A Most Impractical Gear Position Indicator

GPI A few years ago, [Pat] sent in a really nice gear position indicator for his Suzuki V-Storm. With a single seven-segment display , a small microcontorller, and wires tied right into the bike’s ECM, it’s more than enough to do its job, and is much cheaper than aftermarket gear indicators. A simple, elegant solution that does one job well. How could this possibly be any better?

‘Better’ is a relative term, and depending on what you’re optimizing for, a more complex solution can easily be superior. [Pat] figured tripling the value of his motorcycle is a worthwhile goal, so he replaced that seven-segment display with an oscilloscope. It’s the world’s only oscilloscope based motorcycle gear position indicator, and now [Pat] needs a really, really long extension cord.

Like the earlier, more practical version, This build reads the voltage off the bike’s ECM to determine what gear the bike is in. The current gear is then displayed on a Tek MDO3000 with two PWM pins on a microcontroller. Practical? No, but it does look cool. Video below.

ServoBender, The Electronic Pedal Steel

Servo

You’ve most certainly heard a pedal steel guitar before, most likely in any ‘old’ country song, or more specifically, any country song that doesn’t include the word ‘truck’ in its lyrics. Pedal steels are strange devices, looking somewhat like a 10-string guitar with levers that change the pitch of individual strings. Historically, there have been some attempts to put a detuning mechanism for individual strings in normal electric guitars, but these are somewhat rare and weird. [Gr4yhound] just nailed it. He’s come up with the perfect device to emulate a pedal steel in a real guitar, and it sounds really, really good.

The imgur album for this project goes over the construction of the ServoBender in a bit more detail than the video. Basically, four servos are mounted to a metal plate below the bridge. Each servo has a spring and cam system constructed out of 3D printed parts. The detuning is controlled by an Arduino and a few sustain pedals retrofitted with hall effect sensors. Simple, really, but the effect is astonishing.

[Gra4hound]‘s contraption is actually very similar to a B-Bender where a guitarist pushes on the neck to raise the pitch of the B string. This setup, though, is completely electronic, infinitely adjustable, and can be expanded to all six strings. Very, very cool, and it makes us wonder what could be done with one of those freaky robot guitars, a soldering iron, and a bit of code.

Video below, because you should watch it again.

Light Pen Draws on LED Matrix

dot-matrix01

Who needs a 1920×1080 OLED display when you can have an 8×8 matrix of LED goodness? That’s the question [Kathy] asked when she built this LED matrix light pen project. It looks simple enough – a 64-LED matrix illuminates as the pen draws shapes. But how does the circuit know which LED is under the pen? Good old fashioned matrix scanning is the answer. Only one LED is lit up at any time.

[Kathy] used a pair of 74LS138 3-to-8 line decoders to scan the matrix. The active low outputs on the ’138 would be perfect for a common cathode matrix. Of course [Kathy] only had a common anode matrix, so 8 PNP transistors were pressed into service as inverters.

The pen itself is a phototransistor. [Kathy] originally tried a CdS photoresistor, but found it was a bit too slow for matrix scanning. An LM358 op-amp is used to get the signal up to a reasonable level for an Arduino Uno to detect.

The result is impressive for such a simple design. We’d love to see someone use this platform as the start of an epic snake game.

Want customers to stay engaged with your brand? Add music.

GUEST POST

Want customers to stay engaged with your brand? Add music.

This is a response to VentureBeat feature article 4 ways mobile music is becoming the PB&J of the marketing world written by Feed.fm’s Jeff Yasuda.

Every company is trying to build audience, engagement, and retention — all in a never-ending battle to build revenues. Marketers often pray for organic traffic, but many are forced to pay for audience at the top of their conversion funnels. CPI (cost-per-install) continues to increase making it harder to find the magic number for when a customer can be acquired for a price lower than their long-term value.

One of the best new ways to do this that nobody knows about yet? Music. No, really. I’m serious. More specifically, we call it MaaS or Music-as-a-Service, which has proven to be extremely good at boosting engagement — and retention — among customers.

