Fun with ESP8266 and WS2812B LEDs

at 12:58 pm. Filed under Cool Gadgets, Crazy Hacks

 

CNLohr has been playing with the popular addressable WS2812B LED lights and the powerful (and cheap) ESP8266. In these videos he discusses how to optimize their usage together and provides full source code to get a foot hold on your own experiments.

Elev-8 Quadcopter Controlled With An Ardupilot Mega Autopilot Build

GlassKNees takes us through the build and what was needed to get this quadcopter working. Upgrading the quad to the APM controller required a few modification such as prop rotation to work, this is just since this is not standardized.

“The GPS/magnetometer are inside the white dome, the telemetry transceiver is the little green circuit board on the left with the antenna pointing down – the board has a clear plastic sheath for protection. I’m using a Spektrum 6 channel receiver mounted to the right of the APM. Power comes from an APM power module that I spliced into the power distribution harness.”

Newport Transporter Bridge

Newport Transporter Bridge_3

 

We drive across bridges all the time and take them for granted. Have a look at this 100 year old Newport Transporter Bridge. The design is absolutely fantastic. Not practical for high volume traffic but for the time this was a very novel solution and it is still operating today.

“The height of the towers is 73.6 metres (241.5 ft), and the height to the underside of the main girder truss above the road level is 49.97 m (163.9 ft). The span between the centres of the towers is 196.56 m (644.9 ft), and the clearance between the towers is quoted as being 180.44 m (592.0 ft); however, including the cantilevered sections, the main girder truss gives the bridge an overall length of 236 m (774.3 ft). The distance between the centres of the anchorage caissons is 471.06 m (1,545.5 ft). Power to propel the transporter platform or gondola is provided by two 35 hp (26.1 kW) electric motors, which in turn drive a large winch, situated in an elevated winding house at the eastern end of the bridge. This winch is sufficient to drive the gondola through its 196.56 m (644.9 ft) total travel at a speed of 3 metres per second.”

Hackers Remotely Hack into Vehicle

at 10:23 pm. Filed under Complex Hacks, Crazy Hacks

 

 Turns out there is a hole in the UConnect entertainment system that can be found in many cars on the road today. This can allow hackers to take control over things like the vehicle systems like acceleration and braking

“Two hackers have developed a tool that can hijack a Jeep over the internet. WIRED senior writer Andy Greenberg takes the SUV for a spin on the highway while the hackers attack it from miles away.”

Old Computer Hardware Instrument Ochestra

Old Computer Hardware Instrument Ochestra

 

There are lots of mechanical computer parts that you can bring to life to make some music. Computer are full of parts that can get this done. This Old Computer Hardware Instrument Ochestra shows us what is possible with some effort.

“This project uses old floppy drives, hard drives, and my 3D printer and uses them to do something they were never designed to do: play in one of the weirdest orchestras ever made.

While there’s currently only 3 types of instruments, the system supports pretty much anything with steppers, or anything that makes a noise on a signal pulse as percussion. An old doorbell, noisy fans, etc. can be used. machines that accept G-code through the standard Serial protocol can be used as well. “

Opening Garage Doors in Seconds using the De Bruijn Sequence

at 10:53 pm. Filed under Complex Hacks, Crazy Hacks

Many garage door openers are not very secure but there are still thousands of codes that need to be transmitted. If these codes were being entered manually it would take a long time to go through all the possibilities but of course we could just use a small processor to run through the combinations. Samy used a kids toy that had all the required hardware to do the task, this could have also been done with a dev board and a small display and a transmitter but it wouldn’t have looked as cool.

The really interesting thing that Samy discovered was how the garage openers look for valid codes, it isn’t a unique entry that is tested. For example if enter the wrong 4 digit code into your home alarm system you would need to wait till it timed out or press a clear key before you attempt a new code. This is not the case with these garage door systems. It just looks at the last X number of bit sequences. The De Bruijn Sequence (here is an online generator to play with) ensures that all sequences can be found within the stream of characters but not in order. This means that the actual amount of data that was needed to be transmitted was less than 5% of the entire regular bruit force test suite.
