layer effects

Chess player John Bartholomew plays opponents rated below 1000 on Chess.com and comments on optimal strategy and typical mistakes at that level. It is part of his Climbing the Rating Ladder series.

A roughly three-hour screen recording of designing a barebones STM32F4 board in KiCad, covering schematic, four-layer layout and routing, USB and a buck converter. It ends with ordering manufacture and assembly through JLCPCB.

A 100-minute tutorial from Phil's Lab on designing an STM32-based 'black pill' PCB in KiCad 6. It covers schematic capture, two-layer layout and routing, USB, and sending the board for manufacture and assembly.

Mathologer shows a simple idea, the commutator, that lets anyone who can solve the first layer design their own full Rubik's cube solution. The same idea carries over to other symmetric twisty puzzles such as the Megaminx.

The first part of a ShaderToy live-coding series that lays the groundwork for The Drive Home, a rainy night-traffic shader. It covers basic setup and builds toward rain and bokeh effects.

Tech Ingredients builds a pair of large Voigt speakers and explains ported, transmission line and horn designs. It tests them in an anechoic chamber and uses constrained layer damping for the enclosure.
