Raspberry Pi projects to try this weekend (March 20


It’s that time of the week again—the time when the week ends and the weekend begins! That means you’ll have a few days to tinker with that Raspberry Pi that’s been sitting in a drawer for far too long, so why not give HomeBox, ntfy, or ChangeDetection.io a try?

Cortex-A72 (ARM v8)

With the Raspberry Pi 4 Model B, you can create all kinds of fun projects, and upgrade gadgets around your home. Alternatively, install a full desktop OS and use it like a regular computer.


Keep tabs on your home’s inventory with HomeBox

A solid home inventory has a multitude of users

I’ve kicked around the idea of starting a proper home inventory for years. In fact, several years ago, I started the process by using an app called Sortly to document my Funko! POP collection.

I stopped using Sortly because it got expensive to use, and just never really worried about home inventory after that. HomeBox, however, is different.

As a completely self-hosted solution, HomeBox gives you a full home inventory system without having to spend a dime. You’re able to use HomeBox to define items, log what an item’s value is, add extra details, and a lot more. The multi-user mode of HomeBox makes it ideal for a multi-person household—with each user only seeing the items that belong to them (unless they’re an admin).

If you haven’t considered building out a home inventory, let this be a sign to start thinking about it. Not only is it a good thing to have to just know where an item is, but it could also be invaluable if you ever have to make an insurance claim as you’ll have the documentation of what was in your home, its value, and what was lost.

Build your own push notification server with ntfy

Your homelab is running tasks all the time, but is it letting you know?

Have you ever wanted to get a push notification when something happened in your homelab, but didn’t want to set up Discord or Telegram notifications? Then ntfy (pronounced notify) is the perfect piece of self-hosted software to put on your Raspberry Pi.

Simply allow notifications from the ntfy website or install the ntfy app on your iPhone or Android, and then you’re ready to start configuring notifications within your homelab.

It’s simple, ntfy works by sending PUT or POST HTTP requests and even works with a REST API. You can integrate ntfy into just about any area of your homelab, like getting alerts for when a backup completes or fails, when a download finishes, when a cron job runs, or anything else you can think of.

A Raspberry Pi makes the perfect home for ntfy because it’s a lightweight program that can even run on a Pi Zero 2 W with ease. If you haven’t deployed your own push notification stack yet, it’s time to take that step.

Quad-core 64-bit ARM Cortex-A53

The Raspberry Pi Zero 2 W is super tiny and super affordable, but it packs enough computing power for a variety of DIY projects. You can use it to create a handheld retro gaming console, for Klipper/Mainsail, a super compact home or media server, and more. 


Know when webpages are changed with ChangeDetection.io

Price drops, restocking alerts, and more

If you’ve ever wanted to know when a website changed, then ChangeDetection.io is perfect for you. Designed as a self-hosted piece of software that runs on your Raspberry Pi, ChangeDetection.io allows you to watch any webpage and get notified if something changes.

This could be having it watch a product page like a hawk to see when the price drops (or when an out-of-stock item goes back in stock). It could also be used to monitor your competitor’s pages to know when they update. Or, even just looking at specific text or elements to be updated.

The sky’s really the limit here. The way ChangeDetection.io works is you add the URL, and it does an initial crawl of the website. Then, it periodically does another crawl to see if the content matches. If it does, nothing more happens but another scheduled crawl. If the content does change, however, it sends you an alert to let you know so you can dive deeper into what’s different.

ChangeDetection.io is a piece of software that either will often be used by you or not, but it’s hard to know without at least trying it out first. So, deploy ChangeDetection.io on your Pi and see how useful it is in your everyday workflow.


You don’t have to have the latest Pi to self-host services

If you’re sitting there, thinking that you need the latest Raspberry Pi 5 to self-host any of these services—think again. I have a Pi 3 B and two Pi 4 B’s, and they both handle self-hosted services almost identically.

Sure, some more resource-intensive apps, like Plex or Ollama, would run better on a beefier Pi 5, but you definitely don’t need a Pi 5 to run traditional self-hosted programs like I’ve featured above. Dig that old Pi 3 B out of storage, install the latest Raspberry Pi OS, and get started on your self-hosting journey today.

Do you ever walk past a person on the streets exhibiting mental health issues and wonder what happened to their family? I have a brother—or at least, I used to. I worry about where he is and hope he is safe. He hasn’t taken my call since 2014.

When I was 13, I had a very bad day. I was in the back of the car, and what I remember most was the world-crushing sound violently panging off every surface: he was pounding his fists into the steering wheel, and I worried it would break apart. He was screaming at me and my mother, and I remember the web of saliva and tears hanging over his mouth. His eyes were red, and I knew this day would change everything between us. My brother was sick.

Nearly 20 years later, I still have trouble thinking about him. By the time we realized he was mentally ill, he was no longer a minor. The police brought him to a facility for the standard 72-hour hold, where he was diagnosed with paranoid delusional schizophrenia. Concluding he was not a danger to himself or others, they released him.

There was only one problem: at 18, my brother told the facility he was not related to us and that we were imposters. When they let him out, he refused to come home.

My parents sought help and even arranged for medication, but he didn’t take it. Before long, he disappeared.

My brother’s decline and disappearance had nothing to do with the common narratives about drug use or criminal behavior. He was sick. By the time my family discovered his condition, he was already 18 and legally independent from our custody.

The last time he let me visit, I asked about his bed. I remember seeing his dirty mattress on the floor beside broken glass and garbage. I also asked about the laptop my parents had gifted him just a year earlier. He needed the money, he said—and he had maxed out my parents’ credit card.

In secret from my parents, I gave him all the cash I had saved. I just wanted him to be alright.

My parents and I tried texting and calling him; there was no response except the occasional text every few weeks. But weeks turned into months.

Before long, I was graduating from high school. I begged him to come. When I looked in the bleachers, he was nowhere to be seen. I couldn’t help but wonder what I had done wrong.

The last time I heard from him was over the phone in 2014. I tried to tell him about our parents and how much we all missed him. I asked him to be my brother again, but he cut me off, saying he was never my brother. After a pause, he admitted we could be friends. Making the toughest call of my life, I told him he was my brother—and if he ever remembers that, I’ll be there, ready for him to come back.

I’m now 32 years old. I often wonder how different our lives would have been if he had been diagnosed as a minor and received appropriate care. The laws in place do not help families in my situation.

My brother has no social media, and we suspect he traded his phone several years ago. My family has hired private investigators over the years, who have also worked with local police to try to track him down.

One private investigator’s report indicated an artist befriended my brother many years ago. When my mother tried contacting the artist, they said whatever happened between them was best left in the past and declined to respond. My mom had wanted to wish my brother a happy 30th birthday.

My brother grew up in a safe, middle-class home with two parents. He had no history of drug use or criminal record. He loved collecting vintage basketball cards, eating mint chocolate chip ice cream, and listening to Motown music. To my parents, there was no smoking gun indicating he needed help before it was too late.

The next time you think about a person screaming outside on the street, picture their families. We need policies and services that allow families to locate and support their loved ones living with mental illness, and stronger protections to ensure that individuals leaving facilities can transition into stable care. Current laws, including age-based consent rules, the limits of 72-hour holds, and the lack of step-down or supported housing options, leave too many families without resources when a serious diagnosis occurs.

Governments and lawmakers need to do better for people like my brother. As someone who thinks about him every day, I can tell you the burden is too heavy to carry alone.
