They're a fun thing to play with. 👍

Hi Alex, they are small split pins also called brads. Just like the normal brass fasteners but small! These ones are 4.5mm diameter and 8mm long I got them from eBay but I've seen them in craft shops in the UK

Go for it! 😎

So exciting 🌞

Lovely @robives.bsky.social dragon linkage mechanism. Next step: recreate with my acrylic linkage kit and add servo control. 😀🏴󠁧󠁢󠁷󠁬󠁳󠁿 www.robives.com/project/drag...

That looks great! Thanks for sharing. Looking forward to seeing the servo powered version 🐲❤️

Safe travels Lucy!

Double Geneva Mechanism. A paper project for you to download and make. For each turn of the crank the index wheel advances quarter of a turn twice with a short pause, or dwell, between each movement. #automata #paperengineering #EssentialMechanism www.robives.com/project/doub...

Prototype for updated logic goat project. The geometry on the rear leg linkage needs a bit of work. I want it to really kick! #maker #paperengineering #PaperAutomata #prototype
