As a grumpy old man, it restores my faith in humanity that young people are developing insane skillsets and then using them to restore computers like the old C64.
The funny thing is that the cheap 20$ oscilloscope has more processing power in its CPU than the old C64 :D
True dat :)
But you can't play World Karate Championship on it 😀
@@Szejski Sure?
@@amigalemming Well, not yet. 😀
@@Szejski for 30 years now, every time I see a screen on something I always ask 'can you get pac-man on this thing?' (yeah, dad joke) but for the first time about three years ago I asked the operator of an industrial machine the same question and he looked over his shoulder and said 'yeah, check this out... whereupon he minimized the machine control software and brought up a games folder with... you guessed it... Pac Man.
Laughed my a$$ off
So proud that there are still young people enjoying vintage computers and electronics, and try to use them, fix them, and enjoy them!
There were times I could go to Radio Shack, get breadboards and components just down the street, play with projects until chickens wake me up. Today everything is online.
i think its called autism
lol @@SuperBranFlakez
@@SuperBranFlakez when the aliens invade, we will reply on the alien tech autists to save us!
@valnjes why proud? Im proud of things i achieved. or things my wife or daughter achieved. but i am never proud of things strangers have achieved . seems a weird concept. just like patriotism. why proud? please explain
When I was a kid, my dad brought a 64. He's gone now, but this brought back many memories, thank you :)
Since I was little, I've also been surrounded by retro computers and consoles because my parents used to collect them. So, for me too, it brings back old memories every time.I'm glad my video brought back yours :)
It always amazes me to see young people play with technology older than themselves. He makes feel better for our future. I'm a video game programmer and I often feel sad that young programmers didn't start with BASIC and machine code like I did. I'm also very impressed with the electronics knowledge that Eleonora already has.
I'm glad to hear that you're impressed with my video.I agree, It's fantastic to see enthusiasts sharing their passion for retro tech. 😊
Luckily, BASIC had a child before passing on and we still have _Visual Basic,_ so the _Beginners' All-purpose Symbolic Instruction Code_ didn't vanish completely.
I once wrote a shoot-em-up game in BASIC (some graphics needed ML) that ran on an Apple 2e. In many Computer Science classes, the ML writers are considered the "nerds". ("Nerd" is not quite an insult any more. Modern nerds wear glasses without tape, take showers, and some are no longer virgins into their 30's.)
Why would anyone write a video game in visual basic let alone BASIC in 2023?
It was never possible to write any decent game in machine code.
@@bonquaviusdingle5720 All games are written in machine code.
do you have any blog
That DIY oscilloscope is such a godsend for anyone wanting to get into board repair on the cheap.
I once buy osc like this, it was kit so some soldering was required. then it was 13 euros. I really should have two channel.
@@juhajuntunen7866 I bought a really nice 2 channel scope last year for around $100. The prices really have come down incredibly... and no soldering/troubleshooting required!
You can buy a prebuilt version of the same kit for $30 but that's not as fun as doing it yourself.
Or get a LHT00SU1 which is far superior for about the same price.
But how could one learn at least the basics to use oscilloscopes?
I'm a hobbyist car audio freak and also rc cars.
Is an osci useful for me?
Nice to see a young person into retro computers and electronics. Big thumbs up!
Thank you! I really appreciate your support. Retro computers and electronics have a unique charm, and there's so much to learn and explore in this field. 😊
retro gear is honestly the best equipment for new engineers to get into , the designs were so much closer to basic electronics, and wont be using loads of blobs or FPGA's you will get a better view into all aspects of electronics doing just what was done here.
Lots of gen-z getting into retro, why? No idea...
@@ingusmantBecause these devices are something that‘s simpler…
Yeah, they can worked on with basic tools, and components are big enough to be seen. I love retro electronic stuff.
it's good to see young people being interested in retro machines and understanding what's going in inside them, thumbs up!
nice indeed (and stay out of those fumes...)
At least you can understand the inside much easier and replace components with the SMT. Much harder with SMD.
I was going to say the exact same thing :)
Shame so many modern corporations continue to go out of their way to make repairing what you own as frustrating as possible.
