Arduino 3D Printed Can Robot (one More Object Avoiding Robot) ​

In this "how to" guide I will show you how to make your own 3D printed Can Robot with the Arduino UNO micro-controller.This is a remake of the Attiny Canbot that I found at by Wingman94 (link here) . I made my own circuit with ATmega328 IC and I add a buzzer to make a beep tone every...

Slow Motion Frame Will Be the New Magic Mirror

[Paul] created a frame that uses an Arduino and LEDs to create a slow motion illusion of a delicate item (like a flower or a feather). The effect is striking as you can see in the video below.

[Paul] had seen similar projects (both one-offs and sold as a product), but wanted to do his own take on it. The principle is simple: The device vibrates the objects at one frequency and strobes LEDs at a slightly different frequency (80 and 79.5 Hz, in this case). The difference between the frequencies (the beat frequency) is what your eye perceives as a very slow (0.5 Hz, here) motion.

Once you know the secret behind the device, it is not very complicated to create. The woodworking for the frame is the bulk of the work. An Arduino excites an electromagnet to vibrate the subject items. It also pulses the LED strips to achieve the strobe effect. It’s simple, striking, and a show piece. It seems like everyone has been building their own magic mirror project, but we proffer this awesome concept as the next big thing everyone should try on their own workbench. Let’s check out a few other examples to get you thinking.

One of [Paul’s] inspirations was Time Frame, which appears in the second video, below. You can find its code on GitHub. It also uses an Arduino to create the same effect. The other inspiration was Slow Dance, which we covered earlier. We’ve also seen a similar trick played with water droplets.

IR thermometer hacked into an IR camera

Using several clever hacking techniques, Niklas Roy can make thermal images using a “simple” thermometer.

True IR (infrared) cameras are still too expensive for many of us, but if you’d just like to know the temperature of something at a distance, IR thermometers aren’t that costly. In theory, if you were to take readings in a grid, color code them, and overlay these readings on an image, you would have a manual IR picture. If you can accomplish this manually, the obvious next step is, why can’t a computer?

Per Roy’s clever hack, yes, this is absolutely possible. His device uses a computer along with an Arduino and two servos to trace a grid with a thermometer. It reads the display at these different points using a webcam, then resolves everything into a nice picture. When overlaid with an actual image, it becomes a low (70 x 44 pixel) resolution thermal image.

MalDuino — Open Source BadUSB

MalDuino is an Arduino-powered USB device which emulates a keyboard and has keystroke injection capabilities. It’s still in crowdfunding stage, but has already been fully backed, so we anticipate full production soon. In essence, it implements BadUSB attacks much like the widely known, having appeared on Mr. Robot, USB Rubber Ducky.

It’s like an advanced version of HID tricks to drop malicious files which we previously reported. Once plugged in, MalDuino acts as a keyboard, executing previous configured key sequences at very fast speeds. This is mostly used by IT security professionals to hack into local computers, just by plugging in the unsuspicious USB ‘Pen’.

[Seytonic], the maker of MalDuino, says its objective is it to be a cheaper, fully open source alternative with the big advantage that it can be programmed straight from the Arduino IDE. It’s based on ATmega32u4 like the Arduino Leonardo and will come in two flavors, Lite and Elite. The Lite is quite small and it will fit into almost any generic USB case. There is a single switch used to enable/disable the device for programming.

The Elite version is where it gets exciting. In addition to the MicroSD slot that will be used to store scripts, there is an onboard set of dip switches that can be used to select the script to run. Since the whole platform is open sourced and based on Arduino, the MicroSD slot and dip switches are entirely modular, nothing is hardcoded, you can use them for whatever you want. The most skilled wielders of BadUSB attacks have shown feats like setting up a fake wired network connection that allows all web traffic to be siphoned off to an outside server. This should be possible with the microcontroller used here although not native to the MalDuino’s default firmware.

For most users, typical feature hacks might include repurposing the dip switches to modify the settings for a particular script. Instead of storing just scripts on the MicroSD card you could store word lists on it for use in password cracking. It will be interesting to see what people will come up with and the scripts they create since there is a lot of space to tinker and enhanced it. That’s the greatness of open source.

You can watch the prototype in action in the video:

The Soda Locker - Vending Machine

Lockers just aren't what they used to be. With so many schools moving to electronic devices for books, lockers become less of a space for your books, and more of a question of: "What am I going to do with this?"What if you could use that space for your own vending machine? In this Instructable, I'l...
