You know how you tell the difference between a pro pool player, and an amateur? The pro chalks his cue *before* the shot.

I like that you chose maintainability as a goal from the get-go, cos it saved your ass. Cool piece of work.

I like that Saz didn't mince words about what was hard or took a lot of trial-and-error to get it right. It really does require a sustained effort to make any device sleek, compact, functional and looking "finished". This one is an inspiration.

When I heard that oxygen and magnesium hooked up I was like OMg.

Hey Saz,

This looks like a really cool project!

I had a look on your website...I was just wandering: Do you have a part number for the IGBTs you used in this design?

Hey Bob. Thanks! I resolved to not provide part numbers, plans, schematics, etc for this project. But do a search on Mouser for small package, high current IGBTs and I think you could find them.
