  • A viewer called Chris asked if I wanted take a look at these three faulty smart plugs. They look in really good condition, weren't used to switch heavy loads and all three just failed.
    Let's take them apart, see if we can find the problem and hopefully repair them!

    How often caps cause failure! I just replaced the starting capacitor on my 25 year old espresso grinder. Thanks for your videos. I am incapacitated and usually have to watch your videos on my cell phone. Due to a strong tremor in my hands I cannot comment on the phone, but I want you to know that your videos make my limited life experiences at age 80+ much more bearable, all the more because my favourite English dialect is Geordie!

    • @BuyitFixit
      @BuyitFixit  Před 23 dny +1

      I guess it depends on the make, as I did a little research on ESR and came across a thread in eevblog saying it's like asking what the weight of a cow should be. Depends on the make, electrolyte, etc so I'm still not sure how good of an indicator it is. Some people even posted pictures of bad caps with a good ESR reading so I think it's if in doubt replace anyway.

      As are so many devices these days - just use at least one cheaply made part in the manufacturing process and bob's your uncle.

    • @BuyitFixit

      Although on the last one, I think the original cap might have been OK, and it was the shorted SMD that was the root cause of that one.

    Wrt the Wifi boards, maybe take a look at Openbeken and Esphome. Most of those boards can be flashed to open source firmwares and you get rid of these CN cloud apps. Then the plugs also integrate better with home assistant etc. May be a video topic.

    Low value electrolytic capacitors typically have higher esr, up to about the 3-4 ohm is fairly normal for 1 - 4.7 uF.

    • @BuyitFixit
      @BuyitFixit  Před 17 dny

      Thanks for that. Apparently voltage of the cap plays into this also. I did find a whole thread on the EEVBLOG forum talking about ESR and how it can also vary wildly between good quality bad quality and different manufacturers and even bad capacitors can have a good ESR reading.

    • @jumboegg5845
      @jumboegg5845 Před 17 dny +1

      @@BuyitFixit Yeah it varies, the esr meter just gives you a ball park figure, its not a precision measurement, just gives you a good indication (so long as the cap is not shorted). Often works well testing electrolytic caps in circuit, its the ones that have a bit high esr, that's when you are unsure. A big cap with a few ohms or more, is not good, but after measuring lots of small caps in circuit, I find they often have a few ohms when perfectly fine.

  • @MrDubje
    @MrDubje Před 20 dny +1

    It's pretty much cause and effect what you're seeing here. The electrolytic cap probably failed in the last one, leaving the spikey high-freq rectified voltage to be smoothed by the little ceramic cap, resulting in its demise as well. Ceramic caps tend to fail in a short or become a resistor of varying value when exposed to voltage higher than their spec. Last month I was able to repair a display module in a Wacom drawing screen where the same issue occurred as a result of a suspected power supply problem.

    Love watching you save stuff from landfill. These didn't look old enough to have failed electrolytics - I was surprised. Bad product design in that they should have thought that if someone opens them (or even if the welds fail) then building in some mechanical clips keeping the front cover on would be good for safety. I'm sure it could have been engineered at no actual cost other than mould complexity. Keep up the great work!

    Electrolytics on plug top devices are quite common
    The datasheet for the voltage regulator on the unit with the shorted ceramic would most likely give you the value for the faulty ceramic.
    The leads on the component tester I bought one of the long legged turned pin IC sockets RS 188-2695 and soldered my leads to it, this way I have easy contact points for short leaded components or the clips like you have.

    Capacitor value on secondary not too critical, it just has to have a low ESR, and be able to hold charge so the relay does not drop out between mains cycles. The buck converters are very tolerant on value, just do not like to have too much ripple on input, and ESR has to be low, as they draw very short high current pulses, so high ESR means it drops into undervoltage lock out range during every mains cycle.
    Shorted capacitor likely just because it got spikes applied, or it was damaged during assembly, normally the 3V3 regulator goes short circuit in this use from the spikes as the capacitors age. Value of capacitor not critical, it would run without it as well, short lead lengths to main capacitor allowing it to decouple properly.

    Just a thought, but wouldn't ESR be "higher" if you're measuring with cables and those clips? ESR stand for Equivalent Series Resistance, so I'd imagine the cables and clips add to the measured values. You could try putting a cap straight into the connector and then measure the same cap with the wires, then see if you get different readings.

    • @BuyitFixit

    • @eostrike
      @eostrike Před 25 dny

      ​@@BuyitFixitthis tester tests electrolytic capacitors very well. It will tell you if it needs to be replaced, there is no guessing if the ESR is acceptable or not. I never take that $5.00 tester out anymore for electrolytic capacitors. Its expensive when compared to that lesser price tool but if testing electrolytic capacitors often I feel it is an investment well made.

    • @eostrike
      @eostrike Před 25 dny

      ​@@BuyitFixitone more thing to note. If you knew which cap to replace you would have saved money not replacing all the others. If the plan was to replace them all anyhow then the tester will not benefit you. If the goal was to show the audience which cap was the culprit and replace only what needs to be replaced then I recommend this tool.

    You never comment on the loss measurement of the caps. It's not a very standardized measurement but if it's increased there is a parasitic train across the cap.
    This very quickly leads to high loads on the supply-system. Often causing startup failure of switchmode supplys that detect the high drain as a fault.
