    Canon VIXIA HF S10 A read data from inernal flash memory.
    by abajor
    Hello I've had somebody bring in one of these charming little cameras to attempt retrieving data from the internal 32GB flash.
    Something is damaged inside the cameras lens assembly I can hear it clunking around and it has probably dislodged the sensor, powering up the camera gives a blank screen and the focus motor sounds like it's having a fit.
    The camera will not connect to a computer via USB in this state, I have no options no navigation, just power up and focus/zoom motor noises.

    I think my best shot is to figure out a way to read the internal flash memory outside...

    Hi

    x1 Carbon Gen 9 HYG60\HX4B0 NM-D341 Rev: 1.0, CSD87501L Failed solder Joints.
    by abajor
    I had a x1 Carbon Gen 9 come in with a no charge and no USB C power up problem (the machine would turn on with a new battery until it lost charge).
    I noticed lifting the protective black membrane near the USB jacks that two little BGA chips were stuck to the adhesive and had fully released from the mother board, one of them looking fully scorched. Q261 and Q263 power MOSFETS.

    I found the schematic and diagram for the board here.

    Advice sought - Selector switch knob repair
    by ClockChip
    Hello Everyone,

    I am seeking to repair a knob on an old (circa 1971) Panasonic clock radio (a model RC-6900). The good news is that I have the small, easily lost knob. The bad news is that the knob has come off a slotted post and I need to re-attach it in such a way that I won't have to worry about it coming loose again.

    Here is a picture of the bare slotted post (if I have the term right) the knob should be attached to:

    Modification to a ZD-987 desoldering/soldering station using a external switching power supply
    by sam_sam_sam
    I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

    I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

    Toshiba Satellite Radius 14 Bios extraction help
    by rddube
    Hello,

    I am trying to extract the Bios for this machine (I bought this on Craiglists and it is a Toshiba Satellite Radius 14 with no serial number and the Bios chip is blank!). Attached is the file and I followed the instructions SMDflea suggested, but when I run this, it doesn't create a .com file it creates a .rom file?

    Please help and thank you!...

    Can someon Help me, I have a GH51M LA-K862P, and there is a short somewhere after PRB3 and PRB46. I've looked for it using a thermal camera, but I can't find it. Maybe we can find it together. It's a very interesting case.

    i was trying to find the issue when i noticed this part does not fit snug around the tip going to the top
    my nozzle has a diameter of 0.1" and my rubber part linked below has a diameter of 0.155"

    Am i missing a part or has the rubber melted?https://I have a ZD-915 de-soldering...ere is no clog

    i bricked my bios using the smokeless umaf tool and trying to tighten ram timings. i purchased a ch341a programmer and made the mistake of not backing up my bios before flashing the stock bios on the chip. i tried injecting my serial and all in the bios and then flashing but now the hdd light just blinks when powering on and nothing else. ill attach the firmware i flashed to the chip and the default i added it to. also the chip is a winbond W74M25JWEIQ. my serial is N2NRKD019645059...

    by iMuhtaseb
    This computer had an SSD failure initially and I've replaced all NANDs with known-goods and made huge stress tests on the SSDs and on the computer.. then I sold it..

    Now after two months of selling the laptop it retuned on 5v and drawing 0.200 amps.. T2 is heating up and U6960..

    T2 PMU has all voltage power outputs also U6960 is producing PP3v3_G3H normally..

    All USB-C doing the same behavior no USB-C port behaving differently all taking 5v 0.200 amps..

    I took measurements for shorts all around and found nothing..

    Board is not in...

    Raspberry Pi 4, probable short onboard
    by kaput
    A few days ago, I smelled magical smoke, but couldn't pinpoint the source. Now when trying to 3D print something, Octoprint wouldn't respond, and I soon found that the stepdown powering the RPi 4 running Octoprint had burned out. Assuming that was where the smell came from.

    No idea if the stepdown failed and took the Pi with it, or if the Pi failed and took the stepdown with it.

    Measuring resistance between ground and the 5V line on the Pi, I get 0.2 ohms, more or less a full short.

    There's no visible damage to the RPi, checked the circuitry around the power...

    Hi all, due to a mistake a friend connected a wrong USB pin to the laptop. The laptop immediately stopped running and never get back to normal functioning.
    If I connect to the power supply the only sign that I have is three blink forn the power button and in accordance with user manual this only means that a power supply has been connected. With battery no signs at all. My understanding is some hw problem to the mb. The laptop is an old one but still working so I wonder if it is worth to repair or buy a new mb for 25/30 USD. Does anybody have suggestions what to to or check before throwing...
