Source the parts

DIY EDTracker is based on the popular Arduino platform. At it's core is the SparkFun Pro Micro development board, coupled with an Invensense MEMS gyro sensor (various models available). To bring the parts together into something useable, there are a variety of options. You can make up your circuit in some breadboard or prototyping board, or you can etch your own PCB if you are so inclined. Alternatively, we offer a custom-made PCB that brings all the components together into a single, neat package. You can even wire the boards directly together if you really wish! Here's a summary of what you need to make a DIY EDTracker...

SparkFun Pro Micro (Arduino) development board (or clone) based on the ATmega32u4 16MHz Atmel microcontroller

(NB: NOT Micro/Pro Mini - must be USB based using the ATmega32u4 Atmel microcontroller and have 24 pins)

GY-521 MPU-9150/9250/6050 5v development breakout board

We strongly recommend you go for the 9150/9250! The 6050 does not have a magnetometer built-in; results are better with the 9x50 series. If you're using a 9250, please read this article.

Tactile switch or button, momentary push-to-close

The PCB design expects a 6x6mm momentary button, but if using breadboard you can use any suitable button. Not essential - you can leave it off if you wish.

If you want to make it doubly easy on yourself, you can order our custom PCB from ourselves to simplify your build even more. The electronics components can be sourced from places like eBay but we've partnered up with a couple of places who now sell EDTracker DIY kits of varying specification, including our own PCBs so you can get all the bits in a single shop... 

On top of that you'll need the following tools to construct your device...

  • A soldering iron
  • Some solder
  • Some short lengths of wire (if using breadboard/protoboard)

...and, while not mandatory, the following may help improve or ease your building experience...

  • A Panavise/Helping Hands/Bench Vice or something to hold your work while you solder it
  • If you intend to etch your own board, you'll need all the related kit (etching bath, ferric chloride etchant, gloves, copper-clad board, zip tie, and a method for printing the pattern onto the board)

Once you've got all yours bits, you're ready to assemble it...
