Excellent! Thanks for sharing. This howto is extremely educational and badly need in the absence of any schematics or boardviews from electronics manufacturers. A shared repository of these single layered boardviews is badly needed. 👍

@nozynoz Год назад

Absolutely fantastic. Great job in presenting, kicad.

@irlstreamclips6016 Год назад

👍 Great video done at a good pace. I previously wouldnt have considered taking this on, but now if i had to I feel i could probably get there. Thanks for sharing your knowledge - I learn a lot here.

@timflynn3218 Год назад

Learned more about KiCad from this video than I ever learned reading about how to use it - Great job Richard!

@LarixusSnydes Год назад

Thank you for the hint of looking up a reference circuit to shape the symbol from. That's really practical :-) to get a readable schematic from the get-go if the chip is used in a default config. as it usually does.

@catgirllaura Год назад

I really Enjoyed this video, looking forward to part 2 Thanks!

@PaulaXism Год назад

Been doing this since I first started doing electronics back in the late 70's as no more than a kid.. Schematics?.. what are they.. All I had was the Mullard valve and transistor book printed the year I was born and a couple of generic tv repair books from a market stall.. Somebody gave me a Taylor meter they found in a shed when I was 14 and .. well. the rest is history.. Fixing guitar and pa amps for rock bands out on the road for years.. I'm the only amp tech in my town .. It's not hard.. some of the modern stuff is complicated but usually there is something similar enough to look at.

@midlifelab Год назад

A really useful video Richard, many thanks to Detlef and yourself.

@hopelessnerd6677 11 месяцев назад

Good timing on this video. I'm getting ready to do this on a motor controller that's not working right. If the board is single or double layer, you might also take a photo with a bright backlight as a kind of "x-ray" view, which might help with connections.

35:49 - Watching you guys work together here makes me realize that this task is not as daunting with a team: one on the software and one on the board. 39:48 - “Prior experiences” - I did not guffaw here; but, I did smile - does that count as previous experience?

@paparoysworkshop Год назад

Very interesting video. My only question would be: If a person did want to make a second unit, then they would need to acquire suitable parts. Using inductor symbols to represent the transformer is fine for a schematic, but to actually build this power supply, you would need to find an actual transformer with the same (or similar) characteristics. And of course, that transformers pinout would need to be used. If all you want is the schematic, then none of that matters. I look forward to part 2 to see how you address this. Or if you address this issue. In the meantime, great video and thank you for making it.

@LearnElectronicsRepair Год назад

Of course you need the suitable parts to reconstruct the power supply. The scope of this video and part two is primarily how to reverse engineer a schematic and secondly how to make a gerber file to duplicate the PCB.

@yenaurapourtoulmonde 3 дня назад

Quite interesting. Now looking for part 2 scheduled for "next week": did find it. Please could you be more concise : video really starting at 8:40 and could be four times shorter. Due to my maaaany projects my time is precious...

Is there a link to part II ? Waiting to see how you convert the pcb tracks to schematic rats nest.

@laptopDoctorKZN Год назад

Hey.

@badgerfool1980 Год назад

Definitely going to have a try of this! As someone else mentioned an open source repository of reverse engineered schematics would be a great idea, I just have no idea how you would validate their accuracy. If anyone knows how to contact Louis Rossman I believe he is doing something similar but way more ambitious with repair guides for apple (eew) boards so may have some thoughts.

@LearnElectronicsRepair Год назад

This method makes it much easier to ensure your accuracy - you will see how to get it right every time in part two

@LearnElectronicsRepair Год назад

@Mr Guru I do agree what you say about people thinking a schematic is a magic bullet, and you already know how much I teach repairing without schematics. It does take a particular mindset (in particular, patience) to be able to do this sort of thing. If you are the sort of person who thinks untangling a box of cables is a 'challenge' rather than frustrating, or finds sorting a big heap of nuts, bolts, screws etc into a compartmented storage box therapeutic or even relaxing, then this sort of work is probably for you 🙂

@TheAnimeist Год назад

The best way to get Louis Rossman's attention is to tell him that you are from the Brooklyn department of waste management, and you need to collect a bill. :) Say, you wouldn't happen to be the same guy that badgers Onewheels, would you?

@jackr-jm1qk 6 месяцев назад

I couldn't figure out how you managed to 'sreach' the PCB to match the footprint of the DIL-8 package. In the video you get the DIL to disappear and the PCB to enter a tranform function but it's not clear how you did it.

@reynaldofigueroa3372 Год назад

i suscribe to your channel, it seem what you are doing is very interesting, where are you in the USA.?

@LearnElectronicsRepair Год назад

LER is produced in Gran Canaria (island) Spain, though i am originally from the UK (and Det is from Germany)

@pdrg Год назад

Does the footprint for the dip8 need to be flipped, or are we pretending we're placing components on the top side of the board and can see through it like an x-ray?

@LearnElectronicsRepair Год назад

We flipped the board earlier in the video

@LearnElectronicsRepair Год назад

@Mr Guru Which also need to go onto the 'correct' side of the board 😉

@jscruffins8767 Год назад

any tips or links to videos that anybody knows of, which are helpful for identifying mystery inductors w minimum setup (i.e. no more than sig gen and scope)?

@LearnElectronicsRepair Год назад

An ESR meter (a real one not the feature built into component testers) will measure inductance though you need to use just a little math to convert the ESR 'resistance' reading to microhenries. I demonstrated this here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bMUzTGnvrbU.html That will not tell you all you need to know in the case of power inductors, but it is a start.

@LearnElectronicsRepair Год назад

@Mr Guru The cheap component analyzers can measure inductance and they are extremely useful, if not indispensable. However I have found and proved that a 'real' ESR meter is far better at measuring low value inductors such as those found in VRM. Probably both tools are something you really should have. The component tester function of the DSO-TC3 I reviewed recently proved to be far more capable than other cheap ones I tried (even with small inductors), and it actually surprised me just how good it was. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JpISM7g9Ff4.html I am happy to recommend that one.

KICAD IS AWESOME !!!!!!!

@LarixusSnydes Год назад

Yes and no. That you can use such a mature tool free of charge is awesome. The UX however is non-intuitive to me and don't get me even started about some of the more obtuse error messages. Good UI/UX designers are quite rare so I'm grateful that it is at least functional. If I was a developer I would have offered suggestions on how to fix some of the issues, but I'm not.

@TheEmbeddedHobbyist Год назад

I like KiCAD but it does give me a hard time every now and then. I'm sure that sometimes an error makes it lose a link in it's database and from that point on it's better to stop and start again.

@LearnElectronicsRepair Год назад

@@LarixusSnydes The 'loose' relationship between symbols and footprints in Kicad does make it rather well suited to what we are doing with it, as you will see more so in part 2 later this week. I hear what you say about the UI though, this video required quite a bit of editing to keep Det looking calm and collected throughout LOL 🤪
