An Overly Complicated Method Of Tracking Your Favorite Sports Team

December 4, 2021 by 3 Comments

Much of the world appears to revolve around sports, and sports tracking is a pretty big business. So how do people keep up with their favorite team? Well, [Jackson] and [Mourad] decided to devise a custom IoT solution.

Their system is a bit convoluted, so bear with us. First, they tell Alexa whether or not the team won or lost that week. Alexa then sends that information to IFTTT where two different Particle Argon boards are constantly polling the results to decide how to respond next. One Particle responds by lighting up an LED, green for a win and red for a loss. Another Particle board displays the results on an LCD screen. But this is where things get tricky. One of the more confusing aspects of their design is one of the Particle boards then signals back to IFTTT, telling it to tally the number of wins and losses. This seems a bit roundabout since the system started with IFTTT in the first place. Regardless, they seemed to be happy with the result and I’m sure they learned something in the process.

This project might not fulfill any functional need given that Alexa knows everything about all our lives already and you could just ask her how your favorite team is doing whenever you want to. But hey, we’re all about learning by doing here at Hackaday and we’re all guilty of building useless projects here and there just because we can. In any case, their project could serve as a good intro to integrating your Particle with IFTTT or Alexa since there appears to be quite a bit of probably unnecessary handshaking going on here.

PIR Sensor In A Jar Helps You Keep Your Concentration

December 24, 2020 by 16 Comments

While there are loads of impressive and complex projects here on Hackaday, sometimes it’s the simple ones that really speak to us. In this case we were presented with [Isabell Park]’s easy-to-follow instructable on how to build an anti-procrastination device.

On the hardware side there are no surprises, it consists of a PIR sensor connected to a NodeMCU microcontroller. It checks for a signal from the sensor, and if it’s triggered, it sends a command through the Adafruit IO libraries to IFTTT. On its own it could make for a decent movement alarm, but the part that makes the project interesting is how it’s applied to become a device to help with procrastination instead.

First, you put your phone in a jar along with the electronics and close it. Then, with everything configured, the circuit is powered on and stays vigilant for any movement inside the jar. Should you try to take your phone out of it for a quick social media break (which, if you’re like us, can turn into a few hours), IFTTT will be alerted and run through whatever script you have in place. In [Isabell]’s case, she suggests sending an SMS to a trusted contact to keep you in check.

If you’re looking to keep track of how much time you’ve spent procrastinating, have we got a clock for you. But if you’re looking for more projects involving PIR sensors, we have one that alerts you when your cat is back home. Meanwhile, check out this one in action after the break.

You’ve Got Rat!

August 1, 2020 by 34 Comments

If you home has never been subject to a rodent invasion then you are fortunate. Our world is full of rats and mice, and despite the best efforts of humanity to keep them at bay it is inevitable that a few will find their way through. For [Marius Taciuc] this became a problem, as his traps needed constant checking to avoid the prospect of a festering rat carcass. His solution? A humane trap equipped with an ESP8266, that notifies him when the rodent is incarcerated.

The tech behind it is about as simple as it’s possible to get, the trap’s door activates a switch, that powers on an ESP8266 module. The ESP’s code simply wakes it up, connects to a wireless network, and sends a query to IFTTT with a call to a service that sends him an email alert. There’s no need to monitor any GPIO lines or have any code running to keep an eye on the trap, it’s all purely a function of the power switch.

The trap itself is interesting, in that it’s a home-made one constructed from soldered copper wire. Sadly there are few details of its construction, but you can see more of it including a live rat inside it, in the video below the break. And if making a trap catches your interest, we can help you there.

Clear Some Space And Build A Cosmo Clock

May 10, 2020 by 4 Comments

Like many of us, [Artistikk] is inspired by astronauts and space travel in general. To keep the inspiration coming, he made the Cosmo Clock — a sleek little clock that changes color whenever an astronaut is launched into space.

