Schritt-für-Schritt-Anleitung: Einrichten von Bluetooth auf dem Raspberry Pi

In diesem Beitrag möchte ich dir erläutern, wie man Bluetooth auf einem Raspberry Pi einrichtet und nach Geräte suchen kann. Ich verwende in diesem Beitrag den Raspberry Pi 3B+ welcher schon ein paar Jahre auf dem Markt erhältlich ist aber immer noch eine passable Leistung bietet.

Solltest du einen Pi 4 oder sogar einen 5er-Pi besitzen so kannst du trotzdem diese Anleitung verwenden denn diese ist auf diesen Systemen gleich.

Einrichten von Bluetooth auf dem Raspberry Pi

Der Raspberry Pi 3B+ hat WLAN und Bluetooth an Bord, d.h. du hast dieses Feature bereits dabei. Solltest du ein älteres Modell besitzen, so kannst du dir recht günstig einen Bluetooth-Dongle kaufen und so deinen Raspberry Pi nachrüsten. Software für die SSH-Verbindung zum Raspberry Pi Den Raspberry Pi kannst du über HDMI mit einem Monitor verbinden, jedoch bediene ich diesen lediglich von der Konsole aus und daher reicht mir eine einfache SSH Verbindung via MobaXTerm aus. Das Tool kannst du unter https://mobaxterm.mobatek.net/download.html kostenfrei in der Home Edition herunterladen.

Installieren von pi-bluetooth via apt Mit den nachfolgenden Befehlen aktualisierst du zunächst dein System, um danach das Paket "pi-bluetooth" zu installieren. sudo apt-get update sudo apt-get upgrade sudo apt-get install pi-bluetooth Ob der Bluetoothservice gestartet ist, lässt du dir mit dem nachfolgenden Befehl anzeigen. sudo systemctl status bluetooth Mit dem Befehl "hciconfig" kannst du dir deine Bluetoothadapter anzeigen lassen. pi@raspberrypi:~ $ hciconfig hci0: Type: Primary Bus: UART BD Address: B8:27:EB:AA:D5:1A ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING RX bytes:1604 acl:0 sco:0 events:102 errors:0 TX bytes:3572 acl:0 sco:0 commands:102 errors:0 Wenn dein Bluetoothadapter auf dem Raspberry Pi eingerichtet ist, können wir uns nun nach Bluetoothgeräte suchen.

Nach Bluetoothgeräten mit Python suchen

Im nächsten Schritt wollen wir zunächst nach Bluetoothgeräte in der Nähe suchen. Dazu installieren wir zunächst das Paket pybluez mit pip. pi@raspberrypi:~ $ pip install pybluez Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple Collecting pybluez Downloading https://www.piwheels.org/simple/pybluez/PyBluez-0.23-cp39-cp39-linux_armv7l.whl (128 kB) |████████████████████████████████| 128 kB 1.0 MB/s Installing collected packages: pybluez Successfully installed pybluez-0.23 Auf dem GitHub Repository von pybluez findest du einige Beispiele, wie du dieses Modul verwendest. Hier ist ein kleines Beispiel, wie du Bluetoothgeräte mit Python suchen und dir den Gerätenamen ausgeben lassen kannst. import bluetooth print("Suche Bluetoothgeräte") nearby_devices = bluetooth.discover_devices(lookup_names=True) print(f"Es wurde(n) {len(nearby_devices)} Gerät(e) gefunden!") if len(nearby_devices) > 0: for addr, name in nearby_devices: print(f"Gerätename: {name}") Auf der Konsole wird dann zunächst die Anzahl der gefundenen Geräte ausgegeben und danach die Gerätenamen. pi@raspberrypi:~/Python/BluetoothSearch $ python3 bluetoothSearch.py Suche Bluetoothgeräte Es wurde(n) 2 Gerät(e) gefunden! Gerätename: Galaxy A53 5G Gerätename: CSL-305080

Fazit & Ausblick

Nachdem wir jetzt Bluetoothgeräte via Python gefunden haben können wir als Nächstes eine kleine Schaltung am Arduino, ESP32 und Raspberry Pi Pico W aufbauen und diese Mikrocontroller mit dem Pi via Bluetooth verbinden. Dazu werde ich dir in den kommenden Tagen separate Beiträge veröffentlichen. Read the full article

Apptober Day 1

Now that I’ve got my Rasberry Pi Wall Display built and up on the wall, I figure Apptober is the perfect time to commit to finishing the software side of the project! This month I’m going to be hacking around with MagicMirror2 (a wonderful open source NodeJS app built for the RasberryPi) to make my little Wallberry the fairest wall display of them all.

