Translee : A Real-Time Translator I Built on Gemini Live Translate

Tue, 14 Jul 2026 18:42:19 +0900

I built a browser app that listens to a phone's own speaker and talks back in real time, no delay. It runs on Gemini Live Translate, the streaming translation model Google is rolling out worldwide. Here's what it does and why I built it myself.

My 87-Year-Old Mother Watches Her Granddaughter Grow Up, One Month at a Time

Tue, 07 Jul 2026 08:19:09 +0900

My mother is 87 and lives in the countryside. On a cheap Galaxy tablet, she now scrolls through every month of her granddaughter's life — from birth to today — with no ads, no cloud account, and no monthly fee. Here is the small home-server system that made it possible.

NAS SSH Said 'Connection Refused' — It Was Just the Wrong Wi-Fi

Sat, 20 Jun 2026 00:00:00 +0000

I have two Wi-Fi networks at home. My PC quietly switched to the wrong one. The NAS was fine the whole time.

Nine Apps, 2GB RAM, and the Day It Finally Hit the Limit

Mon, 15 Jun 2026 00:00:00 +0000

For months, nine apps ran on 2GB of RAM without complaint. Then my three-year-old pressed play and nothing happened for ten seconds. A quick diagnosis from Claude Code showed exactly why.

I Built a YouTube Alternative for My Daughter — No Ads, No Algorithm, $0/Month

Fri, 12 Jun 2026 00:00:00 +0000

A 60-year-old dad with no coding background built a private kids' media player on a Synology NAS. No ads, no autoplay rabbit holes, no monthly fee. Here's why — and how.

My Daughter Would Rather Watch Herself Than Baby Shark

Wed, 08 Jul 2026 07:14:34 +0900

I built a private media player so my two-year-old could watch her own baby photos and videos, sorted by month. She now picks it over cartoons and sits with it for an hour. Here is what a no-algorithm, self-hosted archive does that a feed never will.

I Type // Before Any Prompt That Matters. Here's Where It Goes.

Sun, 21 Jun 2026 00:00:00 +0000

My coding history system went through four versions before it stuck. Local files, central files, accidental regression, and finally a NAS folder shared across two PCs.

She Watched Her Own Baby Videos for One Hour. Baby Shark Didn't Stand a Chance.

Wed, 17 Jun 2026 00:00:00 +0000

I added a personal media tab to my home-built kids player — a private gallery of my daughter's growth videos pulled from our NAS backup. What happened next I didn't expect.

Choosing RAM for a NAS That Isn't Officially Supported

Mon, 15 Jun 2026 00:00:00 +0000

The Synology DS224+ spec sheet says 6 GB maximum. Gemini and Claude Code both said buy 8 GB for 10 GB total. I ordered the 8 GB module. Here's how I got there — including a tense few minutes waiting for the NAS to shut down safely.

My Wife's Bible Talks Were Trapped in a Phone Folder. So I Built My First App.

Sat, 13 Jun 2026 00:00:00 +0000

A 60-year-old dad with no coding background built a private audio player for the Bible teachings his wife listens to every morning. It was my first app — put together in a day with AI, running on a home NAS for $0/month.

Two Years of My Daughter's Life Sat Asleep on a Hard Drive

Thu, 09 Jul 2026 02:47:33 +0900

I had about 10,000 photos and videos of my daughter, safely backed up and completely unusable. For two years I meant to sort them and never did. Here's the honest story of the backlog — and why 'backed up' is not the same as 'kept'.

6,000 Files a Year. Finding My Daughter's Face in That Pile.

Thu, 18 Jun 2026 00:00:00 +0000

Phone backup saves memories from loss. But 6,000 mixed files a year isn't a photo album — it's a haystack. Here's the full pipeline I built: auto-backup, a browser picker, a transcoder, and a month grid that finally makes the archive usable.

Installing RAM in My NAS for the First Time in My Life

Tue, 16 Jun 2026 00:00:00 +0000

I paid ₩8,000 extra to avoid a bulk RAM module. It arrived as a bare board wrapped in foil — bulk after all. Then a 60-year-old who had never touched RAM before opened his NAS, labeled the drives, and pushed the module in until it clicked.

In the AI Age, Knowing a Tool Exists Is Most of the Work

Sun, 14 Jun 2026 00:00:00 +0000

These days you don't need to master a technology before you use it. You mostly need to know it exists. A 60-year-old's account of one expert brother, a farm by the Boseong River, and why I keep a notebook of names instead of a shelf of manuals.

