glibg10b, to askelectronics in Microvawe transformer spotwelder. Is there a way to improve it?

I believe the voltage is still high

I believe there are devices that can measure such things

Isn’t that Rey from the sequels?

glibg10b, to piracy in For those who pirate songs, how do you discover new music?

I use the ReVanced version of YouTube Music (no ads, high quality music). If I find a song that I like, I download it in FLAC format from one of the sites in the megathread

Why not just save the post?

  • The Art of Electronics (book)
  • LTspice (simulation software)
glibg10b, to askelectronics in Do AA Battery Holders - Connected in Parallel so still 1.5V - Exist?

AA batteries are typically non-rechargeable, so there’s not much of a need for putting them in parallel

glibg10b, to electronics in I need a new bench power supply

Lab equipment does tend to be expensive

Are you using the BJT to create an AC signal? If so, how?

glibg10b, to askelectronics in What type of connector is this ?

SAS

glibg10b, to askelectronics in Continuous operation of a general purpose relay?

With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery?

Current flows from high to low voltage, but the battery is at a lower voltage than the supply. Check the diode’s datasheet for the reverse current at the voltage that would be across it. It should be negligible

Here’s an example from my notes:

glibg10b, to askelectronics in Small fan switch sanity check.

It essentially turns into a small generator while spinning down

Kind of like an inductor?

glibg10b, to askelectronics in Small fan switch sanity check.

The transistor is a 2N4401. From the datasheet, VBE(sat,max) = 1.2 V and hFE(min) = 20, so it could drive ~60 mA in the worst case

The maximum ICE is 61.76 mA in the worst case, so I’d say you’re good
