"We had a chance to play with Research In Motion’s upcoming BlackBerry Bold handset tonight, and we came away happily impressed. To start things off, the keyboard felt easy enough to use, at least easier than the 8830 we’re often forced to use for work email. Gone are the sharp protrusions, replaced with a nice flat surface upon which to click.

This is a really cheap and probably illegal shortwave transmitter, don’t build it. It just feeds the output from an LM386 audio amplifier directly into the power pin of a crystal oscillator can to produce AM-modulated shortwave radio frequencies. This works better than one might expect — this particular oscillator seems to provide a stable waveform with voltages anywhere from 2.0v to 5.0v!

engadget.com says Nokia’s finally fessing up to its latest E series QWERTY phone, but took this one in a seriously surprising direction… for Nokia, anyway: thin. The E71 is one of the thinnest phones we’ve ever seen exit the doors of the Finnish giant, at 10mm thick, but there’s still plenty of room for everything you’d expect out of an E series phone like WiFi, HSDPA, A-GPS and even a 3.2 megapixel camera and a front facing camera for video chat — the main place the E71 differs on specs from its new E66 sibling is the 2.36-inch QVGA screen, just a fraction of an inch smaller. The E71 even manages to squeeze in extra battery, with 20 days of standby, 10.5 hours of GSM talk or 4.5 hours of 3G talk. There’s 110MB of built-in storage and a microSD slot if you grow out of that, and the same business / personal switcher of the E66. Folks accustomed to previous Nokia QWERTY phones in the form factor like the E62 will find the screen noticeably smaller, but with the same number of pixels and an incredibly pocketable form factor there’s plenty to love about this new entry.
Cool microcontroller project from kalinda. In this project he used microcontroller AVR Attiny2313 that is perfect for controlling the 13 pins required for the matrix of LEDs. he has also provided pins in the most optimal order to occupy as little as possible.