The C64 was my childhood computer from 1985. It makes me really happy to see younger generations embrace the hardware. Please keep making videos on the Commodore 64!
It's superb seeing the younger generation repairing electronics from the past. You got a new sub
I owned a Commodore 64C when I was a kid. It's so nice to see people like you keeping these charming old machines alive. Thanks.
I think I'm around your age - I'm really glad to see there are more people obsessing over machines older than ourselves. It's a wonderful learning tool and hobby.
I'm also delighted to see people of our age showing interest in retro computers and consoles😄
I grew up with a c64 in my bedroom (was born in '79) and I gotta say Im a bit jealous of how capable you are with this when I never in my wildest dreams would have thought to ever take the thing apart. Cool video! Smart presenter!
Simply Mindblowing to see youngsters take up the Solder at this day and age. Alot of effort has gone into this video. Really appreciate it.
Great work!! If you get some more older bread bin C64s, you are going to end up needing to fix so many more problems. 😊 Keep up the great work!
Digital attic... digital basement... hmmm. I sense a collab.
Thank you for your kind words and encouragement! You're absolutely right, older C64s can indeed come with their fair share of challenges, but that's part of what makes restoring them so rewarding. Thanks again for your support! 😊
So you do watch youtube :D, cheers Adrian love your content .
Well done - so glad to see someone younger using and repairing C64s. Looking forward to more from your channel
I like the idea of build your own oscilloscope. Being an electronics engineer by trade, I work with this sort of equipment all the time , but I never thought you could get one as a kit
It's very limited, but for a beginner it's pretty good to learn the basics, i had modified mine to accommodate 2 channels, but still ended up buying an old analog scope and then fixing it which was much more usable
@@ShahZahid I noticed it was single channel and I did assume that it would have a pretty low bandwidth
Same,like the idea of really making one from scractch even more. I dont know what kind of hardware theyre using inside them but for $20 i just bought a 500mhz stm32h7 microntrontoller with digital signal processing instructions,which could do some nice fft, included a mini oled display and even came with a camera, 3x16 bit adc's upto 3.6msps, maybe thats the difference? Could you possibly turn one of these micronctorollers into an oscilliscope? Maybe use a couple of them for more channels. I was going to make an arduino one but ended up getting a 2 channel handheld but the bandwidth cuts in half when you use 2 channels(dso2512g), im guessing wouldnt be a limitation if you used more then 1 mcu.
@@mikejones-vd3fg the h7 would be good enough to make a somewhat usable scope also proper scopes dont use a microcontroller but instead a FPGA to accommodate the very high bandwidth and sampling rate which add significantly to the cost of the scope, but the real challenge and cost comes from designing a suitable front end for the scope, you need pretty high end adc's for a good scope.
ahh thanks for the clarification.@@ShahZahid
Wow, this was quite an informative video, and it was interesting to see you put that oscilloscope together !
I have a scope similar to yours, and I've only used it a couple of times so far. My girlfriend even found the video interesting!
Keep up the great work, and perhaps we'll see more from your channel, maybe?
You got the lottery getting into the algo. Excited to see where this channel goes. Please keep making vids like this!
Also it's pretty genius to save money with a DIY kit like this to check the C64 mobo, very clever.
Once again, it's great to see the next generation take interest in our older tech
it's good point to start learning how computer works . just on 8-bit compters
It warmed this old mans heart to see a young person restore an example of his first computer. Thank you. It would great to hear sometime how you came to be passionate about our digital past.
I'm impressed by the quality of your video for someone who started youtube just 3 months ago. I tried to make videos and I never ever came even close to that level. You deserve much more ! I wish you great success :)
Thank you so much for your comment! I'm really glad you enjoyed my videos. I'll keep working hard to improve even further, and I hope to bring even better content in the future. Thanks again for your well-wishes, it means a lot to me! 😊
@@Sayakas_Digital_Attic It looks like you're already taking off with that video, yt's algorithm noticed you, good luck !
