First custom PCB

First custom PCB

This is my first working printed circuit board. I used the toner transfer method to draw the traces on the copper board. The purpose of this circuit board is to drive a stepper motor. This is a proof of concept for the final board version that will complete my equatorial mount project. The equatorial mount will […]

Build a Custom Arduino Clone (Part 3) – Add a Compass

Build a Custom Arduino Clone (Part 3) – Add a Compass

This post is the last part of this series of articles showing how to build a project using a custom Arduino board. To the accelerometer I added a compass. It begins to look more like a forest than an electronic circuit. The compass uses the IC2 protocol to communicate with the Arduino micro-controller. That make […]

Build an Arduino Clone (Part 2) – 3 Axis Accelerometer

Build an Arduino Clone (Part 2) – 3 Axis Accelerometer

I just received a adxl335 triple axis accelerometer breakout board from sparkfun.com. I decided to test it on my custom Arduino board. Make sure, while wiring the accelerometer, to respect the maximum voltage of the device. This specific accelerometer accept a maximum voltage of 3.3v. You can get 3.3v from the Atmega328 Avcc pin #20. You […]

Build an Arduino Clone

There are many different kinds of Arduino boards out there. Most of the time you will find one that fulfill all your needs but, sometime, you may want to build your own Arduino based board. Why would someone build its own Arduino board? Well, I can see two reasons to do that. Reason #1: Size and space […]
