Genmitsu Z5-1 fiber laser engraver review

Sainsmart Z5-1 Fiber laser review

Good day. Karl here. Today I would like to share my experiences with the Genmitsu Z5-1 fiber laser engraver in this review. What is an infrared Galvo laser? A fiber laser is also known as an infrared Galvo laser. Let’s break this combination of words down. Infrared is first. Up to this point, I have reviewed several powerful blue diode lasers for the site. All of them have had 455nm wavelength lasers. In contrast, the Genmitsu Z5-1 laser we are looking at today has a 1064nm wavelength that is outside of the visible spectrum. With infrared, we can mark different materials. Notable plastics and metals are easy to mark with this laser. Galvo is next and was a term I was not familiar with. “Galvo” is a condensed form of “galvanometer.” It’s an electromechanical device used for precise mirror or optical element control in laser and optical systems. Galvanometers are […]

AirGradient ONE Kit Review – An open-source indoor air quality monitor

airgradient one ready to work

The product we are reviewing today is the “AirGradient ONE” air quality monitor kit which is an updated version of the earlier AirGradient air quality monitor. The device is equipped with sensors from Sensirion and Plantower, allowing it to measure many air quality parameters such as CO2, PM2.5, TVOCs, NOx, temperature, and humidity. It is an indoor air quality monitor that is both open-source software and open hardware. This means that the Arduino source code, schematic diagrams, PCB, and 3D models of the enclosure are available to developers. AirGradient ONE DIY Kit Unboxing The device was packaged within a cardboard box, with a greeting card from the manufacturer. The card features a QR code linking to a webpage with the installation guide. Since I requested the Kit version (there’s also a fully assembled model), some sensors were not pre-assembled and they were well-packaged in separate seals. The main PCB was […]
