The camera I have is this one, which costs about $110 each.
https://www.amazon.com/dp/B08LKL4TR6
 
Since that's over the OP's budget, this one one is cheaper.
https://www.amazon.com/dp/B0BGS833VR/
It has a 3x zoom lens, but a lower resolution camera
(4k is still pretty darn good for basic security needs).
 
Either one would typically work in normal day/night security norms.
If that's too much money for the OP, this should work
https://www.sannce.com/products/c500-poe-ip-camera
(but I have no experience with it).
 
It is only 5 megapixels (2592 by 1994 pixels) but that is still better
than high-definition television. They have free returns if it doesn't work
out for the OP.
 
I would suggest a 4mm lens instead of the wide angle (2.8 mm) lens.
This will go a further distance which is often needed in such cameras.
And the bullet form will probably be better than the turret form.
 
The OP can put in a microSD card and it uses a POE & CAT5 cabling.
The OP will likely want to connect it directly to his home router.
It will probably involve drilling a hole in the wall to get outside.
 
Does anyone else have experience with these security camera setups?

There are quite a few off-shore assembled circuits that will do what you want but will not fit in the space. Additionally, they typically need a small amount of DC to work the circuitry. There are several I've used and they work fine. Since you indicated an additional waterproof box is not desired, I suggest a box extender and possibly one of those cards. No matter what you do it's gonna get crowded in there. Oh, BTW, there are some programmable DIN rail mounting devices as well for mounting closer to the breaker box. Yet another idea is to add Z-Wave (Smartthings) to your home to automate this and other devices in your home. Replace that wall switch with a z-wave and you can at least turn it off and on remotely. There may be a way to add a turn-on delay as well depending on the switch.

Hi Klay,
 
Thanks for the extra input. I have found from another group
that a Omron H3Y-2 would do the job. Already ordered one
at a very good price. Once I have in my hands I will determine
a best fit for the existing box. It it is a challenge I will
swap it out for something else that will work. With the socket
for the Relay Module it is only about 3.4" high and it might fit
laying it on it's side. If not a 4" square PVC box should work.
 
Time will Tell!!

Your break even point (cost of electricity saved vs cost of
Omron) comes out to about 4 years using rough estimates:
12 outages per year; 6 hours 27 minutes per outage;
15.5 W LED floodlight; $0.23 KWH average.
You can come to a more accurate number using the specs that
apply to you instead of the averages I used.
 
That assumes your cost is $10.00. It won't be, using the
Omron. You'll need to buy the proper fittings/rails/enclosures/
wire etc. You'll need to install it in a dry location - ie
indoors - which can add construction costs. If you jury rig
the thing it will likely be unsafe, and definitly be unsafe
as far as the NEC is concerned.
 
The best solution - if it exists - is to buy a floodlight that
is programmable the way you want it. What you (and I) have is
designed to be programmable via an on/off switch to do exactly
what you describe: a real brief power interruption turns the
light on until either the sun comes up or you turn off the
switch; an extended (several seconds) power interruption
enables the light to respond to motion. You can find the
description of that buried somewhere in the documentation that
applies to your light.
 
The REAL question is what is it worth to you to do about it?
I understand the attraction of looking for a "gizmo" to modify
what you've got. It can be hard to defeat that attraction.
Cold hard reality can help. Run the numbers for your floodlight
in your location. Think really hard about whether making things
unsafe - or potentially unsafe - is worth it. Think about how
much time and effort you have to put into it. There does come
a point where it is no longer fun.

THis may be the best solution but one will be hard pressed to find an outdoor light that is programmable in the way he wants it. Searching for the perverbial needle in a haystack. If there are any.

Hi Ed,
 
I totally understand your thinking. Being a Electrical Contractor for
far too many years and now I that I have sold the business and basically
QUIT!! I now have every day as Saturday and this is just going to be
FUN!! And at my age of in excess of the national average of males.
 
