Hacklet #12 – Last Minute Hackaday Prize Submissions

12

If hackers and engineers are notorious for anything, it’s for procrastinating. Many of us wait until the absolute last-minute to get things done. The Hackaday Prize has proved to be no exception to that. Anyone watching the newest projects could see the entries fly in the last few days. Let’s take a quick look at a few.

handuino

[Cyrus Tabrizi] submitted Handuino just a few short hours before the deadline. Handuino is an Arduino based human interface device. You can use it to control anything from R/C cars to 3D printers, to robots to Drones. Input is through the joystick, switches, and buttons, and output through the on-board 2.2″ LCD. Projects can interface to the Handuino via a USB port, or an XBEE radio. Nice Work [Cyrus].

bionicYoSelf

[txyz.info] wants to make us more human than human with Bionic Yourself, an implantable device to make you a bionic superhero. [txyz] plans to use sensors such as an electromagnetic field sensor, accelerometers, and Electromyography (EMG) muscle activity detectors. The idea is to not only sense the implanted wearer, but the world around them. The wearer can then use an embedded Bluetooth radio to send commands. The entire system runs on the Arduino platform, so updating your firmware will be easy. Not everyone has a charging port, so [txyz] has included wireless battery charging in the system.

HAD-alarm-clock[Laurens Weyn] wants to wake us all up with Overtime: the internet connected alarm clock. Overtime is a Raspberry PI powered clock with a tower of 7 segment displays. The prototype displays were sourced from an old exchange rate sign. Overtime does all the normal clock things, such as display the time, and date. It even allows you to set and clear alarms. The display is incredible – there are enough pixels there to play Tetris. Overtime is currently running on an Arduino Mega, but [Laurens] plans to move to a Raspberry PI and hook into the internet for information such as Google calender events.

We’re going to cut things a bit short this week. Your work is done (for now) but for the Hackaday staff, the work is just beginning. We’re already on task, reviewing the entries, and picking which submissions will move on to the next round. Good luck to everyone who entered.

As always, See you in next week’s Hacklet. Same hack time, same hack channel, bringing you the best of Hackaday.io!

Astronaut Or Astronot: Totally Giving Away A Power Supply

Hey! It’s time for another round of Astronaut or Astronot, where we try to give away a jumbo power supply to someone on hackaday.io if they have voted in the most recent community voting round.

Before I get around to telling you who won, we need to go over the criticism of the current voting scheme. There’s a lot of valid criticism out there about how the algorithm that presents projects to the voting page is broken. Yes, it weights projects so some are seen more often than others. And yes, it can be frustrating. However, the results of the voting have no bearing on The Hackaday Prize (the space thing), and the purpose of the entire community voting is to get people looking at the projects, give away t-shirts to the project creators and 3D printers, o-scopes, and power supplies to random people who have voted. We listened to your suggestions and we’re tweaking the algorithm that presents projects for the next round of voting. That starts Monday, we’re doing the drawing on Wednesday, and votes don’t carry over from round to round.

With that out of the way, it’s time to do the whole ‘pick a random person on hackaday.io and see if they voted’ thing. For this week’s lottery, I chose five random people on the site, hoping I wouldn’t go through all of them before giving away a nice bench power supply. The first person, [in3rtial], didn’t vote. You just lost out on a really cool prize there, man.

The second person randomly selected was [tyler]. He voted a total of six times this round. I voted fifty times, but we’re not picky. That means he wins a nice power supply. Everyone go congratulate him for living somewhere that’s cheap to ship a power supply to.

That’s it for this round of Astronaut or Astronot. We’ll have a new round of voting up on Monday. For a change of pace (and because we’re going to be at DEFCON at this time next week), we’re going to do the drawing on Wednesday nevermind, we’re totally doing the drawing from DEFCON. Oh, and if you haven’t, you might want to submit a project to The Hackaday Prize. There’s still time, and your odds of winning something are really, really good.

THP Entry: The Improved Open Source Tricorder

tricorder

Since [Gene Roddenberry] traveled back in time from the 23rd century, the idea of a small, portable device has wound its way through the social consciousness, eventually turning into things like smartphones, PDAs, and all the other technological gadgetry of modern life. A few years ago, [Peter Jansen] started The Tricorder Project, the start of the ultimate expression of [Mr. Roddneberry]‘s electronic swiss army knife. Now [Peter] is building a better, smaller version for The Hackaday Prize.

[Peter]‘s first tricorders borrowed their design heavily from The Next Generation props with a fold-out section, two displays, and a bulky front packed to the gills with sensors and detectors. Accurate if you’re cosplaying, but not the most practical in terms of interface and human factors consideration. These constraints led [Peter] to completely redesign his tricorder, disregarding the painted wooden blocks found on Enterprise and putting all the electronics in a more usable form factor.

A muse of sorts was found in the Radiation Watch, a tiny, handheld Geiger counter meant as an add-on to smartphones. [Peter] envisions a small ~1.5″ OLED display on top, a capacitive sensing wheel in the middle, and a swipe bar at the bottom. Basically, it looks like a 1st gen iPod nano, but much, much more useful.

Plans for what to put in this improved tricorder include temperature, humidity, pressure, and gas sensors, a 3-axis magnetometer, x-ray and gamma ray detectors, a polarimeter, colorimeter, spectrometer, 9-axis IMU, a microphone, a lightning sensor, and WiFi courtesy of TI’s CC3000 module. Also included is something akin to a nuclear event detector; if it still exists, there has been no nuclear event.

It’s an astonishing array of technology packed into an extremely small enclosure – impressive for something that is essentially a homebrew device.Even if it doesn’t win the Hackaday Prize, it’s still an ambitious attempt at putting data collection and science in everyone’s pocket – just like in Star Trek.
