    Wedge under the cabinet leg.

    Why not level up the cabinet - blocks under the feet .. ?

    Two reasons why not; there are two of them sitting next to each other. And the material is mdf which is prone to sag and flat at the bottom so using wedges it would give a gap at the left side at the bottom.

     

    I'm now using small peggies, on points where the pressures are high, and lift the cabinet 0.5cm from the floor to avoid water going into the wood.

     

    Having stuff on the cabinet the gap is barely seen now.

  2. We are living in a townhouse, in the whole street the ground in the back has sunk a little.

    Put a ball on the floor, and it will roll to the back. And so does fluids..

     

    Rough measurement gives 10 cm over a distance of 12 meters. Close to a sinking ship ????

     

    I did mount a whiteboard last week, which is 120cm wide. And when drilling the holes I used a level.

    Now I moved a cabinet under it, at the right side it fits nicely under the board and at the left there is a gap of 1 cm.

     

     

     

    Now what would you do when you hang up a TV, art or anything else on the wall.

    Level to your eyes or level to the gravity?

    A few years, why will that help fix it?

    Hard drives have a life span, so It gives a good indication of its condition. I believe the WD passport has a 3 year limited warranty.

    There are a few sorts of 'life spans' , the most important are the guaranteed hours of use (mileage) which is at least 100.000 hours of use.

    This is called MTBF, Mean Time Between Failure.

    I found that for consumer graded harddisk the 'age' , when used continuously, is one-third of the 100.000 which is around 3-5 years.

     

    Warranty is not a lifespan but you can say the company knows the MTBF and also use the one-third rule hence can 'promise' the 3 years warranty.

     

    Another life spans is the durability of the materials, which is much longer, 10 years at least.

     

    Then there is another 'lifespan' which writes them off after 3 years, even when they are still working fine. They get replaced to avoid errors. This is done with servers.

     

    I'm using harddisk which all exceeded the ''warranty life time''.  Some of them 10 years already.

    Few of them are type red (nas drives) , most of them blue (normal use) and no 'greenies'.

    These coloring are used with WD harddisks, other brands have naming for the purposes.

     

     

     


    For those who want to know what the coloring of WD harddisk means:

    WD Blue HDDs are mainly used for general purpose storage, they are great all-rounders, and an average user can’t go wrong with Blue.

    WD Green is basically same as Blue, but it lacks a bit of performance. However, it is the most eco-friendly HDD, and it’s quite cheap.

    WD Blacks are for pure performance including gaming, media, and content creation. Also one of the most expensive HDDs.

    WD Red is a NAS drive. It’s optimized for NAS systems.

    WD Purple is for surveillance. Advised for 24/7 operation.

    WD Gold, probably the most premium of all. Made for a multitude of Datacenter-specific applications.

    it does make some noise when first plugged in, but then stops.

    A long shot ... maybe your USB port 5V is not good .. problem with the USB computer power source to the drive ...  Try a different computer if you can .. Is it used with a laptop or desktop ?

    Also try another usb cable.

     

    I have a few WD passports here, and the cable of one of them failed after a while making me stressed as I used that harddisk as backup and was thinking the harddisk itself was dying on me.

    Same with another Samsung harddisk (mini usb era), changing with another usb cable and it's still there, the symptom with this one was the same as yours.

    Maybe. 

    Eg  if I with two Issan people together, for be polite, they will speak thai, not Issan. 

    Because I not speak Issan well, they speak thai. But if I not there, they will speak Issan. 

     

    When i with not south people, I try not use south dialect. Just for polite, consideration.

    Yinn have xenoglossophobia to learn Isan language? ????

     

    I speak English, it is not my first language.

    This Forum is English, good that you come here to improve your English.

    In Thailand I use both English and Thai, good more if Thai speak English.

    Not only for me to understand, but also for them to 'see' the world.

  6. The chemical products Heptane and Naphtha comes close to the 'Wasbenzine'.

    You can use it to clean fabrics with which then removes heavy grease stains.

    It's also used as thinner-solvent (It is not -Thinner- but it thins the paint)

     

    For household, (Dutch) wasbenzine is one substance and sold as one product in stores for the purpose to clean brushes and for degreasing purposes.

