Freie Fotos aus der Luft – wir haben eine Fotodrohne

Dieser Artikel ist Teil einer Serie, in der wir einige unserer neuen, wertvollen Anschaffungen vorstellen möchten, die wir dank einer Förderung durch die Deutsche Stiftung für Engagement und Ehrenamt umsetzen konnten.

Durch unsere enge Verbindung zu Wikimedia Deutschland und den vielen Projekten zu Freiem Wissen wie Wikipedia, Wikimedia Commons, Wikidata und so weiter haben wir schon immer sehr gerne zu Freiem Wissen beigetragen. So haben wir historische Bilder Ulmer Straßenbahnen aus der Bevölkerung gesammelt und mit der Scannerstation der Stuttgarter Community der Allgemeinheit unter Freier Lizenz verfügbar gemacht.

Was uns aber schon immer ein bisschen gefehlt hat, auch weil andere lokale Räume damit so wunderschöne Fotos machen, ist eine Drohne mit guter Kamera.

Durch die Förderung der DSEE konnten wir nun eine DJI Air 3 Drohne anschaffen. Und das eröffnet uns richtig viele Einsatzgebiete, z.B. tolle Luftbilder von historischen Gebäuden, Naturdenkmälern und anderen interessanten Objekten in der Region. Und das kommt danach natürlich alles zu Wikimedia Commons, zur freien Verfügung für alle. So können wir vielleicht bald auch Einreichungen für die Wettbewerbe Wiki loves Monuments oder Wiki loves Earth machen.

Nach ein paar Jahren des Übergangs gilt seit dem 01.01.2024 für alle Drohnenmodelle verpflichtend die aktuelle Verordnung der EU. Unsere Drohne liegt in der offenen Kategorie A1, UAS-Klasse C1, was bedeutet, dass man sie mit einem entsprechenden Führerschein in der Nähe von (aber nicht über) Menschen, sowie nahe an Gebäuden, fliegen darf. Für unseren Einsatzzweck daher sehr passend. Pro Akku haben wir auch eine Flugzeit von realistisch ca. 30-35 Minuten, was entspanntes Fliegen und Ausrichten für’s Foto erlaubt. Und wir haben gleich drei dieser Akkus gekauft. Als Betreiber der Drohne (nicht als Pilot!) tritt der temporärhaus e.V. auf, so dass die nötige Haftpflichtversicherung für unsere Mitglieder über den Verein abgedeckt ist.

Was machen wir also mit der Drohne bzw. was kannst du mit der Drohne mit uns machen? Wir werden regelmässig mit der Drohne auf Fototour gehen, und wenn du die Drohne fliegen darfst (A1 Führerschein), dann bist du herzlich eingeladen mitzukommen und mitzumachen. Wir planen aktuell die ersten Touren, z.B. sind die Bundesfestungen rund um Ulm ein guter Anlass für einen Anfang. Sobald es mehr spruchreifes gibt, wirst du es hier bzw. in unserem Kalender finden.

An dieser Stelle natürlich einen großes Danke an Wikimedia Deutschland sowie der Deutschen Stiftung für Engagement und Ehrenamt, die uns durch Ihre Förderungen solche Hardware und Projekte überhaupt erst ermöglichen.

Better stitching with PR1X – our new embroidery machine

This post is part of a series in which we want to present some of our new and valuable material that we were able to procure due to a grant by Deutsche Stiftung für Engagement und Ehrenamt.

Back in the old place, when we were thinking about how best to describe ourselves, we came up with this phrase: “A hacking and making space with embroidery, knitting and sewing machines […].” Knitting and sewing machines have kept kind of happening to us over time, so we have built up a veritable machine park. Only the combined sewing and embroidery machine purchased at the end of 2016 from the municipal start-up funds has no longer been available to us since our forced moving out from Ulm. So it was all the more obvious for us to buy a new one.

