I spent a few minutes this morning and designed my version of the SB. When I have a chance (trout season opens this weekend), I will build, install, test and post drawing, pictures and instructions, if it works or doesn't.


I haven't looked into sourcing the connectors, so I will probably hard wire the prototype. If any one has info on the connectors, I would appreciate any help. With the connectors I could build a nice plug in unit like the SB.

I chose a fairly expensive dual op-amp ($7) so I'm looking at around $12 in parts without connectors.