Magic Mirror, On The Wall

The design aesthetic of MM2 is originally intended to turn a raspberryPi and a two-way mirror into a sleek, space-ship-worthy HUD. While I do love the minimalist mirror look, I’d prefer to give Wallberry a more classic, picture frame display look. Basically I want to go from the image on the left (Wallberry with a vanilla install of MM2) to something like the design to the right:

I’ve got a lot of tweaking ahead of me 😊

BTW - the image on the right there is from a company called Dakboard and they make GORGEOUS wall displays and I’d almost consider using their wall display software but alas I’m a fool for open source and MM2 has stolen my heart.

Project Requirements

Too many of my projects get abandoned unfinished due to feature creep so I’ve challenged myself to start REALLY small this time. To begin with I want my display to have the following features:

Current local time + date

Current time for at least two other cities in different timezones (I can’t do timezone math help me Wallberry)

Current local weather + temperature

Local weekly weather forecast

A gorgeous, high-resolution background photo that periodically changes

Exciting New Tech

I’m anticipating learning a ton of new stuff for this project, including:

NodeJS - finally, an excuse to learn Node 😄

SASS - cool cool, if I can’t avoid writing CSS forever then at least I can put variables in it

How to extend and theme MagicMirror - yay MM2 Modules!

The Unsplash photo API - because this seems like a really fun way to get great background photos

A ton of stuff that seems obvious but somehow isn’t when it comes to the UX design of wall display web apps

Some RaspberryPi-specific development things that’ll definitely pop up to bite me when I least expect it because nothing ever works in production like it does on your development machine

Tomorrow

Gonna get my dev environment all set up wish me luck 🙃

#MAGIC MIRROR RASPBERRY PI REDDIT HOW TO#

Plus, Docker is quite heavy and I'd like to have a lightweight deployment. "Just use Docker": Don't think this fully solves all the problems. Right now I'm dumping a Pickle in /var/lib/service/state.pkl, but I'm not sure if this is the best way? Persistence: I want the application to persist its internal state somewhere so that, if the server reboots, it can recover. A subreddit for discussing the Raspberry Pi ARM computer and all things related to it. I've read that some people use Bitwarden to store the secrets, or they commit them after encrypting them with GPG. Raspberry Pi - More than just magic mirrors and kodi r/raspberrypi. But I still have to ssh to the Raspberry the first time to write the file myself. For now, I'm following this guide: chmod 600 /etc/my_service and combine EnvironmentFile and DynamicUser in the systemd unit. deb for my app so that I can install it with dpkg. But I'm wondering if I should write a proper. Packaging: As I said, now my deploy script basically untars some files in a predefined location. Upgrades: I wrote a Fabric fabfile.py with 2 basic tasks, clean and deploy so I can ran them from another machine - the former deletes everything, the latter untars a git archive HEAD of the repository inside the Raspberry and extracts it to the right locations. Lifecycle: I wrote a systemd service unit so that the app starts automatically on boot. Some steps I've already started to streamline or automate: However, now I want to start applying better software engineering practices to this process. More or less, they all amount to $ ssh raspberry The Raspberry Pi smart mirror, also known as a magic mirror, is a futuristic digital mirror that displays everything from the current time and date to weather information, scheduled appointments, or the latest news headlines.The chances are that you have seen a Raspberry Pi smart mirror on YouTube or somewhere else on the internet.

Python 3 and PyGame in 2018

Table of Contents

1. Why PyGame?

2. Why Not?

3. Explicit Is Better Than Implicit

4. Three Pain Points

5. Other Cool Libraries

6. More To Come

1 Why PyGame?

PyGame is a nice library for getting started with game development. It is a good way to learn programming in a "real programming language" while making games1. There is very "magic" going on in PyGame, and you can go from print("Hello World") to drawing a triangle on the screen and then to Pong or Tetris with a smooth learning curve.

PyGame is also an easy way to get your feet wet in game development if you know and use Python already, for example in machine learning or web development. That's how I came to learn PyGame.

