Doorbell Issues

I have a problem with my doorbell, and it's driving me insane. A couple of weeks ago I decided to fix our doorbell, one that has not worked for a very long time (decades). I replaced the grommets that go on the tone bars. I cleaned the plungers and everything. It worked just fine, until about a week ago. Sometimes it will ring, sometimes it's very quiet, sometimes it doesn't ring at all, and sometimes it will do a short ring (the ring doesn't last very long, like it used to). Also, it is about 40 years old. Another thing, the switch is rated at 16V, and I'm using an 18V doorbell, could this cause the circuit to not complete properly? Here is a picture of it (cover removed) I thought by putting hot glue on the grommets would help, but it didn't. The pic shows the glue, but now it is removed.

Circuit help

So, my brother tasked me with making him a customizable doorbell for his house for Christmas (of course he didn't tell me till last week, but whatever). looked around at a bunch of stuff online and found a few decent items. some of them use those voice recorder modules from radio shack...which  might work, but I've used them before and they're pretty quiet. also, not the best sound in general from the mic used to record to them. so I found this thing;=1 which is a riff on this thing  which uses an ATTINY85 to play audio via the PWM output from an SD card. I like this guy because it's gives more options for sound and is generally more "gee whiz". however, the guy built it from scrap parts and has some admitted flaws in it, notably the power supply and the audio amplifier. so, I'd like some help figuring out how to build the same thing, but with a more "correct" power supply and amplifier. also, not exactly an electronics wizard so the fact that there are a billion different chips listed as ATTINY85, I wouldn't mind if someone can make a more sensible parts list (there aren't that many parts). I plan to trigger the thing with an off the shelf wireless doorbell type thing.

Doorbell- bypass jumper? Help!

Hi all, I have a wireless Heath/Zenith doorbell. It has a wireless button (battery) and plug in doorbell chime. It is model SL-6166, very common design. It works fine with the wireless button, but I am working on a different project, and need to figure out how to "manually" use a jumper wire on the circuit board of the chime itself to make it go off. I need to know how to trigger this chime with a jumper so that I can connect 2 wires to the chime from one of my home automation devices (an I/O Linc) so that the home automation can trigger the chime by sending a "closed" or jumper the two points on the chime, to make it go off. For this project, I can't use the wireless doorbell button to trigger the chime. There is a good picture of this board at: That is someone else's post with a different question, but it is the exact unit I am trying to figure out. I don't have enough technical knowledge to know where to jump this circuit board to make this door chime go off manually. I hope one of you can please help me do this? Thanks in advance!

Boy inventor re-imagines doorbell, gets VERY rich!

A 13-year-old boy from Croydon is set to make hundreds of thousands of pounds after inventing a doorbell that calls the householder if no-one answers the door. The boy entered a school "Dragons' Den" type contest, and ended up with his idea in production.  Orders made so far should earn him £250,000 ($411,000).  Three of his fellow contestants ended up with full patents on their ideas, and one other is negotiating with a Chinese manufacturer to get his idea on the shelves.  That boy is only twelve! Dubbed Smart Bell, the device came about in response to a competition hosted by Rook's London school. The contest, however, necessitated a working prototype. Rook's parents passed the plans along to a family friend, Paula Ward (crowned world's top female inventor of 2004 at INPEX), who sent the plans to China. Less than a year after its development, major U.K. retailers have signed up to sell the Smart Bell, which will retail for £40, or about $66. The Smart Bell has a built-in SIM card and other cellular technology that will call the owner's phone. The unit also produces some subtle white noise that mimics the effect of an intercom.

Any suggestions on creating a "doorbell" for my cat to use?

My cat comes to our (glass) sliding door or window several times a day and either sits outside and waits or scratches on the glass to be let in. For the most part, we see him at the door/window or hear him banging on the door, but sometimes he waits out in the cold. I thought it might be cool to design a "doorbell" he can use so that even if we're in another part of the house, we can still hear when he needs to come in. Right now, I'm thinking something that will register his weight, either outside the window or the door (he usually goes to the door first and then the window if no one comes right away), and that will ring a bell -- maybe a regular doorbell set-up, just messing with how the "button" is pushed? It would be cool to design a little button/pad that he actually has to press (he's smart; he can figure it out), but placing something where he likes to stand/sit would probably work just as well. Right now I'm going to start by looking into how doorbells work, and then whether I need to make a weight-sensing device or if I can jerry-rig an actual doorbell to respond to some kind of pad for him to sit on. I don't know how much doorbell's cost, but I'm assuming they're pretty cheap. I could probably pick one (or two, if I need to do multiple trials) up at my local hardware store, but if anyone knows of online suppliers who provide free samples of doorbells or doorbell-like devices, or things that I could use for my pad, that would be nice. I think my main qualifications for the pad/button are that it be easy for him to sit on/push, sensitive enough to read his weight (probably 10 pounds), and sturdy and weatherproof, since it will be outdoors in all seasons.

Home automation: doorbell analog door phone intercom?

