Project:Bed frame

The goal was building a 2m wide bed frame quickly and without spending much on the wood, giving some extra budget for errors.

== Metal fittings ==
All four sides are connected to the bedposts using [https://www.knapp-verbinder.com/en/produkt/duo-system-frame-connectors/ Knapp DUO 62/15]. There is a great video (in German) on these connectors: "[https://www.youtube.com/watch?v=3tT5AFC3N6g Starke Verbinder für den Bau von Betten]". Once the distancing screw is tuned to the optimal gap, they don´t require any tools to assemble or disassemble the sides from the bed posts. While they are not the cheapest option, they are a great option for strong hidden connectors.

The mid beam is removable without tools as well, using [https://www.lignoshop.de/bettbeschlag-fuer-konstuktion-mit-mittelbalken-aushaengbar.html this fitting].

== Considerations ==

* The screws for the DUO on the bedpost are 40mm long, using a thin bedpost you need to place the perpendicular connector on the same post at a different height to prevent the screws hitting each other. This different height is required on the respective side piece as well.
* Resist the temptation to buy side pieces exactly 2m long. To get a clean edge, you need some extra that can be cut off.
* Don´t buy cheap pre-planed boards. Their cupping will make it hard to place the connectors properly (and look bad).
* Sand the end grain (for example on the top of the bed posts) to a fine grit size, this will prevent it to soak up too much coloring.

The letters "O P E N" should light up in green when the CoMakingSpace is open. To achieve this, the [[Project:SpaceAPI|SpaceAPI]] is polled regularly by an [[ESP8266]] and LEDs are turned on or off accordingly.

This project is using [[MicroPython]] for the firmware. The sign will connect to the [[Freifunk]] network on powerup and can be placed anywhere in the range of a Freifunk Rhein-Neckar network.

== Status ==

* ☑ Downloading and parsing the SpaceAPI.
* ☑ Doing it periodically.
* ☑ Switching an output accordingly.
* ☑ Build LED frontpanel.
* ☑ Solder LEDs.
* ☑ Find a power supply.
* ☐ Arrange cabling in a box.
* ☐ Attach it somewhere on the window.

Project:Face Shields

2020-03-28T10:28:17Z

Mitja: First draft

Shortly after the [https://www.bundesregierung.de/breg-de/themen/coronavirus/hackathon-der-bundesregierung-1733632 #WirvsVirus hackathon] the 3D printing community in Heidelberg started printing face shields and other urgently needed equipment at home. Our [[3D Printer Farm]] was temporary relocated to members' homes as well.
The whole effort is coordinated locally by Uniklinikum Heidelberg in collaboration with [http://medprint.org/ MedPrint.org].

We are also printing the [https://www.prusaprinters.org/prints/25857 Prusa Protective Face Shield].
Printed parts need to be sterilized before use, see the [https://help.prusa3d.com/en/article/prusa-face-shield-disinfection_125457 sterilization guide].

PlatformIO

2019-06-24T20:06:41Z

Mitja:

''PlatformIO is an open source ecosystem for IoT development'' [https://platformio.org/]

As this quote indicates, PlatformIO provides an ecosystem which supports the development of Internet of Things (IoT) applications based on various platforms and environments.

PlatformIO supports a broad range of [https://platformio.org/platforms platforms] and [https://platformio.org/boards boards] and integrates itself in [https://platformio.org/platformio-ide Visual Studio Code as well as in Atom]. For other Integrated Development Environments (IDEs), where no direct integration is available, there is the possibility to integrate PlatformIO using the [https://platformio.org/install/integration Command Line Interface (CLI)].

When working in the [[Arduino]] world, PlatformIO can be seen as an alternative to the Arduino IDE. However, PlatformIO is much more powerful (and in {{NL}}'s opinion also more user friendly) than the Arduino IDE. This comes both from PlatformIO itself as well as from the integration into the IDEs.

==Usage at the Space==
We are using PlatformIO within various IoT projects. We are trying to base any new IoT development on PlatformIO.

