    +15V supply shorted

    I'd be looking at the circuit further down the line that the +15 feeds. Is it drawing too much power, or maybe a short in the circuitry there?

    My sony handycam CCR-TR5 will playback video but wont record

    Too many things can go wrong if you try to repair this yourself. I check Sony authorized repair places for all of my camera gear from them. If the price is too high for repair, I get a new camera, .... they're starting to become throw-aways now anyway. If you can't find a authorized repair shop...

    Mathematics

    I HATED math in school. I LOVED working with electronics. I LEARNED that electronics is just practical application of mathematics.

    Short/open circuit detector in wall

    I think it would help if you explained exactly what you mean. As noted in previous posts, is this for audio signals, power wiring, or something else. I'm curious about the 'open or short circuit in a wall' question. What kind of application are you talking about?

    Electrical Conductivity in Tap Water

    I'm guessing this is a theoretical question for school? (where a constant is given?) My practical application experience is that depending on the application, we TEST for conductivity because the volume of suspended contaminants matters. Sometimes conductivity is read between two probes, but...

    Broken Y terminal on furnace circuit board

    You don't sound like you have electronic/electric repair experience. A hot glue gun fix is not a good solution. Minder's idea of just using a screw extractor to remove the headless screw is a good quick fix. Any simple mechanical experience? Ace Hardware could tell you what you need to do...

    1/4 inch mono jack 3 pins

    If anybody's taking a vote, here's my vote: If you're SURE it's not a STEREO jack as offered by BobK, (I assume you know Mono (2-lead) vs Stereo (3-lead). I'd tend to believe Harald Kapp's theory of a switched jack. Designed to send the audio signal to an amplifier, but when you plug in the...

    Pioneer radio wire harness questions

    In case you don't know, wire harness kits are widely available for what you did. (Remove a Pioneer radio from your old car and install it in your new Chevy) They can be purchased on-line, or from a car radio install shop. You tell 'em your vehicle and radio make, and for $10 or $15, you've got...

    Laser toner refills

    Yeah. The model may be important. Some of the toner manufacturers put chips in the cartridges to identify their products, and when they read 'empty'. Savvy refillers over-ride the signal when they refill the cartridges. I don't remember hearing of any particular problems with the vast majority...

    Electric Mower repair

    73's de Edd is one of the best failure analysis people I've seen on this site. He's probably got troubleshooting information that will help you out. I think you're probably right about water causing your problem. My input, is that the last two electric mowers I've fixed, the switch itself has...

    Security for Newer Vending Machines

    Vending machine manufacturers specifically design their equipment to prevent field losses of their products (and cash input). If you're trying to defeat the vending machines in your freshman dorm, buddy-up to one of the rich kids, and have him (or her) subsidize your munchies. Most of the...

    Display instability for temperatore sensor

    What timff is describing is what is called in the industry a 'thermal well'. Basically a covering for the temperature sensor you're using itself. In industry it's used to isolate the actual temperature element from direct exposure to any physical contact with whatever it is you're trying to...

    Banana Test Connector

    Yep, lots of manufacturers for that type of connector. You'll have your choice in lead wrap-around like the one you pictured, or lead insert into the base, screw insert lock-down, and others. My advice is to look at what's available and choose what best suits your needs. I will also mention...

    Anything you wish you knew/glad you knew at the start of your education and/or jobs?

    I begrudgingly had to take classes I had absolutely no interest in. The schools would offer classes with a clause if the class filled-up before you could get it of : 'what do you want as a secondary choice if you don't get your first choice'. I begrudgingly now admit that every one of those...

    Sharp vcr a-50 player wont play tape

    I'd try a tape head cleaning tape, although kellys-eye is probably right that it could be something else that would be expensive to have fixed. If the heads inside, that the tape runs across are coated with material debris from previous tapes being run over them, sometimes that causes the tape...

    Display instability for temperatore sensor

    Good ideas posted above. Here's one more to consider, a sample and hold circuit that clears itself every 3-5 seconds. The problem I have with trying to figure-out what to do, is that I don't know your application or specifications. +/- .1 or .2 degree fluctuation (depending on the accuracy of...

    Did you try contacting the manufacturer for specific information on this product?

    ID 8-pin DIP

    I'm thinking along davenn's line of thought. It'd be hard for me to believe a melted 8-pin DIP is your only circuit problem here. Something, somewhere, CAUSED that DIP to melt. Without a schematic of the circuit, a new board (and if not, a new humidifier) might be in order here.
