Blink: $11.99/mo? Nah. I Vibe Coded a Raspberry Pi Instead How I built Watchman: a Pi Zero 2 W USB gadget pipeline to archive Blink clips locally and unsubscribe from one more recurring fee

Just in one weekend. No cloud. No subscription. Pays for itself in under 3 months. Code is open source.

So I grabbed a $25 Raspberry Pi, fired up GitHub Copilot, and vibe coded Watchman -- a Pi that impersonates a USB drive for Blink, intercepts clips as they're written, and archives everything locally with a simple web UI.

Amazon charges $11.99/mo to let you watch your own Blink camera footage. Their ToS lets them copy, modify, and review your recordings. Hard pass.

The End of the Digital Wild West: Understanding Brazil's New ECA Digital Brazil's ECA Digital is now in effect — one of the world's strictest laws protecting minors online. What it means, why it matters, and how it fits into a global movement.

Brazil’s new ECA Digital is now law.

No more "I am 18" checkboxes. No more infinite scroll for minors. But there’s a catch: to protect kids, are we building a surveillance nightmare where every click is tied to a government ID?

It turned out to be a fun experiment and a great way to keep everything local in my Home Assistant setup.

(1/2) Cloud-dependent smart plugs = more data exposure + bigger attack surface.
Local-only with Tasmota = privacy, resilience, and control.

So, last weekend I decided to tackle a new DIY project, I flashed a Sonoff S31 with Flipper Zero to cut the cloud out entirely.
