In this video we will be having a look at a project created by one of my viewers. He created a remake of my power meter/logger project that comes with tons of improvements. Those include 3 channel measuring, WiFi, RTC support, USB measuring and USB-C compatibility. So how good do I think it is from a scale from 1 to 10? And should you consider building it as well? Let's find out!

Thanks to everyone for watching my videos in 2022😄 In the next video I will look back at 2022 and give you some insights about what is going on behind the scenes. I will also answer some of your questions; so put some underneath this comment so that I can answer them.
2023 will be quite a challenging year for me. I will turn 30 years old, the channel will turn 10 years old and I will be finally moving into my own house. There will be other personal challenges but I will keep them to myself😉 I look forward to the video production though because I still got tons of ideas and there are still lots of AliExpress products left to test😂
With that being said, I wish you all happy holidays. Enjoy a break, like I do right now and as always Stay Creative😁 I will see you all next year!
Congratulations!
Thank you for inspiring others to expand your work 👍
It was another year with great Videos! :D
Add a battery sensing circuit & program to detect 3.7v battery
What sort of automation are you planning for your new home?
You look way younger than a soon to be 30 year old btw! Happy holidays.
10:16 The TP4056 probably creates this noise because its battery terminal is not bypassed with a 10uF capacitor, as is recommended in the TP4056 datasheet. Should be an easy fix to get rid of this noise.
Came here to say the same. Ask me how I know… A tiny load resistor helped my project as well, though whether this would be useful likely depends on the ESR of the 10uF.
That's some useful information.
Love this idea of getting diy project from others and rating them. You should consider doing a mini series on them. I guess there are many people interested in showing you and others their interesting projects.
I agree. Was fun for me to do. Hopefully there will be more videos like this :-)
I agree, this would be perfect for projects that are put up on sites like Crowdsupply and the like.
Often, you'll see such projects featured on Hackaday etc. but more often that not, they just appear in the form of an announcement (or even "press release"), but without much further detail, much less an in-depth review.
It's also quite easy to miss those Hackaday posts, unless you visit the website regularly.
So having semi-frequent video reviews of interesting designs that show up there would definitely be something that I'd be interested in following!
@@greatscottlab Get a sponsor and create a contest.
@@yekutielbenheshel354 "This contest is sponsored by JLCPCB" :P
@@pixobit5882 Yes, something like that. Why not?
The ESP32-C3 comes in different packages just like every other ESP, but it looks like the design you got called for the MINI. The WROOM exists as well, which is what I use, and it has a slightly larger footprint but has easy-to-solder pins just like all the other ones.
Also, you forgot to mention one of the coolest parts of the ESP32-C3, it runs RISC-V cores instead of Xtensa cores, meaning compiler support is _way_ more plentiful compared to before
you code on arduino or esp idf?
If it has RISC-V cores does that mean it can run an os? I barely understand RISC-V tbh
@@alyxburke Almost anything can run an OS. Just depends whether anyone's written one 😁
@@alyxburke esp32 runs rtos on it
@@cooperised Important to note that some OS's require specific hardware features asside from the CPU. Linux, for example, requires certain memory controller hardware to be present.
Thank you so much for this insane video and all the the videos you made for us in 2022!
My pleasure!
@@greatscottlab I love LEDs like you! So can you make more videos about LEDs and motors in 2023?
Can't agree more!
A simple yet effective tip for SMD reflowing is to use an old glass-ceramic cooktop. Set it to about medium heat, place the PCB on and watch the solder flow. Its how I do all my PCB projects at my dorm where I cant really use a soldering iron, due to smoke detectors, but I can use the kitchen XD. Works a treat, if you are careful with heating.
that's sweet and I'm totally stealing the schematic to adapt for my own projects. thanks to you both 🙏
Go for it!
Your way of explaining electronics is so simple and very helpful
Great video! Thanks for your hard work in making it for us.
