Just before this issue went to press, I received a product safety complaint via NSW Fair Trading, alleging that _Silicon Chip_ magazine is unsafe. Apparently, this is because we explain how to build mains-powered devices, such as the Touch & IR Remote Control Dimmer featured in February and March this year. ... http://www.siliconchip.com.au/Issue/2019/April/Nannies+want+...

we have an inverting opamp as AC amplifier with gain 100 or 1000 in a shielded aluminum box. BNC as input and output. Using chopped light and measuring noise on top of a signal with a lockin amplifier. I am wondering why different ops behave differently. We had it on the table so that input and output BNC crossed each other at ca. 90°. Not optimal, I know, so we rotated the al

We're all gonna die. "Earth?s magnetic field is getting significantly weaker, the magnetic north pole is shifting at an accelerating pace, and scientists readily admit that a sudden pole shift could potentially cause ?trillions of dollars? in damage. Today, most of us take the protection provided by Earth?s magnetic field completely for granted. It is essentially a colossa

I wanted to make a physical device to emulate a long transmission line. This particular line has lots of C, I know the R and can guestimate the L. So I built a lumped line using T sections, 10 Rs, 10 Ls and 9 Cs to ground. So far so standard. It didn't perform very well, and I think part of the reason was the impedance being too large - dominated by the first R - so limiting the pow...
