Samba, RPi as Windows file/print server

-
Image
Updated 2024-01-05 OK with Bookworm ! If You want that the Raspberry Pi(RPi), shall appear in MS File Explorer or Mac Finder, as a File server, the easiest way is to install Samba. This also makes it much easier if You want to edit files on the RPi with editors from Your MS/Apple device. Or maybe moving files from/to the RPi.

SDR calibrate with kalibrate-rtl

-
Image
Updated 2023-12-05 !! OK, with Bookworm (32/64 bit) !! To optimize the reception with SDR:s, Software Defined Radios, it is important to receive on the proper frequency. Due to variations in production there could be deviations. The calibration could be done against standard GSM transmitters which are providing a stable reference frequency. Another way is found in the AIS-catcher application and use the information supplied in the graphs "Frequency Shift".

NMEA WiFi gateway

-
Image
Updated 2023-11-06 ! I have searched for a solution transmitting the NMEA data, from the navigation network, via WiFi, to for example  iSailor  or other Tablet/Phone applications. Most of these applications just accepts NMEA0183(N1) but many boats are also using SeaTalk 1(ST1) and NMEA2000(N2K). This post will cover, kept compact, my best findings covering both a DIY and a commercial approach to handle the different protocols.

Raspberry headless install with WiFi

-
Image
Updated 2023-10-17 ! To make a headless, without monitor, keyboard and mouse, install of Raspberry Pi OS on a Raspberry Pi(RPi) with built in WiFi and no LAN cable connection, please follow the instructions below. For example the RPi Zero and Raspberry Pi 3 Model A+ don't have any LAN cable port so the setup is quite usable. To make an active WiFi connection at first boot You have to use the "Advanced options" in Raspberry Pi Imager or create, old way, a configuration file called " wpa_supplicant.conf ".

TP-Link Deco M9 V2 Plus software update

-
Image
Updated 2023-10-04 ! TP-link Deco M9(M9) is a nice Mesh solution but it could be that the software/firmware is dated 2019. This is an old one and you really shall update ! Probably you can't update via the TP-link Deco app and therefore you have to make some extra measures updating via a Mac/Windows program. In a former post I gave some hints and links if you are using an ethernet backhaul, using access point mode, and please check below how to set up without a router and manage more than one network. Post with Teltonika 4G router as receiver / bridge for the mesh network.

Updated 2023-07-12 ! There are some Node-Red nodes, (NRN), that are dependent on the old Noble package which don't work on Node > v8.  One nice and simple NRN is the  node-red-contrib-noble  which have the same problem. I picked up the freshest source, dependent on  @abandonware/noble , forked it and added install instructions. It works with Node <= v18.

Teltonika router as security, burglar, alarm !

-
Image
The use case was that we on our yacht have a security alarm which is using 2 G, service terminating during 2024 ?, so it was time to check for some other solution.  Since several years we have used the very nice  Teltonika RUT 240 (TR) onboard which have served us very well. Knowing that this device have both a digital in and out I started to check if it could do the job ??  Googling didn't give any direct clues but the " Input/Output " handling together with " Profiles " changed with a SMS, " Mobile Utilities ", is doing the job. Please note that this setup could be done with any of the routers from Teltonika with I/O !!

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.

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... 😉

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)  ?

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

-
Image
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. 😉

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.
