Hey all,

Just wanted to share a little project I’ve been working on called Nomad, it’s a tiny, fully offline media server built around the ESP32-S3. The entire thing fits in your pocket (literally USB thumb drive-sized), costs around $30, and serves up a web interface for watching videos, reading books, and listening to music over local Wi-Fi, no internet needed.

You just flash the ESP32, drop your media onto a FAT32 SD card (even if its over 32gb, check the docs), and power it via USB. When powered, it spins up a captive Wi-Fi portal that works like in-flight entertainment systems. It streams .mp4, .mp3, .pdf, etc, and supports multiple simultaneous users. A 64GB card holds around 50 movies, a handful of shows, and 100s of pdf books / audio files.

I built it originally because I was road-tripping a lot and wanted something like my Jellyfin server, but lighter, smaller, and way more portable than the typical homelab gear. I posted it to r/homelab where it got a great reception, but I figured this community might also appreciate the completely self-hosted and air-gapped aspect.

It’s super WIP, more features like USB file upload, GPS maps, and HTML5 games are planned.

Would love feedback, feature suggestions, or just to see if anyone else is into tiny self-hosted stuff like this. Happy to answer questions too!

Started this journey 2 years ago. Proud of what I've been able to accomplish so far :)

Hey everyone,

I’d like to share a tool I developed for my personal use because I couldn’t find any open source solution that lets me centrally archive and backup my IMAP mailboxes and, importantly, search across all of them at once.

What does Mail-Archiver do?

It automatically archives incoming and outgoing emails from multiple IMAP accounts into a local PostgreSQL database. This allows me to:

• Store emails and attachments,
• Search across all archived mailboxes with filters like date range, sender, recipient, and more,
• Export individual emails (EML) or bulk export
• Restore selected emails or entire mailboxes back to a target mailbox if needed.

This helps me keep my inboxes clean while having full offline access to all my emails without relying on any provider. There’s also a handy dashboard with statistics and storage monitoring.

Why am I sharing this?

I found there’s a real lack of solid turnkey selfhosted solutions for centralized mail archiving with search capabilities. So if you’re juggling multiple IMAP accounts and you are looking for a way to back up and search your emails in one place, this might be useful to you.

Contributions, feedback, or feature requests are very welcome!

Hey folks,

I recently built a macOS app called Wallper - it lets you set 4K animated wallpapers on your desktop.
I made it for myself at first, because I couldn’t find a good alternative to Wallpaper Engine on Mac.

It’s completely native, open-source, runs fully locally - no account, no login, no telemetry.
There’s an online library built-in, but it’s optional, you can just drop your own videos and go.

Main features:

– 600+ 4K animated wallpapers
– Local-only by default
– Open-source (Swift)
– Optional community library
– No background tracking or online accounts
– Add your own private videos (device-only, not shared)

Built this because I missed having something visual and customizable that didn’t feel bloated or invasive.

Would love to hear what you think.

Thanks!

One cert manager to rule them all, one CA to find them, one browser to bring them all, and in encryption bind them.

So after a month of tapping away at the keys, I’m finally ready to show the world SphereSSL(again).

Last month I released the Console test for anyone that would find it useful while I build the main version.
The console app was not met with the a warm welcome a free tool should have received. However undiscouraged I am here to announce SphereSSL v1.0, packed with all the same features you expect from ACME with a responsive simple to use UI, no limits or paywalls. Just Certs now, certs tomorrow and auto certs in 60 days.

This isn’t some VC-funded SaaS trap. It’s a 100% free, open-source (BSL 1.1 for now) SSL certificate manager and automation platform that I built for actual humans—whether you’re running a home lab, a small business, or just sick of paying for something that should’ve been easy and free in the first place.

What it does

• Automates SSL certificate creation and renewal with Let’s Encrypt and other ACME providers (supporting 14 DNS APIs out of the box).
• Works locally or for public domains—DNS-01, HTTP-01, manual, even self-signed.
• Handles multi-domain SAN certs, including assigning different DNS providers for each domain if you want.
• Cross-platform: Native Windows tray app now, Linux tray version in the works (the backend runs anywhere ASP.NET Core does).
• Convert and export certs: PEM, PFX, CRT, KEY, whatever. Drag-and-drop, convert, export—done.

