Trying To Build Your Own Consumer-Grade Router In 2026

April 16, 2026 by Maya Posch 47 Comments

Although we have many types of networking equipment with many unique names, at their core they can usually be reduced to just a computer with some specific peripherals. This is especially the case for something like a router, a device found in just about any home these days. Certain consumer-grade routers may contain something special like a VDSL modem, but most of them just have a WAN Ethernet jack on one end and one or more LAN-facing Ethernet ports.

All further functionality is implemented in software, including any firewall, routing and DHCP features. What this means is that any old PC with at least two Ethernet ports or equivalent can be a router as long as you install the appropriate software.

In this article we’ll be taking a look at what consumer-level options there exist here today, ideally something so simple that the average home user could set it up with a bit of coaching.

Anything Can Be A Router, If You Try Hard Enough

April 2, 2026 by Jenny List 17 Comments

If you’re an American and you use the Internet at home, it seems probable that routers are going to be in short supply. The US government recently mandated all such devices be home grown for security reasons, which would be fine were it not that the US has next-to-no consumer-grade router manufacturing industry.

So if you’re in the US and you need a router, what can you do? [Noah Bailey] is here from Canada to point out that almost anything (within reason) in computer terms can be made to perform as a router.

The piece is really a guide to setting up a Linux router, which he does on a small form factor PC and a hacked-together assembly of old laptop, PCI-express extender, and scrap network kit. In its most basic form a router doesn’t need the latest and greatest hardware, so there exists we’re guessing almost two decades of old PCs just waiting to be pressed into service. Perhaps it won’t help the non-technical Man In The Street much, but maybe it’ll inspire a few people to save themselves a hefty bill when they need to connect.

How To Make Big Cabinets On A Small CNC Router

November 30, 2025 by Zoe Skyforest 18 Comments

It’s easy to build big wooden furniture if you have a massive industrial CNC router, but few of us are so lucky. However, you can still build sizable stuff with a smaller router if you know what you’re doing. [Aribabox] shares some useful tricks and techniques for building large workshop cabinets on smaller machines.

The key to doing this well is modularity. [Aribabox] shows off how to build excellent workshop drawers in pieces using a stackable design. Rather than having to cut out one huge side panel to cover the whole stack of drawers, each drawer can have its own side panel that easily fits on a smaller router. They can then be stacked into a stout assembly that still does its job perfectly well. Assuming your CNC router is trued up properly, you can whip up a lot of furniture quickly, just assembling everything with screws. You’ll still be able to work faster and make bigger things easier on a big machine, but a small machine can do a lot more than you think.

[Aribabox] supplies design files for a cost if you’re eager to replicate their work. If that doesn’t suit you, you can always just use the video as inspiration to work on your own modular furniture designs instead. We’ve featured other modular furniture designs before, too, that rely on 3D printed and lasercut components.

Tiny UPS Keeps WiFi Online

October 24, 2025 by Bryan Cockfield 29 Comments

For any mission-critical computer system, it’s a good idea to think about how the system will handle power outages. At the very least it’s a good idea to give the computer enough time to gracefully shut down if the power outage will last for an indefinite time. But for extremely critical infrastructure, like our home Wi-Fi, we might consider a more long-term battery backup that can let us get through the longest of power outages.

Part of why this project from [Next Builder] works so well is that most off-the-shelf routers don’t actually use that much energy. Keeping that and a modem online when the power is out only requires a few lithium batteries. To that end, three lithium ion cells are arranged in series to provide the router with between 9 and 12 volts, complete with a battery management system (BMS) to ensure they aren’t over- or under-charged and that they are balanced. The router plugs directly into a barrel jack, eliminating any switching losses from having to use an inverter during battery operation.

While [Next Builder] is a student who lives in an area with frequent interruptions to the electricity supply, this does a good job of keeping him online. If you’re planning for worse or longer outages, a design like this is easily adapted for more batteries provided the correct BMS is used to keep the cells safely charged and regulated. You can also adapt much larger UPS systems to power more of your home’s electrical system, provided you can find enough batteries.

3D Printed Spirograph Makes Art Out Of Walnut

May 2, 2025 by Tyler August 9 Comments

Who else remembers Spirograph? When making elaborate spiral doodles, did you ever wish for a much, much bigger version? [Fortress Fine Woodworks] had that thought, and “slapped a router onto it” to create a gorgeous walnut table.

