Raise Bikes To The Heavens With Humble Garage Door Opener

November 30, 2025 by 10 Comments

Biking can be an incredibly rewarding hobby, but what do you do with all of your expensive pieces of metal and composite when you aren’t hitting the trails? They take up space that you could use for more bikes! [Chaz] figured there had to be a better way and discovered the unlikely solution of the humble garage opener.

Garage doors are made to lift high with moderate weight, exactly what one would expect from a bike lift. If you have high ceilings in your garage or wherever else you store your bikes there can’t be much easier than pushing a button to get your bike out of the way.

To assemble the unusual bike rack, [Chaz] mounted the motor to the wall with a few scraps of wood, and built a wooden platform that rides along the rail. This additional board allows you to use a traditional bike wheel rack to gently raise the bike. While initially [Chaz] had some questionable results, this was quickly resolved with removing the rotational elements of the mount and allowing a slight slant in the bike.

While not everyone may need to raise their bikes to the heavens, this type of simple hacking is always rewarding to see come together. If you want to see how some more bike specific tech works, check out the insides of this expensive bike seat!

How To Make Big Cabinets On A Small CNC Router

November 30, 2025 by 17 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.

DIY Light Panels Work With Home Assistant

November 29, 2025 by 2 Comments

There are a few major companies out there building colorful LED panels you can stick on your wall for aesthetic purposes. Most commercial options are pretty expensive, and come with certain limitations in how they can be controlled. [Smart Solutions For Home] has whipped up a flexible DIY design for decorating your walls with light that is altogether more customizable.

In this case, the DIY light panels ape the hexagonal design made popular by brands like Nanoleaf. In this case, each hexagon panel runs an ESP32 microcontroller, which controls a series of WS2812 addressable LEDs. This allows each panel to glow whatever color you like, and they’re arranged in an XY grid to enable you to light individual panels with a range of different geometric effects. The benefit of having a full microcontroller on each panel is that they can act quite independently—each one able to be used as a smart light, an notification display, or even as a physical button, all integrated with Home Assistant.

If you’re a fan of DIY smart home products, these might be right up your alley. They’re supremely flexible and customizable, and can do a lot of things that commercial versions can’t easily replicate. Just don’t ignore the fact that they require a considerable amount of assembly, what with the custom PCBs, 3D printed enclosures, and front diffusers to deal with. That’s just the way the LED wall crumbles.

We’ve seen other similar builds before, too. Why? The simple fact is that a lot of people want cool glowy panels on their wall without having to pay through the nose for them.

Phone-grabbing robot

This Bedtime Bot Enforces Better Sleep Hygiene

November 27, 2025 by 6 Comments

[Will Dana] is engineering his way to better sleep hygiene. Not satisfied with a simple bedtime reminder notification — such things are easily dismissed, after all — [Will] is offloading self-control onto a robot which will take his phone away at bedtime.

Scrolling in bed is allowed up to a prescribed time. At that time, a rack and pinion-mounted arm rises up from behind his mattress, presenting an open hand, ready to accept the object of his addiction. At this point, a countdown begins. If he does not hand over the device in a matter of seconds, the robot escalates by flashing obnoxiously bright lights in his face.

The nocturnal technology detox is not absolute, however. A button allows [Will] to temporarily retrieve his phone after it has been confiscated. This safety override accounts for the Inevitable situation where he will need to send a last-minute text before nodding off. The flashing light disincentive countdown is restarted upon retrieval, ensuring that [Will] does not cheat his own system for additional scroll time.

As a brief sidebar, [Will] does a nice job explaining how pulse-width modulation works for the purpose of controlling the speed of the rack and pinion mechanism.

For more of [Will’s] projects see this iPad suspension system a Lamp that tracks the location of the ISS and a drum that uses the piezoelectric effect to charge mobile devices.

Remember XBMC? It’s Back!

November 21, 2025 by 31 Comments

The original Xbox was different from the consoles that had gone before, in that its hardware shared much with a PC of the day. It was found to be hackable, and one of the most successful projects to take advantage of it was a media centre. You know it as Kodi, but its previous name was XBMC, for Xbox Media Centre. The last version that still ran on an original Xbox saw the light of day in 2016, so it’s definitely a surprise that a new version has appeared.

XBMC version 4.0 brings a host of new features to the venerable platform, including the Estuary user interface that will be familiar to users of more recent Kodi versions, a better games library, and more. The plugin system has been revamped too, and while it retains the Python 2 version from back in the day it’s promised that a Python 3 update is in the works. That’s right, it sounds as though there will be more releases. Get them from the GitHub repository.

We’re not sure how many of you have early Xbox hardware along with the inclination to use it as a media centre, after all Kodi runs so well on a lot of very accessible hardware. But we’re impressed that the developers of this release have managed so much within the confines of a machine with a 2000s-era spec, and have released it at all.

If you’re curious about Xbox hacking, take a look at some of its early history.

Damn Fine (Solar Powered) Coffee

November 19, 2025 by 30 Comments

The folks at Low Tech Magazine are here again, this time with a solar powered coffee maker. Lest you think of a large parabolic mirror with a pot at its focus, in this case the device is much more friendly. It’s a table-top appliance that relies upon a 100 W, 12 V panel for its operation.

They make the point that an electric coffee pot requires at least 300 W to work, so what’s the secret? In this case, insulation, as a standard moka pot is placed within a nichrome heating element set in mortar and surrounded by cork. On the outside are tiles, though they appear largely ornamental and the write-up suggests you could experiment with other materials to serve as an enclosure.

It appears to be an effective coffee maker, with the significant caveat that it’s hardly fast. In full sunlight the first pot takes over an hour to brew, with subsequent ones once it’s up to temperature being somewhat faster. But you can’t argue with the idea of free power, even if your favourite caffeinated beverage may now take a while to appear.

We like this idea, despite its slow brewing. We’ve featured Low Tech Magazine before, not least in their solar powered oven.

Humane Mousetrap Lets You Know It’s Caught Something

November 18, 2025 by 45 Comments

“Build a better mousetrap and the world will beat a path to your door,” so goes the saying, but VHS beat Betamax and the world hasn’t been the same since. In any case, you might not get rich building a better mousetrap, but you can certainly create something more humane than the ol’ spring’n’snap, as [nightcustard] demonstrates.

The concept is the same as many humane mousetraps on the market. The mouse is lured into a confined cavity with the use of bait, and once inside, a door closes to keep the mouse inside without injuring it. [nightcustard] achieved this by building a plastic enclosure with plenty of air holes, which is fitted with a spring-loaded door. When a mouse walks through an infra-red break beam sensor, a Raspberry Pi Pico W triggers a solenoid which releases the door, trapping the mouse inside. This design was chosen over a passive mechanical solution, because [nightcustard] noted that mice in the attic were avoiding other humane traps with obvious mechanical trigger mechanisms.

As a bonus, the wireless connectivity of the Pi Pico W allows the trap to send a notification via email when it has fired. Thus, you can wake up in the morning and check your emails to see if you need to go and release a poor beleaguered mouse back into the wild. This is critical, as otherwise, if you forget to check your humane trap… it stops being humane pretty quickly.

If you’re looking for more inspiration to tackle your mouse problems, we can help. We’ve featured other traps of this type before, too. Meanwhile, if you’ve got your own friendly homebrew solutions to pesky pest problems, don’t hesitate to hit up the tipsline.
