Hackaday Europe 2026: Half Quad, Half Blimp: Test. Fly. Survive.

July 23, 2026 by 7 Comments

A great many drones out there, whether homebuilt or store-bought, follow the same basic format. Four motors, some kind of controller, and a lithium-polymer battery supplying the juice to keep everything in the air. It’s a format that produces a remarkably capable air vehicle, suitable for everything from high-speed camera work to urban search and rescue.

With that said, the format does have its limitations. [Suryansh Sharma] has been working on alternative designs for fancy and interesting drones that are half quadcopter and half blimp, and he came to Hackaday Europe 2026 to tell us all about it.

Hackaday Europe 2026: Project Gigapixel

July 20, 2026 by 10 Comments

There was once a race to put out cameras with ever higher numbers of megapixels to snare customers eager to take the highest quality digital photos. These days, we know that things like optics, processing, and finer qualities of an image sensor are all very important beyond pure resolution. But, for a time, companies behaved as if megapixels mattered over all else.

But what if you could go farther—shooting not millions, but billions of pixels in a single image? That’s precisely what [Yannick Richter] came to Hackaday Europe to talk about, covering his Project Gigapixel build.

Hackaday Europe 2026 – Build A Cable Modem For Your Arduino

July 16, 2026 by 20 Comments

Even for those of us that are quite technically minded, we spend precious little time thinking about the cables that carry our signals and do all the important work we need them to do on a daily basis. A great deal of theory and engineering goes into making things like telephone lines and HDMI cables work, but we mostly just plug them in and get on with whatever we’re doing.

If this is your experience, you might find the Hackaday Europe talk from [Michael Wiebusch] to be particularly interesting. He dives into transmission line theory from an accessible standpoint, explaining how two disparate signals can go in opposite directions on the very same wire. Then he demonstrates the theory by building a cable modem… well, sort of!
