Thank You

Awesome !!....cheers.

That's how I make white noise.

Bipolar? Sounds similar to the topic of my most recent video about AOC! LOL Just kidding. Excellent presentation as always!

I have a 260w panel that's about 30v. Will it be suitable?

I have a need for resistive voltage dividers in my projects. I am trying to model the 5v output of your circuit with a 5v (high-current) breadboard source. It seems I need to put a resistor(s) in series to simulate the divider. So far, I am about to determine if a single series resister with the 5v supply will work. I plan to try certain loads, looking for, I hope, a single resistor that matches the divider's pulled down output v.

Interesting. I've never thought of testing transistors backwards. Thank you.

This confirms my suspicion of a fault that I am seeing on a circuit prototype that I am debugging. Thank you.

I've run across many wired wrong like this...

I took Ra=I4K, Rb=100K and C=0.22u and calculated th=0693(Ra+Rb)C=17.38ms and tL=0.693(Rb)C=15.25ms, neither the period T=th+tL=32.62ms nor the tw coincide with 20ms and 2ms, respectively.

How can it be that the motor moves? Regards

Excellent. But it's more fun with two potentiometers, a second potentiometer on the + input, which allows you to see if the AOP compares correctly on different voltages.

can this be applied in motors?

I think I fried mine, when using a 12v instead of 9v adapter. got a little smoke and now the whole thing gives out 10v instead 5v 3.3v still works tho

Solder wick is your best friend when soldering. You can clean and save that breadboard with it. Its a must have.

Your videos are so much fun to watch. I love how you teach.😊 I just ordered these two MOSFETS from Mouser Electronics. I got 10 each.😊

Interesting video!

Ive had one of those irons, it burnt through tips to no end. I still use a 30W that connects directly to mains, purchased in 2011. You need more liquid flux and better solder wire. Pace and Northridge Fix UA-cam channel have great videos .

danke

A bit of a tangent, but I use a timer on my soldering iron so that it automatically turns off after an hour. It’s easy to get distracted, so I like knowing that I have a “fail safe” system. I’m going to try the ideas in this video (and in the comments) because my soldering iron gunks up frequently.

Does this relay need a fly back diode when trying to power a 12V solenoid valve?

Does this relay have a built-in diode?

I like your videos and you know a lot more than about electronics than I do. But... I can solder-(very, very well and even SMD ) - I started building electronics kits back in the 60s. Tip tinning is about keeping the tip in good condition. The tip tinning mix is to recondition the tip. Tips usually get a bit cruddy (corroded and pitted) from all the the different fluxes etc. Clean old solder etc off (brass wool etc ), Dip the tip (into the treatment) and then it is good to go for several hours of soldering. No need to keep repeating.

I'd recommend being much more aggressive when using the brass wool. Really stab the tip in there and rub all sides hard against the brass to really remove the oxidation.

I never did use this flux and like using the wire cutter i used to sharpen the place where I would need the soldering iron to be working

woo hoo soldering!! 😃don't breathe that stuff!!

Hola, muchas gracias por tu explicacion (muy util por cierto). Cordial saludo desde Argentina

Thanks a lot my friend

Fun fact: you can create a random signal generator by wiring 2 of those LEDs in series and taking the signal from the connection between them. Because of imperfections in real life materials, the LEDs flashes have slightly different timings and current draw, and as one of them draws current, it changes how the other behaves, and vice versa.

How much voltage (V) are you using to power this circuit? We can observe something is inputted in the DC terminal but it's unknown what is on the opposite end.

...looks like a good switch debounce circuit....maybe a smaller cap for this app though. THANKS AGAIN!!!

Thanks for a great clarification on a series/parallel configuration.

A very musical circuit!

correction.......high-low-high. THANKS AGAIN!! --dalE

I needed a clean single pulse to trigger a controlled pulse in a monostable mode 555 without using another 555 trigger. I searched YT for "single pulse generator", and in ALL the 100's of videos that came up, I could find nothing simple. Then I found your two videos that were JUST THE THING I needed. THANKS MUCH!!!!!!! I plan on using the low-high-low version. --dalE

GREAT VIDEO!!!........one thing though... At 1:39 the 100k resistors are in parallel. so it's actually 50k discharge...not a 200k discharge.

To power a 5v led with a 9 volt battery what resistor should I use?

I’m guessing there’s no way that this IC creates a delay like the other hex inverter ICs you’ve looked at, or am I missing something? Finding it hard to imagine a case where this would be useful but i’m pretty stupid so there’s that😂

Thank you! I was looking all over the web for how to do this until I found your video, and now I can move on. I was looking to see how a capacitor stops the flow of current once it is filled.

Wonderful instruction. Subscribed! Your notes that you use, are they your own prints or from a book?

Can i use a 16 gauge wire terminal on a 22 gauge wire?

Thanks for your wonderful videos. I have a quick question. Can a PIR be placed into this circuit that would trigger the servo?

How much voltage are you providing to the cathode of the photodiode while keeping the 10kohm resistor in series?

I lost my saved data, and had to revert back to 4 levels down again and was looking for gameplay on how to go through this mission with ease because the first time I kept dying and had 3 legendary ghouls on top of the glowing one to kill, and I was level 11 when I got through it when my deleted saved data was nowhere to be found I loathed having to repeat this again but thanks to your vid, it’s given me the courage to give it another go, so thank you 😃💫
