Made by Martin DIY Nuclear Reactor Fusor
Martin never meant to spend a year and a half building anything nuclear. Another demanding task kept getting pushed aside, and the delay turned into something much larger. What began as avoidance became a complete fusor, a compact device that creates the conditions for atomic nuclei to fuse using straightforward electric fields instead of the enormous machines found in national labs.

Brian Watson has worked in games for more than four decades. He started at DMA Design on classics like Lemmings and later spent time at Sony on projects that included emulation work. During a talk at The Retro Collective museum in the United Kingdom, he brought along a prototype controller most people had never heard of and showed it to the room.

Dead 3D Printer Robot Focus Stacking
Alan of the MandicReally channel needed consistent, high-resolution close-ups of 3D printer nozzles and hot ends. Every tiny surface mark and wear pattern mattered for his Mandic Labs work, yet standard microscope shots left large portions blurred. Focus stacking solves that by shooting the same subject many times at different focus depths and merging the sharp areas later. Doing the job by hand quickly becomes impractical. The microscope’s own focus ring lacks the precision and repeatability required, and even small shifts in framing or angle ruin the stack.
