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.
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.
@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

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.
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 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!
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.
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.)

Thumbs up young lady. It is really nice to see that after two generations, there are young peoples trying to learn electronics/programming/hardware from scratch. In 80s, I did not have the C64, I was a ZX-Spectrum guy, but my beginning was similar. Program in BASIC, in Assembler, make a simple hardware like 8bit A/D or D/A converter and attach it to the ZX-Spectrum etc. Later, I built the modem (300 and 1200/75 Bd) for ZX-Spectrum. I have this modem till today as a relic which remember me those days. Thx a lot for a nice video.

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
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.
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.
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! :)
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.
@@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
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.
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.
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!
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!
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!
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?
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.
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.
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. 🙂
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!
Yes I really enjoyed watching this thanks for sharing.. I had a Commodore 64 years ago loved it👍👍👍 Nice build job with your oscilloscope big thumbs up from me..
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 :))
@@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. :(
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.
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 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.
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.
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. :))
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 :)
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.
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 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👍.
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.
You are a genius! You saw a problem (keyboard input), bought a tool (in pieces and put in together) them fixed the C64 like it was no big deal. Awesome
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!
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.
@@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 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!
This used to be my go-to machine before the 386 arrived!! I was really uplifted to see it was resurrected!! Because seeing the young getting the hands on electronics and computing always a great thing!! We all need to know the nook and crannies of the machinery (beginning of them are a great one always) we use daily. Computers are everywhere today, in the edge of wiring too at times!! Great presentation and quite inspiring. Keep it up!!! Much love from Sydney, Australia.
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
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! 😄
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!
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.
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.
So proud that there are still young people enjoying vintage computers and electronics, and try to use them, fix them, and enjoy them!

That DIY oscilloscope is such a godsend for anyone wanting to get into board repair on the cheap.

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.

@@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
Good job Sayaka! Loved to watch this movie :)
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.
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.
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!
Wow, this video is truly amazing! I loved the dynamic soldering montage. I can't wait to see more videos on this channel! 😃
Ohhhh that blue screen brings back some 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!
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!
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?
Keep making content like this and you'll have sponsers knocking on your door and a silver UA-cam play button in no time!
Ottimo! 👏
Me lo guarderò con calma, anche perché immagino sia una storia a lieto fine.
That's the loveliest computer ever. I started learning everything on that machine!
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.
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.
Nice work on building the scope. I made the exact same one too. You even had the patience to film it all. omg
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. 🙂
Was able the find this oscilloscope for $15 preassembled. Thanks for the video!
The great bennefits of modern slavery.
Well done. Loved the video, especially the retro SID tunes! ❤
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!
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.😁
You take me back to my days studying EE in the 60s. Thanks!
Yes I really enjoyed watching this thanks for sharing.. I had a Commodore 64 years ago loved it👍👍👍
Nice build job with your oscilloscope big thumbs up from me..
Great content and production. You're a natural. I really enjoyed it. Hope to see more like this! Thanks!
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.🙂
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.
Watching people your age getting into electronics with such passion and finding joy in the old stuff is so enjoable. Count me as subscribed!
This is so cool to see your enthusiasm for vintage. Legend!
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.
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. :(
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 project! Thanks for sharing!
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 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.
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.
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. :))
$20 Scope! I gotta get one! Nice work too.
I had a C64 growing up along with a Ti-99/4A Great job Sayaka's!
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 :)
Yay! You have the official C64 Goat of Approval! Let's be friends! 🐐🎉
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! Thank you.
What a fun video! Well done getting it working!
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.
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.
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!
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.
You are a genius! You saw a problem (keyboard input), bought a tool (in pieces and put in together) them fixed the C64 like it was no big deal. Awesome
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$
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! 😊
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!
i've learned so much in just 9min. you make it look so easy!
Thank you so much, I'm glad you enjoyed my videos! 😊
This used to be my go-to machine before the 386 arrived!! I was really uplifted to see it was resurrected!! Because seeing the young getting the hands on electronics and computing always a great thing!!
We all need to know the nook and crannies of the machinery (beginning of them are a great one always) we use daily. Computers are everywhere today, in the edge of wiring too at times!! Great presentation and quite inspiring. Keep it up!!! Much love from Sydney, Australia.
Thank you so much for sharing your nostalgia and kind words! :)
This is awesome! Nice work. Love the video and your channel.
Wow, I really love your videos! Thank you, I really appreciate your comment
@Tronicsfix I just watched your newest video and now I'm here! Nice to see you praising smaller channels!
very satisfying fix video
The DIY oscilloscope is awesome. Now I also want one! Lol. Video was chill and super interesting. :)
great job and kudos for saving that commodore 64.
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
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! 😄
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?
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.
Those kits are a lot of fun, and good for practice. Several years ago I built a power supply and a multimeter kit.
Great video & impressive work
