    looking for a timing relay to use

    Check into TDR's (Time Delay Relay). They make delay-on, delay-off, all kinds of timing intervals, you just need to find what you want.

    Hello from China

    Yeah, I never cared much for the tags, especially since we've got enough gov't entities who are supposed to be doing security stuff. Germany was the fatherland, Russia is the motherland, and now we're supposed to be the homeland. (Especially considering the twit that's supposedly 'in charge' of...

    Hi there

    Studying electronics, I hope.

    Question about wiring DC input into boombox

    I'm in agreement with john monks. Your car battery gives very clean DC voltage, but if it's wired to the alternator, you'll see occasional (small) voltage fluctuations. I'd pick off the voltage after your car's voltage regulator (then you wouldn't need a separate rectifier), and make absolutely...

    Inductor core loss not calculable?

    Contact Coilcraft and ask them about your application. They've got some pretty sharp engineers there who know their products. Everytime I've asked them something about one of their devices, they've got very exact very specific information about their product. I'm kind of surprised the...

    Electron Tubes

    Look in the phone book for the closest Amateur Radio club, they'll want them a lot more than the waster recycler (and they'll use 'em for what they were built for).

    Who is this manufacturer? Data sheet?

    Three votes for Thomson-CSF. I'd try to get the spec sheet from them.

    Solderable paint?

    I liked Electrobrains idea, I suppose it depends on your final application. I will note, that they don't just make conductive silver in a nail-polish like base (used for circuitboard trace repair). The also make a nickel and a copper version. Check GC Electronics products. Silver stuff is...

    Best type(s) of capacitor

    Audio circuits are ok with electrolytics, which are generally cheaper. Electrolytics are for lower frequencies, most other makes are made for higher frequencies. Not familiar with the details about thermistors, I'd have to look them up like you are. 'tempco' probably refers to the temperature...

    Kenmore microwave magnetron

    Or, is there a schematic glued to the inside chassis of the microwave. Sears is usually pretty good about that.

    Need some help to ID what this component is

    The only thing I've found that can leak all over the board are batteries. It's possible the 'leakage' is something left-over from the manufacturing process when they built the board. Fluxes and solvents can sometime be trapped under the device (especially box-like devices), and then not be...

    Political argument (Yeah, this is going to end well)

    Thank goodness nobody but us, saw how politically incorrect we were when the mortar rounds were incoming.

    How to install a patch point?

    I don't know your application. If you're using the phono jack just like any device that ouputs to a speaker or a headphone type jack, they're designed for that purpose. (To work only the speaker or the headphone when you plug in the phono plug). Is your question about how to wire-up the...

    Amplifier repair

    Harald's right, either your load has a short in the wiring, or there was other damage to the amp when your transistor shorted. I'd check the cable (Ohm it out to check it). If it looks ok, trace the circuit that feeds the transistor, to see if something else in the transistor circuit was damaged.

    Political argument (Yeah, this is going to end well)

    GonzoEngineer & CDRIVE, I DID go into the VFW when I got back. It was just like GonzoEngineer said. All I heard was the media hype (FROM THE VETS THEMSELVES), about how drugged-up, screwed-up, and generally useless the guys like me were, who were coming back. Not only didn't I join, I've never...

    Political argument (Yeah, this is going to end well)

    That was a war? I thought it was a 'protective reaction strike'. I don't remember anybody declaring it a war.

    Salvaging from old equipment

    I think it's generally agreed, that sooner or later, if you want to save the parts, they'll need to be desoldered. It's not all that scary a thing to do. If you insist, I suppose you could hacksaw the board, but you might damage some of the parts you're trying to save. If you're thinking to cut...

    Hello from China

    We need more Austrailians monitoring 'homeland security' for the U.S.

    Salvaging from old equipment

    You'd need to want to learn to desolder without damaging the components. It's pretty routinely done, you just have to want to do it.

    Political argument (Yeah, this is going to end well)

    That started with SEATO, anybody remember that? You know, the 'NATO' of the Pacific. What started as an idea with Kennedy, got misjudged by Johnson. Ever read General Giap's memoirs? The U.S. somehow decided to honor their commitments to the region buy involving troops. When things got...
