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.
If you happen to live near a Micro Center retail store, you are now lucky enough to have another choice when it comes to purchasing DIY electronics components – SparkFun is selling their products at all Micro Center retail outlets.
While it seems SparkFun announced this change in June, we’re seeing quite a bit of buzz on the topic today. We’re pretty sure their entire catalog won’t be available in store, but they are promising a “wide-range of SparkFun products at all 23 Micro Center locations across the country.”
Known for being very DIY-friendly when it comes to building your own PC, Micro Center was a logical choice for SparkFun. There are definitely times when you need/want a part right away rather than waiting for it to ship, so this seems to be an ideal situation for hackers and makers within range of a Micro Center retail store.
This announcement definitely has us wondering if this will be one of the final nails in the Radio Shack coffin. While Micro Center doesn’t have nearly the market penetration Radio Shack does, a wider selection of components and a friendly, knowledgeable staff makes the SparkFun/Micro Center combination is a compelling one.

[Guilherme] picked up a SparkFun Button Pad and was taking a closer look at the device when he noticed that it was based off the ATMega328 microcontroller. Since he loves working with MIDI, he thought that the Button Pad would make a slick yet compact standalone MIDI controller.
Since his ultimate goal was to create a completely standalone controller aside from the power plug and MIDI interface, it forced him to work quite closely with the ATMega chip. He and his partners spent a good deal of time working through some serial communications issues so as not to block the LEDs or MIDI block timer during operation. Ensuring that the Arduino doesn’t block any other functions is obviously important when you are building a MIDI timer, and it seems [Guilherme] was successful in his quest.
The MIDI controller works quite nicely as you can see in the videos below, great job!

[Paul] wrote in to share a project he recently helped assemble, a huge rolling light sculpture with a ton of computer-controlled EL wire circuits. The sculpture recently featured as a float at the Starlight Parade held in Portland, Oregon.
Working alongside the folks from Hand Eye Supply, [Paul] helped design and build all 114 of the float’s electronic circuits. Almost 1000 feet of EL wire was used to light the massive float, all of which was controlled by 15 Sparkfun sequencer boards. The boards ran custom firmware he created in order to communicate with the lighting software that was chosen to run the show.
In the end, the float came out quite nicely, but it was not without its problems during the construction phase. [Paul] ran into tons of issues when using Sparkfun’s EL wire sequencers, and has put together a detailed list of corrections he made to the boards in order to get them working properly.
If you are interested in learning more about the project, you can check out this behind-the-scenes look at the float’s construction.
[Stephen] wrote in to show us this fun LED wall he constructed in his house. He says he was inspired by this project, but found the cost of the BlinkM units from sparkfun to be out of his price range. He really liked how they worked though, so he downloaded the schematic and firmware and built his own. He was able to fabricate 130 of his own for roughly 250 euros as opposed to the 1,452 euro price tag his sparkfun shopping cart had. That’s not a bad deal at all if you’re willing to invest the time in making your own PCBs and assembling the units. You can follow along on his site to see the entire construction process, as well as some pictures of his glass wall in action. The videos, however, aren’t loading for us. Great job [Stephen]!
This is [Pete Dokter], the fourth employee that Sparkfun ever had and currently Director of Engineering there. As you can see, they’re not letting [Peter] come out of his hole. Instead of designing new breakout boards they’ve given him a camera that he’ll be using to record his occasional pontifications. ‘According to Pete’ will become a regularly occuring online show where he answers questions from around the Internets. We’ll admit that the first episode, embedded after the break, is a bit content thin – serving only as an introduction. But we think [Pete] has a pleasant manner and we look forward to what blossoms out of this modest beginning.
We’ve long been fans of engineering-oriented online shows such as [Dave Jones’] EEVBlog, [Bill Hammack’s] The Engineer Guy, A collaboration between [Chris Gammell, Dave Jones, and Jeff Keyzer] call The Amp Hour, [Jeri Ellsworth’s] A-Z Videos and her upcoming series, [Ben Heck’s] The Ben Heck Show…. and we could go on.
With offerings like these you don’t need to wait for traditional TV to transition to IP delivery. Just stop watching crap and start watching these interesting shows.

[sparkfun] announced a new board called the IOIO (pronounced “yo-yo”) this week that allows communication from your Android devices to your upcoming projects.
The board hasn’t been released yet; [sparkfun] is still pulling together documentation and waiting on their first production run. We do know that the board contains a PIC24F MCU, and will give your phone analog input, and Digital I/O, PWM, I2C, SPI, and UART control. Communication with the board is over the USB port on your phone.
The brilliant thing about this board is that an external programmer isn’t required. Everything you connect to this board can be controlled from within Android apps. We covered Android development in a hackaday tutorial series before, so now it’s possible to put these skills to give your projects a touch screen, internet and bluetooth connections, a camera, or your phone’s accelerometers. Very slick.
Video of some basic functions demonstrating what possible with this board after the jump, but feel free to comment and tell us what you’d like to see done with this board.