Why?

Because every “free” or “simple” SSL tool I tried either:

• Spammed you with ads, upcharges, or required a million steps,
• Broke on anything except the exact scenario they were built for,
• Or just assumed you’d be fine running random scripts as root.

I wanted something I could actually trust to automate certs for all my random servers and dev projects—without vendor lock-in, paywalls, or giving my DNS keys to a third party.

What’s different?

• You control your keys and DNS. The app runs on your machine, and you can add your own API credentials.
• Modern, functional UI. (Not a terminal app, not another inscrutable config file—just a web dashboard and a tray icon.)
• Not a half-baked script: Full renewal automation, error handling, status dashboard, API key management, cert status tracking, and detailed logs.
• Source code is public. All of it: https://github.com/SphereNetwork/SphereSSL

Dashboard:

SphereSSL Dashboard. Create certs, View Certs

Verify Challenge:

Live updates on the whole verification process.

Manage:

Manage Certs, Toggle Auto Renew, Renew now, or Revoke a cert.

Release: SphereSSL v1.0

License

• Open source (Business Source License 1.1). Non-commercial use is free, forever. If you want to use it commercially, you can ask.

Features / Roadmap

• 14 DNS providers and counting (Cloudflare, Namecheap, GoDaddy, etc.)
• Multi-user support, roles, and API key management
• Local and remote install (use it just for your own stuff, or let your team manage all the certs in one place)
• Coming soon: Linux tray app, native installers, more CA support, multi-provider order support, webhooks, and direct IIS integration

Who am I?

Just a solo dev who got tired of SSL being a pain in the ass or locked behind paywalls. I built this for my own projects, and I’m sharing it in case it saves you some time or headaches too.
It’s meant to be easy enough for anyone to use—even if you’re inexperienced—but without losing the features and flexibility power users expect.

Feedback, issues, PRs, and honest opinions all welcome. If you find a bug, call it out. If you think it’s missing something, let me know. I want this to be the last SSL manager I ever need to build.

if you don't know, OliveTin is a UI for executing shell commands with button presses and (although I'm still learning it) it's really great.

https://preview.redd.it/a6wvm8s1fqbf1.png?width=2354&format=png&auto=webp&s=34b783a99e5813a343163d1685f70f094b627766

e.g. I have two Pi-Hole instances and from time to time I want to disable ad blocking and it was a bit of a faff to disable both of them. But you can see from my screenshot there I have two buttons that disable pi-hole (for 5 / 10 / 15 mins) or enable them again with a click. That's great and much more convenient, but you still have to load up the OliveTin UI and click the buttons etc and I was wondering if I could do it more easily from my phone.

Enter Macrodroid (android device automation app). I was messing around with this and only just realised you can create quick tiles, and you can use OliveTin's API to trigger actions from a third party service, like Macrodroid. You create the macro that executes an action in OliveTin, and trigger it using a quick tile (or voice command, or nfc tag, or shortcut or geofence or whatever other trigger you want to use). So as you can see here, I can now disable two pi-hole instance for 5 mins with a quick press on my phone's quick tiles. Or restart my calibre container (which i have to do now and again because we live in hell)

This is fantastic, but i had a search and no one ever seems to have mentioned it? Is it something really obvious that everyone's already doing.. and it's so mundane that it's not even worth mentioning? Why have a web UI and button presses to execute commands when you could restart your jellyfin container by tapping your phone on an NFC tag stuck to the fridge or whatever.

If I am late to this, I feel really dumb tbh. You could have told me earlier.

Happy dashboard Wednesday - been looking here for a while getting inspiration from you all, and I'm finally happy with my Homepage and how it turned out. Been homelabbing for about 5 years now, and have spun up my fair share of services in that time. Let me know what you all think!

I have created a Raid 5 Storage with 3 hdds and while installing a new GPU I aciddentaly disconected a HDD. After starting the server ZimaOS told me its read only because a hdd disconnected. I turned of the Server and reconnected the HDD. The Raid is no longer read only but when i try to install Jellyfin with my Media on the Raid it tells me its read only, but i can make folders and files on the Raid. Can someone please help me?

Edit: ZimaOS also doesn't say the Raid is Read only in Storage Settings page
