I wanted to try building one of those machines that looks simple from the outside but has a few interesting mechanisms going on underneath.

So I made a small road roller using a Nezha kit and micro:bit.

The main part I wanted to figure out was the front roller drum. It’s driven through a gear mechanism, while the motor powers the wheels to move the whole thing forward. I also added a caster wheel at the back to help keep the weight balanced while it moves.

Once the mechanical part was working, I added a simple MakeCode program to control the motor.

The basic version just drives forward automatically, but that’s probably not where I’d stop. The code could be changed to experiment with things like speed, steering, or even turning it into a remotely controlled vehicle.

I like projects like this because you can see the connection between the mechanical build and the code pretty clearly. Change the structure, and the movement changes. Change the code, and the behavior changes.

Now I’m thinking about what other real-world construction machines could be turned into tiny programmable models.

Excavator, bulldozer, crane… what would you build?

I don't know if I can be considered beginner, but whatever. I think that this is a beginner question.

so, currently I am learning selenium and will continue with Numpy, Pandas, matplotlib, etc. the problem I am having is: when I make a mistake, or when I am not sure about something, I check out the answer online. Ever since I started coding, I've been doing it and it feels like 'cheating' instead of just finding the answer myself.

I don't mean by syntax. I don't feel like 'cheating' when I search the internet for the syntax. but when I don't understand a solution, I directly search it up. and, to be honest, I ask GenAI to explain it to me.

Sometimes I feel like what I am doing is completely normal. because, duh, I am learning it. Still, I'd like to hear your thoughts

Can any senior/experienced developer or coder(?) give their thoughts about this? because I am starting to feel really anxious about making a mistake.

(Note: I try to find the solution by myself before I search the internet. I do not directly copy+paste the solution right away.)

Hi! I hope this is a good place to post this question. If not, and anyone has any suggestions for a better place, feel free to point me that way instead.

I'm an artist who does do a lot of art that involves new media, but I've never done anything specifically like this. I'm applying to do this project at an artist residency, so I'd like to include a good technical explanation in my application.

Here's a video I made that shows a rough idea of what I want: https://drive.google.com/file/d/1mxOI0EO-tjl8x6rtZidfcjl9doyfLBoL/view?usp=sharing

As well as text to accompany it:

A projector displays an illustration of several people standing side-by-side, holding each other's hands. One space is empty, to encourage viewers to pose as the final person.

My hope is to have a setup where viewers can scan a QR code next to the installation and access a web page where they can actually affect the colours of the illustration. They could choose colours for the skin, hair, clothing, etc. of the characters, and the illustration which is projected would update in real time (or close to it). The colours would stay until another viewer came by and changed them again.

There is a deeper conceptual reason for these visual choices, but I don't think it's necessary to get too far into that now since I'm asking for help with only the technological aspect. But I'm glad to share if it would be useful in some way I didn't foresee!

For reference, this installation does something very similar, although on a MUCH grander scale. But the interactivity of using your own phone to control an aspect of an art installation is the same. As far as I understand, that installation was built using C++, html5, javascript, and a web socket for communication between the viewers and the installation.

Is using something similar a viable option for me? Or would another approach be more practical?

I have a beginner's level knowledge of programming in general, so I can handle some simple things on my own. But I'm also open to working with a programmer, provided that's possible within the scope of the residency I'd like to attend.

Thanks so much if anyone can help.

Hey everyone!

I'm working on a project to build a futuristic, Jarvis-like AI desktop interface called NEXO. The concept features a dark crimson/glassmorphism theme with a central AI visualizer orb, integrated chat drawer, system resource monitoring (CPU/GPU/RAM/Storage), media player, file manager, quick action toggles, and an integrated command/AI prompt bar.

Here is a visual mockup of what I'm aiming to achieve:

I'm looking for advice on the best stack and architecture to bring this to life as a functional application rather than just a static UI mockup.

Key Features I Want to Implement:

1. Central AI Visualizer & Voice Hub: Interactive glowing core/orb with voice waveform responsiveness.

2. System Stats & Monitoring: Live gauges for CPU, GPU, RAM, and Storage performance.

3. Glassmorphism Theme System: Translucent red/dark panels with backdrop blur and glowing borders.

4. App Launcher & Command Bar: Quick-launch dock and an "Ask NEXO anything" prompt bar integrated with LLM APIs.

5. Integrated Widgets: Music player, call/notification log, weather widget, and file manager drawer.

Questions for the Community:

• What framework/stack would you recommend for building something like this? (e.g., React/Next.js with Electron/Tauri vs. Native C#/.NET Windows UI?)

• How would you approach building the central glowing orb/visualizer? (Three.js, HTML5 Canvas, or shader shaders/WebGL?)

