DIY Rubber Ducky is as Cheap as its Namesake

Posted on by

The “Rubber Ducky” by Hak5 is a very powerful tool that lets the user perform rapid keystroke injection attacks, which is basically a fancy way of saying the device can type fast. Capable of entering text at over 1000 WPM, Mavis Beacon’s got nothing on this $45 gadget. Within just a few seconds of plugging it in, a properly programmed script can do all sorts of damage. Just think of all the havoc that can be caused by an attacker typing in commands on the local machine, and now image they are also the Flash.

But unless you’re a professional …read more

Simple RC to USB Interface

Posted on by

With the radio control hobby arguably larger now than it ever has been in the past, there’s a growing demand for high-fidelity PC simulators. Whether you want to be able to “fly” when it’s raining out or you just want to practice your moves before taking that expensive quadcopter up for real, a good simulator on your computer is the next best thing. But the simulator won’t do you much good if it doesn’t feel the same; you really need to hook your normal RC transmitter up to the computer for the best experience.

Unlocking 12V Quick Charge on a USB Power Bank

Posted on by

[Robert Nixdorf] frequently needs to use this high-end audio recorder, but it sucks dry a set of eight AA batteries in just a few hours. Obviously a longer lasting solution was required, and he started scouring the web looking for an answer. He bought a Quick Charge power bank and then hacked a Digispark to negotiate with the power bank to provide 12V output to Quick Charge his audio recorder.

Qualcomm’s Quick Charge system is designed to provide increased output voltages to reduce charging time in QC compatible devices such as mobile phones powered by their Snapdragon range of SoC’s. …read more

Another Desktop LED Xmas Tree!

Posted on by

We love it when someone takes inspiration from one of our posts and comes up with their own twist on it. [Matthew] liked one builds he saw on Hackaday so much, he built his own LED desktop Xmas tree!

[Matthew] was inspired by [designer2k2]’s DIY desktop Xmas tree that was posted in October. To get started, he found a set of concentric WS2812 rings over on Ali Express. The five rings total 93 LEDs, plus a single WS2812 for the top of the tree. He also got a laser cut tree model from Thingiverse and had it cut, combining the …read more

Just In Time For Christmas! A DIY Desktop LED Tree

Posted on by

Okay, we haven’t even hit Halloween yet, but if you’re planning some kind of holiday project, now’s a good time to start ordering your parts, especially if you’re designing your own PCB. While there’s no PCB involved, [designer2k2] built a desktop “hollow” Christmas tree using some WS2812 RGB LEDs controlled by a microcontroller and powered by USB.

The board running [designer2k2]’s project is a Digispark, a USB powered board by Digistump which contains an ATtiny85. The LEDs, four different sized NeoPixel rings, plus a single pixel for the top, are connected together using some solid wire which makes for a …read more

Hackaday Prize Entry: A Better Way Of Cheating

Posted on by

Believe it or not, some video games are still developed for the PC. With video games come cheat codes, and when they’re on the PC, that means using a keyboard. You can easily program any microcontroller to send a string of characters over a USB port with the touch of a button. Believe it or not, a lot of people haven’t put these two facts together. [danjovic] has, leading him to build a simple and cheap USB keystroke generator for quickly typing in cheat codes.

[danjovic] is basing his build around a Digispark, a cheap, USB-enabled ATtiny85 dev board. This, …read more
