    Old folks in-home personal alarm system?

    The parents aren't invalids yet. They'll only accept something that would help them notify one, of the other's need for help on the other side of a big house. I believe the problem is that the Gov't here subsidizes elderly care items, and those products are geared for a single elderly person...

    Old folks in-home personal alarm system?

    I don't know it is on your side of the globe, but everybody is sue-happy here. The lawsuit would go something like this: the elderly client did not realize when she purchased the product, that it would not notify emergency service providers outside of her own home. End of company providing the...

    time delay

    Check-out Time Delay Relay, and see if that will do what you want. Consider the 'Delay- ON' type.

    Old folks in-home personal alarm system?

    Yeah, everything I've seen in stores locally are tied into a commercail vendor, selling monthly service. My parents won't go for that. What I'm looking for is an in-house (THEIR house), notification system. KrisBlueNZ probably nailed the dilemma, big companies ensuring their systems only are...

    I give up - Cannot find documentation on PCB

    It may be a proprietary board to the manufacturer. Do you know what it came out of, what company made the equipment he board goes into? the LE (circled), may be the manufacturer of the board if you want to do a logo search. The edge of the board is marked LE-5-0 2806, the (200-00750 Rev A) is...

    Old folks in-home personal alarm system?

    My parents are getting up there in years. My mom fell in her bathroom on one side of the house at 3 am and couldn't get up. My dad couldn't hear her calling for help until he woke up himself at 5am on the other side of the house. I'm seaching for a (I think) simple wireless 'alarm'. Something...

    Corsair Cordless Trimmer

    I've got something similar, and dislike it for the same reasons. Battery won't hold the charge, won't charge when in use, generally an annoying piece of work. Unlike you, I went out and bought a replacement I liked better, and set the old one aside intending to look at it later (which I...

    Component help

    As a side-note, I think you should trace the circuit back, and find out what blew that cap. I don't think it died by itself. If you just replace the resistor and the cap, you're liable to just blow them again. You probably lost a semiconductor ahead of those two components, which caused the...

    Measuring IV Characteristics

    I don't know of a way to get a resistance or current measurement out of an 89410A. The instrument was designed primarily for making noise, burst signal, and phase measurements. Good luck with the project.

    Diode Identification

    I don't know if you're planning to just reuse them, or replace them. They look like they've been pressed-in. Sio they'll have a slight crimp around the edges at the metal plate. They're easy to dislodge, not so easy to replace the same way.

    Wire Wrapping

    I was hoping you'd get more info on this, so I wouldn't have to Google it for you. Being an old guy I have a good supply of wire-wrap stuff and haven't been needing to buy any for years. My SIP (single-in-line package) posts, including individual posts came from Mill-Max and Samtec. I don't...

    I've got to do something with it.. can't just leave it hanging

    I think *steve*s idea is the best bet. I believe flippineck wants NO antenna hanging down. I think the hanging antenna is what snagged his chopper in the first place. I can't think of a way to just get the antenna out of the way (by wrapping it around the tail section or something else he...

    I've got to do something with it.. can't just leave it hanging

    I like *steve*s idea, but if that doesn't work, is there a possibility of hanging a small weight on the end of the antenna, so is stays down, and doesn't get caught-up in the helicopter when it makes a rapid (hopefully under control) descent?

    Composition of 1970's TRW Series HEW Capacitors?

    Well, the recoder is running fine, so the metallized polyester caps are doing the job. Thanks for the info on what became of the TRW cap franchise. I couldn't find much on-line when searching for cross reference information. It's good to know who took-over from the TRW company product.

    Dual inductor/single core question

    Sounds like the frequency may be causing the inductor coils to vibrate. (Or possibly an actual ambient temperature change where you're at, from winter temperatures to summer ones). Have you considered 'Q-Dope', or some other laquer from a place like GC Electronics, to hold the inductor coils in...

    Intermittent Operation!

    Is your radio designed to drive six speakers? Was this a factory-installed job, or DIY? Are the speakers the correct ohm-rating for your radio? I agree it sure sounds like the radio has a problem, but I wonder about the load it's looking at. The interaction of any cross-overs between the...

    Replacing paper capacitors

    What duke37 said. I had a similar issue question last April. I used metallized polyester replacements and they worked fine. 1970's era equipment.

    Mystical Welding Powersupply

    Not much to go on, but he's my input: The oil-filled can capacitors last a very long time. The big blue electrolytics, not so long, especially in high heat applications (like an inverter). I'd check the bridge, just to be sure. Almost all of my inverter failures are because of blown...
