How I Repurposed My Daughter's Old Tablet Into a Macro Pad

 

My Daughter's Tablet Was Collecting Dust.

WHERE IT STARTED

I bought an Amazon Fire 7 Kids tablet in November 2022. It did exactly what it was supposed to do — durable, controlled, something a kid could actually use without destroying. My daughter used it for years. Then she grew up, the tablet got more boring than what she needed, and somewhere along the way it ended up in a drawer, covered in dust, completely dead.

I found it months later and figured it was done. Plugged in a charger anyway. It turned on. Fully functional. I paid $55 for it in 2022. My daughter used it for two years. And now it runs my entire desk.

I Wanted a Macro Pad. I Didn't Want to Buy One Blind.

THE PROBLEM

From November 2025 I'd been researching how to add more ergonomics to my desk setup. The PC came together fully at the end of February. But coming from the Lenovo Legion that burned out, I wanted more control over the functions I use constantly. A macro pad made sense.

The problem: I don't buy things without knowing they'll actually work in my day-to-day. A dedicated macro pad is a commitment — hardware, software, learning curve. If it doesn't fit the workflow, it just becomes another thing on the desk.

Then I found MacroDeck. Open source. No account. No subscription. You install the server on the PC and the client on any Android device. That's it.

Open Source. No Subscription. No Account Required.

THE SOLUTION

MacroDeck caught my attention for one specific reason: open source, no account, no subscription. No cloud dependency, no monthly fee, no login wall. Install the server on the PC, install the client on any Android device, connect. Done.

I decided to use the Fire 7 that was already sitting on my desk. Wiped the Amazon account, disabled everything I could, installed MacroDeck. It connected immediately.

The Network — Again.

THE FIRST PROBLEM

MacroDeck connects to the PC by IP address. Which means if the PC's IP changes, MacroDeck loses the connection. Every time. While OPNsense was running, DHCP static mapping handled this automatically — the PC always had the same IP. When OPNsense went down, the problem came back.

The fix was the same one I used for Moonlight: manual static IP in Windows IPv4 settings. Set it once, leave it. MacroDeck finds the PC instantly every time.

Not Plug and Play. But Close.

THE CONFIGURATION

The install was straightforward. The configuration wasn't always. Some commands and integrations didn't work on the first try — or the second. Getting the buttons to do exactly what I needed required reading, testing, and some trial and error.

What made it worth it: MacroDeck lets you segment commands by application. Different buttons for different contexts — design work, gaming, system controls. The tablet knows what you're doing and shows you the relevant controls.

I added custom icons I designed myself. No default icon packs, no RGB, no unnecessary visual noise. Just a screen that shows exactly what I need, when I need it.

The main screen handles the essentials: direct app launchers for Photoshop, Illustrator, CapCut, and 3DS Max, live GPU and CPU temperature monitoring, a one-tap hibernate button, and volume controls with the current level visible at a glance.

Each application gets its own subfolder with context-specific commands. The Illustrator page covers the operations I repeat constantly — same color selection, stroke weight, case changes, compound release, expand appearance. Things that were buried in menus now have a dedicated button.

The 3DS Max page solves a specific daily frustration: switching units. Millimeters, meters, centimeters, feet, inches — one tap each. No more digging through settings mid-model.

One limitation worth knowing: the main screen dictates the grid size for the entire setup — and every subfolder inherits that same grid. You can't have a 4×3 main screen and a 2×2 subfolder. Everything follows the same layout. I haven't fully settled on my ideal grid yet. Think about your grid size before you start building — changing it later means reorganizing everything.

One Screen. Everything I Touch Daily.

HOW I ACTUALLY USE IT

The commands I use most are mapped and accessible in one tap. App launchers, system shortcuts, temperature monitoring, media controls. Things I was doing with keyboard shortcuts or mouse clicks that now have a dedicated button on a screen I can glance at without moving my hand.

The detail that surprised me most: it works perfectly with Moonlight. When a remote gaming session on the TUOHAITIME tablet ends, I hibernate the PC directly from MacroDeck on the Fire 7. One tap from the desk surface. Done. I don't need to walk to the office or switch to the keyboard.



$0 Extra. One Tablet. One Afternoon.

WHAT IT TOOK

The Fire 7 was already paid for years ago. MacroDeck is free. The only investment was the time to configure it properly — and the patience to fight through the commands that didn't work on the first try.

If you have an old Android tablet collecting dust, this is the best use I've found for one.

What's Next.

THE ROADMAP

  • OPNsense back online — DHCP static mapping returns, MacroDeck gets more stable
  • Expanding the command library as the workflow evolves
  • Custom designed icon pack — full set, consistent style

If you have an old tablet sitting in a drawer, don't sell it. Don't throw it out. Give it a job.

From Fear to Control: What Self-Hosting Gave Me

From Fear to Control: What Self-Hosting Gave Me A DIFFERENT KIND OF POST I'll confess something. When I first started experimenting with self-hosted services, it wasn't because I wanted a cool homelab. It wasn't because I wanted to play with Docker, firewalls, VLANs, or enterprise-grade networking. It started from something much simpler. Need. And fear. I had old equipment sitting around collecting dust. Hardware that technically still worked, but had no purpose anymore. At the same time, I felt an increasing need for something I couldn't fully get from consumer-grade solutions: control. I wanted more security. I wanted more visibility. Most importantly, I wanted to better protect my children. That was the real beginning. Like many parents, I tried the usual tools first. I explored what Google Family Link offered. I tried the parental controls built into Microsoft Windows Family Safety. I tested schedules, device restrictions, app limits, and whatever...

When One Problem Turns Into Two

When One Problem Turns Into Two The calm before... This post contains Amazon affiliate links. If you purchase through them, I may earn a small commission at no extra cost to you. Every product mentioned here is something I personally own and use. I'd enjoyed almost a month of absolute peace. My OPNsense firewall was working flawlessly, without a single outage. It was performing so well that, to be honest, I'd fallen into that dangerous state of complacency where you don't even check the logs or the connection. You simply assume everything will be fine forever. Until this morning. At 7:01 AM, I sat down at my computer ready to start the workday and was met with the worst possible screen: No connection. At first, nothing made sense. The infrastructure had been stable for weeks. The OptiPlex running OPNsense was powered on. The NUC was powered on. Physical links? At first glance, all good. Ever...

Google Photos Was Free. Until It Wasn't. Here's My Setup Now.

I Trusted Google With Ten Years of Memories. Then the Rules Changed. The problem... The problem... Photography has always been one of my favorite hobbies. Not professionally — I never went that route. But personally, I've taken photos of everything that matters to me: family moments, projects, travel, random memories, everyday life. Back in 2015, I discovered Google Photos. Honestly, it felt revolutionary. Before that, managing photos was a mess — my phone constantly filled up, I had to manually copy everything to external hard drives, and I ended up with four or five different drives scattered everywhere. Finding a specific photo from years ago meant remembering which drive had it, connecting it, and hoping I'd organized things correctly. Google Photos changed all of that. Every photo available instantly from anywhere. Search by face, color, event, date, location, objects inside the image. If I wanted photos of my wife, I could simply search for her face. At the time, it felt ...
