Goodbye Hackaday Subdomains

subdomains-going-away

We’re sure some of you will be sad that the LIFE and HANDMADE Hackaday subdomains are going away. Others will be happy, and many won’t realize they even existed.

We tried a little experiment in diversity this summer, launching the two outliers of our main focus (which is engineering oriented hacks). Each was interesting in their own way, with steady streams of readers and small conversations. But this diverted some of the attention away from what we do best, and that’s why we’re closing them down.

Handmade has already been absorbed. The features which highlighted craftsmanship and artful creations like blowing glass are tangentially interesting. We’ve imported all of the articles and will continue to feature this sort of content from time to time if it fits in with what our readers are normally after.

Life was a little bit outside of what we normally focus on. These sorts of hacks are interesting tidbits to have bouncing around your brain. But you probably won’t see them hitting our front page. Don’t let that discourage you though. If you’ve got a tip or trick to make daily life less mundane you can always let us know on the tips line. At worst we will ignore you. But you might end up seeing it in a Links post, which is our weekly Sunday column that showcases things which weren’t compelling enough for their own post.

Just to be clear for those that are really paying attention. We’re not cramming this content onto the front page with everything else. We’re phasing it out except for those things that go hand in hand with our lust for tech hacks of the highest caliber.

Wireless Marble Labyrinth Uses TI Dev Hardware

wireless-marble-labrinth-using-ti-dev-hardware

There’s so much affordable dev hardware out there these days that you can do a lot without even touching a soldering iron. This is a prime example. Texas Instruments software Engineer [Jordan Wills] recently completed this wirelessly controlled marble labyrinth.

Marble mazes like this are a popular targets for electronic tinkering. We’ve seen smartphones used as the controller, and others that dispense chocolate candy. This time around [Jordan] stuck with the store-bought game to simplify the build. A coworker helped by swapping the two control knobs with servo motors. These interface with a Stellaris Launchpad that has a SensorHub booster pack (shield) and CC2533 radio transceiver module. The same hardware makes up the remote unit as well. This turns the remote into an air mouse by reading the gyroscope, accelerometer, and magnetometer from the booster pack.

He doesn’t specifically mention it in his project log, but we think the magnetometer is used to sync orientation between the base unit and the user remote. Even though the board for the base unit is mounted at 90 degrees compared to how you hold the remote, you should still be able to adjust for the readings in code, right?

Voice Controlled Home Automation Uses Raspberry Pi And LightwaveRF

It’s not quite artificial intelligence, but saying “Jeeves, lights!” will switch on the bulbs in the room. [Chipos81] built the voice-activated home automation around a Rapsberry Pi board with LightwaveRF devices switching lights and outlets.

The LightwaveRF system offers a WiFi link which provides Internet connectivity for all of those devices in your house. This makes it a snap for [Chipos81] to control them from the RPi. To provide speech recognition he’s using CMU Sphinx. It’s an open source speech recognition library developed by researchers at Carnegie Mellon University and released under a BSD license. It seems to do a great job in the video of quickly parsing several sets of commands.

“Jeeves” will even talk back to you to confirm a command. This is generated by Festival, a package developed by the University of Edinburgh.  This provides some entertainment in the last seconds of the video as we detect a distinct Scottish accent when it says “See you tomorrow”.

The GPIO pins provide a bit of feedback, using three colored LEDs to let you know what is going on with the system. There’s even an IR LED used to add voice control to your Television.

Zappo The Robot Mixes Tone Generator, Sensors, Alarm Clock And More

zappo-clock-bot

Now [Kevin] claims he built this robot for his 3-year-old son but we know he just used that as an excuse to spend way too much time in his workshop. The robot is a roundup of all the interesting things you can do with hobby electronics. It’s a great example of what you can teach yourself in one year, as [Kevin] only started tinkering with electronics about fourteen months ago.

The robot centers around an Arduino which manages to control a plethora of auxiliary boards. The alarm clock part of the build has a readout in the center of the robot’s chest. There are a bunch of sounds which can be played as the alarm, including a lot of iconic movie sound bytes. Add to that some playful features — like a tone generator which is altered by the column of potentiometers on the left, motion activated eyes, and sound activated ears — and you’ve got a dream-come-true of a toy for your kid.

As a side note, we wrote this several days ago, but ended up bumping it a couple of times in the publishing schedule. We reached out to [Kevin] to let him know a feature was on the way. When he learned that we bumped it in order to feature [Jamie Matzel’s] giant robot he had to laugh. The two met at a mini Maker Faire about a year ago and that interaction is what gave [Kevin] the confidence to start the project.

Rant: Why I Love What The Chromecast Stands For

I’ve had my hands on this Chromecast for almost a week now and I love it. Years ago I hacked my first Xbox after seeing [Kevin Rose] do it on The Screensavers (I did the hardware mod but that’s inconsequential). Why did I do this? So that I could run Xbox Media Center, the predecessor of XBMC. Since then I’ve dreamed of a device which can be hung on the back of the TV with Velcro and run XBMC. We basically got there with the Raspberry Pi, but the Chromecast is the form-factor that I had always envisioned. This lets me watch Netflix, while the RPi runs XBMC. The two are match made in heaven for under a hundred bucks.

That’s why I love the Chromecast device itself, but the bigger picture is that I love what it stands for. Keep reading to see what i mean.

Google Glass Controlled Quadcopter

google-glass-quadcopter-control

For some reason this project makes us think of the Dog Pog Grid from Neal Stephenson’s Diamond Age. It’s not that there’s a ton of drones floating around this guy, it’s that he’s got one which looks like it’s his bodyguard and is controlled by the Google Glass he wears on his head. The future is now!

We find the metamorphosis of this project interesting as well. It started as a Leap motion controlled rover project. We saw a similar hack just the other day that paired a Leap Motion with a Hexapod. But [Blaine] wasn’t satisfied with that. Having had a taste for alternate control inputs he dug in and got to work making Google Glass the control interface. But the problem with moving your head to control a rover is that you can’t actually see it because looking down would cause unwanted motion. His solution was to transition to a quadcopter, which will hover at eye level when he’s looking right at it. Glass is sending raw sensor data to a server, which does the translation to control commands for the quadcopter.

Pill Dispenser Tattles To The Internet When You Don’t Take Your Pills

pill-taking-reminder-hardware

Here’s another entry in the Parallax microMedic 2013 contest. [Tim] calls it his Propeller-based Internet Logging Pill Dispenser (PDF file), or P.I.L. Box for short.

The hardware is a base unit into which a normal plastic pill organizer is placed. We like this design, as many pharmacies will fill pill boxes for you and this doesn’t complicate that process. You simply pull out the correct box at the beginning of the week and put it in the base unit. You can see one white LED is shining on the Monday slot in the box. This lights up starting an hour before the set pill taking time. This way if you walk by it reminds you. There is also a voice tailor made to scare the elderly that comes out of the speaker, and a simple messages spelled out on the set of seven segment displays. The base unit detects when you press the button to open the pill box and counts that as a properly administered dosage.

Now, if you forget to take the pill it’s not a good thing. The server, which is running on the laptop, will rat you out. It uses the Twitter API to alert whomever is following it — meant for a relative or caregiver — that a dosage was missed. Let’s hope they’re good at keeping up with their Twitter feed!

We remember seeing one other microMedic entry so far, this heart-shaped heart simulator. But we’re going to look around and see how many other good ones we’ve missed.