The history of audio marketing goes back decades

In brick-and-mortar settings, music has been used for decades to entice users into parting with their hard-earned dollars. Restaurants, retail stores, and casinos to name a few have been doing this for years though various services such as Muzak and DMX which later became consolidated under the Mood Media umbrella.

Muzak in particular, which was initially known for its painful instrumental renditions of various classic songs like the Girl from Ipanema that would incessantly play in elevators and dentist offices, later became a successful company that amassed over a billion dollars annually in revenue.

Why? Well, it’s because brick-and-mortar businesses like restaurants and clothing stores understand the power that music has on consumer spending. For instance, even certain genres will have different effects on listeners.

Researchers at the University of Leicester in the U.K. found that of the various genres played in restaurants, classical music made diners stay longer at their tables but also had them buying more expensive items. Also, a different study done in a wine store found that when it played French music, more people bought French wines, and likewise for German music. What's even more interesting is that when consumers were asked why the bought a certain wine, they had no idea.

The multi-industry successes of Music-as-a-Service

In our own analysis, we took data from numerous music installations which included games, websites, and apps. In an A/B test environment we found that when music was used, consumers spent on average 433 percent longer using a product than when music was not listened to. In addition, we found that users that listened to music came back to the product 88 percent more on average than those who did not listen to music.

Gaming in particular has been a compelling case for the use of music. We conducted an A/B test on a blackjack game built by an internal game studio at GameSalad. We first drove traffic to the game by advertising on Facebook. After clicking on the ad, the user was dropped on a landing page with a big button that read "Play." Once the user clicked the button, 50 percent of the traffic was sent to a blackjack game that had music playing in the background and 50 percent had no music. The game was identical in both cases and also had standard casino sounds like cards being flipped and chips being collected. The background music that was used for the music variant was a mix of classic rock ranging from AC/DC to Led Zeppelin.

MaaS - Figure 1

The results were staggering with nearly a 350 percent increase in session time and over 170 percent increase in retention. Moreover, it was fascinating to note that over 17 percent of the participants who played the game with music shared on Facebook that they were playing the game and listening to a certain artist.

The table below shows a few key performance indicators that we observed on several thousand unique visitors.

Figure 2

Sins of the past & overcoming misconceptions

While the previously mentioned results were eye-opening, we had several growing pains at the outset.

When Feed.fm launched in the fall of 2013, some of the initial customer discussions focused on how much they hated hearing music on websites. Comments like "When I hear music on a website, I immediately turn it off. That would actually kill engagement, wouldn't it?" were frequent.

We almost immediately needed to explain that the player is an "opt-in" experience and would not auto-play music –- potentially a career damaging or at minimum an embarrassing moment if surfing a website in one's cubicle farm. But after providing enough data and going through specific use cases, customers would end up doing a trial and they’d “get it.” This is part of why its taken music so long to emerge as a powerful marketing platform — and one that didn’t take away from the creativity of the music itself.

The other question we would often get was "I didn't know you could do this… how is this legal?"

We operate under the compulsory statutory license for internet radio. In layman's terms, this means that listeners would not be able to reasonably predict what song is coming next. (Or perhaps a different analogy might be that: the service works more like Pandora, not Spotify.) While I can’t speak for other MaaS operations, our team has gone to great lengths to integrate a compliance engine into our API that manages how many songs from a particular artist or album can be played in a certain time period as well as the number of skips in a user session. We also calculate and report the number of plays to the appropriate copyright agency to insure the artists are properly compensated.

So yes, MaaS is both good for businesses and perfectly legal. And rather than escalating CPI expenditures for attaining new customers (which doesn’t always mean long-term customers), music can boost engagement and loyalty for both new and old customers.

***

Using music to improve the customer experience has been done for decades but using music online to build engagement and retention is a relatively new phenomenon. The audio frontier for marketing initiatives is still a being explored, but it is exciting to see many well-known brands that are beginning to experiment by using music to improve the customer experience and get users to spend money.

Jeff Yasuda is the CEO and Co-Founder of Feed.fm, which provides Music-as-a-Service through its API helping brands, games, and app developers improve session times and retention through major and indie label music.

