Aloha,
I don't know. I originally would have agreed that the Boyce system seems to complex.
But if you want results, maybe it's not a bad alternative. It can be built in steps. Done this way, it's probably not as hard as it seems.
I have been building and researching for over three years. I think now I probably would have saved a lot of time and money just building a variation of Bob's system to begin with.
The only thing I don't fully understand is why he builds his WFC the way he does. His plates are 6"x6" (36 sq. in.) but only the lower 3" can be used. Thats 18 sq. in. of used plate surface. If the plate was 3" wide and 12" tall (36 sq. in.), then 27 sq. in of surface could be used, leaving the needed 3" at the top for the heavy bubbling.
Also, I don't know if anyone has successfully used Bob's electronics with other WFC configurations.
Bill
