New Siri Hack Controls Your Car

Siri can make appointments, tell you the weather, but now she can start your car as well!

After we showed you how Siri could be hacked to use a custom proxy and execute custom commands, we knew it wouldn’t be long before additional hacks would start rolling in. [Brandon Fiquett] thought it would be great if Siri could remotely control his car, so he built this functionality into Siri using [Pete’s] proxy software.

The hack relies on the Viper remote start system he had installed in his car, along with a few modules loaded into his proxy server. His proxy server tweaks allow Siri to interpret a preset list of commands such as “Vehicle Start” and “Vehicle Arm/Disarm”, relaying the commands to the Viper SmartStart module.

We imagine that the back-end functionality is not unlike the existing SmartStart iOS app, but it looks like [Brandon] beat Viper to the game since Siri has not been made available to 3rd party developers as of yet.

Check out the video below to see Siri in action, then be sure to swing by his web site for additional videos as well as the code that makes this possible.

Sparkfun Announces Free Day 2012

November 23, 2011 by Mike Szczys 22 Comments

We got word that it was coming, and now SparkFun has just announced that Free Day 2012 will take place on January 11th. This is the third time around for the purveyor of goodies for electronic enthusiasts. Each year the offer is a little different, but like in the past you stand to get $100 of free stuff!

The first Free Day back in 2010 saw a lot of hammering which left the SparkFun servers a steaming pile of slag. In 2011 they bolstered their bandwidth handling and tried a quiz-based system for the giveaway. This time around they’re not asking questions but leaving the awards up to chance. Each person has the opportunity to win a $100 credit during the contest window (not specifically announced yet, but definitely starting at 9AM MST on 1/11/2012). There will be some type of bot monitoring, but other than that you can try to claim your credit as many times as you want, with the awards being randomly assigned to a pool of entrants. We recommend you keep an eye on their announcements for more details, but we’ll try to keep this thread updated as we hear more.

Not wanting to wait that long for your components? Don’t miss some of the sales that are going on over this Holiday weekend.

Adventures In Resurrecting A No-name IP Webcam

November 23, 2011 by Mike Nathan 7 Comments

webcam-repair

As many of us do, [Steaky] serves as a kind of on-call help desk for his family. His father in law recently contacted him because his pan and tilt webcam died, and he wanted to see if it could be fixed. Never turning down a challenge, [Steaky] decided to give it a shot.

He ended up having to disassemble it since the camera was completely unresponsive, and what he found inside piqued his interest. The no-name camera sported an ARM microprocessor at its core, and it seems that some of its pins were damaged due to a poorly designed case. He figured resoldering the pins would do the trick, but that wasn’t the end of his adventures.

As he dug deeper into the device, he found that the camera essentially killed itself, reading and writing data to the wrong places due to the damaged pins on the processor. After plenty of searching around, he was able to find a somewhat compatible firmware image, though not everything worked properly.

His father in law was so impressed with his work that he asked for the camera back, even though [Steaky] hadn’t fully repaired it yet. While he bid the camera goodbye, we’re pretty sure he’d be more than happy to reclaim it for a few days if any of our readers had some additional insight or resources that might help him finish the job.

A Doorbell Pleasing To Both The Ears And Eyes

When [David] moved into his new house, one of the things he noticed was that his doorbell was pretty lame. Coming from a home equipped with a solenoid and chime bell, his new wireless solid state doorbell sounded terrible to him.

Crummy sound aside, the doorbell hardly ever worked properly, but alas, other projects cropped up and years went by before [David] addressed his doorbell problem. Like many things that take a long time to come to fruition, we think his resonator bell based solution was well worth the wait.

One of his main goals was to make a nice sounding doorbell that also looked great. He mounted a kid’s resonator bell toy on a sheet of wood, creating his own wooden mallets for the job. He initially had a tough time locating actuators for his doorbell, but found a solution in geared pager motors as featured in another xylophone hack on Make. With the hardware taken care of he focused on the electronics, which consist of a pair of Arduino clones – one on the display and one in his basement.

