Voice Controlled Lock? Almost…

November 25, 2009 by Jakob Griffith 13 Comments

If you watched the video before reading the article (like we did) and started shaking in your boots at a voice controlled lock system, prepare to be disappointed. His spoken commands are actually to his son to press the appropriate keys on a keypad off screen, the lock is not actually voice controlled.

But still, [Michael Krumpus’] door lock is pretty astounding. By using a torn apart CD drive he easily attains a nice fast and smooth linear motion to bolt and unbolt his door. It wont open his door like some locks we’ve seen, but it will probably be added sometime in the future…right alongside voice commands.

$100 Free From Your Favorite Hobby Supplier!

November 24, 2009 by Jakob Griffith 88 Comments

We were wary at first when the email came in with the headline “SparkFun is having a free day” and figured surly this is in relation to recent events? But no, after 7 years of loyal customers, SparkFun is simply giving back to the community.

It’s interesting to think that without their services, we wouldn’t have some of the amazing hacks we introduce every day. Such as the DIY mood lamp, or Cell phone alt-variometer, or Arduino iPod remote control. And their free day will allow some disadvantaged hackers the ability to finally flex that muscle sitting between their shoulders. What do you plan to make?

Mark your calendars folks, On January the 7th 2010 SparkFun is giving every household a $100 (until they reach $100k), if that’s not an incentive to wake up early, what is?

As a side note, do you think we’ve had enough posts about SparkFun lately?

[Thanks Diego]

SparkFun Product Used For Immoral Hacking

November 23, 2009 by Jakob Griffith 43 Comments

While we have our fun ethically hacking, its very easy to forget that sometimes our ideas could be used with malicious goals. Take for instance SparkFun’s BlueSMiRF – the device’s original intention is simply to act as a wireless serial cable replacement. After hackers discovered several PIN pads use a serial interface, they put one and one together to steal several hundreds of people’s personal bank accounts.

It seems SparkFun is getting a lot of heat lately, but we’re glad they stand up and address these issues. You can check out the original news clipping here.

LED PDF From TI (KUWTA)

November 21, 2009 by Jakob Griffith 3 Comments

[Satiagraha] let us know that Texas Instruments(TI) has given out a neat “LED Reference Design Cookbook” PDF. The document contains 17 some odd little projects featuring different TI ICs and ways of using them to control LEDs in things from backlights to torches to solar lanterns to advanced PWM control! Sure the document is biased towards using TI equipment, but that shouldn’t stop you from recreating, modifying, and generally just having fun with their designs in your own productions.

Axe Your Camera (again!)

November 19, 2009 by Jakob Griffith 9 Comments

[Maurice] let us know that his latest photography tool for hackers, the Camera Axe 3.0, is now available. The original allowed you to trigger a high-speed flash and camera from a multitude of sensors, including light and sound. The new one does all that, but also: allows multiple cameras or multiple flashes, clean up of software to make it more user adaptable, and the best (arguably the most important) part – cheaper components! All that and more under the Creative Commons that we do love so much. Keep up the amazingly detailed and just pure awesome work [Maurice].

(Mini) Earthquake In Your Living Room

November 19, 2009 by Jakob Griffith 16 Comments

Today we stumbled upon [jimthree’s] Seismic Reflector while looking at projects that employ the Processing language we mentioned a few days ago. Utilizing a Boarduino and some vibration motors from a game controller, the Seismic Reflector does just as its name implies – rattles itself around whenever there is an earthquake. While this does seem a bit silly at first, we were fascinated to learn there have been 165 earthquakes just in the past week and almost no news reports, suddenly this device got a lot more interesting!

Rotating Radar Visualization

We ask, who wouldn’t want a rotating motion and distance tracking radar? Sure in today’s day and age anyone could purchase a wide-angle sonar or IR solution that achieves the same goal, but [LuckyLarry] took it old school and made his own rotating radar. He used an Arduino, servo, and ultrasonic sensor as a base to gather data, and the open source programming language Processing to draw the data on the screen. He says it’s a little inaccurate currently, but will try out some other sensors in the future.
