Ever wanted to be 'logged in' to your AVR microcontroller? Ever thought it would be cool to 'cat' a register to see its contents? Have you always wanted a way to power up and power down individual peripheral sub-systems of your AVR or Arduino in *real time* ? Me, too, so I wrote the AVR Shell, a UNIX-like shell.

Morning Types Crash Faster Than Night Owls, Study Says [Sleep]

Morning Types Crash Faster Than Night Owls, Study Says [Sleep]: "

The early bird may get the worm, but there's something to be said about burning the midnight oil. In fact, according to a new study, staying up later and longer may increase alertness and productivity more than being an early riser.

According to the study as reported by Scientific American:

An hour and a half after waking, early birds and night owls were equally alert and showed no difference in attention-related brain activity. But after being awake for 10 and a half hours, night owls had grown more alert, performing better on a reaction-time task requiring sustained attention and showing increased activity in brain areas linked to attention.

Of course we wouldn't be surprised if another study were to come along touting the opposite conclusion, so it's worth taking this news with a grain of salt, but the post is an interesting addition to the early bird versus night owl discussion. If you're looking to find your peak performance time, check out our previous post on the best times morning people and night owls should get work done.

Nokia Tosses Another OSS OS Into the Mobile Mix

Nokia Tosses Another OSS OS Into the Mobile Mix: "
Nokia on Thursday announced the N900 smartphone, a mobile device running the Linux-based Maemo operating system that the company typically uses for its tablets. The device runs a Mozilla-based browser and offers still and video photography, an FM radio and 3.5G and WLAN connectivity. Maemo is the operating system used in Nokia's tablets, and the Finnish handset maker's description of the N900 shows it's moving to converge the computer, the Internet and the mobile phone. Nokia sees the Maemo OS as driving its new technology, and the N900 as merely the hardware to contain the OS."

Nokia's Maemo 5 RX-51 / N900 tablet gets exhaustively previewed: "

Eldar Murtazin at mobile-review teased us with that shot of Nokia's RX-51 / N900 Maemo 5 tablet earlier today, and now he's back in force with a detailed preview. We're talking tons of hardware pictures and screenshots of what stands to be the standard-bearer for all Nokia devices going forward, and while we'd love to tell you all about how impressed we are with what we're seeing of Maemo 5 and how disappointed we are in the Rover's resistive touchscreen, we won't hold you back -- hit the read link and dive right in.

New Maemo 5 screen shows fascinating, unique array of settings

New Maemo 5 screen shows fascinating, unique array of settings: "

Nokia may have shot down rumors that it was planning to completely replace its Symbian OS with Maemo, but that hasn't taken all the shine off the mobile OS, and a new, lone screenshot has now surfaced to further stoke those flames of anticipation (it's okay, you can admit it). As you can see above, however, it's not exactly the most exciting of screens to capture, but is supposedly the real deal and not just another SDK sourced image.

[Thanks, Eric]

Turn Your Car's Cup Holder Into a Laptop Stand [DIY]

Turn Your Car's Cup Holder Into a Laptop Stand [DIY]: "

Need to use your laptop in your car? Don't purchase a pricey laptop stand for the passenger seat or shell out for a dashboard mount. With some creative DIY-action you can turn your cup holder into a laptop stand.

Mike Davis needed a way to use his laptop in his truck and have a nice stationary platform to put it on. Unfortunately commercial models ran upwards of $300. After scoping out the cab of his truck and doing some brainstorming he realized he could build his own stand and use the center console cup holder as a base.

With $30 worth of parts—mostly pvc pipes, fittings, and a sheet of plywood—and a single afternoon of work he had a laptop stand for his truck that holds his laptop so well it doesn't budge even when swinging the truck around corners.

Check out the full build guide below to see step by step photos and additional information. Have a unique in-car DIY hack like Mike's laptop stand? Let's hear about it in the comments.
