There it was, after twenty minutes of turning the place over, looking through assorted storage boxes. A Thinwire Ethernet network. About the smallest possible Thinwire Ethernet network as it happen…

When the Raspberry Pi first appeared there was some excitement among Raspberry Jam attendees at the prospect of a computer with a video output on a board small enough to be concealed inside a TV. B…

A telescope isn't an unusual thing to own if you are technically inclined. You might have even made one, at some point. However, despite improvements in optical technology and computer aiming devices,...

Researchers at MIT have used 3D printing to open the door to low-cost, scalable, and consistent generation of microencapsulated particles, at a fraction of the time and cost usually required. Microe...

[Facelessloser] is interested in glanceable information. Glancable devices are things like your car's dashboard, your wristwatch, or widgets on a smartphone lockscreen. The glanceable information di...

Amateur radio is an eclectic hobby, to say the least. RF propagation, electrical engineering, antenna theory – those are the basics for the Ham skillset. But pneumatics? Even that could come …

Millions of premature babies are born every year, and more than a few of these births occur hours away from any hospital with a NICU. [Manoj]'s entry for the Hackaday Prize is a simple, but very usefu...

LISP is a polarizing language. Either you love it or you hate it. But we’ll put aside our personal preferences to bring you a good hack. In this case a LISP environment running on an ESP8266.…

Hanging plotters, or two steppers controlling a dangling Sharpie marker on an XY plane, are nothing new to our community. But have you ever thought of trading out the Sharpie for a wood router bit …

Unless you've been living under a high voltage transformer, you've heard about the potential for Samsung's latest phone, the Note7, to turn into a little pocket grenade without warning. With over 2.5 ...

Most people wish they were more productive. Some buckle down and leverage some rare facet of their personality to force the work out. Some of them talk with friends. Some go on vision quests. There…

Researchers recently observed negative refraction of electrons in graphene PN junctions. The creation of PN junctions in graphene is quite interesting, itself. Negative refraction isn’t a new…

Want to climb a wall like Spiderman? No problem – just whip up a climbing rig with microwave oven transformers. And find a steel building. And rewrite the canon so that Peter Parker is bitten…

You’ll have to dig out your French dictionary (or Google translate) for this one, but it is worth it. [Nicolas Giraud] has been experimenting with ways to use a webcam to detect the number of…

If you watch the old original Star Trek, you’ll notice that the computers on board the Enterprise don’t look much like our computers (unless you count the little 3.5 inch floppies that …

The theme of the last Hackaday Prize challenge was Assistive Technologies, and with this comes technical solutions for people with severe motor restriction. One of the best we've seen is a device desi...

Even though [Stefan] sent in this link with the heading "Another Sunrise Alarm Clock", it's anything but plain. Sure, from the outside it looks like a simple and refined design, but the story of getti...

Do you remember the early days of consumer wireless networking, a time of open access points with default SSIDs, manufacturer default passwords, Pringle can antennas, and wardriving? Fortunately ou…

We all know feature creep can be a problem in almost any project. A simple idea can often become unusable if a project’s scope isn’t clearly defined in the beginning. However, the oppos…
