    New here, need to find a momentary keyswitch

    Google the keyswitch, and then narrow the search for the operation you want. Of course the switch you needs exists. When you've identified a few of the manufacturers, email them to ask, if you don't see the switch you want on their website inventory. Get aggressive in your search, and...

    Anyone know what this is?

    The first thing I'd do is clean-out all that green corrosion from the contact spade-lug connector socket, and make sure the corrosion at the diode connection didn't eat into the circuit, causing a weak connection. Like *steve*, I'd check the diode, but wouldn't suspect it. You won't want to...

    Portable small smoke machine

    Well, I hope somebody here has a practical experience idea you can use for this. A switch is a switch. The one on your e-cigarette just happens to be a push-button switch. If you know somebody that dabbles in electronics, they may be able to help with this. There are a wide variety of remote...

    Sony TA-AX235 Protection

    This may not help, but some of those contact cleaners, especially when blown into pots, won't dry in an hour. Some also melt some types of plastics. Something may have been damaged when you powered it back up. Did you use the contact cleaner on switches or other components not previously...

    What do I have?

    If you can't use 'em, put 'em on ebay. Somebody can use them.

    low tech, high minded, outspoken... (by most...`,~) )

    Asking questions here, can save you a lot of time and frustration when you're first getting into electronics.

    Portable small smoke machine

    The first thing I'd do is check into the chemical they sell for electronic 'fogging' for special effects. Maybe you can use that in your e-cigarette itself, and figure-out a small propellent device to spread (or fan) the 'smoke'. These 'fogging' machines are pretty prevelant in the U.S...

    Oven broiler igniter

    We do need a picture if you can supply it. It's possible the ignitier 'connector' isn't a connector at all. Most of the igniters I've seen are molded directly to the wiring. You replace the igniter assembly with the wires. We'd need a picture to identify if you do have an actual connector...

    Capacitor Question - Repairing Circuit Board

    How many leads does this component have? The 1ufd 250V X2 has me wondering if this is two capacitors in a single package.

    can anyone tell me what part is this???

    Yeah, duke37 probably got them right. Maybe the teacher was being fancy with the squiggles. Google 'electronic component symbols', there are plenty of sites that give you schematic symbols. If you've got a printer, make a copy so you'll be ahead of the teacher's next example.

    Grounding question

    I'd get into all the circuits and find-out how they're wired for ground. I don't know a thing about car computers, maybe you can't get into those. I'd worry about floating the grounds, and having enough of a potential difference between circuits large enough to cause damage (because of...

    Component P 030 250

    I can't tell if the symbol on the top of the device is a company logo or a voltage suppressor symbol (back to back diodes). Can you get a better shot of the characters on the device?

    Valve actuator project

    Check into timer boxes themselves, not just for re-sale by pool companies, who mark-up the price. Maybe they're mostly fancy LCD read-out anymore, but I've been using the old electrically operated geared-clock timers for years with no problems. A motor drives a geared wheel with mechanical...

    2 X 4-20mA signals????

    Sounds like you want a 'summer'. Check Wilkenson Instruments, Red Lion, other mfgrs that make them for 4-20ma devices. You get a lot of information from reading the specs on their devices, and often-times you can contact technical support on-line to ask specific questions about what you...

    Motorola Transistor Part Numbers?

    Got me a couple bags of Motorola Transistors, TO-3 Package. Does anybody know what the cross is for the part numbers marked on them? 12901 and 3201123 (Two different types) thanks

    LM317T and how it works

    I don't know what you know about electronic circuits, but I'm wondering if you know that a LM317 is and ADJUSTABLE voltage regulator, as opposed to say an LM340T-5 (5 volt fixed), or LM340T-12 (12 volt fixed). You set the LM317 to the voltage you want with resistor add-ons. From your post...

    Simple Counter Help

    ha, ha, .... To electronics people like us, a 'counter', is a specific device for ascertaining frequency. Like Harald noticed, you want a circuit that adds-up different numerical values with the depression of each switch for each value. So we now know what kind of a 'counter' you were...

    What's this connector?

    The distance between the pins is usually called the 'pitch' by manufacturers, although the diameter of the pins (and if they're square or round), are also a factor.

    Please help me repair shorted out TV power supply

    What you want to do is what people on this site like to see. Somebody who wants to do things themselves, and are willing to work at it. The DMM is needed to make simple electical checks, you need one of those for almost any repair. You'll get plenty of people trying to help you with this...
