Hardware - attie.co.uk. I enjoy working with electronics, and will be adding to the list of project write-ups from some of my projects here. My current project is an Electronic Speed Controller. For use on my Quad Copter. Just loads of sensors in a box! Projects That I Want to Do. XBee Relay Control Board. A basic PCB with an XBee mount that will be able to drive 8 relays. Projects With Write-Ups to Come.

Progress Log - attie.co.uk. Quad Copter Progress Log. Recent entries are at the top. Click on the date heading to show / hide an entry, or use the following buttons show all. So I've looked into filtering, and come up with the following sallen-key / low pass / schmitt combination. This gives a fantastic improvement over the previous filtering - the comparator was previoulsy working with a few-hundred milivolts, whereas now there is a good 6v signal! Here, blue is the BEMF signal (V. I've been thinking ab...

Projects - attie.co.uk. I really enjoy working on projects. Much of what I do is software oriented, but I also enjoy electronics and other hands-on opportunities. Projects - such as hybrid hardware and software projects, or even completely non-technological projects. Here is a list of projects that I want to do, some are partially implemented as proof-of-concept, while others are mere ideas:. Needs to handle: git, hg, svn, cvs, fossil, etc. Provide simple mirroring and update features, etc.

Quad Copter - attie.co.uk. Photo by flberger - Source. My new home project is to build as much of a quad copter as possible. By this I mean designing, building and developing the speed controllers (ESCs) and the flight control board as well as the software that runs on both of these systems (and possibly more! A Boeing AH-64 Apache helicopter. If you would like a more in-depth explanation of helicopter operation, this. Is a good website. A quad copter in plus ' ' configuration - Source. Well this isn't a...

Libxbee - attie.co.uk. Libxbee started as a small library for myself, but quickly grew. I also noticed that there are seemingly no other XBee interface libraries available for C (there are a handful for other languages and platforms - python-xbee for Python, xbee-arduino for Arduino, etc.). If you find libxbee useful, then I would really appreciate a donation. Please feel free to use the PayPal button to the right. To be cleaned up). How To Reflash an XBee Module. Feb 2012 - ongoing.

Getting Started - attie.co.uk
http://attie.co.uk/libxbee/getting_started
Getting Started - attie.co.uk. I've had quite a few people getting in contact asking for support with the initial setup and configuration of libxbee. As a result, I felt that it would be worthwhile writing this guide. libxbee is very straight forward, once you understand the principals involved. Is there anything I should know before I dive in? How do I get the source code? Can I download compiled binaries? How do I get it running on my OS? Which modules should I use? How should my modules be configured?

Libjson - attie.co.uk. Libjson is a lightweight C/C library, designed to provide support for parsing, building and accessing data stored in JSON format. It is still under development (currently the C interface doesn't exist), and I'm sure that there will be a few bugs to iron out, and features to add. This sample code can be found in the repository. Libjson - a C library to parse and construct JSON data structures. Libjson is free software: you can redistribute it and/or modify it. GNU Lesser General Pub...

Software - attie.co.uk. Software development plays a fairly large role in both my personal and professional life. I like to make my computers work for. Me, rather than with or against me. But you never know. (kudos to Dmitry by the way). I feel that 'open source' is a really great movement, and have released a few of my projects for others to use. A C/C library to interface with XBee modules and their wireless network. A C library that provides fast, flexible and efficient buffers.
