Hackaday Europe 2026: Project Gigapixel

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 – Building A Retro PC From Scratch

If you’re big into retrocomputing, you probably spend a lot of time chasing parts and machines on online classifieds or through local swap meets. But what if there was a different way to build a classic retro PC? What if you could put one together from bare chips, from the ground up?

[Jeroen Domburg] is no stranger to the pages of Hackaday. You might know him by his alias, [sprite_tm], under which he’s shared many projects, from miniaturizing old hardware to unearthing the secrets of undocumented commercial hardware. Now, he’s turning his considerable skills to figuring out how to build a retro PC in today’s world, and came to Hackaday Europe 2026 to show us all how it’s done.