Excellent video and work! Love the mini oscilloscope, and you don't need an expensive one to work on vintage computers. Thanks for sharing
Very true, to the point that one cant help but wonder whether there’s someone behind this young woman
As you were going through the process of building the oscilloscope, and resolving the issue with the C64, you reminded me of when I built a "Radio Shack ArcherKit Electronic Engine Analyzer" by hand soldering all circuit components and hand tuning the device during Christmas holiday in 1979. I bought and built that so I could work on setting up a newly available electronic ignition system I purchased that promised to save me on gas. This was on a 1970 Buick GS which was a gas guzzler. Saw about a 2 MPG improvement from 10 MPG and later introduced myself to the world of computers and programming on a Commodore 128 a few years later. I'm still working in the industry. Thanks for the flash back.
Wow, your experience with the Radio Shack ArcherKit Electronic Engine Analyzer sounds like a real DIY adventure. Thanks for sharing your flashback!
Cool story, cool car, cool computer!
Impressed by your video making, soldering and english language skills
Wow, a young lady with technical skills and passion for retro computing! What a pleasant surprise! Great job! These machines deserve to be kept alive :)
Europe has so many wonders...
I hate that word: retro. I've lived trhough it, so it's not retro to me. xD
@@hadeseye2297 Anything older than 5 years is retro in IT world.
The big bang theory crowd would have been ecstatic.
@@lukasgayer5393 there's a debate, some people say 10 years, some other say 15, etc.
Nice! What I like most is such a young person taking an interest in an old classic. Thanks for sharing. Not sure if a 64 exists that has never been opened.
Oh they exist. Got one with original seals last month, as it works fine i will keep it this way 😂
@@oliverochojski3561 I have a strip of those seals. They can be reproduced and applied. The seal means nothing. The only reason why I acquired them was because they shipped with an Amiga I bought on eBay a few years ago.
@@stephenbruce8320 I know about these seals, after Commodore Braunschweig closed there were many rolls of them around here in germany. But i bought this c64c with a blown power supply for 25 euros, i recognized after delivery that it was sealed, it was not mentioned in the advert. Advert only said no power light. So why should someone have resealed this machine and than sold it as spares or repairs for 25 bucks?
@@oliverochojski3561That's lucky, but most likely you'll have to open it and repair soon enough... these aren't the most reliable vintage computers.. haha
Go girl! Great Job!
Just a couple of tips to anyone trying something similar to avoid doing damage to the stuff you're working on:
1. ESD wrist strap and ESD mat are super good accessories to avoid killing ICs. If using a mat don't run the board with power while laying on the mat because signals might get grounded and result in weird behavior.
2. Get good wire cutters and try to pre-cut components before soldering them in place if possible. Wiggling while cutting could lead to cracks in the solder joint or in worst case the traces to separate from the board.
Thank you so much for your kind words and for sharing these helpful tips! 😊
Sayaka. Nice job. Im 49 and i used these computers in grade school. Its nice you have an interest in this. I also recently acquired an oscilloscope and am exploring the world of electronics.
I stumbled across this video and ended up being soooo impressed. You not only have amazing technical skills and understanding for someone of your age, but you also have maturity and patience. You have a great life ahead of you in technology. Respect! ✊
If the problem was oxydation, this probably build on top of the component legs and probably didn't affect the solder joints much. You most probably fixed it by disassembling it and re-assembling it (and using the contact cleaner) which cleaned/deoxidised the connection between the motherboard and the keyboard.
Still well done, as long as it worked! And your oscilloscope will definitely come handy in your hardware journey 😊
Same thoughts here. I repair C64 since 19 years and I had these situations. Someone flooded the keyboard and the connector was affected with small corrosion. After cleaning and plugging/unplugging the connector - everything started to work again. There was nothing to solder. I appreciate the work shown in the video by the way:) I have never had "cold solder joints" on any ICs in any C64, except for the power jack. Stay cool, good luck :)
Thank u eleonora from morocco
Keep doing what u enjoy
Great content! It’s fantastic to see young women into hobbyist electronics. I watched this video with my young daughter, hopefully it’ll act as future inspiration!
