Hard Drive Clock is Simple and Elegant

Binary hard drive clock

[Aaron] has been wanting to build his own binary desk clock for a while now. This was his first clock project, so he decided to keep it simple and have it simply display the time. No alarms, bells, or whistles.

The electronics are relatively simple. [Aaron] decided to use on of the ATMega328 chips he had lying around that already had the Arduino boot loader burned into them. He first built his own Arduino board on a breadboard and then re-built it on a piece of protoboard as a more permanent solution. The Arduino gets the time from a real-time clock (RTC) module and then displays it using an array of blue and green LED’s. The whole thing is powered using a spare 9V wall wort power supply.

[Aaron] chose to use the DS1307 RTC module to keep time. This will ensure that the time is kept accurately over along period of time. The RTC module has its own built-in battery, which means that if [Aaron's] clock should ever lose power the clock will still remember the time. The RTC battery can theoretically last for up to ten years.

[Aaron] got creative for his clock enclosure, upcycling an old hard drive. All of the hard drive guts were removed and replaced with his own electronics. The front cover had 13 holes drilled out for the LED’s. There are six green LED’s to display the hour, and seven blue LED’s for the minute. The LED’s were wired up as common cathode. Since the hard drive cover is conductive, [Aaron] covered both sides of his circuit board with electrical tape and hot glue to prevent any short circuits. The end result is an elegant binary clock that any geek would be proud of.

The Small & Cheap miniSpartan6+

FPGA

There have been quite a few boards put out in recent months with an FPGA, some RAM, Flash, and a bunch of I/O, the working theory being FPGAs are the new hotness, ready to steal the crown from Arduino and put a programmable logic development board in the hands of millions. We’re not so sure that’s going to happen. but Scarab Hardware’s miniSpartan6+ board does look pretty nice, and has more than enough on board to serve as anyone’s first FPGA platform. It’s also one of the first FPGA boards we’ve seen that is breadboard friendly. Nice touch.

This tiny board features a Spartan6 LX9 FPGA, with just under 10,000 logic cells. An FPGA platform is useless without some sort of IDE, so the Scarab Hardware folks have taken the Mojo IDE, improved the GUI, added a few libraries, and rolled everything up into a ‘not the Arduino IDE, but as simple and better’ platform.

Right now, the crowdfunding campaign for the miniSpartan6+ is well over 200% funded with a little less than a month to go. The stretch goals the team have in mind – a very likely probability, given what they’re asking – include a faster FPGA, a higher resolution ADC, and support for HDMI input and output. That last bit – HDMI input – will allow anyone to do some cool things like overlaying video with HDMI for a pretty reasonable cost.

Tennis Ball Launcher Has Puppies Running the 100m Dash

Launching Tennis Balls with Ease

[Brian] from 24 Hour Engineer has a friend with arthritis who can’t easily play ball with his new puppy — so [Brian] stepped in and built him this awesome tennis ball launcher.

You see, most tennis ball launchers require a solid flick of the wrist, and since just plain old throwing it is out of the question too, [Brian] had to make him something powerful and easy to use. After sketching out some designs he came up with the basic concept that eventually became what is pictured above.

The frame is made of 2″ PVC pipe, which serves two purposes, support, and safety. The bungee cord launching system is actually contained within the pipe, keeping it out of the way, and free from catching on anything during firing. A pair of pulleys mounted at the cord opening ensure the cord doesn’t wear out.

What we really like is the trigger mechanism [Brian] made out of some carefully cut wood,  a steel corner brace and a few nuts and bolts. It’s a simple mechanism that provides leverage and an easy way to release the bungee cord. 

Now we know what you’re all thinking — how is a guy with arthritis suppose to load this thing? Well, it’s actually foot loaded: stand it up straight, put your foot on the ball harness, and step down until it clicks into the trigger mechanism. It’s similar to loading a crossbow backwards… which you would never do for obvious reasons. Still, we feel the tennis ball has rather low risk associated with it compared to a sharpened steel bolt…

If you want to build your own, [Brian's] laid out everything you need to know on his site, with plans to turn it into an Instructable at some point — there’s even more info via his build log.

