Block coding, a real-physics circuit bench, a PCB lab that exports fab-ready Gerbers, and real Python — one platform where a K-12 student's idea becomes working code, a tested circuit and a manufacturable board.
Why it exists
The studios
01 / Block Coding
A Scratch-style editor built on Google's Blockly. Sprites and costumes animate with real poses, and the same blocks reach out to real boards.
02 / Circuit Bench
A circuit simulator with real voltage and current physics. Students wire real parts and run Arduino-style code against the circuit they built.
03 / PCB Lab
Schematic capture and board layout in one studio. Students design a board a real fab house can manufacture — and learn why the rules exist.
04 / Pro-Track
CPython compiled to WebAssembly via Pyodide, running right in the browser — with the libraries real data scientists use.
One project, four studios
Follow one student's night-light project across the platform. Same class, same login, same progress view.
In Block Coding: when it gets dark, switch the light on. Events, sensing and a loop.
On Circuit Bench: an LDR, a resistor, an LED and an Uno. The simulator flags the missing resistor before anything fails.
In PCB Lab: schematic, layout, routed copper, a clean DRC — then Gerbers a fab can make.
In Pro-Track: log light levels, plot them with matplotlib, and let Copilot review the code.
Who it's for
Schools
School accounts and an admin panel. Runs in any modern browser — no per-machine installs, and simulation means fewer consumables and burnt components.
Teachers
Copilot handles the first-line “why doesn't it work?” so you can teach.
Parents
Parents follow along with WhatsApp notifications.
Students
Experiment freely — nothing breaks in the simulator. Hints when stuck, not answers handed over. Light and dark themes, in their own language.
Compare
Scratch, PictoBlox, EasyEDA and KiCad are excellent tools. They were never designed to be one curriculum.
| What a STEM class needs | Stitched together | Trineetra Fusion |
|---|---|---|
| Block coding | Scratch or PictoBlox | Block Coding studio |
| Circuits & hardware | PictoBlox plus physical kits | Circuit Bench, real-physics simulation |
| PCB design & Gerbers | EasyEDA or KiCad | PCB Lab with ERC, DRC, Gerber export |
| Text programming | A separate Python IDE | Pro-Track, real Python in-browser |
| Accounts & progress | Different for every tool | One class, one login, one view |
| AI help | Varies by tool | Techvein Copilot across studios |

Made to travel
The whole interface in six languages, with light and dark themes. A classroom needs only a browser and a connection.

FAQ
No. Trineetra Fusion runs in a modern web browser at app.trineetra.com — including Pro-Track's Python, which runs inside the browser itself via Pyodide.
Yes. PCB Lab exports Gerber files — copper, solder mask, paste, drill and board outline — the standard format PCB manufacturers accept.
Circuit Bench models real current and voltage, so an LED without a resistor or an overloaded part raises an over-current warning, just as it would fail on a real bench — without anything burning out.
Circuit Bench includes Arduino Uno, Nano, Mega and ESP32 alongside a wide range of sensors and outputs, and Block Coding includes hardware blocks for Techvein's K-Bot and other boards.
An AI assistant built into the studios. It gives hints, explains errors and reviews code — coaching students rather than handing over answers.
Parents can see their child's progress, and the platform supports WhatsApp notifications for parents.

With his blessings, today we stand at an important milestone for Trineetra.
After 65 intense days of building, testing, correcting, improving, breaking and rebuilding, Trineetra is ready to go live on 1 October 2026.
What started as an idea is now a real classroom platform - bringing Block Coding, Circuit Bench, PCB Lab and Pro-Track together in one place, ready for students, schools and teachers.
Before we open it to the world, I request everyone to spend some time with the product. Open the site, try the studios, go through the flows, read the text, and look at it with a sharp eye.
If anything feels incomplete, confusing, broken, slow, or not worthy of launch - please raise it now. This is our last easy window to fix things before real users come in.
A heartfelt thank you to the people who helped bring Trineetra here:
Trineetra has not been built by one person. It has been built by the spirit of the whole team - managers guiding their teams, testers pushing hard, developers fixing again and again, and everyone accepting one more round of work when the product needed it.
If I have missed thanking anyone by name, please forgive me. It is not intentional. Every contribution matters, and this milestone belongs to all of us.
| URL | Purpose | Accounts |
|---|---|---|
| trineetra.com | Production - real students, real schools, real data. | Do not create dummy or test accounts here. |
| code.techvein.org | Staging - internal team testing only. | Create test accounts here and test freely. |
If you want to explore, test edge cases, or try to break something, please use code.techvein.org. Production is for real users only.
With Mahadev's blessings, we now take Trineetra live.
This is not the end of the work. This is the beginning of our responsibility.
Har Har Mahadev.
With Gratitude,
