I FIXED this MATH PET by looking at it

This Casio Math Pet was bought "untested" from eBay. It has a weird fault where it comes on, but the game doesn't start and the screen is scrambled (apart from the clock, for some reason)
Let's fix it!
Hope you enjoy!
Steve

Stupid Math Pet. Pet.

[@zerocks88]

what's the extra account for ?

[@andersjohansson4734]

Math pet, math pet, math pet pet pet pet pet pet pet.

[@MCDbits]

So good at repairs that items now just fix themselves... Either that or they work through fear of a bodge.

[@warpath6666]

It's the magical powers of Dave at work here 😄👍

[@Vibropollo]

@@warpath6666 it's Dave's soul that can fix directly the chip at the quantic level

[@great_live_music]

Next time between buying it on Ebay as untested and when he'll receive the package, the item will be fine, brand new in box!

[@mikaelkarlsson9945]

Just for info: it's enough to lift one leg on a diode to take it out of circuit so you can test it properly. It also helps holding the thing while measuring..

[@StezStixMix]

Thanks Mikael, great tip! 👍

[@Miller4866]

​@@StezStixMix I don't know anything about electronic's what so ever but find all your videos fascinating (I'm addicted) please keep them coming they are great...

[@jbeef1289]

My favourite fixit video yet. I am now going to get out all of my unfixable items, open them and give them a good looking at. Thanks Steve.

[@sh4dowchas3r]

If that doesn't work give them a good stern talking to. You've probably already previously done that but not after the opening them up and looking at them as well.

[@DTGuitarTech]

Fixing things by only looking at them now! Will your genius ever end? Love your videos. Keep them coming!

[@StezStixMix]

🤣 thanks David!

[@Ea-Nasir_Copper_Co]

I think you might have just fixed a cold solder joint on that Zener diode. Look how dull the bottom solder joint was before you messed with it.

[@StezStixMix]

Yeah, that could've been it. Good shout! 👍

[@takashiemota9784]

The best thing about "bonus videos" is you don't have to edit a whole song! Plus Bonus Steve!

[@StezStixMix]

Yep, much more chilled on my 2nd channel. For now, at least! 🤣

[@lTinyl]

Your powers are getting stronger.. just to look at the thing... you fixed it!

[@Allerick178]

Well this was a funny short episode. Love it when you just look at things and then it works. Nice work Steve. Give my regards to Dave

[@stephencresswell4760]

I’ve fixed so many digital watches and calculators just by warming them up and playing with them. A night in the airing cupboard does wonders. I think a lot of things like this get left in cold and damp conditions. Get them warmed up and dried out.

[@danimourinho]

I didn't know you had a secondary channel. You made my xmas!

[@pedromimoso8804]

Well I did not know about this second channel. Very well, Steve! 😁

[@TheDemoniusX]

I love hearing you call things stupid, makes me giggle.

[@warpath6666]

Stupid comment section 😄🤣😄🤣

[@andy_rulz2000]

I remember having one of these as a kid, had hours of fun with it lol.

[@cosmefulanito5933]

For a two-legged component (like a diode), you don't need to remove it completely from the board. Just unsolder a single leg.

[@evilmissf]

She just needed a strip down and a good going over, Pet. Your hands must be magic lol dunno whether I was more impressed with your maths or the fix ? Canny video Hinny x 😆😅😂

[@simonlunt353]

It’s a bug bear when you don’t know what you’re have done but it’s a worker 🎉 marry Christmas Steve 😊

[@StezStixMix]

Thanks Simon! Merry Christmas to you too! 👍

[@vincefalchetti8475]

Hi Steve… i just became a monthly supporter of your channel. I love your videos btw, how to see sone new videos soon.

[@smiley800]

You gave it the 'Eye of StesStix'. Kind of like a medusa but different. Maybe it should be called 'Meth Pat'. Thanks for sharing. I really enjoy your content.

[@navinmarapana8704]

The blue worktop needs a wash!!!!!🤭😊

[@RandyDarkshade2]

Had the same thing happen with a modern stereo system. Display was not working, all I did was open it up, unplug every connector, plug them back in, put it back together and the display has worked ever since.

[@StezStixMix]

It's so weird isn't it, just shows you that it's always worth having a quick look at something not working, even if you're not too comfortable at fixing stuff, you can get lucky by re-seating a cable, or something similar! 👍

[@garymucher4082]

Some times being lucky is as good as being good... You've been in electronics long enough to know 'tronics are finicky at best. Thumbs Up

[@jcon6734]

I wonder if a button was stuck down and confusing it. Simply opening it up might have been enough the unjam the button and fix it.

[@seedmoreuser]

Yeah. Dirty contact. It'll probably lock up again in a day or two once the resistance builds up.

