Collaborate Disseminate
It’s hard not to feel the constant pull on our limited attention from the very interesting rectangles in our pockets and packs. [Antoine Pintout] is fighting against it with three interesting pendants.
The three objects each have functions. Sablier, tells time, but rather than giving the numerals it vibrates on …read more

[André Biagioni] is developing an open hardware bicycle navigation device called Aurora that’s so gorgeous it just might be enough to get you pedaling your way to work. This slick frame-mounted device relays information to the user through a circular array of SK6812 RGB LEDs, allowing you to find out …read more
Knowing in what absolute direction your robot is pointed can be crucial, and expensive systems like those used by NASA on Mars are capable of calculating this six-dimensional heading vector to within around one degree RMS, but they are fairly expensive. If you want similar accuracy on a hacker budget, …read more
Just when you though it was safe to venture out, the National Oceanic and Atmospheric Administration released an unexpected update. Magnetic North is on the move — faster than expected. That’s right, we know magnetic north moves around, but now it’s happened at a surprising rate. Instead of waiting for …read more

Compass, the real estate tech platform that is now worth $4.4 billion, has made an acquisition to give its agents a boost when it comes to looking for good leads on properties to sell. It is acquiring Contactually, an AI-based CRM platform designed specifically for the industry, which includes features like linking up a list […] Continue reading Compass acquires Contactually, a CRM provider to the real estate industry
Virtual reality systems have been at the forefront of development for several decades. While there are commercial offerings now, it’s interesting to go back in time to when the systems were much more limited. [Colin Ord] recently completed his own VR system, modeled on available systems from 20-30 years ago, which gives us a look inside what those systems would have been like, as well as being built for a very low cost using today’s technology.
The core of this project is a head tracker, which uses two BBC Microbits as they have both the accelerometer and compass needed to …read more
If you carry a smartphone around in your pocket, you have a GPS navigation system, a compass, an altimeter, and a very powerful computer at your fingertips. It’s the greatest navigational device ever created. To use this sextant of the modern era you’ve got to look down at a screen. You need to carry a phone around with you. It’s just not natural.
For this entry into the Hackaday Prize, [Vojtech Pavlovsky] has an innovative solution to direction finding that will give you a sixth sense. It’s a headband that turns your temples into the input for a clever way …read more

Our recent “Retrotechtacular” feature on an early 1970s dead-reckoning car navigation system stirred a memory of another pre-GPS solution for the question that had vexed the motoring public on road trips into unfamiliar areas for decades: “Where the heck are we?” In an age when the tattered remains of long-outdated paper roadmaps were often the best navigational aid a driver had, the dream of an in-dash scrolling map seemed like something Q would build for James Bond to destroy.
And yet, in the mid-1980s, just such a device was designed and made available to the public. Dubbed Etak, the system …read more

When project inspiration strikes, we’d love to do some quick tests immediately to investigate feasibility. Sadly we’re usually far from our workbench and its collection of sensor modules. This is especially frustrating when the desired sensor is in the smartphone we’re holding, standing near whatever triggered the inspiration. We could download a compass app, or a bubble level app, or something similar to glimpse sensor activity. But if we’re going to download an app, consider Google’s Science Journal app.
It was designed to be an educational resource, turning a smartphone’s sensor array into a pocket laboratory instrument and notebook for …read more

Feel like taking a long walk, but can’t be bothered with carrying your drinks? Have no fear, this “Follow Me” Cooler Bot is here!
Really just a mobile platform with a cooler on top, the robot connects to smartphone via Bluetooth, following it using GPS. Making the platform involves a little woodworking skill, and an aluminium hub with a 3D-printed hub adapter connects the motors to a pair 6″ rubber wheels with a swivel caster mounted at the rear. A pocket in the platform’s base houses the electronics.
The Arduino Uno — via an L298n motor driver — controls two …read more
