The Dutch word for sundial, zonnewijzer, can be literally translated into “Sun Pointer” according to [illusionmanager] — and he took that literal translation literally, building a reverse sundial so he would always know the precise location of our local star, even when it is occluded by clouds or the rest of the planet. The electronics […]
There are still a few days before the doors open on this year’s Hackaday Supercon in Pasadena, but for the most dedicated attendees, the badge hacking has already begun…even if they don’t have a badge yet. By referencing the design files we’ve published for this year’s Communicator badge, [Thomas Flummer] was able to produce this […]
Pong was one of the first video games to really enter the public consciousness. While it hasn’t had the staying power of franchises like Zelda or Call of Duty, it nonetheless still resonates with gamers today. That includes [Arnov Sharma], who put together this neat handheld version using modern components. An ESP32 development board serves as the brains […]
Despite initial interest in the 1990s and early 2000s, palmtop computers never really took off. Realistically most consumers were probably satisfied enough with smartphones as they became more widely available, but those of us who would prefer a real keyboard on our mobile devices are still feeling the pain. Today there are still a few […]
ARM single-board computers like the Raspberry Pi are great for some applications — if you need something that’s energy efficient or can fit into a tight space, they’re tough to beat. But sometimes you’re stuck in the middle: you need more computational muscle than the average SBC can bring to the table, but at the […]
With as cheap and versatile as RTL-SDR devices are, it’s a good idea to have a couple of them on hand for some rainy day hacking. In fact, depending on what signals you’re trying to sniff out of the air, you may need multiple interfaces anyway. Once you’ve amassed this arsenal of software defined radios, […]
Like many creative individuals who suddenly find themselves parents, [Marta] wanted to make something special for his children to play with. Anybody can just purchase an off-the-shelf electronic toy, but if you’ve got the ability to design one on your own terms, why not do it? But even compared to the fairly high standards set […]
Over the years we’ve seen countless ways of displaying the current time, and judging by how many new clock projects that hit the tip line, it seems as though there’s no end in sight. Not that we’re complaining, of course. The latest entry into the pantheon of unusual timepieces is this ESP32-powered desk clock from […]
About a year back, [BogdanTheGeek] found himself in need of a new case for this TS100 soldering iron. Unfortunately, while the product is often billed as being open source friendly (at least in the firmware sense), he was surprised to discover that he couldn’t find the detailed dimensions required to 3D print his own replacement […]
Over the years we’ve seen several attempts at adding Internet connectivity to the lowly wired doorbell. Generally, these projects aim to piggyback on the existing wiring, bells, and buttons rather than replace them entirely. Which invariably means at some point the AC wiring is going to need to interface with a DC microcontroller. This is […]
