No, I've never gotten around to it. I do use the Sophia. But, believe it or not, I still haven't gotten around to putting it in a tank. I've been using it as a dripper so far.
I'm very, very, very slow to do new things.
As a matter of fact, I had just come online to ....* about RBAs when I saw your post. I don't have the greatest eyes and get frustrated very easily. I frequently work on an RBA for a while, then get too frustrated and just put it away. This time it was a Mini EK clone.
Actually, the Sophia is very easy to build. Very surprising considering how small it is. I really like the ceramic cup design.
Ooh, I just thought of the perfect tank for the Diver V2! I don't have many 35 mm
tanks. I just broke my favorite one. But, I just remembered a plastic one I have put away. As soon as I find it, I'll give it a try with the Diver V2.
