OK, I need a device that will indicate that the newspaper has arrived, and is sitting in the tube next to the mail box.

Walking out every morning to get the paper, never know it is there until I dredge through the ice, snow, and mud is getting old.

Going out more than once because it is late is getting even more frustrating.

I don't mind during the spring and summer, probably the only exercise I get.

Is there such a thing? Or could one be made?

All it needs is a limit switch to be activated by the paper sitting on it.

The switch would need to activate some sort of RF device, with a matching transmitter inside, say with a green light, that would be on once the outdoor unit was triggered.

Kiss? Strat?

Either of you know this technology.

Any ideas?

Either of us... LOL. Yes, we have 500 heads. If you find out please patent it as I am sure, tkrussel a device such a thiss would be in high demand. Although I don't have to look for my paper, my 'paperman' tosses it all the way up my driveway and hits my door and it lands on my porch. I don't know how he does, he must be about 80 !

Only downside is when this happens it is 5 am and the dog starts barking ! That's how I now my Toronto Star is here in rural Ontario.

You are lucky you have a tube and it gest inserted. My delivery person just tosses it on the driveway. I'm luccky if he double bags it on wet days.

Do you really something that flashes in the house? Wouldn't a light on the pole or back of the tube do the job?

There are any number of ways you could trip a circuit by inserting the paper into the tube. Then just activate a bulb mounted to the pole.

A neighbor of mine(growing up)was an inventor,he designed and produced an automatic 'mail-is-here' mailbox,it automatically showed him when the mail was in the box.

If that could be done(and patented) anything can.

Tell you what,you design it,I'll patent it,and we'll make Ask Me the sponsors,heck we could even advertise in here for it!

Yeah,like that's going to float... :p

Hey get the newspaper person to deliver it with an RFID tag like the ones they use in the stores.

OK, the stupid suggestion is out, Can you post a pic of your mailbox? There are "mail has arrived" wireless devices out there.

I have too much going on right now, so in case I need a break and need something to do before going to bed, I'll think about it.

There is no power at the mailbox, right?

Loox at the X-10 website. They have countless devices which are wireless that may fit your application. Smarthome is another supplier which may have what you need, but you may have to do some modifications.

Huh, that's pretty slick for a mailbox. It appears to need to move to activate. The problem I'd have though is every newspaper box I've seen has an open front with no door. Maybe if you modified it to use a motion detector mounted in the box?

Or just go low tech and rig a mechanical solution. I read about a guy that just used a block of wood attached to a dowel that would get pushed out of a hole in the back of the box when the paper was inserted. Paint the dowel some easily visible color and you are all set. Then again, low tech isn't as much fun.

Dec 11, 2008, 12:50 AM
Yea, low tech is cool too. The second link using the window sensor is really close to what tk envisioned.

I'm thinking of a more complex sensor made from an array of tactile switches such as these.

SWT6-V7K (http://mouser.com/Search/ProductDetail.aspx?qs=1qzrMKUcZ2hsY5Phu1dn4Q%3d%3d )

The idea would be that it would not take up much height and a small piece of say copper clad PC board material (to give rigidity) Say a PCB sandwich with enough switches to support the weight. You might need a few locator pins.

You can get a bit that will remove some copper clad, so you can use a double sided board as the sensor. The top being one side of the switch and the bottom the other.
In one case you would remove some on the bottom and solder the top and vice versa.

This "SENSOR" would be very thin. The top can have a bondable teflon sheet epoxied to it. Put just a little forward facing slope to it to allow it to drain.

Sensor would not be cheap.

Here is the particulrs/manual for the Houselink receiver:

Looks like the microswich/sensor idea would work.

I might be a little late on this one, but there's a motion sensor that you can buy, and various lights, alarms and whatnot, at Menards. I'm sure they have them other places too. I'm really sorry I don't remember the brand name but there were all sorts of pieces that you could buy. The one in particular that I'm thinking of is a piece that plugs into the wall and you can plug something into it, a radio, a lamp, anything really. And when motion is detected (where ever you place the sensor- the sensor is also heat sensitive so it will go off for people, animals, etc. not for leaves or falling branches) whatever you have plugged into the outlet will turn on. All of the pieces are remote so there's no wiring involved. It was really a cool idea. If I remember the brand name I'll get back on here and let you know.

Wireless command. That's the brand. I'm betting all you would need is a wireless sensor and something that would plug into an outlet and you'd be set.

Hi ZoeMarie, our neighbour who hates our dog put in camera sensor that makes a high pitched sound when she barks. The only thing wrong is, he put it in at the front corner of his house where she isn't. We didn't know what it was when we heard this clicking sound and thought it was some kind of surveillance equipment that this nutcase had set up, so called the police. Who went over and found out it was for dog barking. It is irritating to say the least !

The clicking? Or the dog barking? The motion sensor doesn't make any noise. And like I said you could plug anything into that outlet. A lamp would be good, doesn't make any noise, just turns on.

I have the motion sensor thing that I got at Lowe's. It's exactly like you said. A wireless motion sensor and a module that plugs into an outlet.

It has a chime mode or different times that the outlet can be live for.