2 Why Not?

PyGame is just a low-level library for creating windows, drawing on the screen, reading joystick input, and playing sounds. OpenFL, Löve2D, FNA and LibGDX fill similar niches in the Haxe, Lua, .Net and Java ecosystems, respectively. If you want a full-featured engine, use Unity3D, UE4, or Godot. If you don't want to learn to code, you will probably fare better with GameMaker or Stencyl2. If you want to tell an interactive story with little actual gameplay, maybe Twine or Ren'Py are more your thing.

3 Explicit Is Better Than Implicit

Maybe PyGame is not for everybody… However, if you do just want to make small 2D games, and don't want to rely on automagic functionality, PyGame could for you. That means you have to code your own game loop3, poll the keyboard or game pad, and update the screen yourself.

Your game loop will look something like this:

import pygame pygame.init() # ... # setup stuff here screen=pygame.display.set_mode(screen_size) clock=pygame.clock.Clock() running=True while running: clock.tick(30) events = pygame.event.get() keys = pygame.key.get_pressed() for e in events: if e.type==pygame.QUIT: running=False elif e.type==pygame.KEYDOWN and #... # handle jumping etcetera # ... # move sprites around, collision detection, etc # ... # draw pygame.display.update() pygame.quit()

The ease of just drawing pixels on the screen and the lack of hidden features sometimes makes it harder to get started making certain games genres. If you start from scratch in Unity3D, you already have a level and a camera and you can just create a sphere GameObject and check a box to enable the physics engine. If you draw a circle on the screen in PyGame, it's just pixels on the screen. These pixels don't know anything about cameras, raycasting, or physics, so if you want to move the view around, make your circle clickable, or have it bounce off walls, you have to connect the systems yourself. PyGame gives you tools to check for collisions, a Sprite class that is the closest equivalent to GameObject, and a way to find out where on the window the mouse was clicked.

If you want to use a pre-made physics engine like Box2D, or roll your own, you have to write some glue code, but PyGame will stay out of your way.

This can even be a tremendous advantage when you want to make a game like Tetris4, or like SimCity, where you don't want to use 3D collision detection and a physics engine anyway, and collision detection happens on a grid. A game like Braid, where you can rewind the entire game state, will also be much easier if you have full control over your game loop. You can do all these things in a big and opinionated engine, as Hearthstone (a card game made in Unity3D) has showed us, but if don't need these features, you sometimes have to code around them. If you code around features you don't need, or re-build your own systems on top of a commercial engine, you might end up writing more code than if you had just started from scratch5.

All of this goes double for tools like PuzzleScript, RPG Maker, GameMaker, Bitsy or Twine. These are all geared towards certain kinds of games, and while they make it really easy to make that kind of game, they make you jump through hoops if you want to build anything else.

4 Three Pain Points

Although I just told you that PyGame is a great library, it is not as popular among game developers as it should be. This is mostly due to three problems dating back to the Python 3 days: multi-threading, deployment, and HD screen resolutions.

Multi-threading: Due to the GIL, an unfortunate implementation detail in CPython6, you can't have two threads execute Python code at the same time. That means your multi-threaded Python programs will still run in parallel, but there will only ever be one thread running at any time. On a single-core machine, there is not that much to worry about, because you only have one core that can run code anyway, but on a multi-core machine, you can't really take advantage of the additional cores. Still, what you could do is have one thread handle input and draw to the screen, while another, long-running thread does complicated enemy AI calculations that take longer than one frame to complete. That won't make your code run any faster in aggregate, but it will can at least ensure that the tick-input-update-draw cycle of the game loop runs at a smooth frame rate while the AI takes a lot of time.

If you're using i/o operations from the Python standard library, long-running numpy code or clock.tick(FPS) in PyGame, these libraries do the right thing and tell the Python interpreter that they are entering a section of native code during which Python code can safely run in another thread. But in general, you could have a Python function that calls native code that doesn't return for a while, so the Python interpreter is executing the same line of Python and other threads can't run. If that bit of native code is waiting for input, your whole program will freeze until the input arrives, even if you have ten other threads waiting that could do useful things in the mean time.

There are two modules to help you with concurrency in Python 3: multiprocessing and asyncio. The first has been around since Python 2.6, and lets you execute Python code in another process. This is useful if you have long-running computations like enemy AI that you want to run on another core. The other, asyncio is new in Python 3.37. With asyncio, you can run multiple coroutines in the same thread. A scheduling object called an event loop will execute coroutines piecemeal whenever there is input available. Because asynchronous coroutines are basically Python functions with some extra syntactic sugar, you can have tens of thousands of them running at the same time, unlike processes or kernel threads, which need a comparatively large amount of RAM to create and some time to context-switch. The use case for asyncio is pretty much the opposite of the use case of multiprocessing: Lots of threads8 waiting for i/o instead of long-lived processes that crunch numbers.

