Hi, Fireboat.
I realise that this particular thread is a couple years old by now, as too is the above URL which you'd posted. instead, this link will take you to the index page...

...and from there Captain Pugwash will find a couple circuits for R/C switchers under 'R/C Gadgets' on the left-hand menu. Unfortunately neither of those switchers are of the latching type, but if he (Cptn' Pugwash) would like to email me, I could perhaps offer a PIC-based latching circuit - that is if he is still in need of one.
Also, while you're there, could tell me please why I'm having trouble with uploading my avatar Image? I'm doing everything by the book, but for some reason the Image refuses to appear.
Top thanks to you.
