Engineer makes light-up business cards with 555 timer, proves PCB skills

Sure, there have been some pretty creative variations on the standard paper business card, but if you're looking to make a career in electronics engineering, card stock isn't necessarily the best option for material. Such was the case for one student, who had the canny idea to make a card that demonstrates his printed circuit board know-how. He used a 555 timer that outputs a clock to the LEDs on the biz card, and placing a nine-volt battery on the terminals sets off the mini light show. See for yourself in the video below.

7 Things Buddy Media Did Right To Become an $800mm+ Company

buddyThe first thing, of course, is that Mike Lazerow, the founder of Buddy Media, met me. This sounds egotistical, but everything I did in the encounter was bad for me. He cold-emailed me in 2007. I had just launched a company called Stockpickr.com. He liked the idea and his time with GOLF.com (which he had built and sold to Time Warner for $24mm) was running out and he wanted something to do. He liked the idea of Stockpickr and wanted to run it. Specifically, his email said:

New software uses facial recognition to defend against prying eyes

Having the right programs and hardware to keep the information on your display safe from prying eyes is never a bad idea, and new software from Oculis Labs offers a very interesting take on how to do just that. It's called PrivateEye, and it utilizes facial recognition to automatically pixelate the contents of your display when you look away.

If you step away from your system and someone else decides to sit down and poke around, PrivateEye will present a confusing jumble of garbled text. It'll even notify you if someone tries to peek over your shoulder -- and display a picture of your peeping Tom, throw up an alert, or sound an alarm.

Check out the video embed after the break, and share your thoughts in the comments!

Pro tip: Avoid unsightly contextless crotch shots on the Google+ app with better descriptions

Google+ app

No, Google+ app. Not "this." Because "this," being a comic-drawn crotch shot, is not what I wanted folks to focus their attention on when I linked to Peter Ha's TechCrunch piece debunking the Bloomberg story that Microsoft had "shut out" HTC from manufacturing Windows 8 devices. My only comment -- "This."

(BTW, Bloomberg's is a fairly ridiculous story, led by the all-too-familiar "people with knowledge of the matter." If you didn't bite on it, kudos.)

But if you'd seen my post from the Google+ app, all you'd know is that apparently I like cartoon pr0n. (Not that there's anything wrong with that, I suppose.)

This all stems, of course, from Google's recent redesign of the Google+ app. And for the most part, it's a beautiful redesign. Images are large. Posts are easy to follow -- so long as you don't actually link to anything. It's something I noted at the outset but apparently forgot because I'm using G+ on the desktop side most of the time. It's also a step backward. The app used to have this problem, then it got fixed in April. Now? It's gone again, at least in the stream view. 

I've learned my lesson. This'll put an end to the one-liners. I'll use 20 words when only one is needed. Or Google could just add back a little beta of metadata.

Regardless, learn from my mistake. Only you can prevent inadvertent contextless Google+ crotch shots.

Chrome 11 beta adds new experimental APIs for proxies, Web navigation

google chrome 11 proxy
Google Chrome 11 -- which just recently made the move to the browser's beta channel -- has received a minor update that gives developers access to two new APIs.

The first is a full-featured proxy API, which will, for example, allow users to set different proxy servers for normal browsing and Incognito mode. Proxy auto-config scripts are also supported by the API.

The second -- Web Navigation Extension -- is a bit more expansive. This API will allow devs to build everything from more powerful safe browsing extensions -- like Traffic Light -- to data analysis and reporting extensions.

Both APIs are currently experimental, so you'll need to enable them on the about:flags page to try out any relevant extensions. Apart from a proxy example built by Google and shipped with the Chromium source, we're not aware of any examples just yet, however. We'll let you know when we spot any slick, new extensions which do surface.

Windows 8 App Store images leaked?

windows 8 app store
Windows 8 images continue to leak onto the Internet, despite Microsoft's wallpaper-based pleas to those with access to the early releases. Today's installment courtesy CNBeta shows the upcoming Windows App Store, which will likely feature prominently in Windows 8.

We've got our doubts about the authenticity of the image. In addition to showing several of the built-in games which already ship with Windows, Opera is listed -- and a competing browser seems like an odd inclusion this early on. Of course, with the browser ballot still in place in the EU for quite some time, Microsoft would probably need to include rivals like Opera and Firefox to stay out of trouble. We're also not sure why Clickgamer is shown beneath Angry Birds instead of Rovio -- the game's actual publisher.

It's still early, of course, so it's entirely possible that the Windows App Store image is genuine but merely using placeholder images and text for now. Anyone else thinking Windows Marketplace might be a more logical name? You know, to keep things consistent with Windows Phone and keep Apple's legal eagles at bay.

Open-mesh PC case keeps heat, dust bunnies at bay

open-mesh-pc-case-keeps-heat-dust-bunnies-at-bay

If you haven't done it in a while, opening your PC case can be like a slasher flick -- you know you'll see something disgusting, but you're never sure what. Taiwan's YoungYear Electronics claims to stop the horror with its Green Mesh case, which has neither fans to suck dust, nor filters, and keeps your components cool with a "chimney effect" instead. It's this same action that repels dust out the top, so that only one quarter the usual amount of filth is drawn in -- according to the company. The only downside is that with poor heat dissipation, the maximum power supply unit size is 300 watts -- which probably scratches it off the list for most modders or power-users. For the rest, if you don't mind your computer's innards blowing in the breeze, at least you'd have no nasty case-opening frights.