Deployment: There used to be no simple and easy way to package Python 2 games for end users. Sure, you could ask them to install python, either from Python.org or from the package manager of their choice, and give them the source code. Or you could use py2exe or py2app and create portable versions of a python script, but you couldn't build Windows, Mac and Linux executables from the same configuration file, and only on the respective platform. There were multiple competing standards for packaging python modules as source distributions: distutils, setuptools, distribute, and distutils2.

In the mean time, a smart person invented cxfreeze, which would automatically package every single dependency, every resource file and library used by your program, into one big archive. Unfortunately, that approach tended to pull in a bunch of DLLs that are already present on most end users machines. You also need to have the script already running on the target platform to analyse the dependencies at runtime.

With Python 3, setuptools has won, and the others have been merged into it9. There is a new file format for packaging Python modules called wheels10, that lets users install modules with native code without a C compiler. PyInstaller11 lets you build self-contained, portable versions of scripts on Windows, Mac or Linux based on the specification, and pynsist12 lets you create a windows installer for a Python script from any platform, because it downloads windows-compatible wheels and includes them without setting up a cross-compiling environment. The Panda3D project is even working on a cross-platform binary packaging system for Python 3 games based on setuptools!

HD screens: The software-based rendering in PyGame gets slower proportionally to the number of pixels. If you draw a 16x16 character sprite onto the screen, that makes 256 pixels. If you blit a background picture into a 640x480 (VGA) window, that's 307200 pixels already. If you scale that window up to 1280x960, that's four times as many pixels, and 1080p full-HD resolution has 6.75 times as many pixels as VGA. Things that were quite fast at low resolutions become a real bottleneck on HD screens, and you really feel the burn when you run PyGame on devices with a slower CPU and a HD screen, like a phone or a Raspberry PI.

Even if you run your game logic at a low resolution, and just scale up the screen to HD with pygame.transform.scale in the final step, that still means moving lots of pixels around in software. Scaling your game up to full-screen on a HD display can easily take the majority of your processing time. And remember, we effectively have only one core!

If you could copy your 320x240 surface into a texture and scale up your pixel art with the GPU, you eliminate a major bottleneck. The GPU is surprisingly fast and energy-efficient in phones, tablets and on the raspberryPI.

Fortunately, instead of directly drawing pixels into your window, PyGame can give you an OpenGL context and let you use whatever OpenGL bindings you like. In the past, that would have been with PyOpenGL, or pyglet. With Python 3, we can use ModernGL. ModernGL is much simpler than the other two. It targets only modern versions of OpenGL. Unlike PyOpenGL and pyglet, there is no support for immediate mode or the old fixed-function pipeline. You have to use vertex buffer objects and custom shaders. It's fast, and it lets you do fancy post-processing effects in addition to scaling.

If you need more performance, or fancier effects, you can incrementally transition from drawing into PyGame Surfaces towards creating individual textures for your Sprites and rendering directly with OpenGL.

5 Other Cool Libraries

The missing level editor: Tiled13 is a great level editor. You can use PyTMX14 to read the maps files, and pyscroll15 to render them.

Discord Rich Presence: All the cool kids are on Discord16. With pypresence17, you can let your player's friends know what the game is called, which level they are on, and how many points they have scored. It definitely beats having "now playing Python3.exe" as your Discord status line.

Creating Videos: moviePy18 gives you a simple API to create, load and edit GIFs, WEBM and other video file formats.

6 More To Come

The problems I used to have in PyGame haven't disappeared, but in 2018 and with Python 3.6, they have become solvable. It is possible to started making games with PyGame, and to polish and deploy them on Steam and itch.io. There used to be a tool to deploy PyGame to Android phones and tablets, but that was based on Python 2.7 and some hacks to get everything to run. With the current effort to port PyGame to SDL2, we can soon deploy games written in PyGame to Windows, Mac, Linux, Android and all major consoles, which support SDL219

This post is longer than I thought already, so I'll take a break here. In the coming days I will write more about using the asyncio module to do i/o in PyGame without tanking your frame rate, using the moderngl module to scale up your pixel art, and trying out deploy-NG, a setuptools extension from Panda3D to distribute games to end users.

