Call for Subtitles

Deutsche Version weiter unten.

As you might know, during 32c3 the Subtitles Angels created real-time subtitles for all the talks which took place in Hall 1 and 2. These allowed hearing impaired visitors to follow the talks, and also provided assistance to the non-native German or English speakers.

As the last recordings are being released, the task of creating subtitles for all recording has started. For this we need your help!
If you have the capacity to create subtitles for a talk (perhaps one you wanted to watch in detail anyway), could translate a transcript or would like to do quality control, please check out and join #subtitles on hackint.

Being new to subtitling CCC talks is not a problem at all. Getting started is easy. And if transcribing is not for you, you can always work on the translations and quality control.

If you are willing to help, please take a minute to read through the new work-flow and style guide.
Please also read through these if you have previous experience subtitling CCC talks, because we have redesigned the entire interface to include Amara.

The finished subtitles will be released into the CDN and announced via Twitter at @c3srt_releases.

P.S. Remember the audio problems during the opening eventSubtitles were available all the way through. :-)
And by the way, subtitles also allow machine-indexing of the recordings. That means things like searchable archives become possible.

Wie Ihr vielleicht wisst, haben die Subtitles Angels alle Vorträge des 32c3, die in Saal 1 & 2 stattfanden, in Echtzeit untertitelt. Dies erlaubte Besuchern, die schlecht oder gar nicht hören können, trotzdem den Talks zu folgen. Zudem unterstützte dies auch Hacker, die nicht muttersprachlich Deutsch oder Englisch sprechen.

Während nun die letzten Aufzeichnungen des Congress veröffentlicht werden, hat die Untertitelung der aufgezeichneten Talks begonnen. Dafür brauchen wir Eure Hilfe!

Solltet Ihr Lust haben, ein Video zu untertiteln (vielleicht von einem Talk, den ihr sowieso schauen wolltet) oder Qualitätssicherung zu machen, indem Ihr den Talk anschaut und kleinere Fehler und Timings korrigiert, oder auch fertige Untertitel zu übersetzen: Schaut bitte bei oder in #subtitles (auf hackint) vorbei.

Solltet Ihr mit der Oberfläche von und dem Untertiteln von CCC-Vorträgen nicht vertraut sein, schaut Euch einfach den Workflow sowie die Untertitelstandards an. Fertige Untertitel werden im CDN veröffentlicht und via Twitter bei @c3srt_releases bekanntgegeben.

P.S. Erinnert Ihr Euch an die Audioprobleme während des Opening Events? Die Untertitel funktionierten den ganzen Talk hindurch. :-)
Übrigens: Untertitel machen ein maschinendurchsuchbares Vortragsarchiv möglich.


So, the STAR TREK DOOR has been a slow, “back-burner” project for a while. Recently, I got a little time, so I sat down and figured out how to hook up the air valves to a set of relays, and control those relays with an Arduino.

Here’s a video overview of the physical doors themselves and how we plan to open and close them with air valves.

This is a joint project, working on this with my brother-in-law, Fred. The doors are between his garage and workshop. Fred has been working on the doors themselves, the wall and framing, and mechanical connections. I’ve been working on figuring out the software, controls, and electronic magic that will drive everything.

STAR TREK DOOR ContinuesThe physical doors themselves are done, except for paint. Fred has also been making a pretty neat frame for the garage side. He cut alternating widths of wood and then glued them together for the nice light-colored wood on the inset of the planks that will frame out either side of the door. A similar piece will cross the top of the door.

I got all the main components – Arduino, breadboard, relay board, 12V power fuse panel, and air valves themselves all screwed to a piece of plywood. At this point, it’s not pretty, but it is functional.

STAR TREK DOOR ContinuesWe have a nice industrial door control with OPEN/CLOSE/STOP buttons on it. Those are momentary on buttons, but through the power of the Arduino, I can make them be whatever I want. I started with a Button Tutorial, and then modified it to suit my purposes, and added a Delay(1500) command after activating the air valve. That way, the valve will stay open long enough to fully open or close the door, even if the button is just pressed for a moment.

I programmed the pin for the STOP button to test out a sequence to open the door, pause (long enough for a person to walk though,) and then close the door. It seemed to work pretty well. If the timing is wrong for the real-world application, all I have to do is simply change the delay times. (It will also need a safety. We don’t want the door closing on a person!)

