Raspberry Pi Projects: The Complete 2026 Guide

The Raspberry Pi turned fifteen in 2027, but 2026 is when the community genuinely started asking hard questions about it. Cheap x86 mini PCs from brands like Beelink and CWWK now sell for $150–$200 CAD, NVMe-equipped and running full Windows or Ubuntu out of the box. ESP32 boards handle low-power sensor work for a few dollars. Squeezed from both sides, the Pi should probably be dead. It is not.

What the Pi owns in 2026 is a specific, well-defined middle ground: single-board Linux in a 5W power envelope with a massive community behind it, GPIO pins for hardware projects, and a price point that makes failure cheap. For always-on home services, guitar amp modeling, local smart home control, and low-stakes learning projects, there is still no better tool for the job. Where the Pi struggles — database-heavy workloads, transcoding, anything that needs fast NVMe storage — a mini PC wins, and you should just use a mini PC. This guide walks through every major Pi project category, the hardware decisions that actually matter, and the cases where you should walk away.

Picking Your Pi

Pi 5 vs Pi 4: Which One Should You Actually Buy?

The Pi 5 launched in late 2023 and by 2026 has settled into a clear premium tier. The quad-core Cortex-A76 runs roughly 2–3x faster than the Pi 4’s Cortex-A72 on CPU-bound workloads, and it finally ships with a PCIe 2.0 interface that unlocks NVMe storage via an M.2 HAT. If you are buying new today, the Pi 5 4GB is the default recommendation for most projects.

That said, the Pi 4 is not irrelevant. A Pi 4 4GB or 8GB still handles Pi-hole, Home Assistant, and light self-hosting fine, and used units have dropped to $40–$60 CAD. For real-time audio work specifically, the CPU gap matters: if you are running neural amp modeling, our head-to-head comparison of Raspberry Pi 5 vs Pi 4 for Neural Amp Modeler found that the Pi 4 at 128-sample buffers hits sustained CPU usage that produces occasional dropouts under load, while the Pi 5 handles the same models cleanly. For everything else, either board works.

Pi vs Mini PC: Knowing Where the Line Is

This comparison comes up constantly, and the honest answer is context-dependent. We ran a full Raspberry Pi 5 vs Mini PC home server comparison covering power consumption, storage throughput, and total cost of ownership over three years. The Pi 5 wins decisively on idle power (around 3–5W vs 10–15W for a mini PC) and it wins on price when you already own one. The mini PC wins on raw throughput, NVMe read speeds, and any workload that benefits from faster storage.

If that is still not enough to decide, one of our editors spent eight months running a mini PC for home services and then switched back to a Pi. His honest write-up on why he returned to the Pi 5 after eight months on a mini PC covers the real-world reasons: power bills matter in Canada, and the Pi’s thermal behaviour in an always-on enclosure is more predictable than budget mini PC fan curves at 3 AM.

Always-On Services

Raspberry Pi 5 as a Home Server

The Pi 5 with an NVMe HAT and a 256GB or 512GB M.2 drive is a genuinely capable home server for 2026. Running services like Nextcloud, Vaultwarden, Gitea, or Jellyfin (for low-bitrate streams) is well within reach. The practical ceiling is concurrent users and 4K transcoding — both will push the Pi past its comfort zone. For a single-household setup where one person at a time is pulling files or running containers, it holds up.

The broader question of when self-hosting makes sense is worth reading carefully before you invest time. Our guide on self-hosting on a Raspberry Pi 5 — when it works and when it does not is the most honest take we have published on this. The short version: if you need reliability above 99% or if your workload is storage-intensive, the Pi is the wrong tool. If you want to learn self-hosting, reduce cloud dependency, or run lightweight services for a household, it is excellent.

Pi-Hole and Network Ad Blocking

Pi-hole remains one of the most popular reasons people buy a Pi in 2026, and it is still a genuinely good use case. The entire stack runs comfortably on a Pi Zero 2W or a spare Pi 3, and the power draw is negligible. Install takes about twenty minutes. The practical benefits — network-wide ad blocking across every device including smart TVs and IoT gadgets — are real and immediately noticeable.

