Cutting-edge diy projects
d.i.y. CO2 Lasers and related equipment and materials.
I just posted at www.diyPhysics.com detailed instructions on the construction of a 250 kV DC high-voltage power supply. Although my hack for switching the polarity (referenced to ground) is simple, I am very surprised that I’ve never seen it elsewhere!
In my prior post I told about components in my CO2 laser’s RF power supply becoming unsoldered when they overheated. After the repair, I needed some way of retuning the RF output stage for maximum laser output. This motivated me to build the power sensor shown in the picture above. Continue reading
I was thinking about buying a laser engraver/cutter for home, but after retrofitting for CNC the Micro-Mark mini mill that my wife gave me for my birthday, I figured that I could simply add a CO2 laser to the X2 mini mill.
Before describing the mod, I figured you would want to see some results. Here is a YouTube video of my X2 mini-mill laser engraver in action: Continue reading
