Liquid-Filled LED Bulbs: 360 Degree Light

I’ve been testing a new LED bulb called the HydraLux. These unique bulbs are filled with a clear liquid coolant (a non-toxic paraffin oil).

How To Build A Deep Bass System For $750

Tactile Transducers

In this article I will describe how to build a high-fidelity, bass-intensive sound system for under $1000. The secret ingredient of the system is the use of tactile transducers. These transducers effectively eliminate the need for expensive woofers or subwoofers. It’s an efficient method of producing deep, high-fidelity bass for a fraction of the usual cost. Many […]
