Battery powered electromagnetic lock with additional safety mechanisms

Hello! First post here.

I'm currently working on a portable (small) electromagnetic lock that's remote controlled by a PC, and has a few additional safety features (fire alarm, earthquake). All custom designed hardware.

The project is already underway, and most of the electronics design is already done.

(A lot) more details on my blog: http://tinatiedup.wordpress.com/
There are also a few other project ideas I have in mind on there.

Comments highly appreciated! Especially experience working with electromagnets.

Thanks!
Tina

I think we have a couple of related forum threads and blog posts.

Yeah I did see them. That's why I decided to share my project here. Thought someone may have done similar things already.
