ripperThere's still some time to procrastinate packing camping stuff... right? 🤔
Aaaand off we go!
Looking forward to finding out what I forgot to pack

eep! on the train
✅ Train 2/7 to EMF
Hüfe, dea Zugbegleita redt jo boarisch.
✅ Train 3/7 to EMF
TGV - Train à Grande Verspätung?
✅ Train 4/7 to EMF
✅ Train 5/7 to EMF
Thanks @vagina_museum, the "Museum of Mankind" exhibition was really funny! Now, let's get back on track.
✅ Train 6/7 to EMF
From the train I saw many puddles in the fields... I guess this year EMF stands for Extra Muddy Field?
✅ Train 7/7 to EMF
Spending some time in the Ledbury Tesco parking lot before getting a shuttle to the camp site is definitely an important part of the EMF experience. :D
#emf2024 is amazing, you spend 2h putting up chairs at Stage A and everything looks different. It's a proper camp now. :O
Sooo I heard the people at #emfcamp like camping? Luckily there's @hackmas taking place in August in Austria!

Oh, I still have photos from #emf2024 I wanted to share. People brought sooo many funny, hacky, cool builds.

Speedy tren did its job, I'm back in Europe. Now I have about 45 minutes to catch my Nightjet to Vienna. Whoop whoop
But also... How complicated can travelling by train be?
Eurostar: Yes!

Well, that's great. The NJ is here. But... It's missing half the coaches, apparently they're stuck somewhere in Germany and supposed to be added in Mannheim. At ~1:00 in the morning. Until then, they stuff everyone into one single seating coach. Argh.
We got thrown out of the train and then the same conductor asked us to get back in. Fun, fun, fun
We are moving! 👀👀👀
Morale is high. We're having good conversations in the compartment, learnt a lot about railway safety and operations and there's beer. Could be worse. :D
What's kinda funny about night trains is... Everyone I ever met there is super chill about delays and other inconveniences. Like, right now, our carriage is missing and everyone is like: "Here's a story about a rail travel I took which was a lot worse. And it was great fun!"
Great. There are now people boarding the train wanting to have their seats. And they are pissed that we're occupying them because we were told by the conductor. Exactly what you need at 1:00 in the morning.
Ooof. They didn't find a sleeper in Mannheim. Great.
Changed train in Linz, maybe that one stays on time.
Next to me are some punks. I mean proper punks. But they are talking about project controlling meetings and buying a house in Italy.
So I guess... Punk's not dead, punk's got a job in controlling and is buying houses.
Finally made it home. \o/
The thread isn't finished yet, though. Once I'm showered and relaxed, I'll post more pictures from EMF and the one day we spent in London afterwards. :)

Well, fuck. I guess beside all the good memories, an awesome badge and a light sunburn I also got COVID at EMF. :/
Ok. Moar pictures of contraptions!
James Bruton ( @XRobotsUK ) brought a... thing. It's a three-wheeled tentacle robot. Absurd and amazing!
A lot of vehicles, some of them competing in the hacky racers series!
A tracked trike which worked really well on the grass and dirt.
And someone had a real fighting robot with them!

By the way... The second picture shows Matt Denton on his Lego-inspired motorbike. He finished it on site and also made a video about the first part. And cought me while I was admiring the tentacle thing from the first picture. :D

At EMF there's always a lot of beautiful art projects. That's not even remotely all of them and they were all amazing.

Next to one of the ponds there was the EMF sign. Picking up this year's solarpunk theme, it had some water games on there, circuit boards, bubbles in the numbers.
And there were of course more colourful LED installations!

Somehow I forgot to finish this thread... So there's still a lot of cool pictures from #emfcamp which I want to post.
Let's start with the nullsector, EMFs party area. This year's theme was solarpunk and picked up in a really cool way.

Nullsector is really nice at day but it really comes to life at night. That's also when the nightmarket opened, an area where some small maker businesses sell electronics, kits, jewellery and similar.
And then there's lasers!

After EMF we spent a bit of time in London. Went to Chinatown and Soho on Monday to get some food and drinks.
And on Tuesday we visited the barbican complex. As I don't know a lot about it, except that I find it architecturally impressive, I won't add more and let you enjoy the pictures.

We also had a short peek into the barbican, a theater inside the complex. Although there were preparations going on for some event I guess it was still equally impressive as the whole complex.
And that ends my (kinda chaotic) thread about my journey to EMF and back. Thanks for following along and I'm glad so many of you liked the pictures and posts. :)
lucas payton@ripper I never saw the prisms. What were they up to?
@GaspodeTWD they appeared in the lounge at some point. I don't remember what they exactly did but they lit up and looked beautiful.
Jonathan Hogg@ripper @GaspodeTWD it was a piece called “Fireflies” that got added during the festival after the artists, @C_Bugs_B, came up to me and asked if we could place it
Bugs@GaspodeTWD @jonathanhogg @ripper Thanks! (And thanks again Jonathan for getting us set up at no notice!). On its own, each lantern blinks from green to gold every few seconds. But when it sees another lantern blink, it slightly shortens the interval; over several cycles, this is enough to make the swarm gradually drift into sync. It's the same way firefly swarms synchronise.
@GaspodeTWD @jonathanhogg @ripper They "see" each other via an ESPNow (WiFi-ish) signal which each sends out when it blinks. This also carries variables so I can send updates (colours, blink intervals, etc) from a remote and have them propagate through the swarm. There's a chance one will blink out of time to make the pattern collapse back into chaos periodically; there was also supposed to be a noise sensor so they could be startled by loud bangs, but the sensors I bought were crap :D.
@C_Bugs_B @jonathanhogg @ripper that sounds fantastic, sorry I missed it. I guess in theory there's not really a swarm limit if they're just listening?
@GaspodeTWD @jonathanhogg @ripper I think the logic can work up to any number, but the ESPNow protocol is limited to, er, 20(?) peer devices. I assume someone who knows networking could use a better protocol for more devices. (My first attempt was just using cheap 433mHz modules, but there was collision/cross-talk when they synchronised too closely, so I think some sort of networking protocol is necessary to avoid that.)
@C_Bugs_B I’ve not played with the ESPNow stuff. What language do you program it with? I’ve done a bunch of ESP32 stuff with MicroPython and using Bluetooth to synchronise multiple devices
@jonathanhogg I was using Arduino language, in which the ESPNow stuff which has nice libraries and, crucially, some well-written how-to articles. Bluetooth didn't occur to me, maybe it'd be good? I've no idea about how the pairing works or whether you can do general broadcast. (And now I type that, it sounds like a job for mqtt, but I'd lose the decentralised aspect). Mostly, I used the esp8266s because I had a handful left over from a beginner's workshop I ran with them years ago.
@C_Bugs_B I’ve actually not been secure pairing them. I run serial over Bluetooth and then a mesh network over that involving temporary point-to point connections between nodes. It’s super hacky but enough to get discovery, time synchronisation and distributed OTA updates working. I have been meaning to switch to a WiFi mesh network, but not found the time…
leah, trout arc 
@mae thanks! :)

Daniel Bohrer@ripper ob no 🥴 wish you a good recovery!
@daniel_bohrer Thanks, luckily it's been quite mild so far
Sandzwerg@ripper get well soon
@sandzwerg thanks! :)
