    If I were you I'd just pull the plate off, stuff about 8sq inches of fiberglass insulation in the hole to fix the drafts and put the plate back on, or whatever kind of speaker terminals you want to use. You can buy decora plates with just about any type of outlet.

    Whirlpool oven heating very slowly

    Sounds like two separate problems; One with the thermostat circuit, and one with getting power to the element. The latter could be a number of things such as: Insufficient voltage at the power outlet, insufficient wire size wire to stove circuit causing a voltage drop under load. A bad...

    Whirlpool oven heating very slowly

    Good points Bluejets. I would also have the line voltage checked when the oven is heating up. If its low, the wattage will be less. There could be a problem with the thermostat bulb or its capillary tube. There's often a calibration screw on the thermostat that can be adjusted to match the...

    Home automation and question about Neutral generation

    Good point, although on this side of the pond, gfci breakers (for leakage) are usually not required for indoor lighting circuits.

    Home automation and question about Neutral generation

    The neutral is a current carrying conductor. The ground (equipment ground) wire is not. It is intended to carry current only in the event of a short circuit (ground fault). If you hook up any device that utilizes power and tie it to the ground wire, it causes parallel current paths which causes...

    Need Capacitors for RCA tv

    Those are just reference numbers. Post a picture and we'll help you find a replacement. The important numbers are in mf or uf, and its rating in volts, or V

    I hear you. Like I said, I don't think it's a big deal. It's worth noting that at this point it's not abandoned because it's presumably terminated at both ends. Just because you don't or rarely use your stereo doesn't render the wiring abandoned. Chopping them off and leaving them in the wall...

    Is there even a difference if i use a thyristor instead of a transistor? Also any improvements?

    I've no idea what loop you need nor what game your talking about. I don't think it'd matter much what type of wire as far as the circuit is concerned.

    It's not abandoned until you disconnect the terminations and leave the wires hanging in the wall. Not really that big of a deal, but the intent of the code is to prohibit people from leaving a mess of communication wiring in the walls which may interfere with power wiring and emit toxic fumes...

    No, its a decora blank cover. Here state side; abandoned class 2 and 3 wiring has to be removed according to the national electrical code.

    Is there even a difference if i use a thyristor instead of a transistor? Also any improvements?

    Yes, a thyristor will have different specs. There's a npn transistor here driving an led and buzzer. I'd start by describing the load you want to drive. Then figure out what components you need. Btw, that circuit doesn't show any current limiting resistors for the leds and transistor.

    I think your right. They are speaker terminal outlets likely used for surround sound. You could just cover them up with a blank decora cover plate, but the abandoned wiring should really be removed. especially if you remove the junction box.

    Failure on oven control board

    Even if board is melted beyond replacing the terminals, it may be possible to install a relay externally elsewhere in the oven. But I respect your decision to call this one a lost cause

    How To Prevent Short Circuit With A Simple Wire From One Outlet Prong To The Other

    It depends on the load you want to protect. Short circuit protection is already incorporated into your homes circuit breakers in the electrical panel. This usually limits current to 15 or 20 amps, but a supplemental fuse can also be added to your load (whatever is plugged in), that would limit...

    Failure on oven control board

    Sage advice to get a qualified repairman but with all these type posts, it's assumed the poster realizes he or she is working with dangerous currents but feels confident in doing the work themselves but are seeking guidance from the community. I've seen problems like this hundreds of times...

    Could you guys help identify some things?

    Olivia; You might consider selling some easy to ship items on eBay where the high bidder determines the price. Btw, I appreciate your dads service to his country.

    Failure on oven control board

    Looks like a terminal block insulator that melted. Likely that black relay behind it failed, causing it to overheat. If it was my oven, I'd cut and strip back a few inches of the burned wires and crimp or resolder directly to board after replacing relay and verifying element was ok. You can...

    What's wrong with circuit?

    Ok, but I was thinking the 4k7 was only for limiting current to the 33n. Examples of Rc filters seem to always have the cap in series followed by a resistor in parallel. Just using one stage 22n and 1k, I get 7.23khz. But don't know how the second cap in conjunction with the diode would be...

    What's wrong with circuit?

    Thank you bluejets. The video says its 18khz. I think the high pass filter is comprised of the two 22n caps and the 1k on the left side. I plan on having the transmitter triggered by a Pir motion sensor and will see if receiver portion works without any false trips. I don't want it going off...