STAR TREK DOOR ContinuesAt this point, the basics of the control panel are working. The STOP button is just wired up as a “stand-in” for a single button we already have installed on the garage side of the door. It’s a capacitive touch button that lights up either blue or white with internal LEDs. It’s a neat looking button, but it’s only a SINGLE button. So, it needs to have functionality to both open AND close the door. I’d also like to explore using a variable in the Arduino that states whether or not the door is open, and then changes the functionality of that button based on whether the door is open or not. The air cylinders themselves also have built-in position sensors, which would be neat to use possibly as both a safety AND a “Is the door open or not?” sensor.

Here’s a video clip showing all the components actually working together. At this point, if the panel was simply mounted above the door, and air connected between the compressor and air cylinders, we would actually have functioning doors.

STAR TREK DOOR ContinuesI don’t like the look of how the air valves and tees are held together right now. I was able to find some not-too-expensive push connectors (similar to PEX Sharkbite style) for air, which might make it a little easier to connect all the air components and look cleaner. Once I really have everything finalized on what’s going on at the breadboard, I also need to decide if I want to pull the breadboard out and replace it with a custom circuit  board. One thing I DO need is a simple way to connect the tiny pin connectors to the larger wires going to the buttons AND provide strain relief. For the moment, I just used staples to nail the 18 ga lamp cord wire to the plywood and then made the electric connection with alligator clips. What would be the BEST/CLEANEST way to do this? Some sort of small screw down terminals?

I also have a rather large fuse panel mounted on the plywood. It was free, and I already had it. It supports many separate circuits, but for this project, a single DC fuse would probably be fine. I’m also using a bit of an overkill 12V power supply. I’ll want to replace that with a simple wall-wart. Lastly, the Arduino is running from USB power. I’ll need to solder up a 12V DC barrel connector so that it can run off the same power as everything else. I think we will make a switched electric outlet, and plug the wall-wart in to that. If the system is ever not working right, just switch off the power and manually open and close the door as needed.

I’ll definitely want to hang out with the guys at the Makerspace sometime soon talking Arduino, specifically how to integrate some more sensors and get feedback used to activate the doors fully automatically.

Science Hack Day Badges

We love rockets around here, so when it came to creating this years Science Hack Day badge, we decided a new design was in order. We created a new rocket shape design for science champions to wear . A video of the process is below. If you would like badges created for a community event do get in touch with us

Tickets are still available for the upcoming Science Hack Day Dublin on the 14th / 15th of November.

20 Jahre c-base auf dem Chaos Communication Camp

Die c-base feierte am 13. August 2015 den 20. Geburtstag direkt am Eröffnungstag.
Den Anfang machten e-punc, t. und macro mit einem 60 Minuten-Ritt durch die Geschichte der Station.

Danach wurde das c-booc offiziell vorgestellt. Ab 21:00 fand auf der BER-Bühne ein c-base Event statt. Archivmaterial wurde gezeigt und Crewmember beleuchteten einige Zeitabschnitte.

Danach folgte ein ausgewachsenes Set von Tasmo.

Dance, c-beam.

#Landesverrat von

Der Generalbundesanwalt Harald Range wurde gestern (4. 8. 2015) durch Justizminister Heiko Maas entlassen.

Das wäre eigentlich kein Thema für unser Logbuch, aber die Ereignisse die dazu geführt haben, gehen uns direkt an. Donnerstag letzter Woche twitterte die Netzpolitik-Redaktion, dass gegen Markus Beckedahl und André Meister sowie gegen Unbekannt (Quelle der Dokumente) wegen Landesverrat ermittelt wird. Markus ist Gründer und Chefredakteur des Blogs, André der Verfasser zweier Artikel vom Anfang dieses Jahres in denen es um den Ausbau der Internetüberwachung in Deutschland geht (zu den Artikeln 1 2). Grund waren zwei als vertraulich eingestufte Dokumente, die als Quellen mitveröffentlicht wurden. Was folgte, war kein Shitstorm und kein Rauschen im Blätterwald. Sämtliche Print- und Online-Medien sowie der öffentlich-rechtliche Rundfunk reagierten und nannten den Vorwurf des Landesverrates beim Namen: Einen Einschüchterungsversuch und damit einen Angriff auf die Pressefreiheit. Der Hashtag #Landesverrat wurde trending, ebenso  das Spendenkonto #DE62430609671149278400. Innerhalb von 36 Stunden wurde eine Demo organisiert, zu der über 2000 Menschen auf die Straße kamen. Range verlor die Rückendeckung der Regierung. Der Fall wurde zur Affäre.