My cost on the Omron and parts will be about $25 and any needed wire
and fitting is already in my old stock. The biggest bonus will be
that if this all works as planned will be not lighting up the
neighborhood all night long. :-) Especially if I am on a overnight
road trip and wouldn't know it happened until I got home and was
informed by others of the issue.
 
To me it makes more sense taking on the challenge this way rather than
searching for a Motion Head that will not do it or has the ability to
program out the ability or some new fancy AI BlueTooth thingie that
will do it my way. I see that as wasting my time and it would more
than likely cost a lot more.
 
Again Time will Tell!!

Well, after Jim's answer, I watched the app, and the app stops playing
in less than 2 seconds. When I have the radio go back to pplaying, if
the app restarts playing -- sometimes it doesn't -- it takes less than 2
seconds

And Aramco itself is also responsible for 2 oil boycotts of the USA and
for raising prices for political reasons. I understand that they have
only so much oil and eventually they will be like a 50-year old football
player, who should have made as much money as he could when he was
younger, but it's the political reasons I object to. And I'm sure they
have not stopped, despite their feel-good radio commercials.

They do play an ad at the beginming, but also in middle. Sometimes
tthey seem to go longer, but on those two stations every 10 or 12
minutes and since they play the very same ads on each, for Saudi Aramco,
for some brand of mayonaisse, for WGU online college, etc. I'm sure
Tunein is providing themn.
 
They may play many fewer when it's C-span radio or an NPR station,
because I suppose they get those stations for free or almost for free.

If you have a bench grinder, every nutdriver has a thin wall nutdriver inside it.
Use a hex bit in an electric screwdriver to spin the workpiece, it's steadier than
simply handheld grinding.

My camera has an option for uploading to the cloud, but that is optional.
 
I have a 256 GB microSD card in it, and I can access the camera using my
local intranet. It was $110, which is outside the OP's target price, but I
wanted the 12 megapixels to see license plate numbers (day and night).
 
Given they're made for cars, the OP might consider a cheap $50 dashcam.
https://www.amazon.com/gp/product/B0B7WND1G2/
 
Another option is to connect a Tesla coil to the vehicle that only
activates when you park it out of the way. Non-lethal, non-damaging, but
surprising and unpleasant. Along with the flashlamps and sirens.
 
Even better is to rig a can of spray paint and some mace. :)

The light is designed to stay on if the power is interrupted momentarily. Your installation is not the problem. Either a new light or design a circuit that resets the power automatically.

Hi JoeC,
 
That is what I am looking for but to just hold off turning the power
back on quickly. A small Time Delay Relay that on power up puts
the Motion Detector unit back into it's normal operation.
 
Basically the same as I do with the power switch in the garage but
without my mental strain!!!
 
I just need some device that is small enough to fit the 4" round box.
 
Thanks for your interest in the challenge.

I have had multiple sensor lights that would do that.
 
The light is probably designed to lock on if you turn it off and on
again quickly. So making sure the power stays off long enough would
disable that feature and do what he wants. Then, you would have to
disable the fix to keep the light on for Halloween.

Hi Bob F,
 
You are most likely correct that the quick off/on is built into
the circuitry to give that ability. I had not thought of that
before. However, Mother Nature does know and just wants to punish
me for some unknown reason. :-(
 
BTW The Halloween issue is a non-issue here!!!
 
I would think a small Delay <On> Timer for 30-60 seconds would fix the
problem. It just needs to fit the box.
 
Thanks,

ABLE1 <somebody@nowhere.com>: Jul 29 10:21AM -0400

Hello,
 
I thought I would post this question here to see if someone can assist.
 
I have a outside flood light on the soffit at about 16 Feet AGL with
a motion sensor that is mounted at about 8 Feet AGL that is powered
24/7 from a 120VAC Switch inside the garage.
 
That is until Mother Nature throws a lightning bolt ⚡💥and zaps the
power off for a second or two. When that happens at night the motion
sensor head powers the lights on until I happen to notice and flip the
switch off for about 5 - 8 seconds and then all returns to normal,
otherwise the lights stay on until the Sun comes up.
Which is not needed and cranks up the electric bill!$!$!
 
