Forgot your apartment keys? If you’ve got a ritzy building with a doorman, no problem. If your digs are a little more modest, you might only have an intercom panel that calls up to your apartment so someone can buzz you in. But if nobody is home, you’re out of luck. That’s why [Paweł] spent an hour whipping up an intercom connected automation system pack full of goodies.
The design is pretty simple – an ATMega328P to snoop on the analog phone ringer in the apartment when the intercom call button is pushed, and a relay wired in parallel with the door switch to buzz him in. For added security, the microcontroller detects the pattern of button presses and prevents unwanted guests from accessing the lobby. Things got really fun when [Paweł] added a PCM audio module to play random audio clips through the intercom. As you can see in the video below, an incorrect code might result in a barking dog or a verbal put-down. But [Paweł] earns extra points for including the Super Mario Bros sound clip and for the mashup of the “Imperial March” with “The Girl from Ipanema”.
True, we’ve seen a slightly more polished but less [Mario] version of this project before, but the presentation of this particular hack has us grinning from ear to ear.

[Ken Kawamoto] turned the rather bland view from his livingroom into that of some high-priced real estate. It only works at night, which is going to seem odd since the image above shows a daytime scene. But it’s still a pretty sweet concept.
The video below shows the actual view from his window. We don’t think it’s all that bad (we once lived in a ground-level apartment looking out on a parking lot… yuck!). But the view of the Abbey of St. Étienne in Caen, France seen above is much better. He simply put a projector on his balcony and closed the light-colored blinds. So far he has to bring it in after each use, but we see this as more of a thing to use only when entertaining anyway.
We’ve seen a few other attempts over the years at hacking your view. Here’s one that adds fake windows using LCD screens. The thing that makes that one work is the ability of the system to track the viewer and change the perspective accordingly.

College students have returned in droves to dorms and apartments at campuses everywhere. So this is the time of year we usually start seeing some coded entry hacks. [Charmonkey] recently took on the challenge at his new apartment. There were some caveats though. He needed to ensure the Landlord could still enter using a key, and he didn’t want to alter the door or the jamb in any way. What he came up with is a coded entry system that can turn the deadbolt.
In order to mount some hardware on the door he removed the inner part of the dead bolt assembly and used the pair of threaded tubes on the adjoining lock section as anchor points. This holds the Pokemon tin he’s using as a project box securely in place. The rest of the components all mount to it. These include the stepper motor that actuates the deadbolt, a switch for manual operation, an Arduino, and a motor driver board.
He got really creative with the keypad. The wires connecting it travel through the door’s peephole and into the smaller plastic project box that hosts the rest of the hardware.
Here [Matthew Br] explains the situation he’s in with the neighbors that share this wall of his apartment. When they listen to music they like it loud and so he gets to ‘enjoy’ the experience as well. But he can’t ignore it any longer, and has decided to use a sound volume detector to blast some tunes right back at them.
He taped a microphone to the wall and wired it up to his Arduino. It monitors incoming sound and, using an adjustable threshold, it will trigger when the neighbors are too loud. We think he was wise to include some time filtering that makes sure the loud noises are sustained and not just the result of someone bumping into the wall. When the system does detect loud music for a sustained period it triggers [Matthew’s] own CD player to pump out Who Let the Dogs Out? by the Baha Boys. It will play for a period of time, then shut off to listen and see if the neighbors are still rowdy.
He documents an actual run in the latter half of the clip after the break. We sure hope he’s living in a building with just two units, otherwise this will drive the rest of the neighbors batty as well!
