Show HN: Home Cam – turn an old iPhone into an offline hidden security camera

chrisBHappy — Thu, 19 Jun 2025 12:13:18 +0000

I built Home Cam because I needed a security camera I could trust. Every app I tried either streamed to someone’s server or buried analytics in the code.

What it does: • Turns any iPhone (iOS 15+) into a motion-activated camera • Records locally up to 4K 60 fps, stores clips in an AES-256 vault • Works fully offline by default so nothing leaves the device unless you enable iCloud Photos • Discreet modes: fake calculator screen or pure black (coming soon) • Battery Saver dims screen and throttles sensors for longer sessions

Why it might interest you: • No signup, no ads, no trackers. Privacy is the core feature. • Built entirely in Swift/SwiftUI. • I’m a solo indie dev & feedback from HN has shaped many of my past projects.

Yes, I love the idea of gamified learning. I've been working in my free time on gamified learning of git. Will call it something like "Git Commit Crimes". After receiving such a positive feedback for SQL Noir I'll definitely continue to make such games. I might also think about making one for Python since that was requested a couple of times.

Show HN: SQL Noir – A detective game where you learn SQL by solving crimes

chrisBHappy — Mon, 07 Apr 2025 10:16:36 +0000

I posted about SQL Noir a while ago — it’s an open-source game that teaches SQL through narrative-driven investigations. You act as a detective solving crimes by writing real SQL queries against actual databases.

Since then, I’ve added 2 new cases (now 6 in total), improved the UX, and fixed a bunch of early issues thanks to community feedback.

It’s still 100% free and open source. Would love feedback on the new cases, or ideas for future mysteries.

No, I haven’t, frankly, I didn’t even know this existed. Thanks for the tip!

I’ve been a long-time reader of Lobsters and would love to become an active part of the community. I’m especially into developer tools, learning platforms, and building small, thoughtful projects.

If anyone has an invite to spare or advice on how to get one, I’d be very grateful.

Show HN: I built an app to teach my toddler 30 languages in just 10 min/day

chrisBHappy — Wed, 12 Mar 2025 21:45:03 +0000

I wanted my toddler to benefit from early exposure to multiple languages but struggled to find a simple, engaging tool. So, I created 'Learn Colors - In 30 Languages,' a minimalist app designed specifically for toddlers.

The app helps children learn basic colors through interactive play, high-quality audio pronunciations, and a clean, minimalist design. Each language features carefully generated voiceovers from ElevenLabs for every color and phrase, with each audio file reviewed for accuracy and pronunciation.

I'd love to hear feedback from the community, especially from parents or those passionate about language learning for kids.

Just implemented it. Looks really nice on Desktop. Nice and compact.

Yes! I just implemented a "Side By Side" view that will enable you to view 2 separate tabs side by side. Only on Desktop.

Oh wow. That's strange. What browser are you using?

Yep. This was a bug. I just fixed it.

Indeed. I think I just fixed this bug.

Good notes indeed. I have just implemented a side by side view so that you can view 2 tabs at once. I hope this helps. Also as other users suggested you can use the notes for saving queries but you can also comment them out in the editor.

Thank you for the suggestions. I have just implemented the following: - Side by Side view to open up two different tabs at the same time - Copy button to copy table names

Thanks for pointing that out. I just fixed the single line comments. It should work as expected now.

Haha. You found a cheat code I guess. I would have to think of hiding the answers from plain sight for the next cases or adding some more rows that include these specific strings.