Setup has gotten simpler over the past two years, and Pi-hole v6 ships with a cleaner dashboard and better upstream resolver handling. Pair it with Unbound for recursive DNS and you have removed one more dependency on third-party resolvers.

Home Assistant and Local Smart Home Control

For Canadians who have been burned by cloud smart home platforms shutting down or degrading service, running Home Assistant on a Pi 5 is a compelling alternative. The platform handles Zigbee, Z-Wave, Thread, and Matter locally, with no cloud dependency once it is set up.

The trigger for a lot of Home Assistant migrations in 2026 has been Amazon’s rollback of some Alexa smart home integrations. Our post on what Amazon’s smart home changes mean for Raspberry Pi 5 and Home Assistant users covers exactly what shifted and the recommended hardware path for people making the switch. The Pi 5 4GB handles a full Home Assistant OS install with fifty or more devices without breaking a sweat.

Audio and Creative Projects

Turning a Pi Into a Real-Time Guitar Amp Modeler

This is the most technically impressive Pi project category in 2026, and also the one with the steepest learning curve. Neural amp modeling — running trained neural networks that capture the character of specific amplifiers in real time — is now viable on a Pi 5, with latency low enough to be playable when configured correctly.

The starting point is our original walkthrough on how to turn a Raspberry Pi into a real-time guitar amp modeler, which covers the full software setup from scratch. For newcomers deciding whether to commit, the sub-$250 CAD guitar amp modeler rig shopping guide lays out a complete parts list with honest tradeoffs at each price point.

NAM vs GuitarML vs Aida-X: Which Software Should You Use?

There are now three mature neural amp modeling applications that run on Pi hardware, and they are meaningfully different. NAM (Neural Amp Modeler) has the largest model library and is the community default. GuitarML’s Proteus and Smart Amp plugins offer a different capture approach. Aida-X is the most recent entry with strong tone quality on limited hardware.

We ran all three on a Pi 5 with identical conditions. The full NAM vs GuitarML vs Aida-X latency and quality test on Raspberry Pi 5 is the most thorough comparison available for this use case. If you want the short version: NAM wins on model selection, Aida-X wins on CPU efficiency at equivalent quality, and GuitarML is the easiest to get running for beginners.

Choosing a USB Audio Interface

The audio interface is the most consequential single hardware decision in any Pi guitar rig. A bad interface introduces latency or noise that no software can fix. The Pi’s onboard audio is not usable for real-time instrument input — you need USB.

The 2026 buyer’s guide to USB audio interfaces for Raspberry Pi guitar rigs covers the Focusrite Scarlett Solo 4th Gen, the 2i2, the Behringer UCA222, the UMC22, and a handful of others with confirmed Pi compatibility. The Behringer UCA222 at roughly $25 CAD is the budget recommendation if you are not sure the project will stick. The Scarlett Solo is the upgrade path once you are committed — cleaner preamp, lower round-trip latency.

Voice Assistant and Bonnet Projects

Local voice assistants on Pi hardware had a rough 2024 when driver support for the Google AIY Voice Bonnet broke under newer Raspberry Pi OS builds. Community developers worked through the kernel driver issues and the bonnet is back in working order for Raspberry Pi OS Trixie. Our full guide on how the updated Voice Bonnet works again on Raspberry Pi Trixie covers what changed, why it broke, and the setup steps to get it running cleanly in 2026.

Pi HATs and Accessories

Multi-Protocol HATs: RTL-SDR, LoRa, GPS, and RTC

HATs that stack multiple radio protocols on a single board sound appealing in theory — one add-on for SDR, LoRa mesh, GPS, and real-time clock functions. The reality is that multi-protocol HATs involve real engineering tradeoffs around RF interference, power delivery, and driver support that single-protocol boards sidestep entirely.

We tested five of the most-discussed multi-protocol HATs in 2026 and the results were genuinely mixed. The detailed RTL-SDR LoRa GPS RTC HAT comparison covers performance, setup difficulty, and the use cases where each board makes sense. The short takeaway: if you need SDR for one application and LoRa for another, separate dedicated boards almost always outperform the combined option.

