For 5th February 2015. Part of my Upload 1 model a day in Open Source format New Years resolution. Things are going well. I need this for work so I decided to design in my own time, wire up and print out. This is the 3rd Generation, but looks good. Model of the board is at: http://www.thingiverse.com/thing:662394 Wire the board, rotate the board under notch and onto spikes (gentle encouragement) and then use your soldering iron to melt the pins to hold the board securely. I will let you know how I progress with this tomorrow as I want to measure an acceleration on this. It allegedly outputs a set voltage per "g" acceleration, so I can maybe track this with a USB Oscilloscope we have. That'll be sweet! All the best, Eur Ing Andy Southern Bath Robotics. Printed out (gen2) shaved the edges (gen2) and then slowly eased the GY-61 ADXL335 Accelerometer Analogue Board (http://www.thingiverse.com/thing:662394) around over the pins (gentle encouragement was needed). I then used a soldering iron to splay the pins out and retain the board.