Footnotes:

I recommend Al Sweigart's tutorials at http://inventwithpython.com/, and http://inventwithpython.com/pygame/

Maybe you want to start designing games first instead of learning to program, so you start out with these tools, but I would recommend you learn at least a little bit of a real programming language as well, to get some perspective. If you learn C#, which is a real programming language, together with Unity or Godot, please look up which features are part of C# and which are unique to your engine.

To avoid common pitfalls with game loops, read these: http://www.koonsolo.com/news/dewitters-gameloop/ and https://gafferongames.com/post/fix_your_timestep/

I am speaking from experience here. We made a Tetris-like game in Unity, and it was not worth the trouble. You can see the result here, but it's nothing special: https://blubberquark.itch.io/tetrominions

Please don't write an engine from scratch! People like Jon Blow, Tommy Refenes, John Carmack, David Pittman or Notch wrote their own 3D engines for various reasons. That said, if you actually need a big 3D game engine for your game, please don't write your own on top of PyGame. You are not John Carmack (unless you are, in which case you should stop reading this because you know more about programming than I do). Use Panda3D or Godot if you want something that is open source and Python-based (Godot Python support is still in beta, but getting there). Or use one of the commercial engines listed above.

I'm simplifying massively here. Look up the Global Intepreter Lock if you want to know more. The GIL also allows PyGame to call SDL functions without worrying too much about whether SDL is thread-safe. It's not all bad.

Only with Python 3.5 it has become really usable, though, and they are still working out the kinks in the API.

I mean that as in lightweight threads, Erlang threads, green threads.

You can still find distutils in Python 3 for backward compatibility reasons.

It manages to combine the good parts of Skype, Slack, and TeamSpeak, but it's not open source. https://discordapp.com/

https://github.com/qwertyquerty/pypresence

https://zulko.github.io/moviepy/

SDL2 already runs on the Nintendo Switch, for example. Unfortunately, the licensing terms of the Switch developer kit prohibit you from publicly sharing code that targets the Switch API in public. You have to contact Ryan Gordon and ask him for access, after signing the NDA. I am not a lawyer, this is not legal advice, but as far as I understand it, although the licensing terms of PyGame and SDL allow you to share the code, Nintendo could still sue you for breach of contract. That problem is not unique to PyGame though. A similar workaround exists in the Haxe world, where you have to contact Lars Doucet to get access to a version of OpenFL for Switch. There is also a homebrew version of Python available at https://github.com/nx-python/PyNX, but the NDA might prohibit you from using homebrew and reverse engineering.

The Apple and Mac application user community basked in the announcements from The National Association of Broadcasters 2007 Electronic Media Show (NAB2007). Participating in the NAB2007 show from a distance gives one an opportunity to forage the web for podcasts, webcasts, blogs, and news from the show. Final Cut Studio 2 will once again transform the industry with an impressive toolset including the new applications Final Cut Pro 6, Motion 3, Soundtrack Pro 2, Color, Cinema Tools 4, and Compressor 3, along with stalwart applications DVD Studio Pro 4 and LiveType 2.

The Final Cut Studio 2 suite introduces long requested features like surround sound, 3D support, and a post production HD codec, which Apple calls ProRes 422. Apple leveraged its intellectual property acquisitions like Shake and Logic to bolster it’s core Final Cut Studio 2 products. As Final Cut Pro burst the barriers to afford HD, Apple Color may just open the door to color grading for the rest of us. Previous systems working on 2K digital intermediates like Autodesk Lustre, IRIDAS SpeedGrade, and Silicon Color FinalTouch started at $24,995 and with control surfaces and hardware requirements easily topped $100,000 value, but Apple in its pursuit to make high end production tools affordable, decided to include Color, based on the FinalTouch acquisition, in the Final Cut Studio for no premium beyond the $1,299 asking price (upgrades begin at $499).

RaspberryPi Wall Display: Buildup

LONG post incoming!

It took me forever, BUT I FINISHED PUTTING WALLBERRY TOGETHER!

Aww, thanks Wallberry, you look nice too!

Putting Things Together

I’m not really experienced at anything hardware related so this part of the project was a particular challenge. Since I don’t have access to a lot of tools or a workshop space I tried as much as possible to use out-of-the-box solutions or hack stuff together from odds and ends around the house.

