The Invisible Killer of GPUs in Humid Environments: A Comprehensive Guide to Prevention and Repair of Circuit Board Oxidation

The continuous rain of the plum rain season, the seepage of walls during the humid days in the south, and the condensation caused by the temperature difference between air-conditioned rooms and the outdoors… These seemingly ordinary humid scenarios are quietly launching “invisible attacks” on computer hardware, especially on precision GPUs. Circuit board oxidation, as a … Read more

Top 10 Common Sensors in IoT

by

In IoT (Internet of Things) scenarios, sensors are ubiquitous and an indispensable part of the IoT. The first thermostat was introduced in the late 1880s, and infrared sensors began appearing in the late 1940s. IoT and its corresponding Industrial IoT (IIoT) are taking the use of sensors to a new level. Broadly speaking, sensors are … Read more

Creating a Music Keyboard with Arduino

Compared to instruments like trumpets and flutes, electronic keyboards are easier to understand and operate. If we use a USB keyboard as the instrument keys, we can create the simplest keyboard instrument. To achieve this goal, we need to solve two problems: sound generation and parsing USB keyboard data. ·Sound Generation First, we need a … Read more
