DIY Basic Cellphone

Posted March 4, 2015 by Chris

"An exploration into the possibilities for individual construction and customization of the most ubiquitous of electronic devices, the cellphone. I investigate the implications of digital fabrication and open-source hardware for DIY practice."

Cellphone Operated Land Rover

Posted February 18, 2015 by Chris

"Conventionally, wireless controlled robots user circuits, which have a drawback of limited working range, limited frequency range and limited control. Use of mobile phones for robotic control can overcome these limitations. It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls."

Flying Android Project

Posted January 3, 2015 by Chris

"In 2009, I was challenged by [govt agency] via GTRI to develop an Unmaned Aerial Vehicle (UAV) which is piloted by a smartphone. In particular, only the sensors on the phone may be used and the flight controller must run on the smartphone. Custom electronics were allowed to interface the phone to the airframe (PHY) but those electronics could sense or control."

Android Powered Robot Tank

Posted October 1, 2014 by Chris

"After half a lifetime of dreaming about it, I’ve finally started building a robot. It’s based on a remote controlled tank, an Android mobile phone and a IOIO board which connects the two via USB."

NFC (Near Field Communication), RFID

Posted July 18, 2014 by Chris

"RFID is known as Radio Frequency IDentification. The technology is able to wireless-ly picking up information from a RFID tag which can be embedded onto most object. Fast and reliable. RFID has helped to rise up our productivity."

Arduino to Android IO on the cheap

Posted May 2, 2014 by Chris

"This article describes how to implement a very low bandwidth one way communication channel between an Arduino and an Android device using nothing more than about a meter of magnet wire, a resistor and diode. Links to a software sketch for the Arduino and the Android source code is included."

Project HiJack

Posted February 1, 2014 by Chris

"HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone’s headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation."

iPhone Controlled Logging Robot

Posted December 3, 2013 by Chris

"The challenge here was to integrate different technologies in a working project. In particular I wanted to use the iPhone to send/receive data to/from an Arduino, build a remotely controlled robot using a WiFi network and hook up a data logger station capturing the different sensor data."

Robot Controlled By Android Phone

Posted July 18, 2013 by Chris

“We decided a few weeks ago to use the Android as a remote controller instead of building a remote control from scratch. We had started developing our android controller with Google Labs App Inventor but one of the guys over at LMR did the same thing and put it on Android Market for $2. So we decided to use Chris the Carpenter’s RocketBot Controller.”

1937 Radio Hacked Into An iPhone Dock

Posted May 25, 2013 by Chris

“I had this old Philips radio laying around that I couldn’t use because it only had an AM receiver. So, I thought it would be cool to make it into an iphone dock =D”