As example projects, please see the following:
* [[Project: Enhanced Door Bell]]
* [[Project: Flip Dot Display]]

==Main Advantages==
Compared to the Arduino IDE, PlatformIO provides several advantages, some of which are:
* Integration in your favorite IDE
* Syntax highlighting
* Autocompletion
* Git integration
* Library Manager
* Manually set build-flags per project

PlatformIO Seminar

2019-06-24T20:06:12Z

Mitja:

In February 2019, we hosted the first version of our [[PlatformIO]] Seminar.

In this seminar, the participants learn the basics of PlatformIO, the differences to the Arduino IDE and how to create and flash their first programs.

Please see the following details for hosting the seminar again:

==Description==
Microcontroller programming with PlatformIO
You´re interested in supporting your electronics projects with a microcontroller? Maybe you even started with some development using the Arduino IDE?
Unfortunately, development with the Arduino IDE can be quite tough, since it is missing some basic features. PlatformIO provides an alternative which enables you to develop for microcontrollers using a regular IDE such as Visual Studio Code.
This Seminar is for beginners to the world of microcontroller which want to write their first program as well as for users which are already used to the Arduino IDE and are now looking for alternatives. 
'''Please bring your Laptop.''' Ideally, you already have Visual Studio Code and PlatformIO installed already.

Microcontroller Programmierung mit PlatformIO
Du interessierst dich für die Programmierung von Microcontrollern? Vielleicht hast du auch schon die ersten Versuche mit der Arduino IDE gemacht?
Leider kann die Arbeit mit der Arduino IDE recht langwierig werden. PlatformIO bietet eine Alternative, die sich in viele Entwicklungsumgebungen wie zum Beispiel Visual Studio Code integrieren lässt.
Dieses Seminar richtet sich an Einsteiger in die Welt der Microcontroller, die hier ihr erstes Programm schreiben. Auch Fortgeschrittene mit Erfahrung mit der Arduino IDE aber ohne Erfahrung mit PlatformIO sind hier gut aufgehoben. 
'''Bitte bringe deinen Laptop mit.''' Idealerweise hast Du Visual Studio Code und PlatformIO bereits installiert.

==Timeframe==
In the first seminar, we needed approximately 2 hours, because everybody already had PlatformIO installed

Mitja:

You can learn 3D printing in our [[3D Printer Farm|3D printer farm]]! The term "3D printing" is actually quite vague and is used to describe various technologies which are defined by currently [https://techcrunch.com/2016/05/15/how-expiring-patents-are-ushering-in-the-next-generation-of-3d-printing/ expiring patents]. We will list some common ones below as we gather more experience.

If you are new to the subject, this [https://www.3dhubs.com/what-is-3d-printing introductory guide] by 3D Hubs is worth a read! An overview of the parts is given in this [https://www.youtube.com/watch?v=KZi3esvQ02w 3D printer anatomy] video.

You may also find our collection of [[3D Printing Ideas|3D printing ideas]] interesting. Did you know one of our printers can [[Multi-Material Printing|print several colors/materials at once]]?

There are two big German speaking communities: [http://3d-druck-community.de/ 3D-Druck-Community] and the [http://forums.reprap.org/index.php?236 German Reprap forum] (many English subforums available, too).

== Fused Filament Fabrication ==
All of our printers work by depositing molten plastic layer upon layer, a process which is called ''Fused Filament Fabrication'' (FFF) in the open source [http://reprap.org/ RepRap] community or ''Fused Deposition Modelling'' (FDM) in most commercial contexts. We support the idea of open source fabrication and therefore call it FFF in this wiki.

=== Limits of FFF ===
* '''no printing out of thin air'''
:support structures may have to be added where your model does not touch the buildplate and can be a real pain to remove...
* '''problems with overhangs > 45°'''
:printing ''into'' thin air does not work very well either. This limit can be stretched a bit by efficient cooling, though.
* '''nozzle size determines the maximum achievable resolution'''
:currently, all our printers are equipped with 0.4 mm nozzles.

