Drone-Drone

Posted on by

Yes, the pun was ripped off the article that got our attention . It was just too good not to share. A team of researchers in Japan created an artificial honeybee, a small drone that is meant to cross-pollinate flowers. The (still) manually controlled drone is 4 centimetres wide and weighs only 15 grams. At the bottom side of the drone, a mix of a special sticky gel and horse hair resides. The purpose of this gel is to collect the pollen particles as it bumps into the flowers and exchange it as it goes hopping around from plant to …read more

PiMiniMint — Altoids RPi Zero Computer

Posted on by

We’ve seen our fair share of Altoids mint tin projects and it seems the tin… can always house another interesting project. This time [MWAGNER] managed to make his long time idea of having a computer inside an Altoids tin. He had the idea in 2012, after the original raspberry pi came out, but the size constraints kept the project from going forward. The RPi Zero is much smaller and its launch made the project possible.

[MWAGNER] made two versions, the first version of the PiMiniMint includes a screen, WiFi, Bluetooth, 32GB of storage, an infrared camera, and a full size …read more

PVC Submersible ROV

Posted on by

[mark.brubaker.1] and his crew decided to make a submersible for a school project using PVC pipes as a frame. It has two motors on the back to provide forward thrust and steering as well as a horizontal mounted motor in the middle of the PVC chassis to provide up and down thrust. They used regular motors which they waterproofed by inserting them inside a case full of plumbers wax. We’re not sure how long this will hold at the bottom of the ocean, but it works fine for a school project in the pool. Here’s the instructions on how to …read more

Laser Scanning Microscope

Posted on by

Remember that feeling when you first looked down on a microscope? Now you can re-live it but in slightly different way. [Venkes] came up with a way to make a Laser Scanning Microscope (LSM) with mostly off the shelf components that you probably have sitting around, collecting dust in your garage. He did it using some modified DVD pick-ups, an Arduino Uno, a laser and a LDR.

To be honest, there’s some more stuff involved in the making of the LSM but [Venkes] did a detailed Instructable explaining how everything fits together. You will need a fair dose of patience, …read more

TOBE: Tangible Out-of-Body Experience with Biosignals

Posted on by

TOBE is a toolkit that enables the user to create Tangible Out-of-Body Experiences, created by [Renaud Gervais] and others and presented at the TEI ’16: Tenth International Conference on Tangible, Embedded, and Embodied Interaction. The goal is to expose the inner states of users using physiological signals such as heart rate or brain activity. The toolkit is a proposal that covers the creation of a 3D printed avatar where visual representations of physiological sensors (ECG, EDA, EEG, EOG and breathing monitor) are displayed, the creation and use of these sensors based on open hardware platforms such as Bitalino or OpenBCI, …read more

I’m BatBot

Posted on by

How would you like a bat bot for your next pet drone? Researchers from the University of Illinois at Urbana-Champaign’s Coordinated Science Laboratory and from the California Institute of Technology, created a bat drone. This is not your regular drone; it’s not a styrofoam, bat-shaped, four-propeller kind of drone. It’s a drone that mimics not only the shape but the movement of the bats wings to achieve flight.

The biomimetic robotic platform, dubbed Bat Bot B2, is an autonomous flying robot. The wing mechanics are controlled by a brushless DC motor for the wing flapping along with four wings actuators …read more

Hacking the Aether: How Data Crosses the Air-Gap

Posted on by

It is incredibly interesting how many parts of a computer system are capable of leaking data in ways that is hard to imaging. Part of securing highly sensitive locations involves securing the computers and networks used in those facilities in order to prevent this. These IT security policies and practices have been evolving and tightening through the years, as malicious actors increasingly target vital infrastructure.

Sometimes, when implementing strong security measures on a vital computer system, a technique called air-gapping is used. Air-gapping is a measure or set of measures to ensure a secure computer is physically isolated from unsecured …read more

Pikelet – A Pi-Zero PC

Posted on by

There are many uses for an old 10 Mbps Ethernet hub besides using it as a speed-bump in your network. (No fun in that!) [thinkerzone] decided to gut an old EN104 Bay Networks ‘Netgear Hub’ to re-purpose the solid steel case as a Raspberry Pi Zero PC housing. The project, which [thinkerzone] called Pikelet, aims to be an ‘IoT server’ with the feel of a PC. Note: a PC, not a Gameboy. In his hackaday.io project, he describes the minimum set of features for the Pikelet.

  • Power button – PCs need a power button
  • Power and Status LEDS – Blue

MalDuino — Open Source BadUSB

Posted on by

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 …read more