I could tear all the Romex wiring apart, install a water proof box,
wire in a Time Delay Relay so that when the power comes back on the
Motion Head is not powered for maybe 30 seconds or so.
 
However, that seems like a lot of work and there should be a easier
way!!!
 
So, anyone have a thought or solution that would fit inside
of a 4" Round Weather Tight Box that the Motion Head is mounted on??
 
Or maybe some other thoughts that would make it a simple fix??
 
Maybe some small Electronic Circuit thingie that would fix the problem.
 
Thanks for any hints.

We poured distilled water through it and let it dry overnight (SoCal,
we're having a heat wave here). One worked. One partially worked, so
I'm going to be less gentle with that one and let it dry longer. Yeah,
we have half a dozen waiting for revivification.
 
The differences are interesting. On one the top just goes on easily.
On another you have to fit the bottom (closest to the spacebar) part in
first and remove some of the keytops and even then there's some magical
thing that we're missing.
 
And how many nutdriver sets have a thinwall 5.5mm or 7/32? FEH!

I experimented with MP3 CDs but I pretty quickly transitioned to USB thumb
drives, especially the little fingernail-size ones. I still have some of those
but these days I almost always use SiriusXM. I have a single subscription that I
use (via Bluetooth) in both vehicles, the office, the living room, the back
porch, the garage, and everywhere in between since it runs on my phone.

Same here. I don't use CDs in the house, as well. My fancy Technics 5-disc
changer hasn't been out of its box in 15-20 years, and none of my computers has
an optical drive of any type, although I do still have an external CD/DVD drive
in a drawer, just in case. I haven't needed it in years.

My 2016 Kia and 2017 Toyota, both bought new, still have CD players. I've never
used either of them.

You can try opening it up and giving it a good cleaning (all of the
keys and switches, and the PC board), rinse and dry thoroughly, and
check to see if there's a fuse on the PCB which might have blown.
There were quite a few different M models with different PCBs and I
haven't been able to find schematics, so you'd have to inspect the one
you have.
 
If the large IC (the keyboard-control microprocessor) was damaged, you
might be able to repair the PCB if you can find a parts donor (same
M model) on ePay or elsewhere.
 
>2. What's the best new replacement?
 
If you like the buckling-spring design used in the M (as I do), check
with Unicomp. They're still making a couple of models of bucking-spring
keyboard (standard and mini), with both USB and PS/2 interfaces available.
I think they used to offer a repair service for Model M keyboards but
I'm not sure it's still available.
 
I'm typing this on a vintage-2001 Unicomp.
"Peter W." <peterwieck33@gmail.com>: Jul 27 04:06AM -0700

I have had some success with vintage keyboards simply putting them through the dishwasher - keys down, upper rack, 1/3 the normal detergent. But, be sure the unit does not have an exposed heating element or you might melt the keyboard. Newer keyboards do quite well as long as they are not self-powered (battery type).
 
Remember - the alternative is landfill, so heroic measures are justified.

Yes, Toyota factory radios tend to have the CD changer port. I've never seen
anyone actually connect a changer there, but I've seen and helped install 15-20
adapters of varying kinds for people who wanted an aux port or a USB port or
even BT. It's a handy port. I hope other car manufacturers do similar.

A real radio doesn't connect to a hotspot. It receives radio signals.
So what are you talking about?
 
Hotspot usually refers to a Wi-Fi hotspot.
 
Perhaps the "real" radio is an internet radio?
 
If so it's up to the software or app running in the "real" radio what it
sends back.
 
ON the other hand perhaps you are referring to a bluetooth connection
from the phone to the "real" radio which is acting as a Bluetooth speaker?
 
In that case the app in the phone may stop or pause when the "real"
radio disconnects, or it may not.

Adnan Khashoggi is, as far as I know fine. Perhaps you mean his nephew
Jamal?

What radio station are you listening to using Tunein Radio?
As far as I know Tunein don't add their own commercials, except maybe at
the beginning immediately after you choose and start playing a radio
station, though it's difficult to tell, some of the stations do that too.

