Our Home Automation Contest Starts Now!

February 20, 2024 by Elliot Williams 32 Comments

Your home is your castle, and what’s better than a fully automatic castle? Nothing! That’s why we’re inviting you to submit your sweetest home automation hacks for a chance to win one of three $150 DigiKey gift certificates. The contest starts now and runs until April 16th.

Home buttons project, simple home automation display — [Matej]’s Home Buttons gets the job done in open-source style.

We love to play around with home automation setups and have seen our fair share, ranging from the simple “turn some lights on” to full-blown cyber-brains that learn your habits and adapt to them. Where is your project on this continuum?

Whether you’re focused on making your life easier, saving energy, gathering up all the data about your usage patterns, or simply stringing some random functions together and calling it a “system,” we’d like to see it. Nothing is too big or too small if it makes your home life easier.

Home is where the home automation is!

To enter, head over to Hackaday IO and start documenting your project there. We are, of course, interested in learning from what you’ve done, so the better the docs, the better your chances of winning. And if you need some inspiration, check out these honorable mention categories.

Honorable Mention Categories

Creature Comforts: Does your system make your house a home? Maybe it turns on and off the heaters to keep rooms just right, opens and closes the blinds for you, or maybe it turns on the nightlights when you’re heading downstairs for a midnight snack. The Creature Comforts category is for you.
Efficiency: Automation isn’t just about convenience, but can help us save energy too. If your machines help you save money on your power and heating bills, show us!
Rube Goldberg: A “system” sounds so formal, but a lot of ad hoc home automation projects are nonetheless super effective. If your home system grew organically and maybe resembles a collection of hacks more than a carefully orchestrated plan, it could be a Rube Goldberg setup.
All the Data: An automatic home makes a lot of data along the way. If you have a slick system for displaying it, or even just collecting it all, we’d love to see it.
Retrofit: Not everything works like you’d want it to out of the box. Maybe you’ve hacked into an air purification system or your washing machine to get it to play along? That’s a home automation retrofit.

Thanks again to DigiKey for sponsoring this with three gift certificates!

2023 Halloween Hackfest: This Year’s Spooky Winners

November 20, 2023 by Tom Nardi 1 Comment

With the zombies, ghouls, and ghosts now safely returned to their crypts until next October, it’s time to unveil this year’s winners for the 2023 Halloween Hackfest.

For this contest, sponsors DigiKey and Arduino challenged the community to come up with their best creations for what’s arguably the most hacker-friendly of holidays. Pretty much everything was fair game, from costumes to decorations. The top three winners will get $150 credit from DigiKey and some treats from Arduino — just don’t try to eat them.

2023 Halloween Hackfest: A Spooky “Severance” Speaker

October 18, 2023 by Kristina Panos 2 Comments

If you know, you know. After becoming fully engrossed in the sci-fi psycho-thriller “Severance“, [Ben Brooks] absolutely needed to have a version of the ominous speaker known as the Board.

This speaker represents the Board, who is the enigmatic governing body of Lumon Industries, the fictional and gigantic biotechnology company featured in the show.

The Board cultivates an air of mystery by rarely speaking, and when it does, it speaks through a single person who paraphrases the Board’s responses. The audio that comes out is a mix of the show’s theme song, pertinent show quotes, and static.

The guts of this freaky little thing are pretty simple — an ESP8266, a DF Player Mini, and a couple of small speakers. In fact, [Ben] had all the parts leftover from a previous home automation project, including the PCB.

Although the original plan was to program it in Arduino, [Ben] ended up using ESPHome to make it easier to integrate with sensors for the big night. Be sure to check out the demo video after the break.

We’ve seen a few fun hacks for the porch this year, including the treat trough of terror and this Ouija robot that out-creeps the real thing.

2023 Halloween Hackfest: Candy Basket Sees You Coming

October 14, 2023 by Kristina Panos 5 Comments

On Halloween, some people can’t or don’t want to open the door for various reasons. Maybe they have a cat that likes to escape every chance it gets, or maybe their favorite TV show is on during prime trick-or-treating time. Whatever the case, we think it’s perfectly acceptable to leave a bowl of candy outside the door, especially if there are electronics involved.

