    Will this switch work with what I'm trying to do?

    I'll mention this in the hopes of helping you avoid problems later. There are a lot of audio/visual switch boxes available on the market, and they're relatively inexpensive. They're designed for this. What you need to be aware of, is that signals from several different sources can cause...

    Have you seen one of these and how can I make it work.

    Google the RCA Model number, and see if you can find a free on-line manual for it. It's not just a teaching aid, I use them regularly when repairing electronic circuits. Like AnalogKid said, if you're not sure exactly what component value you require (for example when a component burns-up in a...

    That guy sold 679 of those units so far. That's 2,716 loose noozles out there. Aye, we have been warned.

    help finding part "psi sensor"

    I'm curious about how you intend you use this. Are you expecting to have the sensor operate WHILE you're riding the bike? Or is this something you intend to attach while in storage between bike rides, to let you know you need air before you take the bike out for a spin? The reason I ask, is that...

    Help finding alternatives to this non-existent capacitor!

    I don't know, but here's my guesstimate in the cap width question. Capacitor manufacturers get orders from product companies for components that fit the boards their designers come up with. They'll make you whatever you want to get the contract order if the price is right. I too have often found...

    RTD Thermistor Fine Tuning circuit

    Get on the Omega website. If you don't see what you want, contact them for one of their engineers to help you. You don't want to reinvent the wheel here. The engineers at Temperature device manufacturers have heard and seen it all. They can help with specific rcommendations.

    Identifying a resistor

    Actually, the paint bands look to be in good shape, so I believe they're ok. That component package is a 1960's era type that was pretty popular. It was used for some resistors, inductors, and even some capacitors. I'm pressed for time right now, it's Friday; but I'm thinking with two silver...

    Identifying a resistor

    I'm sure you'll get a reply on the color bands quickly. My question has to do with the condition of the resistor you'e reading. Has it been exposed to excessive heat? Many times I've had the color bands CHANGE COLOR when the paint heats-up from a heat over-stressed resistor. Are you pretty sure...

    Diode Identification Help

    Your reasoning is sound, the markings on the component are not standard. "D' on the board is standard for denoting a diode. I'm thinking your component has proprietary markings (called 'house numbers" by most people here) That means the manufacturer of the board asked the manufacturer of the...

    Diode Identification Help

    I'm with davenn on this, a picture is worth a thousand words. It SOUNDS like it might be a diode, but it could be a transient voltage suppressor of some type, or some fuseable component. The components they're constantly coming out with keep us on our toes.

    effect of humidity on a PCBs

    Colin Mitchell's observation is a likely cause. There are a lot of other factors that can cause this: Compositon of the PCB board itself (does it absorb moisture), component susceptability to humidity, actual humidity causing moisture on the board that affects conductivity of signals. This is...

    Oscilloscope: screen seems dead

    Don't give up hope. Take a good careful look at the component area (and the contacts on your connectors) for burn marks, indicating obvious damage to isolate the fault. I always check for obvious damage before getting down to the nitty gritty. A lot of times you can isolate the problem quickly...

    Repairing Rancilio Espresso Machine - ID Trimmer Pot

    Haven't heard of the mfgr. What you will find when the pot arrives, is if it's the correct size and if the pins are aligned to fit the holes for your printed circuit board. Maybe the BENTENG company used the Bourns part number to signify an equivalent replacement? I'd just wait and see what you...

    Oscilloscope: screen seems dead

    If you've got a 'glow', I'd be looking at your horizontal and vertical drive boards, not the CRT itself. Any heat/physical damage to components in your horiz/vert driver circuits?

    Repairing Rancilio Espresso Machine - ID Trimmer Pot

    That's a Bourns trimpot. Look on the side of the pot for the model number, then add the 'W502' for the entire part number. For example: a Bourns Model 3296W-502 is a 5K ohm trimpot. Yours is definately 5K ohms. It's important to know the model number on the side of the pot to get the correct...

    Non working TV

    Yes, it sounds like a power supply problem. When you open it up, check the fuse first.

    Tektronix 2235 o-scope power supply smoke

    If I'm reading your post correctly, after the flash your scope was found to be functioning normally. If you lost a cap, it wouldn't be. I tend to agree with *steve*'s assessment. Combustible gas near whatever you were working on, an insect, something not related to the internal workings of your...

    Happy Birthday Davenn!

    I'd say 'older and wiser', but you're pretty much one of the smartest guys we've got here already. Happy Birthday Dave. Wishing you the best in health and happiness.

    Any idea what these are?

    Just in case you're still wondering, they're just the sockets for military specification connectors. There is NO resistor in them.

    Help identifying this device and tips to hook it back up

    The top line on the identification name plate has the model number. Google it and see if you can get more information about it.
