Feather like Previewer

Raj Verma — Wed, 18 Feb 2026 07:46:18 +0000

I am trying to publish something on npm to get the taste of opensource development but could never due to lack of time or the right idea.

So while working on another project which required reliable way to preview files in some sort of googleish way.

And lack of existing libs forces me to built one myself.

And it suddenly hit me that "why not to build it like an independent module which i could later publish as well".

so i built one under 15kb

So now when ever you feel you need a way to preview files in a structured way visit npm/iammrverma

Use it, share your thoughts, find bugs, happy coding :-)

What AI Hardware Could Actually Look Like: A Vision for the Smart Band Interface

Raj Verma — Sat, 05 Jul 2025 05:17:17 +0000

AI is quickly moving beyond screens, chat boxes, and our desks. The next frontier is not just artificial intelligence on a device — it’s AI as the device. Integrated. Embodied. Ambient. And always close at hand.

In recent months, we’ve seuen a wave of interest in AI-integrated hardware — from AI pins to smart glasses — each attempting to bring the power of large language models into our physical world.

But what would it take to create an AI device that people would actually wear and trust, every single day?

💡 The Concept: A Smart Band with Tap-to-Activate Fingerprint Scanner

Instead of relying on wake words or passive listening, this smart band would prioritize deliberate activation, biometric trust, and voice-driven intelligence — all without a screen.

Key features:

✅ A nearly invisible fingerprint scanner embedded on top of the band
👆 Tap / double-tap / hold gestures for different interaction modes
🔒 Biometric verification tied to each gesture — for personalization and privacy
🗣️ Interaction via voice, haptics, and secure BLE, if needed
💤 No always-on microphone, no wake words, and no display

This interaction model has major benefits:

Reduces false activations
Bypasses privacy risks of passive listening
Feels familiar — similar to how people already use fitness bands or smartwatches

🧭 Why Not Other Form Factors?

A few alternatives have already hit the market — but each carries tradeoffs:

🔘 Chest Pins (e.g. Humane AI Pin)

While bold and futuristic, AI pins have faced skepticism around real-world usability, price, and always-on perception.

🕶️ Smart Glasses (Meta/Ray-Ban)

These offer potential — but still suffer from social friction and privacy optics. Glasses are visible, expressive, and not always acceptable in all settings.

🪢 Why the Smart Band Makes Sense

Unlike pins or glasses, smart bands are:

✅ Already normalized — millions wear them for steps, sleep, and time
✅ Ergonomic — no added bulk or awkward placement
✅ Private — no visible lens or mic
✅ Gesture-first — embraces intentionality without screens or distractions

This form factor allows AI to blend seamlessly into daily life. Not flashy — just subtle, useful, and trusted.

🌱 A Contribution, Not a Pitch

I’m sure companies like OpenAI and others are exploring this space. This isn't a product pitch — just a sincere idea rooted in curiosity and human-centered design.

As AI moves from screens to embodiment, we’ll need to think more like designers — not just engineers. This smart band concept is my small contribution to that conversation.
