this video clearly/directly showed how much patience,hassle,experience is required for making my own stuff

This is exactly the content I've been looking for. Explanation that is deep enough and doesn't waste time or beat you over the head just to make a video longer. Keep it up man! I love it.

3:03 _you are the only person I know who uses a _*_ruler to highlight_*

He bost He charg But also protec

I don't know ....why....I just love your videos...I am addicted..you are really great in electronics and all. I am watching your channel since last 7 to 8 month but you always inspire me...thanks for such a nice and good content. Love from India...😀😀😁😁

I'd seriously buy this as a kit. Great job!

Great Scott, thank you! Extremely clear instructions on selection, design, sourcing, testing. You’re making my bigger projects possible. Plus, power supply has always been my biggest question, not anymore, I’ll follow your path on this. Thanks Again, Davidian.

this is a really well done video, I can tell you put a lot of effort into the timing and pacing of the video. It shows all of the detail while keeping the video short enough to be interesting and it is really perfect, so excellent job as always!

You are the f***ing best UKpostsr I know!!! Please keep up the vids, they are awesome. They help me with some many thing.I always have questions about these things and I always just find the answers on your channel.

Warts and all, thank you for sharing. Always worth the time to watch anything you post👍🇬🇧

You make awesome videos GreatScott! I'm learning a lot watching all of your videos. I understand electronics to a limited degree with a solid foundation in passive components but designing with ICs trip me up. The information provided in your videos along with the resources of EasyEDA designing software, LCSC parts store, and JLC PCB will greatly help in my future projects. I hope you keep making high quality, informative, in depth, interesting project videos, even if a few of your more advanced videos are difficult to grasp, I not only steadily understand more of your content but electronics design more with every video.

Wow ... your work is (as mostly i saw) very accurate and you did double (and tripple) check everything. Great job! It's satisfying to watch you work

A week ago I did my first smd soldering! It went very good thanks to your tips! Thank you very much!

Interesting and useful facts: 1) If you only purchase 5 boards (instead of 10), the shipping cost is lower. 2) If you use "Panel by EasyEDA", you can fit more boards in one panel (2x5 panel in this case) This results in 100 boards (2x5x10) at the price of 2$ !!!

Dude, you are the best. I am studying electrical and computer engineering, and i love watching your vids, you make everything seem so easy.

Thank you so much for making videos like these! It's because of people like you and bigclivedotcom who make such amazing videos that I'm working to become an electrical engineer!

That custom board service sounds amazing! Coupled with that diagram app and it looks like you could prototype anything super quick

all week waiting for u scotte ❤❤❤ keep up man

this video clearly/directly showed how much patience,hassle,experience is required for making my own stuff great jooooob broo and please we need more videos from the technology, u are genius and god bless u,

I'm not really an expert in pcb design, but I always use planes in the power sections to avoid drop power problems. Thanks for the video, everything is really well explained.

I'd love if you explained more why the first variation of your pcb didn't work properly in the video. The requirement for shorter and wider traces was probably mentioned in datasheets, so we have to give it more attention in our projects :)

Excellent job, as always. You could use a Dummy Load, maybe a next project? regards

I like the way you do presentation, printing out datasheet and pointing out important detail using highlighter pen on the datasheet. Keep making good video

I am not worthy. You are truly an engineer. I love your presentation style and seamless editing. I learn so much from just 1 of your videos. Keep broadcasting.

As someone who knows how painful it can be to design, layout, and manufacture PCBs, you made it look really easy! Their software looks very much like Altium only web-based, and a few thousand dollars less too! A few tips for soldering SMT components: Make sure your Gerber files do not have a solder paste layer if you intend to hand-solder the components rather than a pick and place machine. This will mean your boards are (mostly) flat and free of excess solder which makes it much easier. If there is extra solder from the solder paste or HASL finish, then use solder braid/wick to remove it. Soldering SMT capacitors and resistors, apply solder to the PCB on one of the pads of the component and keep the iron on that pad. Using steel needle nose tweezers, slide the component onto the solder pad. Remove the iron and let the solder joint cool. To make sure it is flat to the PCB, rest the tweezers on the top side of the component with very light force and briefly touch the iron to the pad. Then simply solder the other pad. ICs are pretty much the same. Apply solder to one pin on the PCB, slide the IC into place with tweezers making sure the other pins line up correctly, remove the iron and let the joint cool. Make sure it is flat against the PCB, then solder the other pins starting with the pin most opposite. I find this method more reliable and produces less thermal stress than heat reflow with a hot air gun. If you are going to heat reflow after soldering for presentation, try using flux jelly in a syringe from the usual suppliers. It helps for faster reflow and a nice shiny finish. Makes soldering a lot easier for me! Hope this helps! Keep up the great work with the entertaining and informative vids :)

