# Key Points from IRC Discussion

• Users debated the merits of ranking scientists through platforms like "Superstars of Science," questioning whether such rankings are appropriate for scientific achievement, with some suggesting educational science trading cards as a better alternative to Pokémon for teaching children about scientists like Susumu Tonegawa.

• A technical discussion revealed how LCD monitor specifications are often misleading, particularly "grey-to-grey" response times, with the explanation that display latency issues stem primarily from firmware and controller logic implementation rather than panel technology itself.

• Alternative hydrogen extraction methods were compared, including a radio frequency technique for extracting hydrogen from saltwater and a suggestion to use NaAlH4 with water drip as a potentially faster production method.

• DIY eye tracking solutions were explored, with recommendations to modify webcams by removing IR filters and using developed analog film as a visible light filter, potentially leveraging OpenCV for the software framework.

• Affordable 3D scanning approaches were shared, including a $10 webcam with line laser setup, with specific recommendations for green lasers due to Bayer pattern cameras having more green pixels, and software solutions like the David Laser Scanner (http://www.david-laserscanner.com/).

• Participants discussed fabrication lab equipment rates ($30-50/hour) for advanced technologies like gas chromatography, plasma etchers, and electron microscopes, noting these were reasonable prices for testing fluidics despite costs accumulating quickly.

• A resource listing ultrasound-guided focused ultrasound manufacturers was shared (http://www.fusfoundation.org/MRgFUS-Overview/device-manufacturers), featuring companies like EDAP-HIFU, HAIFU, and Histosonics.
