Do you use a Canon EOS R mirrorless camera? From wide-angle to telephoto, these are the best lenses we've tested for the platform. Images, and the devices that capture them, are my focus.

How do you pick the best Canon printer from its huge range of options? Our guide will help you find the right one for you When you purchase through links on our site, we may earn an affiliate ...

But if you want something that offers cardio with some resistance training, opt for a mini stepper. Fortunately, there's one on sale at Amazon and it costs less than $50. For a limited time ...

This library should support any Arduino-compatible board, including the Pololu A-Star controllers. The HighPowerStepperDriver library supports Pololu's High-Power Stepper Motor Driver 36v4. Before ...

Abstract: It is well known that inclined sidewall scattering structures can improve the light extraction efficiency (LEE) of micro deep ultraviolet (DUV) light-emitting diodes (LEDs). However, ...

在超宽带隙半导体领域，研究者们正致力于开发具有超高增益的深紫外（DUV）光电探测器，以期达到与光电倍增管（PMT）相媲美的性能。这些探测器对于200-280纳米波长范围内的日盲检测和通信至关重要，因为它们能够提供高灵敏度、高速度、高光谱选择性、高 ...

To progress towards the goal of realizing large aperture meta-optics with commercially viable fabrication techniques, this work also presents a version of the 2 cm eyepiece doublet that compatible ...
