There’s something magical about a laser light show. Watching that intense beam of light flit back and forth to make shapes and patterns, some of them even animated, is pretty neat. It leaves those of us with a technical bent wondering just exactly how the beam is manipulated that fast. Wonder no more as [Zenodilodon], […]
We’ll all be familiar with Tic-Tac-Toe, or Noughts and Crosses, a childhood pencil-and-paper diversion which has formed the basis of many a coding exercise. It’s an easy enough task to implement in software, but how many of us have seen it done in hardware alone? That’s just what [Warren Toomey] has done using TTL chips, […]
Doom holds a special place as one of the biggest games of the 1990s, as well as being one of the foundational blocks of the FPS genre. Long before 3D accelerators hit the market, iD Software’s hit was being played on computers worldwide, and later spread to all manner of other platforms. [David Ruiz] decided […]
Parallel processing is an idea that will be familiar to most readers. Few of you will not be reading this on a device with only one processor core, and quite a few of you will have experimented with clusters of Raspberry Pi or similar SBCs. Instead of one processor doing tasks sequentially, the idea goes, […]
Humans like things that look like other things. A great example are faux LED tea light candles, with a plastic “flame” and flickering orange LED to recreate the effect of their waxy brethren. [gzumwalt] wanted to take the concept a little further, however, and got down to work. The design harvests the orange LED and […]
Many of us have seen an old bus for sale for a tantalizingly low price, and begun thinking about the possibilities. [EpiclyEpicEthan1] is someone who took the next step, bought the bus, and got to work converting it to an RV, with impressive results. The bus in question is a 2002 International RE3000, which in […]
“Amazing how with only the power of 3D-printing, two different computers, hundreds of dollars in CNC machinery, a lathe, and modern microcontroller magic, I can almost decorate a cupcake as well as a hyperactive ten-year-old.” We can think of no better way to sum up [Justin]’s experiment in CNC frosting application, which turns out to only […]
Take a dozen or so fish hooks, progressively embed them in plastic with a 3D printer and attach them to the feet of your hexapod and you’ve got a giant cockroach! A team of researchers at Carnagie Mellon University came up with this ingenious hack which can easily be copied by anybody with a hexpod […]
For whatever you have built, there is someone who has done it longer, and knows more about it. That is the basic premise of expertise, and for this year’s Hackaday Prize we’re rolling out with a series of mentor sessions. These are master classes that match up experts in product development with the people behind […]
Imagine a tub overflowing with bubble bath, except it’s a club dancefloor and music is pumping all night. This is what is known as a “foam party” — a wild and exciting concept that nonetheless many are yet to experience. The concept exploded in popularity in Ibiza in the 1990s, and foam parties are regularly […]
