Halloween is a great time for makers, we get to make all kinds of cool costumes and spooky things. Sometimes we get to play with fire. Well at least Chris Lee does. This flaming pumpkin is enough to keep them pesky kids from toilet-papering your house, or catching it on fire after they do.
The pumpkin is triggered by an Android phone, talking to a RFU-328 radio and Arduino. The Arduino triggers 2 relays, 1 to activate a furnace igniter, the other activates a solenoid that releases the flow of gas. The spray mechanism comes from an AirWick room spray and is filled with butane.
Chris made a comment about maybe converting this to shoot silly string out during actual Halloween, either way it’s a cool project.

Mico is an Arduino shield that talks to your cell phone. Literally. It connects via the audio jack on your cell phone, and has the ability to read DTMF tones for control. It also can answer the phone by using the same technique your old wired headset does.
Some of the applications the mico guys have put together are it answering the phone and reading out sensor data. It has a audio playback library so with some crafty recordings you can do cool things. They even have a demo application of the shield talking to Siri on IOS in order to do more functions like send text messages.
Interesting concept, I think it’s still missing something like a little more control but I give them props for being different.
The project currently has a kickstarter going to launch a large production run, there’s also source over at github.

[su_quote]… it runs over AVRs microcontrollers and include all the libraries and drivers required for a complete a distributed intelligent network, it also includes an Android user interface.[/su_quote]Ever wanted to make your home smarter ? Or just remotely control basically everything in your home ? Souliss is here to help. It’s a framework for DIY home automation.
What I like about Souliss versus having used traditional home automation hardware (like Z-Wave) is you aren’t restricted to what modules are available. You can craft your own using a lot of familiar hardware like Arduino’s (and I’m sure Raspberry Pi’s in the future). It’s not restricted to specific methods of communication either, you can do wired or wireless or wi-fi or serial or whatever you can use to get your devices to communicate. Great project!

You have probably seen those little dongles that let people swipe their credit card on their smart phone or tablet. These little dongles transmit data to the device via the microphone jack. The audio recorded is then examined and the data is either a one or a zero.
In the example described by the article, they are using a PIC and the data is encoded via manchester encoding. A resistor and a pot are used to tweak the output level. This is a great way to send data to a smart phone or tablet without making any crazy custom dongles but you are limited in capabilities.
Schematic and example source code is included in the post.

What I find really funny about new hardware coming out is people generally do three things first. First they try to root or jailbreak it. Second they try to put Linux on it. And the very next thing they do is port emulators to it. Following in succession here’s a Gameboy emulator running on the Google ChromeCast.
