Comparison of a 5W laser, 10W, and 20W diode laser. All these machines have their pros and their cons, but this is a quick ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...

Where there is power there is heat, and where there is heat there is often a need to sense temperature (the most widely sensed physical variable). What we call temperature is our measurement of a ...

[Jeshua Lacock] from 3DTOPO owns a large-format CNC (4’x8′, or 1.2×2.4 m), that he strongly feels is lacking laser-cutting capabilities. The frame is there, and a 150 W CO2 laser tube has been sitting ...
