I have been thinking about this very thing recently. It's actually pretty
simply. For the simplest version, all you need is a nail or screw
(preferably with a lot of soft iron in it, otherwise it will tend to stay
magnetized to some extent once the current is stopped) and "magnet wire"
which you can find a Radio Shack. Magnet wire is just really thin,
insultated wire.

Basically, you want to wrap the magnet wire areound the nail in an even
coil. You shoul make at least 3 passes, but do not create a coil that's more
than twice the size of the diameter of the nail. Also make sure that the two
ends of the magnet wire are a opposite ends. That's really about it. Just
attach the (stripped) magnet wire ends to a LEGO wire and your done.

Hi there,

Being a *complete* dufus when it comes to things like electronics, I've no
idea how to start creating my own sensors, but I feel I have to start
somewhere.

I've thought about creating a LEGO Electromagnet (uses the motor • connectors
to be turned on and off) so you can create robots that pick up things. Any
ideas how I might go about doing this?

Regards,

James.

Thanks it worked! I had some magnetic wire from a Stiquito set I just built, to I managed to get a simple one working, but I couldn't connect it to the RCX for some reason. I'd attach it to one of the LEGO wires (do the order of the connectors (...) (24 years ago, 15-Apr-01, to lugnet.robotics)