These motorized roller skates already raised $66K on Kickstarter

These motorized roller skates already raised $66K on Kickstarter

Want to recapture the days when roller skates were considered by some as a primary mode of transportation, but find moving your legs to be a pain in the ass? If so, you might want to check out "RocketSkates."

While no actual rockets are involved (it’s only the early part of the 21st century, you know), these newest incarnations of the classic roller skates have motors and reach 12 mph. Skaters control their speed by tilting backward or forward, and the wheeled wonders wirelessly communicate with each other to ensure they do not cause the skater to perform unwanted motorized splits.

But the momentum of RocketSkates isn't just measured by sidewalk speed. The company that makes the footwear, Los Angeles-based Acton, launched a Kickstarter campaign today with a funding goal of $50,000. By midafternoon, the campaign exceeded that goal, set new stretch goals of $100,000 and $200,000, and undoubtedly have been doing RocketSkate-propelled loop-de-loops in some Californian parking lot.

Of course, motorized skates are like motorized bicycles. Isn’t the idea to have some fun while exercising?

“Who doesn’t want to have fun?” the company’s chief technical officer and founder, Peter Treadway, rhetorically asked VentureBeat. “What we’re trying to do is make a really fun product that made you forget to use your car last week,” he said, after noting that he is a “car guy.”

“We don’t expect people to stop [regular] skating. But if you’re in a car, making these wasteful stops in a 4,000 pound vehicle, here’s a way to engage with the outdoors” and still run, or cruise through, at least some of your errands.

The current incarnation, which has two hub motors in each three-wheeled skate, an onboard microprocessor, and a lithium-ion battery pack that can last up to 90 minutes, has not emerged overnight.

“We’ve been building prototypes, 50 or 60 of them,” Treadway told us. Following earlier, similarly successful Kickstarter campaigns, Acton made an unspecified number of the impossible-to-pronounce spnKiX motorized skates — which required a wireless remote — as well as a motorized scooter.

The newest Acton R RocketSkates, the company points out, are “remote-free” because of the inter-skate wireless communication and the foot-control. They’re also intended to be light enough for walking into Starbucks, rather than having to slow-rev your motors while waiting for your latte.

Battery charges take three hours, and not including the discounts available to pledgers on Kickstarter, the retail prices for the three RocketSkater models is $500, $600, and $700.

Of course, no product these days, even skates, are real products without a smartphone app or a software development kit. The app tracks the skates’ performance and battery, enables the roller to keep in touch with other RocketSkaters, tracks routes and will even show the geometric patterns that the accompanying skates have rollered.

What’s next for this three-year-old company?

Treadway, whose formal background is in industrial design, would only allude to new kinds of “wearable transportation vehicles.”








Virginia senator asks FTC to probe Facebook’s emotional study

Days after the Electronic Privacy Information Center filed a complaint with the Federal Trade Commission about Facebook’s mood-tracking experiment, Sen. Mark Warner (D-Va.) is asking the agency to dig deeper into possible “ramifications” of the social network’s study.

“According to reports it’s not clear whether Facebook users were adequately informed or given an opportunity to opt-in or out,” Warner wrote in a letter to the FTC. “I also have concerns about whether or not Facebook responsibly assessed the risks and benefits of conducting this behavioral experiment as well as the ethical guidelines, in any, that were used to protect individuals.”

He goes on to say that the industry at large could stand to set some standards for future studies. He also thinks the FTC should consider possible oversight measures.

This is the latest response to Facebook’s emotional contagion study, which was recently released in the Proceedings of the National Academy of Sciences. Already the study is under investigation in U.K. and Ireland.

Facebook users and media outlets have also criticized the experiment, and Facebook has struggled to respond to it all. Facebook chief operating officer Sheryl Sandberg offered an apology for not notifying any of the 700,000 participants in the study. But last week Monika Bickert, the company’s global head of policy, called the study “innovation.”

Most recently, EPIC filed a complaint with the FTC, saying Facebook didn’t get consent from any the users it involved in its 2012 study, which violates an order of consent from 2012 and section 5 of the Federal Trade Commission Act regarding “deceptive acts or practices.”

At this point, the debate over the legality and ethics of study is far from over — it’s just heating up.

Here’s the letter from Warner:
