a blank screen. I'm no programmer but I had to test if it was possible to update the app using ChatGPT and Gemini. Burt several hours later I gave up !!

Updated 2023-10-13 ! There is a "new kid in the block" called NetworkManager (NM),  configuration of network interfaces,  which in OS "Bookworm", Debian 12, is replacing  the former used  dhcpcd . NM isn't really new since the first public release was made 2004. In this post I will write down some NM hints for an easy start since I didn't find any myself.

Underfloor heating with PID controller, Node-RED

-

Updated 2026-01-03 ! In a former post I did some hacking/checking how our underfloor heating control system handled the valves, via actuators, regulating the heat.  Now it was time to do some tests with Node-RED(NR), with a PID controller ,  and a Shelly 1 (S1) connected via WiFi and driving the actuator. I really nice solution with Home Assistant and a relay board is found here !

Home Assistant with VirtualBox or Proxmox or Linux KVM ???

-
Image
Updated 2026-02-24 ! After testing Home Assistant (HA) for a while, I’ve realised it could improve my home automation, despite that I'm using Apple HomeKit. When I tested HA with Node-RED and some other "Add-ons", on a Raspberry Pi 3 (RPi), I found that its resources wasn’t enough. The following setup could be any computer but I recently bought an Apple Mac Mini M4, replacing my 2018 (M18) model, so the M18 was really a great candidate for my HA setup. The preferred method running HA is through the  HA Operating System (HAOS), which makes your "life" easier. 😉

Raspberry Pi OS Lite with GUI, RDP, VNC, Chromium

-
Image
Updated 2025-10-02 ! I like the Raspberry Pi(RPi), with Raspberry Pi OS Lite (no Desktop is included), headless operation, and then adding the software You need. Until now I haven't had a use case where I needed a Desktop but now was time.  Why don't use the Raspberry Pi OS with Desktop ?? In that package there is a lot of software I don't need and I really want to optimize the RPi. I think that the less software You install the happier RPi will be... 😉

iCloud drive sync, or mount, with a Linux, Ubuntu, device

-
Image
Updated 2025-01-23 ! With my project to keep a MacBook Air 2011(MBA) alive , Ubuntu installed, i searched for a solution where my iCloud drive(iCD) was  continuous synced with my MBA. This must work both ways so even a file change made on MBA should be replicated to iCD. rclone now, 2025-01, works with iCloud !! Setup below !! Before "rclone" was working with iCloud I solved my sync between iCD and MBA with Syncthing (ST). Check below. ST doesn't sync with iCloud so the work around here was to use my MacMini, Mac OS, as the "Middle man". It's always on and synced with iCD.

Homebridge made simple, HOOBS

-

Updated 2021-08-08 ! I have written several post about the HomeKit Bridge, Homebridge (HB), but if You want another simple way, with GUI, to handle the server and plugins the guys at HOOBS  have done a nice software package. I personally prefer the Homebridge  "native" install , which seems to be updated more frequently.

Installing Ubuntu 24.04 or 24.10/25.04 on an old MacBook Air(2011)

Updated 2025-05-20 ! I have done several posts Blogging about how to keep an old MacBook Air(MBA), mid 2011(A1369), with SSD disk "alive". I have used the fantastic software package OpenCore Legacy patcher to upgrade the Mac to the latest Mac OS.  A while ago i tested Mac OS  Sequoia (15.3), on the mentioned Mac, but I had to admit that it was to much for the 14 year old companion. I really like the Mac and everything works, after a battery change , so it ended up with installing  Ubuntu 24.04.2 LTS  or if you want the latest scroll down and get Ubuntu 24.10/25.04. Ubuntu on  Mac Mini (2018) and MacBookAir (2010)  ?

Clone the Raspberry boot disk

-
Image
Updated 2024-02-20 ! A very nice way to fix a backup is to make a copy, bootable, of the actual SD card You are using on the Raspberry Pi(RPi). This will be done even when the RPi is up and running ! This application can also be used to make a bootable SSD or USB drive !! You clone from the command line so You don't need the standard GUI, Pixel, and the " SD card copier "  function. It is also possible to set up a a scheduled job, cronjob explained later, which for example makes a clone every night at 1 o'clock.
