Build log for my DC controller
Got to Paul's around noon on March 9. There are some chips that have not arrived as yet. But there is stuff to do - cut the copper sheets for the capacitors, get them bent, drill out pilot holes in the copper sheet, finish drilling out and tapping the second controller cooling plate.
The insulating (mylar?) sheet between the copper sheets .. we used the stuff that's rated for 800V. It's tough to cut! And not all that easy to drill. And it moves around a lot ... we ended up needing to make some of the nice round holes that are in the copper sheets ... into ovals. But they will work.
The bending of the copper sheets requires too much precision right now. The next iteration will need to allow for some additional material to be taken up by the bend, and some slop so that bends that are not perfect can be used without modifying the holes!
I have some video, and some audio ... but the camera batteries did not last so I have two different views for the first while, one view for about half an hour when I noticed that the cameras had stopped running ... and no video for the last hour. I'll try to salvage something - perhaps a time lapse would be possible.
The chips should have arrived on Wednesday afternoon .. but they arrived on Thursday afternoon instead.
I'm sure that more was done .. but that's all that I can remember!
