    solar panel power loss

    Hmmm, ok Trobbins, who are these 'well-made' panels? I'd like to investigate this. I live in the Arizona desert, the sun kills 'em quick here. I'd guess they might survive longer in less hostile environments, but not by much. I keep reading the technology is getting better, but that's kind...

    solar panel power loss

    Another thing that people don't talk about, probably because it's not politically correct in today's 'go green' mentality; is that solar panels have a limited life expectancy. How old are your panels, their output degrades with time. 13 to 15 years is peak efficiency. Considerable degredation...

    Timer problems

    Another idea, if you're looking for possible alternative, are Time Delay Relays (TDR's). Wide variety available, adjustable on and off times. Just a thought.

    Identify a diode? Capital H

    I used to work for Hughes, before they got bought out by Raytheon. We didn't mark anything 'H', all by itself. And I'd be real surprised, if we made stuff for Honda.

    Placing connector on AC/DC Adapter

    Yeah, and I've seen manufacturers use-up their old stockpile of left-over parts from previous production runs (like connectors with more pins, than their latest production run needs). So it sometimes happens that you get a 4-pin plug, when all you need is 2 or 3 pins in the model you have...

    indirect band gap semiconductor doubt ....

    Trivia. Germanium originally used because it conducts at .3v Silicon conducts at .7v Silicon more likely to be damaged by static discharge (or EMP), when they talk about 'hardended' electronics for military, they're talking about germanium devices, which are less prone to such damage. Doesn't...

    Identify a diode? Capital H

    My guess is, it's a proprietary part, 'H' for Honda. If you can't get a schematic, or talk to somebody who repairs this module from Honda, you're probably SOL.

    DIODE COLOR BANDS

    I've had to do this before a few times, and it's a pain. Look up color code for diodes on Google, you may have to reword the request a few different ways. Different mfgrs mark the things different ways (because of all the odd-ball country manufacturers). I don't remember for sure, but I...

    Digital Counter triggering.....

    Mfgr, model number, any info off the ID markings on the counter, ...and exactly what it is you're inputting (what kind of signal). Are you sure you got the right kind of counter for whatever signal you're inputting?

    Re: Cable box is making a ticking noise

    Hmmm, Jamie may have a point, although not in the way he meant. The cable company input signals may be different from one company or city to another. The company you're using now, my be injecting a signal onto their cable, to operate some function, that the box from the other city may not have...

    Replacing reversible 180 degree rotating cassette tape heads

    You need an alignment jig, that factory repair techs would have. You will be particularly annoyed, trying to realign this eyeballing it. I'll mention, unless your heads are actually worn-out. Check the forward reverse switch down by the heads (the actual switching mechanism). Many times, the...

    Need help identifying a component

    You'll open the 152 degree thermal fuse quicker than the 168 degree. Your unit was designed for 168 degree cut off, ...you're wasting your time (and you'll soon have to replace) the 152 degree device, if you install it. It won't hurt your dehydrator, but it'll cause you aggrevation, having to...

    Re: Cable box is making a ticking noise

    I don't know, but I'm wondering if it's a power supply problem, why it would stop when the coax cable is disconnected? Relays can look like pretty different these days. Can you isolate the sound to a particular device, with the cover off?

    Moving my hand closer to the circuit changes it's frequency

    Holy cow Zander, I got enough of my own problems, without taking on this bear. I don't think an op amp is going to filter this, it COULD actually compound the problem. I may be barking up the wrong tree, but I believe you are overcomplicating this, because you're looking for a frequency...

    RCA VCR VR651HF Loading Motor Source

    Incredibly smokin' deal, if true. With models changing every year, (and VCR's going obsolete) the parts availability is a real issue.

    Re: Cable box is making a ticking noise

    Sure sounds like a relay to me. If you got the box from the cable company, call them and report it. If it's your own, contact Scientifica Atlanta, and explain the problem. Who knows what all else is in these boxes these days, that would trip the relay but not interfer with your signal (for...

    Need help identifying a component

    It's a concern because the nature of the dehydrater, is to turn it on, and let it run for extended periods of time. If something happens, and you forget about it, there could be an overheating problem. Seems a slim possibility normally, but I wouldn't risk a fire when it's easy to eliminate...

    Moving my hand closer to the circuit changes it's frequency

    We could theorize all day. I'd give your idea a shot, and see how well it works. I just want to reemphasize: If you're working on a bench close to EMI source(s), that location may have different characteristics, than where ever your final installation would be. Your shielding will be the...

    replacement transformer

    If you're still monitoring this post: Contact some elec fence manufacturers, and tell them your problem, with any information you might have on your electronics package. People install these systems, and they're exposed to the elements for years. When they fail, nobody can read the original...
