I want to set up a simple, single function, remote control application. A cheap mobile phone, detect the ringing and operate a relay seems to be the quick answer. But I am concerned about wrong numbers so I need a phone that can be set to ring only on selected incoming numbers. Do any cheapo phones have that facility or is a luxury feature?

A lot of the nokias have a ring for selected groups feature. You could then put that number into the group. I think it should be on the cheaper ones. I would have thought you could create a java midlet app on any java enabled phone that would check the incoming number first if the feature wasn't available.

Doesn't a landline have a specific voltage change for ringing? That might be simpler. Just have to keep the number secret!

I've got a couple of older Nokias -marked inside as 1118 and 1600 both almost identical( 1118 has b/w screen ,1600 has colour) ,and about three years or a bit more -default date is 2005 -so there should be some around in second hand supply -you can set default ring tone in settings to "empty" ,and in the contacts menu assign a ( differing ) ring tone -( worked on the 1118) to over ride the default "empty=no tone) -So only rings on those numbers you assign a separate ring tone to .

RS do a mains switch, controlled over the phone, that requires an access code. We had it conected to a land line. I used it to to do system testing for years with no problems.

Thanks, but it has to be a mobile. There is no fixed line.

Thanks to jomo and botach. But my problem isn't in detecting the phone ringing - I am more than capable of designing a circuit to do that - but to prevent the phone from ringing except on certain numbers. I think botach's earlier post is quite helpful - those phones can be had quite cheaply on eBay

I think I have something dcb

Well, my work collegue actually, (I can't take the credit).

Ian, that''s his name, said he recently bought a mob for his wife; a Samsung 3050 for £25 on PAYG.

He says, and said he's positive, that the phone will not ring if the number is not in the phone book. He hasn't tried it but he saw that facility in the user guide. He said you can download the instruction manual for it, although I haven't done that yet.

Might be worth a look bud

Are you building a remote controlled IED dcb?

IF you can get hold of one of the older Nokias with a composer( 3310COMES TO MIND) in the ring tone section , you could make a "NULL" TONE - and make that the default ring tone .Then assign ring tone of choice to the wanted number .Does work - I used to do it on mine when on night shift -we had several thoughtless people at work who didn't work weekends and would phone you on say Saturday morning ,when you'd gotten to bed at about 6AM and were due out that night ,but phone had to be on in case of callout .Set up profile with Null as default - and assign ring to chosen number(s) .

That sounds better and cheaper than my idea Botach. I'd ignore my idea dcb and go with Botach's..

I've actually got that phone but it's of sentimental value; it's one I gave to my late brother and has texts he sent to me

Silly, I know, but I will probably keep it to the day I die and then it will be thrown away by someone anyway.

I've upset mysef now. Catch you tomorrow...

Just had a look at one of my older cheapos - It's got the null tone (no pun,Tone) on ,but it won't send it on -so if you get a 3310 - get another cheapo ,so you have a master source and a slave unit( if that makes sense)-the 3310 will forward the tone .Other alternative ,as I've saud is to check out other Nokias ( as someone else said) - you can designate numbers into caller groups .Any number not in a caller group falls by the wayside and phone stays silent .As for composing a null - sorry ,but I did it yew years ago ,when composing was the norm , but now -I'd be hard pushed to try .

I have a 3310 but I can't see how to make different ring-tones for different incoming numbers. Is it something to do with profiles? But how do you associate a profile with a number?

Thanks but I have already tried that. It tells me how to create and edit profiles but not how to use them. How do I associate a profile with a incoming number? (Yes I am very thick when it comes to consumer electronics)

Very suspicious I must say, it's certainly got my spidey-sense tingling, but then it would be a very inept terrorist who couldn't find mobile phone trigger instructions online! Don't go blowing anyone up dcb!

I think I’ve figured your initials out dcb you Deadly Camera Bomber. You're cover is blown

You don't associate a number with a profile -a profile determines the way a phone's basic functions work-as on your multi speed bike -the front cogs are the profile ,which you fine tune with other functions( on a bike one of the rar selection) ( in this case the ring tone associated with each number ,in phone book) .
Downloading this -http://nds1.nokia.com/phones/files/guides/3310_usersguide_en.pdf

Then "ASSIGNING A RING TONE TO A PHONE NUMBER" ( mENU 1-6).

My way to to create a profile(menu 12) with a name( e.g night) ,and assign it a default ring tone = my null ring tone(Also see tones,menu 5 p75) .Then in menu 1-6 , find a number in phone book and as per above ,assign it a different ring tone .BTW - on the profile menu -to change things use "personalise" .For a null tone - can't remember how I composed one ,but would start with a pause( rest ) . Composer is in menu 5 .It will let you play tune back .

Any clearer?


( AND - "Thanks but I have already tried that. It tells me how to create and edit profiles but not how to use them. How do I associate a profile with a incoming number? (Yes I am very thick when it comes to consumer electronics")
Don't be worried - I used to have a MSc customer( operated a successful computer sales company) with a phone system ,who couldn't transfer calls internally -despite my several attempts to teach him,his secretaries gave up ,and did it for him- they'd got it at first attempt) )