You could also build an electric version if you’re feeling particularly lazy.

iFind is the world’s first battery-free location tag

iFind is the world's first battery-free location tag

How can you leverage mobile to increase profitability for your company? Find out at MobileBeat, VentureBeat's 7th annual event on the future of mobile, on July 8-9 in San Francisco. Register now and save $200!

iFind is a battery-free item location tag. It helps you ease the pain by saving you the time and frustration of trying to locate your misplaced item. Plus, your brain is also liberated from intense thoughts of "where did I last put it?"

Item-locating hardware devices like iFind aim to aid you in the misadventure of finding your misplaced items. Most of these work by connecting to an app on your mobile phone.

However, what makes iFind stand out from the crowd is that it requires absolutely no battery to function.

Developed by WeTag, iFind collects its power from ambient electromagnetic sources, such as Wi-Fi transmitters or mobile phone antennas. The power attained can be converted into enough electrical currents and stored in a power bank in iFind, which simulates a battery that continually supports a Bluetooth 4.0 Low Energy (BLE) radio.

ifind location

You simply turn on the Bluetooth on your mobile phone and connect to iFind, download the iFind app, and enter the tag ID to start enabling location tagging.

In the case of misplacing your item tagged with iFind, open up the iFind app on your mobile phone to start locating the item. The tag would then let off a  beeping sound upon detection.

And, if you lose your phone, no worries. Shake the iFind tag and your mobile phone will ring. It goes both ways!

iFind comes in a dainty, square-ish tag about an inch square and 2.4mm thick with various stylish colors for users to choose from. The maximum range from your mobile phone to the tag is approximately 60 meters within line of sight, or 50 feet, depending on the environmental conditions.

iFind tag

The WeTag team spent one good year developing iFind, and the results have been rewarding. Since its first launch on Kickstarter, the team has raised more than $200,000. The first shipment of iFind tags can be expected in October this year.

SoundCloud’s new office in Berlin puts yours to shame

SoundCloud's new office in Berlin puts yours to shame
Image Credit: SoundCloud

On Wednesday, Berlin's The Factory opened (more on the opening) its 16,000 square-meter startup office. While all the other startups (such as 6Wunderkinder, Mozilla, Zendesk, and others) are still waiting to finally move into Berlin's new startup space, SoundCloud's office is the only one that is ready.

It spreads over three stories and has space for more than 170 people. Each conference room has a different neighborhood, and all are named after areas of the cities SoundCloud has offices in. One level has Berlin's districts Mitte and Kreuzberg. The other level has rooms named after districts in London, New York and San Francisco.

A special room in this office is SoundCloud's very own recording studio. "Many of our employees record their own music. We want to offer them to do so in here to get the best results and express their musical creativity," says Kelly Robinson, who designed the office in cooperation with Kinzo Berlin.  "The recording room also leaves many options for events and community purposes," she adds.

Also very cozy is the nap room. "With many people flying around through the different offices, they are often jetlagged when they get here. Here they can rest." They put candles in the room as a sign. "If they are not lit, people can come in and work in silence. If a candle is lit, they know someone is asleep."

"Our headquarters in Berlin gives the basic idea and tonality we want for our office around the world," says Robinson. She adds that this project took overall more than two years.

"The office space is just as much a long-term project as SoundCloud itself," David Noël, VP Community at SoundCloud explained. "I told myself that if I ever have a bad day or don't want to go to the office, I should leave the company," he stated.

Noël has been with SoundCloud since it was founded five years ago and says the secret of staying motivated is to see the big picture and the long term achievements. For SoundCloud that means to improve the user experience, get more users on board and answer questions about how to deal with mobile challenges as a streaming platform.

SoundCloud does not share any user numbers. It does, however, state that with every minute 12 hours of sound are created on the platform. By focusing on creating content, SoundCloud differs to other platforms such as Spotify or Beats Music, but sure enough faces the same questions, e.g. how to be profitable.

When asked if a monthly model such as Spotify’s would be an option, Noël explained that SoundCloud looks at many options and models but has no concrete answer yet. Noël explained that the Pro Accounts (between €29 and €99) give extra features such as extended statistics to users who upload acoustic content and are popular.

The company will keep growing and, therefore, has an additional 400 square meters to take up within The Factory, as well as further space in an additional smaller building on The Factory's site. As SoundCloud is focusing on the mobile experience, it is currently hiring.

