[@markys441]

Also, an important component is Relay. I also highly recommend having some more powerful NPN and PNP transistors just for amplifiers, since they are quite popular too. For NPN I would go with BD139 and BD911 and for PNP BD140 and BD912. I would also recommend 4R and 6R power resistors as a load. Thanks for your amazing content :)

[@sebo0855]

Also don't forget the 2sc5200 and complementary 2sa1943 for more beefy amps, and 2n3055 with MJ2955 to build extra reliable power supplies and vintage power amps ( those are REALLY tough ones ), and the most important thing of all with this kind of semiconductors, NEVER buy BJTs from unknown supplier, all of these transistors are very likely to be counterfeits, most of electronics projects with these fail due to crappy fakes. All fakes that i found very common: BD139 BD140 BC550 ( noisy ) BC560 ( noisy ) BD911 BD912 2N3055 ( often die size 1.5mm² instead of proper 5mm² or no die inside ) MJ2955 2SC5200 2SA1943 2N2222 ( no die inside or low max freq ) BC557 ( no die inside package ) 2N3553 ( not working in RF ) common IRFs but on higher voltage/current. Power LEDs NE5532 NE5534 AD827 ( and similar ) MUSES opamps And many more out there Always make sure you got quality parts that have proper SOA.

[@OrbitalCookie]

Few things I learned since I started with electronics: - Start a project, however simple, and then buy components. Few projects in you will get wide variety of stuff. Few more projects in you will have too much stuff and never exactly everything necessary for that next project. - Label and catalogue everything. This is hobestly the most annoying thing about electronics. - SMD components are super compact when compared to TH. Yes, you may need TH to prototype on a breadboard, but a SMD kit can be much more comprehensive and compact. - If you order PCB, go with SMD! Honestly SMD stuff is so much easier so solder and your project can be much smaller. - Just keep SMD sizes sane. 0603 minimum for resistors/capacitors, use only those ICs that have visible pins to touch with iron. - Have a cheap iron with adjustable temperature and a tip that can be replaced with a small one (by some chance I have the ERSA one that is on Great Scott's workbench).

[@Kalvinjj]

Great tips, i would only change one thing and it's on using SMDs if ordering PCBs. I would always go with trough-hole components when ordering PCBs, and SMDs if doing the PCBs myself (tho I can understand that it's not as easy to make the traces for some smaller SMD ICs), since I would not need to drill the holes myself on the purchased PCB and through-hole parts are still easier than SMDs to solder from my experience, and specially with cheaper soldering irons. Now, if I'm making the PCB myself, I'll want to drill as little as possible so I'll always go as much SMD as possible, just avoiding SMD connectors like the plague for durability sake.

[@TotalWarChronicles]

can someone please explain what bootstrap means for electronics at 7:48? I have been trying to figure it out watching videos and all, but i cannot make sense of it

[@hodissergiu8883]

Bootstrap is needed for high side switching. If you consider for example an Buck converter, the Mosfet is between the voltage source and the inductor. You want the Vgs higher than Vth, usually arround 10V to make sure the mosfet is fully saturated. if you have an input voltage of 12V, when you turn it on there will be 0V at the mosfet Source, so you will have a Vgs voltage of 12V. But as the mosfet starts conducting, the source will be at 12V as well so the Vgs will be 0V. You need a bootstrap configuration to raise the Gate voltage above the Source voltage so that the mosfet will be on as a high side switch. Sorry for the long post.

@@visualeffectschannel Because if you don't. the mosfet lets out the magic smoke. Think of it this way: A fire hose has a valve, a tiny itty bitty control valve. When you turn on the water, if you put fire hose pressure on the itty bitty control valve, with nothing in the fire hose input, the control valve will shoot into the hose, and you will break the thing. My best metaphor.

[@Samuel-km5yf]

TotalWarChronicles - Ignore the other responses, especially the one about the firehose because it’s total nonsense. Bootstrapping in this case is referring to using a higher voltage to bias a device above it’s supply voltage. Let me explain... N-channel MOSFETS are often preferred for switching because they are generally faster and have lower on resistance, Rds(on), compared to P-ch MOSFETS. If you need a high-side switch, P-ch is simple to use because they are turned on by pulling the gate below the source, i.e. apply -Vgs. However, if you want the performance advantage of an N-ch, you will need to figure out how to generate a gate voltage higher than the source, i.e. apply +Vgs - something that is usually easy when the source is tied to ground (aka low-side switching) but difficult if your source is at or near the supply voltage (aka high-side switching). This brings in *bootstrapping* - that is, using a bias voltage (gate voltage) higher than the supply. The IR2110 won’t generate this high voltage for you but you can get it a few ways, e.g. maybe it exists elsewhere on the board or system or perhaps use a charge pump circuit. Anyway, Great Scott is saying the IR2110 is nice because it conveniently allows the use of bootstrapping thanks to the high-side driver output being isolated from the rest of the voltages inside the chip.

Esential component needed before doing any electronics project is initial knowledge from Great Scott's videos.

[@TotalWarChronicles]

IS someone also able to explain to me what a mosfet driver does and why it is so necesary?

[@greatscottlab]

I will do a video about it sooner or later.

[@ethanmye-rs]

The mosfet has some gate capacitance. If you want to switch your mosfet quickly, you need to charge the gate capacitor quickly. A gate driver lets you do this, and might throw in some other niceities.

