PC World ☛ Raspberry Pi 5 gets a superpowered 16GB model for the first time
So, what’s the reasoning behind the upgrade? According to Raspberry Pi CEO Ebon Upton, it’s to make room in the memory for “heavyweight distributions like Ubuntu” and more demanding applications such as computational fluid dynamics and (sigh) large language AI models. Micron was able to supply the Raspberry Pi company with the necessary components, and here we are.

Hackaday ☛ Sheet Metal Forming With 3D Printed Dies
Sheet metal is very easy to form, including the pressing in of intricate shapes with dies and a hydraulic press, but the dies themselves are slightly harder to come by. What if we could 3D print custom dies to stamp logos and more into sheet metal? This is the premise of a recent video by the Stick Shift Garage channel on YouTube in which dies are printed in PLA+ (solid infill) and used to stamp 1 and 2 mm thick sheet metal with the channel’s logo.
