MCM Electronics Daily Deal and Bulk Bargain

Iron Man Hulkbuster Cosplay Suit

Posted April 5, 2016 by Chris

"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.

How To Make A PCB At Home

Posted March 11, 2016 by Chris

"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."

Exploring Voltage Multipliers

Posted December 30, 2015 by Chris

"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."

Mind-Controlled Nerf Gun

Posted August 28, 2015 by Chris

"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…"

Project Sentry Gun

Posted July 21, 2015 by Chris

"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."

A Microcontroller Based Interrupter Gear

Posted May 29, 2015 by Chris

"During World War I and slightly before World War II, military fighter aircraft had machine guns mounted to fuselage of the plane. These machine guns were mounted right behind the propeller. The first question that comes to mind is how can the gun fire and not hit the propeller blades as they are spinning? Some planes had special steel plates mounted to the propeller to keep the bullets from shredding the propeller."
