One of the ways people use FPGAs is to have part of the FPGA fabric hold a CPU. That makes sense because CPUs are good at some jobs that are hard to do with an FPGA, and vice versa. Now that the RI…

The history of aviation is full of notable X-Planes, a number of which heralded in new generations of flight. The Bell X-1 became the first aircraft to break the speed of sound during level flight …

We’ve reduced printed circuit board design to practice so much that we hardly give a thought to the details anymore. It’s so easy to bang out a design, send it to a fab house, and have …

The latest entry in the fan favorite franchise Pokémon saw release earlier this month alongside a particularly interesting controller. Known as the Poké Ball Plus, this controller is able to contro…

If you’re building a computer, your options are nearly limitless. You can get a motherboard with red LEDs, with blue LEDs, green LEDs, or if you’re feeling spendy, RGB LEDs. You can get…

On November 10th, [Theodore Rappaport] sent the FCC an ex parte filing regarding a proposed rule change that would remove the limit on baud rate of high frequency (HF) digital transmissions. Accord…

Ah, the simple pleasures of a bike ride. The rush of the wind past your ears, the gentle click of the derailleurs as you change gears, the malignant whine of the dual electric jet turbines pushing …

Hackaday is going to be at the 35th annual Chaos Communication Congress (35C3), December 27th – 31st, and we’re putting together an assembly. If you’re coming to 35C3, come join u…

We’ve talked about transparent wood before. However, the process can be difficult to get just right. [NileRed] recently posted a video with very detailed instructions on how he’s doing …

It is a good bet that if you look around you, you’ll be able to find at least one smoke detector in sight. If not, there’s probably one not too far away. Why not? Fires happen and you&#…

There’s a battle going on in academia between the scientific journal publishing companies that have long served as the main platform for peer review and spreading information, and scientists …

The most awesome things about having a 3D printer is that you can create almost anything which includes parts for the 3D printer itself. Different materials give power to your imagination and allow…

Bill Gross is one of the great heros when it comes to technology incubators. Twenty years ago, he founded Idealab, a business whose business plan is to create more businesses. This started out with…

Sometimes, traveling the internet feels a little like exploring an endless cave system looking for treasure. Lots of dark passageways without light or life, some occasional glimmers as you find a s…

Building an LED matrix is a fun project, but it can be a bit of a pain. Usually it starts with hand-soldering individual LEDs and resistors together, then hooking them up to rows and columns so the…

We always think that crossing the Atlantic in a blimp would be very serene — at least once they put heaters on board. The Hindenburg, the R-101, and the Shenandoah put an end to the age of th…

Drone racing comes in different shapes and sizes, and some multirotor racers can be very small indeed. Racing means having gates to fly though, and here’s a clever DIY design by [Qgel] that u…

We’ve seen our fair share of soft silicone robots around here. Typically they are produced through a casting process, where molds are printed and then filled with liquid silicone to form the …

Here’s an interesting thought: it’s possible to build a cubesat for perhaps ten thousand dollars, and hitch a ride on a launch for free thanks to a NASA outreach program. Tracking that satellite al…

Right now, we’ve got artistic PCBs, we’ve got #badgelife, and we have reverse-mounted LEDs that shine through the fiberglass substrate. All of this is great for PCBs that are functional…