You are always making excellent videos,thank you sir. I'm 20 now and actually I begin to watch your videos from my elementary school time,though I didn't understand many of the English words at that time,I enjoy watching them.杜候君 from Hainan Island.
That's great!
Brilliant project! Fantastic work, dude! 😃
Stay safe and creative there! 🖖😊
And merry Christmas!
a great informational video delivered every time!!
Great remake of your older power meter/logger & thanks for sharing.
Could well be a debounce issue on the switches.
The repair tech side of me would be achingly tempted to get a scope out & see where the 2nd board is falling over.
Always blows me away the quality & ease of modern PCB design tools & PCB production places.
Wishing you & all your family a very merry Christmas, happy new year in 2023 with health, happiness & continued success
It would be interesting if this could start a huge project. This is the base device and depending on what you want to monitor, you attach optional boards. It would be pretty sweet for this to monitor USB powered, 12V, 24V, 48V, and mains powered devices. And any other commonly used voltages that i'm not aware of.
I made a similar comment above. But my idea might be a bit more involved 😁
There's a wonderful open-source SMU design that's been recently documented and released on eevblog and on RUclips by djErickson. Obviously a source measuring unit build would be a bit complex....but with the boards and parts all available, and the documentation so well done... He could definitely do it and make a video series on it. just be like assembling a complex kit...
It's one of the only things I've never really seen many people tackle a DIY affordable option. A good and somewhat affordable source measure unit would really be a lifesaver to a lot of techs and Labs who can't afford the $5009-$10,000 asking price for the entry level units.
Thanks for the video, have a nice year-end break!
Happy holidays!
10:05 what a cute puppy start-up :D!
A really useful device, maybe 3D printing a case for it with an integrated battery and a little code modification to display the battery percentage instead of the voltage (or both) would be quite useful. Happy holidays.
As much fun as receiving parts from LCSC is, I'm 100% sold on JLCPCB's SMT assembly service. It's so cheap with their coupons and saves so much time when you get your boards. I love it so much.
You are the only biggest RUclipsr I know that still likes to reply every single comments on your videos. 💌
I try my best up to 2 hours after the release of a video. But at some point the comments become to many to answer them all.
I definitely recommend switching from the Arduino IDE to Visual Studio Code + PlatformIO.
Also, the ESP boards can easily do OTA updates too, so you can do wireless deployments from your IDE to the board.
Yeah. I think PlatformIO is such an underdog. Would not like to do my job without it anymore.
Thanks for sharing your job!!!
Amazing! Al always 🥰🥰
Nice job, as usual! I'd be interested in seeing a video showing how you use your reflow station.
Scott, I use a toster oven to flow all my boards. Done over SMD 20 boards with no problems. 450 F for about 3 minutes.
Very nice project!
Nice updated to the original project. One trivial point is that the text on the silkscreen says it is a POWER LOGER. :)
An efficiency mode is a great idea for a multi-channel power monitor,, I hope someone adds this feature to the firmware, although its not hard to calculate from the numbers already given. Another good reason for multi channels is to monitor multiple power rails, as many devices have these days, or the power being used by different parts of a circuit when prototyping..
I read your comment that you were taking a break this year. Good work this year will wait for your next project next year
Thanks :-) Happy holidays :-)
Another interesting video. Thank you for sharing.
Hey
I remember your version of a Fireworks ignitor. I built a similar one at the same time. At the time I am 3 version further and it is much more advanced now (addition safety features in hw & sw, higher ignition voltage, larger range and 433 Bandwidth, resistor measurement,...). It seams like I can finish the basic version till this year's Silvester to test it out.
Love your videos!!
Thank you!!
Enjoy your holidays! You deserve it!
Thank you! You too!