Und was hat die Raumstation damit zu tun?

Die c-base schwebt nicht im luftleeren Raum (Noch nicht). Netzneutralität, Urheberrecht, digitale Überwachung, Datenschutz und Informationsfreiheit sind Themen, für die Nerds und Hacker schon immer etwas sensibler waren als die breite Masse der Gesellschaft. hat über diese Themen berichtet und uns informiert als es in den Redaktionen der Tages- und Wochenzeitungen noch kein Ressort „Digital“ oder  „Netzwelt“ gab. hat die re:publica mitgegründet, die wichtigste Konferenz die es zu diesen Themen neben dem Chaos Communication Congress heute gibt. hat die Digitale Gesellschaft mitgegründet um konkrete Lobbyarbeit zu leisten und diese Themenfelder nicht der Wirtschaft, Industrie und Content-Mafia zu überlassen. hat uns gegen BND, NSA, ACTA und für Freiheit statt Angst auf die Straße mobilisiert. hat uns politisiert.

Wir fordern eine umgehende Einstellung der Ermittlungen und eine Gesetzgebung, die es Whistleblowern ermöglicht, Informationen die uns alle angehen, straffrei ans Licht der Öffentlichkeit zu bringen.

Wir sind eine Raumstation – wir bieten Raum: Seit über 3 Jahren findet jeden ersten Dienstag in unserer mainhall der Netzpolitische Abend der Digitalen Gesellschaft statt. Hier wird zu all diesen Themen von kompetenten Menschen aus erster Hand referiert. Gestern hat Markus uns über den aktuellen Stand der Affäre #Landesverrat berichtet.

Danke an, macht weiter so!

Sunday Morning Project – A 3D Printed WebCam Mount for a Telescope

I recently acquired a new eyepiece to replace the damaged one that came with the Meade ETX-90 telescope I bought at a swap meet last year.  I decided it needed to have a web-cam mount so I designed and printed one that is a variation of a previous design for a microscope.  It took about 20 minutes to recreate the CAD file in DesignSpark Mechanical, and about 90 minutes to print on Son of MegaMax.

This thing has an odd shape to accommodate the odd shape of the camera.  I designed the adapter in two pieces so it could be printed without any support material.  After printing the two pieces were glued together with a little super glue.

Unassembled 3D printed WebCam adapter and eyepiece.

The adapter fits over the barrel of the 32mm fl eyepiece and stays put.


I shot a short video to test it and it works perfectly!  The cars driving by are about 1/2 mile away.


If we ever get a clear night I’ll try shooting Jupiter or Saturn and then run Registax to enhance the images.

Video Wall of Terror

This weekend, I helped decorate for a Halloween Party at my sister’s house. There’s an odd hallway that connects their main large public room to the rest of the house. It’s used for storage, and has shelves on both sides.

This year, I decided to decorate that area by creating a video wall effect. Something like a Television Control Room of Terror!

To start with, I simply filmed my brother-in-law with a video camera – only from WAY TOO CLOSE! I shot macro video of his eye and mouth. Then I edited the footage to create a custom looping DVD.

In the hallway, I set up multiple monitors. These are old monochrome standard definition monitors that were on their way to the recycling center. They were professional monitors, which means that they can pass a video signal through from one monitor to another, making it easy to daisy chain several monitors.

Next to the monitors, I set up three DVD players (including one car DVD player – hey I use what I got!) to play the three different custom DVDs – Right Eye, Left Eye, and Mouth. Each of the three videos is a different length, so they will continue to drift out of sync. That way, as they loop, the visuals are a continuingly changing experience through the whole evening.

Above the monitors, I set up a video camera on a tripod and fed it to some of the monitors. That way, when party-goers look at the monitor, they also see themselves. Having feedback on some of the monitors adds a sense of interactivity to the project.

After the monitors and DVD players were all set up, I covered the rest of the shelving with black paper. In a dark hallway, lit only be black lights, it’s a great effect of creepy images floating in the hall.

If you want more details on this project, I made a full step-by-step write-up on Instructables.