When switching from a low logic signal to a high logic signal, transistors behave like resistors, and they can heat up quite a bit. The faster you can switch the transistors, the less heat is produced. If there is too much of a heat build up, you'll fry the transistor, since they are not meant to operate at high heats

Before the internet and search engines I would go to my local library and find a book on the subject in the American series "The Idiot's Guide To." eg "The Idiots Guide To Calculus." These days libraries are an endangered species.

[@TheRainHarvester]

Here is an explanation/example: kzbin.info/www/bejne/e3fdZGyah7VspaM

[@spinxsunyi]

This video is so satisfying. It reminds me of my school days in electronics engineering.

[@EasyElectronics2412]

Because of lockdown i don't have a single resistor laying around me😂😂😂😂😂😂😂

[@AnandKumar-ym9yw]

oh social distancing 🤪

[@ashfaqjuna]

Resistance is futile

[@ethansprojects7399]

I get all my components from old electronics I find by the road lol

[@sataniclemonade9132]

I just watched EVERY video of yours in 1.75 speed 😂 amazing content, subbed

[@electricityman1162]

Hey GreatScott!, I live in Germany and could buy the parts at Reichelt. Now my question is, if I should purchase the parts there, or just buy them much cheaper at Aliexpress. Is there a big difference of quality between those parts? Or is the quality almost the same?

[@plageran]

If you can support local go for it, import duties are shit expensive in RSA I'd rather get it from my local stores to support them.

[@sgsax]

Resistors and capacitors I understand. Inductors I still have no idea what they do. Great overview for basic component supplies. I need to expand my collection now. Thanks for sharing!

[@lpt2606]

2:17 nope, have you never dropped that box? and then clean everything up again. nevertheless they are handy

The best video on KZbin

[@meenakchipalaniappan4128]

You missed about "shift registers"!!!

[@carlos2004]

don't forget the h bridge ic's for small motors. pretty handy for mechanical projects.

For Arduino MCP23017 works better

The wall mount storage drawers shown are on sale at Aldi in the US 1-2 times per year for under $6 each. There are 2 versions, the version shown in the video with the yellow dividers, and another with the same case size, but fewer/larger drawers.

[@rickseiden1]

I think it's a little unfair to say that JLC has fast shipping times without talking about how they do it. If you want fast shipping time, you have to go with DHL, and can expect a lot. I just ordered 6 different PCBs that came to $21. The shipping on DHL was over $17. If you go with their standard shipping, which costs much less, you can expect to wait at least 2-3 weeks before you see your PCBs. I do use them quite often, and I do try to go with DHL most of the time, but I can't always justify the cost. If the PCB cost $2 or $4, and shipping costs me $12, it's just too much. So, yes, you can get fast shipping from JLC, but you need to expect to pay for the privilage.

[@virtualtools_3021]

I wouldn't complain so much about it, sure beats making my own PCBs using toner, copper foil, plywood veener, and dangerous chemicals...

[@kavehchannel]

You are amazing ! Your videos are AWESOME! Keep up the hard and GREAT work.

[@SurajGrewal]

Be jealous...I live half a kilometre away from a repair competent shop I don't need to stock up on anything except for microcontrollers

[@shubhamchavan22]

Very nice basic components video helps lots during lockdown

[@greatscottlab]

Glad it helped :-)

[@harshitaharshita6543]

You started your channel on oct 2(the birth date of Mahatma Gandhi)

[@suitcasegaming]

Don’t care

[@masbejo3625]

I watch your videos from freshman year until I graduated college. Your videos also kinda helped me finish my final project. Thanks man. ONE IMPORTANT QUESTION, Is "GreatScott" refers to Dr. Emmet Brown swearings ? That's all. I WILL SEE YOU NEXT TIME !

[@kashyapkoshti]

You missed most important thing "power supply" @greatscoot

[@donaldfilbert4832]

Outstanding! Completely informative - yet succinct review of components ! Best I have ever seen !! Thanks a ton GreatScott !!

[@greatscottlab]

Thank you very much😁

[@gunox7]

While talking about fuses, don't forget to add Varistors and required filters for efficient and reliable power units. For externally powered projects, common 5-9-12V connectors will be good to have.

[@Z-Ack]

I usually desolder all my essential components from old stuff.. and keep the boards all in totes so if i come hard up for something specific i can sit down and look through all the pcb’s.. i label the totes according to use and voltage.. like all audio stuff, 12v stuff, appliance stuff, video, etc..

[@WarrenGarabrandt]

I consider a smart phone an essential component when building a circuit so I can pause as necessary and follow along with your videos.

[@dozog]

🤣 I use my smartphone to keep my PCB down on my bench when soldering. Yeah, it's a vital tool.

[@just4electronics101]

Every Sunday I wait for your videos 😍

[@greatscottlab]

Yay! Thank you! :-)

[@mihaichirila9127]

Same

[@baserockbathead]

Would love to see you do a video just like this on your most commonly used tools too!

[@phlynniii]

One of the best basic electronic videos. Thank you so much for your work

[@vivekvishwakarma9223]

Nice describing man. Easy to understand ur information. Thanks dude.

[@waltercomunello121]

Wires are the great unsung heroes of electronics. I consider "wires" different from "jumper wires". Small coupling transformers also used for em filtering.
