    Power Supply safety device

    This has been something I've been wanting for a long while, a device powered by the ATX cables +5vSB that can monitor temperatures. (With included temperature diodes on nice long cables so you can stick them anywhere.)
    And also fan outputs with RPM monitoring, so that when the RPM/temp gets too a specific (user configurable) point the safety device will be triggered; which should simply consist of a relay that cuts power to the ATX connectors pin 14, PS-ON which will poweroff the computer immediately...

    It should also provide monitoring off the +5vSB line so that if it falls outside the ATX spec it too is turned off (to prevent the mainboard from being damaged because the cheap ass capacitors and other crap in the PSU has failed so the line is giving out 8v or 2.5v instead....)

    The fan outputs should also work while only having the RPM cable attached, i.e. not power cable. So you can still use the mainboards temperature/RPM control feature if it has it... (That is if you splice the fans cable into two connectors, one with only RPM sense and one with +12v and ground...)

    The fan outputs should also be built to be able to deliver allot of current, so if you wanted you could run a water pump from them (though most pumps now days have split voltage input/rpm sensor cables just as described above so it is less of an issue...)

    This isn't much to ask for right?

    Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
    by Tynan Dill
    I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

    Upon bringing it home and plugging it up, it showed a standby light.

    I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

    The screen seems to blackout and stay black, but with a flashlight I can see the display.

    With my Playstation 4 connected via HDMI, and running a game I can hear sound.

    Assuming...

    Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
    by sam_sam_sam
    I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

    One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

    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...

    Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
    by shamsudeen
    Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
    I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

    i know that in linear power supply the noise will be very low comparing to SMPS supply....

    Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
    by JimBanville
    The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
    Opened it up and discovered the power supply is making a faint clicking or ticking sound.
    I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
    I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...