The Cutting Board: Never Sort Photos Inside Your Backup Folder

Fri, 10 Jul 2026 04:33:46 +0900

For two years I was stuck sorting my daughter's photos inside the folder that held my only copies. The fix was one idea: copy new files to a disposable 'cutting board' folder, sort there, and never touch the backup. Here's the exact logic — a working folder plus a small ledger — and the prompt that made it click.

My Daughter's Music Stops Mid-Walk. I Spent Hours on It. I Gave Up.

Fri, 19 Jun 2026 00:00:00 +0000

I built a kids music player with no ads and no algorithm. One thing still breaks: continuous playback when the phone screen goes off. Here's what I tried, why it can't be fixed in a web app, and what I do instead.

2 GB vs 10 GB: The Honest Result of My RAM Upgrade

Tue, 16 Jun 2026 00:00:00 +0000

The numbers looked like a triumph: free RAM up 13x, swap from 1 GB to zero, zram from 88% full to empty. The felt improvement for my daughter? About one second. Both are true, and here is why.

Your Old Android Tablet Is a $100 Linux Server (You Just Need Termux)

Mon, 15 Jun 2026 00:00:00 +0000

An ordinary Android tablet — the kind you'd hand a child — can run a real Linux server, quietly, in a living room, on very little power. The catch is that Android isn't Linux. Here's the app that fixes that, and why it isn't in the Play Store.

A Photo Taken at Noon Is on Grandma's Tablet by Dinner

Sun, 12 Jul 2026 08:19:38 +0900

A photo my wife takes at lunch reaches my mother's tablet the same evening — backed up, sorted into the right month, and ready to play. Here's the full near-real-time pipeline, stage by stage, and how long each step actually takes.

A $100 Tablet vs a $293 Laptop: The Math of an Always-On Server

Tue, 16 Jun 2026 00:00:00 +0000

I bought a tablet and a laptop in the same week. Same 128 GB of storage — the tablet cost less than a third as much. For the narrow job of being an always-on home server, a budget tablet holds up well against a 'real' computer. Here are the receipts.

Two Phones, One NAS: Automatic Photo Backup with Synology Drive

Sun, 12 Jul 2026 09:22:52 +0900

My phone and my wife's phone both back up to one home NAS, automatically, with no monthly cloud bill. Here's how the two-phone setup works, why one phone quietly stopped backing up, and how I found and fixed it.

Whisper vs ElevenLabs: When a Recording Has More Than One Voice

Wed, 17 Jun 2026 00:00:00 +0000

My wife wanted to read the Bible teachings, not just hear them. Turning hundreds of hours of audio into text sounds simple — until you notice the recordings have many voices, not one. Here's how I compared Whisper, Naver CLOVA, and ElevenLabs for speaker separation, and what it cost.

The Hourly Check That Quietly Does the Boring Part

Mon, 13 Jul 2026 06:57:10 +0900

Once an hour, a small script copies new phone-backup files onto a working folder so they're ready to sort — and a 'check now' button covers the times I don't want to wait. Here's why automating the boring middle step is what made the whole archive stick.

What Changed When I Made the Recordings Searchable

Thu, 18 Jun 2026 00:00:00 +0000

A pile of audio is a black box: you know he said something about it, but it's buried in hour 50 of hundreds. Transcripts turned that into something you can search — type a phrase, find every place it was said, and jump straight to that moment. Here's how it works, and why it mattered.

A Browser Gallery for Choosing Which Moments to Keep

Mon, 13 Jul 2026 07:20:27 +0900

The one human step in my photo pipeline is choosing which files are actually my daughter. I built a small browser gallery for it — thumbnails, video previews, batch select, jump-to-page — with nothing but Python's standard library. Here's how it works and why I kept it simple.

Why I Built the Same App Twice

Fri, 19 Jun 2026 00:00:00 +0000

I built an audio app for my wife on our home NAS. Then I cloned it onto a tablet for someone else — in an afternoon. You can't do that with Netflix or Spotify. Being able to copy and re-deploy your own software is something rented apps don't give you.

The AI Couldn't Recognize My Own Daughter

Mon, 13 Jul 2026 07:24:24 +0900

I wanted an AI to auto-sort my daughter's photos out of a pile of thousands. I tried face recognition and gave up — a baby's face changes too fast for the model to follow. Here's the honest failure, and why the 'worse' manual approach turned out better.

A Legacy on a Tablet: Giving an 80-Year-Old His Life's Work Back

Sat, 20 Jun 2026 00:00:00 +0000

He is eighty years old, and he gives people their daily bread every morning, asking nothing back. So my wife and I decided to gather everything he's taught, put it on a small tablet, and hand him his own life's work in a box he can hold. This is the heart of the project.

Your Phone Saves H.265. The Browser Wants H.264.

