Hackaday Prize Entry: A PC-XT Clone Powered By AVR

Posted on by

There is a high probability that the device on which you are reading this comes somehow loosely under the broad definition of a PC. The familiar x86 architecture with peripheral standards has trounced all its competitors over the years, to the extent that it is only in the mobile and tablet space of personal computing that it has not become dominant.

The modern PC with its multi-core processor and 64-bit instruction set is a world away from its 16-bit ancestor from the early 1980s. Those early PCs were computers in the manner of the day, in which there were relatively …read more

Hackaday Prize Entry: Device for Seismic Noise Analysis

Posted on by

Whenever there is an earthquake somewhere in the world, our TV screens fill with images of seismic data. Those news report graphics with simplified bite-sized diagrams that inform the masses, but usually get something wrong. Among the images there will invariably be one of a chart recorder drawing a significant earthquake trace on paper, which makes good TV, but is probably miles away from the state of the art in seismology.

We are not seismologists here at Hackaday, so it was extremely interesting to find [Michael D]’s project, Device for Seismic Noise Analysis. In it, he gives a basic primer …read more

Don’t Forget: Bring a Hack Munich is Tonight

Posted on by

If you’re in Munich, Germany this weekend and you’ve got a sweet hack to show off and a thirst for beer and/or good geeky company, then you’re in luck! Come join Hackaday at the muCCC for a Hackaday Prize Bring a Hack.

The location is Schleißheimer Str. 41, a short walk west along Heßstraße from the Theresienstraße U-Bahn. No reservation is needed, but it’d be swell if you’d let us know in the comments that you’re coming (or better yet, click the “join this event” button in the upper right of the event page) so that we have enough pizza …read more

Hackaday Prize Entry: Arduino Splash Resistant Toilet Foamer

Posted on by

There are some universal human experiences we don’t talk about much, at least not in public. One of them you’ll have in your own house, and such is our reluctance to talk about it, we’ve surrounded it in a fog of euphemisms and slang words. Your toilet, lavatory, john, dunny, khazi, bog, or whatever you call it, is part of your everyday life.

For his Hackaday Prize entry, [VijeMiller] tackles his smallest room head-on. You see, for him, the chief horror of the experience lies with the dreaded splashback. Yes, a bit of projectile power dumping leaves the old rump …read more

Friday Hack Chat: Chip Gracey from Parallax

Posted on by

Learn the ins and outs of multi-core microcontrollers as Chip Gracey leads this week’s Hack Chat on Friday 5/5 at noon PDT. Chip founded Parallax and has now been working for more than a decade on the Propeller 2 design, a microcontroller which has 8 and 16 core options.

When it comes to embedded development, most people think of a single process running. Doing more than one task at a time is an illusion provided by interrupts that stop one part of your program to spend a few cycles on another part before returning. The Propeller 2 has true parallel …read more

Hackaday Prize Entry: Hacker Calculus

Posted on by

Mathematics, as it is taught in schools, sometimes falls short in its mission to educate the pupils. This is the view of [Joan Horvath] and [Rich Cameron], particularly with respect to the teaching of calculus, which they feel has become a purely algebraic discipline that leaves many students in the cold when it comes to understanding the concepts behind it.

Their Hacker Calculus project aims to address this, by returning to [Isaac Newton]’s 1687 seminal work on the matter, Philosophiae Naturalis Principia Mathematica. They were struck by how much the Principia was a work of geometry rather than algebra, and …read more

Hackaday Prize Entry: High Speed Sampling For The Raspberry Pi

Posted on by

The Raspberry Pi has become a firm favorite in our community for its array of GPIOs and other interfaces, as well as its affordable computing power. Unfortunately though despite those many pins, there is a glaring omission in its interfacing capabilities. It lacks an analogue-to-digital converter, so analog inputs have to rely on an expansion card either on those GPIOs or through the USB port.

Most people remain content with simple ADCs such as Microchip’s MCP3008, or perhaps a USB sound card for low frequency moving targets. But not [Kelu124], he’s set his sights on something much faster. The original …read more

Friday Hack Chat: The Hackaday Prize

Posted on by

Did you know Hackaday is hosting a fantastic contest to build hardware and software? It’s true! The Hackaday Prize will award hundreds of thousands of dollars to Hackaday community members for building the coolest hardware designed to make a difference in the world.

The Hackaday Prize has many ways to enter, focusing on several themes throughout this year. We’ll be discussing that and opening the floor to questions. Tomorrow, Friday, April 28, at noon, Pacific time, we’re hosting a Hack Chat for the Hackaday Prize over on Hackaday.io.

Our guest host for this chat is [Alberto], creator of the project …read more

Hackaday Prize Entry: Brightenmacher

Posted on by

We have all at some point have made a flashlight. It used to be a staple of childhood electronics, the screw-in bulb in a holder, and a cycle lamp battery. If you were a particularly accomplished youthful hacker you might even have fitted a proper switch, otherwise, you probably made do with a bent paperclip and a drawing pin.

So you might think that flashlights offer no challenges, after all, how many ways can you connect a bulb or an LED to a battery? [Peter Fröhlich] though has a project that should put those thoughts out of your mind. It …read more