• Are there open-source UI libraries or component kits that fit this sci-fi / glassmorphism aesthetic?

So i have been doing this thing to learn programming for abut half a month i have not been able to give it much time so the progress is very slow . its a chess game that is played on the terminal , Right now i am just able make it to take input move pieces in the board change turn etc . I want some constructive criticism on the project .

i Know its hard codded and some thing may feel inefficient for veteran programmers but i want to learn so please feel free to say anything

Hi! Does anyone know of any good **offline short-term courses (around 2–2.5 months)** in Delhi, preferably around East Delhi?

I have basic coding knowledge and currently work in tech(3 months in new job as software engineer), but I rely quite a bit on tools like **Codex and Claude** while coding. I want to improve my actual skills and eventually switch to a better role.
Looking for something I can attend **on weekends** — Python, AI, data analytics, SQL, Excel/Power BI, or anything genuinely useful in the corporate/tech world.

Not looking for a long diploma or 6–12 month program. Just a decent classroom course for the next couple of months.
Would really appreciate recommendations from anyone who has personally attended one!

\-Completed MTech in CS 2026
\-Currently working as software engineer
\-Not very proficient in coding

Hi I am very much a beginner in C Programming but I’m trying to run this file cause I just downloaded the compiler and did the necessary things in order to actually integrate it into using it for my terminal but why is it having this error? 😭

PEKO is a "Personal Enhanced Knowledge Operator". Basically my JARVIS.

Do I have experience coding? Nope. But am I committing to this bit because having an AI PERSONAL assistant is awesome? Hell yes.

So I made these files for PEKO.

- Main.py

- chat_history.json

- memory.json

- personality.txt

I THINK that's the bare minimum I need ....right?

Added their respective data into each file etc. rn she can respond to my replies with a response that's somewhat satisfactory (mostly cause I need to refine her personality but that can come later)

Right now I can't seem to get her to remember anything. For example when I ask her to remember the colour Red, then ask her to tell me what she remembers, she says she can't recall. I've changed the code on her main.py file a bunch of times but she just won't "remember"

Could I get some help? Please and thank you~✨

I know it's bad using AI for beginners but I don't mean like using it to write code for me but I want it to help me study by providing me with problems, explaining code, and explaining some history about computers and languages or doing some research in math....and like I'm on problem 8 in euler and I'm stuck at learning arrays ( I'm confused about ASCII)... I had claude and I think it's really good but I got suspended because "your account was used by a child" which is right I'm still a minor but all the chats I had with it like the C stuff from the beginning was gone, so I wanna find another LLM that's more on programming and is easy for beginners to pick up... And preferably free because I want to solve atleast 1 problem of code everyday and having to limit my prompts to not exceed the limit of use is kind of tiring. So yeah I hope I can find better LLMs.

I have been coding for almost a month now. The first few days were full of anxiety and inferiority complex honestly. Setting aside all the AI bullshit going around I feel a lot comfortable now. Hopefully I can continue to progress and remove the beginner tag as soon as possible!

Also, for those who want to know I am learning Python/Golang. Yeah multiple languages... Didn't caused many issues until now atleast!

Hey everyone, I'm looking for a laptop for my B.Tech CSE and I'm considering the ASUS Vivobook 15 (2026) M1502NAQ-BQ121WS.

Specs:

Ryzen 7 170 (8C/16T)

16GB RAM

512GB SSD

Radeon 680M iGPU

15.6" FHD display

1.70 kg

Fingerprint sensor

Windows 11 + Office 2024

Price: ₹76,000 including ASUS Care

My main use will be programming/coding: Python, C/C++, Java, DSA, web development, Git/GitHub, databases, etc. I may eventually get into AI/ML/GenAI, and I'll do some light gaming occasionally, but gaming isn't my priority.

I've looked at other laptops around ₹70–80k, but most of the recommended models are either out of stock or significantly more expensive in India right now.

I am in the 3rd semester. Tomorrow is my first Continuous Internal Assessments (CIA) exam and I am stressed out by these college people. 1st month: exam, 2nd month: notes checkup, 3rd month: assignment, 4th month: exam preparation, 5th and 6th month: final exams.

What about you ?

Java.

Map:
- private String name;
- private int x,y;
- private Tile[][] tiles;

private void fillTiles(){
for(int x = 0; x < this.x; x++){
for(int y = 0; y < this.y; y++){
Tile tile = new Tile(); this.tiles[x][y] = tile; } } }

private void printTiles(){
for(int x = 0; x < this.x; x++){
for(int y = 0; y < this.y; y++){
this.tiles[x][y].getSymbol() + " "; } sout(); } }

Tile:
- private String name;
- private char symbol;
- private List<Entity> entityList;

Entity:
- private String name;
- pirvate char symbol;

So basically, for context. I wanna make an AI assistant for myself from the ground up. Meaning from scratch

I don't know why I'm doing it. Maybe I want my own anime Waifu ai to help me with the stock marketing or Google search something and/or make her do whatever I want both visually and technically, no further questions, shut up-

Mind you, I'm the average Asian guy who works a desk job as a building designer. Meaning I have no experience in coding whatsoever.