To me, 'hotspot' implies WiFi, but I have no experience with streaming over WiFi
so I'm going to talk about Bluetooth (BT).
 
I frequently stream SiriusXM via BT from the SXM app on my phone to the radio in
my pickup, the radio in my garage, or the music system in my home theater. When
I'm streaming via BT and I turn off the receiving device, the SXM app
automatically switches to Pause within about 1-3 seconds.
 
It's clearly a two-way protocol. I'm not sure how my experience relates to you
and your situation, if at all.

You're right, Hotspot means Wifi. And yes, I was talking about
Bluetooth. I'm glad you figured it out, and I'm glad I gave details
about the phone and the car. :-)

Wow
 
I guess I should look at the app when I turn off the radio. Usually
I'm driving and try to distract myself as little as possible, but I
could do this while standing still too. Also usually the map is showing
on the phone, so if Tunein shows that it has paused, I wouldn't see it.
 
I guess I could have thought to look without posting here, but it did
not occur to me (Sometimes it's hard to believe I'm as smart as my
mother said I am.) I've been in the car from Thursday night to Monday
morning. About 600 miles. Plenty of time to have thought of this but I
didn't.
 
Tomorrow I will watch the phone app while I turn the radio off.
 
I also got a new map DVD in the mail today.
 
 
>It's clearly a two-way protocol.
 
Wow. Those people who make this stuff are so clever.
 
> I'm not sure how my experience relates to you
>and your situation, if at all.
 
It's directly applicable. Not necessarily binding, but I bet mine works
like youre does. The situation is the same. If that's what's
happening, it's pretty stupid of me to change to FM and then change back
again just to pick up where I left off with the same annoying commercial
I tried not to hear. LOL
 
 
 
Thanks, Bertrand. I waited to answer you until I got an answer I liked
better!

BTW, I started the car where there was** no cellular signal. I forget
if I had turned off the phone or the app. And Tunein played for a full
10 minutes just on previously buffered data. IIRC my phone has 64GB of
storage and maybe that made a difference.
 
 
**I went to Jamestown, Yorktown, and Norfolk and I think they all had
good coverage but north of there and south of Waldorf Maryland is very
rural and there were a lot of areas with no T-Mobile coverage and not
that much Verizon or anything else. The FM radio still worked,
however, and AM though no station I liked.

Well, by golly, you were exactly right. Sitting still I could watch the
app go to Pause in less than 2 seconds after I switched from CD Changer
(Bluetooth)** to AM. More than half the time it would switch back to
Play when I switched the radio back to CD Changer.
 
**This is a car and radio from 2005 and didn't come with Bluetooth.
GTA Carkit has add-ons for many older cars to connect the phone to the
radio, to play phone calls and webradio through the much better car
radio speakers. I think it was about $140 and well worth it. Also has
an AUX input. There might be another company that sells something
similar.
 
It works in my and I think most cases by plugging into the CD Changer
jack in the back of the radio. I didn't have and didn't want a CD
changer anyhow.
 
If the phone is on and has once been paired with the car, it connects
when the car is turned on. If the car is on, I think one has to do
something on the phone when you turn the phone on. I've noticed that
bluetooth is so clever that when I'm wearing bluetooth headphones and I
turn the car on, the car takes over the bluetooth without my doing
anything,
 
I could have known bluetooth was 2-way because, when I turn the car off,
or turn off whatever the phone is connected to, the sounds from the
phone either switch to the phone's speaker or stop altogether. Of
course changing from CD Changer to AM or FM is not the same as turning
the car off, and it's still paired and connected because when I press CD
changer again, it starts playing in under 2 seconds (in those cases
where it restarts on its own.)
 
So all those times I thought I was killing time until the ad was over, I
was just fooling myself! And though the same ad is played 5 or 6 times
an hour, at least it's not so omnipresent that every time I switch back,
another copy of the ad is playing.