Early impressions really matter I think. All children should know that they can become anything they want. No one taught me that and I learned it maybe at 27 years old. I was taught only that money matters.
Had a good chuckle at the oscilloscope being delivered as a bag of random bits in a jiffy bag, quite inspiring that anyone can simply just solder something like that together, I had no idea. Great video!
I'm Italian and as soon as you started talking I recognized you're Italian too 🙂 ! Anyway it's AMAZING seeing a very young person have all those competences! Congratulations!
Being that a C64 was one of my first computers as a child, it brings a tear to my eye seeing people like yourself bring them back to life.
Well done on the fix. Bonus that it was just a bad solder joint. Those "short boards" are usually highly reliable compared to their breadbox predecessors. However, I would strongly advise relegating your original power supply to paperweight duty, and buying a modern one from Electroware (or a similar reputable dealer). Those old potted PSUs have been nicknamed the Commodore "brick of death", because when they fail, they go overvoltage and fry your C64. Hope to see more Commodore content from you in the future. -- JC
Thank you very much for your appreciation! You're absolutely right about the original power supply. I've heard about the known problems with those old ones, I'm definitely considering getting a modern power supply. Thanks again for your support :))
or you can replace the 7805 voltage regulator with a cheap buck converter, much cheaper and just as reliable ;)@@Sayakas_Digital_Attic
Wouldn't it just be easier and cheaper to add a MOV or shunt to the existing power supply or inline on the interior of the C64?
@@ikannunaplays Those bricks are potted in resin, and therefore cannot be modified or repaired. You *can* get a device called a "C64 Saver" that sits inline between the old power supply and your C64, which will trip if the PSU goes over-voltage. I'm not personally a fan of them because they cost the better part of a new PSU -- which you're still going to have to buy when your old one gives up the ghost. -- JC
@@BasicBitesCA The schematic for the C64 saver is open source and the parts are cheap, if she's got the ability to solder then this is a very inexpensive resolution compared to a new psu. Though I don't think such a complex and elegant solution is needed, but I also do not have a C64 to tinker with. :(
That's so cool, I've always liked dismounted things to assemble them myself.
High quality content and wonderful presentation. I first learned basic on a C64 and recorded my programs on MO2 audio tape. Wrote a math tutorial program for my younger neighbor to use and his maths improved thanks to my C64 system.
Thank you so much for your kind words and support! I really appreciate it. I'm thrilled that fellow vintage enthusiasts like you enjoyed the oscilloscope build. Your offer is incredibly generous, whether it's vintage computers or funds, your support means a lot to me. All the best to you as well!
@@Sayakas_Digital_Attic hahah I think this reply was meant for me! :) I'm ^^ up there ^^ 2 comments, tho> :D
Nice work, I bought the same oscilloscope, I recommend using a 9v battery, power supplies tend to disturb its operation for precision operations.
I'm glad to hear that you purchased the same oscilloscope. How are you finding it?
@@Sayakas_Digital_Attic Given the cost, it's an excellent product. I just had to build myself a decent tip because they supplied it with alligator clips, and get a 9.6 volt battery pack with a pack of 8 rechargeable 1.2 volt AA batteries, if I use the switch power supply low voltage frequencies are not detected due to too much noise.
Great video. A pro tip. First thing to do is to replace stock power supply unit. They tend to wreck havoc not only to themselves, but also to C64 as well.
I've seen these oscilloscopes before and wondered how well they work. 20 dollars isn't much of an investment but the time to put it together is. Thanks for the info.
Excellent video! That little O-Scope is a good tool to have for electronic projects. Many of us old timers, use them for quick testing. Tip: When you have to push hard on a probe, it is as you found: bad solder joints. Rather than removing and re-soldering, simple just reflow the solder. You will see it turn back bright and shiny again, and you can then continue diagnoses. A drop of liquid flux will also make it reflow even faster! Again, Great Video! :)
Thank you for your valuable tip! I appreciate your expertise. I'll definitely try the reflow method with the solder. Thanks for watching.
