Raspberry Pi releases Debian Wheezy

wpsuperadmin Debian, On the Web, raspberry pi Leave a Comment

It has arrived: We are pleased to announce the release of our  first SD card image based on the Raspbian distribution. This is the result of an enormous amount of hard work by Alex and Dom over the past couple of months, and replaces the existing Debian squeeze image as our recommended install. Notably, it is the first official image to take full advantage of the Raspberry Pi’s floating point hardware for, amongst other things, much faster web browsing SOURCE: Now to figure out if I can upgrade. Sounds like it would be worth the trouble to upgrade from scratch.

Checking out the temperature of a Raspberry Pi

[Remy] has access to a very nice Fluke thermal camera, so when his Raspberry pi came in he pointed the thermal camera at the Raspi (Spanish, Google translation) to see how far this neat computer could be pushed before it overheated. There are three main sources of heat on the Raspberry Pi: the voltage regulator, the USB/Ethernet controller and the Broadcom SoC. At idle, these parts read 49.9° C, 48.7° C and 53° C, respectively; a little hot to the touch, but still well within the temperature ranges given in the datasheets for these components. The real test came via a stress test where the ARM CPU was at 100% utilization. The Broadcom SoC reached almost 65° C while the …

How To: Fly With Homemade Electronics

wpsuperadmin On the Web, Tutorials Leave a Comment

Something I found that could be really helpful from “About once a month I see an article about some ambitious maker who’s project  created an alarm at airport security. Most makers who travel with homemade electronics and other prototypes have a fear that their innocuous project wil catapult them to the front page as a threat to national security. While these news reports make up a good list of how to travel with bespoke electronics, but what I really want to collect is information on how to avoid getting into these situations to begin with.” Read More

Microsoft Windows 8 Consumer Preview detailed impressions

wpsuperadmin On the Web Leave a Comment

The early days of Windows were inauspicious ones. Sitting on top of DOS, it was hardly a revolution in personal computing — instead it felt like a disjointed platform perched uncomfortably atop a command prompt, ready to come crashing down at any moment. That’s what it was, and often that’s what it did. The early days of Windows required constant jumps from GUI to shell as users ran a wide assortment of apps, only some of which played nice inside a window.It was over a decade later, after Windows 95, that the operating system would truly ditch its DOS underpinnings and feel like a totally integrated system. Why are we reminiscing? Because we’re reaching that same point again. With the Windows …

Windows 8 Developer Preview is available for download now! From Engadget Got a brain full of Windows 8? Can’t stop obsessing about it?
