Hack a Day
Here’s a pretty tricky piece of consumer electronics reverse engineering. [Joe Fitz] came across the Nikon WU-1a. It’s a dongle that plugs into a Nikon D3200 camera, producing a WiFi connection which can be picked up and controlled from a smart phone. The app shows you the current image from the viewfinder, allows you to [...]

Whether inspired by the vaults of Fallout or the mysterious wrist device worn by [Turanga Leela], we’re just glad to see someone finally made a wrist-worn cellphone, The Ultimate Wrist Watch, as the creator [Rob] calls it, is based on his Motorola Defy smart phone, tucked inside a neatly modified iPod wrist band meant to hold a [...]

[PC486] wanted to add Bluetooth to a simple shelf stereo system. But if you’re going to go wireless, why not develop an all-in-one solution. His adapter turns on the stereo and feeds it audio all from a smart phone. This is his roommate’s hardware so cracking it open and grabbing an iron wasn’t really an option. He [...]

Sensordrone is a sensor-filled wireless dongle for use with a smart phone or other computer-like device. But perhaps this is better explained as the thing that makes your smart phone work exactly as the original Star Trek tricorders did. In one had you have the main unit that displays data, in the other you hold [...]

So [RobB] wanted to take out all the light switches in his house. His plan was to replace them with a system that could be operated from his smart phone. But his wife insisted that there still must be some way to control the lighting directly — we have to agree with her on that one. The [...]

There’s a good chance that you use a MEMS accelerometer every single day. It’s the small chip that let your smart phone automatically adjust its screen orientation. They’re great chips, and since they’re mass-produced you can add them to your projects for a song (if you can abide the tiny packaging). But we have no idea [...]

[Joseph] wrote in to share this home automation system he’s working on as a college project. He calls it the Room Engine and the house-side of the hardware is built on top of the circuit you see here. This is the most basic part of the REBoard, which is meant to connect to a computer [...]

[Nate] over at Sparkfun put up a great tutorial for using the SPOT personal satellite communicator with just about any microcontroller. These personal satellite transmitters were originally intended to pair with the bluetooth module of a smart phone, allowing you to send a short 41-character message from anywhere in the world. Now, you can use these neat [...]

Even though everyone with a smart phone has a small, powerful computer in their pocket, we haven’t seen many applications of this portable processing power that use the built-in camera. [Michael] decided to change this and built an LED matrix that displays the data coming from the phone’s camera. For the build, [Michael] used two [...]

Here’s an interesting experiment that lets you simulate PenTile displays on a normal LCD monitor. [Barrett Blackwood] wanted to test out how some graphics look on PenTile RGBG displays with different pixel densities. These PenTile RGBG matrices are sometimes used in OLED displays. For instance, the Nexus One smart phone features a display of this [...]

Hack a Day
Instructables user [tcollinsworth] is a big fan of his Android smart phone. He practically carries it with him everywhere, so he figured it would be cool to integrate as many of his home electronics with the phone as possible. His garage door openers seemed like easy enough targets, and while he was in the garage, [...]

Hack a Day
The polished quality of this hack isn’t quite there, but we love the ingenuity and exploration exhibited. [Paulie1982] shows us how to make an old cellphone work with the rays of the sun. You can see above that he’s added photovoltaic solar cells to the back case of what looks like an old smart phone. [...]

[Tim] is showing off the first step in his home automation projected with this smart-phone garage door interface. In the video after the break you can see him open and close the garage door with the touch of a button. There’s also an open or closed indicator that he can check when away from home. [...]
