Every time I plug my Logitech speakers into the wall they play gospel music by rainbowsunshine1in electronics

[–]spainguy 4 points5 points ago

Sounds like the input stage is rectifying a AM radio signal, like an an untuned crystal set,

Something like these might work

If they don't you will need to get inside the speakers and put an RF filter in the circuit(s), (not recomended for newbies)

Indian state to let forest guards shoot poachers on sight: Maharashtra government says killing poachers will no longer be considered a crime after eight tiger deaths in the state this year. by vegetable_offenderin worldnews

Power ratings of power supplies and amplifiers? by petematein electronics

[–]spainguy 2 points3 points ago

How is the peak rating defined?

Usually Watts at a specific distortion + marketing factor

500W momentarily

It's a can of worms measurement, dependent on the storage capacitors in the ( linear) power supply.

Basically the only real rating is true RMS

Europe's worst fear: Spain and Greece spiral down together by syukin worldnews

No, badly built, you can hear a person fart next door, thermally crap, built to the lowest possible standards.

I was lucky and managed to sell mine.

Most are built out of shit and covered in marble. ( in my area anyway)

If somebody a few feet away can hear your stomach "growling" through all the fat and muscle of your body, does that mean it has to be deafeningly loud INSIDE your body? Is there an actual measurement in dB that can be made? by Aeon_fuzzin askscience

An industry standard audio filter for making measurements

lol, /r/electronics is midway between 555today and arduino++

Not exactly "scientific"

Probably MSF then

Radio controlled clock jammer by duded1000in electronics

[–]spainguy 4 points5 points ago

That's probably WWV, so you would have to simulate the signal, but the clock probably only update a couple of times a day. Jamming the WWV signal could be highly expensive for other people in your vicinity that use it,

Why are tantalum capacitors marked on the positive side, while diodes and electrolytics are marked on the negative side? by dammitdin ECE

[–]spainguy -2 points-1 points ago

The ink they use for the marking is electropositive and would serious ESR problems if it was used on the negative terminals

Elizabeth Warren urges supporters to press Congress to pass a new Glass-Steagall law that would separate “high-risk investment banks” from more traditional banking. “It would allow Wall Street to take risks, but not by dipping into the life savings and retirement accounts of regular people,” by AdamVR4in politics

Redefine Wall Street/banks as being gay or having a vagina, suitable laws will soon be in place

Could use some advice regarding signal reflection. by madprgmrin ECE

[–]spainguy 2 points3 points ago

I had a similar SPI problem, to 7 segment LED drivers, 80 leds at 30mA each, (max 2.4Amps) The problem was ground bounce when the /OE line changed, to PWM the STP16cps05. Termination of the cables didn't help.

The cure was to add 22uF across each LED display.

A scope is essential for this sort of problem