I wanted to make a one-of-a-kind weddding cake stand and took inspiration from the "Lumberjack Championships", where [https://www.stihlusa.com/stihl-timbersports/watch-timbersports/springboard-chop-event-information-video/ one discipline] consists of chopping a wedge out of a tree trunk, jamming a spring board in there, jumping up on the board and cutting the next wedge until the contestant reaches the top to chop ''that'' off.

Luckily, I found just the right piece of ''Robinia'' on a forest hike and used it for this project after [[Project:Drying Timber|drying it for about half a year]].

== Approach ==
After the tree trunk had dried for about half a year, I cut slots into the bottom with [[Japanese Saws|Japanese saws]] and [[Bevel Edge Chisels|bevel edge chisels]] where the feet would go. These were just simple pieces of [[Scrap Wood|scrap]] plywood to increase the footprint and make sure the stand would not tip over.

Once the feet were [[Wood Screws|screwed]] in and adjusted to the size of the table the whole thing would be used on, I started cutting wedges out of the "tree" with the Japanese saws. Unlike after the chopping of the actual Lumberjack Championship, I ended up with a solid piece of wood after each cut that I numbered and used to hold the [[Baltic Birch Plywood|baltic birch plywood]] boards in place. ''An alternate (and perhaps easier) method here could have been the use of a chainsaw for a single straight cut of each board's thickness, but that was not the aesthetic I was aiming for.''

The plywood boards were also numbered and a screw hole was drilled through each wedge-board pair and into the matching place in the trunk. Although everything had held up well just by wedging thus far (tested up to approx. 7 kg), it would have been so bad if one of the boards would slip with a cake on it that the screws were added to be safe.

Finally, the boards were thoroughly sanded with an [[Eccentric Sander|eccentric sander]] and finished with [[Coconut Oil|coconut oil]] (and topped off with cakes after transport & assembly!)

''documentation unfinished, please just ask if you have urgent questions ;-) ''

I made a bunch of tealight holders out of birch trunks as a wedding decoration and will now work on turning this project into a woodworking [[seminar]] for beginners.

== Materials ==
=== Birch Logs ===
* from Bauhaus, very wet!
** better cut & dry in advance next time??
** risk of mold forming at the cut faces...

=== Tealights ===
* steel holders from <smile link>
* "eco" tealights without aluminum cases <smile link>

== Making ==
Need to test whether this can be sped up - drilling into the wet wood was very difficult! '''Lots''' of unforeseen mold problems..

* cut with [[Chop Saw|chop saw]] - log often too thick for the small Herkules saw...switch to [[bandsaw]] next time?
* sand cut faces with [[Eccentric Sander|eccentric sander]]
* let dry - continue & seal ends immediately next time?
* drill with <specific> [[Forstner Bit|Forstner bit]]
* let dry/seal again so the bottom of the hole is protected
* insert steel holder before the log shrinks too much!

In the [[Plenum/Meeting_minutes/2018-10-05#What_should_get_done_at_the_space_.28new_issues.29.3F | October 2018 Plenum]] we decided to create a Members Wall in the CoMakingSpace.

The Members Wall intends to provide an overview of our [[members]] with their names and special skills.

== Location ==
The Members Wall is located in the hallway. So when new people enter the Space, they can get to know the community which makes the CoMakingSpace awesome.

== Participate ==
Of course, we want all members to be reflected on our members wall. In order to include your own information to the Wall, please use the template available for download on [https://github.com/comakingspace/CommonFiles/tree/master/Printouts/MembersWall GitHub]:
* [https://github.com/comakingspace/CommonFiles/raw/master/Printouts/MembersWall/MembersWall.dotx Microsoft Word]
* [https://github.com/comakingspace/CommonFiles/raw/master/Printouts/MembersWall/MembersWall.odt Open Document format for everything else]

You do not have to include your picture. If you prefer not to put your picture into a public space, this is totally fine. In this case, feel free to include something else into the picture box or to remove it entirely.

For example, you could think about inserting a QR-Code which leads to your [[Special:MyPage|User Page]] or a picture of a project you are proud of!

