Hi, in this video I bought another Amazon Returns Box from eBay! £50 for 50 items.
So what will be inside, will anything be fixable or will it all be broken beyond repair.
Let's find out.

Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.

That potentiometer you’re looking for on the gimbal is a psp joystick. There are psp joysticks with removable tops that are throughhole and smt instead of a ribbon cable. It’s the same one that knockoff joy-con usually use.

I was hoping somebody would have the answer to this in the comments. As there are not that many different models of mini/slim analog sticks around and products tend to use off the shelf analog sticks either from big names like Alps or clones from Chinese manufacturers, I figured it couldn't be that hard to find a replacement. I didn't recognize it as a PSP stick because the thumb cap is so different, but I guess the PSP's analog stick might've been an off the shelf model with a customized thumb cap.

@Jdbye Жыл бұрын

Even if the exact same model of analog stick couldn't be found, there's nothing stopping you from using a different analog stick if the resistance is the same as long as you can make it fit. A Switch JoyCon analog stick might work for example with some cutting of the plastic shell, not a perfect fix but a working product is better than a non working one.

18:00 The pinout looks like it lines up with the texas instruments BQ2404X battery charger, though that's certainly not what it is. There are a whole bunch of 10-pin DFN single-cell lithium battery charge chips out there, but you'd have to compare each one against the circuit that's hooked up to see if it's a viable replacement as they can be quite different from each other in terms of how they behave.

This is a perfect way to start my morning. It sincerely puts a smile on my face to wake up to a new MMV fix-it video. Speaking of video length... I for one love the longer format videos. I realize it would be more work... but if you want a longer video, but you get more views from a shorter video, maybe you can release a long version and a shorter version. Like I said, I realize it makes for more editing work... but I believe many of your long term subscribers would love to have longer videos. I was excited to see the runtime of this video, personally. No bandage on the finger anymore. Congratulations.

Well done, as always. What surprises me most is that these sellers must be taking a major hit re the postage costs, I'll guess at least £10 and probably nearer £15 for that box. The charge chip (EV4C) in the JBL speaker looks to be an NXE knockoff of the BQ24040 or BQ2409 charge controller IC (which JBL use in their other speakers), but, needless to say, do a pin-for-pin, makes-sense check before fitting one.

The last time I bought a box full of tech, it costed me more then 50 euros just for simple delivery (2 days deal) while the contents inside that box costed me 7 euros. Just to put into perspective wtf is going on. XD The very same reason why I opt out of buying things if A) is not close to me B) I have no means of picking it up myself or someone I know to deliver to my place C) it needs to have far greater value on the long run for me to bother invest money and time in it Sometimes even if it's given for free I refuse to take it since the transportation fee and time wasted on it doesn't make sense for me to jump into such things.

You may not have this problem with yours but incase you do I think this could be the cause it seems to be a design flaw! Good luck and keep the great videos coming thank you👍🏻

@albert_vds Ай бұрын

You can't test batteries with a multi-meter and conclude they are okay. The battery needs to be under load to read an accurate potential. Clip 2 alligator wires to a 100 omh resistor, 1 to each lead, and then clip 1 of the wires to the positive probe and the other to the negative probe of the multi-meter. Not putting it under load will give a higher voltage than the battery can give while under load. So it might seem it's reading as 1.5 volt but when under load it might give something bellow 0.8-1.0 volt, which isn't enough to run anything.

WRT that last fix with the hearing speaker, you could have used a cheap sewing needle/pin to provide the strength, then sealed the end projecting into the jack socket with mastic/hot melt or WHY; if you're unhappy using metal, there are novelty cocktail sticks made of plastic that would have done instead (with less strength ofc). It requires a steady hand with a jeweller's hand-drill to make the holes in the jack (esp centring), but I'm sure you're up to that with your microscope :)

If you would be able to reverse engineer however the components connected to the IC and the pins they connect to, I imagine there will be a drop-in replacement available from a reputable brand.

I reckon accessing the chip from the JBL speaker would be fairly easy, since JBL seem to have 1000's of them. It's probably pretty common. When replacing it on the PCB you probably wanna get a pre-heater, which is essentially a convection heater that suspends the PCB over the heat source warming up the whole board preventing localised heat from running off onto all the copper nearby. Then you can use your heat gun to solder the chip back on with some confidence you've reflowed the big ol ground plane underneath. Hard to check unless you have an X-ray machine handy.