Pi Gaming and Retro Console Projects

The Pi 5’s increased CPU horsepower has made Sega Saturn and Nintendo 64 emulation genuinely viable via Recalbox V10, which was barely workable on Pi 4 hardware. Our step-by-step beginner guide to building a PI64 retro gaming console walks through the full process from Recalbox flashing to controller pairing.

The one part of retro gaming builds that consistently trips people up is controller selection. Not all Bluetooth gamepads work reliably in Recalbox — pairing works but input lag or dropped connections appear under load. The 7 best Bluetooth controllers for Raspberry Pi gaming in 2026 is based on real compatibility testing, not spec sheets.

Novelty and Creative Hardware Projects

Not every Pi project is about productivity. The Lego Game Boy mod using a Raspberry Pi Zero that circulated on r/raspberry_pi earlier this year is one of the more charming builds we have covered — a fully functional handheld console in a Lego shell for under $55 USD. The TinyProgrammer autonomous Pi project that writes Python code at human speed, connects to a retro BBS, and shuts itself down at night is the kind of project that reminds you why the community exists.

For families, the DIY home calendar system built on a Pi 3 wall display with live weather and Google Calendar integration is a great Saturday project. And if you are buying for a young learner, our 5 best Raspberry Pi starter kits for young tech enthusiasts covers the CanaKit Pi 5, the Raspberry Pi 400, and three other bundles we actually recommend. There is also a solid case for building a distraction-free Pi Zero 2W writing device for kids — no internet, no games, just a keyboard and a text editor, for under $100.

When NOT to Use a Pi

This deserves its own section because the Pi gets recommended reflexively in places where a different tool is clearly better.

Do not use a Pi for Plex or Jellyfin if you are transcoding 4K content for more than one stream. The Pi 5 has no hardware H.264/H.265 transcoding in the way a modern mini PC GPU does. You will hit 100% CPU and dropped frames.

Do not use a Pi as a primary router if your household is running more than 150 Mbps symmetrical throughput. Pi-hole on a Pi is great; pfSense on a Pi is not. The USB ethernet adapter path adds latency and the Pi’s CPU becomes the bottleneck under real traffic.

Do not use a Pi for anything that needs NVMe-class storage throughput. Even with an M.2 HAT, the PCIe 2.0 x1 interface tops out around 500 MB/s under ideal conditions. A $150 CAD mini PC with a proper M.2 slot will do the same job faster and more reliably.

The community’s own honest self-assessment is worth reading: our most-commented post of 2026 was about whether there are fewer and fewer use cases for the Raspberry Pi, written by a home labber who decommissioned his last Pi. His argument is better than you expect — and his conclusion is more balanced than the title suggests.

Frequently Asked Questions

Is the Raspberry Pi 5 worth buying in 2026?

Yes, with context. If you are building a new always-on home service (Pi-hole, Home Assistant, Nextcloud), the Pi 5 4GB is the right board. The CPU improvement over Pi 4 is meaningful for multi-service setups, and the PCIe interface finally makes fast storage practical. If you have a Pi 4 already running stable services, upgrading is not urgent. If you need raw storage or compute performance, a mini PC is the more honest recommendation.

Can a Raspberry Pi replace a NAS or home server?

For a single-person or couple household with light storage needs — file sync, password manager, a few containers — yes, a Pi 5 with an NVMe HAT handles it. For a family with 4K media, multi-user access, and high-availability requirements, no. The full breakdown is in our self-hosting on Pi 5 guide.

What is the best first Raspberry Pi project for a beginner?

Pi-hole is the most reliable recommendation: low setup time, immediate practical benefit, and almost nothing can go wrong permanently. The DIY family calendar display is a close second for households that want a visible, shareable result. For anyone interested in music, the introductory guitar amp modeler guide is approachable even without prior Linux experience, as long as you are prepared to spend an afternoon on it.

How does the Raspberry Pi hold up against cheap mini PCs for always-on home use?

The Pi’s advantages are power consumption (3–5W vs 10–15W idle), form factor, and community support depth. The mini PC’s advantages are storage speed, raw compute, and Windows compatibility for workloads that need it. For always-on services that run 24/7, the power difference adds up to real money on a Canadian electricity bill over a year. Our Pi 5 vs mini PC for always-on home services post is the most honest direct comparison we have done on this question.
