Don’t Forget Your Mints When Using This Synthesizer

Posted on by

While synthesizers in the music world are incredibly common, they’re not all keyboard-based instruments as you might be imagining. Especially if you’re trying to get a specific feel or sound from a synthesizer in order to mimic a real instrument, there might be a better style synth that you can use. One of these types is the breath controller, a synthesizer specifically built to mimic the sound of wind instruments using the actual breath from a physical person. Available breath controllers can be pricey, though, so [Andrey] built his own.

To build the synthesizer, [Andrey] used a melodica hose and …read more

Looking at Wind Turbines From a Different Angle

Posted on by

When we think of wind turbines, the first thing that usually comes to mind is the typical Sim City-esque type – 3 blades, gigantic, and wired into the municipal power grid. In truth, the world of wind power generation is far more varied indeed – as [Vittorio]’s vertical-axis wind turbine shows us.

So what exactly is a vertical-axis wind turbine, you ask? Well, rather than the typical setup with blades rotating about a horizontal axis, as in typical utility turbines or a classic electric fan you might use to cool off on a sunny day, instead a vertical axis is …read more

Modernizing Puerto Rico’s Grid

Posted on by

After two massive hurricanes impacted Puerto Rico three months ago, the island was left with extensive damage to its electrical infrastructure. Part of the problem was that the infrastructure was woefully inadequate to withstand a hurricane impact at all. It is possible to harden buildings and infrastructure against extreme weather, and a new plan to restore Puerto Rico’s power grid will address many of these changes that, frankly, should have been made long ago.

Among the upgrades to the power distribution system are improvements to SCADA systems. SCADA allows for remote monitoring and control of substations, switchgear, and other equipment …read more

Hackaday Prize Entry: Modular, Rapid Deployment Power Station

Posted on by

After a disaster hits, one obvious concern is getting everyone’s power restored. Even if the power plants are operational after something like a hurricane or earthquake, often the power lines that deliver that energy are destroyed. While the power company works to rebuild their infrastructure, [David Ngheim]’s mobile, rapid deployment power station can help get people back on their feet quickly. As a bonus, it uses renewable energy sources for power generation.

The modular power station was already tested at Burning Man, providing power to around 100 people. Using sets of 250 Watt panels, wind turbines, and scalable battery banks, …read more

Typhoon-proof Wind Turbine

Posted on by

While wind energy is rapidly increasing its market share across the world, wind turbines are not able to be constructed everywhere that they might be needed. A perfect example of this is Japan, where a traditional wind turbine would get damaged by typhoons. After the Fukushima disaster, though, one Japanese engineer committed himself to building a turbine specifically for Japan that can operate just fine within hurricane-force winds. (YouTube, embedded below.)

The “typhoon turbine” as it is known works via the Magnus effect, where a spinning object directs air around it faster on one side than on the other. This …read more

The Engineering That Survives Hurricanes

Posted on by

Florida is a great place to live, especially around January when it’s sunny and 24 degrees outside (76F) while all of your friends from back home are dealing with scraping ice off of their windshields every morning. In the late summer, though, this pleasant tropical paradise can sometimes take a turn for the worse, because Florida is one of the handful of places that frequently see some of the worst storms on the planet: hurricanes. As a Floridian myself, perhaps I can shed some light on some of the ways that the various local governments and their residents have taken …read more

DIY Wind Turbine for Free Energy

Posted on by

With electricity cost going up and the likes of British Gas hiking up their price, everyone could use a bit of free energy. There are a number of ways to harvest renewable energy including solar and wind, however, the cost of setting up a wind farm can be quite high. [Mr Tickles] has uploaded a video where he has a cheaper DIY method of making a DIY wind turbine.

His project uses a commercial ceiling fan as a turbine for converting the wind energy into electricity. PVC pipes are used to mount the entire thing such that it becomes portable. …read more

The Most Straightforward Wind Turbine

Posted on by

We can all use a little more green energy in our lives at home. So when [ahmedebeed555] — a fan of wind power — ran into durability troubles with his previous home-built turbine, he revised it to be simpler than ever to build.

Outside of the DC generator motor, the rest of the turbine is made from recycled parts: a sponge mop sans sponge, a piece from an old CD drive case acting as a rudder, the blades from a scrapped fan, and a plastic bottle to protect the motor from the elements. Attach the fan to the …read more

Hacking Into…. A Wind Farm?

Posted on by

Pick a lock, plug in a WiFi-enabled Raspberry Pi and that’s nearly all there is to it.

There’s more than that of course, but the wind farms that [Jason Staggs] and his fellow researchers at the University of Tulsa had permission to access were — alarmingly — devoid of security measures beyond a padlock or tumbler lock on the turbines’ server closet. Being that wind farms are generally  in open fields away from watchful eyes, there is little indeed to deter a would-be attacker.

[Staggs] notes that a savvy intruder has the potential to shut down or cause considerable — …read more
