    Need a replacement power cord- dont want to burn down house

    The power requirement seems pretty standard. So is your specific question about what type of power connectors to use, or are you wondering if maybe you need a large-diameter wire in your power cable? Do you have a power cable input jack connector on the sound mixer, or are you saying there...

    Safe sequencing of power

    Maybe he was referring to Chinese kilowatts. (That was intended to be an (insensitive, maybe) joke

    Building charger cable help

    Yeah. We're at a loss without a picture or specific make/model information. Many manufacturers make connectors specifically for their wares. We don't know if you have a common, readily available one, or something that is manufacturer specific to something in particular.

    help 'tricking' a light sensor. What is this sensor? for car auto headlights

    Isn't modern technology great? Why don't you call the car dealer and ask them. When they sell to rental car places, they rig the cars so that the headlights stay on all the time. It probably isn't difficult, maybe even a command to the computer. If you keep hacking without knowing exactly...

    what am I

    davenn, if you've still got your own teeth, you're younger than me and hevans1944, and you HAVE seen a dino before. Just take a look at hevans1944's avatar. I don't use an avatar because it'd be even more scary. I am presently working in a metrology lab that services (among other things) new...

    Flyback joule

    Is it a standard incandescent bulb? Rated for what voltage? What's the wattage rating?

    Sansui SP-2500 Speaker Crossover Repair

    I lean toward dorke's suggestion. Buy a spray can of electronics contact cleaner from an electronic parts supply store and spray out the switch contacts while rotating them. This probably has nothing to do with your issue, but I'd check to make sure whatever you're using to drive the speakers...

    Flyback joule

    Did you check to see if you burned-out the filaments in those bubls?

    What to do with a smartphone charger with a broken pin?

    Like KJ6EAD said. If you've got room, save the guts in the event you stumble onto a similar dysfunctional unit. Make a spare good unit out of two defective ones.

    Reddish brown corrosive stuff

    Not illumination of the unspent phosphorous from the expended munition?

    What to do with a smartphone charger with a broken pin?

    My daughter had the same problem. The connectors are unique to the mfgr, yes, you gotta cut open the case to get at it (IF, you can find a replacement), and then it's a bear fitting everything back together and resealing the case. You can do it if you're a real do-it-yourselfer, but I just told...

    Reddish brown corrosive stuff

    My experience with a lot of the devices coming out of China is that the assemblers are in a hurry for piece-work. They just want to get the item done and tested, and out the door. To speed things up I've seen (maybe authorized, maybe just somebody just getting the job done), parts tacked in...

    voltage operated relay for automotive

    I'd go with Analogkid's advice. You can't practically rely on the relay itself for your application. When your battery gets older, you might inadvertently drop below your 12.8 voltage threshold for a short period during crank-up, and that would probably cause you unwanted problems with your...

    Free Energy / Energy Harvesters / Perpetual Motion

    Wow. It's sounds like there's all kinds of free energy out there. The sun, the wind, the water, geothermal, maybe even fire. Too bad it costs money to harness it for human use. I suspect that if somebody does figure-out how to actually make it 'free' for human use, the government would tax it...

    Multimeter

    Good work elebish. Thanks for not giving-up Jimmie. It's disappointing to hear other people throw in the towel without trying.

    Hello Everyone, Newbie here ! Need help repairing a amplifier.

    Usually the first thing to fail on these amps are the big electrolytic capacitors. When they leak (electronically), circuits start failing. My personal experience with single channel failures are the selector switches themselves. They get dirty or just plain wear out. First thing I check is to...

    CD Tray Won't Open

    And if all that fails, open the cabinet up and take a look at the mechanism. Maybe a plastic part broke.

    Multimeter

    You've got a open circuit in there somewhere. You just need to track it down. How do the traces look to your switching functions? Any damage on the printed circuit board trace? Varistors (if your meter has one) are used to absorb momentary voltage spikes. Typically if they fail they explode...

    Wire size for current?

    You're overhauling a tank. Tha fios agaibh is probably right that 14 gauge will work for your elevation, but why chance it and then have to go back and rewire it again later. A bunch of guys get funny and take rides on the barrel and your 20 amps is going way up. (The wire heats-up and the...
