This Quick Hack Will Keep You Online During Your Next Power Outage

Posted on by

The modern human’s worst nightmare: a power outage. Left without cat memes, Netflix, and — of course — Hackaday, there’s little to do except participate in the temporary anarchy that occurs when left without internet access. Lamenting over expensive and bulky uninterruptible power supplies, Youtube user [Gadget Addict] hacked together a UPS power bank that might just stave off the collapse of order in your household.

This simple and functional hack really amounts to snipping the end off of a USB  power cable. The cable is then attached to a screw terminal to barrel connector adapter and plugged it into …read more

Sandwich Robot Keeps You Fed So You Can Keep Hacking

Posted on by

Food. A necessary — often delicious — interruption of whatever project you’re currently hacking away at. Ordering takeout gets expensive and it’s generally unhealthy to subsist solely on pizza. With the Sandwich-O-Matic, a simple voice command fulfills this biological need with minimal disturbance of your build time.

Built for a thirty-six hour hackathon, the Sandwich-O-Matic is controlled by a Photon and an Arduino. The backend is running node, hosted on AWS, and Google Cloud was used for voice to text recognition. This thing is a fully automated and voice controlled sandwich building station. A DC motor services the toaster, while …read more

Faulty Parking Meter Tracking System? RFID To The Rescue!

Posted on by

How often do you see problems that need fixing? How often do you design your own solutions to them — even if they won’t be implemented at scale? Seeing that many of the municipal parking lots in his native Sri Lanka use a paper ticketing system which is prone to failure, [Shazin Sadakath] whipped up his own solution: an efficient RFID tag logging system.

Digging out an HZ-1050 RFID reader — as well an RFID card and two tags — [Sadakath] set to work connecting it to his Raspberry Pi and cooking up a batch of code and a dashboard …read more

Barely-There GSM GPS Tracker

Posted on by

What’s the most un-intrusive GPS you’ve ever seen? How about for a bike? Redditor [Fyodel] has built a Teensy-based GPS/GSM tracker that slides into your bike’s handlebars and really is out of sight.

The tracker operates on T-Mobile’s 2G service band — which will enable the device to work until about 2020 — since AT/T is phasing out their service come January. Since each positioning message averages 60 bytes, an IoT data plan is sufficient for moderate usage, with plans to switch over to a narrow-band LTE service when it becomes more affordable. [Fyodel] admits that battery life isn’t ideal …read more

Star Trek Phone Dock Might as Well Be From Picard’s Night Stand

Posted on by

Star Trek is often credited with helping spur the development of technologies we have today — the go-to example being cell phones. When a Star Trek April Fool’s product inspires a maker to build the real thing? Well, that seems par for the course. [MS3FGX] decided to make it so. The 3D printed Star Trek-themed phone dock acts as a Bluetooth speaker and white noise generator. The result is shown off in the video below and equals the special effects you expect to find on the silver screen.

Taking a few liberties from the product it’s based on — which …read more

Waiting For A Letter? This IoT Mailbox Will Tell You Exactly When It Arrives.

Posted on by

If you’re waiting for a much sought-after letter, checking your mailbox every five minutes can be a roller-coaster of emotion — not to mention time-consuming. If you fall into this trap, Hackaday.io user [CuriosityGym] as whipped up a mailbox that will send off an email once the snail-mail arrives.

The project uses an Arduino Uno, an ESP 8266 wifi module, and an idIoTware shield board — making specific use of its RGB LED and light dependent resistor(LDR). Configuring the RGB LED on the idIoTware board to a steady white light sets the baseline for the LDR, and when …read more

Ikea Desk Lamp That Will Defend Your Lungs

Posted on by

While some people may enjoy the occasional whiff of noxious smells — gasoline, axe body spray, etc — prolonged exposure to fumes is not good for your health. This goes for soldering too, isn’t it about time you added some abatement to your bench tools?

Inspired by some of the fume hoods we’ve featured before — take note, ye who art lacking projects — [Georg Sluyterman] put together his own Ikea lamp fume extractor.

The most striking feature is that it’s mounted on an Ikea desk lamp making for convenient positioning and minimal clutter. A NeoPixels strip lights …read more

Archaeology, Virtually.

Posted on by

Drone technology is seeing useful application in a new field seemingly every day — so it was only a matter of time before it saw use in archaeology. And so, a team of researches in Australia are combining drone and VR modeling technology to help investigate the Plain of Jars, in Laos.

After the drone images the site, those photos are patched together by object recognition software and are reviewed in the immersive CAVE2 3D facility at Melbourne, Australia’s Monash University. Multiple surveys catalog and archive the dig at various stages and enable the archaeologists to continue investigating the site …read more