As awesome as space is, we’re inspired by the amount of Earth-saving reuse going on in this project. The actual time-telling is coming from a recycled wristwatch movement. [Artistikk] cut a bigger set of hands for it out of a plastic container, and used the lid from another container for the clock’s body.

The launch inquiries are handled by an ESP8266, which uses a Blynk app and some IFTTT magic to get notified whenever NASA yeets an astronaut into space. Then the ESP generates random RGB values and sends them to a single RGB LED. The clock body is small enough that a single LED is bright enough to light up all the parts that aren’t blacked out with thick paper. In case you’re wondering, the pattern around the edge isn’t random, it’s Morse code for ‘sky’, but you probably already knew that, right? Make a dash past the break to take the tour.

Clocks that wind up in space are much more complicated. Check out this tear-down of the clock from a late-90s Soyuz spacecraft.

IoT Cassette Scroller Never Needs A Pencil

March 10, 2020 by 33 Comments

The see-through electronics craze of the ’80s and ’90s clearly had an effect on [MisterM], and we can totally relate. Those candy-colored components inside undoubtedly launched a few thousand kids in the direction of electronics, as we can attest.

Though the odds seemed very much against him, [MisterM] was able to fit all the necessary components for a scrolling IoT notifier inside a standard cassette tape. It took a bit of surgery on both the Raspberry Pi Zero W and the donor cassette in the name of getting all the components to fit in such a tight space. We’re glad he kept at it, because it looks amazing.

The Raspi uses Adafruit.IO and IFTTT to get all kinds of notifications — tweets, weather, soil moisture, you name it — and scrolls them across an 11×7 LED matrix. A vibrating disc motor gives a buzzing heads up first, so [MisterM] doesn’t miss anything. Hit the break button and flip this thing over, because the build video is all queued up on the B-side.

If you’d rather play around with cassette decks, add in some playback speed potentiometers to mess with the sound, or go all out and make a Mellotron.

NFC For Your Home Automation

January 30, 2020 by 26 Comments

If home automation in the IoT era has taught us anything, it is that no one wants to run wires. Many of us rent, so new cabling is not even an option, even if we wanted to go that route. If you want a unique sensor, you have to build your own, and [tmkThings] wanted an NFC scanner at his front door. Just like arriving at work, he scans his credentials, and the door unlocks automagically.

Inside a little white box, we find an ESP8266 speaking Wifi attached to a PN532 talking NFC, and both are familiar names on these pages. The code, which is available on GitHub, links up with IFTTT and MQTT. For the security-minded, we won’t see this on your front door, but you can trigger your imagination’s limit of events from playing your favorite jams at the end of the day to powering down all the televisions at bedtime.

NFC hacks are great because they are instantly recognizable and readers are inexpensive, but deadbolt hacking is delightful in our books.

Hardware Notifications For ISS Flybys

July 16, 2019 by 3 Comments

Since Sputnik launched in the 1950s, its been possible to look outside at night and spot artificial satellites orbiting with the naked eye. While Sputnik isn’t up there anymore, a larger, more modern satellite is readily located: the International Space Station. In fact, NASA has a program which will alert anyone who signs up when the ISS is about to fly overhead. A better alert, though, is this ISS notifier which is a dedicated piece of hardware that guarantees you won’t miss the next flyby.

This notifier is built around the Tokymaker, a platform aimed at making electronics projects almost painfully easy to learn. Connections to various modules can be made without soldering, and programming is done via a graphical interface reminiscent of Scratch. Using these tools, [jaime_lc98] designed a tool which flips up a tiny paper astronaut whenever the ISS is nearby. The software side takes advantage of IFTTT to easily and reliably control the servo on the Tokymaker.

The project pages goes into detail about how to set up IFTTT and also how to use the block-style language to program the Tokymaker. It’s pretty straightforward to get it up and running, relatively inexpensive, and looks like a great way to get the miniature hackers in your life excited about space. If they happen to learn a little something in the proces, well, we won’t tell them if you won’t. It might also be a good stepping stone on the way to other ISS-related hacks.
