    Idiot with coffee fetish

    ^ Depends on the design, generally the gearbox has screws on the inside wall going into the end of the motor casing and those motor casing tapped holes can be used with same or longer screws to mount the motor elsewhere. For example that can be seen on the following diagram as two screws (a...

    Car ECU think I found the fault?

    My initial suspicion is that you're going about this the wrong way, or at least have not mentioned troubleshooting up to this point. The ECM is not usually the culprit for a problem that occurs once an engine reaches full operating temperature. First what is this "fault" when it gets to...

    Idiot with coffee fetish

    The motor could just be used with the drill's gearbox, but the motor is the easy part. By the time you buy parts and fabricate the grinder portion, you might as well have just bought a ready made grinder. These things do exist, so seems like a case of reinventing the wheel, except at great...

    How do I reduce the speed of a 12v childrens car

    I see a silver blob with a label. You desperately need a better camera and to provide better pics. If we could have read the label we might have been able to figure out how the controller works.

    Thoughts on Engineer PA-09 Crimp Tool?

    I'd go ahead and get that considering the price difference, then return it if it doesn't work well.

    What's this part please

    I too vote capacitor. This PSU has a fault and you're at the point of pulling components to troubleshoot?

    How do I reduce the speed of a 12v childrens car

    Won't the throttle be going to a potentiometer or some other variant of a variable resistor? If so I would measure its resistance at the various pedal positions and use a switch to switch an added resistor in and out of the circuit to limit the sensed throttle position. You hide the switch so...

    Nail Polish Remover PCB

    It's the acetone in nail polish remover that gets the toner off. Yes you can use nail polish remover but a jug of acetone from a hardware store is much cheaper per oz and stronger so you need fewer ounces per job... and doesn't leave all those other ingredients behind that you need a 2nd step...

    Seems like a little more info could be useful.

    Cooling soldering iron quickly after use to reduce oxidation

    I mostly use Hakko 936 compatible iron core tips, sometimes the generic versions of them, and turn down my temp controlled station to its minimum setting if I won't be soldering anything more within the next dozen seconds or so. Granted it has a reasonably good temperature recovery time...

    Focal XS 2.1 sub woofer, sealant

    Looks like just cheap general purpose construction grade adhesive. It is unimportant that you replicate that, could buy construction adhesive from a hardware store, or you could get latex/acrylic or silicone caulking, but generally speaking the typical construction grade silicone is acidic and...

    Beeping from disconnected system

    Your smoke alarm detected a fire in the next room. Get up and put it out. Or don't. ;)

    Soldering through parylene

    Their website states it has poor resistance to abrasion. Scrape it off the repair area the best you can. I'd try with an X-acto knife blade (depending on what it is). If you have a temperature controlled soldering station then you could also test the burn off temperature in an unimportant...

    Resistor Question

    That resistor doesn't look bad to me, are you sure it is the resistor itself rather than a bad solder joint or broken trace to it? No at that level it is just a current limiting resistor and you can pick any with similar specs, though if it was running hot and you can fit a 3W in its place...

    Repair electric kettle (Klarstein) - broken power switch

    (continued because my ISP crapped out for a while) Granted, there was minimal info provided. If this makeshift switch they integrated, latches on until a certain temperature and then permanently disengages, a thermal switch alone will not replace that. I also skipped a few details. For...

    Stabilizer for fridge, washing machine and Led TV

    Depending on the size and age of the refrigerator and washing machine, if they are on the same circuit then one starting up while the other is running may be enough to kick the breaker. Since you have little control over when the refrigerator cycles on, the solution is to not have them both...

    Repair electric kettle (Klarstein) - broken power switch

    ^ I have repaired many, many things over the years. None have burst into flame or done any harm. A switch and a thermal cutoff are $2. If the product costs $30 then 1/15th of that to repair it seems reasonable, and eliminates the manufacturing materials, expense, and pollution of making a...

    Repair electric kettle (Klarstein) - broken power switch

    ^ In that case wire a thermal cutoff switch in series with the new switch. Measure the temperature of the heating element to select the right temperature value and mount it to the heating element. Then again, it might already have one.

    Draw air from enclosure or push it in?

    You should orient it the same as the original fan. In some cases this doesn't matter. In other cases it does, particularly if the fan isn't just meant to exchange out the heated chassis air but also to blow directly in on something near it. If you provide a good picture of the inside of the...

    Smoothing output of a full bridge

    By being after the bridge rectifier the polarized capacitor is already in series after a diode (two actually), so adding another would be a redundant loss of another ~ 0.7V for no reason.
