[Emily Velasco] has an internet provider that provides sub-par connectivity. Instead of repeatedly refreshing a browser tab to test if the network is up, [Emily] decided to create an internet status monitor by embedding indicator lights in a cat skull…for some reason.

The electronics are straightforward, with the complete parts list consisting of an Arduino Nano 33 IoT device connected to a pair of RGB LEDs and 50 Ohm resistors. The Nano attempts to connect to a known site (in this case, the Google landing page) every two seconds and sets the LEDs to green if it succeeds or red if it fails.

The cat skull is thankfully a replica, 3D printed by one of [Emily]’s Twitter acquaintances, and the whole project was housed in a domed security camera enclosure. [Emily] mounts the LEDs into the skull to create a “brain in a jar” effect.

The source is available on GitHub for those wanting to take a look. We’ve featured internet connectivity status indicators in the form of traffic lights here before, as well as various network status monitors and videoconferencing indicator lights.

If you’re like us, you probably spend more time browsing Reddit than you’d like to admit to your friends/family/boss/therapist. A seemingly endless supply of knowledge, wisdom, and memes; getting stuck on Reddit is not unlike looking something up on Wikipedia and somehow managing to spend the next couple hours just clicking through to new pages. But we’re willing to bet that none of us love browsing Reddit quite as much as [Saad] does.

He writes in to tell us about the handheld device he constructed which lets him view random posts from the popular /r/showerthoughts sub. Each press of the big red button delivers another slice of indispensable Internet wisdom, making it a perfect desk toy to fiddle with when you need a little extra push to get you through the day. Like one of those “Word a Day” calendars, but one that you’ll actually read.

For those curious as to how [Saad] is scraping Reddit with an Arduino, the short answer is that he isn’t. Posts are pulled from Reddit using an online tool created for the project by his wife (/r/relationshipgoals/), and dumped into a text file that can be placed on the device’s SD card. With 1500 of the all-time highest rated posts from /r/showerthoughts onboard, he should be good on content for awhile.

[Saad] has done an excellent job documenting the hardware side of this build, providing plenty of pictures as well as a list of the parts he used and a few tips to help make assembly easier. Overall it’s not that complex a project, but his documentation is a big help for those who might not live and breathe this kind of thing.

For the high-level summary: it uses an Arduino Pro Mini, a ILI9341 screen, and a 3.3 V regulator to step down 5 V USB instead of using batteries. A bit of perfboard, a 3D printed case, and a suitably irresistible big red button pulls the whole thing together.

We’ve seen a similar concept done in a picture frame a couple of years back, but if that’s not interactive enough you could always build yourself a Reddit “controller”.

There’s a lot going on our virtual spaces, and anyone with a smart phone can attest to this fact. There are pop-up notifications for everything you can imagine, and sometimes it’s possible for the one really important notification to get lost in a sea of minutiae. To really make sure you don’t miss that one important notification, you can offload that task to your own personal dinosaur.

The 3D-printed dinosaur has a rack-and-pinion gear set that allows it to extend upwards when commanded. It also has a set of LEDs for eyes that turn on when it pops up. The two servos and LEDs are controlled by a small Arduino in the base of the dinosaur. This Arduino can be programmed to activate the dinosaur whenver you like, for an email from a specific person, a reply to a comment on Reddit, or an incoming phone call to name a few examples. Be sure to check out the video below the break.

With this dinosaur on your desk, it’s not likely you’ll miss its activation. If you’d like something that has the same function but with less movement and more lights, there’s also a notification 3D cube made out of LEDs that’s sure to catch your eye as well.

This was gonna happen – sooner or later. [matthewhallberg] built a “Smart” trash can that is connected to the Internet and can be controlled by its own Android App. We’re not sure if the world needs it, but he wanted one and so built it. He started it out on a serious note, but quickly realized the fun part of this build – check out his funny Infomercial style video after the break.

The build itself is uncomplicated and can be replicated with ease. A servo motor helps flip the lid open and close. This is triggered by an ultrasonic ping sensor, which responds when someone waves a hand in front of the trash can. A second ping sensor helps inform the user when it is full and needs to be emptied. A Leonardo with the Idunio Yun shield helps connect the trash can to the internet. An mp3 shield connected to a set of powered computer speakers adds voice capability to the trash can, allowing it to play back pre-recorded sound clips. Finally, a Bluetooth module lets him connect it to an Android phone and the companion app controls the trash can remotely.

For the IoT side of things, [matthewhallberg] uses a Temboo account to send an email to the user when the trash can is full. The Arduino sketch, a header file to configure the Temboo account, and the Android application can all be downloaded from his blog. If this project inspires you, try building this awesome Robotic trash can which catches anything that you throw near it  or read the barcodes off the trash being thrown out and update the grocery list.

Using an Arduino or Raspberry Pi to perform a task in the real world is certainly a project we’ve seen here before, and certainly most of these projects help to make up the nebulous “Internet of Things” that’s all the rage these days. Once in a while though, a project comes along that really catches our eye, as is the case with [Jamie’s] meticulously documented automatic garage door opener.

This garage door opener uses an ATMega328 to connect the internet to the garage door. A reed switch is installed which lets the device sense the position of the door, which is relayed back to the internet. [Jamie] wrote an Android app that can open and close the door and give the user the information on the door’s status. One really interesting feature is the ability to “crack” the garage door. This is done by triggering the garage door opener twice with a delay in between. From the video after the break we’d say this is how [Jamie’s] cat gets in and out.

We love seeing projects that are extremely well documented so that anyone who wants to make one can easily figure out how. Internet-connected garage door openers have been featured in other unique ways before too, but we’ve also seen ways to automatically open blinds or chicken coops!

Hackaday – and the projects featured on Hackaday – get a lot of flak in the comments section simply for mentioning an Arduino. The Arduino complainers are, of course, completely wrong; everyone here is trying to make something, not make something in the most obscure possible way.

The Arduino is a legitimate tool, but still there are those among us who despise anything ending in ~duino. This browser plugin is for them. It’s a Chrome extension that selectively replaces or removes Arduino content from Hackaday depending on the user’s preference.

There are three settings to the plugin: See No Evil replaces images of Arduinos with serious business. Hear No Evil removes all occurrences of the word ‘Arduino’ and replaces them with something of your choosing. Speak No Evil removes all posts in the Arduino Hacks category.The last option also removes the ability to comment on any post in the Arduino Hacks category, so obviously the quality of the comments here will drastically increase by tomorrow.

You can grab the plugin on the gits. It’s Chrome only, but if someone wants to port it to Firefox, we’ll gladly put up another post.

There you go, Internet. You’re free now, and the biggest problem in your life has now been solved. Go give [SickSad] a virtual pat on the back, or tell him he could have done the same thing with a 555. Either of those are pretty much the same thing at this point.
