Key Kip, The schematic is ok in the instructable but wrong in your video on youtube! Cheers!

AWSOMEEEEE!
could this wake a PC?

[sk8r4life]

few things 1. where did you get the audio receiver and transmitter and how much? 2. would a burglar really ring a door bell?

[georion]

yes and no--its a check to see IF someone might be home--we dont like surprises,niether do burglurs

[Kipkay]

Links on the Instructable for all of the parts. This is a common practice to impersonate a survey taker, sales person, etc...ring the doorbel. If no one answers maybe check the house out.

I'm sure you would know, after all, you did open that window in no time flat ;P

[ElvenChild]

but a smart burglar would hear the audio repeating in a loop and think that is one weird dog!

[ARJOON]

however you need to let your pc on. it will eat up too much electricity.hell yeah i know kipkay. he is just an animator, not smart at all 

[Kasm279]

The only thing you would use the PC for is to record to the recording module. Other than that it has nothing to do with the operation.

hello! , would that circuit work like to power a relay so that i can turn a motor while the doorbell button is pressed? im trying to make a sistem to open my door as i press the doorbell button for my room thanks.

Hey kipkay, You might want to reject all of your patches, they make your orangeboard not work.

[Bartboy]

lol, and that's a bad thing? Does he really want MORE comments?

[Berkin]

Ingenious! Keep up the great work!

[Mr. Squishy]

That will scare a burglar away for sure.

[Squid Tamer]

Neighbors who visit often will start to wonder why they've never actually seen the dog! (Could end in people looking around and under furniture when they think you're not looking, or in a call from PETA about confining animals! ;) )

Step 6??

[jimmytvf]

i guess that's a mistake of Kip, he is human too

[mhkabir]

Or is it a bug in instructables??

[Nabil]

Hi, i have a question: If u press the doorbell a couple of times quickly, will the dog barking sound react weird?.

[jimmytvf]

i don't usually ring doors this way... (if are my close family as my aunt, i ring this way, because they now that's me)

[imshanedulong]

Clever!! You should get a lower pitch bark to make it scarier!

[haloalternative]

Reminds me of Ferris Bueller's Day Off.

[TheCheese9921]

Haha that is exactly what I was thinking, great movie

[RobbGodshaw]

This was in an episode of Weeds. Cool instructible.

[JasperCat]

My neighbour has a store bought version of this its not very convincing. Makes me smile when it begins to run out of battery and sounds odd though :)

[hunnynspice]

awesome!!

[Goodhart]

Recording suggestion: incorporate the sound of the doorbell first, and THEN the dog barking. It may sound more realistic to have it sound as if the doorbell is still working (sounding as though the sound of the bell made the dog bark).

[Kipkay]

The doorbell will still ring as normal.

[Goodhart]

Ah, ok, on a quick read, I missed that, sorry

[D.L.H.]

Awesomeness!!

[Strawbale Shop]

Very cool!

[Zaphod Beeblebrox]
