    Are Deoxit contact cleaners worth the money?

    Butter doesn't work as a replacement. I trusted deox for 3 years, then they took out all the pcb's and acids, and I couldn't get it to work anymore.

    What transistor is this?

    burning generally means power circuit. I have never seen a signal component fry. If it is a voltage Regulator/Rectifier.. you said there are 3 on the board? Well was it made in Japan? The Japanese have used diode packs for years on their motorcycles. They found a way to control the serial...

    Capacitor charging circuit

    I think jets is right... I had once theorized I could fire a solenoid with a cap discharge but it didn't work because everything just dumped to ground... since then I have thought of a capacitor as a solenoid, and it's been working fairly well!!! After thinking about it, put a battery in there...

    Landline (VOIP) Caller ID

    FTTH is "fiber to the home": its a LL with optical couplers, not a VOIP, which is "voice over internet protocol" they are two completely different things. Personally, I like satellite, they have a requirement that says they can't bullshit you for a specific amount of time, and they limit...

    refraining from off topics in the lounge.... "What are the chances"...

    If a multi-layered device has a missing component,:confused: and you are capable of understanding the entire device and what it does, what are the chances of finding out what the device does, and bypassing or manufacturing something that will work? :oops: My smart kegger fridge of course is...

    I would like to repair my fridge-freezer. But what's wrong?

    Samsung said the reason fridges ice up is because the thermostat on the evaporator is bogus. Replace it immediately!~

    Fridge compressor test....

    thanks... The pump is a motor, you test the terminals for continuity, all good - motors good. but these are pressure sensitive devices, and I would think there should be some kind of pressure switch in there....

    Why do they use a voltage divider in this instance?

    The new LED's are probably the most inconsistent and untrustworthy peice of electronics junk that has ever been built. Most guys I know use them as regular diodes so they know if one burns out or not... The problem with them is they require a special power. It must be a certain amount of volts...

    Stainless Electric Motor shaft holder clip.

    When they bult these motors they couldn't get them to work... they finally decided that the power was traveling up the shaft of the commutator and filtering through the felt washers to ground it out. Wow they thought after deciding that a terminator should go in there... What should we use...

    Stainless Electric Motor shaft holder clip.

    I got another fridge that has a good compressor!!!(I know I can hear you all cheering now) but the compressor fan motor was stuck so I pulled it out and took it apart to free it up. It was not too hard, a hit it with my hammer in the right place only ten times before it popped open like a...

    Comedy Thread

    In music there is a phrase that must include all of the scales, most of the chromatic runs, part of the subquavers and be in its entirety, a single note that is not invasive to other instruments, does not bother the person beside you and offers the audience a break from the musical monotony...

    Who Here is into Arduino & Raspberry Pi. Are You Also Serious About Electronics?

    I am the independent researcher. The mux of the sitrep is like this. All devices are designed to do a certain job. That means that each is its own functioning part. When you try to eat an apple with the core, you have to remember that some appleseeds have more cyanide in them than others...

    ESP8266 for controlling selenoid door lock

    Your relay is way too big. Your node will probably have only 1 or 2 pins that actually work with remote wireless triggers. I've never studied this but I think that a node cannot work alone, it needs to be in a circuit that has the proper initiates, and a set of network params in the coding...
