    Wiring sliding/linear potentiometer

    There is only three possible connections, do you have a meter? If so power the unit and check for the highest voltage across any two, the positive will be one extreme end of the Pot, the negative or common is the other end, one connection should most likely be something in between the two higher...

    16 Volt DC conversion to 12 Volt AC

    There are a number of IC for producing 60hz etc, one is the ELM440, it uses a very common 3.8mhz colour TV The output can be simply amplified if necessary. Google elm440 and also AC generating IC. crystal . M.

    Wiring sliding/linear potentiometer

    The terms Live, Neutral, Earth are only used in AC power supply or systems. With a 3 terminal Pot they connections are usually +ve, Common and the centre as Slider. M.

    How do I adjust the Voltage for an immersion heater?

    You could either make a suitable duty Triac controller (cheapest) , or there is high current dimmer style ones made for power tools that can be purchased. If you Google AC triac control, it should bring up alot of posts. Only half dozen components needed, DigiKey is a good source of parts. M.

    fluorescent ballast replace question

    If this is a standard fluorescent fixture and not and older style with a start switch or a mag lamp etc with electronics, there is not much else apart from the ballast and a bad contact on the lamp pins. More info on the fixture needed. M.

    Can we use 5VDC LED in the AC line to show indication

    As per post#2 use a neon, this is how it is done in industrial fuse holders to indicate blown fuse. M.

    12V relay with 9v battery_not working

    Do you have a 6v relay? if so you could use a couple of rectifiers in series with the coil. Relays have what is known as a fairly large hysteresis a DC relay once it is pulled in will stay retained with much lower voltage, but first you need to energize it closed.which as higher than the minimum...

    I don't see the average 13a plug fuse being fast-blo type? Not from my experience. It would cheap and easy to rig up and try before going ahead with a enclosed version. M.

    Burned a solenoid with a relay timer, and I don't know why

    Have you actually measured the solenoid coil resistance to find the actual current? M.

    You could either build or otherwise obtain a power triac (dimmer style) switch and run it ~50%. Another option that may work for you is obtain a single power diode (half wave) and place this in series with the kettle, you would have to construct it in a suitable enclosure or box, although a...

    I need a really small, really smooooth motor...

    You may be referring to the likes of DC motor armatures of high end and servo style motors, where the lamination slots are skewed, in this way the armature coils are wound at an angle WRT the field. Making for smoother rotation, most high end motors are wound this way. M..

    Light dimmer Capacitor help??

    If not the fuse then I would opt for the Triac will be toast. You can easily test it by meter if you remove it. M.

    I need a really small, really smooooth motor...

    Older style record players used synchronous motors, they are sync'ed to AC frequency and keep very accurate rpm control, reduction is by synthetic rubber wheel. This is why if taken to a country where the frequency varies the reduction wheel has to be changed. Any of the modern BLDC motors...