The 2,910 square-meter SoundCloud HQ is absolutely worth a visit. SoundCloud knows so and plans on doing office tours for those interested once a month.

Next time you’re in Berlin, make sure not to miss the chance.

Repurpose an Old CRT Computer Monitor as a High Voltage Science Project Power Supply

High Voltage Monitor Power Supply Conversion

Finally somebody has found a good use for all those old CRT computer monitors finding their way to the landfills. [Steven Dufresne] from Rimstar.org steps us through a very simple conversion of a CRT computer monitor into a high-voltage power supply. Sure you can make a few small sparks but this conversion is also useful for many science projects. [Steve] uses the monitor power supply to demonstrate powering an ionocraft in his video, a classic science experiment using high voltage.

The conversion is just as simple as you would think. You need to safely discharge the TV tube, cut the cup off the high voltage anode cable and reroute it to a mounting bracket outside the monitor. The system needs to be earth grounded so [Steve] connects up a couple of ground cables. One ground cable for the project and one for a safety discharge rod. It’s really that simple and once wired up to a science project you have 25kV volts at your disposal by simply turning on the monitor. You don't want to produce a lot of large sparks with this conversion because it will destroy the parts inside the monitor. The 240K Ohm 2 watt resistor [Steve] added will help keep those discharges to a minimum and protect the monitor from being destroyed.

Yes this is dangerous but when you’re working with high-voltage science experiments danger is something you deal with correctly. This isn’t the safest way to get high-voltage but if you have to hack something together for a project this will get you there and [Steve] is quite cautious including warning people of the dangers and how to safely discharge your experiment and the power supply after every use. This isn’t the first high-voltage power supply that [Steve] has constructed; we featured his home-built 30kV power supply in the past, which is a more conventional way to build a HV power supply using a doubler or tripler circuit. Join us after the break to watch the video.

The Worst E-Reader Ever

oled

Over on the Projects site, [Jaromir] has created a tiny device with an OLED display, three buttons, and a USB port for storing text files, be it for saving a shopping list, a cheat sheet, or the most unusable e-reader ever made.

The front of the device is simply a 96×32 pixel OLED and three buttons for ‘up’, ‘down’, and ‘open/close’. The reverse side is where the magic happens with a PIC24 microcontroller that sets up a file system on the chip, allowing [Jaromir] to write 64kB of data on what is actually a Flash drive with a pitiful capacity. Text files are viewable on the OLED, with the video below showing the front page of Wikipedia being displayed in a glorious 16×4 text mode.

It’s not a very useful device by any means, but for some reason it’s garnered a lot of skulls and followers over on Hackaday Projects. In response to that, [Jaromir] is working on version two with a new PCB and a design for a 3D printed case. Not bad for what [Jaromir] himself describes as worse than just about any phone or tablet.

Thanks, Elon Musk, for being a real leader on patent reform

Thanks, Elon Musk, for being a real leader on patent reform

Fred Wilson beat me to it this morning with his post A Big Win For The Patent Reform Movement but he's got a couple of hour time zone advantage over me. Regardless, I love Fred's punch line:

So it was with incredible joy that I read these words by Elon Musk, founder and CEO of Tesla Motors and possibly the most innovative entrepreneur in the world right now. [Elon wrote in his post All Our Patent Are Belong To You] "Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters. That is no longer the case. They have been removed, in the spirit of the open source movement, for the advancement of electric vehicle technology."

I'll pile on with my accolades to Elon. While I don't know him, I'm long time friends with his brother Kimbal, who lives in Boulder, so I always feel like I get a little taste of Elon whenever I talk to Kimbal.

So, Elon, thank you for being a real leader here and taking action. I've been asserting for a number of years that while software patents are completely fucked up, the general patent system stifles innovation.

More and more research is appearing on software patent issues and patent trolls in general, including this recent piece by Catherine Tucker, an MIT Sloan professor of Marketing, titled The Effect of Patent Litigation and Patent Assertion Entities on Entrepreneurial Activity. As Ars Technica summarizes in its article, New study suggests patent trolls really are killing startups:

Turns out there is a very real, and very negative, correlation between patent troll lawsuits and the venture capital funding that startups rely on. A just-released study by Catherine Tucker, a professor of marketing at MIT's Sloan School of Business, finds that over the last five years, VC investment "would have likely been $21.772 billion higher… but for litigation brought by frequent litigators."

