After destroying one 555 timer IC (probably by a high voltage inductive spike) I decided to incorporate a PC817 #optoisolator in the #MOSFET driver circuit.

Today's experiment was to see the Miller plateau in a #MOSFET fed with a 1kHz square wave via a 1k resistor.
As the the edge of the square waves gets to the gate and the MOSFET turns on, the effective gate/drain and gate/source capacitances end up charging in the process. This causes the gate voltage to level off for a little while. The scope shows a plateau at 2.6V and about 72ns long in my breadboarded circuit with a 2N7000. I'm surprised at how easy it was to see this effect. #electronics

The processor-less circuit we use for such a trick at @craftoola is based on a #pir sensor and a #MOSFET. The sensor needs about 5V so we can either power it via #USB (as seen in the schematics), or with a double cr2032 battery case (which is what I used). You can then use a series of 2 3V LEDs (I used 2 noodle LED chains). #electronics #tip

Use my Raspberry Pi Pico to switch between them rapidly. I figure 0.01 of a second illumination followed by 0.04 of a second darkness should make it look like they're all illuminated. Rather than using transistors to drive relays I figure a set of mosfets might do the job better. Here's the thing though I need some help. My electronics is virtually non-existent. The lights are 12v, 5A. Which mosfets will handle that and what resistor etc do I need?

I wonder if "THEL" (King of Hifi Marketing Talk ;-) was/is known outside of Germany ?