I became fascinated with computers with the Vic 20, C64, and later the Amiga. I am 56 years old self--employed IT guy working on failover clusters, virtualization, M365, Azure, immutable flash arrays, and much more via contracts with small to medium businesses.
Google works in mysterious ways to show me this great video 😁👍💖 I worked at a part time job for a full year when I was 14 to buy a Commodore 64 and worked another year to buy the floppy drive.
A kit build, combined with a repair video. Excellent!!
as a senior electronics engineer
you can use a multimeter to check the DC voltages and GND you do not need an oscilloscope
but nice video thumbs up good for you 👍
Nice work on building the scope. I made the exact same one too. You even had the patience to film it all. omg
Thank you so much for your work! Have a wonderful weekend! All the best from Berlin!
Just a tip that can make aesthetics slightly different: before shortening the pins, I like to pull the excessive solder by melting the blobs with the board upside down, one by one, so they end up looking like cones made by wave soldering. Your mileage may vary, depending on your soldering iron, temperature and solder composition.
Great video! I hope to see anything like MSX consoles in the future.
Thank you for the helpful tip! I appreciate the suggestion to improve the aesthetics by pulling excess solder before shortening the pins. I'll definitely give that technique a try.
C64 was the first PC I ever owned or used. It makes me really happy to see someone fixing this machine after so many years. Great video!
Well done. I am happy to see some from the younger generations get into and repair these classic computers. Thanks for sharing!
This video exercised a great premise, spoke clearly and simply about concepts completely new to me and made sense. The editing and subtle computer themed music really helped with the flow too. I’m fascinated to think that with well written and diagramed tutorials, learning exhausting tasks can be made easy. Thank you for the video!
Success! The C64 marches on. Thanks for sharing this
This was my first personal computer growing up. I loved it, and I was very lucky to have one.
I couldn't help but think that some brilliant electrical engineer came up with that €20 oscilloscope idea just to get students or hobbyists to get some soldering practice in 😄
That took a good amount of perseverance, what with the more complicated than needed schematics for the oscilloscope, but what great results!
You're right; it did require perseverance. But I'm really pleased with the results too. It's all part of the journey, right?
great job! keep in mind that Commodore's power supply adapters are quite old and tend to supply too much voltage. You should use a newer replacement as you might risk to fry some electronics (expecially the SID sound chip!).
Hi, thank you for the advice!🙂🙂
I agree with Loboolbo, original Commodore bricks are just pure junk, as the the 5 volt regulator will eventually fail, and sends too much volts 5 volt line, and will kill anything that takes power from that power rail. Repairing the PSU is not an option, because most (Like yours), are potted, and thus impossible to remove the bad parts.
If on a budget, you can easily modify the original ones with just a modern (usually router) 9v ac and (any old usb) 5v dc power supplies... there's a few videos on modifying the old one. At least for now, check your current power supply to make sure it's still close to 5v on the dc (the ac is likely fine).
@@BillyMartin4Lifethere's videos on how to remove the inside parts so you can re use the cables and box. I've done it on two of them.
@@BillyMartin4LifeIt’s such a shame that they fail “up”, so they damage the computers. Seems the reason is that it was cheaper to build them that way.
Thank you for letting us taking part in your repair journey. Please, do more of C64 videos! 🙂
I'm planning to do more videos on the Commodore 64 in the future, so stay tuned! Your interest and support mean a lot to me. :))
I had a C64 growing up along with a Ti-99/4A Great job Sayaka's!
Great job young lady, happy to see younger generations getting into retro computing and more importantly repairing electronics, bravissima.
I built one of these scopes when I first got into hardware, still going strong and I've used it to bring multiple products to market.
Really nice work! It's so rare to see people taking this level of interest in anything, much less a younger person digging into electronics. You have a bright future ahead of you!
Cute, nerdy, and an accent!?! The world needs more of this!
I am more impressed by the assembly of the oscilloscope than the repair 😊(still, great job on both🎉) Like Carl Sagan said, if you want to make a pie you need to create the universe first.
I saw one of those kits online a couple of years back and thought "nah, too much soldering", but you make look like it's not so much trouble and if it works then great.