I'm still stoked with that variable voltage convertor you featured off of Aliexpress... I had bought two as sometimes one will turn up broken and such a small price, I use one to power up the many broken laptops I am troubleshooting here, one input, one variable output no multitude of cables. The other is doing duty charging my 18650's, my dedicated cell charger broke and I just whipped the burnt out guts, fed in the wires, soldered the outputs to the cell charging common rails and voila... lithium cell charging on the cheap like a pro :D
I usually criticize Scott by sounding a bit arrogant in his videos about other people. But I must tip my hat about this revision. Anyway I got my bit of arrogance, since I'm watching his videos since the beginning, before I even considered RUclips as something, so it's cool to watch a video like this.
you can also reflow solder by putting the whole thing into an oven
in a hardware factory where i worked for a while that was standard practice (although those ovens were of course purpose built for that)
Hand solering and homereflowing the USB C connector can cause issues. Could have been the ESP32 was fine, but the data pins were not soldered properly.
Thank You for the amazing videos!
Thanks for watching!
hope this turns into a series
The cost is also reasonable. Keep Up Good Work M8
happy holidays . i would look forward to your new videos next year
Thanks :-)
good responsive buttons is surprisingly difficult, getting the timings just right, so many possible weird combinations of states.. really makes you appreciate object oriented programming 😆
Yeah I agree
Even commercial products have issues with this. The elevators at my work, when pressing the bottom, they make the tactile sound and the indicator behind them lights up, but it doesn't always stay lit, requiring you to press them multiple times until it sees that you pressed them
Hi, I'm a complete noob, could you explain to me what is the difficulty involved in getting buttons to work in both hardware and software? I was interested in this because I have a usb meter, tc66c, and sometimes a button doesn't work on several touches which leads me to believe it's faulty and other times it works perfectly
debounce, interrupt handling, purified code are the magic words my friend
Awesome RUclipsr for the tech minded.. Good stuff!
I have found a toaster oven works great as a reflow oven. I picked one up second hand from a Goodwill for use as a reflow oven.
Can always switch from esp32-c3-mini to the wroom version. Had much more luck with those!
You REALLY need to build you a cheap reflow oven! Seriously...all those SMD builds, it's almost imperative for you to have one...hand soldering with a reflow gun can damage sensitive components pretty quickly...a reflow is much more controllable
Find some of the controller boards online and find a cheapo IR toaster oven...and viola!
Keep em coming!!!!
I actually got an infrared reflow oven. But I honestly prefer a hot plate or hot air. Maybe that will change overtime.
@@greatscottlab With parts like the ESP32-C3, the oven will probably work a lot better. (Though a hotplate will likely also be better than hot air from the top.)
I've personally avoided the IR ovens, but I have a Controleo3-based converted toaster oven and it works pretty well.
It might be time to look into small 3D printer heated beads to use to upgrade your reflow station. They come in larger sizes than credit cards and some of the smaller beds are only 120mm square. The ESP32 may be in a tiny package, you can still look to see if the communication pins, power, ground and USB are actually getting to the footprint. I would not doubt somewhere else in the circuit there is a problem that a microscope can not see properly that probing the pin contacts will let you find. I agree for what it is that 8/10 is appropriate marks especially with the power issue. It would be nice if you mentioned a potential upgrade, possibly as simple as a slide switch, as an alternative than always have a battery. Stay safe, stay creative.
Is that heater the sort of thing you would use for smd components on say a motherboard PCB so for example capacitors didn't pop as they would if you used a hot air station? Do you have a link to it?
Hello GreatScott!, what do you think to use an Atmega32u4 instead of an Atmega328p? Would be the characteristics almost the same or would it be a big difference?
NICE... 2 questions... what's voltage and current limits and can you get one built up ?
Pretty cool! I imagine there are probably esp32-c3 modules that have castellated pads instead of that no-lead style. Note that the C3 had limited USB only for programming: is not like the S2 or S3 where you can do mass storage or hid.
can the S2 S3 be also programed via USB without any prior code on the ESP32?
Yes, they have a ROM USB bootloader
@@sanjikaneki6226 Yes, if you boot from the internal ROM they show up as a serial port on the PC and can be programmed very easily. Beware that there are also other differences compared to the "old" dual-core LX6 ESP32: for example, the S2 has a single LX7 core and no bluetooth, while the S3 has a dual core LX7 with bluetooth, but no DAC.
will not work using a capacitor connected to mass to remove those hearable freq?
