Solar charging station on a dog
The Solar Dog prototype charger from Erik Schiegg is a solar panel attached to a dog sweater. I'm not sure how efficient it is, but I could see this being handy. [via recombu]
My Android phone is charged in no time... The dog feels good and I'm feeling good and planet mud is turned a little bit more into planet earth. But this idea would be interesting for farmers around the world, letting their animals collect electricity, too.

Alt.CES: Nexus One teardown

I love how our pals over at iFixit are always the first in line to buy new gadgets as they come to market, so they can race them back to the shop to take them apart and find out what makes them tick. Their excitement and curiosity is almost palpable, and of course, we all benefit from what they find. Kyle and company just plunked down a princely 530 bones for the exploratory thrill of field-stripping the Google Nexus One.
The Nexus One, manufactured by HTC, is the latest and greatest Android phone. It sports:
* A 1 GHz Qualcomm (QCOM) Snapdragon processor.
* A 3.7" 480x800 widescreen WVGA AMOLED display.
* A 5MP digital camera w/ LED flash that also records .mp4 video.
* 802.11n wireless capability for when you can't depend on 3G.
* 7 hours of 3G talk time from a removable 3.7V, 1400 mAh lithium battery.

Bluetooth Ericofon
SQNewton didn't just crack open a bluetooth headset and cram it into a cool retro handset casing; he developed his own hardware to produce a fully-functional, self-contained phone that uses the Ericofon's original rotary dial, gives dial and busy tones, mimics the original Ericofon ringer, and has voice-recognition dialing to top it off.

The Copenhagen Wheel

The Copenhagan Wheel recently demonstrated at the Copenhagen Conference on Climate Change is a clever device that can store energy every time you apply the brakes and then reapply it in the form of motor assist as you ascend a hill on your bicycle. Developed by MIT researchers, the Copenhagen Wheel also acquires speed, distance, and direction data from an array of sensors inside the device and transmits it via Bluetooth to the cyclists mobile. [via geekygadgets]
Over the past few years we have seen a kind of biking renaissance, which started in Copenhagen and has spread from Paris to Barcelona to Montreal," says Carlo Ratti, director of the MIT SENSEable City Laboratory and the Copenhagen Wheel project. "It's sort of like 'Biking 2.0′ -- whereby cheap electronics allow us to augment bikes and convert them into a more flexible, on-demand system.

The Mobile Mobile
What do you get when you hang up a bunch of outdated cell phones, and hook them up to the Internet? Well, you are in luck! James Theophane writes in to share his group's latest project, the Mobile Mobile. Using 50 company phones that had recently been replaced, they created an installation that plays the song "Carol of the Bells". The project is installed at their headquarters, however they also have an interactive streaming interface.
Wondering how one hooks up a bunch of old cell phones to do this kind of project? So were we, and they graciously agreed to fill us in on the details:
The plan was to make 50 mobiles to each play a different note of a Christmas carol, and flash in time. We set up a test mobile phone - an HTC Touch - to connect to a wifi access point whilst being powered by a charger.
We 'ping'ed the IP address of the phone for two days to verify that it would remain contactable. The phone did get a tiny bit warm, but it worked. We noticed that the ping time changed significantly between different power modes on the wifi of the mobile - from 100ms down to about 2ms on 'performance'.
The plan was to write a small program that ran on the phone that understood a small set on instructions and have a controller running on a PC sending the commands. The basic list of commands was: light on/off, change colour 'wash' and beep.
The first challenge was turning the backlight off - WinMobile is a multitasking OS running WindowsCE as the kernel. The power management subsystem allows you to suggest power settings, but the OS takes into account all the running programs needs.
Turning the backlight fully off proved problematic in the project timescales (a matter of days). Next was beeping. The PC has always had a speaker that could beep - it was connected to the chip that controlled the keyboard - so has had a corresponding function e.g. in windows the MessageBeep function.
WindowsCE was designed for a range of platforms and embedded controllers and it looks like beep was not a core function. Luckily the Microsoft developers included some sample code on how to implement a MIDI sound system expecting hardware manufacturers to license third party full musical instrument libraries. It looks like the manufacturers kept with the simple sine wave sample code implementation. This was good enough for our mobile phone beeping musical rendition.
The program on the phone was written in Microsoft .Net C# and consisted of two parts: one registering with a web service - logging the fact that it was still alive and its current IP address, and two a UDP listener - listening for commands from the controller over the network.
The controller was written to read the midi file of the Carol and send the individual notes to individual phones at the right time. Using UDP instead of TCP and the 'performance' setting on the phone meant that the commands arrived promptly on the phones.

Mot Droid teardown

Our buds at iFixIt wanted to see a teardown of a new Motorola Droid, so they offered a $300 bounty to the first person who'd field strip and document the deconstruction of their Droid. Dr. Wreck answered the call. Here are the results of his investigation.
Kyle, of iFixIt, writes:
The phone was quite a handful to take apart, having a multitude of hidden screws and latches. Interestingly enough, the sliding mechanism consisted of two rails that were imbedded within the screen portion of the device, providing a simple and effective method to slide out the keyboard. Sadly, no aliens or hidden messages to Princess Leia were found inside.

DIY Palm Touchstone car mount

This has to be the coolest car mount for any mobile device out there. Originally designed for home use, maker remington870_20ga from the everythingpre.com forums wired a stock Palm Touchstone Charging Dock to run directly off his car battery using off-the-shelf components. Not only do you get an unencumbered view of the screen, your mobile device gets a chance to charge itself without all the messy cables.

Compact cellphone microscope

This novel approach to cellphone microscopy from Dr. Aydogan Ozcan from the University of California, Los Angeles, foregoes bulky lenses and magnifies electronically.
For this electronic system of magnification, inexpensive light-emitting diodes added to the basic cellphone shine their light on a sample slide placed over the phone's camera chip. Some of the light waves hit the cells suspended in the sample, scattering off the cells and interfering with the other light waves.
