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
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.
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 :)
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.
It's superb seeing the younger generation repairing electronics from the past. You got a new sub
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!
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.
Well done - so glad to see someone younger using and repairing C64s. Looking forward to more from your channel
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.
A girl fixing a C64. You would have been my dream 30 years ago 🙂 Kudos to your work!
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.
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 .
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.
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
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.
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!
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! ✊
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
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
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!
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.
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
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!
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. :))
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?
Well done. I am happy to see some from the younger generations get into and repair these classic computers. Thanks for sharing!
Great content and production. You're a natural. I really enjoyed it. Hope to see more like this! Thanks!
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.
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.
Wow, this video is truly amazing! I loved the dynamic soldering montage. I can't wait to see more videos on this channel! 😃
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.
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!
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!
That's so cool, I've always liked dismounted things to assemble them myself.
Well done. Loved the video, especially the retro SID tunes! ❤
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!
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!
So nice to see someone so young bring back to life our beloved old tech!
Awesome! Looking forward to seeing more. Still have my C64 from when I was a child many years ago
This is so cool to see your enthusiasm for vintage. Legend!
Great job young lady, happy to see younger generations getting into retro computing and more importantly repairing electronics, bravissima.
A kit build, combined with a repair video. Excellent!!
Thanks for showing us the tools you used, your process, etc. Very solid.
Thank you so much for your work! Have a wonderful weekend! All the best from Berlin!
learned a few cool things from this. thanks! also I love the music :D
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.
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.
What a fun video! Well done getting it working!
I have that same exact oscilloscope! Love that little thing. I’m impressed with how you fixed the commodore. Thanks for sharing!
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 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?
I'm so glad i found this channel!!!! Awesome work.
Excellent work, miss! Keep on keepin' on!
Nice work on building the scope. I made the exact same one too. You even had the patience to film it all. omg
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.
Excellent video, well presented and throughly enjoyable, thank you !
Those kits are a lot of fun, and good for practice. Several years ago I built a power supply and a multimeter kit.
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.
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.
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.
this was really cool. great job!
Great video! Love your presentation and editing skills! Subscribed!
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.
Hi, Your videos are very good, you explain things very clearly and it's great that you
are doing things on a budget as I believe this reflects how most beginners would start.
Your camera shots are also clear and show everything that you are explaining.
Thank you very much!
Great video and kudos for being creative and resourceful!
Retro computers can be fun and a great learning experience!
Go on, young lady! The future is yours!
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.
OMG this is great! Looking forward to more cool retro projects from you! Subscribed.
Amiga will always be in my heart. Nice video, great skills
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. :(
Keep making content like this and you'll have sponsers knocking on your door and a silver UA-cam play button in no time!
I love disassembling stuff! I've considered buying this oscilloscope. thanks for the video
Cute, nerdy, and an accent!?! The world needs more of this!
Awesome video!! Very well done, great job explaining everything!
Thank u eleonora from morocco
Keep doing what u enjoy
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.😁
now I want to build my own oscilloscope. it was amazing to se you were able to do all the soldering without having the best tip.
hoping to see more videos like this in the future!
Absolutely fantastic vid, such inspirational DIY effort. Subscribed!! Looking forward to more!
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 :)
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.🙂
Great project! Thanks for sharing!
That is a great little oscilloscope, I have one myself for all my small workshop projects. I also obtained the Perspex case for it to keep everything protected
Building a tool to fix a tool is very cool. Impressive work. Thank you for sharing this video.
Thank you so much for your kind words! Building a tool to fix a tool can be a challenging but rewarding process. I'm really pleased to hear that you found it impressive. :))
very cool show sayaka! i recently purchased the same oscilloscope kit, but have yet to assemble it, so it was nice to see your experience. also its very cool that you found such a beautiful commodore 64 - the new version with the angular keyboard which i find an improvement over the old beige case. also - very nice work on the circuit analysis. well done! ✨
Thank you so much! I'm glad you enjoyed the video and found my experience with the oscilloscope kit helpful.😊
Excellent work! Sayaka! Good job!
You diagnosed and fixed that super swiftly!! Great video to show people incentive to get an oscilloscope, shows exactly what it might be useful for and even that they're not as expensive as you'd assume. Awesome video!
Very thorough diagnosis. Good find and great job assembling the oscilloscope.
@@martinkuliza Interesting. I normally diagnose with a multimeter, she did it with an oscilloscope.
She checked the pertinent pins etc. What did she not cover?
@@martinkuliza Point taken. I concede.
@@martinkuliza Actually, I didn't explain myself well. When I say 'from my collection,' I mean the collection that my parents left me. Since I was a child, I've been surrounded by retro computers and consoles because my parents used to collect them. However, they no longer use them, so I've been repairing and tinkering with all these consoles and computers for about a year now. But, of course, most of them I have no idea where they came from or if they work! I'm still at the beginning, and I can understand that I might not come across as spontaneous while speaking. The truth is, I'm a bit camera-shy, but I think I'm getting better at it, at least a little! The video is not at all promotional, which is why I didn't mention the name or the link, and I haven't published it!
Keep doing these as long as you find it interesting and worth of your time :)
That’s such cool little kit! I might have to pick it up!
Great video! I like how methodical you were - documenting every step of your thought process, and working with proof and expected outcomes rather than leaping to a conclusion. Well done!
It's great to hear that you appreciated the video! Thank you🙂
I love your work. Thank you for keeping Old Tech alive. I love Sam's Journey on the C64. I have a Raspberry Pi 4B 8GB in the Vilros Keyboard Touchpad hub. It's like a Stealthy Black C64. I run Berryboot Operating Systems. Great job. Thanks for the video.
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.
You take me back to my days studying EE in the 60s. Thanks!
I had a C128 growing up. And seeing you work on a C64 is awesome!!!! I can see it was the newer style than the original C64.
