I'm currently working on building an Electrical Discharge Machine (EDM) based on the plans by Robert Langlois. For those who don't know what an EDM does, it basically uses a bunch of electrical sparks to machine away metal. You can use it to do things that are difficult, if not impossible, to do any other way. Depending on the shape of the electrode you can make square holes or use it to cut or make holes in materials that are to hard to use normal machine tools on. A good example of this would be to use it to remove a broken tap in a hole.

Below is the component side of the Langois EDM. The IC's aren't in the sockets yet. I'm leaving them out for now so I can test the board as per the instructions.

This is the foil side of the same circuit board. A friend is planning to build this as well so when he had the pcb made for himself he had a few extras made for the people he know who were also planning to build one.

I plan on putting more information on this page as the project progresses.
