DIY: 500 LED Extreme Flashlight

Posted: 28 Mar 2010 07:00 PM PDT

So you think you’ve got a bright flashlight. You got nothing! This guy built his own, with 500 LEDs (which consume a shockingly low 50 watts when it’s powered up. This guy is so good, he wasn’t just content to build the most ridiculously bright LED flashlight in the world, oh no. He also built a custom interface for it that allows him to make it flash, control the power levels, and even signal for help. So here’s to you, extreme flashlight guy. Sure, you did this a while ago, but it’s so cool it deserves a mention on a slow Sunday afternoon.

iFixit tears down the DSi XL

Posted: 28 Mar 2010 04:57 PM PDT

No Tegra chip for you! iFixit tore down the Nintendo DSi XL and found, not surprisingly, a bigger DSi. It’s running the DSi’s ARM processor and the motherboard is big enough to fit in the case, but that’s about it. Click through for more findings:

* Nintendo is again using a custom ARM CPU, manufactured in December
of 2009. This chip is marked identically to the DSi, and definitely
not the Tegra chip that had been rumored.

* The logic board grew proportionally to its casing. We’re sure
Nintendo’s engineers were happy with not having to pack as much
electronics as possible in a smaller design. In this instance,
Nintendo’s going against the normal trend in electronics

* Battery capacity is significantly greater than the DSi. The DSi
uses an 840 mAh battery compared to the DSi XL’s 1050 mAh battery.
Given the internal similarity of the XL to the original DSi, we assume
the extra juice helps power the larger-sized screens.

* The DSi XL weighs in at 314 grams, about 45% more than its smaller
DSi cousin (only 217 grams). A significant portion of the heft comes
from the larger screens, and 4 grams comes from the added battery
juice. The XL is really on the outer limits of what people consider to
be portable — especially for a hand-held game console.

* Nintendo redesigned the battery connector to eliminate a long ribbon
cable spanning the width of the old DSi.

* The lower display is held in place solely by the pressure of the
logic board secured over it — no screws!

Why not a third iPad App Store post?

Posted: 28 Mar 2010 04:23 PM PDT


I’m beginning to be suspicious of the slow trickle of iPad App Store news. I mean, first there was a leak, then there was a slightly more comprehensive leak, and now there’s a video… I wouldn’t be surprised if people were to find iPads hidden among their Easter eggs later. Well, deliberately leaked or not, this video shows what to expect from the store, and yes, it’s almost exactly what anyone would have guessed. It’s a little disappointing that they’re doing it in such a safe way, but I guess they can’t risk too much on a crazy UI when they’re trying to popularize the form factor.
