Thanks for the comments. I have some other armour based on automail from full metal alchemist, I'll be posting some pics of that when I have a chance to take them :P
In a comment to a previous post, Parallel Reality Hero asked, "Are you studying electrical engineering?"
Sort of, in england we have a post mandatory education system that helps us to specify our knowledge for certain workplaces. The system helps us prove that we have the required knowledge by passing tests called NVQs or Nation Vocational Qualifications.
I have so far taken NVQs in Business/Administration, Mechanical Maintenance, CAD(Computer Aided Design - Engineering drawings on computer) and I am currently undertaking an NVQ in Electrical Installations.
I also attend a college on wednesdays where I am studying to pass a Higher National Qualification in Electrical. So in short, yes, I think I am ;)
Check back tomorrow sometime and I will have (hopefully) posted how that control circuit works.
Also coming soon: Instructions on building a basic DC motor from scratch.