Embroidery machines are a very wild business. There are sewing machines with an embroidery module – like the one we bought at Weinhof – and there are very professional machines with 10 or more needles, which we felt were intended for the mass production of embroidered textiles. It turned out from our practical experience that neither end of that spectrum really suited our needs. We were never really satisfied with the combined sewing and embroidery machine from Weinhof, because although it sews great, the embroidery mode always felt a bit like a compromise. With the experience we have gained, however, we have now been able to say more precisely what we want: A machine that is easy to use, but is still first and foremost a real embroidery machine, so that we can embroider as many different things as possible with it.

One of the first steps with the new machine

In the end, we chose the Brother PR1X, and so far it has met our expectations very well and is being used pretty regularly. As with the previous Husky, there are some included borders and fonts that can be selected directly on the machine and then embroidered – but to be honest, some of these designs seem a bit out of place nowadays. Of course, you can also read files from a USB stick and then embroider them. As always, this requires special software from the manufacturer, which costs extra money. In addition, such proprietary software contradicts our principle of Free Knowledge and Free Software and the associated social freedoms: Everyone should be able to use this machine and control it from their computer.

Fortunately, there is a dedicated embroidery machine community that has developed the Inkscape plugin Ink/Stitch. This allows you to draw or import vector graphics with the free graphics software Inkscape and then convert them into machine code for the appropriate embroidery machine. This means that anyone can design their own patterns, logos, pictures or other ideas and then embroider them. Of course, we have already tried it out and spread our Zelti on all kinds of fabrics.

Also suitable for the holsters of devices we own: The logo indicates that this is from our collection.

At this point, a big hurrah to Free Software and everyone who contributed to this plugin. A big drawback with the old embroidery machine was that the free alternatives were not so easy to use back then, so designing the things to be embroidered was a big hurdle. With Inkscape and Ink/Stitch, we can now use even an impressive machine like the PR1X just like that.

Let’s go back to the hardware aspect: The fabrics you want to embroider are clamped into a frame, which is then attached to the machine. With the old sewing and embroidery machine, this frame was always built into the design of the classic sewing machine. This made it difficult or even impossible to embroider hoodies, for example. With the new machine, we now have nine embroidery hoops in different sizes and a machine that has been designed for embroidery from the outset. This means that pieces of fabric of any size can now be embroidered.

From small patches to baseball caps and sweaters, we have a suitable embroidery hoop for almost every textile.

Anyone who wants to use the new embroidery machine is welcome to come along to one of our sewing cafés or Maker Mondays and have fun with it after an introduction!

Print more – our new Bambu 3D Printer

This post is part of a series in which we want to present some of our new and valuable material that we were able to procure due to a grant by Deutsche Stiftung für Engagement und Ehrenamt.

Our Maker Mondays are one of the most popular offers in our space. 3D printers, laser cutters and woodworking tools are not things that everyone simply has at home, and we are delighted to be able to meet the needs of people from Neu-Ulm and the surrounding area with our tools and equipment. We were already able to purchase an Ultimaker 5 with a large build chamber and two print heads from the last DSEE grant – but this machine was intended as a supplement to the two existing Ultimakers procured by the city. Since we resumed operations after our move to Neu-Ulm, this single 3D printer has been a bottleneck: we constantly have a high demand for 3D prints, but with just one printer, visitors were backing up and we had to send many designs to the print queue until the next Maker Monday.

Example Benchies from the 3D printer: How does this benchmark print look like with the respective layer height?

To alleviate this situation, we ordered another 3D printer thanks to funding from DSEE. We thought long and hard about which printer we wanted to purchase. What’s important in a makerspace is the best ratio of maintenance costs to printing time and actual successful prints. If you only print for yourself at home and have no problem optimizing and adapting your own printer, you can rarely go wrong with the standard kits on the market (usually copies of a Prusa model). However, the necessary fine-tuning of the kit and usually also the replacement of safety-critical components – especially with some inexpensive kits that do not come from Prusa itself – are time-consuming and not always suited to a rather public setting like ours. It was therefore important to us to have a reliable and fast printer that is easy to use for as many users as possible so that we don’t have to put too much effort into ongoing maintenance and troubleshooting – and at the same time have a good 3D printing experience.

