Ah, Lego, the plastic toy enjoyed by adults and children all over the world. While we’ve previously written about amazing Lego Mindstorms projects, are you out of luck if you don’t have sets like Mindstorms EV3?
There are many great projects you can build without Mindstorms. Here are some of the best.
1. Large contraceptive

This amazing contraption is the work of YouTuber akiyuky. Featuring pneumatic pumps, conveyor belts, robots, trains, lifts and more, it’s a great combination of engineering and ingenuity.
What’s even cooler about this car is that it feels completely mechanical. There is no Mindstorms computer or brain to control functions, it is controlled by motors, gears and timings.
Although this is a Rube Goldberg machine, as it serves no real function other than looking cool, it is still a brilliant piece of Lego building.
2. Coin pusher arcade game

This neat arcade game came to us thanks to the Let’s Do This YouTube channel. With a simple motor and gearbox, you only need a few special parts to do it yourself.
Not only does this machine work like a fully featured arcade game, but the video will guide you through the different parts of the machine. Once again, this project is purely mechanical and requires no programming at all!
3. Drawing machine

This amazing pattern drawing machine was built on the JK Brickworks YouTube channel. This model, available in quantities of around 100 pieces, looks simpler, but the results are still impressive.
Using just a motor and some gears, you only need a few non-Lego supplies like a pen and a rubber band. Detailed detailed building instructions are available for free and are so well written that they could have been written by Lego itself.
Simpler is always better, which is why this machine should be on the list for design purposes only.
4. Steampunk Pleasure Boat

This project also comes to us from the skillful hands of YouTube’s Lego channel JK Brickworks. Based on Theo Jansen’s Strandbeest, this amazing Lego machine requires no brains to operate.
Although this model is purely mechanical, it requires special parts such as motors and batteries.
This build is certainly tricky, but once again the creator has provided clear, detailed instructions on their website. While the build guide doesn’t show how to build the entire model, it does cover the walking mechanism — the hardest part!
5. Tank with remote control

Okay, so this project is a bit of a cheat. This project uses Arduino like his brain. While it may go against the idea of Lego, it still makes for an incredible project.