Boost 3.7v to 5v so that the board being powered can regulate it down to 3.3v

LOVE THESE KIND OF VIDEOS!! u blond german nerd who knows how to shrink a like 3-4 weeks project in 11 minutes and gives the importance of showing its own fails as part of the process of learning. Thank you for making such a good quality videos!

I had struggle in charging and battery management Circuitry.. Awesome Work.. so much patience.. Great Scott-Great Work as always.. Thanks for your time and efforts.. Love from INDIA.

Hey! I ordered your PCB and the components. Looking forward to putting the parts together. One thing you should have mentioned: the shipping cost. Its not terrible but 2$ for the PCB and 7$ for shipping is something that should be mentioned. Cheers

I love how 1 day difference in build time cost 29$.

Man you really are amazing, sometimes I'm just in awe... thanks for everything you do and the way you explain it, that's how I'm able to learn!

Got notification about new video, came, LIKED, started watching it.. This much I love GreatScott. :)

Can you please describe what was the problem with your problematic layout. Really curious. I see no big differences in your first and second layout so will be appreciated for detailed descriptions.

6:07 it says IDONTKNOW in file explorer.

This is awesome! Just what I've been looking for to continue a project I've had on hold. Thank you so much!

Your videos are always educational and motivating! Thanks for another great one, mr. Scott :)

Probably too late for you to still read up on this video but I have a question Why did you connect CS on the FS312F-G to ground on the board instead of BAT-? Or why did you connect BAT on the TP4056 to ground with a 22μF while the datasheet says 10μF? (Also in EasyEDA you are supposed to mark not connected pins with the X no connect flag from the wiring tools)

can you sell these on ebay for us?

This is awesome dude! I've been waiting for something like this!

Thank you for the nice video Scott, makes me smile every time. Greetings from the "Bodensee".

I have no clue what is going on, but I still watch his videos.

I understand this video is intended for people to DIY their own PCB, but is it possible for you to put those PCBs on ebay or something to buy? I would be totally cool with spending a few bucks on a pcb like that (extra revenue source?) instead of going to the trouble to hand solder SMD components and hope it works.

Awesome I can't wait to see your gba sp build I been researching a lot on how todo this and fit everything in

Perfect Timing of this Video, the notification came out and watched this immediately really need this tutorial

So, we can use EasyEDA to design, publish AND build boards? By that I mean, their partner will sell and send the BOM to me?

What was the problem with first design? Would you care to explain your train of thought, why would the first design won't hold the +5 output(boosted)?

Very impressive and persistant work. Having to watch it a couple of times to keep up with you.. Thanks for sharing and for the pcb info too

Congratulations on this awesome project, it must have taken you many hours of research going through all the datasheets. Thank you for sharing and please keep producing these great videos.

Would you sell these fully made ?

Can this be used on 18650 cells too?

Excellent presentation of how to design test and debug. Keep it up. I really enjoy your videos.

You are amazing at your craft! I'm learning so much more from you than my professors at my university. And this video clearly explains how I'm going to approach my next project. Thank you so much for your videos.

I buy One 11.6V ready made lithium ion battery. It not contain any protection Circuit or balance Charging connecter so what I do for balance charging my lithium ion battery pack.

SELL THEM

Such a great video. You are truly inspirational man!! Keep these great videos coming!

Thank you! I have been needing a charge circuit for a while now.

Hi GreatScott, can you explain what the problem was with the first version of the board? In my last video I made a mini boost converter by putting an MT3608 on an SMD adapter board (see ukposts.info/have/v-deo/g2d9qmt9joqJmo0.html ). The output current I measured seemed to be quite limited and in my case the capacitors are too small. I also think the small 22uH coil I use is too light for higher loads. Thank you for making your videos. They help me a lot to understand things! +1

Aren't Li-Po batteries damaged if their voltage decreases below 3.2 V, meaning that your over discharge protection circuit isn't harch enough? :)

I just started using easy eda and it by far the most intuitive pcb design software I've used.

extremely cool of you to just continuing to put out high quality content for free!