Time lapse: A 3D print using multiple colors

When we initially moved into the original premises at Weinhof, we were already considering many of these aspects. Back then, we opted for printers from the Ultimaker series, which met many of our criteria (including printing via ethernet) given the state of the art at the time. In the meantime, however, the market has developed considerably. In the current range of available models, our choice therefore quickly fell on the Bambu X1 Carbon.

In addition to an impressive printing speed (which also clearly outshines our Ultimaker 5) and a relatively large print area, this printer offers a very special treat: the Automatic Material System AMS. AMS offers the possibility of printing up to four different colors or even different materials within one print.

Automatically exchanges different filaments in different colors: The AMS

Furthermore, the printer offers automatic detection of printing errors and the option of creating time-lapse videos with the built-in camera.

The printer has already proven itself at our Maker Mondays and has significantly reduced the bottleneck in 3D printing. The hand wheel shown in the time-lapse, for example, has become part of the 3D-printed printing press that was in use at the Chaos Communication Congress. We are excited to see what our users will create with these new possibilities.

Bring order to Chaos - New shelves and boxes

This post is part of a series in which we want to present some of our new and valuable material that we were able to procure due to a grant by Deutsche Stiftung für Engagement und Ehrenamt.

Since our move to Neu-Ulm, we are still partly living out of the moving boxes in which our materials had been stored for almost a year. At Weinhof, we were able to use the many built-in cabinets from the Sparkasse era to store our material. We had already procured some heavy-duty shelving and storage boxes at the end of 2021, which made it much easier for us to re-start operations, especially in the workshop, since September. Thanks to the DSEE funding, we have now been able to purchase additional industrial shelving, open-fronted storage boxes and storage crates, which we are using to gradually clear out the remaining moving boxes and organize our diverse material in a more accessible and clearer way.

We can now also sort things out in the backstage area: Where are the DI boxes, where are the XLR adapters and where are the things that do terrible things to HDMI?

Whether power supplies with different voltages for hardware projects, parts assortments for workshops or the event-related material backstage, everything can now have a defined and labeled place so that it can be found quickly when needed and returned to the right place after use.

Additionally, we were able to procure an extensive stock of personal storage boxes. This means that every active member can have a box in which they can temporarily store their own materials. Be it to put away current projects when not working on them, personal items, a pack of tea or even the cozy slippers one might like to wear around the house.

Order for personal items and projects!

For the personal storage boxes, we opted for classic gray Euronorm containers measuring 40cm × 30cm × 22cm. This is a good compromise between enough space and not too much space. After all, the current 64 crates also need to be stored somewhere. Even on over 1000 square meters, space can get tight. And, let’s be honest, a big box quickly means a big mess.

Fluepdot seems happy, too

At the moment, each person is designing their own label, but maybe in the near future there will also be a common, chic, yet customizable label design. The main thing right now is that we are organized chaotically, as we have been from the beginning, but we organize our chaos wherever we can.

Das Verschwörhaus wurde über die Sommerferien zu sowas wie einem Ferienausflugsziel – alle möglichen Leute kamen in ihrem Urlaub vorbei, grillten mit uns, machten Ausflüge in der Gegend und haben cooles Zeug gemacht.

@leopardengruen, @robbi5 und @ubahnverleih sind beispielsweise letzte Woche mit der 360°-Kamera durchs Haus gezogen und haben unsere Räume vermessen und fotografiert. Und so lässt sich jetzt mit Rundumblick durchs Haus gehen und zumindest die Momentaufnahme vom 18. August 2017 erleben.

Ein Urlaubsbesuch lohnt sich trotzdem immer. Denn es sieht hier quasi zu jedem Zeitpunkt anders aus als die Woche zuvor 😉
