    Your question reminded my immediately about one of my favorite 35c3 talks Butterbrotdosen-Smartphone - Mein DIY-Smartphone-Bau from 2018-12-29. It is in German language, but has an English translation, too. Maybe it can give you some good starting ideas?

    Video: 1080p

    Story, Translated with DeepL.com (free version)

    I would like to show you how I built a smartphone from a Raspberry PI. The problems and difficulties I encountered and the solutions I found. The project is not yet finished, there are still a few small things missing. Nevertheless, I want to show you my smartphone in the practical sandwich box and tell you how it came about.

    I had no idea that building a smartphone could be so complicated. Raspberry Pi + touch display is not all there is to think about in this project. At the moment, the smartphone project lives in a sandwich box and attracts attention on the subway. If the power bank can passthrough, that’s an advantage, I’ve found. Setting up the X and Y axes on the touch display so that you can also use the on-screen keyboard was not so easy. And I had to realize that Landscape is not the right size to work smoothly. Most Linux programs are not directly touch-compatible or require too much memory. Then there were also big challenges! Learning to solder was one of them. First learning how to solder, then learning how to desolder, and then daring to use the PI. I would like to tell you these and other stories about building my smartphone.


  • Genaus so ein “Puzzle” hatte ich damals vor mir liegen, aber dank der Photos und ein bisschen Ausprobieren fanden alle Teile (auch gehüpfte Federn) wieder ihren korrekten Platz.

    Bei mir hat die Bohrer-Methode immer gut mit meinen normalen Metallbohrern funktioniert. Es gibt anscheinend aber auch spezielle "Schraubenausdreh"bohrer, die u.a. sich beim Auf-/Linksdrehen nicht aus der Schraube drehen.

    Mein Vater würde übrigens einfach eine Schraube auf die Schaube schweißen (wenn die Schraube geeignet ist) und dann mit Zange oder Schraubendreher herausdrehen. Damit habe ich aber nur Erfahrung als Zuschauer 😆


  • Hope I have interpreted the photo correctly and this is just a metal screw, that has become to round to be screwed out with a hex wrench.

    In such case, I use a drilling machine to carefully drill a small metal-suited drill a few millimeters into the screw. Then I remove the drilling machine and hold the drill (still in the screw) with combination pliers (or similar pliers) and unscrew the metal screw (again carefully).

    I hope my translation of the tool names are close enough to understand what I mean :)

    In German it would be: Einen Metallbohrer mit Bohrmaschine einige mm in die Schraube bohren, dann mit Kombizange den Bohrer festhalten und zusammen mir Schraube herausdrehen.

    EDIT: also please be careful when opening up the keyboard and document your steps with photos. When I repaired a 80s Korg some years ago, there where many parts that could spring out of place, e.g. when lifting the keys.




  • Definitely dislike MS, generations of my workstations have small, yellow “Microsoft Free Workstation” stickers on their monitors, but VSCodium (in my case) is not really bad.

    Also I really like the Xbox360 console and (as a hacker and maker) still love the first Kinnect. The Kinnect is an excellent piece of sensor-hardware, was rather cheap when purchased in used condition and it works very well with Linux.

    MetaGer is a German meta search engine (utilizing several search engines in the back). UI and results are of course available in many languages.

    https://metager.org | https://metager.de

    From their About page:

    What makes MetaGer special?

    MetaGer is different from other search engines. This is reflected not only in our public good orientation and focus on privacy, but also through some unique features:

    • Possibility of creating a personal blacklist
    • Function of the search in the search
    • Advertising-free search possible
    • Integration of search engine projects like YaCy
    • The only German search engine that combines results from several large web indexes
    • And much more…

    What We Stand For

    Guaranteed Privacy

    Data protection and privacy are important to us. That’s why we don’t track or store personal data and offer several services to protect your privacy, for example our anonymizing proxy (“Open Anonymously” feature).

    Non-Profit Association

    MetaGer is a project of the non-profit association SUMA-EV, Association for Free Access to Knowledge. SUMA-EV is primarily committed to promoting media literacy.

    Diverse and Free

    MetaGer produces diverse results because it is a metasearch engine. We have explained exactly what this means in our transparency statement. By publishing our source code, we show that free access to knowledge is important to us. Our source code is free and open source.

    100% Renewable Energy

    Sustainability and resource consumption is also a big issue for us. Therefore we pay attention to the energy consumption of our services and only use electricity from renewable energy sources.


  • If you are unhappy with suggested XSane, but only want an OSS solution, I do not know a good alternative.

    Possible non-OSS solution

    Although I am an open source enthusiast, there are few application where I use commercial, even non-OSS solutions on Linux. One of this exceptions is for scanning.

    Background: I “administrate” some legacy Epson scanners used with my family’s Linux boxes and got them all to run with a software called VueScan, with the following restrictions:

    • Perfection 3490 worked out of the box, no drivers required
    • Perfection 3170 requires Epson drivers (iscan_2.10.0-2_i386.deb, iscan-plugin-gt-9400_1.0.0-2_i386.deb), but only runs on 32bit Linux
    • Perfection V30 requires Epson drivers (scan-gt-f720-bundle-2.30.4.x64.deb.tar.gz) and simply works on 64bit Debian

    As you see, it might be a bit of luck, if a device works out of the box or not.

    Unfortunately your Epson Stylus SX435W seems not to be listed under the supported Epson devices (click red button “All drivers” to see all supported Epson scanners).

    If you happen to find no solution, I suggest to use the trial version of VueScan and check if your Epson simply runs or not.

    EDIT: sorry, I forgot to mention. that the VueScan GUI has plenty of those processing options you are searching for.








  • For information see Wikipedia.

    Setenil de las Bodegas is a town (pueblo) and municipality in the province of Cádiz, Spain, famous for its dwellings built into rock overhangs above the Río Guadalporcún. According to the 2005 census, the city has a population of 3,016 inhabitants.

    […] The town extends along the course of the Rio Trejo with some houses being built into the rock walls of the gorge itself, created by enlarging natural caves or overhangs and adding an external wall.

    also nice:

    Setenil has a reputation for its meat products, particularly chorizo sausage and cerdo (pork) from pigs bred in the surrounding hills. As well as meat, it has a reputation for producing fine pasteles (pastries), and its bars and restaurants are among the best in the region. Its outlying farms also provide Ronda and other local towns with much of their fruit and vegetables.


  • Let the religious shell wars begin … again

    Only right answer is of course TCSH. Not much documentation and support, ancient but still receives new bugs in 2021 (on Debian), but attackers hate it! (I love it)

    My real suggestion is to learn zsh and fish (and bash). Try using them for all your purposes and in the end you will automatically find the one (or more of them) that suits you best and that you like most for your daily tasks.