[@StezStixMix]

That's a very good shout! I didn't think of that, it's still working today but I'll try it again in a week or so! 👍

[@trevorhaddox6884]

3:27 The moment when the demon escaped. XD

[@valentinusaurelius2259]

Those are my favorite kinds of fixes. Open it up, screw around for a bit, and then it work.

[@wanjockey]

wow, how very interesting. Thanks for sharing.

[@jumpingmanjim]

I kinda want one of these now

[@robinsutcliffe-video_art]

Fuck, that thumbnail image had my creasing up, bravo!!

[@StezStixMix]

🤣

[@Max.Mustermann.]

this is the worst what can happen during an repair x) you fixed it but you cant reproduce how... ive been thought not to "guess" and randomly switch parts because of the "traceabilty" of an error and documentation for future PCB Versions and Soldering Settings :D glad it worked out even if you dont know what you did :'D

[@bollockszz]

Solid.

[@Inugamiz]

The power of Dave

[@StevenB-081]

Great vid as always

[@fixins]

Some things seem to need a good taking apart in order to work properly.

[@IamNotANumber]

Hooooway the lads and all that.

[@simonscott1121]

Im gonna guess that one or more of the buttons were "jammed" on, and you inadvertently fixed that.

[@SixtyDoesStuff]

I've "fixed" a number of things but just taking them apart and putting them back together. Sometimes a good cleaning just... resettles everything, I guess??

[@Wenlocktvdx]

This is how easy repairs are if you trust the force.

[@JeffreyGroves]

I suspect you cleared a solder bridge on that chip that looked dodgy, and that fixed the issue.

[@tonelemoan]

80s me is crying at that pronunciation of Casio.

[@coondogtheman]

I've recently had an MP3 player fail on me. I'm thinking it's the crystal because it freezes on the splash screen and just sits there. I'd like to get it working enough to copy the stuff off it and then send it to the hack pile.

[@ibrahimkocaalioglu]

Your Clark Kent eyes fixed it.

[@letttttttssssss_gooooooo]

Noice

[@samuraidriver4x4]

To test Crystals you need an oscilloscope and it's pretty easy. You should get yourself one, either a 50 pound analog one from ebay or go a bit more expensive with a digital one that you can hook up to a computer for recording. Just make sure that if you buy one from ebay that there is a trace on the screen.

[@DForce26]

I think it had a bug, but dave scared it away! :p

[@SixSixthSix]

Magic ⚡🧙🏼

[@kevinpayne3804]

I could clearly see a lot of dendrites around the microprocessor when you were looking around.. and one of them attached to your screwdriver as you were picking at it. Lead is well known for growing these spikes over time and short circuiting contacts between pads/traces.

[@TradieTrev]

@3:20 looks like a blob of solder is bridging the IC.

[@PowerPoler]

You have a second channel? 😱

[@MrThomashorst]

It's a thing, the world doesn't need😂 You should get yourself a Speak & Spell ... thats the right stuff😉

[@StezStixMix]

Yes! I need to look out for one of those! 👍

[@dak2]

Moved some dirt around

[@sudiptoborun]

3:19 , I saw a short between two pins of the microcontroller. Maybe I am wrong.

[@Jim_M_75]

You said Haway but spelt it Howay in the thumbnail Steve. Mixing up your Geordie and Mackem haha.

[@MikeSchmidt969]

I know this is a year old, but at 3:27 there may be a filament between the 6th and 7th pins that you knock off as you're doing the solid test. Could that have been it? I'm just an avid viewer and not an electronymacist, so I'm just guessing.

[@Lesarchivesdu-]

In fresh Pet is the word for ''fart''

Hi Steve I have a digital readout for my lathe and it's not working. Fancy a go at it?

[@mcCIDcombo]

I'd be fun to see you buy something untested being sold as parts, and when you test it, it turns out working perfectly fine. stupid seller.

[@StezStixMix]

That has happened before, I normally just swear and end the video, but maybe I'll post it next time! 🤣

[@mcCIDcombo]

@@StezStixMix The only time someone would curse because something's working as intended. 😂

1:44 you can’t set time if the slider is on „Time“ and not „Time Set“.

We’re all saying cold solder joint, so I’m guessing we’re correct?

[@BrunakoPAO]

Next step, just look at it without taking off any screws and get it to work. 😁

[@paulb4uk]

If only everything was fixed by just opening it up and screwing it back together .

[@sampahumeoli]

maybe it needed more solidness lol

[@rambofan1]

When you realize he has 2 channels 🤯🤯

Did you sing to it? That might have fixed it

"I can't set the time" he says, ignoring the huge TIME SET switch setting.
