Not grounded

So what

Good stuff.

AI slop 😢

Hi electro university and everyone. Can not the capacitor be fault/continuity tested whilst still attached to PCB please, I got a blood pressure monitor that is not working, I continuity tested the micro switch whilst the switch is still attached to the pcb, is that also the wrong method please, I'm just a novice trying to repair this BP monitor for a patient please can someone Help Me thankyou. Great video thankyou.

01:55 Here in the USA 230vac between 2 wires is a 230/240volt circuit, therefore BOTH wires will/should be HOT (120vac each). (Blk&Yell = 230vac circuit here). Blue could be Neutral or Ground. Always Test it, if you are in doubt. I use several methods and dbl-chk, "IF" I am in doubt of the type of circuit I am working on. Thanks for the video-- the more good info out there the better.

Can any woofer speaker be tested like this? I'd try starting test with lower voltage 3V, 5V, ...

What is the difference with YIHUA 948 I ? Which one should I buy?

Nice

2 year old and already using AI, damn.

Only half tested. If your going to take the time to do a video do it right

useless video, doesn't distinguish between the dials for dc and ac

Joke?

Your sound boring

And yes we got 9 volts . . . . . . because the battery is STILL connected! 😎

You lost me by not playing a tune.

Yaaay! So cool😂 I think, with DAC built-in microcontroller, can make more precise pitch.

Thank you for this I'm fixing my amp and I need to change smd and mosfet

For this to sound like a major scale you would need different resistors for the connection between the 3rd and 4th buttons and the 7th and 8th buttons.

Very good video keep it up

That applause sound was very loud. I really liked that you explain everything in detail.

Спасибо!

Strange outlet

What about the Milka brown resistors how to read this?

I thought OL means open line???

You never mentioned what symbol on the multi to set the dial to, nor what sockets the red and black wires were hooked into.

Learned more in 1 minute than 1 lifetime in school

Thank you for the video!

Use two 555 timers and you can have effectively 6 leds that look like they flash independent of each other, connect two leds to the outputs, one to + rail the other to - rail, do same with 2nd timer, then connect two leds parallel but reverse one and connect to outputs on both timers to them, timings are a choice, but I normally go for between 0.5 and .75 seconds on one and 1 second on the other, i built one for a 5 point star with 5 leds on the points and one at the center.

Absolutely silly video. That's only checking voltage and functionality. Stupid....

4:15 are you sure about that? 6 x 3300 resistors in parallel is equal to exactly 550 ohms, so the resistor is perfectly fine. You didn't mention the way series and parallel resistors work here lol.

Of no use

Thank u

Is it good to use Themisto or Uni T multimeters with capacitance function upto 100 millifarad to test capacitors?

Very Nice!

4 band resistor reads value, value, multiplier, tolerance. 5 band is Val, Val,Val, multiplier, tol. EG: 4 band = Br, Bl, Red, Gold = 1000ohms with +/- 5% tol= +1050 & - 950ohms. 5 band is the same except one extra value. EG: Br, Bl, Bl, Br Gold. = 1000ohms +/- 5% tol.

Screwdriver method cheaper and easier

Why not shove the probes in the socket?

Me gain knowledge,me happy,me supasakaraip

The voiceover is excruciating! 🤦🏼‍♂️

Arduino do it better 🗿

I have all the parts except the speaker in both through hole and surface mount. Maybe if it works well I could order a few PCBs from China.

If you ask me to like a video before the video even begins, I will automatically dislike it. This video made me feel very satisfied with that policy the longer it went.. I'm halfway through and it stop hasn't gotten to the point..

And were is the speaker in the schematics?

Thank you for the quick and easy without bombing me down technically.

Newish to electronics as a hobby been playing around with 555 have not came across how you have wired the circuit so will be trying it out, thank you for clear understanding of the circuit explained extremely well. Happy New Year