  7. When I saw it I compared it with 'Wasbenzine' (Dutch, no english wiki).

    'Wasbenzine' ; we used it for cleaning and degreasing, just like this Sophon White Alcohol promotes.

    Clears residues from stickers and tiree inner tubes as well.

    Not as strong as 'Terpentine' (White Spirit) and Thinners

     

    Quote

    Wasbenzine is a solvent consisting of saturated hydrocarbons with 5 to 15 carbon atoms of the formula CnH2n + 2, for example C7H16. It is used for degreasing and cleaning.

     

    What is the English equivalent version of 'Wasbenzine' ?

  8. Polls are available upon starting a new thread.

     

    For threads that has quiz/puzzles topics it would be great, if there isn't already, an option to post polls as comments.

     

    This could be the code.

     

    [poll]
    - Option A
    - Option B
    - Option C
    [/poll]

     

     

     

    Is there?

  9. This was indeed a 'tricky one'.

     

    The main feed would be at the right side, same side as where the connection clamp for the earth is too.

    The cable gland which is 'free' and bigger then the other is also on that side.

     

    Then I observed the cap wiring, the lid and the embossed wiring diagram made the conclusion that the mains wiring should be at the marked tabs.

     

    -And- I saw that the lid can only fixed in one position, as the height is not the same. Not squared but triangle/trapezoid.

     

    The picture of the motor itself is inverted , obvious as cable glands usually are on the "bottom side"  (quotation marks, as it's neither top or bottom in this situation but from the view of installer it is).

     

    And the picture of the 'Star' connection gave out the definite confirmation :whistling:

    This setup is a delta wired configuration with the cap acting as phase shifter.

     

    If the motor rotates in the wrong direction, then yep, the brown wire has to be moved to the 'marked tab' as in @Crossy's comment.

     

     

    Tip for the OP: When connecting the wires, make sure the wire for the earth is longer (even longer then needed to get to the clamp) so that when the cord is accidentally pulled the earth connection is disconnected as last and not before the other two (L + N)

    Or do you mean that blonde that crossed to Swansea roughly fifteen years ago?

    What is the question ?

    Watt is the answer 

     

    Yes I mean Watt, Steven Watt.

    2006 he moved to Swansea City.

    So I think you are right too.

    Yup, same total resistance in circuit.

     

    What's the load and the desired effect?

     

    It may be better to use X rated capacitors to reduce the power dissipation.

    Really a 'must' to use X2 rated capacitor opposite to other kinds of capacitors.

    It's a feed that gets beating 50 times in a second continuously and X caps are more suitable for such task.

    Failing caps are dead shorts and that would pass the 230 mains to the led, poof.

     

    Leds cost near to nothing.

     

    Thinking about using cap drops for the ESP boards, would be better with zener (5.6v) and fuse.

    Or 'bigger cap ' like the 225K and little transformer for 24v to... 5v.  Not sure yet. What would you do?

    Do you have capacitor 100n (marked 104) on hand?  Use that in series with one resistor and the led, and the led in parallel with diode other way around.

    Do it like this:-

    Just what I had imagined ????

    You mean, do you have a 100n capacitor of suitable voltage rating and be careful of voltages left on capacitors after disconnection.

    No, I did not mean to say that so I didn't.

    It's common sense to use one of suitable voltage (it's more important that it's an X2 type) -and- we are talking about capacitve dropper, not a elco (dc) or ladder structure which holds strong charge.

    It would not always much, but yes it can, hold a charge.

     

    You can shunt it with a bleeding resistor of 1Mohm, which empties such a fully charged cap of 0.1u in 0.6 seconds.

     

    As indicator light connected in parallel it will eventually bleed out fast caused by the connected electronics at the mains side.

     

    Used just as one thing, only the led and nothing else, where you pull it from the mains then you need the shunted resistor for bleeding the cap.

    Eg 100n-400V in series with 500Ω inrush limit + diodes

    A capacitor in this setup (X2 , 100n) has 32Kohm resistance and a no-load voltage of around 4V and 8mA when put in series on the mains.

    Add the 500 Ohm (470Ohm) is good for using one led.

     

    Most leds are happy with 20mA and around 2 volt (Green 2.2 and red 1.8)

     

    I would use the three leds with a 1.2K in series each led, with  1uF cap which gives you no-load voltage of 24 volt and 40mA.
