    Induction cooker pans?

    Methinks there is a lot of theoretical over-analysis here. Mayhaps a pot manufacturer would specify on the outside of a newly purchased sales box, whether or not the pot would work on an induction-type stovetop(?) Again. With so many of these stoves in common usage. I would think a pot...

    Salvaging Parts

    I'm old-school, but when I desolder, I attach a 'heat sink' to the lead of the device I'm desoldering. They're just metal clips that will absorb much of the heat the device might be subjected to during desoldering. You can buy heat sink kits (that offer several different sizes), use an old...

    Toshiba 32BV701B audio fault

    My experience with this type of problem is that one of your semiconductors interrupts the circuit when it gets hot. The quick and easy way to isolate the problem is to buy a can of 'freeze spray', and individually hit each suspect semiconductor. Your sound will come back when you've got the...

    Loose contact inside potentiometer

    I know you don't want to do it, but it sure sounds like you're going to have to replace the potentiometer to eliminate the problem. If you find replacement pot, I'd order a spare or two, so you have them, when this problem occurs with another pot on your board. That's the only solution I can...

    New Member, New to Electronics, Looking for some help!

    Yeah. I think you need to supply more specific information about what you want to do. I'm thinking you want something that rotates at a slow speed, as in some type of display. As opposed to motors running at a couple thousand rpm. (but we don't know that). We need specifics to see if you need...

    Induction cooker pans?

    I don't KNOW, but my brother had one of those stoves and he SAID the older aluminum pots wouldn't work on it. With so many of them in use now, I would GUESS that pot & pan manufacturers would have made allowances with aluminum and stainless steel pots, so their wares would work with all types of...

    Loose contact inside potentiometer

    I'm not there to twiddle with it. I'm trying to help with diagnosis based on the informtion you report. Now you're describing something like a static electricity build-up that you're discharging to solve the problem, which would seem unlikely. This is my input. You've either got an unreliable...

    Ancient 5 1/2 digit DMM - voltage with floating inputs?

    Like duke37 said, if it has a tube or tubes, I'd suspect them first. It would be wise to clean contacts, but it sounds to me like if it's not using vacuum tubes, a capacitor is leaking and needs to be replaced. Good luck with the project.

    Loose contact inside potentiometer

    If you've resoldered the leads, and you're sure the circuit-board trace is not broken near the pot, it sounds like the pot itself is on the way out. If the inside of the pot is accessible, you may be able to spray it with the thin tube that comes with a can of contact cleaner, and extend its...

    Advice needed on "smart" helmet

    Yeah. I thought he noise-cancellation issue would be a prevelant problem that manufacturers would have compensated for by now. I can imagine jshfchtr's annoyance about wind-noise above 50mph though. I would hope he gets a workable solution from advice here.

    Loose contact inside potentiometer

    Don't have a good answer you'll like. It does sound like the pot is your problem. How sealed is the pot. Any possiblility of using a 'SAFE FOR PLASTICS", spray contact cleaner in there, to see if that helps until you actually break-down and replace the pot?

    Need help identifying part, possibly a resonator

    May not be much help, but muRata Ceralock ceramic resonators have the Large 'C' with a small 'm' inside of it as their logo. Might that be an 'm' ? They DO look like resonators to me.

    Advice needed on "smart" helmet

    I'd pay attenion to he 'actual application' or 'practical' sde of this in your consideratios. You'd want to make sure whatever you use, doesn't over-power the traffic around you for your own safety. I was thinking about the VOX-type applications, where input is squelched until your system...

    Moving electronic part/switch/relay - does this exist?

    Considering the size required, Gryd3's idea of piezo elements sounds feasible. I'd look around, and see what might be available there.

    Yamaha RX-V795a Receiver doesnt power on

    And you didn't even need a manual. You're getting all kinds of experience. Pretty soon you'll be suggesting help for other people asking questions on this site.

    Yamaha RX-V795a Receiver doesnt power on

    Yeah, I checked your link. They want you to click on some 'sign up' selection. I'm not letting whoever is running the site into my computer. Your symptom now seems to be that your receiver does power-up (for less than a second), and then immediately shuts down. And you mentioned it has...

    Yamaha RX-V795a Receiver doesnt power on

    Yes, on the capacitors. 9611 is made in the year 1996, 11th week of manufacture. They're probably still good. A more thorough check of the semiconductors would be made out of circuit. But I wouldn't do that unless I found an obvious bad one. What I'm trying to do here, is give you a quick and...

    Trying to find an appropriate socket for an IC

    Good luck finding what you want. I've been having a lot of problems finding sockets too. Manufacturers are turning-out most surface moount devices now, and the companies that made sockets (:Mill-Max, Aries, Samtec, the guys I used to buy from), have really cut back on what they offer now. I've...

    Yamaha RX-V795a Receiver doesnt power on

    I'm checking this thread once in a while between my own work here. I wanted to make you aware of one other thing while you're troubleshooting: I can see that you're not shy about disconnectng the power semiconductors from heat sinks. Be aware that the white goo, is thermally conductive silicone...
