Hanging out at one side of the Atmel booth at Maker Faire was [Pamungkas Sumasta] who was showing off his Arduino cellphone called Phoenard. We really like the form-factor but its hackability is where it really shines. [Sumasta] showed off the menu system which is quite snappy and makes it simple for you to add your own applications. Software isn’t the only thing you can customize, as there’s a connector at the bottom of the phone. He showed off a breadboard attachment which was hosting LEDs of various colors. Their intensity can be altered using a simple slider app on the touchscreen. But there’s more power if want it. Also on exhibit was a self-balancing robot body which has a connector at the top for the phone.
[Sumasta] won the Atmel Hero contest and we assume that’s how he made it all the way to San Francisco from The Netherlands for Maker Faire. You can learn a few more technical details about Phoenard on the Facebook page.
The Federal Trade Commission really doesn’t like robocalls and other telephone solicitors selling you vinyl siding or home security upgrades. The FTC is even offering $50,000 to anyone who can do away with these robocalling telemarketers, and [Alex] looks like he might just claim the prize. He developed The Banana Phone, a device that eliminates those pesky telemarketers.
The basic idea of the Banana Phone is requiring callers to enter a four-digit pass code (played via text to speech over a relevant song to prevent a bot from getting through) before connecting them to the main line. Once a caller has been verified as human, their number is added to a white list so they won’t have to listen to [Raffi] every time they call.
The Banana Phone uses off-the-shelf parts including a Raspberry Pi and a phone/Ethernet adapter with the total build cost under $100. You can check out a demo of the Banana Phone in action after the break starting at about 2:25.

Put that old Android phone to good use by mounting it on the wall as a smart thermostat. This open source hardware and software project lets you replace your home’s thermostat with an Android device which adds Internet connectivity and all that comes with the increase in computing power.
The brunt of the hardware work is taken care of by using an IOIO board which makes it easy to interface any Android device with the simple hardware which switches your HVAC equipment. We’ve been waiting for the launch of the new IOIO design and if it comes in at a lower price as has been rumored that makes this project in the price range of the least expensive of programmable thermostats (assuming you already have an Android device to devote to it). Simply etch your own board to host the relays and voltage rectifier and you’re in business.
There is a client and server app, both free in the Play Store. The server runs on the wall-mounted device with the client offering control via a network connection. The features of the system are shown off quite well in the video after the break.
This sounds like a perfect use for that phone you ripped out of the pages of a magazine.

Here’s how you can have a hands-free, no worries about the battery, Android experience while you drive. [Steve] removed the head unit from his car and replaced it with a Samsung Galaxy SIII Android phone. The look is pretty nice, but we do have a few suggested improvements if you try this one for yourself.
It started simply by removing the factory stereo which left a double-height opening in the dashboard. [Steve] cut a piece of wood to fit the gaping hole, painting it a grey that would compliment the interior colors of the car. The phone is mounted on this plate, with plenty of room for the USB and audio cables. From there it is finished up with another wooden plate which has a cutout for the touch screen. See the final project, as well as glimpses of the installation, in the video after the break.
[Steve] demonstrates using the GPS features and playing music. We’d improve this in a couple of ways. First off, using something like the IOIO board you could add a physical volume knob, which we’re not interested in giving up for a touch screen quite yet. If you were willing to go the extra mile, a CAN-BUS chip could be added too that would monitor button presses from the steering wheel music controls.

In case you haven’t noticed from my many comments on the subject, I drive a VW bus. It is a 1976 Westfalia camper with sage green paint and green plaid upholstery. I absolutely love it and so does the rest of my family. We go for drives in the country as well as camping regularly. We have found that the kids have a hard time communicating with us while we’re going higher speeds. These things aren’t the quietest automobiles in the world. Pushing this bread loaf shaped hunk of steel down the road with an engine that might top out at 75hp results in wind noise, engine noise, and of course, vibration.
I decided to employ a really old hack to put two functional telephones in the bus so my kids can talk to my wife (or whoever the passenger is) without screaming quite so loud. This hack is extremely easy, fairly cheap, and can be done in just a few minutes. The result is a functional intercom that you could use pretty much anywhere!

Why not that is, if you have a prosthetic arm. Although it’s hard to believe we haven’t seen this before, [Trevor Prideaux], according to [The Telegraph’s] article, “has become the world’s first ever patient to have a smartphone docking system built into his prosthetic arm.”
[Trevor] was born without a forearm, and, as he puts it, he’s used to adapting to things. However, he thought others might be struggling with the same problem, especially those that become disabled later in life. Once their help was secured, Nokia and the Exeter Mobility Centre got to work on his new limb and produced a prototype in five weeks!
[Trevor] is quite pleased with his new phone docking system. Texting especially is much easier and safer, and the phone can be removed when needed for making calls. We love to see hacks like this where people enhance their abilities using technology! For another hack helping those with disabilities, check out this wheelchair elevator/winch made for a non-accessible apartment.
[Adam Ben-Dror] recently tipped us off to a project that he worked on recently. In this build he gutted an old candlestick-style phone and added modern technology to make it work as a cordless phone. We really liked this project because he married together new and old technology into an elegant package. There are a few hacks that he had to perform to get this to work. One was converting the rotary pulses into DTMF tones. The other was making the cordless phone that he gutted recognize when the phone was on or off of the hook.
Details of his build after the break. Continue reading “Candlestick phone goes modern.”
