well, you can pretty much forget about 'local shops' in the US. In Columbus, OH there was one shop that sold NTE transistors and Radio Shack has pretty much nothing useful. Here in Chicago, ditto, though I have not made it to the one shop in Niles, yet, to see what they have. I am pretty much set wi...

with regard to the smd fets... one example is the vnd5n07 (my favorites, actually). I have a sleeve of these in ipak format. These are the ones that are 'omnifets'. Current limited, thermal protected, short circuit protected, etc. The through hole ipak version is not available any more, though the d...

A couple comments. I like the to-220, but I have recently been converted to Dpak. TO220 seems to be hard to find in some of these protected FET devices and even some IGBTs. Interestingly, if these are placed in line on one end of the board, a bar could be clamped across them as a head sink. These ar...

None of these systems are particularly effective because of the exterior noise. What I would like to do is figure out an analog filter circuit that not only removes a lot of the garbage noise, but is synced with the engine phase for windowing. I propose that this could be done by having an analog p...
