Smart Plugs Don’t Save You Energy, But Don’t Consume Much Either

Amazon Alexa, Google Home, and just about every electronic device manufacturer are jumping on the bandwagon of connected devices. They promise us the ability to turn on our toaster from another room, unlock our doors just by shouting at them from outside, and change the channel on our TV through perfectly enunciating a sentence instead of mashing the buttons on our remotes like chumps. And yet, despite all this new-fangled finger-less control, there is an unanswered question: does this technology save us energy in the long run?

For years we’ve been hearing about vampire power and all the devices in …read more

Their Battery is Full of Air

Storing electrical energy is a huge problem. A lot of gear we use every day use some form of battery and despite a few false starts at fuel cells, that isn’t likely to change any time soon. However, batteries or other forms of storage are important in many alternate energy schemes. Solar cells don’t produce when it is dark. Windmills only produce when the wind blows. So you need a way to store excess energy to use for the periods when you aren’t creating electricity. [Kris De Decker] has an interesting proposal: store energy using compressed air.

Compressed air storage …read more

MoAgriS: A Modular Agriculture System

Hackaday.io user [Prof. Fartsparkle] aims to impress us again with MoAgriS, a stripped-down rig for bringing crops indoors and providing them with all they need.

This project is an evolution of their submission to last year’s Hackaday Prize, MoRaLiS — a modular lighting system on rails — integrating modules for light, water, airflow, fertilizer and their appropriate sensors. With an emphasis on low-cost, a trio of metal bars serve as the structure, power and data transmission medium with SAM D11 chips shepherding each plant.

Reinforced, angled PCBs extend rails horizontally allowing the modules to be mounted at separate heights. Light …read more

Battery-Powered Watering Timer Converted to Solar on the Cheap

Watering the garden or the lawn is one of those springtime chores that is way more appealing early in the season than later. As the growing season grinds along, a chore that seemed life-giving and satisfying becomes, well, just another chore, and plants often suffer for it.

Automating the watering task can be as simple as buying a little electronic timer valve that turns on the flow at the appointed times. [A1ronzo] converted his water hose timer to solar power. Most such timers are very similar, with a solenoid-operated pilot valve in line with the water supply and an electronic …read more

A Home Network, Security System, And A Hidden Room Behind A Bookcase

Ok, now this is something special. This is a home network and security system that would make just about anyone stop, and with jaw hanging agape, stare, impressed at the “several months of effort” it took [timekillerjay] to install their dream setup. Just. Wow.

Want a brief rundown of the diverse skill set needed to pull this off? Networking, home security, home automation, woodworking, running two thousand feet(!) of cat 6a cable, a fair hand at drywall work for the dozens upon dozens of patches, painting, staining, and — while not a skill, but is definitely necessary — an amazingly …read more

Bargain Bin Barcode Scanner Keeps Track Of Shopping Needs

For most people, a Post-It note or dry-erase board suffices to ensure that household consumables are replenished when they’re used up. But hackers aren’t like most people, so this surplus barcode scanner turned kitchen inventory manager comes as little surprise. After all, if something is worth doing, it’s worth overdoing.

[Brian Carrigan]’s project began with a chance discovery of an old barcode scanner in his local scrap store. Questions as to why we can never find bargains like a $500 scanner for six bucks aside, [Brian] took the scanner home for a bit of reverse engineering. He knew it used …read more

Dumb Down Your Xiaomi Smart Lamp With A Custom Firmware

Undoubtedly, the ESP8266’s biggest selling point is its WiFi capability for a ridiculously low price. Paranoid folks probably await the day its closed-source firmware bits will turn against humanity in a giant botnet, but until then, hobbyists and commercial vendors alike will proceed putting them in their IoT projects and devices. One of those devices is the Yeelight desk lamp that lets you set its color temperature and brightness via mobile app.

[fvollmer] acquired such a lamp, and while he appreciated its design and general concept, he wasn’t happy that it communicates with external servers. So he did the only …read more

Ground-Effect Lighting For Your Bed.

If you’ve ever disturbed your partner by getting up during the night and flicking on the bathroom light — or tripping over something and startling them awake completely in the ensuing catastrophe — [Kristjan Berce]’s idea to install motion-activated ground-effect lighting on his girlfriend’s bed might hold your attention.

[Berce] is using an Arduino Nano for the project’s brain, a PIR sensor from Adafruit, and an L7805 voltage regulator to handle load spikes.  He doesn’t specify the type of LED strip he’s using, but Neopixels might be a safe bet here. Soldering issues over with, he …read more

IoT Chore Reminder for the Serially Forgetful

The secret to domestic bliss often lies in attention to detail, an area in which we can all do a little better. But if paper notes and smartphone reminders are not enough to help you remember to knock jobs off your list, perhaps this IoT task reminder will give you the edge you need to keep the peace at home.

As [Andreas Spiess] points out, his best intentions of scheduling recurring tasks in Google Calendar were not enough to keep him on on top of his share of chores around the house. He found that the notifications popping up on …read more

Secret Book Light Switch

You enter a study and see a lightbulb hanging on the bookshelf. You try all the switches in the room — nothing is turning it on. Remembering you’re in [lonesoulsurfer]’s home, you realize that you’re going to have to start yanking on every book in sight.

While often associated with the likes of Bat-caves and other complicated hidden passageways, turning a shelved book into a secret switch isn’t complex in its own right. [lonesoulsurfer] is basing their build on one by B.Light Design revolving around a fan switch, some aluminium strips, a block terminal, fishing line, a hinge, and — …read more
