How to build a digital pinhole camera with a Raspberry Pi

Filed under

HowTos

At the tail end of 2015, the Raspberry Pi Foundation surprised the world by releasing the diminutive Raspberry Pi Zero. What's more, they gave it away for free on the cover of the MagPi magazine. I immediately rushed out and trawled around several newsagents until I found the last two copies in the area. I wasn't sure what I would use them for, but I knew their small size would allow me to do interesting projects that a full-sized Pi could not satisfy.

Configure an amateur radio gateway with a Raspberry Pi

Filed under
Linux
HowTos

The APRS (Automatic Packet Reporting System) is a worldwide digital communications network for amateur radio, providing a single national channel where people can monitor what is happening in the surrounding area.

APRS uses packet radio (AX.25), which Tom Karpiniec described in his excellent Opensource.com article "Packet radio lives on through open source software," as the transport layer.

The basic idea of APRS is to communicate information in the context of the location of an amateur radio operator, such as other stations' position information (whether mobile or fixed), repeater systems, weather information, or events. Amateur radio operators can, in addition, send direct messages to other amateurs via the network. As packets are sent, they include location information that can be displayed on a map. This provides an immediate view of activity in an area.

KDE Development Updates

  • Revisiting my talk at FOSSASIA summit, 2018
    Earlier this year, I had the chance to speak about one of KDE community’s cool projects that is helpding developers erase the line between desktop and mobile/tablet UI’s with ease. I’m referring to the Kirigami UI framework – a set of QtQuick components targetted at the mobile as well as desktop platforms. This is particularly important to KDE and a lot of projects are now migrating towards a Kirigami UI, particularly keeping in mind the ability to run the applications on the Plasma Mobile.
  • This Week in KDE, Part 2 : OYLG, Workspace KCM, Single/Double Click
    Last weekend, I went to İstanbul to attend Özgür Yazılım ve Linux Günleri (Free Software and Linux Days 2018) to represent LibreOffice. We had 3 presentations during the event about LibreOffice Development and The Open Document Format. We had booth setup with stickers, flyers, roll-up etc. These were all thanks to The Document Foundation’s supports! You can find detailed information about the event from here : https://wiki.documentfoundation.org/Events/2018/OYLG2018
  • Watching the Detectives
    For instance, Kevin Ottens has been writing about understanding the KDE community by the “green blobs” method, showing who is active when. Lays Rodrigues has written about using Gource to show Plasma growing up. Nate Graham describes the goings-on in the KDE community nearly every week. Those are, roughly: a metric-, a visual-, and a story-based approach to understanding the community, over different timescales. But understanding of a system doesn’t come from a single dimension, from a single axis of measurement. It comes from mixing up the different views to look the system as a whole.
  • Managing cooking recipes
    I like to cook. And sometimes store my recipes. Over the years I have tried KRecipes, kept my recipes in BasKet notes, in KJots notes, in more or less random word processor documents. I liked the free form entering recipes in various notes applications and word processor documents, but I lacked some kind of indexing them. What I wanted was free-ish text for writing recipes, and some thing that could help me find them by tags I give them. By Title. By how I organize them. And maybe by Ingredient if I don’t know how to get rid of the soon-to-be-bad in my refridgerator.

Phones: Purism, "Jolla Users", De-Googling Android Phones

  • Last Call for Librem 5 Dev Kit: order yours before June 1st 2018
    Purism has finalized the specifications for the Librem 5 development kit and will be placing all the component parts order and fabrication run the first week of June 2018. If you want to have early access to the hardware that will serve as the platform for the Librem 5 phone, you must place your dev kit order before June 1st, 2018. The price for the development kit is now $399, up from the early-bird pricing that was in effect during the campaign and until today. The dev kit is a small batch, “limited edition” product. After this batch, we are not planning for a second run (as the production of the phone itself will replace the dev kit in 2019).
  • Top 3 mobile phones
    When purchasing a new mobile phone, there are hundreds of models to choose from and, there are dozens of “excellent” or top-rated brands to consider. Therefore, it can be difficult to know what you are getting. Buying the phone upfront, on contract or buying a smartphone on finance are all options that need to be considered too. If you are ready to invest in a new smartphone consider these three models. Galaxy S9 Plus. This phone by Samsung is sleek, elegant, has a vibrant screen, resolution and excellent fingerprint scanner. The curved edges give it a distinct look and style. It is the Plus model, so has a huge touchscreen which is extremely intuitive. Quality speakers, outdoor body/casing and internal functionality make it a top-choice for a new smartphone.
  • De-Googling my phone, reloaded
    In this area the situation is now much happier than my first post indicated. As promised I used trainline.eu for booking some tickets (both for Deutsche Bahn and also on Thalys), and indeed this does a fine job. Same price, European rebate cards like BahnCard 50 are supported, and being able to book with a lot of European train services with just one provider is really neat. However, I’m missing a lot of DB navigator’s great features: realtime information and alternatives, seat selection, car position indicator, regional tariffs, or things like “Länderticket”. Fortunately it turns out that DB Navigator works just great with a trick: Disable the “Karte anzeigen” option in the menu, and it will immediately stop complaining about missing Play Services after each action. Also, logging in with your DB account never finishes, but after terminating and restarting the app you are logged in and everything works fine. That might be a “regular” bug or just a side effect without Play Services.
