DRY ICE vs ELECTRONIC COOLING!

From Tech Ingredients. We demonstrate why TECs or Peltier devices have a lower temperature limit. We also describe how low temperature liquid baths are set up in a lab, why they can be dangerous and even though we drop the “hot” side of a TEC to “only” -43C with a small amount of dry ice,…

World’s Second Best Speakers!

From Tech Ingredients. We construct a pair of large Voigt speakers. I explain the principles behind ported, transmission line and horn based loudspeakers, demonstrate these speakers in our anechoic chamber and use constrained layer damping to build an enclosure that is superior to commonly used MDF.