In this case, the bowl detects trick-or-treaters and candy eaters using an LD2410 60 GHz radar sensor and an RP2040. A light pipe shows orange when a person is detected, and switches over to green as they come closer, as if to say you may have candy now.

Nothing happens after that, but now that we think about it, it would be cool to add an MP3 decoder and a speaker to play a little witch cackle or something once they’ve had a chance to stick their hand in the bucket.

[Mike Kushnerik] actually designed the PCB a few months ago for non-Halloween purposes: some home automation projects. But then they were trying to think of something for Halloween, and this delightful light-up bucket came to mind. In addition to the RP2040 chip, there’s a 128 MB flash chip, a WS2812 LED, and a header for communicating with the radar sensor over UART. Be sure to check out the brief demo video after the break.

If you’d like to stand outside and give out candy, at least send it down a light-up slide or something.

2023 Halloween Hackfest: Flickering Pumpkin Pin Is Solidly Built

October 4, 2023 by Kristina Panos 9 Comments

Now first of all, [Steph] grants that you can already take your pick of several LED pumpkin badges out there on IO. That’s not the point. The point is that this flickering pumpkin pin is nicely-built as well as being open source.

Even though it’s fully featured — it flickers, it’s wearable, and it’s lightweight — the build couldn’t be more simple. It’s fancy through-hole LEDs and a coin cell holder, plus a tack pin to stick it through your shirt. But the final result is quite elegant thanks to clever use of PCB layering.

The first version was to get all the layers right to let the light through and embellish the jack-o-lantern’s lines with manufacturer-applied silver solder, but as [Steph] points out, it looked ‘like something a disturbed child might carve into their desk in detention’. So [Steph] enlisted [Mx. Jack Nelson], who improved the artwork.

Pretty much every component does double duty here, including the tack pin — it serves as a switch because it can hold the battery in place. The battery’s edges reflect the glowing light quite nicely around the edge of the pin. And the LEDs beneath the battery prevent it from slipping out. You can see how it goes together in the video after the break.

Hackaday Prize 2023: The Wildcard Finalists Are Here

October 4, 2023 by Tom Nardi 5 Comments

We’re in the endgame now — there’s just about a month to go before the final results are announced for the 2023 Hackaday Prize, which means all of our finalists are in a mad rush to put the finishing touches on their respective projects. Today, ten more hackers are about to feel the heat as we announce our final group of finalists from the Save the World Wildcard round.

As finalists, each of these projects has been awarded $500 to help further their development. But perhaps more importantly, they are now officially in the running for one of the final six awards, which includes the Grand Prize of $50,000 and a residency at the Supplyframe DesignLab.

Hello, Halloween Hackfest!

September 19, 2023 by Elliot Williams 1 Comment

Halloween is possibly the hackiest of holidays. Think about it: when else do you get to add animatronic eyes to everyday objects, or break out the CNC machine to cut into squashes? Labor day? Nope. Proximity-sensing jump-scare devices for Christmas? We think not. But for Halloween, you can let your imagination run wild!

We’re happy to announce that DigiKey and Arduino have teamed up for this year’s Hackaday Halloween Contest. Bring us your best costume, your scariest spook, your insane home decorations, your wildest pumpkin, or your most kid-pleasing feat!

We’ll be rewarding the top three with a $150 gift certificate courtesy of DigiKey, plus some Arduino Halloween treats if you use a product from the Arduino Pro line to make your hair-raising fantasy happen.

We’ve also got five honorable mention categories to inspire you to further feats of fancy.

Costume: Halloween is primarily about getting into outrageous costumes and scoring candy. We don’t want to see the candy.
Pumpkin: Pumpkin carving could be as simple as taking a knife to a gourd, but that’s not what we’re after. Show us the most insane carving method, or the pumpkin so loaded with electronics that it makes Akihabara look empty in comparison.
Kid-Pleaser: Because a costume that makes a kid smile is what Halloween is really all about. But games or elaborate candy dispensers, or anything else that helps the little ones have a good time is fair game here.
Hallowed Home: Do people come to your neighborhood just to see your haunted house? Do you spend more on light effects than on licorice? Then show us your masterpiece!
Spooky: If your halloween build is simply scary, it belongs here.

Head on over to Hackaday.io for the full details. And get working on your haunts, costumes, and Rube Goldberg treat dispensers today.