Thanks for the video. I've considering buying expensive breakout boards for individual chips and bodging the whole thing together for a project that I'm working on, because I'm nervous about designing my own circuit board. But after watching this video, I think I have the confidence to get my own boards made. Cheers!

A big thing that helped me building buck/boost converters is knowing the ideal values of the inductor without needing to reference the datasheet each time (especially with general purpose switch controllers that might not have the specifics for inductors). I found an equation online for estimating the required value of the coil in a buck/boost converter, I then plugged this equation into a spreadsheet so if I need to build anything all I need is the input voltage, output voltage, frequency, and max current. This helps save space on the board and money in your pocket rather than going straight for the largest reasonable value. Not a huge savings unless you make a lot of boards but it's still helpful for making good buck/boosts. The value in henrys is L=((vin-vout)*vout)/(vin*Imax*hz*0.35). Thanks again for yet another awesome video Great Scott!

Awesome man. Stoked to see their board factory was fast and accurate. This has convinced me to give them a shot.

Fantastic video thank you very much for posting it. This has really peaked my interest in doing something similar especially based on the pricing of boards and components. Thanks again please keep it up.

Can't wait for the new version of the console and all the changes you've made to it. :) Awesome video as always!

So far I've ordered PCBs from Seeed, and Smart-Prototyping, but this... this beats all of them. Thank you for advertising them. Looks like I will order all my postponed PCBs at once tomorrow :D.

this is so cool to watch i hope I'll have the same amount of skill and knowledge in the future

!!!! DUDE !!!! !!!! YOU ARE AWESOME !!!! AN ABSOLUTE GENIUS !!!! Please keep up the VERY inspiring open-source tinkering, designing, innovating and help you give the world !! YOU ROCK !!!!

This is great! I had the same problem, trying to find an all-in-one board to power and charge my small projects. I think I'll order a batch of boards and assemble them myself. This is going to be fun!

Thanks for making the Gerbers available!

Wow. 3 in one board Edit: forgot to finish my comment lol. Anyway, I used your easy Eda schematic in a project of mine and added the traces to a single board. It’s impressive. Works perfect and now I have a complete. Present for my 10 year old brother. Thx man. This is the type of channel I like on UKposts.

Thank you greatscot. now it just waiting for parts. May have to review to soldering vid too. All the best

Nice work Great Scott!! Great project. Love your videos!

Very educational! If advertisement was always done this way I wouldn't mind it. I just created an account there and will be ordering my next PCB from there. Very convenient! Thank you!

ONE OF THE BEST THING YOU'VE EVER SHARED!!!!

Golden Axe!!! wonderful, spent hours playing it with my sister

THIS IS THE VIDEO WE'VE ALL BEEN WAITING FOR

You do great work, man. Keep it up!

Thanks for all videos you make. Please make a video on curcit for output of 5V and current of 2A

Built this using my DIY re-flow oven! It works great!! Thanks!!!

Your video editing skills are awesome dude!

Great job!! I will use it in my circuits! Thanks for sharing!

I have fallen in love with this channel

This is exactly what I needed! Thanks so much!!

Now a days you are earning very much as most of the video ofyour I am opening is showing ads great(keep it up) I am loving watching your videos

Exactly what I was looking for, even what I searched for!

Awesome job, and omg what a service!

Amazing All of your videos is amazing Watching from philippines 🙂

You are awesome man! As always, great video!

Thank you so much for your links, I've created an advanced solution out of them with possibility to measure the current and the battery voltage to monitor my system. Now i have to test it.

ohh god thanks Mr. Scott this was the charging module i was looking for

Thank you for sharing！I have made two of this mini booster for my Raspberry pi gaming console project！

Hey greatscott! You are best youtuber! You have clear Steps!

love all your works! nice job!

Cool! I love eatching your videos. I learn something new and I feel I have not wasted my time. You can only eatch so many 'Fail' videos and so many ' Why Japan.. Why?' videos in a lifetime.

geeze ultimate diy.... your own pcb board... im still trying to figure out how to wire existing pcbs i wanna play with... nice

Thanks! What an amazing project 👍 ☺

Im learning a lot from your videos, thanks !

Great video and circuit! Thank you for sharing!

This was good stuff as I'm wanting to do something similar myself. I'd need 2A output-capability, but at least you're giving me a starting-point. I love battery-powered gadgets and I've got a good selection of such, but I've never build any of my own yet -- I suppose this is as good a time as any!
