    pcb trace, common-mode noise, and murphy

    Are you considering 'outside' noise generators? Where is this 'panel' mounted? In some main rack housing with other circuitry that may be inducing their own noise into your panel? What else is your 240VAC connected to (some other motor or noise generator in another room?) Just something for...

    Panasonic appliances

    Check the owners manual (get one on-line if you don't have a print copy). This sounds like a factory 'error code'. Finding a manual or contacting the Panasonic on-line site, should tell you what the fault code indicates.

    help with a type of connector

    Hmmm, Looks like a modified spade lug connector. The modification being the little locking tab in the center of the lug. Typically, those locking tabs are a part of the outside plastic connector housing. Have you checked the auto-parts stores in your area to see what they have available? I...

    Double deck Technics RS-TR373 does not play sound

    I didn't look-up the deck, but my first thought is to check any possible rubber drive belts in the unit that may have deteriorated or become loose.

    Automatic Switchover from Car Speakers to Headphones

    BobK's pretty bright. I may have overcomplicated this, I've worked on a lot of sensitive systems and am maybe thinking of issues that aren't applicable here. BobK will probably be back on to straighten us out. What kind of wattage are we talking about here?

    Bridge rectifier melted.

    Easy boys. We've already got one user with burning bridges. We don't want to be burning any more of them between ourselves. I vote for the inappropriate heat sink.

    Halide flux on soldering can tarnish the soldering tip!

    That's a lot of information to try to answer. It seems to me that an 'aggressive' flux, would also be aggressive with whatever it was used on. I'd Google information on that particular flux, and see what others say about it. (Or better yet, contact the manufacturer and ask for application...

    help with a type of connector

    There are good quality bullet connectors and cheap ones. AND, there are good quality crimping tools, and lousy ones. Those trailer hitch connections, when done right, are pretty reliable. You're right though, a picture will help us better help you. And there are a lot of other good quality...

    help with a type of connector

    I use a lot of these when I add electronics in my cars. My first thought is that you were looking for spade lug type. They're just called 'adapters'. One female spade lug connector to two male spade lug connector 'adapter' (or vice versa) Thinking about it, I think you may be talking about the...

    Automatic Switchover from Car Speakers to Headphones

    Most systems that do what you want to do, just use the headphone jack itself (they're built to disconnect the main speaker feed when you insert the headphone plug, using leaf switches). The main issue, as you observed, is that the headphone connection is after the internal preamp, but before the...

    U8 spy camera

    Yeah. If it was built correctly, sounds like some kind of glitch in the command functions. Doesn't look like anybody else here is familiar with your unit, but it didn't hurt to ask here, there are a lot of pretty smart guys on this site. Good luck with however you decide to handle the application.

    U8 spy camera

    Wow. Apparently you have a lot more traffic entering your property than I expected. It sounds like it's a longshot, but does the manufacturer offer some type of accessory for this unit, maybe some kind of module the spy cam plugs into, that can supply continuous power? It really sounds like...

    U8 spy camera

    I've been thinking a little out-of-the-box on your issue. There are a lot of remote sensors, wireless and otherwise out there. A remote doorbell system for example that are relatively cheap. Would it be possible to rig a remote sensor trip at the point where traffic enters the property, to...

    U8 spy camera

    Good luck with experimenting. When I was a kid, most electronics were pretty robust, not that I didn't destroy a few things while learning. If you open this device up, you're going to find the circuitry almost, if not impossible, to rework by hand. (Your battery connections excepted). Try to...

    U8 spy camera

    Excellent explanation, thanks. I'm not familiar with this unit either, but it sounds like you've read about other people with your issue. Frankly, especially with your spy camera battery life and extended use application; I would personally look for another camera system to monitor your traffic...

    Golf trolley/caddie 12v DC motor controller

    I don't think this is an easy fix for somebody who doesn't do electronic repair. It sounds like you lost one (or more) of your semiconductors, which are the little black squares and rectangles on the printed circuit board. They supply you with the soft start and gradual speed increase. Do you...

    Power bank idea

    The only thought I have, is to avoid exploding your batteries. I'm not familiar with the 'power bank' term you're using. I've heard horror stories about lithium ion batteries exploding. I don't know if a 18650 battery is lithium, or if you plan to remove the 'couple Li-Ion batts' from the...

    LED replacement

    If you have the data sheet on the primary source LED, I'd use that for identifying a secondary source equivalent. Do you have the data sheet on the LED you want to replace?

    U8 spy camera

    I've re-read this post five times and I'm still confused. You've entered a lot of information in pretty short/combined sentences. Can you spread the information out a little, so we can separate each issue that you're seeing, and better determine why they're happening?
