When [Peter] saw the Sparkfun Magician robot chassis in a recent new product post, he knew instantly that he had to have one for a telepresence project that had been kicking around in his head for a while.
Onto the robot chassis, he added an Arduino to provide the brains of the bot, an Adafruit motor shield for controlling the wheels, and a Pololu Wixel for wireless communications. An iPhone is mounted on the top of the robot, which communicates with his laptop using Apple’s Facetime app. The robot is controlled from his laptop as well using the Wixel, which enables him to direct the Magician chassis as if it was attached via USB.
While he thinks the robot is pretty neat and that it works well, [Peter] already has improvements in mind. The robot chassis is a bit weak on anything but smooth surfaces, so a new set of motors and wheels are likely the first changes he’ll make. He wants to add a servo-based aiming mechanism for the phone’s camera, as well as some sensors to prevent the bot from taking a nosedive off his table.
iPhone aside, this is probably one of the cheaper mobile telepresence setups we’ve seen, so we can’t wait to hear how the improvements work out, and how much they add to the robot’s cost.
It’s no secret that the audio quality of the iPhone’s built-in speakers isn’t exactly what you would consider to be hi-fi. Sound quality aside, there are plenty of times where even the volume doesn’t do the music justice. While you can always go out and buy a fancy dock to amplify your iGadget’s sound, artist [Christopher Locke] has a different take on the subject.
For a while now, he has been constructing what he calls “Analog Tele-Phonographers”, metal sculptures that can be used to amplify a mobile phone’s audio. Built out of steel and old trumpets, his audio sculptures require no electricity, instead utilizing the same amplification technology as the original phonographs.
While the Tele-Phonographers won’t make your iPhone sound like a high quality tube amp, they do undoubtedly increase the phone’s volume and they are nice to look at. We can certainly get behind this sort of recycling/reuse of old items.

This Daft Punk helmet replica is beautiful to look at, but the deeper we delve into the build process, the more we begin to think that the entire project is a piece of artwork. [Harrison Krix] has been working on it for months, and just posted his three-part build log in September. Check out the video and the links to all three parts after the break.
Now [Harrison] isn’t new to prop replica scene. He’s the guy responsible for the other fantastic Daft Punk helmet we saw last year. He’s tapped the same fabrication skills to churn out an equally impressive chromed helmet, complete with addressable flashing LEDs. He built his own mold to create the body of the helmet, reminding us of the Storm Trooper helmet replicas we saw in July. While this was off being coated in chrome, he got down to business with the electronics.
The visor of the helmet has a red LED marquee. This, along with the multicolored visor sides and ear pucks, is controlled by an Arduino yellow jacket. The lights can be controlled by an iPhone app that connects to the helmet via WiFi, letting a user push custom messages to the display, and alter the light patterns. The build shines on the inside as well as the outside with an incredibly clean LED matrix build, and clever control placement for switching each part on or off.

Disposable coffee maker
[Sepehr] didn’t have a coffee maker, and the local coffee shops were all out of joe. He got his fix by making a drip coffee maker out of disposable cups and knives.
Flexible braille display
Thin film technology is being developed to help the visually impaired. This flexible OLED display has embedded muscle cells which create a braille display. [Thanks Aaron]
Printable iPhone tripod mount
Looking to make those iPhone videos a little more stable, and the pictures a little less blurry? Try out this printable tripod mount that [Chris] came up with.
Arduino macro photos
Speaking of photographs, [Daniel] wrote in to share some macro pictures he took of an Arduino. They’re sure to be of interest to those readers who love everything Arduino.
Carpeting a mouse
Add a unique texture to your mouse by covering part of the body with fabric. The lower half of the mouse case above is covered in a carpet-like material [translated]. [Thanks Clicker]
[Jean] was shopping around for a vintage stereo receiver, and happened upon a broken, but repairable Marantz 4240. After getting things back to working order, he thought it would be great if he could use his iPhone to remotely control the unit (PDF Writeup, Schematics and Code).
He scrounged around for parts, and after locating a PIC and a handful of parts from old copiers and printers, he got down to business. He etched some custom boards to house electronic bits, then strapped motors to the volume and source selection knobs. He also rigged up the push button power switch on the receiver, using a small servo and a bit of string.
Now, he can control everything using his iPhone, which communicates with the stereo over WiFi. While the power, volume knob, and input selector can be triggered remotely, he still has the ability to tweak any of these items manually if desired.
We think that this is a great way to add modern amenities to vintage electronics, without ruining the aesthetics of the components. Don’t take our word for it though, check out the video demonstrations [Jean] but together after the jump.

[Alex Busman]’s first foray in iOS programming looks like a pretty useful tool. He came up with Ohm Sense, an iPhone app that will take a picture of a resistor and calculate the value based on the color bands. It’s a great tool that we wish we had when we were starting out. At 99 cents, the app is also much cheaper than the emotional cost of our relationship with Violet.

We’re still waiting for our [Lt. Uhura] style earbuds. But until then, can we interest anyone in a set that will stand up to some abuse?
Solder Pot Scavenger
[Felicitus] says we should get a solder pot and use it to scavenge for parts. His method looks pretty easy and it’s cheaper than buying a rework station for this purpose.
Turn all your hacking skills loose to beat the heat. That’s what [Stephanie] did when she added iPhone control for an oscillating fan.
Graphing equations and crunching numbers wasn’t enough for [Drew]. He went and figured out how to make his TI-84+ play music off of a thumb drive.
Don’t let anyone out-geek you at company parties. Beef up your arsenal with this resistor color-code necktie. And yes, you can wear it with a T-shirt!