The easiest solution for the frame was to order a custom frame (I went with a simple wooden one from American Frame), which was surprisingly cheap since I didn’t need the acrylic glass or the mounting board:

American Frame didn’t have an option for cutting matboard as small as I needed (I only needed enough to cover up the screen’s ugly silver bezel where it peaked out from under the frame), so I thought “Michaels is having a 50% sale, why not get some matboard and cut it myself, how hard could that be?”

Oh my god what a pain in the ass, I DO NOT recommend doing this if you huge amount of area to cut out (I have 21x12 inches here) unless you have one of those big professional mat cutters with a backstop. Eventually I got something I could live with:

Aaaand this is the point where I realized that getting matboard with white backing would give me an ugly white boarder around my screen... ugh. But hey, that’s what Sharpies are made for, right? Right.

In retrospect, I should have ditched the matboard idea altogether, covered the half-inch of silver bezel with black electrical tape and called it a day. Live and learn, lol.

Cable Management Is The Worst

Now everything gets to go in the frame, and wow am I reminded that I hate cable management!

I put an extra layer of matboard against the back of the monitor screen as a buffer between it and the other components and used a bunch of (appropriately Halloween-themed!) electrical tape to fasten everything to the back of the screen and frame. Once I know for sure where I want everything to go I’ll find more permanent methods to secure everything, but the tape works great for now and makes it easy to change things if I realize something needs to move.

The raspberry pi is secured to another piece of matboard with plastic zip-ties, which at least makes it really easy to get it out again if I need access to it later.

Ideally I would have found much shorter cables and cut back on some of the mess, but in the spirit of using things around the house I just did my best to keep the ones I had from exploding all over the place.

Probably the most annoying thing is how much extra space is needed by the the monitor’s outward-pointing power and HDMI cable outlets. If you have extra time and money to spend on monitors I’d definitely suggest getting one with outlets oriented parallel to the screen.

I also should have gone with a much deeper frame, at least 2 or 2.5 inches instead of the 1.5 I thought I could get away with. For now I’ve solved the problem of needing some extra depth by sticking some styrofoam blocks on the back as spacers:

I’ll have to invent something classier later. At least there’s a ton of space for air flow and heat dissipation :)

All in all, it looks pretty awesome from the usual vantage point of standing at the whiteboard, so I’m happy with it.

Up Next: Software, Finally!

Wallberry is currently running a vanilla install of MagicMirror2 (which is what you see displayed in the photos above). I really love MM2 so far (super modable and has a GREAT community), but I’ll probably change the look and feel significantly from the intended mirror theme to something more like a traditional wall display. I’m really looking forward to this part!

Thanks for reading! If you’re interested in the post where I tear apart the monitor I used, check it out here.

Hack and Tell #41

This time during Hack-n-tell #41 we had 5 presenters

Melitonas continued his story about the smart home (prev. on HnT #38). He told us about the usage of Smart Assistant and how it could be used for automated opening of the gates or arming the alarm. He used RaspberryPi to run the compatible software. There are failsafe's in place to make sure the system remains operational even if the electricity cuts out. Overrides can be issued on demand as well, for example in case Melitonas needs to stop the gate in the middle of opening or closing.

youtube

Renardas gave an introduction to airsoft and what it involves. He made a multiple mode airsoft timer bomb to make scenarios more competitive. The 'bomb' can be diffused by entering a correct code on the keypad and will time-out depending on number of failed attempts. While there are plenty code and DIY schematics samples available online, he wanted to make one from scratch. This involved printing a PCB, where Renardas failed to account for ground correctly and had to fix it by soldering in some wires. The next step is adding a siren, and the outstanding piece is still in transit.

youtube

Anna gave a short presentation of screen replacement for an e-book. There wasn't much of a challenge, just some precision and diligence, really. Luckily, nothing else was faulty and the book is back to full operational.

youtube

Algardas shared his trials and tribulations of trying to install a pull-up bar in the corridor. One destroyed electric wire later, he had to repaint the entire wall. Eventually he succeeded and compiled a rather robust solution, that can be used to hang hammocks or a swing.

youtube

Ričardas presented his compact CNC 1419 project. Due to limited space, this was an optimal solution for him. It cost around 300 EUR and proved to be robust and reliable, the software runs steadily off an old Pentium PC with an SSD drive. The use has its own nuance, such as what materials the mill can handle, and what cutters can be used for each. Some bits and bobs were 3D printed as well.

youtube

Renardas took the prize this time and since he held it since the previous HnT, no pass forward was needed.
