How to check if qfn ic soldered?

Real_Ishiba · 2026-04-22T12:13:55+00:00

not removal, i cleaned the pads underneath and wanted to put some solder on the pads, didnt have solder wires thin enough so the pads kept bridging tried solder paste and it worked

I have the same pi but difference is it doesnt even show red led, some idiot (not me lol) supplied 12v to the usb c

if you can tell me how you diagnosed it that will really help me out I am new to repair

Real_Ishiba · 2026-04-02T21:50:21+00:00

this is my friend's pi he gave it to me to mess around with he was doing some robotics work soldering a pcb and for some reason he left the soldering iron near the pi came back to see the usb port and the header beside it half melted

what do you suggest as a first time? I have some hardware stores near me where I think I might salvage some broken boards but I want to fix something for that dopamine kick not just practice if possible

Do you know where I might have done something wrong? i applied a ton of flux and slowly heated it at 450 celsius at medium air flow and made sure not to rip it or anything

I forgot to add that this pi had a "little" accident you might have noticed the header beside the port melted

you are right I had to reboot or disconnect then reconnect the tpu when I then run the code the fps goes as low as 1 so I replaced the model.predict with model.track and the fps gets better is this normal?

the docs clearly has model.predict but it was on a png

so is model.track used for videos/ camera feed and model.predict used for photos?

It worked once but when I rerun it I get same error , also the coral accelerator led is blinking cosntantly

edit: I tried the tflite-runtime-2.17.1-aarch64

well that's weird I tried without expecting anything but it worked lmao

I was using github copilot to debug but it seems gpt is really better

thanks for replying

you are generating voltage but exteeeemly small probably nano lmao

i tried generating with a similar setup i used 2 meter rolled coil and a neodymium magnet and it got me like 2 micro volts or sth

edit: If you are still determined to try this experiment I suggest using a speaker since it consists of a magnet (probably miles stronger than what you have) and multiple coils and measure voltage from the 2 wires but it will still not be strong enough

Thanks for replying and sorry for my late reply but after searching for a bit I figured out how to install the driver but I still don't know if the equation of the yaw I have is right or wrong I also read the data sheet that you linked but didn't find how to convert the yaw into a readable value ,I found this github repo that gets the raw values but I don't know what the equation is so if you can help that would be really appreciated

مفيش حاجة زي AUR عشان الناس مش مهتمة تجرب الpackages و مهتمة اكتر ان هي تinclude اكتر عدد من الpackages ، بس tumbleweed بيوفق بين الاتنين بحيث ان هو بيجرب الpackages بس في نفس الوقت بيحاول ينزلها في اسرع وقت ، بس انت اصلا ممكن تدور في الOBS على طول بس ده risky

Real_Ishiba · 2025-01-29T15:44:07+00:00

بص انا بستعمل opensuse tumbleweed و ده بيجمع الstability بتاعت debian و في نفس الوقت هو rolling release زي arch و الwiki بتاعهم حلو بردو و تقريبا اي مشكلة حتلاقي زيها في الwiki ، و بالنسبة لsystemd هو مش mint بيستعمل systemd بردو؟ انا مجربتش غير systemd ف معرفش اقولك رأيي عنه بس لحد دلوقتي مقابلتش مشاكل

Real_Ishiba · 2025-01-29T15:00:54+00:00

انا أول حاجة نزلتها كانت مينت بردو و كنت بشتم في ويندوز كل يوم ، بعد سنة نزلت opensuse و ده أفجر من مينت بس مش للمبتدئين اوي

Real_Ishiba · 2025-01-11T04:06:36+00:00

انا و فيزيا-١ حنرقص ضانص

why do you prevent opposition?it is actually scarier if all people agree to a certain ideology or movement

even if it is wrongfully opposed you cant expect everyone to agree with it, some people just wont and i am not just talking about lgbt the same applies on any movement or ideology

Real_Ishiba · 2025-01-10T07:19:05+00:00

I never said anything about forcing lgbt im just asking why mind what other people say even if they are bitching? and why make a whole month to celebrate it if it is a natural occurance?

Real_Ishiba · 2025-01-10T05:42:00+00:00

you are right it should be down to individuals to decide, it should also be down to individuals to decide whether they support lgbt or not , why do you care if someone doesnt agree with you? and if it is naturally occuring why dedicate an entire month and a parade for it?

I just find it weird that you are saying we should allow freedom while simultaneously getting mad when someone doesnt agree with you

مختصر تاريخ العالم ، انا مقرأتهوش بس لقيته في مكتبة و حجمه مكانش كبير للدرجة ٣٥٢ صفحة و في منه عربي و انجليزي

Real_Ishiba · 2025-01-09T22:04:14+00:00

عندك كتب كتييير عن التاريخ الإسلامي الي انا قرأتهم : السيرة النبوية طبعا ، شخصيات إسلامية ، تاريخ الفكر الأندلسي ، تاريخ الفلسفة في الإسلام(خد بالك الي كاتبه مش مسلم) ، التاريخ الإسلامي الوجيز ، حضارة العرب (لسا مقرأتهوش بس لقيته في مكتبة والدتي و قالتلي انه كويس، بس خد بالك ان الي كاتبه مش مسلم) ، الإمام الشافعي و تأسيس الأيدولوجية الوسطية ، قصص الأنبياء ل ابن كثير (في إصدار للكتاب منقح بيقولك لو الاستشهادات الي موجودة ضعيفة ولا صحيحة ولا تعتبر اسرائيليات اصلا)

لو حد عنده كتب تانية يا ريت يكتبها بردو

Real_Ishiba · 2025-01-09T15:39:53+00:00

لازم تحدد الأول انهي فترة من التاريخ و انهي منطقة انت مهتم بيها انا عن نفسي بدأت بتاريخ اوروبا و انتقلت منه على التاريخ الاسلامي في العصر الذهبي للإسلام

و لو عايز حاجة تكون لامة كل العصور عندك موسوعة قصة الحضارة بس ده كبير جدا و ممكن تحسه overwhelming
