Hi Danno,
I fiddled around with some ideas when I had my 50, but never built a working model.
Doesn't require drilling holes. I haven't solved the temp probe problem, but I think it could be done with slip rings and brushes on the rotating shaft (like rotating signs) if you really wanted it. No power inside the unit either.
Also, have a much easier design which requires drilling a couple of holes and using the same bushings that CS uses for the vent holes. You can buy them directly from CS.
If you'd like, send me a private message and I'll tell what I figured out.I have some rough drawings too.
Either appear doable if you are a bit handy and want to put in the time and $$$.

Sorry couldn't resist.
