Decoupling capacitor near the power source or near an IC chip acts like a shock absorber in your car. While the IC circuit is in operation its current consumption fluctuates up and down, at times the current fluctuation maybe sudden and dramatic if driving high load current. The capacitor near the IC acts as a Low Pass Filter (or shock absorber) to prevent those heavy sudden fluctuations and to ensure that the IC operation is maintained steadily - due to severe current fluctuations the IC may suffer failure. By the same analogy if you are driving your car on the highway and suddenly encountered a bumper or little stones then you may not feel it and you keep feeling comfortable, because your car's shock absorber springs took the shock and you didn't feel it - and you are still in that happy safe feeling. Thanks to the capacitor springs...!
❤️❤️❤️❤️❤️.....crucial info you just shared with us!!!!! This is very commonly deployed in High-End SMPS like Corsair brands directly on the socket itself ,beit for PC or other electronic devices...the only setback is the poor quality of the electrolytic capacitor they use for such high priced SMPS.

As a student I can do all of the circuit analysis and math to find gain or frequency cutoff of a given circuit, but this taught me some of the thought process behind the choices made. Thanks.
Ten years ago I used to teach students and coworkers electronics and programming and I still do it today. I find your TH-cam videos pretty neat, job well done, keep the great work.
Great video, thank you! I learned some new things about capacitors and transistors. Two corrections: #7 "LEDs... are quite slow to react to a high-frequency PWM signal." Nope, LEDs turn on and off very fast! Most people can perceive an LED blinking at 200 Hz; some can see >300 Hz. Always use PWM frequency >400 Hz for dimming LEDs, or you may notice the blinking. #8 "Provide individual traces when connecting different signal references back to the ground or common node." In the apps I've used, doing this in the schematic doesn't constrain the PCB layout at all; you have to remember to do it in the PCB editor.
You are correct. The video says that they are slow to react, but in actuality, it is the human perception which can be a bit slow to react, relative to circuit (digital signal/PWM) frequency. LEDs themselves can be quick enough that an LED and high speed photoreceptor could be paired and used for sending an audio signal wirelessly.
In case of the ground return, copper pour or additional layer for ground is always helpful, if your circuit does not have any contraindication or constraint for that.
Ben eater has a youtube series where he built an 8 bit computer on a breadboard using just logic chips, I think that's as close as one can get! It is a very informative video series.
Tip#11 Reinventing the wheel. There's plenty of circuits already made for most applications. Just pick one and tailor it to your application. There's rarely a need to start from scratch.
Yes indeed, but also do not get afraid to invent if that is not available. Be aware and wise enough to judge that, the available circuit is modifiable enough to fit into your need.
Thanks for remind me about the darlington pair transistors, I have been having problems saturating single bipolar transistor with little current because of low gain...
Bro super explanation of Videos this is first time i watch your Videos Nice time useful in Spending in Lock down .It created a Superub Experience awesome still more and more Videos are expected from you thanks a lot.
The reason of tip number 8 is that potential may differ a little ? This is only useful in extremely precise applications ? Or is it needed on a larger scale ?
Very helpful. I'm not a professional designer but I like to hack things together to either make something fit my purpose, or from scratch if none exists. I'll keep these points in mind as I advance to more complex circuits. Particularly what you said about using a micro-controller rather than an assortment of discrete parts - something I should work on. That being said, a 555 timer, a cap and a resistor versus 2 caps 2 resistors and 2 transistors, they can each accomplish similar goals but the former costs about $0.67, the latter, about $0.30. That's been my justification for my fear of IC's. But if I want to build better things with greater capabilities and accuracy, I really need to work on that "fear".
What you said is absolutely right but sometimes using discrete parts can get really messy. When developing products last thing we want it to be messy. Also I didn't shoot down the possibility of using discrete chips but rather spend some time to find the right way to achieve the objective the efficient way.
@@Gadgetronicx that is correct. And material costs is often not an issue for a maker. If you have a simpler solution you safe time and effort, event if it costs a few cents more. And the well known multivibrator solution with the 2 transistors, 2 capacitors and 4 resistors has serious drawbacks. One is the signal steepness, another one is the limitation of operating voltage to a maximum of about 5 volts (otherwise you get avalanche breakdown of the base-emitter diode of the transistors, which can be harmful if the capacitors have higher capacities, because the stored energy ist "burned" in the pn transition).
This is the right time to watch such a great video that collected almost 60% of the tips that I need for my graduation project. I thank you, sir, very much.
That's a good question. Technically both the capacitors are decoupling ones. But the key difference is that the big bulky one serve as a charge bank and supplies the chip with current when there is a brief interruption in power supply. However small capacitor will be fast therefore it will be much effective is responding to voltage spike from the supply
what happens if I use 1V 1AmH battery for a circuit that consumes 1V 2AmpereperHour? Does it just break the battery or it just gets discharged quickly?
Hi Sai, Ampere per hour is meant to refer the battery capacity. It's the most common method to specify a battery's capacity. Whereas when you refer to a circuit drawing 2 Ampere it means that it is consuming 2 amperes per second. Regarding your question theoretically if you draw 2Amps from a 1Ah battery it will discharge in half an hour. But batteries are quite complex in practical circuits. Discharging a battery's full capacity can certainly cease it from working. It also depends on its battery chemistry
Sir I have a doubt ,when capacitor is connected in parallel to the ice or supply voltage ,it becomes a junction .in these cases the capacitor will have same voltage and ic too have same voltage can plz clarify these
I have a rechargeable electric shaver with a 2W resistor in the recharging circuit. This electric razor cost $70 when new. While charging, this resistor slowly burns itself up, especially if you deeply discharge the battery, the battery goes bad, or when you use it while plugged in. Once this resistor dies, the whole shaver quits working. From an engineering perspective, this resistor was selected as the most cost effective choice. But in practical terms, this is an engineering failure. I replaced the resistor with a 5W variant and the shaver has lasted me over 20 years so far, even after the rechargeable battery quit taking a charge.
hey new idea old subject that is if you have knowledge of computer programming and how to build them. led panels controlled by bios chips with voltage sensors placed at the end of every led to control and prevent over voltages of the led solar panel system. a bios can be augmented to allow the pass through of electricity only when needed just like the operation of a microprocessor. in this way only a portion or even a large portion can be used to create effective solar energy. this is possible because the bios program will only allow energy in when it is needed. this will prevent over voltaging of household circuits. a simple switch sensor will prevent too much power from reaching the circuit by saying it is not ready to use. this can be tested with very bright flashlights to prove how many chips will be needed in a circuit and should be test by someone. good luck.
Ouch, yes agreed. When I started, text books didn't convey a lot of practical aspects of design. You had to learn from others. Much like high school doesn't prepare you for life. Teaching by rote is at times cruel, especially when the subject matter is wrong to start with.

A good instructive video but the annoying repetitive background music made it difficult to maintain concentration.
nice video sir!! , I'd like to ask why should we use two capacitor electrolytes and ceramic as decoupling?? is it enough to just use 1 capacitor??
That's a good question. Technically both the capacitors are decoupling ones. But the key difference is that the big bulky one serve as a charge bank and supplies the chip with current when there is a brief interruption in power supply. However small capacitor will be fast therefore it will be much effective is responding to voltage spike from the supply
Can you explain tip number eight “individual traces” and why connecting them together will cause humming noise? Thanks.
Careful with external pullups, bias circuits, and inductive spikes when using an mcu. A few volts over the gpio rated max can brick your processor.
