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!

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

0:19brI can relate to this

Will you do a video on diy power supply kit too?
Comment from : @TopViewFar

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

good video Very instructive Rob

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

I didn't even know I needed a Koda fix but I feel SOOOO much better, thank you!!

What liquid did you use with the toothbrush to clean the flux? My board looks so greasy after all this soldering
Comment from : @crashvolt

I always cringe when i have to open those type packages with a razor knife So far, I haven't damaged anything YET!
Comment from : @rusty1187

Oh that's really cool I didn't know they made inexpensive oscilloscopes like thisI don't really have a use for it right now I don't think, but it would be fun to build
Comment from : @Luudite

Thanks for such an excellent, informative video :-)

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

I need some help with a retro handheld from 1997, I have it open now but the soldering is coming apart Any suggestions?
Comment from : @KarlsonTremorsII123

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?

Never get enough Kona!

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!

color codes on resistors
Comment from : @geoffreed4199

if olny I'd had one of these when i was a student
Comment from : @toxicplayer8089

Incredibly helpful surprise, I just ordered and received that same kit a day before you posted
Comment from : @Halo1Buff

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
Comment from : @mackenziebell9313

Neat stuff!
Comment from : @chefkdowg

@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
Comment from : @joshm3752

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!

hey adam, check your email sent something important

Comment from : @LegendSpecialist

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??
Comment from : @kliop00023

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 tbhbr(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)brThey still seem to be fun to solder together tho
Comment from : @Ziryu2

I use stick-tack putty, the sticky blue stuff you use to hang posters, to keep parts in place while soldering
Comment from : @CandyGramForMongo_

aaand bought one XD
Comment from : @radekvamowski8092

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
Comment from : @theannoyedmrfloyd3998

If I use rosin solder, do I need to preflux the joints? I never did before and it always turned out okay Your thoughts?
Comment from : @jimdavis6833

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
Comment from : @CaptmagiKono

I could not stop staring at the hole labelled 33v 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!
Comment from : @Skorn75

Quick question What temps do you run your iron at?
Comment from : @chaseholmes8229

I want one but I wanna do it all
Comment from : @pointedspider

Kind of a low cost? Its really cheap! Great for hobbyists wouldnt recommend for a business 😂
Comment from : @JuicyJakeRepairs

Yay Kona!👍👍👍👍👍👍👍👍
Comment from : @BeAGoodDoga

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
