Learned one more awesome trick from Sorin the other day - set your lab power supply to 0 volts to use it as a voltmeter .

Hey Galaga, are you okay?

Stumbled upon my old GoPro WiFi Remote and it won't turn on - no wonder since I've used it last before COVID started - not much to film during lockdowns or war in your country.
Decided to try to save it and it was really easy - just open it by removing four T6 screws and then set the PCB free by removing one PH0 screw. Charge the battery directly with 4.2V from a lab power supply and you're good to go
Found a small #easteregg on a Raspberry Pi 5 while replacing a dead Ethernet port .
Frankly speaking I never really thought that Ethernet port is not just a traditional passive port and that it has something that can literally die inside.
It took me quite a few hours of checking and changing all kinds of other components linked to it, but now I know .
Oh, man, I guess I got myself into some deep-deep-deep waters with this - absolutely insane amount of information to learn, but curiosity wins again and I love it .
P.S.: was really happy to find out that initially project website used to be Svod.od.ua - arguably the best programmer on the market originated in Odesa, Ukraine .

I have two systems that need to be re-capped: an NES front loader and a model 1 Genesis. My soldering experience thus far has been limited to changing backup batteries in carts.
What do I need to know before attempting a re-cap? Can I get by with just using desoldering braid? Will ones of these (the Gen or the NES) be easier than the other to start with?
New microscope polarization ring light arrived today.
Until now I used iFixes iL37 and it was a huge improvement over the non-polarized lights. But the picture was pretty poor in terms of color and dynamic range (check photo 1).
Today a new Mechanic LS720+ light arrived and it is way less bright than iFixes, yet more than sufficient.
However it provides a much better picture quality and I can see marking on the chips I simply could not before (photo 2)
Got a Pi 4B with a torn CPU the other day. Removed the lead free solder residue and discovered that a few pads were torn. One of them is important, so had to repair it with 0.02mm wire. I still can't believe it, but it works .
I recently set my own record - fixed 11 #RaspberryPi boards in 24 hours .
And while at it I tried Mechanic M35 Nano Flux.
I really like it and will be using it from now on - it is 4-6 times cheaper than flux I used while it is almost as good + it cleans much better.
No smoke. Decent BGA work.
Two suggestions:
1) use the thinnest needle you have to save it
2) use a needle cap - this flux spills all over the place
And while my Pis update - I'll tell you how I saved another Pi 5 today.
It arrived brand new with no shorts, all voltages present.
No missing components.
No broken or burned traces.
Nothing shows up on UART. Customer bought it like that.
So I reflowed the CPU, RAM and RP1 to be on the safe side and right after that I noticed this little prick - a 10K resistor simply got cracked in half .
Pure luck .
Hi, #fediverse. Let's try to get #fedihelp with #electronics and #electronicsrepair.
I need to figure the marked component on an Nvidia Jetson Orin Nano carrier board (model P3766) because it has blown up.
If you can - please tell me what marking is there or what that component actually is. It had something like TT written on it - that's all I could see.
Thanks a lot! (boosting is appreciated as well )
One more. This Pi got so hot it left melt marks on the enclosure . Eventually CPU died.
It was one with MXL7704-P4 PMIC so that CPU I tried to install earlier worked perfectly fine.
So indeed it seems like different CPU chips are meant to work with different PMICs.
P.S.: It amazes me how these days reballing and replacing a CPU feels like a quick and easy job - something that was unthinkable just a few months ago .
Oh well, today I bought a dead Raspberry Pi 4B 8GB for repair.
I checked 3V3 at the post office and found low resistance - surely a dead PMIC I thought and was too lazy to check the coils around it. Turned out to be a dead CPU.
At first I got a bit upset, but then I remembered that I wanted to try replacing a CPU on a Pi for a while.
So I did. Turns out it's not that big of a deal. Though I did it twice - here's why... —>
So my #Bosch #Intuvia display started to fail to wake up the battery/motor on power on. Its still possible to press the button on the battery to wake it and the motor up but... eh.
Now it got a new smol LiPo. It lasted 25000 km / 1990 hours / 10 years so not bad.
25007 / 1990 hours - thats way too slow? Yes, it counts the time on the charger as well so this is ride time + charge time = total on time (minus the time where I charged the battery directly / not in the bike).