There's actually quite a bit of soldering to do, but it's worth it. :)
Super helpful video, thank you for making it! I'll be putting this one in the bookmarks to share with folks!
Thank you!! I'm really glad you enjoyed the video. I follow your channel and I really like your videos, especially the one about the Commodore 64 on the modern internet, so I'm really happy that you liked it😁😁
@@Sayakas_Digital_Attic thank you! Can't wait to see what you do next on your channel!
So great to see a fresh face passionate about classic tech! Also great to see that you're able to achieve all this with limited resources. The Vic20 was my first computer and the C64 was my second, many fond memories!
Awesome build!
Beware those old Commodore power supplies. When they go bad, they send full voltage into the C64 and causes damage.
I'm aware of the risks, but currently, I don't have another power supply, but I'll definitely consider getting one in the near future.
@@Sayakas_Digital_Attic or you could make an overvoltage protector like the OpenC64Saver.
Wow, this video is truly amazing! I loved the dynamic soldering montage. I can't wait to see more videos on this channel! 😃
Excellent video all round. And in your second language. I have analogue and digital oscilloscopes but now I want one like you built too!
C64 :-) Oh my god, I worked on it in the 94? 95? What impresses me more is the young lady which can do all those things. Well done! The dinner is on me.
Impressed by your computer knowledge and enthusiasm; but most of all by your video editing and compilation skills! Excellent work!
Thank you ! I'm happy to know that you're impressed with my computer knowledge and enthusiasm, as well as my video editing and compilation skills.😁
This was one of the coolest videos I've seen in a long time. It reminds me of the passion I had for technology when I was your age. Please keep making more videos!!! Your future looks bright.
Wow I’ve wanted an oscilloscope for years but they always cost more than I could justify just for something I’d mess around with as a hobby. Also been looking for a project to practice soldering, so might have to pick one up.
Nice video, easy to follow, well explained, really good quality! It was a pleasure to watch, I don’t have a C64 but I feel like I learned a few things!
If you want something a little more fancy than this 20$ one there are PC oscilloscopes starting at about 200$
You need more heat ore a solder with lead. But for the first time - great. Some solder joints have cracks, we called them "cold solder joints" as TV technicians
Thank you for the advice! I appreciate your feedback and will definitely work on getting more heat and using solder with lead to improve my soldering. 🙂
Lat time I worked on one of those was in high school in 1989, Back then there were even TV programmes on teaching kids how to draw little patterns and work Lotus etc, I used to love Basic. Many of those kids now own and run the tech companies that make our world.
Wow, that's a great memory from 1989! It's amazing how technology has evolved since then. Basic seems indeed a fun language to learn!
Yay! You have the official C64 Goat of Approval! Let's be friends! 🐐🎉
You are doing the retro community a big favor by taking the time to fix up old machines like these.
Keep up the great work!
Thank you so much for your kind words and support! It means a lot to me. I'll definitely keep working on restoring these old machines. Your encouragement keeps me motivated!
My C64 is sitting in the attic. Has been for >30 years. Right before it went there, a 'friend' of mine dropped it from my desk, and the spacebar has been crooked ever since.
My heart aches for it. I have to get it to somebody who can fix it, one of these years. It's too bad you and I aren't in the same country, or I would've brought it to you.
Well done. Loved the video, especially the retro SID tunes! ❤
You take me back to my days studying EE in the 60s. Thanks!
The keys don't seem to cooperate - yes I love this. Perfect problem-solving description!
the scope build looks like fun. you could've done a video just on that! I'm subbed. Keep up the good work. I'm predicting your channel will grow quickly. So few young ladies into this hobby.
Great content and production. You're a natural. I really enjoyed it. Hope to see more like this! Thanks!
Keep making content like this and you'll have sponsers knocking on your door and a silver RUclips play button in no time!
Good stuff! Share with us more of your projects.
Keep up the great work. This system is embedded into my DNA.
that scope is really cool. Putting it together is just as fun as using it.
Great video quality!
