Now here’s a really cool home hack. [Luis Rodrigues] has automated his garage door to open, simply by flashing his headlights at it.

But wait, doesn’t that mean anyone could break into his house? Nope. At first we thought he had just added some photo-sensors and a bit of computer logic in order to turn a pattern of lights into an output to open the garage, but no, it’s actually specific to his car only. Which is awesome because if anyone ever tried to copy him to break in, all they break into is a very confused state of mind.

You see how it actually works is the headlight output is connected to a control box under the hood of his car. A Moteino (RF Arduino variant) reads the input signal of the headlights flashing three times, and then communicates wirelessly to the garage door in order to open it.

But [Luis] also has a gate outside his property — so if you hold the lights on for a second, both the garage door and the external gate will open as well.

Pretty awesome — mind you, is a garage door button really that much harder to use? This is definitely safer if someone steals your car and happens to have your address though!

Adventures in Moteino: Remote temperature monitor

Colin over at CuPID Controls writes:

We want to put our remote sense and control modules out into the wild and read and aggregate them as it makes sense.
Our basic system layout is as below. We’ve got multiple wireless nodes that broadcast data periodically, and a controller/aggregator that will log this data, acknowledge receipt, and do something useful with it. Eventually, we may have intermediate powered nodes that serve to mesh the grid out, but for now, our nodes just send data to the controller.
We’re currently using these awesome little RF units, called Moteinos. They are an Arduino clone that can use the standard IDE with their bootloader. They’ve got the ever-so-popular ATMega328P chip that is familiar to anybody working with an Arduino Nano or Uno.

Adventures in Moteino: Remote temperature monitor - [Link]

mote

One of the apparent unofficial themes of The Hackaday Prize is the Internet of Things and home automation. While there were plenty of projects that looked at new and interesting ways to turn on a light switch from the Internet, very few took a good, hard look at the hardware required to do that. [Felix]‘s Moteino is one of those projects.

The Moteino is based on the Arduino, and adds a low-cost radio module to talk to the rest of the world. The module is the HopeRF RFM12B or RFM69. Both of these radios operate in the ISM band at 434, 868, or 915 MHz. Being pretty much the same as an Arduino with a radio module strapped to the back, programming is easy and it should be able to do anything that has been done with an ATMega328.

[Felix] has been offering the Moteino for a while now, and already there are a few great projects using this platform. In fact, a few other Hackaday Prize entries incorporated a Moteino into their design; Plant Friends used it in a sensor node, and this project is using it for texting and remote control with a cell phone.

Open Source SwitchMote Promises Easy Home Automation

moteino

[Felix Rusu] is fast becoming a big name in home automation with his clever Moteino systems. His latest is called the SwitchMote which is a super easy way to upgrade your light switches for home automation, and he’s just released the source!

The SwitchMote is a drop in wireless light switch which lets you control a standard AC load, limited to 100W at this time. It uses a solid state relay (SSR) to perform the switching, but like any project involving mains electricity… MAKE SURE YOU KNOW WHAT YOU’RE DOING!

It makes use of a Moteino (duh) which is a wireless Arduino clone that operates over RF. We’ve seen it used before to control a Keurig coffee maker, operate a garage door over the internet, and even text you when your sump pump fails and your basement is about to flood!

Excited? Take a look at his GitHub repository, and check out how it works in the following video.

Did we mention you can program it wirelessly as well?

Mailbox notifier texts when the letter carrier arrives

mailbox-notifier

[Felix Rusu's] mailbox is on the other side of the street and he’s got a pretty big front yard. This means checking for mail is not just a pop your head out of the door type of activity. This becomes especially noticeable during the winter months when he has to bundle up and trudge through the snow to see if his letter carrier has been there yet. But he’s made pointless trips a thing of the past by building a notifier that monitors the mailbox for him.

He’s using a Moteino, which is an Arduino clone of his own making. It’s tiny and features an RF module on the underside of the board which takes care of communicating with a base station inside the house. The module seen above rolls the microcontroller board up along with a 9V battery and a hall effect sensor which can tell if the mailbox door is open or closed. When the Arduino detects a change to that sensor it pushes some data back to the base station which then relays the info to a computer or Raspberry Pi in order to send him a text message. All of this is shown off in the video after the break.
