Buying Stuff from China – How Good Is It?
Anyone who likes playing with electronics knows about buying stuff from China. But how good is the stuff?
BUGS on my TV Screen – Digital On-Screen Graphics
Remember the old days when we longed for a better TV picture quality? Well, we got it. HDTV. And then the TV networks decided we also needed BUGS, or digital on-screen graphics. And, they can be really annoying.
DIY PCB – My First Attempt, Part 2
My 3D printer now does auto-leveling using a proximity sensor and an external control board. This DIY PCB article describes completion of printed circuit board used in this project.
DIY PCB – My First Attempt, Part 1
It’s amazing that after so many years with radio and electronics hobbies, I had never created a DIY PCB scratch. Oh, sure, I have used printed circuit boards made by others many times. These were either purchased commercially, or fabricated to my design. But it was time to make my own. So, here goes.