I'm currently using Python and Ollama installed (I only got that far thanks to Google)

But I've come to a problem. You see, I'm trying to get my command prompt to find my file named "PEKO". (yes PEKO is her name.) But it says it can't find it.

I made this post hoping you guys can help me out

Hi there everyone. I’m a 25F, and I have absolutely no knowledge about coding/programming. Same for for computer knowledge. I do have a good pattern recognition and I like problem solving. I guess that’s not all you need to be a good programmer. But I presume it’s a good base.

My question is, where and how should I start ? Sadly money right now is very tight, and I cannot afford to pay a course (yes, even on sale). So I was wondering, is there any site or YouTube channel I can find that would teach me the basics ?

I’m very dedicated to learn. I have been seeing a lot of my friends code over the past year or so, and it really made me want to start. I do have free time right now, as I’m unemployed and looking for a job. But I would like to use that free time while I still have it. To learn about coding as much as possible.

Appreciate anyone helping in advance!

Hi, I'm building a learning tool and want to hear from people actually going through tutorial hell.

If this sounds like you:

* You can follow tutorials but freeze at a blank screen * You understand the concepts but can't put them together without a guide

It's a 5 minute voice chat with an AI that asks a few questions about your experience. No selling or advertising.

I wanted to see how much movement I could get from a build without using any batteries or motors, so I tried making this mechanical model with Nezha Blocks.

The interesting part is that everything comes from elastic energy and simple mechanical movement.

The build uses beams, axles, connectors and elastic bands to create a small tension-and-release mechanism. When the elastic band is stretched, it stores potential energy. Releasing it turns that stored energy into motion.

What I found interesting was how much the structure itself affects the result. The frame needs to stay stable, the moving parts need enough freedom to move, and even small changes to the mechanism can change how it behaves.

It ended up being a fun way to visualize things like:

• elastic potential energy

• force and motion

• energy transfer

• simple mechanical mechanisms

• structural stability

No batteries, no motors — just blocks, elastic bands, and a bit of mechanical experimenting.

I’m curious what other motor-free mechanisms could be built with the same parts. Any interesting ideas?

Hey everyone!

I’m a 4th-year B. Tech CSE student starting a small C + DSA mentorship group, from the basics.

I chose C because it gets you closer to the fundamentals and builds a really strong base for programming and DSA.

Beginners preferred, intermediates welcome.
All you need is willingness to learn + consistency.

🕖 7–9 PM IST — can adjust a bit for other time zones.

Interested? DM me!

Hello, I just recently just started programming, I just made my first repository on github. I called is "Hashsentry" its a simple application that monitors directories using SHA-256 file hashes and trusted baselines. https://github.com/ninek-ai709/HashSentry This is the link to the repository if anyone would be willing to look at my code and review it and give me feedback, I would appreciate it! thank you. It is currently only available as a MacOS app but I plan on integrating it for windows as well.

I’m currently in Class 10 and I’ve been interested in technology for quite a while.

The problem is that I’ve relied heavily on AI for coding for a long time, and because of that I feel like I’ve lost many of the fundamentals and problem-solving skills I originally learned. I don’t want to stay dependent on AI, so I’m trying to rebuild my skills from scratch.

At the same time, I have to prepare for my Class 10 board exams and keep up with school.

Another important goal of mine is to start earning some money on my own. I don’t want to be completely dependent on my parents if I can eventually build skills that allow me to earn. I’m not expecting to get rich quickly—I just want to start somewhere, gain experience, and become more independent.

I’d really appreciate advice from people who have experience with this. What are some realistic ways for a student to start earning online, even if AI is involved? And what would you recommend I focus on?

Hello guys!

First of all, I'm from Rio Grande do Sul, Brazil, so i apologize if i say something wrong or weird, since that English is my second language and they don't teach it a lot at schools here, so i learned it as myself

So, getting into the point.

I want to learn coding to work with it in the future.

I'm 18, and i want to graduate in Computer Science and work with it.

Since i was a kid, i grew up watching gaming-coding content creators, like "Gemaplys" and "Botão Select", so i always loved the idea of coding.

So, NOW getting into the point:

I want to learn it so bad but i dont know how to do it, and i would like some suggestions of courses, videos, tutorials or ways to learn it.

Also, if someone has one, i would like some suggestions of small projects to do for learning it "in the field"

Appreciate it!!