This is just amazing.
I'm happy to see how you took another persons work, broke everything down and explained stuff from scratch.
As a fellow diy electronics content creator, i believe you did very well with the new board.
Merry Christmas and Happy New Year in advance Mr. Scott.
3:04 currently working on a heltec wireless stick lite. @greatscott is there any Video to this esp32 Basedow LoRa device that I missed or are you planning a New one? It's an interesting topic especially a point2point range test end LoRaWan would interest me very much. Grüße aus Wien
Thank you very much 🌺🌺
I have a question :- I used ESP-32 and programming it with Arduino IDE , the program was very simple it connected to WiFi and turn on and of some led. It is working but the temperature of ESP-32 was increasing, Why ?
Hey GreatScott, what is the difference between the Fnb48 and the FNB48s usb power meter? I have the fnb48, and my fnb48 looks identical to your fnb48s!
Special thanks to your viewer for making a Great upgrade, and thanks for making the video as well... I do find it a little ironic that you gave the improved version of your own project just an 8/10. So, I have to wonder, on hindsight, does that mean you only rated your own old project like a 6 or 7/10? (Which I kind of find a little humorous).
So, I have to say, it looks really good, and I agree with the idea to improve the code to add "Efficiency"...
Good stuff.
Enjoy your holiday bro🎉🥳
Thanks :-) Will do
is the design and codes available to everyone? is there anywhere i could download and make one for myself ?
Thanks for making the videos (:
My pleasure!
спасибо бро, хороший проект
Scott (thats your real name right? idk i forgot i am soo sorry)
I just want to thank you for getting all of us interested in electronics and other technical related things, you really are a living legend in this RUclips world.
And i also want to thank you for reading en replying to pretty much every comment. rare to see these days i would say.
Happy holidays, and groeten van België
Cheers
His real name i believe is Jeremy Pascal, he said it on old qna video though my memory its a bit rusty so i'm not really sure..
Keep up the good work
Thanks, will do!
Not even 1 second in to the video and already liked, love your videos
Thanks mate :-)
I wish microcontroller boards were made like RAM DIMM modules - with standardized edge connector easy to slide into the connector socket, easy to solder wires to bare PCB board, easy to upgrade/swap.
Tanks for your original project, I made 4 original power meter for my project, I am testing liion battery charging methods, and loggers ar essential part of my eksperiment.
Awesome. Thanks for the feedback.
You could, of course, just order the PCB with assembled SMD parts from JLCPCB. Their PCBA offerings are quite good, too!
And just like that, this project would be a lot more beginner-friendly, again. ;-)
It would be interesting to see if its possible to make a reflow hot plate out of a 3D Printer heated bed
I was just thinking that. One of my printers has a bed that is bare aluminium, and should be able to get to around 260 degrees (which is the temp most cheap solder reflow plates seem to use)
I subscribed to this channel half a decade ago!
GreatScott and ElectroBOOM are the best in electronics,
Hey GreatScott! (well I don't know your name)
what oscilloscope would you prefer to me ( and I mean a budget friendly one).
And thank you for your Great(Scott) videos.
How do you open the pcb and schematic.json files into EasyEDA?
Why the ghost voltage readings in your old power meter. Please help.
For those who want to build this project and can't upload:
I have assembled the project and i can't upload as Great Scott. The problem is when you first time upload, you MUST pull gpio9 (not gpio0) to ground. Which is connected to SELECT button on the board. Hold down it while connecting and try to upload. İf it fails again there is RX and TX pins on the board which are DC and RES pins of the LCD. You can also upload with FTDİ adapter. After the first upload (usb or ftdi doesn't matter) you can now upload anyway you want.
Hope this comment helps someone
Raspberry PI 4B version 1.1 had set the two 5k1 resistors incorrectly. They simply shorted both CC lines and connected them to one 5k1. In version 1.3 there are then two separate resistors for both CC lines.