Tue, 14 Jul 2026 07:32:12 +0900

My daughter's videos backed up fine but wouldn't play in the browser — sound, no picture — and the big ones buffered forever. The cause was the video codec (H.265) and the file size. Here's how a one-time ffmpeg conversion to H.264 720p fixed both.

Making an 80-Year-Old the Owner of His Own Server (Domain, Tunnel, and All)

Sat, 20 Jun 2026 00:00:00 +0000

The tablet was in his hands, but the web address it lived at — and the account keeping it reachable — were still mine. A gift isn't truly given until it's owned. So we moved everything into his name. It ended with an 80-year-old pulling out his credit card.

Version 2.0: He Told Me What Was Missing

Sat, 20 Jun 2026 00:00:00 +0000

I thought the legacy was finished. Then, at the very moment I handed it over, the eighty-year-old told me what was missing — teachings we didn't have. So the tablet came back to my desk for one more round. It goes back to him this Sunday. This is how personal software is never quite done.

The Time the AI Gave Me Five Different Answers

Sun, 21 Jun 2026 00:00:00 +0000

I save every prompt I type. Going back through one log, I found a session worth sharing — the AI gave me five different answers to one simple question, and what finally got it right wasn't a better prompt but something the AI couldn't know.

The AI Kept 'Fixing' Words That Were Already Right

Mon, 22 Jun 2026 00:00:00 +0000

AI transcription leaves errors, so I asked a smart model to clean them up. It confidently 'corrected' a name that was already spelled right — and the deeper trap was that the same name is spelled two different ways in the source, depending on the book. Here's how I made the model follow a source of truth instead of its own memory.

The Bug That Put Every Search Result 20 Minutes Off

Tue, 23 Jun 2026 00:00:00 +0000

My audio search worked — except it sometimes dropped you into the recording twenty minutes before the word you searched for. The cause was one piece of data quietly doing two jobs at once. Here's the diagnosis, the fix, and why it had been quietly burning my API budget.

One Engine, Many Apps: Why My Second App Was Nearly Free

Thu, 02 Jul 2026 03:16:04 +0900

I built one engine — take in recordings, transcribe them, make them searchable, play them back at the exact moment. Then a second speaker needed the same thing. Then that content turned out to be video, not audio. Neither was a rebuild. Here's how building your own software adds up.

Fire and Forget: Running Hundreds of Paid AI Jobs Without Wasting Money

Thu, 02 Jul 2026 03:16:05 +0900

I had to push hundreds of recordings through paid AI APIs from a home PC. Three things will hurt you: runaway cost, a crash halfway through, and babysitting the job for hours. Here are the plain patterns — resumable reruns, hard cost ceilings, real progress output — that let me start a job and walk away.

I Fixed the Bug. My Phone Kept Showing It Anyway. (The Caching Trap)

Tue, 07 Jul 2026 07:26:01 +0900

You fix something, upload it, open the app on your phone — and the bug is still there. So you fix it again. The fix was right all along; the culprit is caching. Here's why your changes don't show up, the layers where old copies hide, and why 'clear the cache' is only a band-aid.

A Server for an 80-Year-Old Who Can't Fix It: How It Survives Without Me

Tue, 07 Jul 2026 07:29:40 +0900

I gave a home server to an eighty-year-old who can't troubleshoot anything. So it had to survive on its own: power cuts, network changes, a dead battery. Here are the three things that make a small server fix itself — auto-restart on boot, reachable on any Wi-Fi, and battery protection.

Claude Code Login didn't work on my second PC. This is what finally helped me.

Tue, 07 Jul 2026 15:46:40 +0900

Moving Claude Code to a second PC with the same Pro subscription triggered a 401 error I couldn't shake. I tried everything the internet suggested. None of it worked. Here's what did.

I Typed "Still First Page" Fourteen Times

Wed, 17 Jun 2026 00:00:00 +0000

Adding one feature to my photo picker tool took ninety minutes and fourteen failed attempts. Here's what kept going wrong.

Three Ways to Access Your Synology NAS — and the Fix When Explorer Stops Working

Tue, 16 Jun 2026 00:00:00 +0000

I keep forgetting how to reconnect my NAS in Windows Explorer. Today it didn't just disappear — it refused to connect even on the same Wi-Fi. A corrupt wireless driver was the reason. Here is what worked.

The Scanning Company Said Cut the Spine. So I Used My Phone.

Mon, 15 Jun 2026 00:00:00 +0000

A rare 1974 German theology book. A scanning company that wanted to cut the binding. A phone camera. And Claude Code to build the pipeline that turned 111 photos into a 220-page Korean PDF — with automated paragraph validation and a total Gemini API cost of about 18,000 KRW.