'''Privacy Policy''' (sponsored by Captain Obvious):
The data you choose to publish will be publicly visible to anyone who is entering our building. Publishing it elsewhere, for example on the internet in form of a photo, requires permission by all affected individuals.

== Be Creative ==
You do not necessarily have to print your sign on a piece of paper. If you want to show off your craftmanship skills, feel free.

For example, you could [[Laser_Engraving_Photos|"print" it on wood]] with a [[Laser Cutter|laser cutter]]. You can also think about painting something yourself. Or whatever your creative mind tells you.

VisiCut provides user-friendly control of a [[Laser Cutter|laser cutter]]. It allows preparing jobs at home or keeping jobs for future runs.

== Materials ==
VisiCut can save settings for different materials and thicknesses and we will collect tried and tested values on a [[Laser Cutter Material Settings|material settings page]] once we have a cutter. You can then try successful settings from that page or import some when you install VisiCut (or at any time by clicking options -> download recommended settings).

== Laser Profiles ==
There are four standard profiles: cutting, marking, engraving and 3D engraving. Cutting and marking are vector ("line") based while engraving and 3D engraving will work with both vector and raster (pixel grid) files.

It's important to keep in mind these are fundamentally different, i.e. setting 100 % power/100 % speed in "mark" will produce different results than the same settings for "cut". You can make adjustments to these under options -> edit laser profiles.

You select the profile(s) you need through the "mapping" menu. Among the possible identifiers for groups of lines you want to treat as one are color and thickness - so you can choose to cut everything black and engrave everything else, for example.

=== Cutting ===
The laser moves relatively slow so there is enough heat along the toolpath to completely remove the material. Results in nice and clean cuts that should not need additional sanding when used with proper settings. When there are no vectors in your file, "cut everything" will trace the bounding rectangle.

=== Marking ===
Also called "vector engraving" - faster than cutting, which results in thin lines on your workpiece but ideally not too deep into cuttable materials.

=== Engraving ===
Turns colors in more or less dense point clouds using one of several available "dithering" algorithms and burns every point with equal power - the impression of color or even structure results from the spacing. Best zoom in on a detailed area in the preview (e.g. an eye in a photo) to have a better idea of how your work may turn out with the selected algorithm and resolution.

=== 3D Engraving ===
Engraves darker colors at a higher power setting than lighter ones, thereby creating a relief. It's easy to screw this up, e.g. two areas might look very different to the eye but actually have similar darkness when converted to grayscale. Nice for logos and similar artwork with clearly defined areas!

== Job Order ==
Sometimes a job has to be split into several parts and you might be confused as to which is which, and even if everything is saved as one job '''cutting may accidentally be carried out before engraving'''. Make sure to order the different steps in the desired way when mapping (the higher the earlier) to prevent such mishaps!

== Parametric SVG ==
Besides the standard [[Format:SVG|SVG]] file format, VisiCut introduces the so-called [[Format:Parametric SVG|"Parametric SVG"]] format which allows for changeable designs from within VisiCut. This may be useful, for instance, if you want to design a box which can be cut from various material thicknesses.

The file format adds some parameters to the SVG header which don't interfere with the actual file, thereby allowing it to be opened by other programs. For full documentation, visit the [https://github.com/t-oster/VisiCut/wiki/Parametric-SVG Visicut wiki] on github and look at the example files directly in VisiCut (File > Examples > predefined > parametric).

== Further Reading/Help ==
For detailed information, read the [http://hci.rwth-aachen.de/materials/publications/oster2011a.pdf Bachelor's thesis on VisiCut].

If you are having problems, check out our experience with [[VisiCut Troubleshooting|VisiCut troubleshooting]]!

The group behind VisiCut is also [https://github.com/t-oster/VisiCam/wiki developing "VisiCam"], a webcam-based user interface - please let us (and them!) know what you find out about using it. There should be at least one Bachelor's thesis about it as well...

USB Serial Converters

2019-02-02T15:59:57Z

Mitja: /* Windows */

Most [[microcontrollers]] use the serial protocol to communicate with other device and/or get flashed.

