Improvising handset beep?

  1. This is about communications between house and shed/workshop.
    Important stuff, like being called in for dinner. For some years I've
    had a one-way gadget that sounds a tone in the shed when either a
    certain light switch in the house or the front doorbell is pressed.
    But I'd like to be able to *acknowledge* that, by pressing a button
    which would sound a tone in the house.

    To avoid the hassle of wiring or more expensive solutions, I thought
    I'd simply utilise the Paging function on the downstairs cordless
    phone, a Samsung SP-R5100. But I'd forgotten how ancient it is.
    Handsets are no longer available, even at DigiUK who sell some old
    stuff. And none on ebay UK.

    Under 'Intercom Between Handsets' in the user guide, not surprisingly
    I read "This feature is available only when you have more than one
    handset." But I wonder how hard it would be to rig up something
    primitive? Any radio/wireless/mobile experts here able to offer any
    suggestions please?

    Or, by some fluke, anyone in UK reading this who has a spare handset
    gathering dust...?

    If you have mains supply to the workshop why not a simple plug into the
    mains intercom at either end. I've probably a set of 2 or 3 somewhere.
  3. Yep, thanks, reasonable solution, and I may end up with that. Has the
    advantage of speech! (Hmm - for shed communications, maybe that's a
    disadvantage?) But ideally I'd like to avoid finding room to stand or
    mount the units, and minimise expense. At present my gadget occupies
    zero extra space in house, and in shed one small case mounted up in
    ceiling corner, with my simple receiving circuit. (Power supply from
    one of the several already in place.) Quick look beforehand at Maplin
    found a pair at about £32UKP, inc VAT and delivery. What price are

    That's an interesting stock you have! You're not by any chance the
    same guy I used to buy bits and pieces from somewhere in South London
    about 25 years ago are you? I recall there was room in there for just
    him and one customer at a time. Rest of space occupied by Stuff <g>.

    I'll try and find them first , the problem is there may be 3 units rather
    than 2 but 12 squid plus p&p if 3 units, 9 squid if 2

    Just use the same wires, and add a speaker in the house, and a button
    in the shed, such that when either button is pressed, both speakers
    sound. :)

    If you only have two wires, this could be an interesting project
    indeed! ;-)

    Good Luck!

    One of the companies that advertises kits was selling a kit in which each
    station contains a small amplifier and uses a variant of power line
    signalling in which pressing the send button on one station applies power
    through the signal line to the receive station, the company has a PDF
    schematic for download so its worth googling electronic kits and see if it
    turns up!

    Wireless doorbells?

    FRS handheld radios? Or is that frequency band allowed for public
    use in the UK?

    How about a pair of these?

  8. Thanks. Let me know if you put your hands on them, and you'll have my
    order pronto.

    Hi Terry...

    Being called in for dinner? You mean sending in your request for
    another cold one, don't you? :) :)

    If there happens to be a few extra dollars (pounds) available,
    why not buy yourself one of those two or even three handset
    cordless phone sets?

    Telephone answering and placing outgoing in your shed; they allow
    inter-handset conversations, call transferring, etc. Fantastic.
    Great at the lake - the main base in the cottage, another handset
    in the garage/workshop, and the third in the boathouse/dock area.

    Don't know what might be available to you over across the pond
    (I'm in one of the colonies :) but Panasonic makes a great one if
    you can find it.

    Take care.

  10. Thanks Ken. That's why my first choice would have been to simply buy
    an extra handset. But there's nothing wrong with the single-handset
    Samsung, so not keen to dump it.

    Anyway, early tests indicate that the dock to heli-pad range might be
    an issue <g>.
  11. Why not just use a simple and cheap wireless doorbell?

    Dave :)
  12. Thanks Dave. I do already use adapted versions of those in a few R/C
    gadgets, but range is an issue. Although house to shed/workshop is
    well within the claimed range, the various walls (including the
    intervening garage) plus possibly the many sources of interference in
    my workshop make reception unreliable.

    Any cordless phone with intercom feature would work...doesn't even have
    to be hooked up to the phone line (although infinitely more useful if
    so). They click 'intercom' in the house, handset beeps, you push a
    button and say 'Right-o'.

    I pick these up at second-hand stores and yard (to you teabaggers, I
    believe that would be 'boot') sales for a couple of dollars. Usually a
    good cleaning and new battery pack puts them in order...sometimes have
    to cobble up a new power supply from my extensive stock of wall warts.
