On September 16, 2025, Tektronix officially announced the 7 Series DPO Oscilloscope, opening a new generation of ultra-high performance oscilloscopes. This is a series of oscilloscopes designed to provide the lowest noise, highest ENOB, and support bandwidth up to 25 GHz right from the launch.

In the technical world, especially those who work in mechanics, construction or material research, the concept of strain gauge is probably not unfamiliar. One of the devices that plays an extremely important role in measuring, analyzing and controlling the quality of construction and products. Many people who are new to it often think it is complicated at first, but in fact, if you understand the principles and how to use it, the strain gauge is quite friendly and easy to apply in many situations.

Many people who are new to aquascaping often wonder about the TDS index in the tank, not knowing what level to keep it at and what to do when it is too high or too low. After a long time of being involved in this hobby, I have gained some experience and want to share it for your reference.

In a cup of coffee, more than 98% is water. It sounds simple, but this water determines a lot of the flavor. The remaining less than 2% is the coffee dissolved in.
