@davedarko who did you use to make your penguin PCBs? i'm thinking of trying AISLER because they produce in Germany and support LibrePCB.

https://blog.aisler.net/your-librepcb-project-as-a-powerful-prototype-fe3d4c621316

Old pre-cloud EAGLE and dirtypcbs / oshpark. Green penguins don't look so nice ;) someone ordered them at jlcpcb with parts from lcsc in one packet. Never used LibrePCB, wasn't motivated for KiCad because of time constraints.

My tip for aisler: be a bit more generous with the specs than the design rules suggest and really check the rendering before hand.

Well, their specs kinda are the "absolute maximum ratings"
I just ordered a board from them - just out of interest, do 0.25mm width tracks turn out fine?

@Xasin  10 mil (?) should be totally fine. the longer your wires on the pcb get, the harder it gets for every pcb house to get good results. It was a bit fuzzy to me if the design rules are specs that you definitely can achieve under all circumstances vs. stuff that you can pull off for a percentage of boards. 

Where are you located? I am at the Belgian embassy, cannot find you around...

we're almost neighbours btw. near Halleninspektor of Hall 2

anyone here yet? haven't spotted the jolly wrencher

yes!

coming coming!! what should I bring? ;)

Yourself, a computer, and whatever else you need to be happy!  We've got more than a few FPGA-interested folks here.  Demos?  

Hi everyone and thank you very much for adding me! 

I'm not finally sure what to carry to 35C3, but most likely some modules of a custom made flip dot display, which I'm working on together with twam, who will also apply for your fine assembly. The flip dot display might be considered as write only memory ;-) But wait, there were people measuring voltage/current to determine if the dot actually turned. So it could be read by trying to change it. But thats not our approach. We are working on modules, which cover 1/16 of a full circle, and can be chained by RS485 and be aligned to form a full circle (diameter approx. 1m). The project uses 3D printing, lasercutting, custom made pcbs and a STM CPU per module (16*14 dots). Largest assembled unit is afaik a 3/16 Circle.

I'm looking forward to see you all and about 15.000 more awesome people in Leipzig.

Kind regards

Jo

Woot!  More flipdots.  

I've got a cheesy 14-dot display that I used as a countdown timer for the unconference last year, and I've got a few more 7-seg lines sitting in my closet, shaming me. 

My plan is to simply put the rest into a line -- 1.X m long because doing anything in more dimensions requires too damn many dots. Sounds like we're thinking along similar lines.

Because anything I do is all kinda overshadowed by the Munich crew, with their (gefühlte) 3000x3000 array...  That think makes the lights dim a little bit when it's switching pixels.  You can certainly hear it.  I'll ask tomorrow if they're bringing it up, but I imagine so.

I'm the other guys with the flipdots :)
Last year (https://twitter.com/twamueller/status/945956528330338304) I also brought my LED display (https://www.twam.info/electronics/led-display), however I'm unsure if I should bring it again as it takes a lot of space

I'm not 100% sure how much space we'll have, but my guess is that more cool stuff is better than less.  

(Edit: I just looked at your project again, with keyboard for scale.  Holy crap that's big.  Still, if you built it, people will enjoy being dazzled by it. :)  I just ordered us a 150x175 cm Jolly Wrencher flag, though, so it'll be in good company.)

If you're not already in the appropriate spirits: a CCC Adventskalender is running at https://events.ccc.de/

BTW: https://35c3.bleeptrack.de/

Theme is "Refreshing Memories" -- which sounds too much like a cola ad to me.

What's the strangest memory we can build?  Rube Goldberg memory?  

I was already going to bring some EPROMs, but now I might have to up my game.

https://hackaday.io/project/11179-ferrite-core-memory-module

I've got some flipdot units, which work by retaining magnetic state.  How are we going to read them?

What else?

What are we all bringing?

@davedarko Hah!  Great minds think alike.  

https://guru3.eventphone.de/event.sh/phonebook?q=hackaday&order=extension

boom :) I copied that from someone from the assembly of @Stefan Kremser 

I'll be at 35c3 and will drop by for sure.

Is a Congress Assembly similar to having a table in a DEFCON Village?

There are bigger clusters, which are mostly regional. If you're not in one of those, then the orga tries to group us together by interest.

I put us in for the hardware zone, basically. 

Awesome!  Drew Fustini (@pdp7) will be at 35c3

nice!

Just saw Drew in Berlin! Thanks for the tip about this assembly Drew!

Fantastic to meet you!  -Drew

Hooray!

thank you Elliot and all at hackaday for this assembly. looking forward to some of your all projects and hacking on my own!

E: many thanks! see you there!

I'm glad to see you there.

You absolutely should! If it's not working, maybe you can get it working over the long weekend.  Or maybe you'll have too much fun doing other stuff and won't care!  :)

My list of last-minute projects that I want to get presentable is longer than the available number of last minutes allows. 

I'm bringing at least: something flipdot, something robot-armish, something <a href="https://hackaday.com/2015/02/04/logic-noise-sweet-sweet-oscillator-sounds/">logic-noisy</a>, something EPROMy, and my usual bag of tricks.

I'm thinking of which of these need an ESP8266 cobbled on, running an MQTT service so that random passers-by can play with them.  Probably all of them, right?
