My Robot Has WiFi!

Wireless communication using Bluetooth! Thanks to the Adafruit EZ-Link!  Basically that tiny board sticking out on top is a Bluetooth Serial-Link, allows me to remove the cable that binds the robot to my PC / MAC.  Now I cannot only program the robot wirelessly, but if I choose to, I can send it commands wirelessly over the air – thus completing Asimov’s second rule of robotics (if you don’t know the…

It Can See; Giving Your Bot Sight!

Previously we unveiled our love for the Arduino and the Zumo Shield that gives us a massive head start to building our own robot army.  The basic shield has a Zumo reflectance sensor array for primarily line following, and an LSM303DLHC accelerometer & magnometer (magnet-o-meter) for navigation.  But a lot of the remaining Arduino pins are not used, so this gives us the capability to add more tech or sensors so our robot can…

Rise of the Machines: Arduino Bots

Robotics Week Its robotics week (April 5th – 13th) 2014 (http://www.nationalroboticsweek.org), on Arduino Day (29th March 2014) I posed the question “What will you Build?”.  Well here in the Pentura office, we went out and bought some Zumo Shields from Pololu.  The shields are also available from our favourite electronics provider Adafruit.  The shield is a quick an easy insertable arduino shield that slides perfectly into place on an Arduino Uno R3…

iClass Is Not Enough

Hacking iClass for Fun, Door-Entry and a Free Lunch.  iClass has been broken in the public domain since approximately 2010 when Meriac published his findings at the 27th CCC in Berlin with the Heart of Darkness White-paper.  But why does there appear to be limited support for hacking these cards within the community? The cards have been in the industry since 2001, boasting stronger security then the original Mifare.  Since…

[SOLVED] Arduino UNO – Can’t Upload Sketches Larger than 30KB

Introduction Relating to the previous Gamby post, many people may have trouble uploading some of the game sketches to their UNO board as they are over 30KB.  The ATMEGA 328P (chip on the UNO) should allow upto 32KBytes of memory; but then people forget there is the addition of the bootloader which in older models occupies 2KB of memory. The bootloader is a special piece of software that makes reflashing…

Gamby: Retro Style Gaming on Arduino

What is a GAMBY? Gamby – the Games for Arduino Made By You! When I’m personally not security testing, I like to chill out, play games, play with electronics kits, and usual stuff like family time.  I think its important to remember to leave work behind on the Friday, have some fun over the weekend, and resume the work life on Monday. Today, I received my Gameby kit after seeing…
