• Little Project - a 2-Level "Porch Light"

    From 186283@ud0s4.net@21:1/5 to All on Sun Jan 26 04:07:10 2025
    My front porch light, motion activated, developed
    a 'fault' long ago - one I *liked*.

    The motion sensor did NOT cut off entirely.
    This left the bulb running at like 25%
    power all the time. IF motion, then it'd
    go to 100%

    This was actually GOOD.

    Alas this fixture is OLD - and has now
    trended towards "blinking" if the temp
    goes below 50F.

    Bought a new 2-bulb fixture. It's "dumb"
    but I want to smarten it up.

    My PLAN is to add a motion sensor, but
    to ONLY one bulb. A rather low-watt
    yellowish "bug bulb" will run ALL the
    time. A bright 18-20 watt LED bulb will
    be attached to the (added) motion
    sensor.

    Doesn't seem TOO hard.

    I'm not adverse to weird wiring or
    drilling holes in things.

    BUT - any advice/notes ?

    The choice of the add-on motion sensor
    especially. Need nearly a 180-degree
    sensitivity and a great service-life
    profile.

    Um, sorry, this doesn't need Linux or
    micro-controllers or anything - just
    real-world simple stuff. LONG life
    is the goal.

    Likely one bad capacitor on the board that loses its ability to store
    charge in low temps. Given the 'blinking' it is most likely the
    bootstrap cap. which allows the main supply regulator chip to start up
    to power the "motion sensing" parts.

    I had a TV once that needed a good slap to get the colour working.

    I opened it up and found they had used EYELETS to form vias. None of
    them were soldered.

    I soldered a few and the colour came half back, Then the penny dropped,
    and I soldered every single one on both sides of the boards.

    The TV was flawless until it got a direct lightning strike.

    It's the same with electrolytics of a certain age, and RIFA mains filter
    caps. Justreplace the fucking lot.

    Probably that fixes about half of all 'dead' electronics these days

    I've been using these:

    amazon.com/gp/product/B0CCF3HYT9

    The sensing angle is about 100 degrees but you do get six of them along
    with mounting brackets. Also the output is digital not analog. There are a number of other options but I think the all use the same sensor. It's adjustable for range and sensitivity.

    https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/ overview

    has information on how they work and some of the adjustments. The ones I
    have are very close to Adafruit's new design. Follow the pages and there
    is a simple diagram with batteries, the module, and a LED, no Arduino. You could do something like that but drive a FET to control the main LED.

    Look nice - but this app is 120vac all the way.

    Alas all the little ones are rated for 40w max, which
    is fine if you stick to LED bulbs, but SOMEBODY might
    stick a filament bulb in there someday.

    About the physically smallest I came upon early is a
    RAB Lighting SMS500W ... but it still uses a 1/2" hole
    and would hang out under the light unit. We'll see.

    There's only SO much room in the enclosure.

    Some solid-state 'relays' are fairly small,
    though still need to be heat-sunk.

    For safety, I'll have to go with like a 300w capacity
    minimum. You can still buy 200w A-series bulbs. They're
    bright and very nice, but DO suck up the power and
    get hot as Mex tamale shit.

    There's tons of stuff for the electronics hobby market,
    but for real-world line-connected there's not as much.

    Gonna look around a bit more. Mouser ? Newark ?

    Due to forger probs elsewhere, I may need to
    add "WokieSux" to my name/address ... so don't
    be surprised :-)

    It takes 3 D cells and they last a long time it the raccoons don't hold a square dance on the deck. I first bought one to try to dissuade the coons
    but they like to see what they're eating and thanked me for the improved ambiance. Then as the days got shorter I realize it was a lot handier than fumbling with the lock like I'd been doing for 30 years. The cat has
    worked out the coverage and seldom triggers it.

    When the batteries are getting weak it triggers repeatedly which is as
    good as an additional low battery indicator. I had one of those on a LED flashlight and it earned its keep by draining the battery so it could show
    how well it was doing its job. later iterations of the flashlight skipped
    that 'feature'.

    That product number brings up a LED flashlight
    in the USA :-)

    Yea, I could BUILD something out of parts, but
    not sure my insurance company would be very
    understanding. They expect certified components
    dedicated to the exact task at hand. Fascism.
    Strictly, my whole lighting unit AS A WHOLE is
    UL Certified - but not any mods.

    If you paste the url fragment above into the url bar, you are taken to
    the amazon page for "Beams MB360XT 200 Lumen Wireless Battery Operated
    Powered Motion Sensing LED Spotlight, 2-Pack, Brown" lights in the US.
    Which is not a "flashlight" -- as in not portable/handheld.

    Common misconception propagated by internet trolls who don't know
    better (or do, and want to propagate it anyway). Read your detailed
    legalise packet, you likely won't find anything of the sort.

    Interesting. I get

    "Beams MB360XT 200 Lumen Wireless Battery Operated Powered Motion Sensing
    LED Spotlight, 2-Pack, Brown"

    along with the information that I purchased them in January 2023. I bought
    the first one at the local Ace Hardware but they were out of stock when I
    went back.
