Collaborate Disseminate
[David Johnson-Davies] has a lofty goal of building a small device to give to younger hackers on a semi-yearly basis. So this last year, he designed and created The Number …read more Continue reading A Number Maze For Younger Hackers
Inspired by a prank tweet, [Sam Ettinger] endeavored to create an SMD seven-segment display. The NanoRaptor NanoSegment implements a panel of seven-segment display modules sized at “0806” each or just …read more Continue reading Nano-Sized 7-Segment LED Display on a Surface Mount Module
We’re suckers for a nice seven-segment LED display around these parts, and judging by how often they seem to pop up in the projects that come our way, it seems …read more Continue reading Quick Tip Improves Seven-Segment LED Visibility
Have you ever looked at the time, and then had to look again because it just didn’t register? This phenomenon seems more prevalent with phone timepieces, but it’s been known to happen with standard wall clocks, too. This latest offering in a stream of unusual clocks fashioned by [mircemk] solves …read more

In an era where we can see the current temperature with just a glance at our smartphones, the classic “Time and Temp” gadget sitting on the desk doesn’t have quite the same appeal. The modern weather fanatic demands more data, which is where this gorgeous full-day temperature display from [Richard] …read more
[Sean Hodgins] has a knack for coming up with simple solutions that can make a big difference, but this is one of those “Why didn’t I think of that?” things: addressable seven-segment LED displays.
[Sean]’s design is basically a merging of everyone’s favorite Neopixel RGB LED driver with the ubiquitous seven-segment display. The WS2811 addressable RGB driver chip doesn’t necessarily have to drive three different color LEDs – it can drive three segments of the same display. With three of the chips on a single board, all seven segments plus the decimal point of a display can be controlled over …read more

In our time here at Hackaday, we have seen many display builds, but this one from [Brian Lough] has to be a first. He’s created a 7-segment display made from shoelaces, and it works rather well.
Before you imagine the fabric cords you’re used to with your trainers, it’s worth explaining that these aren’t shoelaces in the traditional sense, but transparent light pipe taken from commercially available light-up shoelaces. He’s created a 3D-printed frame with receptacles for each end of the light pipe sections he’s used as segments, and spaces for addressable LEDs on the rear. He makes no bones …read more
Continuous self-affirmation is a vital component to the modern lifestyle. Of course you know the world loves you, but exactly how much do they love you? Checking your phone every few minutes to see if you’ve gained any followers is gauche, and perhaps more to the point, doesn’t let you show off when you’ve got visitors over. In the modern era, the up-and-coming social media star needs a stylish way to display just how popular they are for the world to see.
That’s the idea behind this very slick social media counter created by [Becky Stern]. Built into a standard …read more

There’s something about clocks — sooner or later, every hacker wants to build one. And we end up seeing all kinds of display techniques being used to show time. For the simplest of builds, 7-segment display modules usually get dug up from the parts bin. If you have a bunch of “smart” LED’s (WS2812’s, APA102’s), then building your own custom 7-segment modules isn’t too difficult either. [rhoalt] had neither, but he did have several 8 LED Neopixel rings lying around. So he thought of experimenting with those, and built a ‘Binoctular’ LED clock which uses the Neopixel rings as 7 …read more
