# Summary of IRC Log from February 7, 2016

* A user shared their progress on creating a PCB-based display that uses the fluorescence properties of solder mask under UV light, where heat from high current (around 5A) changes the fluorescence characteristics, creating a visual effect that can be controlled through a matrix of pads.

* The user is designing a 15x15 pixel matrix using an ARM microcontroller (STM32F302R6T6) with 50 I/O pins, marking their first use of an ARM chip outside of a development board.

* A link was shared to a soft pneumatic actuator research project at Shanghai Jiao Tong University, showing a robotic arm system controlled by motors and pulleys in the base.

* Ben Goertzel's hedge fund (Aidyia) was mentioned, with discussion noting that similar AI-driven financial ventures were part of his previous company Webmind's business model.

* A user mentioned Raman spectroscopy (initially mistyped as "riehmann spectroscopy"), suggesting a discussion about spectroscopic techniques.

* Hannah Arendt's philosophical work "The Human Condition" was briefly referenced, though without detailed discussion of its content.