Hands holding a 3d printed sanding block, shaped to fit the grooves routed in the table which is visible in the background. — This printed sanding block was a nice touch.

The video covers not only 3D printing the giant Spirograph, which is the part most of us can easily relate to, but all the woodworking magic that goes into creating a large hardwood table. Assembling the table out of choice lumber from the “rustic” pile is an obvious money-saving move, but there were a lot of other trips and tricks in this video that we were happy to learn from a pro. The 3D printed sanding block he designed was a particularly nice detail; it’s hard to imagine getting all those grooves smoothed out without it.

Certainly this pattern could have been carved with a CNC machine, but there is a certain old school charm in seeing it done (more or less) by hand with the Spirograph jig. [Fortress Fine Woodworks] would have missed out on quite the workout if he’d been using a CNC machine, too, which may or may not be a plus to this method depending on your perspective. Regardless, the finished product is a work of art and worth checking out in the video below.

Oddly enough, this isn’t the first time we’ve seen someone use a Spirograph to mill things. It’s not the first giant-scale Spirograph we’ve highlighted, either. To our knowledge, it’s the first time someone has combined them with an artful walnut table.

Handheld Compass CNC Lets Teensy Do The Driving

February 23, 2025 by Tom Nardi 20 Comments

If somebody asked you to visualize a CNC router, you’d probably think of some type of overhead gantry that moves a cutting tool over a stationary workpiece. It’s a straightforward enough design, but it’s not without some shortcomings. For one thing, the scale of such a machine can quickly become an issue if you want to work on large pieces.

But what if you deleted the traditional motion system, and instead let the cutting tool roam freely? That’s the idea behind the open source Compass Handheld CNC. Looking a bit more like a combat robot than a traditional woodworking tool, the Compass tracks its movement over the workpiece using a Teensy 4.1 microcontroller and four PMW3360 optical flow sensors. With a pair of handles that look like a flight yoke and a display that shows the router’s current position versus where it should be, the user can “drive” the tool to cut or carve the desired design.

Admittedly, the Compass doesn’t pack quite the same punch as a more traditional setup. Rather than a beefy spindle motor or a full-sized consumer router clamped up in the gantry, the Compass uses a Dremel 3000. It’s fine for routing out an engraving and other fine work, but you wouldn’t want to use it for cutting thick stock. To help keep the work area clear and prevent dust and chips from jamming up the works, the 3D printed body for the tool includes a connection for a dust collection system.

If this all seems familiar, you may be remembering a tool we first covered nearly a decade ago — the Shaper Origin. That router, which is still on the market incidentally, utilizes optical tracking and fiducial markers to keep track of its position. We’d be interested in seeing how well the Compass compares over large distances without similar reference points.

OpenWRT, But On An Unsupported Router

December 26, 2024 by Jenny List 15 Comments

Everyone likes something cheap, and when that cheap thing is a router that’s supported by OpenWRT, it sounds like a win. [Hennung Paul] ordered a Wavlink WL-WN586X3 for the princely sum of 39 Euros, but was disappointed to find his device a rev. 2 board rather than the rev.1 board supported by the Linux distribution. Toss it on the failed projects pile and move on? Not at all, he hacked together a working OpenWRT for the device.

It’s fair to say that a majority of Hackaday readers will have familiarity with Linux, but that’s something which runs on a sliding scale from “Uses Ubuntu a bit” all the way to “Is at one with the kernel”. We’d rate ourselves somewhere around halfway along that scale in terms of having an in-depth knowledge of userland and a working knowledge of some of the internals which make the operating system tick even if we’re apprehensive about tinkering at that level. [Henning] has no such limitations, and proceeds to take the manufacturer’s distribution, itself a heavily modified OpenWRT, and make it his own. Booting over tFTP we’re used to, and we’re particularly impressed to see him using a Raspberry Pi as a surrogate host for the desoldered Flash chip over SPI.

It’s a long path he takes to get the thing working and we’re not sure we could follow it all, but we hope that the result will be a new device added to OpenWRT’s already extensive support list. It’s sometimes a shock to find this distro is now over two decades old.
