This is how you show a free-wheeling diode (MUR1560) its place.

Yes, but this is the most common color for mechanical machines in italy, almost the 40% of lathes are green here! smile

How stable is it on those blocks of wood? We always used to bolt floor-standing lathes to the floor and or two-pot epoxy to the floor as well.

If you get a decent mass spinning nicely that then jams for whatever reason (e.g. poor tool feed) the whole lot can tip over...

Today I bought a server unit for 10 dollars from someone on another floor of my dorm. He just had it in his closet! He claimed he didn't need it since he had another one. I don't know anything about servers, and I didn't have the space to store it, so I did what I do best... I gutted it for what it was worth... in my opinion.

Many nice and fast IGBTs all over one board. MOSFETs for high voltage and moderate current, and some super low resistance high current FETs for low voltage. Also Schottkys in large-ish package styles. Also, my heatsink problems will be solved for the next week or so =P and I'm not sure what to do with all these fans... In fact, I'm not even sure what to do with all the wires coming out of the fans! Well, the yellow and blue ones, anyway. Big ferrite cores and some filter capacitors in there, too.

I kept one of the power supplies intact (there were two) and have it currently jury rigged to three very powerful fans (each 12V@ 2.4A!). In case you were wondering, I went through the trouble to confirm that a fan such as this will, in fact, easily cut into one's finger. I guess I'll be playing with my 90 watt fan setup until I get to work on my brick driver! Not sure what else to do with 12V at a maximum of 55 amps! (I'm open to ideas...)