Stick around to see [David’s] Campanello doorbell in action, and be sure to check out his site for more details if this sounds like something you would like to have in your home.

Power Strip Hack Reduces Standby Electricity Consumption

November 21, 2011 by Mike Nathan 31 Comments

computer-standby-circuit

For years, [Rasmus] has left his computer connected directly to the mains power so that he can turn it on via Wake on Lan. While powered down, it would still continuously consume about 6W of electricity, but now that he didn’t need it to be on standby so often, he wanted to make it more energy efficient.

In Denmark, where he lives, many people use power strips that have an onboard USB cable. These strips are meant to reduce the standby power consumption of PC peripherals such as monitors by powering on the mains sockets only when the computer is active. He decided the easiest way to cut his standby energy consumption to 0W would be to power his computer via this strip as well.

While it sounds great in theory, it presented a sort of chicken/egg problem. If the computer needs to be turned on for the power strip to recognize it, then how could he also supply power to the computer from the same strip? His solution was a small circuit that would charge up while the computer was running, and still hold enough juice to kickstart the PC’s boot process, thus turning on the power strip.

It really is an ingenious way to go about things, nice job!

Black Friday Deals And Contest Giveaways

Winter is coming, and it’s a great time to start accumulating parts and tools to keep you occupied with projects during the dark and cold days ahead.

Black Friday

We got a tip from Pololu about their planned Black Friday deals, and thought we’d check with some of the other parts suppliers that cater to the hobby market too. Here’s what we found:

Adafruit Industries Black Friday – Get 10% off of your purchases made any time on Friday if you use the code ‘BLACK’ (12:00am-11:59pm — we’d guess this is Eastern Time) – UPDATE: Get 10% of Monday 11/28 with the code ‘CYBER’.
Pololu Black Friday – many items are available at a great discount plus extra savings using their Black Friday coupons. Sales run midnight on Thursday morning through 11:59pm on Monday night (Pacific Time, 11/24 through 11/28)
UPDATE: Sugru – we just got an email about a special offer for this moldable material. Now through December 19th you can get your fourth pack for free using the coupon code: YAYCHRISTMAS

We did hear back from SparkFun. They don’t have a Black Friday deal planned, but they are planning on Free Day 2012 happening some time early in the year! We’ll keep our eyes open for details, but if you hear about it before we do send us a tip.

Make also got back to us. No specific details about Black Friday, but we’re told they have some type of deals in the works.

Digikey and Mouser didn’t get back to us in time for this post.

Laser Cutter Giveaways

Do you want a laser cutter to call your own? Yeah, so do we. If you come up with a really cool project perhaps you can win one. It looks like there’s ~~two contests~~ a contest going on right now that is giving one away to the grand prize winner.

Build Lounge is giving away a 40W CO2 Deluxe Hobby Laser Cutter to the best project based on light (community votes).
Instructables – Oops…. we waited too long to post about this one as the contest closed on the 14th, sorry. But chances are good this will come around again. For now, you’ll have to be satisfied at viewing the entries that made the finals.

This Giant Hand Made LED Matrix Must Be Ours!

[Martin] wrote in to share a project his company has been working on for some time, a gigantic 1470 pixel LED wall. The group provides lighting for clubs, parties, etc, and their hand-built LED matrix is always certain to be the hit of the show.

The amazing matrix was designed from the ground up and built by hand in [Martin’s] living room. They designed small 32x32mm “pixel” boards, each of which features 6 PLCC6 RGB LEDs driven by a single WS2801 LED controller. The PCBs were populated by hand and each one was reflowed in a small pizza oven that [Martin] owns. After the pixels were completed, they were attached to aluminum bar and combined to build thirty 70x70cm frames which are connected together to form a giant matrix.

As you can see in the collection of videos below, the display is very impressive. We just hope that they will be compelled to release the schematics for their boards so that we can build one of these in the office.
