Empty the water system

Empty the fresh water system with compressed air !!

One of the things, when You head back to land with the boat, is to empty the fresh water system. I have got several instructions/tips over the years but the best advise I got is to empty the pipework with compressed air.

Some time ago I bought a handy Stanely compressor. Just below 10 Kg in weight including a 6 liter tank. Nice for smaller works


So how do You connect the compressor to the pipe works ?
On our boat the pipework is made with Whale System 15 so I built an adaptor with;
  • 1 meter Whale 15 tube
  • Standard connector with 3/8"
  • 3/8" adaptor from the Whale 15 system
So now it is very simple to just disconnect the pump from the system and instead connect, via the adaptor, the compressor to the pipe works.

Then start the compressor and go around in the boat and open the taps one by one so all the water goes away.

NetworkManager UI and access point, hotspot

-

Updated 2023-10-12 ! In a former post I shared some thoughts about how to start using NetworkManager (NM), on a Raspberry, and here I will continue with additional examples that can help with network setup. NMTUI is NetworkManager text UI which can handle the most common tasks in a easy way. An access point or hotspot will be configured. " sudo nmcli connection edit xxxx " is a command that guides you throw a change of parameters.

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

Updated 2024-07-01 ! 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

-

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.

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.

Signal K quick install, Raspberry Pi, Ubuntu

-
Image
Updated 2025-06-23 ! 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.

Clone the Raspberry boot disk

-

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.

SeaTalk1 to NMEA 0183 converter, DIY

-
Image
Updated 2024-08-30 !  !! Another SW solution is available for RPi 5 here !  using the same HW. Thanks to Thomas, (the guy with the nice marine interface board ) ,  it's now possible  to decode, one way, the SeaTalk1(ST1) sentences in a pretty simple way. You just  use OpenPlotter(OP) and/or SignalK(SK) and an  Optocoupler . The thing that made it, is that Thomas   has released a "how to" and  Python source code , that will read the data from a GPIO pin on the Raspberry Pi, (RPi), and format it so the standard parser in SignalK can translate it to SignalK delta format. It is then  available as NMEA 0183. It's even possible to send the data in to a NMEA 2000 network, with a proper hardware interface.

Volvo Penta NMEA 2000 Gateway

Updated 2021-06-15 It's always nice to have ALL information at the same place, navigator/plotter, when You are out with the boat.  What could be missing is the engine information/data. If You have a Volvo Penta from 2006 or later it could be pretty easy. There are some "standard" NMEA 2000 gateways to choose from, for example;  Volvo Penta has it's own 22813366, 3889758 Raymarine ECI-100 Maretron J2K100 .....

Waveshare CAN hat with Signal K & OpenPlotter

-

Updated 2024-07-08 To get information from the NMEA 2000(N2K) network, to the RPi, I have been using  Actisense NGT-1 , for a long time,  and later also the  Yacht Devices YDWG 02  but now it was time for a Raspberry Pi(RPi) CAN hat(CH) from Waveshare(WS). WS have 3 different models but I picked the 2 channel isolated one . It's recommended to use an isolated one which also is demanded for those interfaces which can be approved by the N2K group.

AIS receiver and dispatcher ! The best ?!

-

Updated 2024-10-25 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).