Answer doorbell with home phone: I would like to create a setup in which a visitor rings the front doorbell that rings our home phones.  When we answer a phone it will act as an intercom so we can communicate with the people outside the front door.  There is no doorbell system in place so I am essentially starting from scratch.  I'd prefer doing this in an "analog" fashion since we are in a rural environment with unreliable power and no cell reception.   Basically, I want to know if there's an easy/affordable DIY alternative to the several hundred dollar door phone systems I see available for sale. I would also like to install a remote electric door strike so I can lock/unlock the front door via our landline. New phone shopping: I need to buy a new home phone system anyway, since my mom only uses the speakerphone on the handsets and callers complain they can't hear her well.  Features I'd like: --Power back-up operation (handsets work even in a power-outage) --"Eco-Mode" where it consumes less power when you use it closer to the base --Excellent speakerphone on handset --Long battery life out of charger --Lightweight, easy to hold/grip handsets with large easy to press buttons and clear display There's several Panasonic models I've looked at that seem to fit the bill.  I'll admit I was initially tempted by the new Vtech video doorbell phone, but there's many characteristics about the actual phone/handsets that would make it difficult to use. I wondered if getting a Bluetooth-enabled phone would be advantageous if a handsfree calling device could be connected, just like in the car but for the home phone.  But I don't know how to do that, if it's possible. Just thought I'd mention the new phone shopping in case someone has any advice on best selections based on current home automation desires.

Hi all. Hoping I can get some suggestions. I have a water alarm in my basement, when it's sensor gets wet, it beeps. This does me no good since I can't hear it. What I'd like to do, it hack it so that instead of beeping, it lights a led I can hide somewhere in the house. Maybe in one of the wifes stupid knick knacks in the living room. If I just needed to wire the led to the beeper, I could figure that out. But I want it wireless. Any suggestions? Mechanically, I'm good. I know how to assemble, disassemble, solder, etc, but I don't know much about the electronics involved. I'm thinking I can use an inexpensive wireless doorbell as my transmitter and receiver. So, I guess what I need to do, is figure out how to incorporate the doorbell button into the alarm so when the alarm triggers, it activates the doorbell. Then, install an led in place of the chime and hide the whole shebang in something. (If it could also send me a text, that would rule, but it's way outside of my current skill level.) Will it work? How do I do it?

Create door opening wireless notifier? Reed switches? Answered

Hi, I have a Vellerman K8055 USB experimental board that I have hooked up to one of my machines. Yesterday, I took our wireless doorbell apart and with a multimeter found the signal that sparks the 'ding-dong' sound when the remote bell is pressed. I wired that into the K8055 and then to cut a long story short, when the bell is pressed, it pops up on my TV and tells me that someone has pressed the bell (using MythTVOSD multicast if anyone is interested). A link to the card:⟨=en&id;=351346 What I'd like to do is to extend this mechanism to my doors. When a door is opened in the house, then I need a signal to be sent to a receiver device also wired into the K8055 so that I can capture that event in my program. I have thought about using magnetic reed switches on each door with hacked wireless doorbells (around 3-5 GBP on ebay from China). One problem I have is that I can only find 'normally open' reed switches, meaning that when the door is closed so will the reed switch contacts - this in turn means that I will be constantly notified (should I be able to make this work) that the door is closed. If I could find 'normally closed' reed switches, I could have one of each on each door, What is the cheapest/most elegant solution to this problem? Is using hacked wireless doorbells the way to go, or is there a better way. I'm a relative novice with electronics - I'm a dot net developer by day with experience of data capture cards, and have toyed with the Arduino, Lm386s, 555s, 4017s etc... some with instructions from this site, so whilst not a complete beginner, I am what I would call, "an enthusiastic amateur'.

Wireless, Wireless, WIRELESS! Help with circuits

Heyall, I just have a seemingly easy problem, but apparently it's not. Everything out there is wireless, doorbells, your electric car key, the fan control, garages, my bike speedometer. With so many wireless circuits, why is it so difficult to find a cheap, inexpensive circuit that a hobbyist can make? No, I didn't mean buy a circuit then mod it. I've searched all over and it's so hard to find a simple wireless solution that includes both a RX and a TX. I've seen Xbee but that's something I would have to use with my Arduino. It's also not exactly 'cheap'. So that get's crossed off the list. Are there any schematics for simple wireless RX/TX button or two that works up to 50 feet? What about schematics for a wireless circuit that works up to 100 feet? For my RC plane I have this TINY receiver that has six channels. The transmitter isn't that big either and it works up to 1 mile! But instead of paying 25 bucks for 1 mile and 6 channels, what about 1 or 2 channels for a 10 dollar circuit? See what I'm jabbing at? I don't want to by a doorbell then start unsoldering stuff from board to mod it! With so many wireless applications out there this should be a walk in the park! If you can give help me I would GREATLY appreciate that! Thanks!

(HELP) Linking Wireless Pir Sensor To Wireless Chime

Hi, I'm trying to use a wireless PIR sensor to activate a wireless MP3 door bell for an art project I'm doing so that when people walk by a particular spot, sound I've uploaded to the doorbell chime will play.  It has to be wireless i'm afraid... If anyone is bored this Sunday afternoon and feels like helping me out I'd be very grateful as I need this to be operational by Tuesday and i'm no electronics expert. To say thanks I'd definitely paypal you some beer money!

Since then I've been reading a lot about DIP switches that was previously unknown to my technically ignorant mind. So, I've taken a pic of the guts in the PIR and I guess the frequency ID is determined by the pins on the top left that read A0-A7? and the wireless doorbell has 6 DIP switches in the battery compartment like so: as well as the door bell button (also wireless). Is it possible to get these to work together, and if so, how would I do this with a minimum of hassle that someone with little electronics expertise like myself can understand? A very large thanks to anyone who can help my befuddled mind get around this!

The first is a device that would sit under coffee air pots.  There have been countless times when I've gone to get coffee at a self-serve place and there are five pots, but no one tells the counter person they are running dry and I then I have to wait for them to brew.  A pressure plate under the pots would control set of red/yellow/green LEDs to indicate how full the pots are. The second is to use a pressure plate outside the door where your pet comes in and out of the house.  It would trigger a doorbell when your pet wants in before it gets a chance to start scratching up the woodwork.