If you want to use a [[computer]] in order to communicate with a microcontroller, you will need a USB-Serial adapter. While these are often available on the board already (in case you use the development boards), you might have the need to use one of the specific USB-Serial Converters.

==PL2303==
{{ToolInfoBox
|tool name=PL2303 USB Serial Converter

|synonyms=
|type=PL2303
|material=
|used with=[[computer]], [[microcontroller]]
|location=[[E-Bench]]
|access=upon reading
|tutors=
|manual=
|donation=
|similar=
}}
The PL2303 is a cheap chip which is the base for many USB-Serial Converters. We have some available in the CoMakingSpace which you can use for temporary projects.

The ones we have are based on the PL-2303 XA/HXA chip. Unfortunately, the latest official drivers do not support Windows 10 anymore ([https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/prolific-usb-to-serial-comm-port-windows-10/0a4f8e48-7135-4434-9d10-349c9ce87fcf?auth=1 see here]).

However, somebody uploaded an old [http://wp.brodzinski.net/hardware/fake-pl2303-how-to-install/ driver version] to a wordpress blog, which makes the chips work on Windows 10. Of course, use this at your own risk.

 

==CH340==

==== Windows ====
The cheap USB serial module CH340 is not supported by default in older versions of Windows. Latest Windows should support CH340 out of the box.
Otherwise you need to install the [http://www.arduined.eu/ch340-windows-8-driver-download/ drivers] manually.

==== Mac ====
<pre>brew cask install homebrew/cask-drivers/wch-ch34x-usb-serial-driver</pre>

==== Linux ====
Works out of the box.

Event Planning

2019-02-01T17:11:37Z

Mitja:

Here we collect events that are either too far in the future, too complicated or too vague to plan right now. However, the basic ideas should not be lost and soon they just may become concrete enough to realize. Please add your ideas and let us know if you would like to help organize any of these!

== Organize an Event ==
Organizing an event can be quite some work. Therefore, any help you can provide to the [[managers]] will be appreciated. 
In order to support the scheduling and marketing of your event, please provide the following information to the [[managers]] (e.g. by sending an E-Mail to <code>info [ät] comaking.space</code>):
* In German and English if your event will be bilingual:
# Title of your event
# Description of your event (written like if you would talk to a person attending)
# Prerequisites (e.g. a Laptop)
* In either language
# Time needed
# Possible dates and times
# Image - e.g. a prototype you've already made, a screenshot or a kind of "flyer"

Once the [[managers]] agreed to your event and scheduled an appropriate timeslot, it needs to be advertised. For this, we have multiple possibilities:
* To be done by the managers
# Meetup
# Facebook
# CoMakingSpace [[calendar]]
# Eventbrite (if there are tickets)
# [https://www.rnz.de/kontakt/redaktionen.html Rhein-Neckar-Zeitung]]
# [[Newsletter]] (if there is time)
# Instagram
* Can be done by you
# [https://www.heidelberg.de/hd,Lde/HD/Erleben/veranstaltungskalender.html Heidelberg.de]
# [https://www.heise.de/make/kalender/new_event/ Make: calendar]
# [[Mailing List]]
# Post it into the WhatsApp Group.
# If you have enough time: Poster (has to be ordered latest 6 weeks before the event!)
# Create a wiki page collecting information and material ([[:Category:Seminars]])

== Recurring Events ==
* International 3D Printing Day (Dec 3rd each year)
* Arduino/Genuino Day (Apr 1st or 2nd each year)

== Miscellaneous ==
* Makers' BBQ
* movie night/LAN party for Long 3D Prints
* Make Heidelberg (suggested by Roman from Make Rhein-Main)
* [[Repair Cafes|RepairCafé]]
* [[Freifunk]] router flashing party
* hackathons
* Fundraiser Gigs (we should encourage local music makers that have original music to showcase their creations and help us raise funds at the same time)

== Seminar Ideas ==
If you have an idea for a cool seminar, there is a [[Seminar Ideas|separate page]] for that!