How do you know all this stuff about electronics and the projects you make?
would be great to implement a discrete mosfet power path management for powering only by usb port. Otherwise a different lipo charging ic with power path could be utilized
Hey can we make same quality speaker like marshall speakers at very low cost or how to make super high quality amplifier
01:32 The smile is an appeal product on its own.
What pen u are using plz give link
4:20 Wasn't something like that a problem with the original Raspberry Pi 4 and required a revision to be properly USB-C compliant? AFAIK they had to use two different resistors to make it work properly.
I would love to see you make a video about a darlington array that is contrled by an adruino and van be run off off 5v intirely
4:24 Ah! I always wondered why some of my devices (RC radios for example, and other RC components which I suspect use cheap ESP32 components) will work when using a USB-A to USB-C adapter, but not a direct USB-C to USB-C cable. I suspected there was probably some component they omitted. Now I'm even more upset that it's because they are too cheap/lazy to include a couple simple resistors. 🤬
Glad I could help ;-)
It may not be a cheap thing but simply a "didn't test" or "didn't read spec" thing. All things that should have been avoided, though. My wireless earbuds case has this problem...
@@rpavlik1 yeah for me that would fall into the laziness category. Such a simple thing, obviously documented in a spec sheet, and they just… didn’t do it. If you’re serious about making a product and calling it USB-C and it does this, in my opinion you have failed.
@@rpavlik1 they might have test it with a non compliant usb-c charger that just outputs 5v all the time.
I always check the USB-C chargers what they output because i've seen one that just pumped out 20V without any handshaking.
@@swissfreek have you read any USB spec? It is really really long and complicated.
great video thanks ! and can i ask if you ever try to unlock laptop battery BMS board ? i cant find any datasheet or any useful video to just show they way to unlock laptop battery BMS board to i can use them on my project .(( AND its not just short + to + output or - to - output)) ! cus they all different board on different laptop but HOW we can knew what BMS board use what kind of switch ?! believe me i search all of internet and nobody make a true and useful video about this . i really thankful for your help
Hey, out of interest, why didn't you use jlcpcbs assembly service, I'm pretty sure they have most of those core components including the esp32-c3-mini-1 module. I've been using their service since it's release and I've never been disappointed
Thank you for all the amazing videos
I have an idea
Make a pick n Place project
I can put it on my to do list :-)
If all hobbyists do the same thing. Improving our word would be very cost effective.
good one Scott Great
Glad you liked it!
@@greatscottlab I did. but question, what should we do if we do not have a flow pad like you?
Don't get me started on CC resistors. So-called "professionals" like Adafruit, Pimoroni and Raspberry Pi manage to get it wrong. Congrats to the designer for getting it right.
Anyone know what was the cause of the bug in the original project?
Power Loger on the PCB. Damn
I find it so strange that I just happened to be planning a power data logger a month ago! This has happened more than once, it's strange how the projects sync up
Scott, Where can someone get the t-shirt you wear? I've hunted everywhere I can think of.
How to AC Milliamp measure in Arduino....???
Great stuff. I'm not a beginner but my fingers are not happy handling small things without moving. If there was a vendor who would do final fit and finish and solder assembly... that would be great. Until then, I'll enjoy watch your work remotely.
Could you make a flipper zero device
The dog 🐶 ♥️
It seems like I have a new project to make! I could adapt this PCB to make an electronic load part of an expansion, because I've been wanting to build one for ages.
LCSC shipping is getting cheaper again, and I can't let that opportunity slide
Have fun :-)
Can you make a project with a Router UPS?
Cool
sir how to make arduino oscilloscope ples one video we see youtube videos oscilloscope we make but not working it not working sir
There is also the esp32-c3-wroom version which is much easier to solder, except the themal pad.
Thanks for the tip.
@@greatscottlab but is also has another footprint and would need a redesign of the PCB
