The Egg Works - Well, Almost

Hey guys,

I was able to power up the egg last night and after figuring out I had one
pair of coils out of phase, I got it working. The egg spins up as you can
see here:

Notice the egg spins, but never stands all the way upright. I am not certain
whether this is due to lack of field strength or if it's caused by the
hollow egg's poor center of gravity. I am going to wind another layer of
12AWG on each coil and see if it improves. I'm looking for another egg too.

Here are some better pictures of the setup:

This is a schematic of Harry Goldman's driver along with a picture of his
system he sent me:

Gary Lau pointed out that the black cylindrical AC caps I had could be
non-continuous duty motor starting capacitors. I confirmed this last night
after running the egg for about 10 minutes and finding them to be rather
hot. It does look like Harry is using these also by the photo. The silver
MOT like AC caps run cold and I'll use those from now on.

Harry was right on with the values in the schematic. I am using actually 16
ohms, because 8 is too low and the resistors I have are 4 ohm. I do notice
that the set of coils the resistor drives runs hotter than the coils driven
by the capacitors. This makes me wonder if there is still too little
resistance. More experimenting and maybe testing with a scope will hopefully
help with this.

More later,
Cameron
