Mark Wyner Won’t Comply 
This is bound to bring some joy to your day. Everything about it is delightful.
(And the engineering is amazing.)
#Joy #JoyScrolling #Happy #Laughter #Play #Engineering #RollerCoaster
So…y’all really liked this. And that was the whole point. It brought me instant joy so I wanted to share it. Seeing y’all love on it as well fills me with happiness.
With all the bad stuff happening, we have to remind ourselves why we fight th me good fight. Laughter and smiles. Those are two really good reasons.
Tirrimas 
🚫👑@markwyner and that EVERYONE deserves that joy
azteclady@markwyner would you mind terribly adding the joy scrolling hashtag to the original post? It makes it easier to find the post again when one needs an infusion of joy.
ETA: THANK YOU!!!!
@herhandsmyhands oooh, that’s nice. I didn’t know that was a thing. Done. Thank you!
@markwyner 🙏🏾
Given the existence of doom scrolling, I thought a happier alternative would be a net good, and I'm glad to say other people have adopted it to great, joy-inducing effect.
AI6YR Ben@markwyner Hmm, I wonder what kind of gearing that requires on an exercise bike to pull a human up something like that. 😂
@ai6yr seriously. I zoomed in to look. It appears that the bike is only turning the axle. Then the rest of the work is done by pulley physics.
Bracken@markwyner @ai6yr there's no visible pulleys. The bike is connected to the axle, I think instead of the flywheel, using it's original chainring, with some unseen ratio, probably via a chain. Then there's another gear reduction from the axle to another short axle above it, which pulls a different chain around the ramp. The carriage engages with this last chain.
@bracken @markwyner Pretty cool! It would be neat to learn how to set those up (for no other reason than understanding building gearing/bicycle driven equipment).
Oh, man. You said it. It brought me great joy just to watch this. But immediately after, my brain went to the engineering.
Someone posted this link to more info about it:
@markwyner @bracken You can buy these on Alibaba? LOL (that's not as fun though)
Rolf Steinort (314.8 ppm)@markwyner @ai6yr She did about 20 rotations to pull the car up the ramp. As a foot travels around one meter per rotation on a bike she does about 20m to get about 3 m of ramp, reduction by 6 to 7. It’s a bit difficult to guess the dimensions.
@rstein @markwyner Oooh, fun. I should learn more about gears. And welding!
COD
Seb@ai6yr @markwyner same as riding a bike up a hill with your own weight on it I suppose
nigel@markwyner I need to make one of these
@nigel serious.
astroPugI would totally use this
EyeThis is great! 👏👏
Bryan Beal@markwyner
Thanks a tonne for sharing. I needed the joy today.

Anselm "Two Sheds" Schüler@TheBeal @markwyner TIL people say "thanks a tonne", I've only ever seen "thanks a ton"
Yeah, all good. My generation spell it the old way. I guess "ton" is the more modern spelling.
Erwin Wessels@markwyner @lkanies such lovely plain joy ❤️
Joe B@markwyner Was
About to log off then I saw this.. funny! time for more doom scrolling Lol

Court Cantrell prefers not to@markwyner GLORIOUS.
Also, I need this in my back yard. ***NEED***.
@courtcan need. Agreed.
Logan 5 and 999 others@markwyner I love it! Any chance you could add some alt text?
@LoganFive I always do. And I did. It’s there. Are you not seeing it?
@markwyner Terribly sorry. I was looking for the alt text icon but it is showing up when I hover. 👍

@LoganFive rockstar. And no worries at all. You’re good. I was just concerned that it wasn’t showing for you. That would have made me sad.
George BI have noticed that alt text is not visible on videos in the web UI at least for some instances.
Here are screenshots of this post in the official mastodon app and the web UI. Note that the alt button is visible in the app but there is no equivalent on the web version.
catflyhigh@gbargoud
This is true, there is no Alt button to clips on the web interface. BUT: with mouseover the alt-text appears. So this should not be a problem. 🙂
Oh, I see. Yeah, that’s it. The little “alt” button is not in every UI. And it’s not necessary. While the alt text is helpful for people who are visually-enabled, it’s there for people who have visual disabilities. The graphical button overlay and the hover aren’t critical.
Sounds like some sort of bug to me. I wrote it, and it’s there. Do you see alt text on other posts in those same browsers/apps?
I recommend reporting that bug as an issue on the Mastodon GitHub repos:
https://github.com/mastodon/mastodon/issues
https://github.com/mastodon/mastodon-ios/issues
I would, but I can’t because I see the alt text in the web UI and in all seven of the Mastodon mobile apps on my mobile.
I've noticed that the link to read it is missing on videos on the website on my phone browser but haven't investigated much further.
According to someone else in the comments it does appear on the tooltip when hovering over it with your mouse if you're on a computer and I'm pretty sure it is reachable for a screen reader so it:s not a huge bug but would explain why it didn't show up for everyone.
It’s absolutely available for screen readers.
Also, this is a video so there’s no alt tag. The default video accommodation is captions. But alt text can be added with something called an “aria-label.” A screen reader will read this the same way it reads alt text.
Andy Fletcher@markwyner the best bit was everyone was evidently having immense fun with the thing.
dummzeuch@markwyner the most important information is missing: Where is this?
Cryptomon@dummzeuch @markwyner there are at least two of them at "Karls Erdbeerhof" near Berlin, but my daughter's legs were too short to move her brother
Johan Saxe@markwyner I might possibly need to buy this thing.
Jeff McNeill@markwyner Ok, my children want one, where are the manufacturing plans?
@jeffmcneill @markwyner There are also other short Clips on yt of the exact same build. So there must be a plan somewhere 🧐
@Ginseng @markwyner There are options to buy this on Alibaba, the original plan seems to have been a Chinese father.
proedie@markwyner Did the two build it themself?
@proedie no idea. I don’t even remember where I found the video.
@markwyner Found it: https://www.alibaba.com/product-detail/China-Factory-Cheap-Human-Unpowered-Bicycle_1600873221112.html
It’s so cheap, I’m glad I have no garden. I would totally order this today!

woollypigs@markwyner hours of fun
your auntifa liza 🇵🇷 🦛 🦦@markwyner i neeeeeeeeeeds it! i waaaaaaaaaants it!
WasdNedSagsd@markwyner amazing
Daniel Hernández@markwyner Yeah, very nice engineering. Where is it? In the Christmas market in Esslingen am Neckar, I have seen many mechanical games moved by humans, mostly made of wood.
most_definitely_human@markwyner Maybe this is a starting point: https://youtu.be/SsrfBxWYxOQ?si=Af5q6yk6ayKEewzW
It's not the same model, but it is homemade
