Thank you so much for this tutorial. My first ever soldering project was a mess that never worked. Your tips plus the rosin pen helped me put this together in a working state. Couldn't believe it!
This should be good enough for signal tracing, watching data lines go low and high, measuring clock pulses... There's a lot in regard to computers this device can help with.
It definitely seems like it can be used to verify that a signal pin is outputting a signal, or if it's outputting a constant high or a constant low. If a dead chip conceals itself from continuity and diode tests, an oscilloscope can be used to expose it!
hey I just subbed I love the cleaning videos and I like that you don't fast forward everything that defeats the purpose this is like a cool version of asmr with the sounds and sights keep up the great content
New subscriber I’m working on the build presently. Everything worked except the test signal functionality. Then messing around I get only a white display and no blinking LED which I once had. I’ve changed components and checked circuits with no success but I will not give up. I’ve used a thermal imager and the 805 regulator up by the 9V input seems to be the only hot component. I’ve only started learning electronics heavy in the say last + year. I’m a retired aircraft mechanic and I initially started learning to fix and maintain and understand the electronics in today’s vehicles but my interest is just growing. I have other scopes but these small projects really help in building my skills. Thank you for sharing Artie 👍
Take a DMM and with power applied to the scope, start checking for voltage to the various components Start at the power input jack and follow the PCB traces outward checking for voltage as you go. Good luck
Oh that's really cool. I didn't know they made inexpensive oscilloscopes like this....I don't really have a use for it right now I don't think, but it would be fun to build
@0:30 do youtubers record themselves opening every package they receive? I want a video of you sitting down to open a box but it turns out to be mittens and a hat your grandmother knitted for you.
Back when I was building Heathkit TVs, O-scopes and such, I always used masking tape to congregate my resisters because I could fold it over the ends and mark each size as well as the "R" number of the circuit. Then I just pulled one out as needed. Plus, after folding the tape they weren't going anywhere if I accidentally bumped them while moving things around. Some of the time Heath did it for me in the kits and saving me time. Other times they just stuffed them in little envelopes with a kit number on it.
I just bought the same kit off ebay, sold as JYE Tech. About to start assembling it and was disappointed at first about the smd diodes and chips since I'm getting very familiar with it, then I saw the super small pins and thought , nah, it's ok those are done 😁
The waveform being jumpy at 33:48 is because the trigger level is too high. The trigger voltage setting should be below the max voltage of the signal being measured for a stable waveform display.
Hey, I love your channel!! I recently tried fixing my PlayStation 2, everything went fine until I needed to put the power ribbon cable back in place and now I can’t get it to properly fit. Do you ever do paid repairs? Thanks!
just started watching. I've debated buying Chinese oscilloscopes for electronic work I do in my spare time but I didn't know there was an application for game repair/console modding. ill watch full vid now
Are the j2 and onboard signal pins shorted on your board. Mine has no test post nor what appears to be a horseshoe shaped pin to use with the test clip.
I could not stop staring at the hole labelled 3.3v next to the chip you were testing at 30:00. Was that TP22? Even tho I doubt I could make use of an oscilloscope I'm tempted to get one of these to find out lol!
I blew out the input on mine with a generator that put out AC way more than I thought. I think 50VAC is the limit, but if I repair this one I'll limit it to 10VAC with back to back LEDs.
Why? You will destroy any high frequency waveform as well as clip off any AC component thereof. Not to mention youll have to add current limit resistance etc.
@@chantalheen484 Since I use this scope to check joule thieves, I don't care too much about distortion. I use a 10x probe for higher voltage, but for some reason the input opamp couldn't take the voltage spikes.
It's still recommended, especially with small diameter solder. You can get away without on larger joints, but for small stuff, flux is definitely a necessity. It'll make your life so much easier
can u make a video of all ur tools & this meter showcase/explanatory video as well as how various components work on the board may be so that viewers w/o seeing the tools b4 can pick up better??
Hey there! I got a board like this from eBay, but for some reason jp3 and jp4 have capacitors already on them, but the instructions say to jumper them, which is confusing as they technically are already jumped with the capacitor. Or am I wrong?
IS THERE ANY HACKER DOWN THERE??? The real questions is: "What are the limiting factor?" How can we improve the quality of theses ultracheap O's? -Getting a better probe? -Install metal shielding around some components? -Replacing the capacitor (or any cheap component) with something else? -Get a 9V battery instead of a cheap 9V wall transfo (like I do to save on battery cost)? I'm not an electronic guru, I only have some basic knowledge and TH-cam as a perpetual teacher. Alex from Montréal
Just checked my Amazon order from the other day and realized I bought a no-clean flux pen, hopefully I can use it for the time being and just clean with IPA afterwards
@@RetroRepairs Good to hear, those pens can be expensive! I'm a bit of a neat freak so don't really have to worry about it corroding anything since i'll be cleaning the components at least a few times haha
when needing an oscilloscope but not being able to afford one, Id just use my phone's line in(microphone) port, add some resistors to split the voltage (maybe add two zener diodes across the whole thing, for safety) and use a sound analyze app or smth, there probably already are oscilloscope apps out there tbh. (ik this only goes up to your phones sampling rate (typically only 48kHz), but thats quite alot cheaper than $25. plus Ive seen that those cheap oscilloscopes are quite terrible, even unusable above 100kHz) They still seem to be fun to solder together tho.
Where do you buy faulty nintendo games? If on Ebay then how do you search (which words) en which price is worth it? P.S. I asked a question about how to buy faulty gameboys in your last video, and I managed to get one for $15 with your advice.
Yeah, I figure that console and game repair does not require the use of an Oscilloscope that often, since it's generally a digital media. I would like to see some applications for it though, i'm certainly no expert when it comes to analog electronics, but it's obviously a dying breed now a days.
It could be helpful for testing ics, ensuring you're getting a clock signal, testing high/low, etc. A multimeter is still going to be a required tool, and i can't justify spending hundreds on a real scope, but this seems to be a fair option
are you a bit OCD I do not understand why you constantly clean the board after each item you put on it you can just as well we populate the board and once you are done soldering everything you can clean the board off I don't know why you're not using gloves because you would not get any flux onto your hands I have never put together many kits and that's what I do I put gloves on and then I complete the kid clean the board after soldering everything then I'm done. But you constantly clean the board it seems like a lot of wasted time and a lot of wasted that alcohol
Thank you so much for this tutorial. My first ever soldering project was a mess that never worked. Your tips plus the rosin pen helped me put this together in a working state. Couldn't believe it!
This reminds me a bit of being a kid and putting together model cars, something about the satisfying way everything fits. Great video as always!

