At the end of August I made the trip to Hebden Bridge to give a talk at OSHCamp 2019, a weekend of interesting stuff in the Yorkshire Dales. Instead of a badge, this event gives each attendee an electronic kit provided by a sponsor, and this year’s one was particularly interesting. The RC2014 Micro is […]
Build something cool and pick up new skills from the workshops at the Hackaday Superconference. But decide right now, workshops will sell out and tickets to the conference itself are nearly gone. You must have a Superconference ticket in order to purchase a workshop ticket; buy one right now if you haven’t already. We think this […]
Us: “I’ll take Retro style displays we absolutely have to have for $200, Alex.” Trebek: “This nixie tube is unlike any conventional tube you’ve seen before, handbuilt and NOT numbers or letters.” Us: “What is FriendlyWire’s new logo tube?” Trebek: “Heck yeah.” Nixie tubes are the vacuum technology that manages to do far less than […]
An Elegoo Mars DLP resin 3D printer, straight to my doorstep for a few hundred bucks. What a time to be alive. Resin-based 3D printers using stereolithography (SLA) and especially digital light processing (DLP) are getting more common and much more affordable. Prosumer-level options like Formlabs and the Prusa SL1 exist, but more economical printers […]
With the price and availability of components these days, it’s easier than ever to throw a whole pile of LEDs at a build and get them flashing away. The hard part is doing it well. [Amy Goodchild] is an artist, and has a knack for producing rather beautiful LED projects. The When in Dome installation […]
A smartphone in 2019 is an essential piece of everyday equipment. Many of you are probably reading this page on one, and it will pack a very significant quantity of computing power into your hand. Pocket computing has a long history stretching back decades before the mass adoption of smartphones though, and Paleotronic has an […]
Most people have at least seen those cheap component testers you can buy on the Chinese websites for $10 or so. If you haven’t seen them before, they usually have some kind of multi pin socket. You put a component in the socket and it will identify — with a push of a button — […]
One of the great things about ham radio is that isn’t just one hobby. Some people like to chit chat, some like to work foreign countries, some prepare for emergencies, and there are several space-related activities. There are hundreds of different kinds of activities to choose from. Just one is moonbounce, and [Ham Radio DX] […]
3D printing is a great way to create complex geometric forms. However, it can be very slow, and parts may lack strength compared to other alternatives. There are other ways to take advantage of this technology however, as shown in the build of this tidy voronoi lamp. The lamp is so-called for its voronoi-patterned base, […]
If you were tasked with designing a color video monitor, it’s pretty clear how you’d go about it. But what if you’d been asked to do so 20 years ago? Would it have been a cut and dried from an engineering standpoint? Apparently not, as this hybrid LCD-CRT video monitor demonstrates. We’d honestly never heard […]
