Thank you!

He got the RC filters backwards on the comparator inputs.

Did you test it? I found some errors.....

GreatScott is best solder men.😂😂😂😂

Don't want to sound like an asshole but GreatScott isn't all that great at electronics.

You really understand about the topic. I need an not expensive 500A ESC for a bike project. Do you think changing the mosfets and capacitors in a commercial esc I can achieve this ?

Thank you so much

So gald to hear that!

Funny. Those of us that are tech savvy are usually introverts that don't get out much, and are less likely to be seen in public. ....like right now... this is my procrastination break with a half finished KiCAD board layout on a laptop in front of me. Commenting on and replying to people from the vids I watched earlier with my morning coffee is my version of "getting out / entertainment." Just don't hang out with the sheeple that lick the cones and dispute the bath waters :-) The internet is a wonderful place to connect people that have no immediate contacts to other "tech savvy" people IRL. I live in one of the most populous places in the world, Los Angeles California. There's SpaceX, Boeing, NASA, and world class universities within 100 kilometers of me, and yet I live in a dead zone with no one (I know) around me that has any depth. They all just stare at idiot boxes all day. So I find people on the internet in places like YT, and try to get them to engage. If you're having trouble finding stuff, click my name, go to the "Channels" tab and start exploring. Most people, like myself that really engage in comments sections (aka 'talk too much') are looking to build community, are very active on YT, and leave our account completely public. My subscriptions, likes list, and playlist references to other people's stuff are all public. I have nothing to gain in sharing this. I'm subscribed to well over 1k channels, have a maximum sized "likes" list with 5k uploads on it, and have a large number of playlists on everything electronics based that I'm interested in. If you can make it through those lists without being overwhelmed, you're a much smarter person than me. There are thousands of people here just like you. Most of us probably feel similarly about the state of our immediate surroundings IRL, and yet often we neglect to realize or appreciate we are all here together right now :-) -Jake

@@UpcycleElectronics , you sound interesting. Just added you. Check out my channel as well.

@@UpcycleElectronics I can confirm that, most of the smart people are introverts. I for example, wouldn't want to come off as a narcistic, but i'm a relatively smart dude that does dumb shit once in a while. I have tested my IQ, it is ~175 apparently, i was a member of Mensa until they became too greedy and started asking 120€ per month to continue being a member. I started learning electronics when i was a kid, since i grew up way too poor to own fancy toys and such, so my grandfather ( former professor on the college of applied science) would give me a multimeter, set it on the continuity and i'd go chasing things around to check if they are conductive. That was when i was ~5 years old. After i grew up a bit, i had started to repair toys that we got second hand. Well, i mostly took them apart and attached a loose wire with bubble gum lol. Now, i'm about to finish my college and to get master's degree in mechatronics engineering. I'm a goddamn introvert, i don't have a girlfriend and only have a few friends. I think this is same for most highly intelligent people on the world. Also, your channel is pure awesomness. I'm working on a Arduino Nano based bluetooth multimeter project, that should be small enough to fit in your hand and you should able to get readings on your phone. Mostly doing it as a cheap alternative for Mooshimeter, which is awesome for students but is quite pricy.

What's the accomplishment there? There is VESC, high-end open source ESC. There is Blheli_s, consumer ESCs with open-source firmware. This project is toy-grade.

@@dmitryplatonov BLheli does not compare to this. This dude made a whole thing himself, and i imagine quite cheaply too once you rule out R&D costs. On the other hand, BLheli is still expensive compared to this, and you have to buy it from them, unlike this which you can solder at home. The blheli_s is around 17 dollars a piece, or around 60 bucks for a set of 4. For this, you can get pcbs from JLC for under 5 dollars for all four. The components are SMD, hence dirt cheap. I'd say just a few bucks to make a single ESC.

The board has both UART and ISP pins for programming

Thanks!

Glad to hear this! Feel free to share your projects on electronoobs.io keep up!

Are you considering selling the board and the components as a kit? I'm not being cheeky or lazy, but with kids and full time job I'm a bit short of spare time... :-D Regards

Yeah i also want a video on this.

Happy to hear that. Good luck!

@@ELECTRONOOBS Thank you!!! and hope your kick starter is successful!

The idea is to make them preassembled with a pick and place. But I never done that so if I can't do that, well maybe a kit. Not sure yet....

@@ELECTRONOOBS pick and place ideally needs all smd components on one side of the pcb. (It can be done on both, but gets way more complicated.)

@@TheRainHarvester thank you for that. I'll have to ask this to the PCB manufacturer and see what they will say...

@@ELECTRONOOBS Sure thing! In my research, having a board populated is expensive: $5 for 3x5pxb and possible increase cost in components and/or shipping to send them components. Have you found good prices?

I was just gonna say that... I have plans to use that single analog comparator as a current sensor... Just have to touch up on my coding

I'll look over that. Thanks!

I have a "snap brick" robot controller I'll be releasing a video on soon (plz subscribe). What website specifically are you recommending for crowd funding? (I think kickstarter charges too much).

Sorry, i've done that after I've recorded the video... I'll be more careful next time

Acetone might remove the solder mask

Yes please! ♥️🥰

yeah 5kw so we can put these in our cars.

Hi. What do you mean? The sensing dividers are of 10K with 33K and that will lower the voltage to around 2.7V.

@@ELECTRONOOBS Yes but the VNP is approximately the supply voltage divided by two. I have seen bad schematics online which divide the three phases but not the VNP. Here is a link to an ideal setup: imgur.com/a/CskN30V. I think your ESC works because you take the neutral point after division, after looking at your schematic. You wouldn't need to denounce your comparator in the code so much if you took the VNP separately. This would allow for higher speeds!

but GREAT job overall and this is just my preference based on my projects use case but is not necessary and maybe not even best just for learning case like this board may be for. I am meaning more for use in actual projects
