"Ghost Gunner is a non-profit open source hardware effort by Defense Distributed. Ghost Gunner builds on the open source community’s existing hard work, including the gshield 3 axis motion hardware, the grbl g-code parser and motion controller, and the legendary Arduino microcontroller. All GhostGunner schematics and design files will be published into the public domain."

"I built this laser cutter after being inspired by [a project I saw] and the design is almost identical, there for I will not go into details about my build but will instead focus on what you can do with it."

"This article shows roughly what I’m intending to build and my concept of core functionality. Building the frame/stilts out of Plywood. Starting work on the hands so I can size the forearms and arm frame assembly. Building the Forearm mechanism with opening weapon pod. Working my way up the arm and building the shoulder mechanisms….and more…"

"We all are very familiar with Printed Circuit Boards or PCBs as they are easily found in television sets, computers and in every electronic device. PCB is widely accepted and most commonly used in Electronics industry. PCB is very cost effective, it assembles the complex circuits in small space and eliminates the risk of loose connections, it has pre designed copper tracks to connect the components in effective and clean way."

"Prankophone is a sound object being a hybrid of synthesizer, telephone and logic module. The main principle of the object’s functioning is as follows: depending on the current mode, the apparatus calls to random or pre-defined recipients and plays them algorithmic melodies created from their phone numbers. The speakers transmit both the synthesized sounds and the sound from answering person."

"Voltage Multipliers are the circuits where we get very high DC voltage from the Low AC voltage supply, a voltage multiplier circuit generates voltage in multiple of peak input voltage of AC, like if the peak voltage of AC voltage is 5 volt, we will get 15 volt DC at the output, in case of Voltage Tripler circuit."

"Hardware setup is pretty easy for this, it’s nothing compared to what you’ve just done for the Nerf gun. Grab your breadboard, plug in your Bluetooth module (assuming you’ve soldered some headers onto the six-pin interface), and connect some wires…"

"On this site we have published complete directions on how to make your own sentry gun, which autonomously tracks, aims, and shoots at targets…We are a unique project in that everything we do is completely open-source. This includes 100% of our code, as well as our electrical schematics, and even the CAD design files for our Standalone Controller. Our system has been used on six continents and in more than 20 countries (so far), and is even used by the Australian Navy in their training program."

"The display consists of 7 LEDs in a vertical row. By moving them fast enough back and forth over each other, I can display a message which appears to be generated by a 7*n matrix of LEDs and not a single column of LEDs."
