First part

I also have another series where I experiment with implementing robotics related algorithms using AI tools. Next step is to build some of these robots so I'll start posting hardware related content soon

Can you give me the workflow how you did this

Lovely. Makes me wish @boomsupersonic sold a LEGO Technic kit for kids.

@boomsupersonic thanks Matt

Hi @DilumSanjaya. These apps look amazing. Would you help me make similar ones for a high school tech class? How can I make CAD drawings of tech objects maybe with some animation with vibe coding? Your advice would be very appreciated!

For CAD drawings you can try either @ForgeCAD or @adamdotnew . Although I haven't try those myself, they have some cool demos

@ForgeCAD @adamdotnew Thank you 🙏 I’ll have a look at these.

You are doing really great work!

thanks!

this is awesome! how did you make this?

To put it simply, I usually start with a concept in my head, then use Nano Banana or GPT Images to generate a UI based on that idea. Once I get a design I like, I use that image as a starting point and work with Gemini or other models to recreate it as closely as possible in code. It takes a lot of trial and error, both with image generation and coding, so don't get discouraged if things don't work perfectly the first few times. The main reason I post most of my Gemini experiments here is that I think it currently has the best free tier for people who want to experiment

feel jealous for youngers, they have so many tools to learn

totally!

Part 4 is the signal here. One slick demo is luck. A whole series, with taste for what's worth simulating, is real work.

💯

Cool

do one for electrical engineers

will do in the future

super cool design, love your demos

thanks

😍

Wow.

thanks!

Are you kidding me, this is keep getting better. Amazing!

@k_artic haha, thanks Kartik!

This is crazy cool. 🤯

Could be useful for teaching purposes, lots of opportunity to educate with AI, great work :)

Awesome Sanjaya.

thanks Venkat!

jet stream UI is genuinely brilliant

thanks

This entire series is amazing; it's absolutely unbeatable when applied to education.

thanks !

the reason most people don't build what's really possible with ai is they're stuck on making it 'user-friendly' instead of making the user irrelevant

Looks good to me.

thanks

This made my day!

@designer_tanbir awesome!

That's all great!

thanks!

please stop it, it’s insane!

😂

prompt plz

These demos take a lot of prompts. I usually start with an image as the prompt, and the rest of the prompts are mostly about fixing things and adding small improvements. So, if you want to learn, start with an image that has simple UI components and see what you can do with different LLMs. You will be surprised how far you can get on your own without anybody giving you the prompt. That is the skill I want to promote with my demos🙂

Well, thank you, but how do I convert the elements in the image to 3D using 3JS?

These are sooo cool, and honestly inspiring me to do some crazy shit too 🤪

thanks! that's the goal!

Looks cool brother, can u please tell me how do you build 3d modeling cause , I am currently using free 3d Models which has limitations

For Hunyuan3D, you can generate 20 models per day for free. I purchased a plan for Tripo, but you can message them and see if they're open to sponsoring you. I don't do sponsorships, so I didn't try. Also, I remember you used Sketchfab. There are plenty of really good models there, but unfortunately, their search doesn't work that well.

Thanks brother 😁

How can get accesa and try

So are you going to share the prompt ever?

wow

Is any of your these crazy apps hosted anywhere ?

Using GPT Images 2 for UI and Gemini 3.1 Pro for code is the clean builder split here. The fun next test is whether the airflow sim still teaches something when you add one ugly failure mode, because jets get honest when the airflow goes weird.

UI from GPT Images, code from Gemini, interaction from you — the user who decided a turbofan simulator was worth building and for whom. that creative direction is still the human part.
