    How do I reset a scd power 832 when both key pads are locked in program mode

    Good find on the video, Harald. I've never seen a DSC 5010 Panel defaulted that way, but that's probably because I've worked exclusively in North America. Alarm panels used in the UK and Europe, and presumably Eastern Europe, have different standards and I'm guessing that the panel in the video...

    How do I reset a scd power 832 when both key pads are locked in program mode

    DSC Power 832 is actually a series rather than a model nomenclature. It's almost always a model PC5010, which you'll find printed on the door of the steel cabinet that houses the Control Panel. If the model number is something else, this would be the time to mention it. It might be helpful to...

    Woo-Woo LED Magnetic Lighting: Is it for real?

    I found those vids on YouTube. I expected to find I've seen lots of fake perpetual motion and "free energy" vids, but apparently variations of winding copper wire around a stationary magnet is now the latest "free energy" craze. I can see a couple of ways off the top of my head to fake that...

    Fuse for DSC PC3000 1AMP

    Harald is correct, there are generally no "alarm specific" fuses, they're all standard low-voltage stuff. Most are the glass tube with metal caps type like those on your PCB. The main electrical rating to look for is current, i.e., Amp rating. Any 1A fuse will work if you can make it fit into...

    Unknown electronic part that I found

    I'm seeing a picture of a PCB, but I can't identify it.

    What happens if you connect 2 isolated power supplies backwards?

    Depending on the kind of batteries and size you use, it will likely damage stuff outside the circuit, including the immediate environment and the experimenter.

    Proximity sensor for parking

    That's brilliant, but naw....too simple, and doesn't involve any cool electronics. Electronics people love to make things complicated....;)

    Microwaves to destroy termites in wood

    Good point. I suspect that it would be easy to build or adapt an existing microwave generator that would kill termites in wood. I also suspect that it could ignite some wood in the right circumstances, and could leave it smoldering quietly inside walls, but I don't know about that. I didn't...

    Microwaves to destroy termites in wood

    Very quick uick Google search: Apparently microwave and high voltage technology is somewhat effective only with "drywood", which I assume is wood with a low water content. From a quick scan, it looks like it's only effectively used in tropical areas like south Florida and southern California. I...

    adheasive backed foil tape

    There's more than one kind of adhesive backed foil tape. I did a quick scan of "adheasive backed foil tape" (sic) on eBay and found a variety of different types. I often use eBay to search for something I'm not familiar, because they usually have informative pix so you can see what you're...

    Magnet pole pieces...

    What hevans 1944 said,. Plus, sorry I didn't think to mention this before, since I suggested buying lots of small neodymium disc magnets, but these small powerful magnets are NOT TO BE USED around children young enough that there's a risk of ingestion. Swallowing a magnet is LOTS more...

    Magnet pole pieces...

    The force on (presumably unmagnatized) iron is always toward the ends of the bar(s). There is no force drawing iron anywhere except toward an end. The magnetic field is from end to end: No magnetic force emanates from the bar between the poles. This is easy enough to test: You can buy 100...

    DSC 1832 - self monitoring call out # causes communications trouble

    Hi Videopete, Very sorry I somehow missed your post back last year. Not sure how that happened. Anyway, if you're still here, take DigitalPigeon's advice: That's exactly what I would have recommended. I retired before the Envisalink series was available, so DigitalPigeon is probably more...

    How can I connect this microphone and recorder to AA-batteries?

    It might help if we could see a clear picture of how the PCB is labeled. I can't really make out any of the labels from the pictures provided.

    ridiculous harvest

    I guess it depends on where you are and how much effort you put into it. About 10 years ago, I spent part of a year in Costa Rica where you could buy a fresh ripe pineapple for about 0.5 USD; so no, I wouldn't have put that much bother into it.

    What did we do before LEDs

    What (*steve*) said. I live in the Wash. DC 'burbs and in the early '70's my wife and I used to go see a house that did this every year, one of the first that started the tradition. Back then, it was simply outlining the entire house in red (incandescent) lights, but they added something each...

    Doorking gate entry system

    I once fixed a Kenmore washing machine by replacing a burnt resistor in the power circuit. When I found the schematic for the PCB, same model but updated, I found the resistor that had burnt was rated for 2W and the newer PCB version now used a 5W resistor ( same Ohm-rating). I replaced it with...

    Old remote control repair

    If by "another source of power," you mean a backup battery, then no. I know we often refer to the RF Receiver & Transmitter(s) as "garage door openers", but they're not. The RF system is a wireless switch for the garage door opener, which is a line-power electric motor that opens the door...

    Old remote control repair

    I used to work with Linear RF receivers & transmitters back in the 70's. The same units that activated garage door openers was state-of-the-art for home security systems back then. Look at these two examples of D-67 Linear receivers from eBay and see if they look like what you have. I had to...
