Fizyczne lokalizacje ~800000 samochodów elektrycznych dostępne były ~publicznie. Terabajty danych. Jak do tego doszło?

Jak czytamy w prezentacji niemieckich badaczy: 1. Udało się odnaleźć „ciekawą domenę” (adres internetowy), używaną przez jedną ze spółek grupy Volkswagen (narzędzie: subfinder) 2. Na tej domenie badacze wykonali atak 'bruteforce’ na dostępne tam publicznie katalogi/pliki (narzędzie: feroxbuster lub gobuster) 3. Odnaleźli tam pozostawioną „konsolę debug” – czyli /actuator/heapdump❗ 4....

Today, the KNX actuators are being replaced because they smell strange and occasionally emit smoke after the overvoltage damage.

Looks nice with the sunrise!

After removing an actuator, it doesn't look as nice anymore, but in the end, everything shines like new again.

Of course, you can use different to actions.

Each or is like its own small that sends telegrams via a two-wire bus line. Each is also assigned a physical address, basically like an IP address.

`Here we report a theoretical and experimental framework for the force behaviour in generic solid/liquid-dielectric stacks independent of design and solely based on their properties. We use this model to develop -based solutions, which rely on matching the bulk charge relaxation rates of the constituent dielectrics, for a variety of soft actuator systems: tunable , artificial and .`

Working Model Reveals Amazing Engineering of Webb’s Mirror Actuators

We end up covering a lot of space topics here on Hackaday, not because we're huge space nerds -- spoiler alert: we are -- but because when you've got an effectively unlimited budget and a remit to make something that cannot fail, awe-inspiring engineering is often the result. The mirror actuators on the James Webb Space Telescope are a perfect example of this extreme engineering, and to understand how they work a little better, [Zachary Tong] built a working model of these amazing machines.

The main mirror of the JWST is made of 18 separate hexagonal sections, the position of each which must be finely tuned to make a perfect reflector. Each mirror has seven actuators that move it through seven degrees of freedom -- the usual six that a Stewart platform mechanism provides, plus the ability to deform the mirror's curvature slightly. [Zach]'s model actuator is reverse-engineered from public information (PDF) made available by the mirror contractor, Ball Aerospace. While the OEM part is made from the usual space-rated alloys and materials, the model is 3D printed and powered by a cheap stepper motor.

That simplicity belies the ingenious mechanism revealed by the model. The actuators allow for both coarse and fine adjustments over a wide range of travel. A clever tumbler mechanism means that only one motor is needed for both fine and coarse adjustments, and a flexure mechanism is used to make the fine adjustments even finer -- a step size of only 8 nanometers!

Hats off to [Zach] for digging into this for us, and for making all his files available in case you want to print your own. You may not be building a space observatory anytime soon, but there's plenty about these mechanisms that can inform your designs.

Thanks to [Zane Atkins] for the tip.

3D Printed Absolute Encoder is Absolutely Wonderful

When you need to record the angle of something rotating, whether it's a knob or a joint in a robotic arm, absolute rotary encoders are almost always the way to go. They're cheap, they're readily available, and it turns out you can make a pretty fantastic one out of a magnetic sensor, a ziptie, and a skateboard bearing.

When [Scott Bezek] got his hands on a AS5600 magnet sensor breakout board, that's just what he did. The sensor itself is an IC situated in the middle of the board, which in Scott's design sits on a 3D-printed carrier. A bearing mount sits atop it, which holds -- you guessed it -- a bearing. Specifically a standard 608 skateboard bearing, which is snapped into the mount and held securely by a ziptie cinched around the mount's tabs. The final part is a 3D-printed knob with a tiny magnet embedded within, perpendicular to the axis of rotation. The knob slides into the bearing and the AS5600 reads the orientation of the magnet.

Of course, if you just wanted a rotary knob you could have just purchased an encoder and been done with it, but this method has its advantages. Maybe you can't fit a commercially-available encoder in your design. Maybe you need the super-smooth rotation provided by the bearing. Or maybe you're actually building that robotic arm -- custom magnetic encoders like this one are extremely common in actuator design, and while the more industrial versions (usually) have fewer zipties, [Scott]'s design would fit right in.