Coincidentally, I just bought a reel of BF998s, which are the last
remaining dual-gate MOSFETs, now LTB, alas.
 
I don't use a whole lot of them, but the amount of design space I've
been losing lately due to EOL parts is pissing me off.
 
The worst was the BFT92, which was almost ten times faster than the next
fastest remaining PNP (5 GHz vs 600 MHz-ish).

micky <NONONOmisc07@fmguy.com>: Jul 25 06:04AM -0400

When a cellphone is a hotspot and it streams web-radio to a real radio
(in this case the car radio) is there any feedback from the radio to the
cellphone or the app that is running? Would the app know if I had
turned the radio off, or changed input so it was no longer detecting and
playing the cellphone signal?
 
It seems very unlikely to me, but I can't keep up with new advances in
tech. And it would account for what seems to be happening.
 
Specifically, I listen to CNN or MSNBC on the Tunein app and it streams,
is that the right word, through the car radio. The free version of
Tunein is free but you pay by having to listen to mannnny commercials.
 
One in particular annoys me. It's a commercial for Aramco. A feel-good
ad using a woman's mellifluous voice, talking in cliches about the
future, etc. They don't mention its full name, Saudi Aramco, or that
its majority owner is Saudi Arabia. SA seems to have decided it wants
to improve its image, after the murder of Adnan Khashoggi and
allegations of war crimes in Yemen, and they seem to be starting with
Aramco.
 
Tunein has a practice of running the same commercial over and over and
over, several times an hour all day long. If one listens to broadcast
tv or radio, different programs have their own set of commericals, so
they change as the day goes on, and it's not annoying, but Tunein plays
the same ones all the time. And in many cases it plays the same one
several times an hour. The Aramco commercial runs 5 or 6 times an hour.
And it's part of a series of ads that take 3 or 4 minutes, maybe longer.
 
So in the car, I used to change to FM while waiting for the ads to end,
and then I'd forget and listen to FM for 10 or 20 minutes, and when I
went back to Tunein, it is almost always in the middle of another Aramco
commercial. Yesterday this happened 4 times in a row, one break and
then another 4 times.
 
So now I'm starting to wonder if it could be the same commercial, that
was on pause while I was listening to FM??? Or while the radio was off
altogether?? Is that possible? That the app knew the signal was not
beling played through the radio? Finally I've taken to turning down the
volume so I don't hear it. The app certainly doesn't know ablut that,
and it seems to work, or must it be my imagination?

The overload of commercials, coupled with the fact that every FM radio
station wants to try to recreate a Howard Stern Jr by having their
variant talk all morning (when they are not otherwise running
commercials) during the commute hours is why I now *only* play
pre-recorded, commercial free sound files from my phone over my car
radio. No commercials, ever, and no talking DJ's either.

This is not at all surprising. They cut to commercial breaks so
frequently that your probability of randomly switching back, and being
in the middle of a commercial break becomes quite high. You'll see the
same effect when channel jumping around on TV -- you more often than
not jump into a commercial break on channel X when switching away from
channel Y.
 
> So now I'm starting to wonder if it could be the same commercial,
> that was on pause while I was listening to FM???
 
Unlikely. It is much more probable that you were just unlucky and
picked the right delay time to return such that you were in the middle
of a commercial. If you were to time the content vs. commercials one
day you'd likely find you get a 2-3 minute commercial break every 4-5
minutes. It is not hard to end up returing during each of those 2-3
minute slots, given how often they likely occur.

Picked up a portable hard drive. Header ripped off flopping around. Can this be reattached, easily, by someone skilled in this sort of thing or is it a "big deal"? Otherwise, my portable harddrive aint so portable anymore.

Yes it is possible to repair this. The caution is that if the traces were also damaged, it may be tricky to reattach them. It is possible, but may take some time. I have done these in the past successfully.

Hard to be sure, but Siliconix was making PFET junction FET discretes with that
package, like this one

If that's your item, pin 4 is the case (just a shield, not diode-connected to anything).
There might be a S embossed on the can...