Yes, the assembly part was the most enjoyable.🙂
That took a bit of intuitive thinking to consider re-soldering the chip when you found that you had to press hard on the pin to get a signal. Good job! Make sure to heat the pad and component wire then let the solder flow into the connection. Keep it up! 😄
Well done! Nice video.
I personally would get rid of the cardboard shield. It has no function anymore and only traps the heat inside the case.
Hi! I'm glad you enjoyed the video, and I really appreciate your advice🙂
I would disagree - it also protects the motherboard from dust and liquids. I've repaired multiple C64s and Atari XL/XEs, and the ones with the shields in place were preserved in much better condition. I never remove them.
If is is a metal shield, you might have a point. But those cardboard shields are useless.
@@joopidema Those cardboard shields do the same job protecting the motherboard from dust and spills. It is only about something being placed between the board and the vents.
This is so cool to see your enthusiasm for vintage. Legend!
great to see youngsters getting their hands dirty with screwdrivers, oscilloscopes and soldering irons... I hope your video helps inspire a new generation of youngsters to open stuff up and see what's going on inside!
Well done! I See you are full of passion for electronics and retro stuff (just like me), but you deserve a REAL oscilloscope, doesn’t matter wether analog or digital, it will give you lots of fun. I’ll look forward for the next video!
With the quality of the video and the repair i was surprised to see you only had three videos! Look forward to seeing what other content you make in the future.
Well done and congratulations on the repair! It's always great to see new people take up the retro-computing hobby! I was gifted a C64 for xmas as a child, almost 40 years ago now, and at the time little did I know that it would kick-start my lifelong journey into both IT and electronics. That C64 broke (and was repaired) a number of times. I feel privileged to have been able to experience that in my youth, and it's so lovely to see the next generation being able to share some of that joy too👍.
Thank you for the comment and sharing your story!
Good job 👍
I think the problem was a cold (cracked) solder joint though, rather than just corroded pins which usually do not reach into the solder. But the flux from the solder removed some of the oxides, too, helping with the measurements.
By the way, I had a soldering station with a tip just like this, and after some use the tip can fall off... so be very careful when using this 😅
Thank you! You're right; it's possible that there was a cold solder joint contributing to the issue. As for the tip ,you know, it happened to me once too, and I got quite a scare, so I completely understand. 😅
@@Sayakas_Digital_Attic
Yeah, it's a very unsafe design... what I ended up doing was connecting a cheap 40W soldering iron with the proper screw on the tip to the base station... The temperature control is fake anyways. There is no temp sensor. The circuit inside is essentially just a light dimmer which works just as good (or bad) with any old iron :)
I heart when vloggers use Kevin McLeod music too.
You are very courageous with that oscilloscope build! Soldering always scares me because I fear I'll ruin what I'm making or repairing. Nice troubleshooting and nice video.
As a 45-year-old linguist, artist and teacher of the German language, I can only say that, firstly, I am very glad that the world has such young and wise people, and secondly, that I watch this video with amazement, because I do not understand anything about this issue. Just watching this video is an amazing feeling.
I admire you calm logical approach and your tenacity. Most people would have given up at the start. Well done - you have a bright future ahead of you.
Thank you so much for your kind words! I truly appreciate your support and appreciation.
Well done young lady... very refreshing... keep on going, you are doing great 👍
Excellent job! One tip for soldering from and old engineer... focus on making the metals in the connection hot enough to melt the solder themselves and never touch the solder to the iron to melt it. When everything is hot enough the solder will melt and be pulled into the vias by surface tension and the vias will be completely full of solder on both sides. One second more of preheating the connection is probably enough. Another tip when building with through hole components is that the extra lead length is a heat sink. To make things easier and faster to solder, I trim leads before putting the components into the PCB so there is only 1 cm of extra length, solder, and then I use flush cutting diagonal pliers to do the final trim. Keep up your great work!
Thank you for your valuable advice and tips! I really appreciate your insights as an experienced engineer. I'll definitely focus on making the metals hot enough to melt the solder themselves, and I'll keep the tip about trimming leads in mind for through-hole components.