Incredibly helpful surprise, I just ordered and received that same kit a day before you posted.
What timing!

I didn't even know I needed a Koda fix but I feel SOOOO much better, thank you!!
I use stick-tack putty, the sticky blue stuff you use to hang posters, to keep parts in place while soldering.
That's a neat idea! Thanks
At least this video showed up in my subscriptions!
I still can't figure out my my last one didn't. TH-cam just messed up i guess.
I didn't even get a notification. This was just there on my home screen

That was going to be my original plan, but the were a several cases where there was only a single resistor for a certain value.

Yay Kona!👍👍👍👍👍👍👍👍
Will you do a video on diy power supply kit too?
if olny I'd had one of these when i was a student...

I can relate to this.
I could not stop staring at the hole labelled 3.3v next to the chip you were testing at 30:00. Was that TP22? Even tho I doubt I could make use of an oscilloscope I'm tempted to get one of these to find out lol!
That was tp22. Possible that the directions had something lost in translation, and they were instead inferring i should use that test point.
I blew out the input on mine with a generator that put out AC way more than I thought. I think 50VAC is the limit, but if I repair this one I'll limit it to 10VAC with back to back LEDs.

If I use rosin solder, do I need to preflux the joints? I never did before and it always turned out okay. Your thoughts?
It's still recommended, especially with small diameter solder. You can get away without on larger joints, but for small stuff, flux is definitely a necessity. It'll make your life so much easier
Buy yourself a flux pen regardless, it'll make your soldering life so much easier.
I need some help with a retro handheld from 1997, I have it open now but the soldering is coming apart. Any suggestions?
Never get enough Kona!
can u make a video of all ur tools & this meter showcase/explanatory video as well as how various components work on the board may be so that viewers w/o seeing the tools b4 can pick up better??
better have tool recommendation videos as well lol

It'll be fine. Lots of people still do use it. It's definitely cleaner, but you still need to clean well once you're done
@@RetroRepairs Good to hear, those pens can be expensive! I'm a bit of a neat freak so don't really have to worry about it corroding anything since i'll be cleaning the components at least a few times haha
Thanks for such an excellent, informative video :-)
What liquid did you use with the toothbrush to clean the flux? My board looks so greasy after all this soldering.
99% isopropyl alcohol
I did think it would be some kind of alcohol but it's always better to ask. Thanks for the quick reply. Great vid.
Quick question. What temps do you run your iron at?
That would depend on the type of solder your using and it's melting point.
Hi Kona ❤️
the manufacturer should credit+payback this FREE tutorial video 4 their product lol
Neat stuff!
I want one but I wanna do it all.

A 6 year old put that screen protector on! All good
color codes on resistors.......
I always cringe when i have to open those type packages with a razor knife.... So far, I haven't damaged anything.... YET!

P.S. I asked a question about how to buy faulty gameboys in your last video, and I managed to get one for $15 with your advice.
Games are tougher, honestly you just have to get lucky. They don't come up much, and many are asking far too much, almost as much as working ones.

Kind of a low cost? Its really cheap! Great for hobbyists wouldnt recommend for a business 😂

aaand bought one XD
Nice
hey adam, check your email sent something important.
are you a bit OCD I do not understand why you constantly clean the board after each item you put on it you can just as well we populate the board and once you are done soldering everything you can clean the board off I don't know why you're not using gloves because you would not get any flux onto your hands I have never put together many kits and that's what I do I put gloves on and then I complete the kid clean the board after soldering everything then I'm done. But you constantly clean the board it seems like a lot of wasted time and a lot of wasted that alcohol
1. Spent rosin flux is sticky
2. Spent flux leads to poor quality joints
3. Alcohol is cheap
4. A clean board is a happy board
