Hackaday Prize Entry: A Sixth Sense

August 13, 2015 by 28 Comments

There’s far more going on in the environment that humans have the senses to detect. Birds migrate with the help of the Earth’s magnetic field, and certain species of fish can detect electrical fields. For his Hackaday Prize entry, [Sebastian] is giving us a sixth sense. He’s building a device that allows anyone to detect the Earth’s magnetic field and find their way north for the summer.

The initial idea for [Sebastian]’s project came after his father’s inner ear was damaged. The doctor told him his brain needed to be trained to work with only one inner ear. If it works for balance, [Sebastian] wondered, why couldn’t the brain be trained to listen to an extra sensory input?

[Sebastian]’s device is an accelerometer and magnetometer, connected to a microcontroller that drives a few vibration motors. By mounting these motors around an ankle strap, [Sebastian] hopes to train his brain to listen to the magnetic fields.

So far, [Sebastian] has a device that can sense the Earth’s magnetic field and buzzes the motor closest to magnetic north. There’s still a lot of work to do, including filtering the magnetometer inputs, adding a ‘sleep’ mode, and putting Bluetooth functionality on board, but it’s already a very well-designed project.

Your Homework For This Weekend

August 13, 2015 by 51 Comments

Your homework for this weekend: Build me something and enter it in The Hackaday Prize. I’m not joking.

It’s very rare for me to come out with a big “ask”, but this is it. I need you now. The Hackaday Prize is our STEAM initiative. It very publicly shows that you can have a lot of fun with engineering in your free time. This is a lesson we need to broadcast and to do so, I want to see dozens of entries come together this weekend.

Here’s the gist of it: Choose a problem that is faced by a large number of people. Build something that helps fix it, and document what you did. You need to start a project, publish 4 project logs, a system design diagram, and a video of less than 2 minutes in length. That’s it, and you can easily be done with all of this if you choose to make this weekend a hackathon.

You may win, you may not. But everyone who posts a project is helping to inspire the next generation of great engineers. The next [Forrest Mims] is out there, lets make sure he or she knows how amazing the world of engineering is! Get to work.

Hackaday Prize Entry: Homebrew Smartwatches

August 12, 2015 by 13 Comments

The Pebble Smartwatch has been around for years, and the introduction of the Apple Watch has everyone looking at wrist-mounted computing as the newest gadget consumers can glom onto. There was never any doubt the 2015 Hackaday Prize would have more than a few smartwatches.

[Ramon]’s Zerowatch gets its name from the Arduino Zero, as this watch is based off of and completely compatible with the Arduino Zero. With a 48 MHz ARM Cortex M0+, a three-axis accelrometer, a microSD card slot, and a bright OLED display, this is an extremely capable wrist-mounted computer. As with all wearable electronics, the enclosure makes or breaks the entire device, and [Ramon] has a very slick 3D printed case for this watch.

Connectivity is important for smartwatches, and that’s something [Montassar]’s Open Source Smart Watch doesn’t skimp out on. He’s using an STM32F4 as the main controller and a 1.44″ TFT, and adding the standard Bluetooth module — an HC-05 — to the mix. [Montasar]’s project is also tackling connectivity by working on a few Android apps that connect directly to this phone. He’s using the MIT App Inventor to speed up development for these phone apps, and makes custom smartwatch apps a breeze.

Both are great projects, and thanks to free, open source, and easy to use tool chains, both projects are excellent examples of open hardware development and a great entry to The Hackaday Prize.

Tonight Is Hacker Chat With The Hackaday Writing Crew

August 12, 2015 by No comments

Tonight at 6pm PDT (UTC-7) is that last Hacker Chat before the entry deadline for the 2015 Hackaday Prize. Join us to talk about all things hardware. Those who need last-minute advice, or are looking for team members for an epic weekend hackathon to bootstrap your winning entry, this is the place to find it. It’s worth entering something… we’re giving everyone with an entry a limited-edition shirt.. and a well executed idea just might get you to the next round!

