There are a number of ways to efficiently and elegantly limit an LED’s brightness, but [Tommy] found that using a light pipe or diffuser can integrate better with a device, …read more Continue reading 3D Printed Light Pipe Turns Overly-Bright LED Into Design Harmony
It may not be the most efficient way to steal data from an organisation, let alone the most practical, but researchers at Ben-Gurion University in Israel have once again detailed an imaginative way to exfiltrate information from an air-gapped computer….

Most of us are aware that charlieplexing can drive a large number of LEDs from a relatively small number of I/O pins, but [David Johnson-Davies] demonstrates adding another dimension to that method to create individually controlled PWM outputs as well. His ATtiny85 has twelve LEDs, each with individually-set brightness levels, …read more
