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.

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).

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.

@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.

@Samuel-km5yf

4 жыл бұрын

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.

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

The "electrons" around you are happy. Your Video is the easiest to understand than any explanation in Japanese. Thanks. I started collecting the "Essential Electronics Components" you showed. I like the "Electronic Basics" series.

A very useful video of things to buy for an electronics kit of parts. I'd like to see more videos delving into more components and things that are needed and even not so often needed. Then you could always do one for tools too.

Hey, you should make a video about storing these components most efficient and cheap way.

The way Scott did it is fairly efficient already. If you want to go the cheap way, just sort the parts into small bags and put them into storage containers.

He is already talking about it around 2:00, there is also cheaper ones without wall mounting option and more smaller depending on your needs

@@atahandoruk Yeah, I've always considered proper storage boxes, but I don't really have much space where I live. I actually keep components stored under my bed, or on my bookshelf.

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?

@@gormenfreeman499 I think none of such simple components are made in Germany any more. Everything is imported from Asia anyways. Reichelt, for example, is just a distributor. Nothing wrong with supporting them, of course.

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.

I have been doing this for over 45 years and this is the best list, ever!!

Thank you😁

Thanks for the video, this was exactly what I was looking for!

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.

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

You missed about "shift registers"!!!

Great video! I loved your storage!!

I've watched many of your videos, it always attracts my attention that how you speak in a rythmic way. 😊

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

You missed most important thing "power supply" @greatscoot

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

Great video as always, looking forward for a similar one in the tools section. 🙂 Also, a ton of thanks for putting all the Aliexpress links into the descriptions! 🙏

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

You will be always remain great!

What a super useful video :D Thanks!!

Thank you! So awesome to see this info. Keep it up.

Thanks for all the videos. I learned a lot from you. Greetings from the Ruhrgebiet

This was great! Thank you! It would be cool to see this done from an audio point of view.

This was exactly the video I needed!!!

Keep it up Sir! Thanks for making awesome videos! From 🇵🇭

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

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

Great video! All of those discreet components only need one thing, hook up wire and clip leads. They are not really tools but part of the test circuit.

Scott!, you are just Great!
