I am a test development engineer by profession. I do Arduino and TI Launchpad mostly as a sideline. I have been using the Arduino for more than 5 years now. I have been using the TI Launchpad platform for more than 2 years. I have had projects using wireless connectivity like xbee, gsm/gprs, rfid, wifi, bluetooth, the use of gps, converters like ADCs and DACs, mems sensors like accelerometers and gyroscopes, and a number of other sensors for various applications ranging from personal impact sensors to data acquisition modules to automated cryo control and monitoring. I have a mini bench lab complete with soldering station, multimeter, an oscilloscope, drills and a bunch of other tools. I design and assemble my own or the client's shield, boosterpack or standalone boards.
