Landscape to Portrait at the Click of a Mouse

Posted on by

Modern 16:9 aspect ratio monitors may be great for watching a widescreen movie on Netflix, but for most PDFs, Word documents, and certain web pages, landscape just won’t do. But if you’re not writing the next great American novel and aren’t willing to commit to portrait mode, don’t — build an auto-rotating monitor to switch your aspect ratio on the fly.

Like many of us, [Bob] finds certain content less than suitable for the cinematic format that’s become the standard for monitors. His fix is simple in concept, but a little challenging to engineer. Using a lazy susan as a …read more

Monitor All the Laundry Things with this Sleek IoT System

Posted on by

If like us you live in mortal fear of someone breaking into your house when you’re on vacation and starting a dryer fire while doing laundry, this full-featured IoT laundry room monitor is for you. And there’s a school bus. But don’t ask about the school bus.

In what [seasider1960] describes as “a classic case of scope creep,” there’s very little about laundry room goings on that escapes the notice of this nicely executed project. It started as a water sensor to prevent a repeat of a leak that resulted in some downstairs damage. But once you get going, why …read more

Send a Raspberry Pi Back in Time to 1980

Posted on by

One of our favorite hacker-scavengers on YouTube, [The Post-Apocalyptic Inventor], has been connecting his Raspberry Pi up to nearly every display that he’s got in his well-stocked junk pile. (Video embedded below.)

Modern monitors with an HDMI input connect right up to the Pi. Before HDMI came VGA, but the Pi doesn’t do that natively. One solution is to use a composite-to-VGA converter and pull the composite signal out of the audio jack. Lacking the right 4-pole audio cable, [TPAI] soldered some RCA plugs directly onto the Pi, and plugged that into the converter. On a yet-older monitor, he faced …read more

Mobile Menace Monday: Beware of monitoring apps

Posted on by

We mobile researchers sometimes classify apps in order to warn users of its presence because of its potential harm, but leave it up to the users’ discretion to remove. This is the case when it comes to a subcategory of PUPs called monitors. Monitoring … Continue reading Mobile Menace Monday: Beware of monitoring apps→

Colorful Display Keeps Track of Your Network

Posted on by

So you’ve built out your complete home automation setup, with little network-connected “things” scattered all around your home. You’ve got net-connected TVs, weather stations, security cameras, and whatever else. More devices means more chances for failure. How do you know that they’re all online and doing what they should?

[WTH]’s solution is pretty simple: take a Raspberry Pi Zero, ping all the things, log, and display the status on an RGB LED strip. (And if that one-sentence summary was too many words for you, there’s a video embedded below the break.)

Before you go screaming “NOTAHACK!”, we should let you …read more

FPGA Drives Old Laptop Screen

Posted on by

Every year, new models of laptops arrive on the shelves. This means that old laptops usually end up in landfills, which isn’t exactly ideal. If you don’t want to waste an old or obsolete laptop, though, there’s a way to reuse at least the screen out of one. Simply grab an FPGA off the shelf and get to work.

[Martin] shows us all how to perform this feat on our own, and goes into great detail about how all of the electronics involved work. Once everything was disassembled and the FPGA was wired up, it took him a substantial amount …read more
