THE BEST KIND OF HANDHELD GAMING IS HOMEMADE

[CNCDan] previously dabbled with Raspberry Pi CM4-powered gaming handhelds but was itching for something more powerful. Starting in May 2023, he embarked on building an Intel NUC7i5BNK-powered handheld dubbed NucDeck. As he goes over the feature list, it sounds like a commercially available console. A 1024 x 600 screen provides a good balance of fidelity and

PI ZERO FPV ROBOT USES TINY MOTOR & GEARS

We’ve seen plenty of first-person view (FPV) robots built using the Raspberry Pi Zero, but this one from [Shane] has an interesting twist: rather than directly driving the wheels from big motors, it uses small motors and gearboxes to drive the wheels, with some of the gears being 3D printed. [Shane] has posted the full details
