Athletes of every age receive a lot of blows to the head. After a few years of this and a lot of concussions, symptoms similar to Alzheimer's can appear. For his Hackaday Prize entry, [Mihir] wanted ...

A small LCD screen can be extremely helpful with small microcontroller projects. Not everything needs to communicate to a fancy server using an ESP8266. However, if the simplicity of the character …

A few years ago, [Kingpin] a.k.a. [Joe Grand] (A judge for the 2014 Hackaday Prize) designed the most beautiful electronic prank ever. The BSODomizer is a simple device with a pass-through connection ...

Anyone who owns their own pool knows it’s not as simple as filling it up with water and jumping in whenever you want. There’s pool covers to deal with, regular cleaning with the pool va…

One of the takeaway ideas that we got from BEAM robotics was the idea that the machine itself, rather than tons of processing power, can do a lot. Your hand affords gripping, and humans have made a…

If you haven’t heard, retrogaming is a thing. 40-somethings are playing the games of their youth alongside millennials who are just discovering these classic games. There are even folks devel…

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a …

The things Hackaday readers come up with and post over on Hackaday.io never cease to amaze us. If you've never checked it out, be careful — you can easily spend hours (or weeks) of your life just s...

How many instructions does [agp.cooper’s] computer have? Just one. How many strip boards does it use? Apparently, 41 five 41-track boards. While being one shy from the answer to life, it is s…

[Sam Barrett] is doing something that is sorely needed. He’s doing real materials research on FDM parts. There’s nothing wrong with the rough experiments like hanging a 1 L bottle of wa…

With more and more research in the field of autonomous robotics, new methods of locomotion are coming on the scene at a rapid pace. Forget wheels and tracks, forget bi-, quad-, hexa- and octopods, and...

[Drygol] found himself with six Commodore 64's in various states of disrepair. Because batch work is often more efficient, he detailed the process of restoring all of them in parallel in this one-, t...

One click on the wrong YouTube link, and one sleepless night after being introduced to virtual pinball, and [Sascha Rossier], aka Swiss hip-hop rapper [Der Lügner], was at work on his own design. You...

Many years ago [ScorchWorks] built an electrical-discharge machining tool (EDM) and recently decided to write about it. And there’s a video embedded after the break. The build is based on the…

[KC Budd] wanted to make a car-tracking GPS unit, and he wanted it to be able to phone home. Adding in a GSM phone with a data plan would be too easy (and more expensive), so he opted for the hacke…

The Starship Enterprise (no bloody A, B, C, or D) recently got a makeover. It was donated to the Smithsonian, and the workers at the Air and Space Museum took it apart and put it back together. W...

One of the most common problems in the world of microcontrollers is running out of resources. Sometimes it's memory, where the code must be pared down to fit into the flash on the microcontroller. Oth...