As my lawyer friends tell me, "the Supremes" are finally making some calls on this. The induced infringement theory, a particularly obnoxious patent litigation approach, is no longer valid. The main event, Alice Corp. v. CLS Bank, is still waiting to be ruled on. Let's hope the Supremes take a real stand on when software claims are too abstract to be patented this time around, unlike the punt they made on Bilski.

Cantor’s loss won’t kill immigration reform. It was already dead

Cantor's loss won't kill immigration reform. It was already dead

There are debates about whether comprehensive immigration reform is dead because of the defeat of House Majority Leader Eric Cantor (R-Va.) in the primaries. The fact is that it never had any hope. Americans are deeply divided on whether people who entered the country unlawfully should be allowed to become citizens and enjoy the same rights as those who were born here or migrated legally. The insistence by the Democrats on mandating a path to citizenship for the undocumented has turned the legislation into a poison pill that the Republicans will not swallow.

True, the Senate's bill created only a narrow and treacherous path to citizenship. But it allowed opponents of immigration reform to claim that it was an amnesty. A survey of registered Republicans conducted by FWD.us from May 17-23 revealed that Americans overwhelmingly believe that the immigration system is broken and that Congress should take immediate action to fix it, with Republicans being most convinced that immediate action is necessary. As well, the majority of Americans support of some kind of legalization for undocumented immigrants — they don't believe that they can or should be deported.

But there is a strong countervailing sentiment that undocumented immigrants should not be granted amnesty. The debates over citizenship pushed many Americans who would otherwise support some form of legalization for the undocumented, over the edge.

Comprehensive immigration reform may well be dead; immigration reform need not be. Our political leaders need to package up small pieces of legislation that are acceptable to the majority of Americans and allow both sides of the political spectrum to declare victory.

One way of resolving the issue of the undocumented workers, for example, is to immediately provide them with temporary visas that allow them to work in the United States, pay taxes, and return home to visit their relatives. They need these rights more than they need the right to vote — which is what the Democrats have been insisting on. Note that from the last immigration-reform measure, in 1986—which provided amnesty to the undocumented—only 40 percent who qualified became U.S citizens. In other words, the majority chose not to take the path to citizenship that is creating the toxic debates, and we can meet the major concerns of all sides by setting the subject of citizenship aside in favor of addressing the needs of the people we are trying to help.

Most Americans would also support providing basic human rights—and citizenship—to the 1.8 million children whose undocumented parents brought them to this country to give them a better future. These children grew up as Americans, believing they were entitled to the same rights and freedoms as their friends are. But, because they don't have the proper paperwork, they are forced to live in the shadows of society, with limits on where they can work and study and on what they can do. There has been broad support on both sides of Congress for the DREAM Act—which would provide for their human rights. Reaching consensus on this shouldn't be very hard.

On the skilled-immigration front, there are also many points of agreement—such as on a startup visa, which would allow foreign entrepreneurs to set up shop in the United States, to boost innovation, and to create jobs. By the Kauffman Foundation's estimate, this visa would create as many as 1.6 million jobs and boost the nation's annual gross domestic product by 1.6 percent within 10 years.

An increase in the number of permanent-resident visas for foreign doctors, scientists, and engineers would also receive broad support. After all, there are severe shortages, in certain parts of the country, of doctors and nurses to provide medical care, and Silicon Valley lacks qualified engineers and software developers.

Broad consensus could also be achieved on providing temporary work visas for unskilled workers in non-farm jobs, such as in hospitality, food processing, construction, cleaning, and maintenance. ImmigrationWorks USA's president, Tamar Jacoby, says that in every year from 2003-09, more than 350,000 low-skilled foreigners came to the United States illegally to do this work, and that the only way to prevent future illegal immigration is to create a legal way to meet the continuing demand. Programs such as this could be expanded in good economic times and shrunk in bad times.

Unnecessary battles over immigration have stymied the United States for too long. The country is bleeding competitiveness, and people are needlessly suffering, merely because we have lacked the imagination to see that immigration reform is not all or nothing. Let's start by doing the things that we agree on and give the nation a victory.