I mount it indoors for my elderly mom to turn on a small nightlight when you walk in the living room. Once you sit down and it times out, it's off because your not facing it.

It is designed for a light, so there is a photo-cell that won't turn it on in bright light.

If not mounted high, it might just "dissapear" frequently.

The sensor that's constantly on creates a battery drain on the transmitter, possibly depending on how it's designed.

If the events transmitted are switch open or switch closed then your OK, but if there is a continuous transmit for an event, then it sucks the juice out of the transmitter battery.

ZoeMarie it isn't a motion sensor. It is some kind of sensor to deter a barking dog. Didn't you get that out of my post ? It doesn't work, it doesn't stop her barking. I wasn't posting about your sensor.

I am thinking of a prebuilt wirless "Driveway Alert System" mounted to the side of your paper box. I think it would work perfectly.

Otherwise, my mind starts traveling to proximetry switches and the price tag starts getting too high too be feasible.

KISS

Driveway alert typically detects metal objects.

The Houselink system might require a little bit of "glue logic", so that the continuous press causes a brief pulse and a little bit of reverse engineering the Keyfob.

Another possible sensor is a sliding plate with a spring with a little bit of tension.

In the OFF position, the plate in the rear is extended. Might be 4-5 inches. It's mounted on 4 linear bearings.
It has very slight tension, such that with no paper it falls to a rest position.. With a paper, it pushes the plate back and the friction of the paper holds it toward the rear. Meanwhile there is a microswitch or alarm switch at the front of the plate.

Let's say you use the mailbox system. If a swirch works your fine, suppose it doesn't.

I think you can drill a large hole in the back plate and put a hinged door on the back. On that door mount the mailbox sensor. Have it so it's magnetically held in place and when you push it away, the hinge drops. To reset the hinge you put your fingers into the 2-3" hole and push the plate back up.

A couple of good ideas listed.
How far from the house to mail box, and is their electricity near mailbox.
I love the Linear transmitters and receivers.
I use a door/window transmitter on my van, when a door is opened, I am sleeping, it chimes the alarm tone on my keypads, the DSC panel has a keypad that can provide 4 different sounds for 4 different locations.
Also on boats, I use a Float switch higher than bilge pump float switch, so if battery, pump, or float switch fail, and water rises to 2nd switch which is connected to a DSC(can use other manufacturers or a Linear)door/window transmitter to transmit to receiver, add a AVD dialer, and it will call you and 7 others(anywhere in the world reachable by phone).
Plus you have 3 unused inputs for other things, 1 could be a contact from Time Clock, so everday at 3:00, the dialer would call you, also allow to listen in, and by pressing 2, you can have 2 way conversation(less than $150)
Could be handy to see the kids are OK, quit playing the video games, and get back to their homework. I know you would like it to latch so if visual or audible is not in ear or eyeshot, you will know of the event happened.
Also is the mailbox in view of front door?
There is also a set of photobeams that are the size of a regular sized LED(less than 1/4").
Let me give it some more thought, Take Care

Wow, thanks everyone for all the responses.

I have not had time to look all over, getting super busy at work again.

Feast or famine in my business. Got to grab the business while I can.

But Duh, mail box alarm. Go figure. I pride myself as a expert at searching the internet, AKA Googling, something about that word bothers me. OCD I guess.

But half the battle is to know what words to search for. Tried searching for Newspaper alarm, get some weird hits. I gave up after three pages. Went blank after that and reached out here where great advice and answers are the standard.

Eh um, little pat on self's back, thank you, no applause, just throw money.

OK looks like I definitely got some directions to go in, and some homework to do.

Thanks everyone and

Merry Christmas (yes even from a devout atheist, but still old fashioned)

And Happy Holidays!

I'm the expert googler. I've been told that. You can't have that title.

Stratmando did mention Linear. I was going too.

I do think that you may have to create a momentary contact from a maintained one at low power to preserve battery life unless we can come up with a "jiggle sensor".

SmallParts.com: The Hardware Store for Researchers and Developers (http://www.smallparts.com) is an excellent resource and so is Stock Drive Products.

Moisture, corrosion and the proverbial "5 finger discount" has to be considered. In any case you have a place to start.

You gave me an idea for a project that I don't have time for too, but would be worthwhile. A wireless separate refrigerator and separate freezer in the same room in the basement door prop alarm and a water alarm.

Thanks for the ideas.

Happy Holidays!

I was thinking about adding a chip such as this one http://www.st.com/stonline/products/literature/ds/2050/hcf4047.pdf to make a pulse out of a contact closure. Actually you would have to add a schmidt trigger as well and reverse engineer the circuitry just after the push button.

With 24 V power and 7 mA power consumption, not likey to work with a battery powered transmitter. Besides it pulses on both the rising and falling edges.

Hence the question of Power near mail box.
As far as triggering on opening and closing, He would be better off resetting the latch condition AFTER retreiving mail.
TK, does your mailbox have a door, or is it the open tube?

Opened, also has several weep slots inside bottom.

No chance of power, anything would need replaceable rechargeable battery that could hold up to Maine winter.

I will go through all the ideas offered.In my mind, the remote unit could have a micro-limit switch on the bottom, as part of a RF transmitter sending a signal to a base unit inside.