Joining [Brian Benchoff], [Adam Fabio], and me for tonight’s festivities are [Richard Baguley], [Kevin Dady] (aka [Osgeld]), [Bil Herd], [Kristina Panos], and [Al Williams]. We run these things a bit like the wild-west. There is just a bit of structure, but mostly anything goes. As far as the structure, add your project to this sheet if you want it to be one of the discussion topics. Other than that, share your knowledge and opinions while being excellent to each other. See you this evening!

Hackaday Prize Entry: A Civilization Starter Kit

August 11, 2015 by 43 Comments

Over the last few years, [Marcin] has been working on the building blocks of civilization. He’s busy creating the Global Village Construction Set, the fifty most useful machines ever created. Everything from bread ovens to combine harvesters is part of this Global Village Construction Set, and everything is open source, free for all to use and improve upon.

For this year’s Hackaday Prize, [Marcin] is working on an Open Source Bulldozer. The ability to create earthworks and move dirt around is actually one of humanity’s greatest achievements, and enables the creation of everything from foundations for homes to trans-oceanic canals.

This Open Source bulldozer is astonishingly modular, scaleable from a one-ton microtractor to a 13,000lb dozer, with attachment points for blades, drawbars, and everything else you can attach to a Bobcat earthmover. It’s 168 horses of opensource earthmoving capability, and a perfect addition to this year’s Hackaday Prize.

[Marcin] and his group Open Source Ecology posted a video of this micro bulldozer rolling around on their shop floor recently; you can check that out below. You can also see our coverage of the GLVCS from several years ago.

Hackaday Prize Entry: A Tiny Tool For Car Hacking

August 10, 2015 by 23 Comments

A car from 1940 would have been an almost completely mechanical device. These days though, a car without electricity wouldn’t run. It’s not the engine – it’s the computers; the design details of which automotive manufacturers would love to keep out of the hands of hardware hackers like us. [Mastro Gippo] wanted to build a small and powerful CAN bus reverse engineering tool, and the Crunchtrack hits it out of the park. It’s a CAN bus transceiver, GPS receiver, and GSM modem all wrapped up into a single tiny device that fits under your dash.

[Mastro] has a slight fetish for efficiency and tiny, tiny devices, so he’s packaging everything inside the shell of a standard ELM327 Bluetooth adapter. This is a device that can fit in the palm of your hand, but still taps a CAN bus (with the help of a computer), receives GPS, and sends that data out over cell phone towers.

The device is based on the STM32 F3 ARM microcontroller (with mbed support), a ublox 7 GPS module, and an SIM800 GSM module, but the story doesn’t stop with hardware. [Mastro] is also working on a website where reverse engineering data can be shared between car hackers. That makes this an excellent Hackaday Prize entry, and we can’t wait to see where it goes from here.

Hackaday Prize Entry: Vertical Aeroponics

August 9, 2015 by 32 Comments

For his Hackaday Prize entry, [MIPS ARMSTRONG] is working on an open-source terrarium that will be one of the fastest way to grow foodstuffs or other edible greens. He’s calling it Project EDEN, and it’s shaping up to be one of the most advanced homebrew horticultural devices ever made.

There are a few things that make this indoor greenhouse unique. The most obvious is the incredible number of LEDs used as grow lights. [MIPS] is using 900 Watts worth of Royal Blue and Deep Red LEDs. To water these plants, [MIPS] is taking a cue from NASA and building a High Pressure Aeroponics system – a device that shoots droplets of water only 50 microns in diameter directly onto the roots of the plants.

One of the more interesting aspects of EDEN is the CO2 system. The bulk of plant biomass – like humans – comes from carbon, and plants get their carbon from the atmosphere. Studies have shown that increasing the concentration of CO2 in a grow chamber can increase plant growth. There is a limit before CO2 becomes toxic to plants, so [MIPS] will have to keep a close eye on the CO2 levels with gas sensors.

With high-pressure watering, a CO2 system, and an amazing array of LEDs, this is one of the most advanced homebrew horticulture projects on the planet. It’s also a great fit for this year’s Hackaday prize theme of ‘build something that matters’, and we can’t wait to see [MIPS]’s future developments of his awesome aeroponic terrarium.
