Microphones: An abundance of options for capturing tones
Having just covered the topic of speaker construction (specifically as it relates to in-ear headphones), both in one of last month’s blog posts and one of the prior month’s teardowns, I thought now would as good a time as any to tackle the…
Resolution explained for magnetic angle sensors
Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders, a device providing the angle of a magnet attached to a mechanical shaft under a digital form. Resolution is a key…
Hot resistance versus cold resistance
Incandescent lamp filaments have ratios of hot resistance versus cold resistance that really startled me even though I thought I knew all about such things. It turns out I did not know “all about” and the consequences of my ignorance were…
