A soundbox is a small speaker on a shop counter that announces every digital payment out loud as it arrives, so the shopkeeper knows they’ve been paid without checking a phone. It’s one of the quiet reasons UPI took off in India.

Built a Bitcoin Lightning Soundbox. ⚡🔊

Scan. Pay. "500 sats received."

No custodians. No intermediaries. No permission. Just peer-to-peer money on an open network.

Bitcoin is for everyone.

Thanks @bitshala_org for backing this build.

@tando_me @thebitmela Haha, you're too kind! Had an equally amazing time. Really enjoyed the conversation! 🙌

@vorflux FREE RIDES IN SF
Msg 1 (key): bottom-left row 4056:4F52 464C:5558 = "@VORFLUX".
Msg 2: after stabilising, each byte in that row is one bit (which of its two hex chars is brighter). 8 bits every 30 frames gives 16 bytes: 06 04 0A 17 66 1E 1C 1C 05 05 6F 1B 08 6C 06 1E.

@vorflux A NEW AUTONOMOUS VEHICLE DEV KIT

Msg 1 (key): VORFLUX. The last line of the lower-left panel, 4056:4F52 464C:5558, is hex for "@VORFLUX".

Msg 2 (cipher): VBVBLOQJBFRZOPQSYNNFBYSMPTN
Vigenère-decrypt msg 2 with the key: V-V=A, B-O=N, V-R=E, B-F=W... which gives ANEWAUTONOMOUSVE.

One of the best events that I have attended in a while.

[Bitshala @bitshala_org]

From three days of BOSS Summit in Jaipur to two days on the Bitshala FOSS Stage at @thebitmela, it has been quite a journey.

We went deep into the work: Bitcoin Core, wallet development, Lightning, privacy, Nostr, cryptography, security, open-source infrastructure, and much more. We saw developers take apart difficult problems, share code, run workshops, test ideas, and put their projects in front of the community.

Few highlights: We mined testnet coins with @powdae, raced to claim 36,000 sats through Coconut Wallet, explored fuzzing Lightning implementations with @nishant282003, built with CDK, saw the Formstr stack by @HeyFormstr, CryoBrick by @apalok21, OpenSwap by @citadelfoss, and witnessed the official launch of Shroud by @theanmolsharma_.

We also had conversations that matter just as much: how to teach Bitcoin, build stronger communities, create sustainable businesses, protect privacy, and make self-custody accessible to more people.

And perhaps the best part was watching people learn from one another. First files uploaded to Formster Drive, sats earned, questions asked, ideas challenged, connections made, and new friendships formed.

To every speaker who shared their work, every builder who showed up with something to demonstrate, every attendee who asked a question, every volunteer who made things happen, and everyone who spent these five days with us: thank you 🙇‍♂️

This is what building an ecosystem looks like. Not just big announcements or finished products, but people showing up, sharing knowledge, helping each other, and putting in the work.

We came together to build, and we leave with more ideas, stronger connections, and plenty of work still ahead.

The stages are coming down, but the building continues.

Until next time 🚀🧡

@tando_me That's a really cool idea 😁
will build it.

[Venky @saitamablid]

@tando_me Thank you

What if you never had to scan a UPI QR again?

The soundbox chirps the merchant's UPI ID in near-ultrasonic sound.

Your phone's mic catches it and fills in the payment screen on its own.

No camera. No aiming.

[Bitshala @bitshala_org]

Next up at BOSS Summit: Lightning Sandbox Demo by Duggirala Venkata Sai Viswanath

A familiar idea for merchants, powered by Bitcoin and Lightning.

When a payment comes in, the soundbox announces it, giving the seller an audible confirmation without having to keep checking a phone screen.

Simple on the surface, but it brings Bitcoin payments into the real world, where merchants need quick, clear payment confirmations.

Built something non technical after a long time.

[Sam Altman @sama]

You can skip all the parties, all the conferences, all the press, all the tweets. Build a great product and get users and win.

[Venky @saitamablid]

Such a huge package for such a small thing 🙃

[Venky @saitamablid]

@CaptVenk Awesome work 🙌

This takes me back to when I was around Laksh's age and building a similar project. Mine used Teachable Machine and a camera to detect when to stop mixing based on the food's color and send an alert to turn off the stove.
